Photosynthesis Helper Protein Discovered

Photosynthesis is less efficient in plants than it could be. Red algae, in contrast, use a slightly different mechanism and are thus more productive. Scientists from Germany's Max Planck Institute of Biochemistry (MPIB) have now identified a helper protein for photosynthesis in red algae.

Efficient IGBTs

Powerex (Youngwood, PA) has introduced IGBTs from 300A/1200V - 800A/1200V in conventional packages, allowing users an easy upgrade path for increased system ratings and/or improved reliability due to the increased allowable operating junction temperature. Applications include motor drives, fuel cells, and wind and solar inverters.

Novel Catalyst Helps Turn Carbon Dioxide Into Fuel

Artificial photosynthesis is the process of converting carbon dioxide gas into useful carbon-based chemicals - most notably fuel or other compounds usually derived from petroleum - as an alternative to extracting them from biomass. An Illinois research team has produced a catalyst that improves the process.

Self-Igniting Fungi Promising for Biomass-Based Fuels

The complete genetic makeup of two heat-loving fungi often found in composts that self-ignite without flame or spark has been decoded by an international team of scientists. Their findings may lead to the faster and greener development of biomass-based fuels, chemicals, and other industrial materials.
