Macroscopic Cutting of Aerogel Collectors for Stardust and Future Sample Return Missions
Introduction: Silica aerogel is an ultra-lowdensity glass foam used in collector tiles for the capture of particles in low Earth orbit [1] and, recently, for the capture of cometary particles by NASA’s Stardust mission [2]. Reliable and reproducible methods for cutting these and future collector tiles from sample return missions are necessary to enable detailed study of the captured material. T...

متن کاملPreparation and Characterization of Silica Aerogel Microspheres
Silica aerogel microspheres based on alkali silica sol were synthesized using the emulsion method. The experimental results revealed that the silica aerogel microspheres (4-20 µm in diameter) were mesoporous solids with an average pore diameter ranging from 6 to 35 nm. The tapping densities and specific surface areas of the aerogel microspheres are in the range of 0.112-0.287 g/cm³ and 207.5-66...
متن کاملStudy on diffusion coefficient of benzene and ethyl benzene vapours in nanoporous silica aerogel and silica aerogel-activated carbon composites
In this study, nanoporous silica aerogel and silica aerogel-activated carbon composites have been synthesized using a water glass precursor by cost effective ambient pressure drying method. Equilibrium and kinetics of benzene and ethyl benzene adsorption on silica aerogel and its composites have been measured in a batch mode at tree weights of adsorbent. For the first time, the experimental dat...
متن کاملOptical shock waves in silica aerogel.
Silica aerogels are materials well suited for high power nonlinear optical applications. In such regime, the non-trivial thermal properties may give rise to the generation of optical shock waves, which are also affected by the structural disorder due to the porous solid-state gel. Here we report on an experimental investigation in terms of beam waist and input power, and identify various regime...
