Study on diffusion coefficient of benzene and ethyl benzene vapours in nanoporous silica aerogel and silica aerogel-activated carbon composites
In this study, nanoporous silica aerogel and silica aerogel-activated carbon composites have been synthesized using a water glass precursor by cost effective ambient pressure drying method. Equilibrium and kinetics of benzene and ethyl benzene adsorption on silica aerogel and its composites have been measured in a batch mode at tree weights of adsorbent. For the first time, the experimental dat...
متن کاملAdsorption and desorption performance of benzene over hierarchically structured carbon-silica aerogel composites.
Hierarchically structured carbon-silica aerogel (CSA) composites were synthesized from cheap water glass precursors and granulated activated carbon via a post-synthesis surface modification with trimethylchlorosilane (TMCS) and a low-cost ambient pressure drying procedure. The resultant CSA composites possess micro/mesoporous structure and hydrophobic surface. The adsorption and desorption perf...
متن کاملOccupational Radiation Protection: Protecting Workers against Exposure to Ionizing Radiation
The 1984 International Labour Conference Resolution concerning the improvement of the working conditions and the environment laid down the fundamental objectives and principles on which the Infocus Programme on Safety and Health and the Environment (SafeWork) of the International Labour Organization (ILO) is based. The protection of the worker against ionizing radiations falls naturally within ...
متن کاملFeasibility study of silica aerogel nanocomposites application to enhance acoustic properties
Background and Objective: Noise pollution is one of the serious environmental issue. Sound control technologies based on sound absorption and sound insulation are considered as the two widely used methods. Therefore, the aim of this study was to modify silica aerogel nanocomposites to improve its acoustic properties. Materials and Methods: This applied experimental research involved in examin...
متن کاملOptical shock waves in silica aerogel.
Silica aerogels are materials well suited for high power nonlinear optical applications. In such regime, the non-trivial thermal properties may give rise to the generation of optical shock waves, which are also affected by the structural disorder due to the porous solid-state gel. Here we report on an experimental investigation in terms of beam waist and input power, and identify various regime...
