Ionothermal carbon materials
… of a fossil-independent energy economy. Porous carbon materials play a major role in many energy-related devices. Among different characteristics, distinct porosity features, e.g., specific surface area (SSA), total pore volume (TPV), and the pore size distribution (PSD), are important to …

Hydrogen Cryosorption of Micro-Structured Carbon Materials
… experimental tests was also performed. Common carbon sorbents, including several Norit branded activated carbons and graphene nanoplatelets (GNPs) with various surface areas, were characterised for their pore structures. The structural differences among GPNs of different surface areas were also …

Ultrasound-assisted synthesis and processing of carbon materials
Part I: Porous carbons are of interest in many applications because of their high surface areas and other physicochemical properties, and much effort has been directed towards developing new methods for controlling the porosity of carbons. Ultrasonic spray pyrolysis (USP) is an aerosol method …

Exploring transport and phase behavior in nanoporous carbon materials
… transport and fluid phase transitions inside carbon nanotube (CNT) nanopores (1-2 nm). For substances confined inside slightly larger pore sizes (roughly 4-25 nm in diameter), methods are presented for predicting the diameter-dependent freezing point changes. This work also demonstrates the …

Advanced Carbon Materials Based Electrodes for High Performance Symmetric Supercapacitors
… are environmental friendly technology. Electrode materials play a key role in the final performance of supercapacitors. Carbon, usually used as symmetric supercapacitors electrode materials, exhibit extraordinary stability in harsh electrolyte and electrochemical performance owing to its physical …

Conversion of Switchgrass into Functional Carbon Materials and Food Emulsifiers
… large-volume commodity products, such as hard carbon and natural emulsifier, to increase the economic gain. First, we designed a process to convert switchgrass into hard carbon, a carbon material with disordered structures, and used as an anode material in sodium-ion batteries. The produced …

Chemistry of novel nanoscale carbon materials: Nanodiamond and carbon nano-onions
Nanoscience is the area of science concerning materials on the level of nanometer scale. Currently much of the discussion of nanoscience is focused on carbon-based nanostructures. Tremendous studies have been carried out on fullerenes and carbon nanotubes in the past a couple of decade due to their …

Novel carbon materials with hierarchical porosity : templating strategies and advanced characterization
The aim of this work was the generation of carbon materials with high surface area, exhibiting a hierarchical pore system in the macro- and mesorange. Such a pore system facilitates the transport through the material and enhances the interaction with the carbon matrix (macropores are pores with …
