Crystalline porous materials (CPMs) have attracted considerable research attention in recent years for their wide applications many fields, such as the energy storage and conversion, gas separation storage, water purification, catalysis, optoelectronics, sensors, drug delivery, etc. The of CPMs derive from superiorities tunable structures, abundant functionalities, excellent chemical stability,...

Layer-like nanocarbons with high surface area and good conductivity are promising materials for supercapacitors due to their good ability for effective charge-transfer and mass-transfer. In this paper, stacked layer-like porous carbon containing RGO (reduced graphene oxides) (LPCG) was constructed via the GO-induced assembly of gelatin followed by carbonization and activation processes. Under s...

Hydrothermal carbonization (HTC) of carbohydrate is an interesting candidate for the preparation of carbon materials, as it provides an easy, inexpensive and environmental friendly route. However, it is difficult to prepare porous carbon materials by a straight HTC process. Herein, the solubilising technology of micelles was introduced to direct the HTC of fructose by using an amphiphilic block...

In this work, the charge dynamics characteristics of injection, transport and decay in porous and non-porous polytetrafluoroethylene (PTFE) film electrets were investigated by means of corona charging, isothermal and thermal stimulating surface-potential decay measurements. The results showed that the initial surface potential, whether positively or negatively charging, is much higher in non-po...

Coral-like porous Si was fabricated through the dealloying of a laser remelted as-cast AlSi12 alloy(Al-12 wt % Si). The porous Si was composed of interconnected micro-sized Si dendrites and micro/nanopores, and compared to flaky Si, which is fabricated by direct dealloying of the as-cast AlSi12 alloy. The structure of the porous Si was attributed to the dendritic solidification microstructure f...

Nestled between the modest pressures employed to study protein folding (a few hundred megapascals) and the very high pressures obtained in shock-wave experiments (in the order of terapascals), a vast pressure scale can be explored experimentally and computationally in the physical and life sciences. Pressure is a powerful thermodynamic variable that enables the structure, bonding and reactivity...

Three-dimensional (3D) nanoporous architectures, possessing high surface area, massive pores, and excellent structural stability, are highly desirable for many applications including catalysts and electrode materials in lithium ion batteries. However, the preparation of such materials remains a major challenge. Here, we introduce a novel method, instant gelation, for the synthesis of such mater...
