FASTENING: A new series of Corrosion-Resistant Pull-Down Latches from All Metric Small Parts (aMsp) is designed for various types of boxes and transportation equipment. Because springs are used, a tightening force is applied when the latch is closed. Since the latch is made of stainless steel it has excellent corrosion resistance. The holes for a padlock are on the side, preserving the appearance even when there is no lock. 3-D CAD models are available for download.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
