We present high-spatial-resolution (0.7 to 1.0 arcsec) submillimeter observations of continuum and molecular lines of CH3OCHO, CH3OCH3, and H2CCO toward 11 high-mass star-forming regions using the Atacama Large Millimetre/submillimetre Array (ALMA).

Autor: Yamato, Yoshihide, Aikawa, Yuri, Guzmán, Viviana V., Furuya, Kenji, Notsu, Shota, Cataldi, Gianni, Öberg, Karin I., Qi, Chunhua, Law, Charles J., Huang, Jane, Teague, Richard, Gal, Romane Le

Characterizing the chemistry of complex organic molecules (COMs) at the epoch of planet formation provides insights into the chemical evolution of the interstellar medium (ISM) and the origin of organic materials in our Solar System. We report a dete

Liquefied dimethyl ether as alternative extraction solvent for high γ-oryzanol rice bran oil: Systematic HSP theory and experimental evaluation

Autor: Phannipha Daisuk, Seiichi Takami, Masaki Honda, Motonobu Goto, Chonlatep Usaku, Artiwan Shotipruk

Publikováno v: Journal of Bioresources and Bioproducts, Vol 9, Iss 4, Pp 577-591 (2024)

This study aimed to systematically find an alternative solvent to replace hexane for the extraction of bio-oil with high γ-oryzanol content from rice bran (RB). The selection involved predicting solubility through Hansen solubility theory, experimen
