A thermolytic route to a polysilyne.

Despite these differences, this soluble, yellow polysilyne exhibits some important properties associated with the traditional random network structure: it absorbs up to 400 nm in the UV spectrum, yet is stable to photolysis under inert atmosphere.

Fabrication of Silicon Carbide from Vietnamese Rice Husk Charcoal and Diatomite by Electric Arc Furnaces

Silicon carbide (SiC) was synthesized from Vietnamese rice husk and diatomite by electric arc discharge furnace with the arc current of 100, 150, and 200 A. The synthesized products were

Differential-Scanning Calorimetry of Anthracite, Graphite, and Calcium Salts

It was established that a shift of equilibrium in the graphite–calcium oxide system toward the formation of calcium carbide can be observed at a temperature of 900°C due to the formation of a

Correlations between photocatalytic activity and chemical structure in copper doped TiO2-SiO2 with Cu2+ sites

Copper modified TiO2-SiO2 photocatalysts were prepared by sol-gel method based on organic Cu, Si and Ti sources. Cu concentration varied from 0.1 to 3 mol%. The photocatalytic activity of the Cu

Facile Synthesis of SiO2 From Poly(silyne-co-hydridocarbyne) Preceramic Precursor

Pre-ceramic polymers have previously been known as polymeric precursors that can be converted to silicon carbide, diamond and diamond-like carbon upon heating at ambient inert atmosphere. Here, we

This study presents a method for high temperature stabilization of amorphous alumina. The strain‐induced stabilization is obtained by dispersion of rigid globular polycarbosilane macromolecules

Physics based analytical model for silicon carbide MESFET for microwave frequency applications

In this paper, we present a physics based analytical modeling and simulation of ion implanted silicon carbide Schottky gate FET. The model has been developed to compute the drain-source current,

Synthesis of Poly(silyne-co-hydridocarbyne) for Silicon Carbide Production

Pre-ceramic polymers have previously been shown to be polymeric precursors to silicon carbide, diamond and diamond-like carbon. Here, we report the synthesis of a pre-ceramic polymer,



Processing, Fracture Toughness, and Vickers Hardness of Allylhydridopolycarbosilane‐Derived Silicon Carbide

Bulk specimens of precursor-derived silicon carbide (SiC) suitable for mechanical-property measurements were prepared from allylhydridopolycarbosilane (AHPCS), which is a commercially available,

Thermal and Photochemical Conversion of Poly(methylsilane) to Poly(carbosilane)

An increase in the ceramic yields for irradiated polymers was observed, parallel to a drastic decrease in the soluble polymer synthetic yield, when the polymer irradiation was performed in the presence of AIBN.

Investigation of the Pyrolytic Conversion of Poly(silylenemethylene) to Silicon Carbide

The pyrolysis of poly(silylenemethylene) (PSE), [SiH2CH2]n, a linear polycarbosilane with a regularly alternating Si−C backbone structure and a high-yield precursor to stoichiometric SiC, was

Sonochemical Synthesis of a Poly(methylsilane), a Precursor for Near-Stoichiometric SiC

We report a sonochemical process for a single-pot synthesis of high molecular weight poly(methylsilane) (PMS) of composition [(CH3SiH)x(CH3Si)y(CH3SiH2)z]n, where x + y + z = 1 and 0.65 ≥ (x + z) ≥
