Frontiers in Astronomy and Space Sciences, 2021 The issue of formation of dust grains in the interstellar medium is still a matter of debate. One of the most developed proposals suggests that atomic and heteromolecular seeds bind together to initiate a nucleation process leading to the formation of ...

EFFECT OF FOLIAR APPLICATIONS OF SALICYLIC ACID AND POTASSIUM SILICATE ON TOLERANCE OF WHEAT PLANTS TO SOIL SALINITY [PDF]
Journal of Soil Sciences and Agricultural Engineering, 2013 A pot experiment was carried out under greenhouse conditions to investigate the effect of salicylic acid (SA) and potassium silicate (KSi) foliar applications in alleviating the salt stress of soil salinity (S) on wheat plants. Three soil salinity

ÆSOPUS 2.0: Low-temperature Opacities with Solid Grains
The Astrophysical Journal, 2023 In this study we compute the equation of state and Rosseland mean opacity from temperatures of T ≃ 30,000 K down to T ≃ 400 K, pushing the capabilities of the Æ SOPUS code into the regime where solid grains can form.

Quartz dissolution associated with magnesium silicate hydrate cement precipitation [PDF]
Solid Earth, 2021 Quartz has been replaced by magnesium silicate hydrate cement at the Feragen ultramafic body in south-east Norway. This occurs in deformed and recrystallized quartz grains deposited as glacial till covering part of the ultramafic body.

An experimental investigation of the condensation of silicate grains [PDF]
The Astrophysical Journal, 1978 Amorphous magnesium silicate smoke particles were condensed from hydrogen and argon atmospheres containing Mg and Si0. A wide range of initial compositions were observed but all particles could be recrystallized into forsterite (Mg2Si04), by heating to 1000 C in vacuum.
