AbstractIn recent decades, carbon aerogels (CAs) have attracted increasing attention. Compared with other carbon materials, CAs are available in macroscopic diverse morphologies with tunable hierarchical porosity and large specific surface area. The interconnected carbonaceous framework also endows CAs with excellent electrical properties. CA can be a promising material for various purposes through proper design and functionalization. In this article, we place an emphasis on CAs based on resorcinol-formaldehyde resin and graphene sheets. We review the state-of-the-art progress on the preparation of functionalized CAs, and the relationships between their advanced nanoarchitectures and performances in environmental remediation, including adsorption, capacitive deionization and catalysis, are discussed. The challenges in design and application of CAs are also proposed.

Cell Organization

The extraction of lipids from tissues during fixation and embedding for electron microscopy is widely recognized as a source of possible artifact, especially at the membrane level of cell organization. Lipid extraction is also a major disadvantage in electron microscope autoradiography of radioactive lipids, as in studies of the uptake of radioactive fatty acids by intestinal slices. Retention of lipids by fixation with osmium tetroxide is generally limited to glycolipids, phospholipids and highly unsaturated neutral lipids. Saturated neutral lipids and sterols tend to be easily extracted by organic dehydrating reagents prior to embedding. Retention of the more saturated lipids in embedded tissue might be achieved by developing new cross-linking reagents, by the use of highly water soluble embedding materials or by working at very low temperatures.

Mesoporous Carbon Materials

Nitrogen-doped mesoporous carbon materials have been synthesized by using melamine-formaldehyde resin as carbon precursor and SBA-15 as a removable template. The structure of the materials was investigated by X-ray diffraction, BET specific surface area analysis, Fourier transform infrared spectroscopy, and thermogravimetric analysis. X-ray and BET studies confirmed that a pore nanostructure is inherited from the silica templates. Fourier transform infrared spectroscopy analysis showed N atoms are strongly bonded in the carbon structure in heterocycles or nitrile functions. These mesoporous nitrogen-doped carbon materials exhibits textural properties with BET surface areas ranging between 400 and 600 m2/g and uniform pore size(3.9 nm). The mechanism of carbonization process is studied by thermogravimetric analysis. The ratio of melamine/formaldehyde plays an important role during the carbonization process for the surface areas and textural properties, and element analysis reveals that the nitrogen content of the mesoporous carbon materials is as high as 10wt%.
