Cobalt oxide mesoporous nanospheres
19 Sep 2014

Full Text:

To attack the problem of both mechanical and chemical degradation in lithium-ion batteries, a team of researchers at Rensselaer Polytechnic Institute designed and developed an electrode from cobalt oxide mesoporous nanospheres. Shaped like tiny soccer balls with holes scattered across their surface, the hollow spheres suffer severe mechanical and chemical degradation and lose most of their energy storage capability. However, the research team discovered that, after many charge-discharge cycles, the hollow nanospheres are refined, reactivated, and eventually demonstrate unprecedented performance for a battery.

Dust Storm Off Libya
Dust Storm Off Libya
19 Sep 2014
A plume of dust blew from Libya over the Gulf of Sidra in late September, 2014. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite captured this true-color image on September 14, 2014.

The dust appears to rise from south of the Jebel Akhdar (the Green Mountain) in northeast Libya. The Jebel Akhdar is one of the few forested areas in Libya and the wettest part. South of this green area, and away from the coast, Libya’s land mainly consists of arid sand seas. Only about 1 percent of Libya’s land is arable, and dust storms rank among the country’s leading natural hazards.
