Tunable dye-doped xerogel lasers

Conference on Lasers and Electro-Optics Europe, 1994
The easiest route to produce tunable optical pulses is to use a broadband fluorescent gain medium. For this purpose organic dye molecules are very suitable and have been widely used in solution during the past 30 years. Today, new crystals such as titanium sapphire, and nonlinear techniques such as optical parametric oscillation, may provide solid ...

Structural characterization of silica xerogels

Journal of Non-Crystalline Solids, 1995
The structure of silica xerogels prepared following a fully inorganic route was investigated by means of the concurrent use of gas-adsorption, solid-state nuclear magnetic resonance and neutron diffraction techniques. Such an approach enables consistent estimates for the particle and pore sizes to be derived which show the existence of microporous ...

Thermal stability of xerogel films

Thin Solid Films, 2001
In this work, we have investigated the thermal stability of the organic component of porous SiO2 (xerogel) films using a combination of ion beam techniques and thermal desorption spectroscopy (TDS). Ion beam techniques reveal a large concentration of carbon and hydrogen atoms in this film.

"Imitative" click chemistry to form a sticking xerogel for the portable therapy of bacteria-infected wounds.

Biomaterials Science, 2019
Xerogels usually possess a stable structure and have a low swelling rate due to their inferior dynamics. Herein, a xerogel was synthesized by "imitative" click chemistry based on lipoic acid for picking up bacteria from wound sites, and thus accelerating

Mechanical Properties of Silica Xerogels

Journal of the American Ceramic Society, 1991
Strengths have been measured for silica xerogels using four‐point bending. The silica xerogels studied are microporous with open porosity of 53 vol%. Strengths were measured on fresh samples, samples which had been outgassed at 250°C, samples which were exposed to ambient conditions for 2 d, and samples stored in ethanol.

Which is the most effective pristine graphene electrode for energy storage devices: aerogel or xerogel?

Nanoscale, 2019
The morphological design of graphene materials is definitely important since their electrochemical properties as an electrode in energy storage devices are mainly dominated by their charge accessibility and active area.
