Aug 28, 2019· Hydrophobic silica colloid electrolyte holds promise for safer lithium-oxygen batteries ... strong electrical field during the lithium deposition process. A hydrophobic silica colloid ...
Hydrophobic silica is a form of silicon dioxide (commonly known as silica) that has hydrophobic groups chemically bonded to the surface. The hydrophobic groups are normally alkyl or polydimethylsiloxane chains. Hydrophobic silica can be processed in different ways; such as fumed silica, precipitated silica, and aerosol assisted self assembly, all existing in the form of nanoparticles
A hydrophobic silica colloid electrolyte (HSCE) with a low diffusion coefficient of 10 wt% along with the hydrophobic property of silica led to a 980-times better anticorrosion effect, thus ...
Precipitated silica, a form of synthetic amorphous silicon dioxide, is derived from quartz sand, a crystalline form of silicon dioxide. The physical properties of precipitated silica can be manipulated during the manufacturing process to deliver products with a wide range of performance-enhancing features engineered for many different end-use applications.
Rooftop solar thermal collectors have the potential to meet residential heating demands if deployed efficiently at low solar irradiance (i.e., 1 sun). The efficiency of solar thermal collectors depends on their ability to absorb incoming solar energy and minimize thermal losses. Most techniques utilize a vacuum gap between the solar absorber and the surroundings to eliminate conduction and ...

Fumed silica and Precipitated silica. Fumed silica and Precipitated silica. Both of fumed silica and precipitated silica are silicas, or silica dioxide(SiO2). Their cost different is mainly due to different production technology and raw materials. Fumed silica and precipitated silica are for different applications. As a result of their ...
The only example of process-scale purification of proteins using underivatized silica dealt with purification of insulin-like growth factor-I and related proteins (Reifsnyder et al., 1996). Underivatized silica was shown to provide similar performance as CPG at a fraction of the cost. The structure of silica gel consists of an amorphous

Ice adhesion test results show that the ice adhesion strength is reduced remarkably by silica-based nano-coatings. The bouncing phenomenon of water droplets, the icing delay performance and the lower ice adhesion strength suggest that the super-hydrophobic coatings based on a combination of silica and POTS also show icephobicity.
