:mCl Quum INSrnCrnD3 Abstract We have successfully integrated a thermally insulating silica aerogel thin film into a new uncooled monolithic thin film infrared (E) imaging device. Compared to other technologies (bulk ceramic and microbridge), use of an aerogel layer provides superior thermal isolation of the pyroelectric imaging element from the relatively massive heat sinking integrated circui...

Introduction: The Stardust mission brought to earth samples from the comet 81P/ Wild 2. The cometary material is believed to be the most primitive material in the solar system and the return of the samples provides information about the prevailing conditions of the early solar system. The samples have been trapped in silica aerogel at 6.1km.s and the hypervelocity impacts have generated deceler...

Superhydrophobicity and self-cleaning require a combination of surface topography and low-energy surfaces, where mechanical damage of the topography or contamination with oils lead to loss of the nonwetting properties. We show that such vulnerability can be solved by superamphiphobic (i.e., both superhydrophobic and superoleophobic) surfactant-coated aerogel surfaces. Using silica aerogels as m...

The copper(II) complex of 1,4,7,10-tetraazacyclododecane [Cu(II)-cyclen] was covalently immobilized in mesoporous silica aerogel. This immobilization significantly alters the catalytic activity Cu(II)-cyclen when referenced to dissolved oxidation phenol by H2O2 aqueous solution. In order understand this phenomenon, functionalized aerogel characterized scanning electron microscopy (SEM), N2 poro...

We present the results of high magnetic field experiments in pure $^{3}\mathrm{He}$ (in absence $^{4}\mathrm{He}$ coverage) nematic aerogel. In this case aerogel strands are covered with few atomic layers solid paramagnetic $^{3}\mathrm{He}$, which enables spin-exchange mechanism for quasiparticles scattering. Our earlier NMR showed that low fields, instead polar phase, $A$ phase is expected to...

Silica monolith aerogels with different degrees of hydrophobicity by incorporating methyltrimethoxysilane (MTMS) or trimethylethoxysilane (TMES) in standard sol-gel synthesis were prepared. Excellent properties of the aerogels, obtained with the sol-gel synthesis, were preserved with supercritical drying with CO2. The degree of the hydrophobicity of the aerogels was tested by measuring the cont...

Silica-based aerogels bearing a novel aminophosphonate-containing substituent were prepared. Pd2+ and Cu2+ ions introduced into aerogel matrix to form chelated complexes with aminophosphonate moiety. Both securely retain Me2+ after supercritical drying (SCD) in CO2. In silica matrix, Pd complex is reduced metallic treatment by gaseous H2 at 120 °C. lyogel can also be upon SCD isopropanol. Pd-co...
