From studies of the emission spectra of 9-cyanoanthracene (9 CNA) solutions, glasses, polycrystalline films and single crystals at 298 and 77 K a centrosymmetric excimeric species with emission maximum at ≈ 490 nm has been ...

Real time estimation of target quality variables using soft sensor relevant to time varying process conditions will be a significant step forward in effective implementation of Industry 4.0. Generalized Regression neural ...

Ergonomic Design and Workplace Assessment are the major disciplines that govern the Occupational Health and Safety of a Process Industry.This paper highlights the various factors that are vital to these disciplines in the ...

Adsorption of n-butenes on highly activated type A-zeolites containing alkali and alkaline earth cations is studied by infrared spectroscopy. The rate of adsorption is determined by the butene–zeolite interaction, depending ...

The application of the Lux–Flood concept to acid–base reactions in oxide systems is discussed in the light of spectroscopic information concerning the “state” of oxide ions. In slag systems (e.g. molten silicates) it is ...

The multiple states of electrosorbed H and oxygen species at Pt, which arise below monolayer coverage, are of current interest in electrochemical surface science. The results of experiments on the effects of high hydraulic ...

A comparative study of nitrogen (78 K) and water vapour (273–298 K) adsorption isotherms has been carried out with precipitated silica, a flame hydrolysis product (Cabosil) and with surface modified Cabosil obtained by ...

Equilibrium vapour pressures of 1,3,5-trinitrobenzene (TNB), 2,4,6-trinitrotoluene (TNT), 2,4,6-trinitro-m-xylene (TNX), 2,4,6-trinitromesitylene (TNM), 2,4,6-trinitroaniline (TNA), 2,4,6-trinitro-m-phenylene diamine (DATB), ...

The strength and number per unit surface area of acid sites on a series of silica—aluminas of composition ranging from 0 to 100 % in alumina have been investigated. The results of titration by n-butylamine in the presence ...

An e.s.r. study of the ion pair formation between pyrene and alkali metals in various ether solvents has been carried out. Depending on the nature of the solvent and the alkali metal ion, various types of species are ...
