General description

Methanol is a polar solvent and feedstock to produce chemicals and fuel additives. It can be produced through the catalytic hydrogenation of CO2.

Application

Methanol can be used as a solvent in the:
  • Palladium(II)-exchanged hydroxyapatite-catalyzed Suzuki–Miyaura cross-coupling reactions.
  • Reductive amination of ketones with ammonia and dihydrogen to synthesize primary amines.

Macrophages populate the steady-state myocardium. Previously, all macrophages were thought to arise from monocytes; however, it emerged that, in several organs, tissue-resident macrophages may self-maintain through local proliferation. Our aim was to study the contribution of monocytes to cardiac-resident macrophages
