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
Scientists experimentally showed that the change in properties of the solution of alkali metals in ammonia from electrolytic to metal gradually. In the spectra of x-ray photoelectron spectroscopy of solutions of various concentrations, the authors found that with increasing the Read more
Swiss physicists have created a molecular motor of 16 atoms, which comprises the stator of a three-layer cluster compounds of palladium with gallium and the adsorbed molecules of acetylene as the rotor. The rotation of the acetylene occurs under the Read more
German scientists have created a material based on calcium phosphate cement with carbon fibres that can withstand shock loadings up to 1.9 kilojoules per square meter. The material was able to heal cracks of up to ten microns in its Read more
Us scientists have synchronised the system CRISPR-Cas9 with the help of light. Photosensitive chemical modification guide RNA have allowed not only at the same time to cut DNA in a population of cells, but also to make it much faster Read more
Scientists from St. Petersburg have registered the formation of halogen relationships between carbon isocyanide groups with iodine in the iodine substituted perforating. Such non-covalent binding of reduced volatility, and, respectively, and the smell of foul-smelling isocyanides without losing their reactivity. Read more
Scientists from the Netherlands and Iran proposed a method of controlled set and the allocation of ultrasmall liquid volumes (less than one picoliter) through the probe tip of the atomic force microscope to simultaneously study surface topology. The results of Read more
Chemists learned clean ethylene from acetylene using zeolite material, doped Nickel. Due to the ability of Nickel to form complexes with acetylene so it can be cheap and easy to obtain ethylene of very high purity (impurity acetylene is less Read more
