Infrared (IR) spectroscopy is one of the most popular analytical techniques used to
characterize sol–gel silica materials in their different stages. The method represents, in …

The structural evolution of a systematic series of geopolymers derived from metakaolin is
explored. The onset temperature of crystallization, phase composition and densification of …

The present work examines how the gel structure and phase composition of Na-
geopolymers derived from metakaolin with varied Si/Al ratio evolve with exposure to …

Sol–gel spin coating process is used to produce optical filters from SiO2 and TiO2 multi-
layers. By coating the films symmetrically on both sides of the glass substrates, we designed …

Geopolymers are a relatively new class of material that has many broad applications,
including use as a substitute for Ordinary Portland Cement (OPC), use in soil stabilisation …

The ring-opening reaction of epoxide units in an epoxidized natural rubber/titania (ENR-
50/TiO 2) hybrid in the presence of acetic acid was studied using NMR techniques as well as …

As a potential building material, fast-growing wood (such as poplar) is prone to easy
combustion and having poor mechanical properties, which limit its application range. In …

Normal incidence infrared (IR) absorption spectroscopy is often employed for the
characterization of sol–gel materials. For inorganic SiO2 gel films, the main peak at∼ 1070 …

Densification of ZrO2–3 mol.% Y2O3 sol–gel thin films after heating in air at 100° C≤ T≤
1100° C is investigated, with particular emphasis on porosity evaluation. For this purpose …

A previously studied solution chemically derived two layer absorber has been improved by
adding a third layer. Simulations done with a thin film program showed that the optimized …
