ETFuels has selected John Cockerill and Johnson Matthey (JM) to support the development of its 120,000 tonnes per year e-methanol project in Texas. For the front-end engineering design (FEED) phase, ...

Big cars might make you feel safer — but how does vehicle size affect others in a crash? The sun is about to enter its “battle zone”: a phenomenon that worries scientists I've been on 70 ...

Strongly enhanced NMR signals from iridium hydride complexes report on a ligand ... (17) In conclusion, we demonstrated that the nanoscale dispersion in a CTAB/chloroform/heptane reverse micelle ...

Immunosuppressive agents are a significant class of clinical drugs for organic transplantation and treatment of autoimmune diseases, such as rheumatoid arthritis, systemic lupus, multiple sclerosis, ...

Methylation was stopped by adding water (4 mL), and then chloroform (3 mL) was added. The contents of the vial were mixed ... The hydrolyzed sample was mixed with NaBH 4 in water (33 mg/mL; 1 mL) and ...

Instead of using methanol/H 2 O (7/3, v/v) solution for precipitation, pyridine/H 2 O (1/3, v/v) was applied. Similar results were obtained using this procedure.
