Laser-etched snake-inspired material reduces friction by 40%

A snake skin inspired surface, manufactured using laser etching, has smashed records by providing a 40 per cent friction reduction in tests of high performance materials. A paper discussing this finding is published today (1 June 2015) in IOP Publishing’s Bioinspiration & Biomimetics journal.

Lead researcher, Dr Christian Greiner and his team used a laser to etch the surface of a steel pin so that it closely resembled the texture of snake skin. They then tested the friction created when the pin moved against another surface.

The best thing since sliced bread

Perten Instruments has announced that a new method for determining bread volume was approved by the American Association of Cereal Chemists – International (AACCI). The method was assessed by a collaborative study conducted by the AACCI Physical Testing Methods Technical Committee and demonstrated acceptable precision for samples with volumes ranging from 200 to 2,800mL. Results were similar to volumes determined by reference water displacement analysis.
