The conversion of preceramic polymers to ceramics normally requires multiple processing steps such as curing, pyrolysis, and crystallization, which can be time energy-consuming. Herein, one-step rapid synthesis cubic silicon carbide (β-SiC) by laser-assisted pyrolysis crystallization molten polycarbosilane (PCS) is shown. resulting product termed “LISiC” (laser-induced carbide). It demonstrated...

The present work is a review of the substantial effort that has been made to measure and understand the effects of corrosion with respect to the properties, performance, and durability of various forms of silicon carbide and silicon nitride. The review encompasses corrosion in diverse environments, usually at temperatures of 1000 °C or higher. The environments include dry and moist oxygen, mixt...

The composite group investigates endlessly the features of natural fiber/thermoplastic matrix materials to improve recyclability, use renewable sources, and reduce material costs. In this context, development biodegradable polymers for composites is considered one important strategies reducing environmental challenges. Here, axially oriented fibers incorporated in conforming matrices make up fi...

The conversion of palm oil into a sulfur-based polymer by copolymerization with sulfur powder at its molten state is herein reported. obtained sulfur-containing was characterized using Fourier transform infrared (FTIR), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC) to demonstrate the successful conversion. disappearance peaks related vinylic groups together appea...

Wire arc additive manufacturing (WAAM) technique is a cost-competitive and efficient technology to produce large structure components in industry domains. Mechanical properties are mainly dominated by the microstructure of the components, which is deeply affected by the molten pool size. In this work, to investigate the effect of the molten pool size on microstructure and mechanical properties ...

The ability to design and synthesize polymers that can perform functions with great speci"city would impact advanced technologies in important ways. Biological macromolecules can self-assemble into motifs that allow them to perform very speci"c functions. Thus, in recent years, attention has been directed toward elucidating strategies that would allow synthetic polymers to perform biomimetic fu...
