Canadian scientists have developed an approach to treatment of tissues with mixture of polydimethylsiloxane to impart oleophobic properties and tested it on a metal mesh and nylon jacket. Water and oil droplets formed with a treated nylon cloth edge angles Read more
American scientists analyzed the isotopic composition white lead on ritual vessels Inca the colonial period. It turned out that part of the vessel was painted white, brought from Europe and part – whitewash made from lead rocks of the Andean Read more
Chinese scientists have created an alloy with sverkhreshetkakh structure, which has outstanding heat resistance and ductility at room temperature. Disordered interfacial structure of nano layer differed significantly from that observed previously in similar alloys. Its presence enabled the material to Read more
Japanese chemists have developed a catalyst based on lanthanum nitride with the addition of Nickel, check its ability to accelerate the reaction of formation of ammonia from nitrogen and hydrogen and established the mechanism of the processes. The material allowed Read more
American chemists have synthesized and tested for ability to protect against x-ray radiation, nanoparticles of selenometionina — pheomelanin with atoms of selenium instead of sulfur. The use of biocompatible suspensions of particles allowed to protect living cells from exposure to Read more
Scientists scientifically substantiated of the traditional method of determining the concentration of ethanol in the distillation of mezcal for the lifetime of the bubbles. The presence of surface-active agents, the desired degree of viscosity and ethanol content of about 55 Read more
American scientists have created a battery based on liquid metal, separated by an electrolyte made of organic material that works at room temperature. In acts as an anode alloy of sodium with potassium, and as the cathode — liquid alloys Read more
scientists have synthesized and investigated crystal structure and properties of boride tungsten WB5-x. Mechanical properties of the material were not significantly worse than the calculated values, which makes these materials promising for use in technical fields where need the solid Read more
Chemists from the Netherlands created arbitrarily formed in an aqueous solution system, capable of self-replication and protometabolism. Under the light of the dye associated with other structural units of the growing fibers, catalyzed reaction of self-replication and growth of fibers. Read more
Chemists have synthesized a porous polymer sorbent, which was able with the efficiency of more than 99 percent selectively to adsorb the precious metals from complex multicomponent mixtures. One gram cheap cost polymer bound more than half a gram of Read more
