(Phys.org) -- Over the past several years, additive manufacturing has become the golden child of process engineering. This is because it allows parts to be made faster, more cheaply and in some cases to be made at all. Now space engineers are looking at additive processing technology as a means for allowing astronauts on extended missions to build their own replacement parts during their trek, rather than relying on carrying tons of spare parts with them. https://phys.org/news/2012-07-nasa-additive-space.html Space Exploration Tue, 24 Jul 2012 08:36:15 EDT news262337752 At the nano level, researchers at Stanford have discovered a new way to weld together meshes of tiny wires. Their work could lead to exciting new electronics and solar applications. To succeed, they called upon plasmonics. https://phys.org/news/2012-02-harnessing-plasmonics-weld-nanowires.html Nanophysics Mon, 06 Feb 2012 09:58:22 EST news247744679
