The quartz crystal microbalance (QCM) was extended to investigate viscous liquids at elevated temperatures in both isothermal and non-isothermal systems. An analysis of the frequency–temperature behavior of the QCM resulted in a new approach to compensate for the effect of the rate of temperature rise on the theoretical QCM temperature coefficients. The temperature-dependent viscosities of a series...
Unpretreated spent beer grains were successfully used as a basic substrate material for the cultivation of Pleurotus ostreatus. The effects of spent grain types, additives, substrate moisture content, and substrate packing density on the yield and nutrition of fruit bodies were investigated. The cultivation results showed that few fruit bodies were formed on spent grain alone; however, a significantly...
The influence of the density and the type of surface oxygen on the adsorption of berberine alkaloid onto activated carbon was investigated using the molecular dynamics simulation method in vacuum. The carbon surface consisted of a basal plane of graphite and surface oxygen groups which were bonded on the graphite plane in a regular square array with various densities. Two types of surface oxygen groups,...
