Scientists from the Laser Research Center (LRC) at the Faculty of Physics of Vilnius University (VU), together with an international team of experts, have developed a unique parametric light generator – a source of laser radiation. Their research has been published in the prestigious journal APL Photonics.

This device converts a pump wave in a nonlinear medium into two waves whose photon energy equals that of the initial radiation and whose frequencies can be tuned. The team was pleased to achieve exceptionally high spectral purity, excellent beam quality, and nearly ideal temporal characteristics—features that have previously been difficult to realise.

“The new device, based on the combination of a microlaser generating subnanosecond pulses and a periodically poled nonlinear crystal with a submicrometer grating period, enabled the realisation of laser radiation with exceptionally high spectral, spatial, and temporal quality. Unique light, both forward and backwards,” explained the VU physicists.

“This type of laser source can be used for specialised scientific applications—for example, in kinetic spectroscopy to excite and study ultrafast processes in molecules, where a very narrow spectral bandwidth is needed, and subnanosecond pulse durations are sufficient to observe molecular responses,” said VU physicist Assoc. Prof. Julius Vengelis.

Although this pulse duration is not the shortest achievable by lasers, it is sufficient to observe many ultrafast processes.

Assoc. Prof. J. Vengelis illustrated the timescale by saying: “If light can travel around the Earth seven and a half times in one second, in just 500 picoseconds it only covers about 15 cm—the length of a sheet of paper. That’s an incredibly short moment.”

“We developed the first backward-wave optical parametric oscillator powered by sub-nanosecond pulses from an Nd:YAG microlaser, using a unique rubidium-doped KTP crystal with an exceptionally fine grating period of just 427 nanometres,” explained Assoc. Prof. J. Vengelis.

“We are delighted that our colleagues abroad succeeded in fabricating such a unique crystal and that we were able to use our experience in nonlinear optics to realise this device,” added the VU physicists.

The study was carried out by LRC scientists – PhD candidate Jonas Banys, Associate Professors Vygandas Jarutis and J. Vengelis – alongside Lithuanian researchers working abroad: Dr Jonas Jakučis Neto (Department of Aerospace Science and Technology, Brazil), Dr Andrius Žukauskas, and Prof Valdas Pašiškevičius (Royal Institute of Technology, Sweden).

The researchers measured the spectra of the generated light and pulse durations and assessed beam quality, as well as how all these parameters vary with changes in wavelength.

According to physicists, microlaser-pumped subnanosecond pulse duration optical parametric generators hold significant potential. These devices are compact, have simple construction, and provide a cost-effective source of tunable wavelength laser radiation.

“They are especially useful in applications where high temporal resolution is not required. Instead of using several lasers generating subnanosecond radiation at different wavelengths, we can use just this single parametric light generator,” said the LRC colleagues. They continue to pursue related scientific research and are further developing this laser radiation source.

It is hoped that the study will contribute to the development of more efficient tunable wavelength laser radiation with higher output quality based on subnanosecond pulse-duration microlasers.

The research was conducted under the Universities’ Excellence Initiative program. The project is funded by the Research Council of Lithuania and the Ministry of Education, Science and Sport of the Republic of Lithuania (Project No. S-A-UEI-23-6).

VU LSC Researchers Study the Impact of Climate Change on Amphibians in the Amazon http://l24.lt/en/education/item/417023-vu-lsc-researchers-study-the-impact-of-climate-change-on-amphibians-in-the-amazon http://l24.lt/en/education/item/417023-vu-lsc-researchers-study-the-impact-of-climate-change-on-amphibians-in-the-amazon VU LSC Researchers Study the Impact of Climate Change on Amphibians in the Amazon

Scientists from the Life Sciences Centre at Vilnius University (VU LSC), in collaboration with colleagues from the University of Veterinary Medicine in Vienna and partners in French Guiana, are currently undertaking an expedition to the Amazon rainforest, where they are studying the impact of climate change on amphibians.

The expedition is led by Dr Andrius Pašukonis and includes PhD student Shubham Prashant Soni and Master’s student Edgaras Žigis from the VU team. The research is being carried out in the remote Nouragues Nature Reserve in French Guiana – a research station accessible only via several hours of river travel or by helicopter. The expedition is supported by the Research Council of Lithuania through the project “Drought Impacts on Amphibian Reproduction in Ephemeral Rainforest Pools.”

“We’re studying how tropical amphibians adapt to changing climate conditions. We’re installing environmental sensors to record year-round data on temperature, humidity, water levels, and sound, allowing us to monitor amphibian activity under varying conditions. We’re also gathering behavioural and habitat data on species that remain poorly understood.

Amphibian habitats in tropical forests are incredibly diverse – ranging from temporary forest ponds to the canopy high above the ground. On any given day, the team might find themselves wading through waist-deep water or climbing 30-metre-tall trees using ropes. The heavy rains typical of this season create ideal breeding conditions for amphibians, making the pace of work especially intense – with the team often continuing into the night. Although the work is physically demanding, the team's spirit remains high – we’re full of impressions, and the amount of data we’ve collected is truly rewarding,” says Dr A. Pašukonis.

KTU PhD student: translation can be a career for thinkers, doers, and risk-takers http://l24.lt/en/education/item/416831-ktu-phd-student-translation-can-be-a-career-for-thinkers-doers-and-risk-takers http://l24.lt/en/education/item/416831-ktu-phd-student-translation-can-be-a-career-for-thinkers-doers-and-risk-takers KTU PhD student: translation can be a career for thinkers, doers, and risk-takers

Interpreting and translation in general are often seen as skills confined to conference rooms, diplomatic meetings and offices. However, the job can take translators far beyond comfortable office chairs.

A doctoral student at KTU Faculty of Social Sciences, Arts and Humanities (FSSAH) Artemii Ponomarevskyi worked as an English-Ukrainian interpreter for the military in Lithuania and other locations for two years during the Ukrainian-Russian war.

Learning on the Frontlines
Unlike traditional interpreters, who often work in controlled environments, military interpreters operate in unpredictable conditions.

“Military interpreters work not only in classrooms but also in forests, on boats at sea, and in the darkness with (or sometimes without) night vision goggles. They interpret during simulated assaults while on the move, during building and basement clearing exercises in the clouds of smoke, and even occasionally under fire from blank rounds,” says Artemii.

As the job also involves rapid processing of information and ensuring that communication remains seamless in high-pressure situations, the linguistic skills of an interpreter must be flawless, including specific terminology. Especially as one of the biggest challenges in military interpreting is the vast and highly specific terminology.

“When I first started the job, I quickly realised that I needed to develop a completely different set of English skills, particularly related to military terminology and procedures,” says Artemii, a former Master’s program student of Translation and Post-Editing of Technical Texts (previously, Translation and Localisation of Technical Texts) at KTU FSSAH.

The doctoral student says that his knowledge from a terminology course in the studies proved invaluable in tackling this issue. “Using the knowledge, I was able to create well-organised glossaries on various military topics. I shared these glossaries with my colleagues, who found them highly useful while preparing for their work,” says Artemii.

Intercultural communication competence is crucial
It is often said that translation and interpreting require different skills. While translation focuses on written texts and interpreting on spoken words, Artemii’s experience proved that both disciplines share fundamental principles, especially those related to intercultural communication.

“When people from different countries speak, they represent their culture. Different worldviews can sometimes cause misunderstandings. That’s why an interpreter is not just someone who repeats messages from one language to another, but also a mediator between cultures. My studies also helped me learn how to navigate between different cultural perspectives,” says Artemii.

He says that his training in intercultural communication during the studies was instrumental in handling culture-related communication situations. Recognising cultural nuances and local context helped prevent miscommunication that could otherwise disrupt military cooperation.

Another surprising skill that came in handy was audiovisual translation. In military settings, communication can be non-verbal –whether due to language barriers or the need for discretion.

“At times, due to language barrier, a speaker would explain something vaguely, like “…take this thing and place it next to that thing…”, while using visual materials, objects, or gestures instead. In such mode, interpreting required constant visual contact, careful observation, and quickly transforming visual hints into words,” shares the KTU doctoral student of Education programme.

The human aspect of interpreting
At its core, interpreting is not just about language – it is about people. Understanding the emotions, stress, and urgency behind the words is just as important as the words themselves. Translation studies at KTU also emphasise soft skills, which proved to be just as crucial as linguistic expertise in Artemii’s work. In high-stakes situations, the ability to remain calm, professional, and culturally sensitive made all the difference.

“I found that interpreting in an international military setting was not just about conveying words but about facilitating understanding and ensuring smooth collaboration. This also applies to other translation and interpreting fields”, notes Artemii.

The Head of Study Programmes of Linguistics and Translation and a lecturer at KTU FSSAH Audronė Daubarienė says that the Faculty is proud to have had such a student as Artemii. “Despite his intensive work, Artemii graduated from his Master’s studies with flying colours. His successful professional experience confirms that the study programme of Translation and Post-editing of Technical Texts holds high standards for training translators and interpreters,” says Daubarienė. The programme is recognised by the European Commission quality label European Master’s in Translation, which was awarded to the study programme for the second time.

Starting from September 2025, FSSAH is launching an updated version of the study programme. To meet the need of students to enter the job market faster, the duration of the programme will be 1,5 years instead of two. “Blended mode of studies will allow more flexibility for students to combine studies and work. In addition to specialised translation, translation projects management and AI in translation modules, we introduced more alternative modules of translation, adding legal and medical translation and interpreting,” says Daubarienė.

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.
