Two-armed 3-D printing

Twin robotic arms work together as part of a project to construct what will be the largest, most complex object ever 3-D printed in titanium: a test version of the 3-m diameter 'optic bench' at the heart of ESA's Athena X-ray ...

Using an organocatalyst to stereocontrol polymerization

A pair of researchers at the University of North Carolina has developed a way to use an organocatalyst to stereocontrol polymerization. In their paper published in the journal Science, A. J. Teator and F. A. Leibfarth describe ...

Robot arms with the flexibility of an elephant's trunk

Unlike conventional robot arms with hinged and swivel joints, new flexible arms being developed by Professor Stefan Seelecke and his research group at Saarland University are constructed using muscles made from shape-memory ...

New method opens the way for cutting tools with longer lifetime

Researchers at Linköping University, LiU, have developed a theoretical model that enables simulations for showing what happens in hard cutting materials as they degrade. The model will enable manufacturing industries to ...

Beaches are banning sunscreens to save coral reefs

Many families will soon escape the winter to seek warmer, sunnier climes. Swimsuits and sunglasses will invariably find their way into suitcases, but one common item might be giving people a little more pause than it once ...
