The steric hindrance in molecules of 1-(2,4,6-trimethylphenyl)ethanone and 1-(2,4,6-triisopropylphenyl)ethanone were shown to substantially differentiate the options of synthesis of the respective alcohols. The former was obtained with a yield of 12%

The influence of the lanthanum and barium addition on the physicochemical properties and catalytic behavior of the Ru/C catalyst for CO methanation was investigated. The catalyst was doped with La or with La plus Ba. It was found out that there are v

A series of 20 wt.% MO2/S catalysts (where M = Ce, Mn or Zr and S = SiO2 or Al2O3) were prepared using various precursors of the active phases. The resulting catalysts were characterized using different methods (XRD, TPR and SBET). For the first time

There is growing recognition that the degradation of plastics in the environment is a serious problem. This study investigated and reported on the feasibility of removing end-of-life plastics from circulating in the environment. The specific example

Although heterogeneous monometallic gold catalysts are commonly more active when the gold particles are smaller, this study shows that the reverse is true in the case of liquid phase catalytic transfer hydrogenation of acetophenone with 2-pentanol. H

The most important goal of every water distribution system is to deliver water to the consumers in the demand and time determined by its users. However, not all water usages require the potable water quality. One of the technical solutions enabling w

Fractals are self-similar sets that can not be easily described by classical geometry. Fractals sets have been implemented in almost all areas of human activity since they were introduced to science by Mandelbrot in 1982. For the last 10 years, an in
