1.1. Historic Perspective Silica and doped silica materials obtained via the solution− gelation
(“sol− gel”) inorganic polymerization process are functional materials with an impressive …

The increasing demand for “clean” and efficient energy has resulted in an increased global
willingness to embrace the proposed “hydrogen economy” as a potential long term solution …

Recent development in microporous inorganic membranes represents a significant advance
in materials for separation and chemical reaction applications. This paper provides an in …

Mixed matrix membranes (MMMs) were developed by incorporating inorganic silica
nanoparticles into blends of polysulfone/polyimide (PSF/PI) asymmetric membranes for gas …

A Green fluorescent protein (GFP) based whole cell bacterial biosensor was prepared using
a bacterial strain sensitive to several heavy metals in order to detect bioavailable heavy …

Cobalt silica membranes were fabricated using sol–gel techniques for separation of H2 in a
membrane reactor set up for the low temperature (up to 300° C) water gas shift (WGS) …

In this work we describe the preparation of hybrid organic–inorganic films using the sol–gel
process. Poly (ethylene oxide-b-amide-6), PEBAX, was used as an organic matrix. Silicon …

Hybrid silica membranes are of great interest for molecular separation owing to their
outstanding hydrothermal stability. Despite good separation properties in liquid applications …

Membrane technology and deep eutectic solvents (DESs) have demonstrated their efficient
and alterable functionality against environmental pollutants in a cost-effective way. This …

Inorganic silica aerogels derived from sodium silicate are voluminous three-dimensional
open networks with exceptional properties such as a density as low as∼ 100 kg m− 3, high …
