KTU researchers explore using soil for heat storage http://l24.lt/en/education/item/416702-ktu-researchers-explore-using-soil-for-heat-storage http://l24.lt/en/education/item/416702-ktu-researchers-explore-using-soil-for-heat-storage KTU researchers explore using soil for heat storage

When spring arrives and the heating season comes to an end, keeping warm becomes less of an issue. However, scientists remind us that it is not just a seasonal necessity – heat is also a valuable energy resource that can be stored and used when needed most. Researchers at Kaunas University of Technology (KTU) have discovered an innovative solution beneath our feet: using soil as an efficient thermal energy storage system.

KTU professor Dr Tadas Ždankus and his team have been investigating how the ground can serve not only for construction purposes but also as a medium for heat storage. At the core of their research is a ground-based heat accumulator that would store excess energy underground and make it available when demand peaks. “Our goal was to convert heat, which would normally dissipate into the ground as waste, into a useful energy source,” explains Dr Ždankus.

Underground heat storage potential
At the beginning of their research, Prof. Ždankus and the team explored how wind energy could be used to produce heat instead of electricity. Instead of a conventional generator, they employed a hydraulic system. The researchers found that so-called hydraulic losses, typically seen as inefficiencies, were actually generating usable heat. “The hydraulic losses we were trying so hard to eliminate turned out to be nothing less than heat generation,” says a KTU professor.

However, a portion of this heat was lost before reaching the buildings it was meant to warm during colder seasons. “The question became how to not only reduce heat loss to the ground but also store and retain it for future use,” adds Ždankus.

To test this idea, the researchers conducted experiments using an artificial heat source placed in surface soil layers. They measured how heat spreads, how fast it moves, and how long it persists in the ground. In one test, the soil was heated to the point where moisture began to evaporate – triggering a phase change, in which liquid water becomes vapor.

“Phase change can be an efficient way to store heat. The significantly higher amount of energy can be charged into the soil,” explains a KTU professor.

As vapour travels through the ground, it distributes heat over a wider area. “We noticed a sharp temperature rise wherever the vapour flow reached. This means the energy is moving and can be controlled,” says Prof. Ždankus.

Such a system could help balance district heating networks or alleviate stress during power grid overloads. “It’s also possible to install thermal accumulators for individual use – beneath residential buildings, streets, or parking lots,” he adds.

This research demonstrates that underground heat storage can be far more efficient than previously believed. In addition, similar principles could apply to cooling. “Underground cold or coolness storage is also possible,” notes a KTU expert.

Turning ground into an energy cell
Once the feasibility of underground heat storage was confirmed, researchers began exploring its practical applications. They wanted to see if the soil beneath buildings could passively store heat, making use of the natural downward flow of heat from buildings into the ground. “We started in the laboratory. A prototype ground energy cell was developed alongside a testing setup to study how heat spreads through the soil. Temperatures were measured at various depths, including at the surface and in the air,” explains Dr Ždankus.

The team examined how long the soil retained heat and how quickly it returned to its original temperature. These findings helped assess the long-term reliability of such a storage method.

KTU master’s students were also involved in the project. Measurements and calculations spanned an entire year, which enabled the team to monitor seasonal effects and compare results with existing climatological data. “The year-long measurements revealed natural seasonal patterns in soil temperature and allowed us to identify several trends,” the professor shares.

Additional numerical simulations were performed to evaluate potential heat losses and the effectiveness of heat storage under buildings. “We found that even the passive use of an isolated soil volume beneath a building can reduce heat loss and increase its energy efficiency. Less heat loss means less energy needed for heating, which in turn leads to energy savings. If that heat comes from burning fossil fuels or biomass, our solution also lowers carbon dioxide emissions,” notes Ždankus.

To make these ground-based storage systems viable for widespread use, researchers are now developing scaled-down prototypes and refining heat distribution control methods. According to the scientist of the KTU’s Faculty of Civil Engineering and Architecture, the project is evolving through collaboration with experts in various fields – from geotechnical engineers to energy system specialists.

“Our immediate goal is to integrate existing solutions, such as boreholes, piles, and other underground heat exchange technologies into a system that can benefit both industry and residential sectors,” he concludes.

Lithuanian Physicists: the Šarpis Brothers on CERN’s Latest Discovery That Sparks Hope for Understanding Matter http://l24.lt/en/education/item/416658-lithuanian-physicists-the-sarpis-brothers-on-cern-s-latest-discovery-that-sparks-hope-for-understanding-matter http://l24.lt/en/education/item/416658-lithuanian-physicists-the-sarpis-brothers-on-cern-s-latest-discovery-that-sparks-hope-for-understanding-matter Lithuanian Physicists: the Šarpis Brothers on CERN’s Latest Discovery That Sparks Hope for Understanding Matter

Scientists from the Large Hadron Collider beauty (LHCb) collaboration at the particle-physics laboratory at the European Organization for Nuclear Research (CERN) have made a significant discovery that expands our current understanding of matter and antimatter in the universe. This breakthrough was first presented on 24 March at the ‘59th Rencontres de Moriond 2025’ scientific conference in Italy.

The findings of this study have also been published in the prestigious scientific journal "Nature", uncovering the mechanism behind the asymmetry between matter and antimatter in the universe. This enigma has remained unsolved until now.

Dr Mindaugas Šarpis, a researcher at the Faculty of Physics of Vilnius University (VU) and head of the CERN LHCb Vilnius experimental particle physics research group, explains that we live in a matter-dominated universe.

"Antimatter has opposite quantum properties to matter and is essentially a mirror image of the latter. One of the key goals of the LHCb experiment, with around 1,800 people involved, is to uncover the fundamental differences between matter and antimatter," said the scientist.

New insights from particle decays
According to the VU researcher, the Standard Model of particle physics, known as the most accurate scientific theory to date, explains only a tiny fraction of this asymmetry. This implies that there is still much we do not fully understand. In the LHCb experiment, differences between matter and antimatter were observed in particle decays where no such asymmetry had previously been detected.

"All previous studies had only observed asymmetry in the decays of mesons (particles composed of two quarks). For the first time, LHCb collaboration has identified such a difference in the decays of baryons (particles made up of three quarks). This is a particularly significant discovery, as most of the matter in the universe is baryonic, including protons and neutrons (which are also baryons, consisting of three quarks), and hence all the atomic nuclei, chemical elements and molecules," explicated Dr Mindaugas Šarpis.

Statistically significant discovery
Dr Gediminas Šarpis, a physicist working at CERN in Geneva (who also happens to be Mindaugas’ brother), notes that the findings emerged from the decays of Lambda-b baryons. ‘The latest discovery is statistically highly significant and raises hope that the differences between matter and antimatter may extend across many similar systems. This is a truly important breakthrough," said the researcher, who was a scientific reviewer for the study.

Dr Gediminas Šarpis has been studying baryon particles for nearly a decade. His doctoral research focused on searching for matter-antimatter differences in a similar system that can be differentiated by just one quark. The physicist says that while he did find evidence at the time, its statistical significance was too low.

According to the particle physicists, it took seven years to confirm the result of this study. "The statistical significance of the result is 5.2 sigmas, meaning the discovery is confirmed at a ratio of 1 in 5 million. CERN scientists analyse vast amounts of physics data. This analysis involved working with an array of approximately 10 petabytes of data." Likening this to a relatable analogy, the brothers Mindaugas and Gediminas Šarpis explained: "If we had created a video about our colleagues’ work, it would be equivalent to 5 million high-definition feature-length films."

The brothers have been analysing CERN data for over a decade
Gediminas and Mindaugas Šarpis were the first Lithuanians to join the LHCb collaboration. The brothers – both members of CERN’s LHCb – have been analysing particle physics data for more than ten years.

According to them, the technologies developed at CERN bring added value not only to scientific progress and knowledge but also to innovation development.

"The opportunities for Lithuanian researchers and students to contribute to world-class CERN scientific research have grown significantly. Lithuania’s involvement in such large-scale experiments as the LHCb also benefits the private sector, the economy, and the country’s competitiveness," noted the physicists.

In the autumn of 2024, the LHCb Collaboration Board approved VU as a new Institute within the prestigious LHCb experiment.

CERN, the world’s largest particle physics laboratory, unites scientists from over 100 countries. Located on the border between Switzerland and France, it enables researchers to conduct experiments to understand elementary particles and their interactions better. Particle collisions occurring in the 27-kilometre-long Large Hadron Collider (LHC), situated 100 metres underground, allow scientists to search for new particles and phenomena, helping to unravel more of the universe’s mysteries. In 2018, Lithuania became an Associate Member of CERN.

Innovative hydrogen production: scientists eliminate tar in gasification http://l24.lt/en/education/item/416544-innovative-hydrogen-production-scientists-eliminate-tar-in-gasification http://l24.lt/en/education/item/416544-innovative-hydrogen-production-scientists-eliminate-tar-in-gasification Innovative hydrogen production: scientists eliminate tar in gasification

As the global demand for sustainable energy solutions continues to grow, Lithuanian researchers have taken a step forward by developing a technology that not only transforms waste into valuable hydrogen but also eliminates a long-standing issue in gasification – the presence of tar. This new method offers an efficient and eco-friendly way to produce high-purity hydrogen from various waste materials, representing a significant advancement in clean energy production.

Hydrogen is a key element in the transition to cleaner energy. However, conventional gasification methods are often unable to ensure its high purity – synthesis gases contain very low concentrations of hydrogen.

This inefficiency limits the industrial application of hydrogen as a clean gas fuel, highlighting the need for more advanced production methods.

To address this, Kaunas University of Technology (KTU) and Lithuanian Energy Institute (LEI) scientists have developed a two-step conversion system: an updraft gasifier followed by a catalytic reforming reactor.

Increased hydrogen production
The process begins with gasification, where waste is heated in a controlled steam-oxygen environment to produce syngas, also known as synthetic gas.

“Gasification treatment is an emerging, promising, and eco-friendly technology that can convert waste into syngas as a major product besides soot as a by-product,” says KTU Chief researcher Dr Samy Yousef.

However, the produced syngas contains tar, which not only reduces efficiency and can damage equipment due to corrosion effect but also interferes with hydrogen production by affecting key chemical reactions. To solve this, the syngas is passed through a catalytic reforming reactor to break down the tar into smaller molecules. These catalysts also enhance chemical reactions that increase the hydrogen content of the syngas, reaching up to 60 vol%, making it a cleaner and more efficient fuel source.

According to the KTU expert, a crucial factor in this technology is the choice of catalysts used in the reforming reactor. That is why researchers tested most commercially available catalysts and laboratory-developed options.

“Experimental results demonstrated the technology’s efficiency under various conditions. Among the tested catalysts, KATALCO™ 57-4GQ proved to be the most effective, as its high surface area, stability, and durability played a key role in breaking down tar and enhancing hydrogen production,” says Dr Yousef.

Can be applied to all types of waste
Unlike conventional gasification techniques, which require high-energy plasma systems or complex pressure-based processes, this new method operates at atmospheric pressure. This reduces the need for high-cost infrastructure and enhances operational safety.

Compared to the dominant hydrogen production method, steam methane reforming (SMR), this new approach offers a more energy-efficient and environmentally sustainable alternative. SMR relies on natural gas, a non-renewable resource, and emits large amounts of carbon dioxide, making it less viable for long-term sustainability goals.

“Unlike SMR, which operates under extreme conditions and requires high-pressure reactors, our method works at atmospheric pressure and utilises waste as a cost-effective and renewable raw material, making it a cleaner solution,” says Dr Yousef.

While the initial research focused on medical waste, the technology has the potential for broader applications. “This technology is versatile and can be applied to various types of organic and industrial waste, including plastics, textiles, and biomass. Before processing, the waste must be collected, sorted, and pre-treated to ensure a consistent composition and size, allowing for more efficient conversion,” KTU expert explains.

When discussing industrial implementation, the researcher highlights that this innovation has reached Technology Readiness Level 5 (TRL5). This level is part of a globally recognised scale that measures a technology’s maturity.

“Being at TRL5 means the technology has been tested in an environment that simulates real industrial conditions using reactors that closely resemble industrial-scale systems and is progressing toward full-scale deployment,” says Dr Yousef.

As research continues, further scaling and optimisation could pave the way for commercial implementation, making sustainable hydrogen production a reality in the near future.

The Method Developed by VU Biophysicists Can Help Accelerate the Diagnosis of Oncological Diseases http://l24.lt/en/education/item/416510-the-method-developed-by-vu-biophysicists-can-help-accelerate-the-diagnosis-of-oncological-diseases http://l24.lt/en/education/item/416510-the-method-developed-by-vu-biophysicists-can-help-accelerate-the-diagnosis-of-oncological-diseases The Method Developed by VU Biophysicists Can Help Accelerate the Diagnosis of Oncological Diseases

Researchers from the Faculty of Physics and the Life Sciences Center of Vilnius University (VU), with co-authors from Harvard University, the University of Toronto, National Cancer Institute and "Light Conversion" developed a method which can improve the diagnostics of cancer and other diseases. A novel multidisciplinary study published in "Scientific Reports", a "Nature Publishing Group" journal, describes how to quickly and accurately analyze the structure of collagen in tissue.

Collagen is a structural protein with various functions related to cell activity. Researchers say that the method, Double Stokes polarimetry, is based on the dependence of the response of collagen to variously polarized laser light.

"Polarization measurements allow to determine the ultrastructural parameters of collagen, which describe its molecular structure. This lets to evaluate the changes in collagen structure appearing during various diseases. Similar methods have been used to investigate breast and lung cancer tissues, among other cancer types, as well as other diseases, such as keratoconus. The changes in collagen structure are related to disease progression and symptoms. The main advantage of this method is its speed, which is several hundred times greater than that of other similar methods. That’s important for its wider application in clinical settings", tells VU Life Science Center's PhD student Viktoras Mažeika.

VU Faculty of Physics' PhD student Mykolas Mačiulis claims that this research will be relevant in the future. "The work done here is fundamental, and we continue doing related research. Next, we'll apply this method to analyze cancerous samples, as well as those of other diseases. Science has to answer society's needs, and disease diagnostics are important for humanity", he adds.

"This work can significantly contribute to the development of oncological and histopathological diagnostics. We hope that this method will allow physicians to more effectively detect subtle tissue changes. Collagen is the most common protein in the human body, so investigation of its structure would allow for more accurate disease diagnostics", states Prof. Dr. Virginijus Barzda.

Biophysicists from the VU Advanced Biomedical Photonics Group are developing nonlinear microscopy methods and devices which can be applied in life sciences, medical, pharmaceutical or materials engineering research. Modern technologies of physics, chemistry and biology are successfully used in oncology.

Hydrogen Use in Spark Ignition Internal Combustion Engines – Scientific Seminar at the Faculty of Transport Engineering http://l24.lt/en/education/item/416195-hydrogen-use-in-spark-ignition-internal-combustion-engines-scientific-seminar-at-the-faculty-of-transport-engineering http://l24.lt/en/education/item/416195-hydrogen-use-in-spark-ignition-internal-combustion-engines-scientific-seminar-at-the-faculty-of-transport-engineering Hydrogen Use in Spark Ignition Internal Combustion Engines – Scientific Seminar at the Faculty of Transport Engineering

On the 17th of March, a scientific seminar was held at the Faculty of Transport Engineering at VILNIUS TECH, where the topic "Hydrogen Use in Spark Ignition Internal Combustion Engines" was presented. The seminar speakers, Associate Professor Dr. Saugirdas Pukalskas, Head of the Department of Automotive Engineering, and Professor Dr. Alfredas Rimkus, shared the latest scientific research to better understand the potential of hydrogen as an alternative fuel.

The seminar featured the R&D project "Use of Green Hydrogen in the Transport Sector," implemented under the project "Implementation of Mission-Oriented Science and Innovation Programs" No. 02-002-P-0001, under the theme "Smart and Climate-Neutral Lithuania." The goal of the project is to create a hydrogen supply system for conventional vehicles with internal combustion engines to reduce CO2 emissions in the transport sector and contribute to mitigating climate change.

The project, carried out in collaboration with JSC „SG Dujos Auto“, started in September, 2023 and will continue until April, 2026. During this time, a hydrogen supply system will be developed and tested, allowing part of the conventional fuels (gasoline or diesel) to be replaced by green hydrogen produced from renewable energy sources.

Project Goals and Results

One of the main goals of the project is to reduce CO2 emissions in the transport sector, where emissions make up a significant portion of all greenhouse gas emissions. The results of the project include:
• Six scientific articles on the possibilities of hydrogen use in the transport sector;
• A hydrogen supply system prototype and model, developed in collaboration with SG Dujos Auto;
• A research report summarizing the research and results obtained.

In addition, the project activities include the simulation of combustion processes for mixtures of hydrogen and conventional fuels, as well as driving modes of vehicles, the development of the hydrogen supply system, experimental engine tests, engine durability studies, and system improvements and adaptation for use in vehicles.

Climate Change Challenges and Hydrogen Potential

Project implementers emphasize that one of the most pressing global issues today is climate change, particularly due to CO2 emissions, the main source of which is the transport sector. To contribute to the reduction of these emissions, the project will test a hydrogen supply system that will allow the replacement of part of traditional fuels (gasoline or diesel) with green hydrogen. This technology could not only reduce emissions but also help achieve a more sustainable and low-pollution future for the transport sector.

The project plans to acquire unique hydrogen production and engine testing equipment that will allow the study of hydrogen usage possibilities in spark ignition internal combustion engines. Additionally, various tests will be conducted with different hydrogen and conventional fuel or biofuel ratios to find the most efficient ways to integrate these fuels into vehicles.

Insights of the Scientists

Assoc. Prof. Dr. Saugirdas Pukalskas, speaking about hydrogen use in the transport sector, emphasized the technological challenges associated with integrating hydrogen into existing internal combustion engines. He presented his research on various methods for using hydrogen and other alternative fuels, as well as discussed possible engineering solutions that could ensure the smooth application of these technologies in vehicles.

Meanwhile, Prof. Dr. Alfredas Rimkus presented research and its results, analyzing the effects of hydrogen on the performance of spark ignition internal combustion engines. Initial experimental tests were conducted at VILNIUS TECH laboratories, and based on them, an article on hydrogen's impact on vehicle energy and environmental characteristics was published in the journal Applied Sciences. In the study, dual fuels (gasoline and hydrogen) were used. In the first part of the research, tests were conducted by injecting 5% hydrogen into the engine's intake manifold, and energy and environmental performance "maps" were created for different operating modes. In the second part, a numerical simulation of the vehicle’s "WLTC" driving cycle was conducted, which showed an increase in energy efficiency and a reduction in emissions of pollutants such as CO and CH. However, it was noted that nitrogen oxide emissions increased due to more intense hydrogen combustion. As experimental tests continued, significantly increasing the hydrogen concentration in the internal combustion engine fuels highlighted more of hydrogen’s positive properties and challenges. Based on already known technologies and new solutions, hydrogen usage research is ongoing, and in the near future, plans are to test a vehicle on the road that would have a significant portion of its fuel made up of hydrogen.

Scientific Research and Innovation

The research results presented by the seminar speakers, Assoc. Prof. Dr. Saugirdas Pukalskas and Prof. Dr. Alfredas Rimkus, confirm the potential of hydrogen as a clean energy source capable of contributing to CO2 emission reduction. Professor Dr. A. Rimkus presented research on the efficiency of hydrogen use in internal combustion engines, while Assoc. Prof. Dr. S. Pukalskas discussed various technological solutions that would help integrate hydrogen into modern vehicles.

The seminar participants actively engaged in discussions about hydrogen’s potential as an alternative fuel and its role in achieving a climate-neutral transport sector.

On 1 April, Vilnius University (VU) will mark the 446th anniversary of its establishment. On this occasion, VU invites its community and the public to participate in various festive events, both traditional and specially dedicated to this anniversary.

One of the highlights of the festivities is the solemn inauguration of Prof. Rimvydas Petrauskas as the Rector of Vilnius University. In addition, a special lecture, “The Legendary Toga of Petras Skarga and the Oriental Pattern Cloak”, will be delivered by Assoc. Prof. Miglė Lebednykaitė. In this lecture, you will learn about one of the exceptional values of Lithuanian cultural heritage – the academic attire of the first Rector of Vilnius University, Petras Skarga, symbolising the beginning of the history of Vilnius University.

An Exceptional Exhibition

On 1–2 April, Vilnius University community and the public will have a unique opportunity to see some elements – the pelerine and the biretta – of the academic attire of the first Rector of Vilnius University, Petras Skarga. These historical relics, preserved for over 400 years, were last exhibited together in 1936. Having been rediscovered almost a century later, they will now be presented to the public on a special occasion – the inauguration of Prof. Rimvydas Petrauskas as the Rector of Vilnius University.

On 1 April at 11:00, the discoverer of these historical relics, Assoc. Prof. Miglė Lebednykaitė, Head of the Ethnography and Anthropology Division of the National Museum of Lithuania, will deliver the lecture “The Legendary Toga of Petras Skarga and the Oriental Pattern Cloak” in Vilnius University Theatre Hall. The audience will hear about the search process of Petras Skarga’s academic attire, the research conducted, and the unexpected discoveries made.

Another unique event is an art and science project, installation-performance “U”, which will take place on 3–5 April, starting from 20:00, in the Grand Courtyard of Vilnius University. Artist Akvilė Anglickaitė and her team will create an installation of light, sound, and street art, inspired by the Foucault pendulum. The performance will feature a choreographed skateboarding sequence immersed in light, with live music provided by the VU Wind Orchestra “Oktava”. There will be three performances every evening between 20:00 and 21:30.

“Scientific Sprint” – a Race of Ideas

This year, the tradition of holding the science communication competition “Scientific Sprint” in celebration of VU’s birthday continues. On 27 March at 18:00, the “Artistai” pub will host 14 teams consisting of lecturer and student pairs. In just three minutes, each team will have to present their research or idea in an appealing and engaging way.

Participants will be judged by a commission composed of scientists and communication experts. Three teams with the highest scores will share the EUR 1,000 prize established by “Thermo Fisher Scientific”.

This year, teams from the Faculties of Medicine, Physics, Philology, Philosophy, Chemistry and Geosciences, Kaunas Faculty, and the Life Sciences Center will be participating. The participants of the competition will analyse the challenges of radiation protection of children, the importance of quantum diamonds in medicine, technology, and informatics, the role of the hippocampus in neuronal change, artificial intelligence, climate change, and many other topics that are of great importance and relevance today.

The Exhibition of Martynas Mažvydas’ “Catechism”

On 1 April from 10:00 to 19:00, Martynas Mažvydas’ “Catechism” will be on display in the P. Smuglevičius Hall of VU Library. This tradition allows the public to become acquainted with the first printed book in the Lithuanian language; only two copies are known to exist, one of which is stored in the Library of VU.

In addition, the VU Foundation is inviting you to join a unique initiative and give a symbolic gift of EUR 4.46 to the VU Endowment Fund as a birthday gift to Vilnius University. The donations will be professionally invested and earn a return so that talented scientists can be supported; the funds are constantly reinvested, thus providing benefits to VU in perpetuity.

On 2 April at 19:00, the event beloved by many storytellers and listeners, Storytelling Salon “Per Aspera ad Astra”, will take place. Hosted by professional narrator Milda Varnauskaitė, this event, held in the VU Aula Parva café “Morgas”, will feature stories about the challenges and successes in science and studies.

On 5 April at 12:00, the VU Life Sciences Center will host an orienteering game where VU community members, city residents, and guests are invited to discover important Vilnius University locations in Saulėtekis. The participants, in teams of up to four people, will have two hours to search for historical sites and collect points. The teams that discover the most places and score the most points will be awarded prizes.

Birthday to Reach Culmination in a Concert

On 28 March at 17:00 and 29 March at 13:00, visitors will be able to explore “The Old Campus of Vilnius University Through the Eyes of an Archaeologist”, whereas on 28 March at 12:00 and on 2 April at 17:00, visitors are invited to get to know the Baroque and Jesuit heritage on the excursion “Saint Johns, Baroque, and the Jesuits”.

On 29 March at 19:00, the Kinetic Theatre’s production of “Hommo in Maxima” will be held in VU Theatre Hall. This experimental performance explores the transformation of four fundamental value categories following Lithuania’s accession to the European Union, and it analyses how the notions of love, human connection, security, and meaning have changed in modern society. The performance reveals how traditional values are transformed into a model of life dictated by efficiency and productivity.

On 5 April at 18:00, the VU Chamber Orchestra invites you to the concert “Returning Generations”, which will feature works by Antonio Salieri, Franz Berwald, and Joseph Haydn. The concert, dedicated to promoting the unity of the community, will feature both current members of the orchestra and its alumni. The event will take place at St Johns’ Church.

The birthday celebration will reach its culmination on 6 April, with the VU Drama Theatre performance of ‘The Promised’ – a fresh interpretation of William Shakespeare’s “Romeo and Juliet”. The play explores the themes of love, responsibility, and guilt, and its creative team offers an exceptional aesthetic vision, combining modern technologies and classical dramaturgy.
