Worms elevate phosphate levels in grass

Worms are the farmer's main little helpers. They improve soil structure and help the plant obtain nutrients and phosphate. But some worms do a better job than others. Hannah Vos obtained her Ph.D. on research on which worms ...

Nanofibers clean sulfur from fuel

(Phys.org)—Sulfur compounds in petroleum fuels have met their nano-structured match. University of Illinois researchers developed mats of metal oxide nanofibers that scrub sulfur from petroleum-based fuels much more effectively ...

Overcoming a battery's fatal flaw

As renewable energy grows as a power source around the world, one key component still eludes the industry: large-scale, stable, efficient and affordable batteries.

Green hydrogen: 'Rust' as a photoanode and its limits

Hydrogen will be needed in large quantities as an energy carrier and raw material in the energy system of the future. To achieve this, however, hydrogen must be produced in a climate-neutral way, for example through so-called ...

Wax, soap clean up obstacles to better batteries

A little wax and soap can help build electrodes for cheaper lithium ion batteries, according to a study in August 11 issue of Nano Letters. The one-step method will allow battery developers to explore lower-priced alternatives ...

Crystal defect shown to be key to making hollow nanotubes

(PhysOrg.com) -- Scientists have no problem making a menagerie of nanometer-sized objects -- wires, tubes, belts, and even tree-like structures. What they sometimes have been unable to do is explain precisely how those objects ...
