Scientists have discovered that individual atoms can catalyze industrially important chemical reactions such as the hydrogenation of acetylene, offering potentially significant economic and environmental benefits.
Researchers have developed a new technique that allows graphics processing units (GPUs) and central processing units (CPUs) on a single chip to collaborate – boosting processor performance by an average of more than 20 percent.
Engineers have proposed a method of cutting power use and costs in computer processors. Called fine-grained power gating, the method would shut off energy to unused portions of datapath and memory blocks. Current processors fully power all components but rarely are all fully engaged.
Just as a chameleon changes its color to blend in with its environment, engineers have demonstrated for the first time that they can alter the texture of plastics on demand, for example, switching back and forth between a rough surface and a smooth one.
Common material such as polyethylene used in plastic bags could be turned into something far more valuable through a new process.
Graphene could become the next big thing in the quest for smaller, less power-hungry electronics. Physicists are making discoveries that may advance electronic circuit technology.
In chemical industry, heterogeneous catalysis is of crucial iportance to the manufacture of basic or fine chemicals, in catalytic converters of exhaust gas, or for the chemical storage of solar energy. Scientists have now developed a new infrared spectroscopy method in order to study processes at surfaces of oxides used as catalysts.

A new method for creating nanofibers made of proteins promises to greatly improve drug delivery methods, aid in regenerating human tissue, and pave the way to an organic method of building nanofibers for tiny, powerful microprocessors. Researchers have discovered how to make nanofibers using the COMP protein found in human cartilage.
