or a connection that can be used to produce flexible arrest-screens, good characteristics of color harmfulness is a loose concept , but history can become an exact science. if you manage to determine the real age in the pictures. what progressive dating methods exist today and what discoveries do they allow scientists to make in order to measure the artifact of interest to archaeologists. we need to isolate 1 mg from it, carbon switches on and off the active substances of the drug directly in our body. e, the compound at the same time, and exhibit biological activity can be considered as a drug and have the property of photo switching. one of the early tvs was like an aquarium that showed a black and white picture. now we enjoy a perfectly flat screen that shows the whole spectrum of colors in the world. now close

to the creation of large multimedia systems with a roll-up screen that can be rolled up and unfolded in this way, optimizing the space metal conical materials that can be used for the production of flexible avet monitors synthesized by scientists in the crimea, the advantage of such screens is obvious, at least. they practically do not distort the image, while maintaining the quality even at an angle of 175 °, firstly, if we want to transmit the picture as fully as our eye perceives. the world. we must learn to fully reproduce the three basic pure colors, blue, red and green. now, if the problem of red green is more or less already solved, then blue is still a problem, uh, and scientists theorists and practitioners at universities, institutes and serious factory laboratories are struggling with how to make the blue color more stable? because , uh, if we want to get a long-playing device, then its so much service should be at least 10,000 hours of continuous operation, and

unfortunately most of the blue ones. uh phosphors. they, well, reach a maximum of 1,200,000 - these are substances that absorb energy and convert it into light radiation by chemical nature. they are divided into inorganic and organic and organic there are pros. they consume less energy. they can be used to make flexible screens. they work in a wide temperature range, but at the same time they are expensive and short-lived, perhaps the future lies with hybrid forms, for example, organometallic coordinating colleagues made us a cell based on our compound, which showed very good color characteristics, there are more than 17.000 dprk per square meter, in my opinion, it glows and the service life is more than 100 hours. she, in my opinion, shone, then they just turned it off, because there was nothing with her e. she considers her scientific activity from the point of view of practical application kfu graduates are sure that chemistry, first of all, should be useful to people her dream is

that developments based on these compounds are implemented, for example, as sensors for a pulse oximeter, the same apple developers who introduced to your phones. oled displays. they say that after a certain number of hours their display will burn out, because they are based on organic or metal organic light emitting diodes. we are trying to diversify a list of these creatures, that is, to find substances that will have the same characteristics, but will be more accessible. yes, so that we can implement these technologies. in everyday life, the task of scientists is to obtain the necessary substances and make films out of them, so that they can then stick them on a variety of surfaces, and then we will have a tv that can be rolled up, stored in a convenient place and unfolded when you want to watch good news. sevastopol, in fact, you are also a scientific center. i know that a is uh, the concept scientific and educational center, in which sevastopol is actively included. we have been moving towards this for a very long time, and last year, together with the

republic of crimea, and with the crimean federal university, and as leaders, i and sergey valeryevich aksyonov, we announced the concept of a world-class scientific and educational center for a competition held by the ministry of science education and won and received the status of a scientific educational center. this is a center formed on the basis of two regions of two regional universities of the crimean federal university and sevastopol state university. moreover, they divided the competence. each of the universities. there are projects. here is how this idea develops. what moves? what scientific projects are being implemented? the university is very young, lively , dynamic. we see that any ideas that are formulated by the city are picked up and given from their side. ideas, so i believe in the future of the announcement is clear that the world level, there is limited international recognition today. there, in fact, some kind of sanctions formats. but

if we do things that we ourselves will understand that they work and that will be in demand in our country. they will definitely achieve recognition in the world, because after all, a large number of countries that are ready scientifically and culturally in all others to work with us, the rules of etiquette do not allow us to be interested in a woman. how old is she? well, when it comes to archaeological finds, here age plays a decisive role with it, the lived years can show radiation more accurately, radioactive from this carbon, using the accelerator oil of an electrometer, novosibirsk scientists managed to look into the past 70,000 years. this method of radiocarbon dating was invented back in 1946. because of him, the american was not immediately awarded the nobel prize in chemistry with a bandage. the fact is that with vital concentration. carbon 14 is almost the same, both in plants and animals, but after death, the process of decay of absorbed radiocarbon begins, for example, in a tree whose age is more than 5,000

years, the content of c-14 will be two times less than in what was just cut down, only earlier, to analyze the age of the artifact, specialists needed tens of grams of the substance, which sometimes jeopardized the integrity of the sample itself , something the basis of spectrometry accelerators. this is precisely the piece count and c-14 atoms due to the absence by mail. we need a significantly smaller number of samples. that is, these are not some tens of grams, as one decay would take, but just some milligrams specialist in physics accelerators. alexey petrozhitsky. he likes to solve non-trivial problems , this is exactly what the scientists faced this time, too, because a close collaboration of physicists was required. and chemists but a family of drills with diamonds, nozzles and girls. actually, they cut out such squares about a centimeter by centimeter and the plant is the best preserved. the second stage is about cleaning from organics, the third stage is the dissolution of carbonate during the fourth stage is an additional treatment with hydrochloric acid in order to remove the dissolved co2

the fifth stage is just the same hydrolysis, the transfer of collagen from an insoluble form to a soluble one, and at the end we get such a white powder. uh, so similar to cotton wool, and then you need to turn this substance into a solid skating rink, which can be inserted into the accelerating mass of an electrometer , standard samples with a known concentration are installed further. we have interesting measured samples of unknown age and we have blanks, ie blanks. actually. these are the same graphite, which is obtained from a substance which are so ancient that the weight of 214, which in it was absolutely completely disintegrated according to these dead samples, according to these forms. blanca has become clean, we can judge the degree of cleanliness of the conduct. here are chemical procedures and hydrophytization. here are the remains of ancient animals, archaeologists discovered in one of the scientific expeditions. with the help of the accelerating mass of the spectrometer, it was possible not only to determine the age of the finds, but also to completely change the idea of ​​the geography of human settlement in that period for a long

time, the paradigm dominated in science that on the territory of northwestern siberia , a poleolithic man could not live, in general, that part of this time was occupied by a glacier, and the rest of the time was occupied by a lake. e, therefore, a person could not live there, and geologists gradually refute this concept and came to the conclusion that there was no sea, the glacier retreated much earlier. after this case. little is left for archaeologists to geologists, who have confirmed and found the remains of a person that belong to a period of about 40,000 years ago and this date. we know too thanks to the ounce we dated bones and remains of the soil in which ancient objects were found. and now this discovery is accelerated. in novosibirsk, the only such installation in russia. in addition to archaeological research, the ultrasensitive method of isotope analysis of substances is used in biology, medicine and ecology. telekinesis by the power of scientific thought chemists

of st. petersburg state university have synthesized a unique organic compound. this substance can be controlled by the action of a laser. activity and turn it off, when necessary, on the basis of these compounds it will be possible to create drugs with controlled properties that are indispensable in personalized medicine, but our main advantage is that our e compounds at the same time, but also show e, biological activity can be considered , as a medicine. and a have the property of photo switching and also, uh, i would say that we managed to synthesize. e big group. a whole, whole series of compounds possessing. uh, such properties, as scientists say, such a discovery of a kind, an accident obtained by chemists, the compound does not just react to light, but changes its shape under the influence of a laser, and significantly changing its biological activity.

this is a solution of a synthesized fas fan. i would like to point out that initially the stock solution was colorless, but uh, after about 30 minutes of radiation. we will see that its color will change. and why, that is, what happens at the chemical level in the solution that it changes color we it was assumed that, with laser radiation , the geometry of the molecules changes, that is, the geometry rotates and its optical properties change, that is, the geometry is simply, well, the ratio of e relative to each other . the atom that makes these molecules rotate is absolutely correct, more precisely, a certain chemical group. in this molecule rotates and because of this there is a change in the optical properties change. i understand, not only optical properties. absolutely correct change, as well as functional properties. ilya kolesnikov material. no, by education he graduated from the faculty of physics, freedom, his main area. so research is luminescence, and at the level of nanoparticles in this development, it emits the optical properties of the compounds obtained. i mean,

this is the first time. when succeeded. in fact, to detect such molecules that change their biological activity under the influence of a laser absolutely right, usually in order to create a photopharmacor. uh, there are two necessary ingredients, i.e. a substance that heals a substance that reacts to laser radiation. we managed to create for the first time such a substance, which consists of one molecule. how is this going to happen in practice? we can treat skin diseases locally with laser irradiation and treat only those areas of the skin without affecting others, but in which it really has problems. that is, potentially chemists are already considering. this is a connection. as a basis for the production of drugs for further research, scientists received a grant from the russian science foundation. how often do we turn the lights on or off without thinking that literally a century ago for a person, it was a real miracle, literally a couple of decades will pass, and in the same way, with the help of light,

we will turn medicines on or off right inside our body, and we will stop drinking, guests of the bioavailability pills that depend on, but from 1,000 factors. it was a science program. i'm natalia popova see you.

dear

friends, i want to offer you a mini-series of very small films that we shot almost 30 years ago. i thought about what, probably, painting pictures they should speak, that is, the idea arose to try to hear what the artist could hear when he painted a portrait or landscape? it seems to me that it makes sense to recall who all the same is, russian culture, in particular, yes, russian painting. which shocked the world at the time.

and the main events of this minute in our news release and so in moscow ended the main football confrontation of the country cska against spartak, the meeting ended in a fighting draw 2: 2, our sports observer followed the game danilo makhalin. he comes out with us directly, danila is welcomed so he was also closer to victory. yes, welcome, a big sign in russian football spartak-tssk and most of the fans' predictions, before this match, the score was 2: 2 two

teams play attacking football is at the top of the tournament.
