A simple analytical procedure is proposed for simultaneous determination of three common dyes (Basic Blue 9, Brilliant Blue E-4BA, and Reactive Blue 2) in natural waters without prior separation of the solutes. A popular chemometric method, partial least squares regression PLS-1, was effectively applied for spectral resolution of a highly overlapping system. At the best modeling conditions, mea...

Modern software development without reactive programming is hard to imagine. Reactive programming favors a wide class of contemporary software systems that respond to user input, network messages, and other events. While reactive programming is an active field of research, the implementation of reactive concepts remains challenging. In particular, change detection represents a hard but inevitab...

Fe-BiOCl-Vo nanosheets with electron-capture centers of doped Fe and surface oxygen vacancies (Vo) for enhanced photocatalytic-Fenton performances were conducted. Compared pristine BiOCl nanosheets, the band gap resulting was narrowed, defective bands introduced due to doping Vo. Furthermore, integrated electron trapping effect Vo can efficiently drive charge transfer separation. As a result, p...

Different synthesis temperatures (450–550 °C) were applied to synthesize g-C3N4 with the highest visible-light triggered photocatalytic activity. The best performing photocatalyst was synthesized at 550 °C due created favourable structure that expressed lowest band gap and charge carrier recombination rate. To further improve activity of g-C3N4, different g-C3N4/TiO2 (gCN/TNP) composites varyin...

Emulsion-enhanced biphasic esterification has proven to be applicable for carboxylic acid recovery from dilute aqueous process streams. The is esterified with 1-octanol in an emulsified regime 4-dodecylbenzenesulfonic (4-DBSA) or Ni(DBSA)2 as catalyst. After phase separation, the laden solvent must regenerated. This study presents a regeneration concept based on reactive distillation transester...

The atomistic model of amorphous silicon-carbide membrane that was developed in Parts I and II of this series is utilized in nonequilibrium molecular dynamics (MD) simulations to study transport and separation of equimolar gaseous mixtures H2/CO2 and H2/CH4 in the membrane at high temperatures. We simulated membranes with up to about 39 nm in thickness, containing up to 170,000 atoms, and up to...

Methyl propionate, also known as methyl propanoate, is a clear colourless liquid with a characteristic odour (fruity smell and taste). In this study, the formation of methyl propionate through the esterification of propionic acid and methanol was investigated in the reactive distillation system using a conventional (CBD), single feed (SF-SBD), and double feed semi-batch distillation (DF-SBD) co...

Porous hollow glass microspheres have many uses, including encapsulation of active materials. In this paper a fast and facile method for fabricating porous hollow glass-microspheres was demonstrated by etching them using dilute hydrofluoric acid. Then, a highly reactive amine was infiltrated into the etched glass microspheres. Scanning electron microscopy was conducted for the hollow glass micr...
