2 There has been a wealth of recent interest in proteomics, which involves the global analysis of protein expression and function. Identification of complex protein mixtures is a difficult process that can first involve, for example, two-dimensional gel electrophoresis to resolve individual proteins. These separated proteins can then be hydrolysed with enzymes such as trypsin to their constitue...

The ruthenium-catalyzed generation of hydrogen from formic acid is significantly accelerated by light.

Formic acid is the sole carbon and hydrogen source in additive-free catalytic methylation of amines.

We present a detailed budget of formic and acetic acids, two of the most abundant trace gases in the atmosphere. Our bottom-up estimate of the global source of formic and acetic acids are ∼1200 and ∼1400 Gmol yr−1, dominated by photochemical oxidation of biogenic volatile organic compounds, in particular isoprene. Their sinks are dominated by wet and dry deposition. We use the GEOS-Chem chemica...

A specialized vacuum electrolysis reactor was designed, constructed, and utilized for 13-carbon isotope analysis of formic acid-13C and acetic acid-13C, each highly enriched at the C1-position. This reusable reactor was equipped with two platinum wire electrodes, miniature stir bar, and sidearm reaction chamber. The associated technique developed for 13-carbon isotope analysis is based upon ele...

Biodegradation is competitive with photochemistry, especially in summer and at night. Formic acid the most impacted compound.

Concentration differences between small (r < 8.5 μm) and large droplets (r > 8.5 μm) were observed for formic acid, acetic acid and formaldehyde in fog droplets collected in California’s Central Valley. The concentration ratios (large/small droplets) of these compounds were investigated by a stepwise model approach. Assuming thermodynamic equilibrium (KH) results in an overestimate of the conce...
