    How to make Plutonium

    Physicists at Oak Ridge National Laboratory (ORNL) have developed a new method for the automated production of plutonium-238, which will increase its production eightfold.

    Previously, a radioactive isotope was mainly needed for nuclear weapons, and now it is used for medical sterilization, artistic restoration, power supply of spacecraft systems and other peaceful purposes. After the end of the Cold War, many governments scaled back their national production programs, although need in radioisotope preserved. ORNL researchers have been making it by hand, but recently figured out how to automate the process..

    To do this, they form neptunium-aluminum oxide granules. Neptunium is also a radioactive metal element, and if the granules are further irradiated, the so-called neptunium-238 is created, which quickly decays and forms usable 238Pu.

    According to scientists, partial automation of production will increase the annual production of plutonium from 50 g to 400 g. Additionally, the reduction of manual operations reduces the level of potential risks..

    Chinese scientists have also made incredible progress in transforming atoms. They were able to turn copper into an analogue of gold.

    New non-electric system can simultaneously cool the building and heat the water

    Unique Heating, Cooling and Hot Water Solutions for Multi-Storey Buildings

    Scientists have developed a prototype of a hybrid device that can not only reduce the temperature in a building by 12 °C without electricity, but also heats the water due to sunlight.

    Heating and air conditioning systems are among the main consumers of electricity. Therefore, researchers are improving radiation cooling systems. and heating for light renewable energy sources. Now a team at State University of New York at Buffalo has combined the two concepts in one device..

    To create it, the researchers installed a heat emitter in such a way that heat from the room was collected from both sides of the panels and transferred into the open space in the form of infrared waves. They positioned the thermal emitter vertically between a pair of V-shaped mirrors. In the course of experiments, the device reduced the temperature inside the test setup by more than 12 °C  in direct sunlight and at least 14 °C in simulated night time.

    The system uses mirrors consisting of 10 thin layers of silver and silicon dioxide, which selectively interact with waves of different lengths. They reflect mid-infrared waves from the emitter, absorbing visible and near-infrared rays. This improves the efficiency of the device as it prevents the sun from neutralizing the cooling effect..

    New non-electric system can simultaneously cool the building and heat the water

    Since the system reflects only part of the radiation, the team decided to use the absorbed energy to the advantage. During tests, researchers were able to use it to heat water up to 60 °C.

    The current prototype is only 0.7 m long.In the future, scientists plan to scale the device to the size of the roof.

    Scientists have made fiber from algae

    Researchers have created biocompatible, biodegradable and edible fiber from natural gel that can have many medical uses.

    The team of scientists from the University of Campinas used conventional agar-agar made from seaweed as the main material for the optical fiber. The wire they created with a diameter of 2.5 mm has six cylindrical holes of 0.5 mm along the inner axis. They are located around a solid core and prevent light scattering due to the difference between the refractive indices of the gel and air..

    Waveguide parameters can be adjusted by changing the composition of natural gelatin, the shape and size of the cores for holes during pouring.

    Scientists made fiber optic from algae

    Tests have shown that the gel undergoes structural changes under the influence of temperature, humidity and pH. This allows it to be used for optical sensing, the creation of biocompatible optical sensors, disposable Petri dishes, various devices for operations, research and localized drug delivery..

    Scientists are experimenting with other materials, for example, recently the Finns made fiber from cellulose.

    The new ABBYY system recognizes text as well as the human brain

    1 Comment

    ABBYY has integrated AI into its new text recognition system, which allows it to independently determine the peculiarities of handwriting or printing on individual images.

    Although programs for translating scans into an editable file appeared in the last century, their main problem was recognition by comparing elements a snapshot with a set of symbols in their database. Therefore, when processing images with minor changes, often the wrong letters were displayed, which required proofreading and manual correction of errors.

    Russian developer ABBYY solved this problem using neural networks. The presence of AI elements in the recognition system allows it to work like a human brain, determining the individual characteristics of the spelling of letters. At the same time, it does not wait for the database to be updated, but independently compares the sets of scanned characters with those already known, and expands the list of possible spellings. Details can be found in patent.

    The new ABBYY system recognizes text as well as the human brain

    This speeds up the processing of scans with imperfections, documents with displaced lines, poorly printed elements, and images with hieroglyphs, Arabic script.

    However, competition in this market continues to intensify. In May, Amazon also introduced a new Textract service AI-powered document processing that fully automates data entry.

    Astronomers first spot water on a potentially habitable planet

    A Potentially Habitable Super Earth Has Been Discovered

     

    Found the first planet outside the solar system, which has not only water, but also the necessary temperature conditions to support life.

    K2-18 orbits a cool dwarf star 110 light years away in the constellation Leo. It is eight times heavier than Earth and has a different composition of the atmosphere. Given the high level of activity of the red dwarf, the conditions on it are likely more hostile., as it must be exposed to strong radiation.

    Although this exoplanet will not be able to become a new home for humanity, the discovery brings us closer to answering the fundamental question about the uniqueness of the Earth..

    In their work, a team of astronomers at University College London used archival data from 2016 and 2017 from the Hubble Space Telescope and developed open source algorithms to analyze the starlight that passed through the atmosphere of K2-18b. The results showed the presence of water vapor, hydrogen and helium. Researchers believe other molecules, including nitrogen and methane, may also be present in the atmosphere, but further research is needed to find them..

    Astronomers first spot water on a potentially habitable planet

    K2-18b was discovered in 2015 and is one of hundreds of super-earths – planets with masses between Earth and Neptune – found by the Kepler spacecraft. Scientists believe many of these super-Earths will be found over the next few decades, as they are the most abundant type of planet in our galaxy, and red dwarfs are the most common stars..

    Recall that last year NASA announced that it will begin to look for signs of advanced forms of extraterrestrial life..

    North and South Korea will investigate the human genome

    Two South Korean companies Macrogen and Bigster have announced a partnership. In an unexpected turn of events, the news that the development team also includes specialists from North Korea. Previously, there were not many joint projects of the two countries in the scientific community..

    The joint efforts will focus on the development of a blockchain platform that will facilitate the transfer and storage of genome data. Through this platform, organizations hope to offer a safe and sustainable method of handling genetic information. Macrogen believes that the human genome — it is one of the most important research topics in health care.

    Individual genome data can enable physicians to improve their work efficiency (in particular, diagnostics) and improve the techniques of treating their patients. Also, work in this area will allow pharmaceutical companies to develop new drugs and therapeutic drugs..

    Although genetic information is widely used in health care, its confidential nature, including details such as the biological characteristics of individuals, requires special conditions for the storage and transmission of data. Macrogen claims that they need cryptographic and non-cryptographic methods of protection against hacking in order to work. Confidentiality risks are assigned a special role.

    North and South Korea will investigate the human genome

    Working on the basis of blockchain, based on decentralization and distribution of data will eliminate the risks of accidental changes or hacking of genetic information. Given the confidential nature of such data, the biotech company decided to use a consortium  a model whereby participation in the blockchain is limited to key parties such as pharmaceutical companies, research organizations, genomic analysis groups, and hospitals. The Seoul firm believes this model will be easy to expand for further management..

    Bugatti Chiron sets new speed record of 490 km / h

    490+ kilometers per hour | Bugatti Chiron | Speed record

    Bugatti has unveiled the fastest passenger car to date, which can accelerate to 490 km / h, but for this the engineers had to redesign and reinforce the wheels.

    Initially, the Chiron could not reach its maximum, because at speeds over 480 km / h, the wheels overheated due to strong centrifugal force and a tire load of about 7 tons, from which they were torn apart. However, the designers decided not to look for another rubber, but to strengthen the tires. and redesign the vehicle to reduce drag and eliminate downforce from both sides.

    As a result of tests at the Volkswagen Ehra Lessein proving ground in Germany, the pilot managed to accelerate to 490 km / h, installing a new world record. The track itself was perfect for testing, but it took more than five hours to clean it up at this speed. Although at the finish the windshield was littered with smudged insects.

    Despite the huge potential of the Bugatti Chiron, future owners will not be able to fully realize it, as the cars sold will be limited to 440 km / h. However, hardly anyone will try to accelerate to this speed, if only due to the lack of a suitable track..

    As a reminder, Lamborghini unveiled its first hybrid supercar Si in September.án, which will be the most powerful and fastest car of the company.

    Created a self-healing filter that does not allow bacteria and gases to pass through

    Tips for BLOATING with Crohn’s Disease

    Mechanical engineers at Pennsylvania State University have created a fluid membrane that allows large objects to pass through and traps small objects. The material is self-regenerating, stabilized, has many properties of the cell membrane and is the complete opposite of a conventional filter..

    The simplest example of a filter is a sieve. If sugar and peas are poured into it, then it detains larger objects. The invention of the Pennsylvania scientists works the other way around. The principle of operation of a liquid membrane is based on kinetic energy, which is usually proportional to size, to achieve the desired reversing effect. After passing the object, the shape is completely restored like a layer of surface tension on the top of the glass.

    The liquid membrane looks like a regular bubble blowing ring. It is based on water and many other components, and the first prototypes consisted partially of soap. In the course of further research, the content was greatly changed. Thanks to this, the membrane has now become stronger, and also received antibacterial properties and the ability to neutralize odors. Now it can function for a long time and even blocks certain gases..

    UK wants to build an orbital power plant by 2050

    UK wants to build an orbital power plant by 2050

    UK government commissioned a study to assess the cost-effectiveness of a solar power plant in geostationary Earth orbit.

    When solar panels are operated on the planet’s surface, their overall efficiency is significantly reduced due to a number of physical factors. They do not generate electricity at night, they do not work well in cloudy weather, without special mechanical systems, their power fluctuates depending on the angle of incidence of rays during the movement of the Sun during the day, some of which are absorbed by the atmosphere. All of these factors disappear when the panels are installed in space..

    The UK space agency was interested in such an opportunity and instructed the consulting company Frazer-Nash to study the issue. The research team will study not only the feasibility of the project from the financial side, but also the specific technical features of construction, possible solutions to maximize efficiency, as well as the impact on the country’s energy sector.

    UK wants to build an orbital power plant by 2050

    All the necessary technologies to create a space solar power plant have existed since the 80s of the last century, but until now such projects have been postponed due to the complexity of implementation and high costs. That changed in early 2019 when China announced it was designing a space facility. for converting solar energy into electrical energy, with its subsequent transfer using a laser or microwaves to the Earth.

    Frazer-Nash Consultancy will work with space organizations, energy companies and scientific institutions to determine the best way to transfer the energy produced in orbit to the surface. In case of a positive assessment, the government plans to implement the project until 2050.
