A method for alleviating the effect of pinhole defects from silicon nitride film in n-type rear-junction PERT silicon solar cells

We investigated incorporation of a novel approach of phosphorous silicate glass layer thinning (PGT) process in the N-PERT process flow to minimise pinhole defects at the silicon nitride (Si3N4) surface. The thinning (PGT) process for optimum HF deposi…

Hydrodynamic and transport behavior of solid nanoparticles simulated with dissipative particle dynamics

Hydrodynamic and transport behavior of solid nanoparticles simulated with dissipative particle dynamics

Inertial migration of micro- and nanoparticles flowing through microchannels is commonly used for particle separation, sorting, and focusing on many lab-on-a-chip devices. Computer simulations of inertial migration of nanoparticles by mesoscale simulat…

Synthesis of V2O5-MgO/TiO2 mixed oxide nanocomposites for photocatalytic treatment of CO in vehicle exhaust emissions

Photocatalytic nanotechnology is one of the techniques that brings many new breakthroughs since it possesses high potential for the supply of clean energy and the degradation of persistent organic pollutants in the environment. The drawback of photocat…

Surface modification of PVA/Chitosan/PEG/HAp nanofiber scaffolds by plasma treatment and studies of their morphology, wettability, and biodegradation rate

Surface modification of PVA/Chitosan/PEG/HAp nanofiber scaffolds by plasma treatment and studies of their morphology, wettability, and biodegradation rate

Nanofiber scaffold has been widely developed as a tissue engineering material because it can imitate the ECM of bones. In this study, nanofiber scaffold is composed of polyvinyl alcohol (PVA), chitosan, polyethylene glycol (PEG), and hydroxyapatite (HA…

Chitosan and Aloe Vera decorated nanoparticulate system loaded with Minoxidil as a suggested topical formulation for alopecia therapy

Chitosan and Aloe Vera decorated nanoparticulate system loaded with Minoxidil as a suggested topical formulation for alopecia therapy

Minoxidil (Mxd) is a common medication used for hair regrowth in patients exhibiting different types of alopecia, especially androgenetic alopecia (AGA), but it has some negative aspects such as causing adverse effects and having limited permeation thr…

Enhanced ferroelectric and ferromagnetic properties of xNiFe2O4/(1–x)Ba0.94Ca0.06Ti0.975Zr0.025O3 nanocomposites

Enhanced ferroelectric and ferromagnetic properties of xNiFe2O4/(1–x)Ba0.94Ca0.06Ti0.975Zr0.025O3 nanocomposites

Bi-phase multiferroic composites of NiFe2O4/Ba0.94Ca0.06Ti0.975Zr0.025O3 (BCTZ/NFO) were successfully fabricated by high-energy ball milling combined with heat treatment. X-ray diffraction patterns and Raman spectra confirmed the successful coexistence…
