Iron oxide nanoparticles becoming tools for brain tumor imaging and treatment

Tiny particles of iron oxide could become tools for simultaneous tumor imaging and treatment, because of their magnetic properties and toxic effects against brain cancer cells. In mice, researchers have demonstrated how these particles can deliver antibodies to implanted brain tumors, while enhancing tumor visibility via magnetic resonance imaging (MRI).

New solar energy conversion process could revamp solar power production

A new process that simultaneously combines the light and heat of solar radiation to generate electricity could offer more than double the efficiency of existing solar cell technology. The process, called 'photon enhanced thermionic emission', or PETE, could reduce the costs of solar energy production enough for it to compete with oil as an energy source.

Hydrogen causes metal to break

Hydrogen is considered the fuel of the future. Yet this lightest of the chemical elements can embrittle the metals used in vehicle engineering. The result: components suddenly malfunction and break. A new special laboratory is aiding researchers' search for hydrogen-compatible metals.

Nanoparticle-coated pavement that cleans the air

The concentrations of toxic nitrogen oxide that are present in German cities regularly exceed the maximum permitted levels. That's now about to change, as innovative paving slabs that will help protect the environment are being introduced. Coated in titanium dioxide nanoparticles, they reduce the amount of nitrogen oxide in the air.
