Diffusion of chiral compound filled in the silica aerogel resulted in the non-uniform pitch distribution, which can be anchored by UV-radical polymerisation. The results strongly suggested that the reflection bandwidth could be broadened preferably by adjusting the silica aerogel condensation time, the ...

Recently a commercially attractive ambient pressure production process was developed which will allow broader commercialization of silica-aerogel products. Some aerogel products for insulation applications and their preparation are described. Sound insulation properties including a remarkable absorption in the ...
Nano-aerogel,perfectly combined with flexble substrates like glass biber and ceramic fiber,maximizes the retention of light weight and heat insulation of aerogel and endows aerogel with flexbilty and toughness. Characteristics of aerogel composites: 1:Super long service life: 99% ...
The measurement results show that the proposed technique can quantitatively estimate the density uniformity of aerogels. 展开 关键词: silica aerogel cherenkov ring imaging X-ray radiography refractive index density DOI: 10.1016/j.nima.2012.09.001 被引量: 4 年份: 2013 ...
and 1 mm are produced.This new process offers two main advantages: the ability to create complex resonator geometries and to print thicker devices.The first two resonance modes were successfully identified for three different thicknesses.A maximum quality factor of 4563 achieved for a 1 mm-thick ...
Clusters of Ag and Au have been formed in the bulk of mechanically strong silica-polymer aerogel composite monoliths. For that purpose, base-catalyzed silica hydrogels were washed with a 50% w/w acetone/diisocyanate (di-ISO) solution, and cured at 55°C for 3 days. Unreacted di-ISO soluti...
