A corona discharge is used to create and store negative charge in the silicon nitride films of silicon dioxide/silicon nitride stacks. Effective lifetime measurements on both textured and planar, as well as both boron diffused and undiffused silicon samples passivated with silicon oxide/silicon nitride stacks, show that the creation of negative charge in the nitride layer results in an improvem...

In-depth understanding of the retarded oxidation phenomenon observed during the oxidation of silicon nanostructures is proposed. The wet thermal oxidation of various silicon nanostructures such as nanobeams, concave/convex nanorings, and nanowires exhibits an extremely different and complex behavior. Such effects have been investigated by the modeling of the mechanical stress generated during t...

Magnesium-based alloys were more prevalent in automobile applications owing to their mechanical properties, low mass, and density. However, its poor properties are restricting applications. Therefore, the present study focuses on improving of AZ31D alloy by reinforcing silicon carbide (SiC) graphite (Gr) nanoparticles with weight fractions 2%, 4%, 6% using stir-casting technique. The microstruc...

Different porous silicon (PS) layers were impregnated with rhodamine 6G (Rh) solution in order to form Rh/PS nanocomposites. The effect of the porous matrix (fresh, oxidised, type p) on the propriety of photoluminescence (PL) has been investigated. It was found that the luminescence of this nanocomposite is provided by an energy transfer from PS nanocristallites to rhodamine and from interactio...

a r t i c l e i n f o The composite film of carbon nanotubes and silicon carbide nanowires was synthesized directly on the silicon substrate by the catalyst-assisted method. The carbon nanotubes crimped together decorated with silicon carbide nanowires covering the whole substrate. The appropriate amount of aluminum powders is a crucial factor to achieve the composite film. The composite film e...

Sustainable food packaging films were developed using a combination of k-Carrageenan (k-C), hydroxyl ethyl cellulose (HEC), silicon dioxide (SiO2), and silver (Ag) nanoparticles. The CH-SiO2/Ag nanocomposites showed promising results, mainly due to their transparency, flexibility, low cost, environmental friendliness. structure uniform morphology the determined by FT-IR, XRD, SEM analysis.

Direct air capture is regarded as a plausible alternate approach that, if economically practical, can mitigate the increasing carbon dioxide emissions associated with two of the main carbon polluting sources, namely stationary power plants and transportation. Here we show that metal-organic framework crystal chemistry permits the construction of an isostructural metal-organic framework (SIFSIX-...
