VALUE-ADDED METHYL ESTERS FROM BIOMASS
As global demand and prices for petroleum-based feedstocks continue to rise, chemists are being challenged to devise
processes that utilize bio-mass-derived feedstocks
In one of the latest developments, Glaus H. Christensen and coworkers at the Technical University of
Denmark, in Lyngby, have come up with a procedure for the selective oxidation of furfural and hydroxymethylfurfural to form their respective methyl esters (ChemSusChem,
ALTERNATIVE PATHWAY FOR ALCOHOL BIOFUELS
In an effort to advance biofuels, UCLA chemical engineers James G. Liao, Shota Atsumi, and Taizo Hanai have engineered
Escherichia coli to produce
CORROSION-RESISTANT ZEOLITE COATINGS
Zeolite films are well-known as molecular sieves for membrane applications, but they may also be useful as nontoxic,
corrosion-resistant coatings to replace chromate-based materials, according to Yushan Yan and colleagues at the University of California, Riverside (Angew. Chem. Int. Ed, 2008, 47, 525). Hydrothermal zeolite coating methods require high process pressures, which the authors say are difficult for the surface-finishing industry to adopt commercially. To make the coatings at ambient pressure, Yan and coworkers adapted a technique normally used to prepare zeolite powders. Their method relies on an “environmentally benign” ionic liquid solvent rather than water or an organic solvent.
The researchers used the approach to coat a corrosion-susceptible aluminum alloy commonly used in aerospace and defense applications with the silicoaluminophosphate zeolite
