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 ...

Team visualizes complex electronic state

A material called sodium manganese dioxide has shown promise for use in electrodes in rechargeable batteries. Now a team of researchers has produced the first detailed visualization—down to the level of individual atoms—of ...

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 ...

Recreating ancient minerals

When it comes to making a lasting impression in geological history, the medium makes all the difference, especially in the Earth's paleo-oceans. Here, during the Archean Eon (4,000-2,500 million years ago) and at times during ...

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 ...

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 ...
