Dissolving platinum speeds up reactions

Platinum is a very useful metal for chemical reactions. It acts as a catalyst, making reactions happen faster without getting used up in the process. Unfortunately, platinum is also rare, so buying enough for large industrial reactions can be very expensive. This problem could soon be solved by dissolving it in gallium. Gallium is also … Continue reading Dissolving platinum speeds up reactions

Tiny crab leads the way in miniature robotics

Miniature robots could solve many problems in the future, from surgery to engineering. But before we can put them to work, we need to figure out a way to control such small machines. The key to this may be found in a tiny remote-controlled crab. Created by engineers at Northwestern University in America, the crab … Continue reading Tiny crab leads the way in miniature robotics
