Most biofuels are not 'green', researchers show

(Phys.org)—First tops, then flops. That is one way of summing up the history of biofuels so far. A new study led by Empa gives an up-to-date picture of the ecobalance of various biofuels and their production processes. ...

Same fungus, different strains

Fungi play key roles in nature and are valued for their great importance in industry. Consider citric acid, a key additive in several foods and pharmaceuticals produced on a large-scale basis for decades with the help of ...

One transistor for all purposes

In mobiles, fridges, planes – transistors are everywhere. But they often operate only within a restricted current range. LMU physicists have now developed an organic transistor that functions perfectly under both low and ...

Promising new solar-powered path to hydrogen fuel production

Engineers at Lehigh University are the first to utilize a single enzyme biomineralization process to create a catalyst that uses the energy of captured sunlight to split water molecules to produce hydrogen. The synthesis ...

Helper cells aptly named in battle with invading pathogens

By tracking the previously unknown movements of a set of specialized cells, Whitehead Institute scientists are shedding new light on how the immune system mounts a successful defense against hostile, ever-changing invaders.

Aluminum alloy manufacturing now 50% more energy efficient

Lighter vehicles can travel farther on less energy, driving demand for lighter automotive components. High-performance aluminum alloys, such as alloy 7075, are among the lightest and strongest options, but they require energy-intensive ...

The holy grail of nanowire production

Nanowires have the potential to revolutionize the technology around us. Measuring just 5-100 nanometers in diameter (a nanometer is a millionth of a millimeter), these tiny, needle-shaped crystalline structures can alter ...
