It is known that aerogel impregnated fibrous blankets offer high acoustic absorption and thermal insulation performance. These materials are becoming very popular in various industrial building applications. Although the reasons for performance of these well understood, it still largely unclear what controls their Additionally, only a small number publications to date report on acoustical prope...
Abstract Rice Husks (RHs) are one of the most abundant sources biomass in world due to rice consumption. Lignocellulose and silica two main components RHs, which allow RHs be applied different areas. can partially dissolved 1-butyl-3-methylimidazolium chloride (BMIMCl), is a simple way competing with traditional extraction methods that suffer from high chemical A lignocellulose freeze gel obtai...
The ultrahighly nanoporous aerogel is recognized as a state of matter rather than as a functional material, because of its qualitative differences in bulk properties, transitional density and enthalpy between liquid and gas, and diverse chemical compositions. In this review, the characteristics, classification, history and preparation of the aerogel were introduced. More attention was paid to t...
