Detection of abundant solid methanol toward young low mass stars [PDF]
, 2003 We present detections of the absorption band at 3.53 micron due to solid methanol toward three low-mass young stellar objects located in the Serpens and Chameleon molecular cloud complexes.

Evaporation and Discharge Dynamics of Highly Charged Multicomponent Droplets Generated by Electrospray Ionization [PDF]
, 2010 We investigate the Rayleigh discharge and evaporation dynamics of highly charged two-component droplets consisting principally of methanol with 2-methoxyethanol, tert-butanol, or m-nitrobenzyl alcohol.

Stevioside methanol tetrasolvate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2013 Stevioside is a naturally occurring diterpenoid glycoside in Stevia rebaudiana Bertoni. The title compound, C38H60O18·4CH3OH, crystallized as its methanol tetrasolvate. Stevioside consists of an aglycone steviol (a tetra-cyclic diterpene in which the four-fused-ring system consists of three six-membered rings and one five-membered ring) and a sugar ...

Selective conversion of CO2 and H2 into aromatics
Nature Communications, 2018 Selective conversion of CO2 and H2 into aromatics remains challenging due to the high unsaturation degree and complex structure of aromatics. Here the authors report a composite catalyst of ZnAlOx and H-ZSM-5 which promotes the formation of aromatics ...

Methanol masers : Reliable tracers of the early stages of high-mass star formation [PDF]
, 2005 The GLIMPSE and MSX surveys have been used to examine the mid-infrared properties of a statistically complete sample of 6.7 GHz methanol masers. The GLIMPSE point sources associated with methanol masers are clearly distinguished from the majority ...

The first high-resolution observations of 37.7-, 38.3- and 38.5-GHz methanol masers [PDF]
, 2018 We have used the Australia Telescope Compact Array (ATCA) to undertake the first high angular resolution observations of 37.7-GHz ($7_{-2} - 8_{-1}E$) methanol masers towards a sample of eleven high-mass star formation regions which host strong 6.7-GHz ...
