We describe an experimental method for studying rapid processes of water vapor sorption by fine-dispersed and porous materials. The concentration of gas-phase water molecules is detected during adsorption by a laser-diode spectrometer. The kinetic pr

The kinetics of water vapor adsorption on the porous silicon surface is studied by the gas relaxometry method. The process multistepping which is reflected in sequential changes in H2O molecule diffusivities into the porous matrix, is found. Phenomen

A device for recording high-speed processes of water-vapor sorption at the surfaces of porous materials is described. The water-vapor pressure over a sample is measured during the sorption process by registering the integral intensity of the absorpti

A method is proposed for detecting spectral characteristics of optically inactive molybdates of rare-earth elements by their doping with rare-earth ions whose luminescence lies in the transparency region of all structural modifications of the sample.
