Hydrometallurgy is considered a promising method to produce solar-grade silicon (SOG-Si)
from metallurgical-grade silicon (MG-Si) due to its advantages of low cost, simple operation …

Porous silicon has been established as an excellent sensing platform for the optical
detection of hazardous chemicals and biomolecular interactions such as DNA hybridization …

We report a chemical route to colloidal silicon (Si) nanocrystals, or quantum dots, with widely
tunable average diameter, from less than 3 nm up to 90 nm and peak photoluminescence …

Silicon (Si) has been considered as one of the most promising candidates for the next-
generation lithium-ion battery (LIB) anode materials owing to its huge theoretical specific …

This review outlines the developments and recent progress in metal-assisted chemical
etching of silicon, summarizing a variety of fundamental and innovative processes and …

We present a methodology to fabricate one-dimensional porous silicon (PSi) photonic
crystals in the visible range by controlled etching and monitored by photoacoustics …

Metal-assisted etching is initiated by hole injection from an oxidant catalyzed by a metal
nanoparticle or film on a Si surface. It is shown that the electronic structure of the metal/Si …

Fluorine is the most reactive elements among the halogen group and commonly and
ubiquitously occurs as fluoride in nature. The industrial processes produce fluoride by …

Because of its biocompatibility and ability to accommodate a variety of payloads from poorly
soluble drugs to biomolecules, porous silicon (PSi) is a lucrative material for the …

In this study, the influence of n-type porous Si (n-PS) morphology properties and the
performance of Ag nanoparticles (AgNPs)/n-PS Raman substrate were investigated. Two …
