3D-printed Structures Shrink when Heated

12.01.2018 tribonet 94 Views
Counterintuitive “metamaterial” may enable heat-resistant circuit boards. Almost all solid materials, from rubber and glass to granite and steel, inevitably expand when heated. Only in very rare instances do certain materials buck this thermodynamic trend […]

Predicting the limits of friction on metals

30.10.2017 tribonet 282 Views
Normally, bare metal sliding against bare metal is not a good thing. Friction will destroy pistons in an engine, for example, without lubrication. Sometimes, however, functions require metal on metal contact, such as in headphone jacks or […]
