Flexible paper-like semiconductor nanowire materials are expected to meet the criteria for some emerging applications, such as components of flexible solar cells, electrical batteries, supercapacitors, nanocomposites, bendable or wearable electronic or optoelectronic components, and so on. As a new generation of wide-bandgap semiconductors and reinforcements in composites, SiC nanowires have ad...

This study investigates the effects of the addition of tungsten on the structure, phase composition, textural properties and activities of β-SiC-based catalysts in the aqueous phase hydrogenation of furfural. Carbothermal reduction of SiO₂ in the presence of WO₃ at 1550 °C in argon resulted in the formation of WxC-β-SiC nanocomposite powders with significant variations in particle morphology an...

Stacking various two-dimensional atomic crystals on top of each other is a feasible approach to create unique multilayered heterostructures with desired properties. Herein for the first time, we present a controlled preparation of large-area graphene/MoS2 heterostructures via a simple heating procedure on Mo-oleate complex coated sodium sulfate under N2 atmosphere. Through a direct in situ cata...

The fabrication by Spark Plasma Sintering (SPS) of bulk high entropy ceramics from powders obtained Self-propagating High temperature Synthesis (SHS) is addressed in this work. effect produced the introduction 1 wt.% graphite to before SPS investigated under different conditions. final density and composition sintered (Hf0.2Mo0.2Zr0.2Ti0.2Ta0.2)B2 (Hf0.2Mo0.2Zr0.2Ti0.2Nb0.2)B2 are found be nega...

The object of research is the melting technology a complex titanium-containing ferroalloy by single-stage slagfree carbothermal method using high-ash coals as reducing agent. ilmenite concentrate (Shokash deposit, Aktobe region, Kazakhstan), rich titanium slag, which was obtained scientists Chemical and Metallurgical Institute named after Zh. Abishev (Karaganda, well coal agent were used charge...

The present study aims to synthesize SiAlON-based composites utilizing coal gangue. Different types of SiAlON-based composites were synthesized using coal gangue by carbothermal reduction nitridation method through control of different reaction atmospheres. The experimental results indicate that the oxygen partial pressure was an essential factor in the manufacture of SiAlON-based composites an...
