“…29 The bottom-up growth of graphene sheets is an alternative to the mechanical exfoliation of the bulk graphite. In bottom-up processes, graphene is synthesized by a variety of methods such as chemical vapor deposition (CVD), 45,46 arc discharge, 47 epitaxial growth on SiC, 48 chemical conversion, 49 reduction of CO, 50 unzipping carbon nanotubes 51,52 and self-assembly of surfactants. 53 The CVD approach to produce graphene relies on dissolving carbon into metal surfaces, such as Ni and Cu that act as catalysts 54,55 and then forcing it to separate by cooling the metal.…”

“…Graphene has recently attracted considerable attention owing to its remarkable electronic and structural properties in many emerging application areas such as electronic devices [1-3]. However, graphene exhibits a zero band gap and nonmagnetic behavior, which limits its application in electronics and photonics [4].…”

Using density functional theory calculations, we have investigated the effects of biaxial tensile strain on the electronic and magnetic properties of partially hydrogenated graphene (PHG) structures. Our study demonstrates that PHG configuration with hexagon vacancies is more energetically favorable than several other types of PHG configurations. In addition, an appropriate biaxial tensile strain can effectively tune the band gap and magnetism of the hydrogenated graphene. The band gap and magnetism of such configurations can be continuously increased when the magnitude of the biaxial tensile strain is increased. This fact that both the band gap and magnetism of partially hydrogenated graphene can be tuned by applying biaxial tensile strain provides a new pathway for the applications of graphene to electronics and photonics.

“…As a ceramic with excellent mechanical and thermal properties [1], silicon carbide is widely used in a lage number of fields, such as porous ceramics [2,3], composite materials [4,5], microscopy technology [6], quantum research [7], nano science and technology [8] and optical components [9,10]. Sintering is the most common method in producing silicon carbide ceramic, including pressureless sintering [11,12], hot pressure sintering [13], spark plasma sintering (SPS) [14,15], hot isostatic pressing sintering (HIP) [16], reaction sintering [17] and so on.…”

Aiming at dense sintering of silicon carbide ceramic, magnesium alloy powder was taken as additive, and silicon carbide powders with two different particle size were sintered by the same hot pressure sintering process. Result shows that ceramic sintered by the powder with larger particle size is denser. Magnesium and carbon segregation is observed in the sample prepared by powder with smaller particle size, in which silicon carbide particles cannot be uniformly dispersed by sintering additives. However, sintering additives distribute homogeneously among silicon carbide particles in the sample prepared by powder with larger particle size, which can effectively play a bonding role. In the selection of liquid phase sintering additives, particle size matching of raw material and sintering additives should be emphasized. Materials and methods Raw materialsSilicon carbide powders (purity >99%) with two different particle sizes were taken as raw materials and 8 wt% magnesium alloy powder as additive (Mg94.0 wt%, Al∼2.5 wt%-3.5 wt%). Average particle sizes of silicon carbide are 0.09 μm and 3.31 μm respectively, and average particle size of magnesium alloy is 86.30 μm.
