From October 28 to 31, the international youth project laboratory BRICS Project Lab – Minsk was held in Minsk. It was organized by the Representative Office of Rossotrudnichestvo in the Republic of Belarus jointly with the NSO MGIMO and the Belarusian State University with the support of the A.M. Gorchakov Public Diplomacy Fund.

The laboratory brought together undergraduate and graduate students, and young scientists from Russia, Belarus, and the BRICS countries to develop practical projects aimed at advancing international cooperation. From over a thousand applications, the organizers selected approximately one hundred participants. The competition's difficulty is comparable to that of applying for a scholarship to MGIMO.

Mikhail Krikunov, a master's student at the Faculty of Information Technology and an assistant at the Department of Informatics Systems at NSU, was one of the Russian representatives among the finalists.

"I submitted my application in September, went through an interview, and received confirmation of my participation in early October. The lab isn't just a forum, but a platform where young researchers work on real projects at the request of government and international organizations," says Mikhail.

He and his teammates participated in the track "Current State of the Pharmaceutical, Medical Devices, and IT Markets in the Republic of Belarus," which was developed in partnership with the Trade Mission of the Russian Federation in Belarus. The work began online in October: the team analyzed the market, studied product certification and registration processes, and systematized data on preferences and growth opportunities in the pharmaceutical and IT sectors.

"The in-person stage in Minsk was a logical continuation of the project. We participated in consultations with experts, met with representatives of the Trade Mission and lawyers to clarify details and finalize the study. Ultimately, we prepared over a hundred pages of analytical materials, which we submitted to Yuri Vasilyevich Zolotarev, the Russian Trade Representative in Belarus. He highly praised our work and noted that the results would be forwarded to the Russian Ministry of Industry and Trade," Mikhail shares.

According to the participant, the eventful program included lectures, meetings, discussion platforms, and a cultural component: students visited the Russian Embassy in Belarus, the Court of the Eurasian Economic Union, the Minsk City Technopark, and saw the city's landmarks.

"I'm happy to have seen the heroic city of Minsk, to have contributed to strengthening trade relations between Russia and Belarus, to have met a huge number of smart and kind people, professionals in their fields, ready to move forward no matter what, and to have made friends in my teammates. I hope this project lab will become a starting point for our team's future work on other projects," Mikhail concludes.

In the near future, the team plans to continue the research in the form of a scientific paper and publish its results.

On November 8, the "Voices of Siberia" concert took place in the auditorium building of Novosibirsk State University. It was a large-scale choral event that brought together 11 groups and ensembles from six Siberian cities. The concert was part of the annual "Music Unites" music festival, of which NSU was the general partner in Novosibirsk this year.

The festival featured ensembles from Omsk, Tomsk, Krasnoyarsk, Kemerovo, Gorno-Altaysk, and Novosibirsk—a total of more than 300 performers. Among the participants were the NSU Academic Choir, the Blagovest Youth Choir, the Y.A. Braginsky Academic Choir of the Novosibirsk State Technical University, the Carpe Diem Choir (Kemerovo), the D. Hvorostovsky Saratov State Institute of Arts Choir (Krasnoyarsk), the Tomsk State University Choir (Tomsk), the E. Denisov Tomsk College of Music Mixed Choir, the SFU Academic Choir, the Bel Canto Youth Choir (Omsk), the NSPU MO Mixed Choir, and the Viva Voce Choir.

Each group presented its main work, and in the finale, all participants performed together for the first time the closing number of the festival oratorio "Faces of Siberia"—a work by Novosibirsk composer and member of the Union of Composers of Russia, Oksana Serebrova, which has become a symbol of unity and community among all Siberian cities participating in the project.

The project's director, NSU graduate Anton Niyazov, addressed the audience and participants with a welcoming speech:

"Today, November 8th, we're opening the gala event "Music Unites" in Novosibirsk. The festival is all about bringing together not only amateur and professional musicians, but also programs of diverse natures and genres, as well as different venues. Today's venue is, in a sense, remarkable: it's the enormous new auditorium building at NSU, which is likely the first time it's hosting such a large-scale concert. It's crucial that our program be uninterrupted and without words between pieces, so as not to disturb the atmosphere of collective meditation."

Olga Yakovleva, Vice-Rector for Youth Policy and Educational Work at NSU and PhD in Philology, noted the high level of performance by the NSU University Choir and the importance of such events for the university community:

"I am pleased that our choir performs at a high level, and that, compared to professional choirs at other universities with music departments, our university, where musical activities are conducted only extracurricularly, looks respectable."

Such events are important for our academic choir: the students often participate in competitions and festivals, but sometimes it's important to host events on our own site. NSU traditionally brings the city together for scientific and educational events, and now, thanks to our new infrastructure, we can host cultural and creative events and invite Akademgorodok residents and visitors.

Elena Krasilova, Head of the Department of Youth Policy and Educational Work at NSU, emphasized that the annual festival is developing and expanding its geographic reach:

"The festival is constantly evolving—it's been growing and developing for several years now. It began as a project of Novosibirsk choral groups, but has now expanded beyond the region. It's gratifying that leading choirs from Siberian universities are participating, including Tomsk State University and the Siberian Federal University."

Members of the NSU Academic Choir—Nelly Khrapova, Nikita Afimchenko, and Lilia Minushkina—shared their impressions and highlights of the performance.

Nelly: "This concert is different from others because we were placed in unusual circumstances—we stood opposite each other and heard every number from the other bands. Usually we're backstage, but here we were face to face—it was an unusual and joyful experience."

Nikita: "What was also unusual was that everything happened so quickly—we had little time to prepare. But it seems like everything worked out."

Liliya: "It's also worth noting that this was our first time performing in the auditorium building. The acoustics here are exceptional—the sound 'flies,' it feels like you're in a church. The a cappella pieces sounded simply wonderful today, in my opinion."

Speaking about working with other groups, the choir members emphasized that the collaboration required attentiveness and flexibility:

Nelly: "Adapting is always difficult; every conductor has their own approach and vision. But the oratorio we'll be performing tomorrow has one common conductor, who helps bring everything into a unified sound. When we begin to understand each other and speak the same language, the work flows easily."

Liliya Minushkina shared her favorite moments of the program: "My favorite moments are the a cappella numbers. They're a real challenge for any choir. You have to be extremely attentive and listen to each other."

Nikita Afimchenko noted the scale of the project: "Events like this don't happen often, and they require serious preparation. We're really looking forward to tomorrow's concert, where many groups will unite and work as a single entity. It's challenging, but very inspiring."

The "Voices of Siberia" concert was more than just a festival performance, but also a gathering of like-minded individuals for whom music is the language of mutual understanding and collaboration. Siberian choirs united at NSU to prove that creativity truly can unite cities, universities, and generations.

An important disclaimer is at the bottom of this article.

Novosibirsk, November 10, 2025: Analytical Center "Expert" published the results of the eighth wave of the study of universities leading in training technology entrepreneurs. Novosibirsk State University was the only university from the region to make it into the top ten. Leading Moscow universities also made the top ten: HSE, MIPT, Lomonosov Moscow State University, Bauman Moscow State Technical University, and RANEPA.

The ranking is based on a database of approximately 3,000 startups and 3,500 of their founders. The 2025 ranking assessed universities using a scoring scale that took into account graduates' performance in creating both local and international startups. In 2025, the database of local startups (headquartered in Russia) founded since 2015 reached 859 companies. These projects were founded by 1,103 entrepreneurs representing 280 Russian universities. The database of international startups was compiled using Crunchbase and includes 2,078 companies and 2,357 entrepreneurs.

"NSU's development strategy envisages a transition to a scientific and technological university model by 2036, where technology will be the core business alongside education and research. With this in mind, we are paying special attention to developing student technological entrepreneurship. We are building an effective support ecosystem at the university—from the inception of an idea to its development into a mature business. NSU has a Startup Studio, the .catalyst acceleration program, a campus course on technological entrepreneurship, and a practice of defending final theses in a startup-as-a-diploma format. This year, we were among the winners of a federal competition for the development of university startup studios, which will expand our capabilities in this area," commented NSU Rector and RAS Academician Mikhail Fedoruk.

The infrastructure created at NSU to foster technological entrepreneurship has its own unique characteristics. The university is located in Akademgorodok, a district of the city near more than 30 institutes, as well as one of the country's leading technology parks, home to high-tech companies. NSU is primarily focused on training researchers, so most student startups are based on scientific research, and students have the opportunity to develop these research projects into products. The unique ecosystem of the Novosibirsk Scientific Center allows for a more rapid transition from concept to market launch.

"This environment gives students a real opportunity to launch their own technology products and services while still studying, gain practical experience in development, interacting with clients, and become familiar with the fundamentals of business management—from accounting to legal aspects. Over the past three and a half years, more than 1,130 people, including students not only from NSU but also from other Novosibirsk universities, have completed training in our .catalyst acceleration program. 67 residents of the NSU Startup Studio won the Student Startup competition and received grants of 1 million rubles each to implement their business projects. Furthermore, more than 30 teams have become residents of the Akadempark business incubator," said Alexey Starostin, Director of the NSU Center for Entrepreneurial Initiatives.

Thus, having gained experience developing their own project while still studying, students become specialists who not only possess basic professional knowledge but also understand the technology stack, legal issues, team selection and management, and development promotion. Such creators are now in demand in any field.

NSU scientists have discovered bipolar conductivity in non-stoichiometric germanosilicate glass films for the first time.

Gaysaa Hamud, a postgraduate student at NSU and a research assistant at the Laboratory of Functional Diagnostics of Low-Dimensional Structures for Nanoelectronics at the Analytical and Technological Research Center "High Technologies and Nanostructured Materials" of the NSU Faculty of Physics, was awarded a diploma for the best oral presentation, "Study of the Conductivity Type of Films of Non-Silicate Germano-Silicate Glasses," at the 16th Valiev International Conference "Micro- and Nanoelectronics – 2025," held from October 6 to 10 in Yaroslavl. The young researcher, who is also a research engineer at the A.V. Rzhanov Institute of Semiconductor Physics of the Siberian Branch of the Russian Academy of Sciences, presented her paper in the "Materials for Optoelectronic Devices" section. For Gaysaa Hamoud, this presentation was her first oral presentation at an adult conference; previously, she had successfully participated only in student and youth conferences.

“We were the first to study the type of conductivity in germanosilicate glasses. This is the novelty of my research. This knowledge is important for understanding the conductivity mechanism in these nonideal dielectrics (in which so-called leakage currents are significant). In any materials – both semiconductors and dielectrics – there is a different type of conductivity: either electronic type, or hole, or bipolar. To improve the performance of devices that use a particular dielectric, it is important to know what type of conductivity is characteristic of it. The object of study in my research was germanosilicate glasses, which can be used for the manufacture of photosensitive MIS structures (metal-insulator-semiconductor structures). Previously, we obtained in them the effect of very good photosensitivity, which is important in their application for technical vision, light-sensitive sensors and memristors, and decided to explain the mechanism of its occurrence. The fact is that germanosilicate glasses are not an ideal dielectric; they conduct electric current. We take advantage of the non-ideal nature of germanosilicate glass (leakage currents) to achieve the beneficial properties of MIS structures based on them. For example, in MIS structures such dielectrics suppress the dark current, but do not greatly weaken the photocurrent. This leads to an improvement in their photosensitivity. And, perhaps, devices based on such dielectrics will replace more expensive industrial photosensitive devices. It is possible that such new materials and devices will be inexpensive, small in size, and consume little energy. However, in order to improve photosensitivity, it is necessary to establish the mechanism of photocurrent generation and the type of conductivity, said Gaisaa Hamoud.

The young researcher began studying the properties of germanosilicate glasses at the very beginning of her graduate studies about three years ago, under the supervision of Vladimir Volodin, a leading researcher at the Laboratory of Functional Diagnostics of Low-Dimensional Structures for Nanoelectronics, Department of the Analytical and Thermal Analysis Center, Faculty of Physics, NSU, a leading researcher at the A.V. Rzhanov Institute of Semiconductor Physics, Siberian Branch of the Russian Academy of Sciences, a professor in the Department of General Physics, and Doctor of Physical and Mathematical Sciences. It took about a year to study the conductivity type in these structures.

Routine semiconductor methods such as the Hall effect, thermal probes, or dielectric charge relaxation are not applicable in this case for a number of reasons. Therefore, the scientists used the classical nonequilibrium depletion method by injecting minority charge carriers from the substrate into the dielectric in a metal-insulator semiconductor (MIS) structure. This method studies the current-voltage (I-V) and capacitance-voltage (C-V) characteristics of samples in the dark and under illumination. The study covered four sample compositions grown on different silicon substrates—n-type with n-type conductivity and p-type with p-type conductivity. A total of eight samples were examined. The authors varied the ratio of germanium oxide to silicon oxide in the films. They noted that silicon oxide has been well studied to date, while germanium oxide remains poorly understood, and a mixture of the two has not been studied at all.

Using the nonequilibrium depletion method with minority carrier injection, we can inject carriers of different charges—both negative and positive—into a dielectric. These are either electrons or holes. We can then observe whether they pass through our dielectric. The essence of this method lies in the controllability of the injection process. It is considered a classic, and researchers have been using it for over 40 years. One of the method's authors is Professor Vladimir Alekseevich Gritsenko of the Institute of Semiconductor Physics SB RAS. Using this method, we discovered that germanosilicate glasses have bipolar conductivity, which can involve both electrons and holes. We then refined this method by analyzing photo-EMF (the electromotive force that occurs in semiconductors when exposed to light). We noticed that no EMF occurs in a dark MIS structure without applying an external voltage. However, when exposed to light, electron-hole pairs are generated in the silicon substrate, which are then separated by the built-in field, generating a photo-EMF. Solar cells operate on the same principle: we expose p-n junction silicon to light, and electron-hole pairs are generated in the sample, which are separated by the field built into the p-n junction. If we short-circuit a light-illuminated MIS structure to a payload, the light energy is converted into electrical energy, explained Vladimir Volodin.

The MIS structures studied, based on germanosilicate glass films, can also be used as solar cells, but this was not the goal of the study, so the scientists did not optimize the relevant parameters. For this reason, their efficiency as solar cells does not exceed 0.01%, while 10% is required. Therefore, using them for this purpose is impractical, but that was not the researchers' intended purpose.

MIS structures based on germanosilicate films were studied in the dark and with illumination. Subsequently, by analyzing the nonequilibrium depletion during minority carrier injection from the substrates, the scientists concluded that germanosilicate glass films of various compositions exhibit bipolar conductivity. These findings were confirmed by analyzing the sign of the photo-EMF generated in the MIS structures under illumination.

It was important to confirm the results obtained from studying the current-voltage and capacitance-voltage characteristics. For this, we used an approach based on photo-EMF analysis. In our structures, even without applying an external voltage, but only under the influence of light, we observed depletion with band bending of approximately 0.5 volts in both substrate types. In our opinion, photo-EMF should not occur in the case of purely hole conductivity in an n-type silicon substrate, because holes do not accumulate in them but pass through the dielectric. However, if the resulting voltage reached the flat-band voltage (0.5 volts), this would indicate the presence of only n-type conductivity. However, when photo-EMF occurs that does not reach the flat-band voltage, both n-type and hole conductivity are present. We found that this effect is observed in all our samples when the photo-EMF is lower than the flat-band voltages for n-type and p-type silicon. Simply put, if the photo-EMF is zero, one type of conductivity is present, depending on the substrate; if the photo-EMF reaches its maximum values, another type is present. At intermediate photo-EMF values, both types of conductivity are present simultaneously, said Gaysaa Hamoud.

This fact further confirms that germanosilicate glass exhibits bipolar conductivity. In the future, the scientists intend to focus on improving the photosensitivity of the MIS structures they are studying. The results of this research will be applied in the creation of photodetectors based on MIS structures without a p-n junction. Currently, commercially available photosensitive devices operate using a p-n junction, but photosensitive devices without this junction will be less expensive and easier to manufacture.

A short tour not only offers an opportunity to explore unique experimental facilities but also to choose a future direction for study and work. Prospective students from School No. 119 visited the birthplace of future aviation and space technologies. They were shown the T-325 supersonic wind tunnel. This technology is the basis for fundamental research, including studies on turbulence control and fuel economy. As one of the staff members noted, if the problem of airflow turbulence on a wing were solved, an airplane could fly not from Novosibirsk to Sochi, but, for example, to New York on the same amount of kerosene. Such experiments are not only available to experienced scientists. Many physics students conduct their own experiments using it during their studies.

The applied aspects of the institute's work were also highlighted. Tour participants learned about the complex technologies used to produce and restore turbine blades for aircraft engines—components that only four countries in the world can produce. Such large-scale research sparks a keen interest in the students.

"I like physics. I'd like to conduct some kind of experiments, it's so interesting!" shared Anna Zhuravleva, an 8th-grade student at School No. 119.

The children were particularly interested in the T-313 wind tunnel, where experiments last only a few minutes but are effective for science.

ITAM SB RAS conducts excursions infrequently, about eight times a year. The primary audience is schoolchildren and students majoring in physics. Sometimes, such excursions are held as part of various popular science events, such as Physfest, Smartpicnic, and Science 0. According to the institute's staff, such events primarily serve to popularize science in general. Their goal is to help schoolchildren learn new things, including mechanics in its various forms.

According to the institute's staff, NSU students begin working in unique wind tunnels as early as their third year, completing coursework and graduation projects. Many of them continue their research in master's and doctoral programs.

The Institute of Theoretical and Applied Mechanics is a place where education and science come together. Students receive not only theoretical training but also the opportunity to immediately apply their knowledge in practice, working with world-class equipment to address pressing aerospace challenges. Graduates who complete this program become highly qualified engineers and scientists, in demand at leading research centers and industrial enterprises across the country.

And the challenges are real! An off-site immersion for NSU students

Translation. Region: Russian Federation –

"Labyrinth"—a laboratory for intensive intellectual development—is the name of the 2025 on-site mathematical immersion program for first- to fourth-year students in research groups. Faculty of Mechanics and Mathematics of Novosibirsk State University— a regular event of the Sobolev Institute of Mathematics of the Siberian Branch of the Russian Academy of Sciences with the support of the International Mathematical Center. The immersion took place in late October at the O. Koshevoy health and educational camp. Nearly two dozen students passionate about mathematics solved problems, participated in creative competitions and a conference, watched films, and attended lectures.

Only four problems were assigned over the two days, equal to the number of teams. But, as usual, most of them had no clear answer, requiring careful thought to come up with an engaging solution, which each team presented at the final conference. The problem conditions can be considered a framework. Teams can refine them, change them, narrow or expand them to present a general, attractive solution. For example, the question, "Into how many squares can a 7 by 5 rectangle be divided?" quickly evolved into a search for the minimum number of squares, since everyone knows the multiplication table. The goal was to find some universal formula for dividing the squares. Many teams quickly arrived at Euclidean division with remainder, but no one came up with a hypothesis for the minimum number of squares.

The second problem required fitting the maximum number of fragments with four vertices into a graph. The most successful graph was one in which edges were drawn between all vertices, and then many more edges ("fuzzies") were added to each vertex. Lev Zhukov and Timofey Vasiliev drew attractive, "fluffy" graphs.

The third problem, at first glance, seemed simple enough. What strategy should you follow when erasing one fragment at a time in a chain so that after your move you don't end up with two segments with the same number of links, while your opponent does? A clear algorithm for a sure victory was not found. The question remained open.

"Do you know the solution to this problem?" the students asked.

"Of course not!" the organizers admitted frankly. They weren't being disingenuous. Solving problems with predetermined answers, like a test in school, is a bit boring for real researchers, whether they're in their first or fourth year. The students laughed, of course, but they were pleased to be on equal terms with doctors and candidates of science. Many of their eyes lit up: "These are real problems!"

Klim Bagryantsev offered a beautiful and colorful image (but not a solution) of a problem where one had to divide a rectangle into four pieces of a "triomino" game. This is a well-known type of problem involving filling a surface with identical fragments. The result is a fractal canvas of four colors, similar to a Sierpinski triangle, where small shapes compose similar larger ones.

Each team had its own name and mascot. The name "Outegral" clearly aspired to a new concept, the opposite of "integral." The "Nail Rinatovich" team was named after a classmate who was absent from the team and whom the students clearly missed greatly. The "Koala" team's full name was "Koala Eucalyptus," and the "Mathematini" team's mascot was a true artistic masterpiece, adorning the event until its departure.

"This year's immersion was a very emotional experience for me," said fourth-year student Daria Koroleva. "I'm so glad the first-year students managed to keep their cool and solve the problems. It was a lot of fun with them. I really enjoyed the problems. I was a little disappointed that I couldn't find a perfect solution, but that's not always possible, but solving them was a lot of fun. You get completely immersed in the research process, generating hypotheses, considering different examples, proving or finding counterexamples, communicating, and discussing ideas. Researching problems with other students is a unique experience."

In addition to math problems, there were night photography contests for the most geometric and the scariest shadow. Some scenarios required participants to perform complex choreography and even some acrobatic skills, while others required only a little mischief and ingenuity.

The country camp became a magnet not only for students and teachers—the first lecture, dedicated to mathematical billiards and Birkhoff's algebraic conjecture, was given by Andrei Mironov, Director of the Sobolev Institute of Mathematics, Siberian Branch of the Russian Academy of Sciences, and Corresponding Member of the Russian Academy of Sciences.

There are a huge number of very beautiful theorems concerning Birkhoff billiards, and many still unproven conjectures. For example, the question of the periodic trajectory of a billiard ball within any convex figure. In an acute triangle, it will be periodic, meaning the ball will repeatedly hit the same points. But within a circle, there can be various periodic trajectories of a billiard ball—from an equilateral triangle to a square, a five- or even a six-pointed star. Andrei Mironov gave students a brief history of scientific research into Birkhoff's conjecture and presented several solutions, authored byoneof which in 2019 was the lecturer himself, together with a colleague from Tel Aviv University, Professor Mikhail Bial.

Birkhoff's conjecture states that every integrable billiard table is an ellipse. An elliptical curve that touches all segments of the billiard ball's trajectory, bending around them, is called a caustic. This term came to mathematics from optics, where it described the geometry of reflection and refraction of light beams such that in certain places the light gathers into particularly bright spots, for example, on the surface of the sea or inside a faceted diamond. A question from the audience asked whether caustics can intersect. The speaker replied that no one had yet solved this mystery.

Andrei Mironov spoke about his acquaintance with Mikhail Byaly at a conference in Scotland, and the organizers of the mathematical immersion recalled that a team of schoolchildren from Scotland (including children of NSU graduates) once won their annual autumn math marathon. The bizarre and vibrant, caustic intersections of scientific trajectories demonstrate that mathematics is not self-sufficient and cannot develop in a hermetically sealed manner within a single country, city, or institute. Mathematics is one. People living on opposite sides of the globe simultaneously ponder the same problems and ask the same questions.
