说明

General description

硅胶是硅胶的刚性三维网络。它专门用作齐格勒-纳塔催化剂中活性钛（III）中心的载体材料。硅胶允许可控破碎，导致形成具有窄粒度分布和高堆积密度的均匀聚合物颗粒。硅胶分类如下：
a.水凝胶 - 气孔充满了水
b.干凝胶 - 通过蒸发过程，气孔中的水相被去除
c.气凝胶 - 通过超临界萃取除去的溶剂

Application

硅胶被用于比较MCM-41型中孔吸附剂。

The Effect of Korean Red Ginseng on Bisphenol A-Induced Fatty Acid Composition and Lipid Metabolism-Related Gene Expression Changes.

Joonwoo Park et al.

The American journal of Chinese medicine, 48(8), 1841-1858 (2020-12-11)

Bisphenol A (BPA), which is known to be an endocrine-disrupting chemical (EDC), is associated not only with estrogen activity and reproductive toxicity but also with a variety of metabolic disorders. BPA affects glucose tolerance, cholesterol biosynthesis, and fatty acid synthesis.

Sustainable production of alkyl esters via thermal process in the presence of carbon black.

Eilhann E Kwon et al.

Environmental research, 183, 109199-109199 (2020-02-07)

In this study, it is introduced a sustainable synthetic route of alkyl esters, considered value-added industrial chemicals and fuels, from volatile fatty acids (VFAs) that can potentially be generated from organic waste. In the presence of a porous carbon material

Valorization of sewage sludge via non-catalytic transesterification.

Jong-Min Jung et al.

Environment international, 131, 105035-105035 (2019-07-28)

To seek a way to valorize sewage sludge (SS), it was chosen as a raw material for biodiesel production. As such, non-catalytic transesterification of dried SS was carried out, to enhance its value. Note that picking a waste material such
