In this study, we investigated the influence of the addition of carbon materials on the heat resistance and flame retardancy of silica xerogels. A mixed dispersion prepared by adding 0.1 to 2.5 wt% each of the carbon materials, graphene oxide (GO), p

The aerogel composite insulation sheet which is complexed with fibers such as non-woven fabric and aerogel has been launched. However, it is one of the biggest problems for practical use that the insulation material has low strength and low rigidity

Carbon (δ13C) and oxygen (δ18O) isotope composition of Rhynchonelliformea brachiopods (hereafter, called ‘brachiopods’) have been regarded as useful paleoenvironmental indicators throughout the Phanerozoic. However, recent studies have revealed

The Late Devonian biodiversity crisis, one of the big five Phanerozoic diversity depletions, is composed of a series of extinction events broadly coincident with the invasion of land by plants and vertebrates. These extinctions may have been triggere

Liquid Crystals XI.
Here we show the simple fabrication of field effect transistor (FET) with a mesophase semiconductor, a derivative of dithienyl naphthalene, which exhibits a fast mobility (10 -1 ~ 10 -2 cm 2 V -1 s -1 ) of charged carriers in the mesophase. The compo

Recent studies on transistors fabricated with liquid crystalline semiconductors with high solubility in common organic solvents have shown the characteristic features provided by their “mesomorphic properties”. In particular, calamitic liquid cry
