Цель работы – исследование влияния параметров синтеза на средний гидродинамический радиус мицелл витамина E (альфа-токоферол ацетат). Проводили многофакторный эксперимент, включающий три входных параметра и уровня варьирования. В качестве выбраны: температура (t), концентрация (С (Е)) ПАВ (Tween 80 или Kolliphor HS 15) С (ПАВ). выходного рассматривали (Rср). рамках исследования E, стабилизирова...

The features of the process growth multilayer heterostructures with InN/InGaN quantum wells (QWs) by method molecular-beam epitaxy nitrogen plasma activation in mode modulated metal fluxes are studied. To compensate for elastic stresses structure, active region was formed form an superlattice matched over average lattice parameter underlying InGaN buffer layer. It has been shown that during rel...

An efficient and expeditious catalyst-free procedure was developed for the one- pot synthesis of 1, 4-dihydropyridine derivatives via the three-component reaction of various aldehydes, ethyl acetoacetate, and ammonium acetate in PEG-400. The reaction was carried out at 110°С and the products were obtained in good to high yields.
