Silicon's effect on sunflowers studied
Vibrant, showy sunflowers are revered worldwide for their beauty and versatility. While many varieties of sunflower are grown specifically for their nutritional benefits, ornamental sunflowers have become standards for commercial growers and everyday gardeners. view more (2008-05-08)
Silicon And Diamond
To make super-durable and strong details it is necessary to use so-called diamond composites, i.e. materials (matrixes) with incorporated tiny diamonds. The matrix is to be durable, strong, wear-proof as well as monolithic by structure ensuring chemical interaction with diamonds. To avoid internal tension this matrix must have physical... view more... (2002-09-23)
Nanowire arrays can detect signals along individual neurons
Opening a whole new interface between nanotechnology and neuroscience, scientists at Harvard University have used slender silicon nanowires to detect, stimulate, and inhibit nerve signals along the axons and dendrites of live mammalian neurons. view more (2006-08-25)
