Fertilizer Fizzles If Used In Homemade Bomb

A Sandia engineer who trained U.S. soldiers to avoid improvised explosive devices (IEDs) has developed a fertilizer that helps plants grow but can’t detonate a bomb. It’s an alternative to ammonium nitrate, an agricultural staple that is also the raw ingredient in most of the IEDs in Afghanistan....

Chemical 'Glue' Binds Molecules to Metal Surfaces

An MIT team has developed a method for attaching molecules to metal surfaces. The new approach uses a family of chemicals called carbenes to attach other substances to gold — and potentially to other material surfaces as well. Carbenes could function as “surface anchors” to link many...
