Alumina template synthesis is a simple and cheap method for preparing arrays of nanostructural materials, such as wires, fibrils, tubes, which entails the synthesis of desired material within the cylindrically shaped pores by the respective method. To date various materials possessing anisotropic, tunneling, and giant magnetoresistance, superconductivity, semiconductivity, unusual non-linear op...

Using the Car-Parrinello technique, ab initio molecular dynamics simulations are performed for liquid NaSn alloys in five different compositions (20, 40, 50, 57 and 80 % sodium). The obtained structure factors agree well with the data from neutron scattering experiments. The measured prepeak in the structure factor is reproduced qualitatively for most compositions. The calculated and measured p...

Organotin compounds are chemicals composed of tin linked to hydrocarbons, used in industrial materials and various biocides and fungicides. As a result, organotin compounds can enter the environment through a number of channels, and can often be found in seawater, seafood, fruits and vegetables, and consumer goods. Due to the toxicity of these compounds, there is a need for analytical methods a...

We use a first-principles rational-design approach to demonstrate the potential of semiconducting half-Heusler compounds as a previously unrecognized class of piezoelectric materials. We perform a high-throughput scan of a large number of compounds, testing for insulating character and calculating structural, dielectric, and piezoelectric properties. Our results provide guidance for the experim...

The title compounds were synthesized from the elements by heating the corresponding mixtures at high temperature. Their structures were determined from single-crystal X-ray diffraction. Li(9)(-)(x)()EuSn(6+)(x)(), Li(9)(-)(x)()CaSn(6+)(x)(), Li(5)Ca(7)Sn(11), and Li(6)Eu(5)Sn(9) contain columns of stacked aromatic pentagons of Sn(5)(6)(-) that are analogous to the cyclopentadienyl anion C(5)H(5...

Abstract The p-type characteristic of solution-processed metal halide perovskite transistors means that they could be used in combination with their n-type counterparts, such as indium–gallium–zinc-oxide transistors, to create complementary metal–oxide–semiconductor-like circuits. However, the performance and stability perovskite-based do not yet match which limit broader application. Here we r...

The study of inorganic tin (SnCl(2), SnCl(4)) and methyltin compounds (MeSnCl(3), Me(2)SnCI(2), Me(3)SnCl) effects on the enzymatic activity of alcohol dehydrogenase (ADH) in the reaction of ethanol oxidation has been carried out. The experimental results of the study show that inorganic tin and methyltin substances induce slight inhibition of the catalytic activity of horse liver alcohol dehyd...
