General description

Thermochemical conversion of methanol to C2-C10 hydrocarbons in the presence of shape-selective zeolites has been reported. Its oxidation on Ru-Pt catalyst system by ruthenium ad-atoms has been proposed.

Application

Used as a solvent in:
  • Preparation of self-assembled monolayers (SAMs) of sulfur derivatives with bactericidal terminal fragments on gold surfaces prior to analytical characterization
  • Measurement of soluble absorption spectra of PTFE samples

Packaging

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
