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
Scientists have created the storage information of the monolayer of molecules of the salt, which consisted of a flat of organic cation and inorganic anion. Under the tension imposed by the probe of the electron microscope, the anion was above Read more
Chinese chemists have figured out degradation three different perovskite materials through education intermediate phase APbX2.5 (X = I, Br) with ordered vacancies halide ions. Slow degradation maybe the carbon coating that is diffusion barrier for halide ions. Results research published Read more
Scientists from Canada and Germany have created a paper sensor that is sensitive to the presence of air in carbon dioxide of less than six units of ppm. Under the action of carbon dioxide, which is obtained by interaction of Read more
