Researchers capture speedy chemical reaction in mid-stride

In synthetic chemistry, making the best possible use of the needed ingredients is key to optimizing high-quality production at the lowest possible cost. The element rhodium is a powerful catalyst -- a driver of chemical reactions -- but is also one of the rarest and most expensive. In addition to its common use in vehicle catalytic converters, rhodium is also used in combination with other metals to efficiently drive a wide range of useful chemical reactions.

New haptic microscope technique allows researchers to 'feel' the microworld

What if you could reach through a microscope to touch and feel the microscopic structures under the lens? In a breakthrough that may usher in a new era in the exploration of the worlds that are a million times smaller than human beings, researchers at Université Pierre et Marie Curie in France have unveiled a new technique that allows microscope users to manipulate samples using a technology known as 'haptic optical tweezers'.

Surface cleaning boosts nanowire solar cell efficiency

Energy losses in nanowire solar cell can be significantly reduced by 'cleaning' the surface of the cells with a special etching method. This has been shown by researchers at Eindhoven University of Technology, Delft University of Technology and Philips. The solar cell has an efficiency of 11.1%, putting it just below the current world record, but it was reached with much less use of material.
