it is clear that thyme stands out from mint in our country, how are things going in new regions of the country? what environmental problems we have, we need to fight them. and did anti-russian sanctions affect the activities of russian scientists? a small town with a population of 100,000 people, in the lugansk region, about 200 km by car to rostov-on-don, and about 40 to the capital of the lpr. alchevsk is considered the rear of donbass, the front line passed although nearby, there were battles for neighboring artyomovsk, but still on the side , however, without shelling from the side.

ukraine was not spared here either. this year , the city has been featured in nwo news reports several times. with the advent of new weapons in ukraine and the range of missiles, accordingly, we came under fire and found ourselves in red territory. valeria fedorova has been living in alchevsk for several years, since she moved here after her husband, an employee of the local metallurgical plant. and she herself heads the department of ecology and safety at the donbass technical state university, gives lectures to students and conducts scientific activities, this is probably where i stay, where i like, where my development will probably be and i can bring something that may help something in the future in life. she has a successful postgraduate defense under her belt.

i had a topic on the pharmacodynamic effectiveness of use in a model of closed traumatic brain injury. work in two universities of the lugansk people's republic and many implemented scientific projects, almost all of them are related to the protection and restoration of nature , we have environmental problems , we need to fight them, we need our nature support, help. to recover, since she does not know how to do this at the moment. currently, valeria is breeding sturgeon, which she calls hydrobionts; the fish are kept in a closed cycle system, that is , in a specially equipped pool in one of the laboratories of her university. we create comfortable conditions for existence and development, for their full development.

such a project did not arise spontaneously; as an ecologist, she believes that biodiversity is so disturbed that it requires not only emergency measures to clean up the environment , but also a systematic search for solutions on how to effectively replenish lost resources, the discharge of industrial wastewater, yes, the same fish hatching - in industrial volumes in general, which our water bodies have just become impoverished. there are few fish there, the diversity, let’s say, has decreased, and i probably wanted to help our nature, with something significant, so that it would really have some positive impact, her scientific project explains valeria, is aimed at a number of important tasks , using the example of setrovids, which are considered:

extremely sensitive to the environment, the university is developing methods for restoring and maintaining water quality; their research , scientists say, can also be useful for those who want to run their own fisheries. in principle, anyone can install the same pool in their own private home with the entire cleaning, aeration, filtration system and use an environmentally friendly product, please, for themselves... even at home. during the ukrainian attacks on alchevsk, valeria recalls, not only people suffered, but also her pets. university employees transferred to remote work, but the fish require daily care, in the conditions of a special military operation, it turned out to be a difficult task, she says modestly, and her mother tells the details. when yarilera, people die, and you for your fish , she’s mom, what are you saying, this is our job, i... i can’t, and her

employee says, ulga dmitrievna, and you know that when it was hot, she was at home, i brought bottles of water with my husband in the car, lowered them into the pool, cooled the water in such a way that the fish did not die, so i i admire my daughter, ulga dmitrievna, and she herself is worthy of admiration, she is the chief doctor of the clinical oncology dispensary of the lugansk people's republic, hello, hello, sunshine, hello, how i love you, i miss you very, very much, i miss you as a candidate of medical sciences, an operating surgeon, following the example of her mother, valeria dreamed of treating people since childhood, but due to circumstances she chose a different profession, there was probably only one big problem, the sight of blood

made me feel bad, well, such feelings, very, very negative, i entered medical school university, but not at... the medical faculty, but the pharmaceutical faculty, then graduate school and the unknown events in the donbass, these are some problems that were, yes, turned out to be so insignificant, so completely insignificant and yet you understand that the happiness of waking up in the morning to see your loved ones nearby, this is probably the most important thing in life. last december , valeria fedorova was invited to the congress of young scientists, which was held in sochi; vladimir putin met with the participants of the congress ; she asked the russian president about the possibility grant support for science in donbass.

there was such a question, since our territories, naturally, were deprived of such support , after the congress before the bill, our universities can now also participate in grant support, and we are already planning, or rather, we even have results, we have already received grants, students, now, in in general, in her city, alchevsk, in lugansk, things have become better, valeria believes, many things are being restored, rebuilt, and she herself continues her teaching scientific work. within the russian federation, of course, it seems to me, more prospects, we have more , these are the opportunities that we can bring to life, i hope everything will work out, we, alexander

and dmitry koshnin, i calculated a model of a super-hard material for industry, and i calculated a model for a super-sensitive gas analyzer. and this is grandfather, thanks to his ingenuity, we became interested in science. develop an interest in science from childhood. alexander and dmitry gemini, they were born in krasnoyarsk, into a family of physicists, and as they joke, their professional paths were predetermined historically. grandma nina vasilievna, she was the first graduate student of leonid vasilyevich kirensky, the founder of the krasnoyarsk school of physics and grandfather. he was a physics teacher, the director of the lyceum, it was from his grandfather, in fact, this came from him, he tried to instill a love for physics, as well as his father, mother and her sister, all devoted themselves to science, the brothers remember that there was an appropriate atmosphere in the house,

the names of nobel laureates were heard, discoveries were discussed, articles were being prepared for publication, however, their own passion for physics did not appear immediately. well, no one likes to study, for some reason, in fact , only later do you realize that it is actually useful, and when you reach some limit and think, you want to learn something new and so on, but then no , i didn’t want to do anything at all, but my grandfather didn’t give up, he regularly worked with his grandchildren, explained to them complex natural scientific laws, interpreted certain experiments, and most importantly, alexander says, he taught them to think in images, to see meaning behind dry numbers and the strict logic of life formulas, that is for i took an ordinary person, turned on the light, yes, well, that’s it, the light came on , okay, what should i do about it, and if i think about it, i look at him, he turns on the light, i understand that when you turn on the light, it means the circuit is closed, the field goes this way, electrons run here, heats up, radiates, you understand

why this happens, this, in principle, from my point of view, is the most important thing in science in general, after school, the kvashnin brothers entered the krasnoyarsk state, now siberian federal university, to study physics faculty, and have already completed the master's course at the moscow institute of physics and technology, one of the strongest universities in russia, according to the international ranking of times high education, dmitry alexander graduated with honors, i have samples of not only the structures, but also the materials that we synthesize, in particular, in this flask there is a powder, this black one, this this is precisely the highest tungsten barite that we predicted and now we know how to synthesize it in the form of such a nanometer powder. top scientific journals and daily newspapers published this news several years ago. skoltech employees, including alexander kvashnin, current professor. institute of science and technology managed to decipher the crystal structure of superhard

tungsten baride, a task that the world's leading laboratories have been trying unsuccessfully to solve for decades. this is the model of the highest boride wolfran that he predicted. this material first attracted attention in the middle of the last century. its mechanical properties were of great interest to scientists. here is an example of what we have already explored. it’s hard, we can say that it’s half as hard as diamond, it sounds this is so-so, but nevertheless it is harder than other materials that we know, previously it was believed that the basis of this chemical compound was four boron atoms one tungsten atom, but in reality the theoretical models and experimental descriptions differed greatly from each other, explain this phenomenon turned out to be within the power of russian specialists, and now... there are many different algorithms for searching for crystal structures on a computer.

accordingly, we also have some kind of intuition, chemical, physical, we we thought, let’s study this compound, the tungsten and boron systems, and let’s predict on the computer all the stable compounds that may have different compositions. research has shown that tetrabaride does not exist at all, and what was assumed to be a crystalline structure for the previous 60 years. only one of the variations of pentaboride, that is, in reality, for each tungsten atom there are not four, but about five boron atoms, the black ones painted by hand are tungsten atoms, the white ones are boron atoms, the blue ones are also boron atoms, which are located in special positions, due to which the structure becomes very strong. now that, thanks to alexander kvoshnin and his colleagues, the exact formula is known, it has become

possible to obtain any, even the most minute, volumes of the finished substance. the potential scope of application is the widest from spare parts for cars, to use in professional equipment, for example, as part of drilling rigs, in fact, from the search for super-strong material for industry and detailed studies began, which eventually led their team to an important scientific discovery. here we have a drill bit with which we drill the earth, but not us, people drill the earth to extract oil, gas and so on, there are cutters that do everything this thing is being drilled, and these cutters consist of a hard substrate on top; a diamond is melted on top, everything is drilled with these diamonds, but the task was to replace the diamond with something else, something cheaper, traditionally used as a hard substrate... the winner is used , well-known and widely used in many alloy industries we're talking about winning. will win

- what is it? here we have tungsten, we combine it with carbon, we get tungsten carbite, very hard, and then we add a binder in the form of cobalt, and we get a winner. in addition to the mining and manufacturing industries, it will win; we also know this material for tank armor. the material is resistant to cracks, explains alexander, very dense, durable, weighty, such a small fragment pulls 8 kg, scientists have proposed to use this base from the victorious add tungsten barite as a low-cost alternative to diamond. and experimentally , another layer of tungsten boride was baked on top to create a cutter like this, which can be used for drilling various rocks. now alexander continues his research in the field of borides. another area of ​​his activity is high temperature. one of the most technically complex areas of modern material ; he also

teaches and lectures to students, like his brother gemini. to the family of dmitry kvyshnin happiness recently came, a child was born, and now he spends all his free time with the baby. another one. a few years earlier, he completed another important life’s work, receiving the degree of doctor of physics and mathematics. the defense of the dissertation coincided with the coronavirus pandemic. which caused a lot of anxiety for the applicant, i was told that only i had to come to the defense, no spectators, no fans there, you can’t bring your family, as usual, opponents, there are six of them here, they were online, twice because of the pandemic the defense endured, so, but nothing, in the end it happened later, this is what happened on july 2

, 2020, dmitry kvashnin has been studying the properties of graphene-based nanostructures for many years, such... the scientist explains the choice by the prospects of such research, that is, nanomaterials are many times larger sensitive, if not in order, may be sensitive standard materials used, and this allows you to see what standard current materials cannot see now, i’m talking about medicine, with the help of modern computational methods it explores and offers new materials that, due to their characteristics, can be useful to many people, dmitry theorist. fundamentalist, so his main activity is related to working on a computer, in fact, why is the field of quantum chemistry needed , now artificial intelligence and machine learning are attached to it, so as not to do a huge number of experiments, but to tell in advance on the computer what can work and what cannot may already pay attention to specific

conditions, for example, he has calculated and predicted the possible synthesis of boron oxynetride, a new material or... whose properties can be controlled, the first samples were obtained several years ago, and further research only confirms the promise of the find, professors in china, they continue to synthesize this material and use it for the detection and therapy of oncological diseases , now they are doing a study on mice, where they showed that nanoparticles of this hydroxy 3 addition, they have a positive effect on, well, it’s correct to say, they have an effect on slowing down the growth rate of tumors in mice, that is, somewhere there it is clear that it slows down by 70%, his support is a support in everything, including big science, his wife sophia, they studied at the same university in krasnoyarsk, began to communicate and be friends in their student years,

i fell ill with pneumonia, and i was in the hospital for a whole month, i come, but it’s already a third of the semester , i come to the teachers and tell them, i don’t know anything, how can i make it in time, how can i understand all this, well, that is, from scratch. i needed to catch up somehow, and some teacher said: here you go, here you go help, help her, help her everything, well, in short, and that’s how we got together, now they both work at the institute of biochemical physics of the russian academy of sciences, but sophia received a second education, linguistics, and now she deals exclusively with translations, but i help researchers, with articles, when they have to submit articles to foreign journals, it’s in english, well, they kind of write as best they can, and i proofread. dmitry and sophia traveled halfway around the world together, on this symbolic map there are marks where they visited, sometimes on vacation, but more often at scientific conferences, however, now the geography has changed somewhat against the backdrop

of the sanctioned isolation of russian science. the first feeling was very noticeable. this is the absence of foreign business trips, conferences, that is, it is possible to get there, but the question is at what cost , and the question becomes, why, our main cooperation with china now is within the framework of the russian science foundation project, which we submitted, so, if i hope, the project will pass , then we will cooperate with them more actively on specific tasks that we wrote. so, well, how are we? things are going well, great, uh-huh, then now you are preparing the solvents, yes, yes, we are weighing, great, yes, and here we have it, guys, in this laboratory

of st. petersburg state university there are very important, albeit invisible , unarmed. which are vitally important for each of us, what kind of juice is today, apple from kiwi, and orange too, uh -huh, great, good, kirill, what is your task today , irina timofeeva, candidate of chemical sciences, is leading the research, i directly want to determine today in feed or in milk, antibiotics, we’ll have to first soon, yeah, well, we’ve already prepared the milk well, great, good, then we get to work, together with the students, they determine the quality and check: the safety of baby food, food products, juices, water, in a word, everything that is included in the daily diet of humans or animals, there was a lot

of ascorbic acid in this sample, yeah, yeah, yeah, you can see from the values, yes, they are also developing methods and systems of rapid tests with the help of which like could the analysis be carried out at home, at home or right in the store? i then omit the strips, here they are with for example, to establish the content of vitamins in the composition of the liquid, so, well, even if you turned away from me the inscription, yes, that this is a zasok, you could safely say that since it turns blue faster here, then here for sure orange , and some kind of citrus juice, yes, here the most ascorbic acid is obtained, there is a little stripe here, well, there is also, yes there is also, mints is necessary for the human body, however in large dosages, irina explains, it can cause harm to health, so it is important that manufacturers strictly follow the recommendations of the ministry of health, especially in

the food recipe for the little ones, maybe purees, there are some mixtures, complementary foods in those that need to be determined for ascorbic acid , because as you know, despite the fact that ascorbic acid seems to be a very useful component, in high concentrations it can cause allergies. in children. over the past few years, she, along with her colleague andrey shishov, has created more than sixty different methods for chemical analysis of samples, many of which are used in practice. our task is to develop such a methodology, that is, an algorithm of actions, yes, in order to determine a specific analyte, that is , a substance that we want to determine, be it a pesticide or an antibiotic or a heavy metal. in a specific object of analysis. their methods can be used to study the composition of almost anything, from food or water to oil. and building materials. to put it

simply, for example, we need to determine antibiotics in milk. this is the task at hand , we are developing methods that make it possible to isolate these antibiotics from milk in the future, to analyze this extract in order to determine which specific ones. for their scientific developments, irina timofeeva and andrey shishov were awarded the russian presidential prize for young scientists in february 2023. we were given a specific task: we are building houses, there is a smell of smoke in the new houses, please let's decide it smells bad, yes, but there are things that do not smell of anything and are not perceived by humans in any way, they are harmful materials for health, therefore, in this sense... if new opportunities arise for the study of materials, food products, then of course, it is necessary to introduce new standards, and then, accordingly, new methods that would allow these standards

to be ensured. yes, in my hands are probably the most dear medal to my heart, and the award, and this badge was presented personally by the president of our country, and my colleague, with whom we received this together... he has exactly the same time, has a badge, different numbers, before irina, there were no scientists in their family, dad was an engineer, mom was a doctor, she herself also wanted to go into medicine , but in high school she became so interested in the natural sciences that this ultimately determined not only her diploma specialty, but also her future path, analytical chemistry. i also studied in this building, and my classes took place here, too. the first one is perhaps the largest audience in our institute of chemistry, and of course, such

an environment, she could not help but contribute to becoming fascinated by this beautiful science, after receiving higher education she entered graduate school, and during her studies... she solved an incredibly complex practical problem. in 2010, residents of new buildings complained en masse about the smell of ammonia in their homes. in some apartments the smell was so strong, irina recalls, that it was physically impossible to be there. corrodes the eyes, mucous membranes, and even the nose. and for a long time being in such premises can not only cause allergic reactions, but also oncology, so of course this problem was very important and so

they turned to us, and we decided to eradicate this problem at the root. determination of ammonia precursors in concrete and concrete mixtures was the topic of her dissertation. with her scientific supervisors, there were two of them, she traveled to construction sites, took samples of fresh concrete and carried out many analyzes in the laboratory and directly on the site. two methods have been developed that are still in demand, with the help of which... analysis is carried out directly on construction sites to determine whether a given concrete mixture is of high quality or not, but specifically for a specific group of substances that ultimately produce ammonia. studies have shown that the cause of the dangerous smell in houses was urea, which was used as a cheap frost-resistant additive during construction in the winter season. unfortunately, not all points and factors were taken into account and thus

highness. this component in the sample, it resulted in the release of ammonia, that is, a urea molecule, resulting in two ammonia molecules and thus the room becoming uninhabitable. the results of the dissertation are now taken into account during the construction of buildings and residential buildings, using the methods proposed by her, the quality of materials is determined before the start of work in order to prevent violations. realizing what can really be done. something very significant and necessary first of all, yes, ah, i decided to stay in science and continue - activity, but the only thing that, you see, took me a little away from concrete mixtures towards food products, in addition to the main scientific activity, irina timofeeva gives lectures on analytical chemistry and practices for students, newbies came to the laboratory, which means what kind of weed do we have? timyan, what about

this? what does it look like? for mint, great, but what stands out from our thyme from mint? if you mix these ingredients in one test tube and shake vigorously, then after a while they will turn at room temperature into liquid that the students observed during this experiment. little by little look at what happens to these substances, they begin... to fuse, which means that hydrogen bonds are formed between thymol and menthol, that is, one acts as a donor of hydrogen bonds, the other as an acceptor of hydrogen bonds, and a new substance is formed, which we call deep solvents, and deep phtectic solvent, in addition to her leading activities, irina timofeeva regularly participates in professional conferences,

so i recently returned from kuala, where i talked about the success of russian scientists. this is a large large conference, which was attended by both european countries and asian countries, and at this conference, we from the scientific group did not feel any kind of, let’s say, social isolation, on the contrary, at the final evening we were asked to sing a song on in russian, which for us was, at least difficult, but doable. in the same year, in addition to the prize for actively working on your research, so that, like others, young scientists, after some time , present new results and discoveries to society.

footage from the gas sector after the start of the truce; the first tanker with fuel arrives through the rafak checkpoint during the entire conflict. palestinians are returning to their homes in the north of the enclave, as will israel, which has repeatedly called for the gazas not to come to the north. fsb operation, a russian was detained who was sending spare parts for military aircraft to ukraine for money. a case was initiated under the state article. treason, no lost a single game, russian alexey grebnev became the world chess champion among boys under 18 ahead of schedule. first there were blizzards and snowfalls, then freezing rain; in the capital, traffic jams at airports of nine magnitude were delayed and dozens of flights were cancelled. let's ask our meteorologists about forecasts for the weekend. well, let's start with the news.
