Berkeley Lab nanoscale imaging study yields key insights into photo-electrochemical water splitting

Green Car Congress

This technique correlates the material’s morphology to its functionality, and gives insights on the charge transport mechanism, or how the charges move inside the material, at the nanoscale. The researchers used photoconductive atomic force microscopy to map the current at every point of the sample with high spatial resolution.

Study finds megacity traffic soot can reach high altitudes and be transported over long distances, contributing to global warming

Green Car Congress

above sea level) indicated a systematic transport of particle matter from the metropolitan area of La Paz/El Alto to this high altitude station and subsequently to the lower free troposphere. From there, BC can be transported over long distances and exert impact on climate and composition of remote southern hemisphere.

Researchers find two strains of diesel-eating bacteria in Antarctica

Green Car Congress

This insight could potentially inform bioremediation efforts in the region. Pollution from petroleum hydrocarbons such as diesel, which is widely used for heating, transportation and power generation poses a threat to wildlife in Antarctica. An open-access paper on the work appears in the journal Microbial Cell Factories. Habib et al.

New solid polymer electrolyte outperforms Nafion; novel polymer folding

Green Car Congress

Researchers, led by a team from the University of Pennsylvania, have used a polymer-folding mechanism to develop a new and versatile kind of solid polymer electrolyte (SPE) that currently offers proton conductivity faster than Nafion by a factor of 2, the benchmark for fuel cell membranes. —Trigg et al. The study was led by Karen I.
