Influence of temperature and time on the Eu3+ reaction with synthetic Na-Mica-n (n = 2 and 4) [PDF]
, 2016 Bentonite is accepted as the best clay material for the engineered barrier of Deep Geological Repositories (DGRs). The performance of clay as the main component of the engineered barrier in the DGR has been intensively studied and the structure of the ...

The wind of the M-type AGB star RT Virginis probed by VLTI/MIDI [PDF]
, 2013 We study the circumstellar environment of the M-type AGB star RT Vir using mid-infrared high spatial resolution observations from the ESO-VLTI focal instrument MIDI. The aim of this study is to provide observational constraints on theoretical prediction that the winds of M-type AGB objects can be driven by photon scattering on iron-free silicate grains

Effect of lattice shrinking on the migration of water within zeolite LTA [PDF]
, 2019 Water adsorption within zeolites of the Linde Type A (LTA) structure plays an important role in processes of water removal from solvents. For this purpose, knowing in which adsorption sites water is preferably found is of interest. In this paper, the distribution of water within LTA is investigated in several aluminum-substituted frameworks ranging ...

The Limiting Effects of Dust in Brown Dwarf Model Atmospheres [PDF]
Astrophys.J.556:357,2001, 2001 We present opacity sampling model atmospheres, synthetic spectra and colors for brown dwarfs and very low mass stars in two limiting case of dust grain formation: 1) inefficient gravitational settling i.e. the dust is distributed according to the chemical equilibrium predictions, 2) efficient gravitational settling i.e.

Comet dust as a mixture of aggregates and solid particles: model consistent with ground-based and space-mission results [PDF]
, 2009 The most successful model of comet dust presents comet particles as aggregates of submicron grains. It qualitatively explains the spectral and angular change in the comet brightness and polarization and is consistent with the thermal infrared data and ...

Enabling Highly Efficient Solar Thermal Generation with 800°C-Stable Transparent Refractory Aerogels [PDF]
arXiv, 2021 Although spectrally selective materials play a key role in existing and emerging solar thermal technologies, temperature-related degradation currently limits their use to below 700C in vacuum, and even lower temperatures in air. Here we demonstrate a solar-transparent refractory aerogel that offers stable performance up to 800C in air, which is ...
