Compact batteries enhanced by spontaneous silver matrix formations: Scientists use x-rays to map internal atomic transformations and advance promising lithium-based batteries

In a promising lithium-based battery, the formation of a highly conductive silver matrix transforms a material otherwise plagued by low conductivity. To optimize these multi-metallic batteries-and enhance the flow of electricity-scientists needed a way to see where, when, and how these silver, nanoscale "bridges" emerge.

Cheap asphalt provides 'green' carbon capture: Rice University chemists' product aims to enhance natural gas production at sea

The best material to keep carbon dioxide from natural gas wells from fouling the atmosphere may be a derivative of asphalt, according to Rice University scientists.

A scanning electron microscope image shows the fine pores in a carbon material created at Rice University to capture carbon dioxide from production streams at natural gas wellheads. The material sequesters carbon dioxide molecules at normal wellhead pressures and lets them go when the pressure is released.

'Flying carpet' technique uses graphene to deliver one-two punch of anticancer drugs

An international team of researchers has developed a drug delivery technique that utilizes graphene strips as "flying carpets" to deliver two anticancer drugs sequentially to cancer cells, with each drug targeting the distinct part of the cell where it will be most effective. The technique was found to perform better than either drug in isolation when tested in a mouse model targeting a human lung cancer tumor.

Researchers have attached two drugs -- TRAIL and Dox -- onto graphene strips. TRAIL is most effective when delivered to the external membrane of a cancer cell, while Dox is most effective when delivered to the nucleus, so the researchers designed the system to deliver the drugs sequentially, with each drug hitting a cancer cell where it will do the most damage.
