Cellulose aerogel is an advanced thermal insulating biomaterial. However, the application of cellulose in insulation still faces critical problems, for instance, relatively low strength and large pore size without Knudsen effect. In this study, a silica areogel made from olivine rather than traditional tetraethoxysilane or water glass employed to synthesize silica-cellulose composite applying f...

An optically transparent and thermally insulating (OTTI) silica aerogel demonstrates promising results for various solar thermal applications, particularly concentrated power systems. Higher system efficiency can be achieved by integrating OTTI materials reducing heat loss at higher receiver temperature. However, the stability of aerogels has been one limiting factors. Here, we report that Al2O...

Thermal insulating composites help to reduce the total power consumption in a building by creating a barrier between external and internal environment. Such composites can be used in the roofing tiles or wall panels for exterior surfaces. This study purposes to develop lightweight cement-based composites for thermal insulating applications. Waste materials like silica fume (an industrial by-pro...

Silica aerogel is a class of nanoporous material with extremely high porosity (85–99.9 %) and specific surface area (500–1200 m2/g), as in cause very low density, thermal conductivity. But silica have some disadvantages. One this disadvantages cost. In study, to solve problem has been used cost precursor which rice husk ash. Also, we try improve porosity. To the expanded perlite (EP). produced ...

Cellulose-Derived Aerogels In article number 2102892, Saad A. Khan and co-workers highlight the historical background recent scientific achievements in design, development, performance of hybrid aerogels derived from cellulose. The impact various approaches to incorporate organic inorganic moieties including silica, metal–organic frameworks (MOFs), graphene within aerogel matrix is investigated...

A thermal control architecture design study is conducted for a novel robotic planetary and lunar surface exploration concept. The concept is based on the deployment of a large number of small spherical mobile robots over large areas, which employ hopping, bouncing and rolling as means of locomotion. The aim of the research is to prevent freezing and overheating of the robots, without compromisi...
