“…Electro‐deposition, a well‐known method for the preparation of conducting polymer films on the surfaces of electrodes, has also been applied to the fabrication of rGO hydrogels with 3D interpenetrating microstructure . This method features with unique advantage that the rGO hydrogel is grown on the electrode surfaces and thus can be directly used in electrochemical devices.…”

Chemically modified graphene (CMG) materials have been extensively studied because of their unique structures, excellent properties, and potential applications in energy storage and conversion, catalysis, and environment remediation. However, the unique two-dimensional structure and amphiphilicity make CMG sheets easily restack into irregular aggregates, which greatly reduces their accessible surface area, and thereby deteriorates their performance in practical applications. To exploit their inherent properties fully, CMGs usually have to be fabricated or assembled into functional gels with desired three-dimensional (3D) interconnected porous microstructures. In this review, we summarize the recent achievements in the synthesis of CMG-based functional gels, including hydrogels, organogels, aerogels, and their composites. The mechanisms of gel formation and the applications of these functional gels will also be discussed.

“…Some of the applications include photothermal-electrical (PTE) devices for energy conversion [1][2][3], bio-implantable electronics [4], and laser therapeutic agents for selective elimination of microorganisms [5]. In PTE applications, light is converted to heat, and then converted to electricity, presenting an additional method to fully utilize solar energy.…”

The photo-thermal properties of vertically etched gallium arsenide nanowire arrays are examined using Raman spectroscopy. The nanowires are arranged in square lattices with a constant pitch of 400 nm, and diameters ranging from 50 to 155 nm. The arrays were illuminated using a 532 nm laser with an incident energy density of 10 W/mm 2 . Nanowire temperatures were highly dependent on the nanowire diameter, and were determined by measuring the spectral redshift for both TO and LO phonons. The highest temperatures were observed for the 95 nm diameter nanowires, whose top facets and sidewalls heated up to 600 K and 440 K, respectively, and decreased significantly for the smaller or larger diameters studied. The findings also demonstrate that a photonic lattice consisting of vertically oriented GaAs nanowires allows for optimization of the photo-thermal effect.978-1-4799-5622-7/$31.00 ©2014 IEEE

“…Porous materials have shown great application values in some traditional industries, such as the oil and gas processing, industrial catalysis, adsorption/separation, and fine chemical industries [2][3][4][5]. In more recent decade, they are also being recognized and explored in the research fields of water treatment, sustained release of drugs, and fuel cells, to name a few [6,7].…”

Metal-organic frameworks (MOFs) are a class of porous crystalline materials constructed of metal centres with organic linkers, creating one-, two-, or threedimensional well-organized frameworks with very high surface areas. The study of MOFs has become one of the research hot spots in many fields, owing to the broad potential applications projected for these materials in various areas. It is well recognized that synthesis strategies dictate the structure and thus the properties and performance of the resulted MOFs. This chapter provides a comprehensive up-to-date overview on the modulated synthesis strategies for MOFs. The ability to control crystal morphology and size by a number of modulated synthesis methods is illustrated by the zirconium-terephthalate-based MOF, the UiO-66, and a number of other MOFs.
