A step closer to sustainable energy from seawater

The research group led by Leiden chemist Marc Koper has discovered a catalyst that minimizes the production of chlorine gas during salt water electrolysis. The invention can enable the direct production of hydrogen from seawater. ...

Plant cellulose prevents short circuits in batteries

(Phys.org)—In order to prevent short circuits in batteries, porous separator membranes are often placed between a battery's electrodes. There is typically a tradeoff involved, since these separators must simultaneously ...

The heat is on for sodium-manganese oxide rechargeable batteries

(PhysOrg.com) -- By adding the right amount of heat, researchers have developed a method that improves the electrical capacity and recharging lifetime of sodium ion rechargeable batteries, which could be a cheaper alternative ...

Genetically engineered yeast soak up heavy metal pollution

Environmental contamination with heavy metals is often the result of various types of industrial processes. Because heavy metals can be dangerous to humans and other wildlife, contaminated sites need to be cleaned up. This ...

Molecular snapshots of oxygen formation in photosynthesis

Researchers from Umeå University, Sweden, have explored two different ways that allow unprecedented experimental insights into the reaction sequence leading to the formation of oxygen molecules in photosynthesis. The two ...

Progress toward a new flu treatment, thanks to a small tweak

This year's unexpectedly aggressive flu season reminds everyone that although the flu vaccine can reduce the number of people who contract the virus, it is still not 100 percent effective. Researchers report that a tweak ...
