There is intense interest in graphene in fields such as physics, chemistry, and materials science, among others. Interest in graphene's exceptional physical properties, chemical tunability, and potential for applications has generated thousands of publications and an accelerating pace of research, making review of such research timely. Here is an overview of the synthesis, properties, and applications of graphene and related materials (primarily, graphite oxide and its colloidal suspensions and materials made from them), from a materials science perspective.

Honeycomb Carbon: A Review of Graphene

The layered perovskite K2La2Ti3O10 photocatalysts have been successfully synthesized by soft hydrothermal method The effects of hydrothermal temperature, reaction time, and KOH concentration on morphologies and sizes of the particle were investigated, and characterized by powder diffraction, UV–vis reflectance, and specific surface area measurements The photocatalysts prepared by hydrothermal technique had a higher photocatalytic activity than that prepared by conventional solid state reaction method

Hydrothermal Synthesis of K2La2Ti3O10 and Photocatalytic Splitting of Water.

Mineral powders have not been used to reinforce silicone rubber so far, although they have been used as fillers in other rubbers1. If a natural mineral powder, after being processed by physical and/or chemical methods, can be used as a reinforcing filler for silicone rubber to replace expensive fumed silica, it will not only promote the development of the silicone rubber industry, but also enhance the usefulness of the minerals2.

Figure 1. Experimental and simulated X-ray powder diffraction patterns of complex 1. Open-framework materials, especially those of metal phosphates, have been of great interest in the past few years because of their potential applications in catalysis, sorption, ion-exchange processes and other areas, and also due to the fascinating structural features exhibited by them. Continued research in this area has shown that these materials are generally prepared under hydrothermal conditions in the presence of structure-directing organic amines (templates). It is well established that open-framework tin(II) phosphate compounds can be synthesized with the aid of organic structure-directing amines. From the perspective of structure, a tin atom will link with either three oxygen atoms to form a trigoanl pyramidal SnO3 or four oxygen atoms to form a square pyramidal SnO4, and a phosphorus atom will link with four oxygen atoms to form a tetrahedron PO4. Either SnO3 or SnO4 units connect with PO4 by common vertex to form the anion structures ranging from isolated anions to infinite chains, two-dimensional layers, and three-dimensional extended networks. The organic amines could act as a structure-directing agent, or merely fill the available voids and stabilize the structures through hydrogen bonding and other interactions. In this paper, we report the synthesis and crystal structure of a new three-dimensional open-framework tin(II) phosphate, [H2DACO]0.5[Sn4(PO4)3], having a Sn:P ratio of 4:3, prepared under hydrothermal conditions in the presence of 1,5-diazacyclooctane (DACO) as the structure-directing agent.

H2NiTi4O10/TiO2 intercalated compound was fabricated by successive intercalation reactions of H2NiTi4O10 with n-C6H13NH2/C2H5OH mixed solution and acid TiO2 sol, followed by irradiating with a high-pressure mercury lamp. H2NiTi4O10, a layered perovskite type compound with TiO2-loading, exhibited a high activity for decomposition of methyl orange under UV and visible light irradiation. The experimental results showed that methyl orange was degraded with the decomposition ratio of 59.0 % by using H2NiTi4O10/TiO2 as photocatalyst under visible light ( > 420 nm) irradiation for 24 h. The H2NiTi4O10/TiO2 possessed higher photocatalytic activity than those commercial titania powder (Degussa P-25) which showed the decomposition ratio just only 24% under same condition.
