Graphene-based sheets show promise for a variety of potential applications, and researchers in many scientific disciplines are interested in these materials. Although researchers have developed many ways of generating single atomic layer carbon sheets, chemical exfoliation of graphite powders to graphene oxide (GO) sheets followed by deoxygenation to form chemically modified graphene (CMG) offe...

Differential scanning calorimetry (DSC) and X-ray powder diffraction (PXRD) have been used to determine the phase behavior of the binary mixtures of undecanoic acid (A) and undecylamine (B) in the bulk. In addition, we report DSC data that indicates very similar behavior for the solid monolayers of these materials adsorbed on the surface of graphite. The two species are found to form a series o...

TiB₂-based ceramic matrix composites (CMCs) were fabricated using elemental powders of Ti, B and C. The self-propagating high temperature synthesis (SHS) was carried out for the highly exothermic "in situ" reaction of TiB₂ formation and the "tailing" synthesis of boron carbide characterized by weak exothermicity. Two series of samples were fabricated, one of them being prepared with additional ...

As one of the most important two-dimensional (2D) materials, BN nanosheets attracted intensive interest in the past decade. Although there are many methods suitable for the preparation of BN sheets, finding a cheap and nontoxic way for their mass and high-quality production is still a challenge. Here we provide a highly effective and cheap way to synthesize gram-scale-level well-structured BN n...

The graphite/silicon-based diffusion-dependent electrodes (DDEs) are one of the promising electrode designs to realize high energy density for all-solid-state batteries (ASSBs) beyond conventional composite design. However, also suffers from large initial irreversible capacity loss and fade caused by significant volume change during cycling, which offsets advantages DDEs in ful-cell configurati...

This paper introduced several kinds releasing agent, summarized analyzed advantages present situation domestic foreign research, prospected future

Graphite-molybdenum-titanium composites might attract significant interest as heat sinks for different sector applications due to their excellent thermal, electrical and mechanical properties. This type of was already studied but following the powder metallurgy spark plasma sintering (SPS) route. The aim present investigation is study a new route fabrication these improve properties: colloidal ...
