New spongelike material converts solar energy into steam

The DLS that consists of a carbon foam supporting an exfoliated graphite layer.

MIT has developed a new material structure that generates steam by soaking up the sun. The structure — a layer of graphite flakes and an underlying carbon foam — is a porous, insulating material structure that floats on water. When sunlight hits the structure’s surface, it creates a hotspot in the graphite, drawing water up through the material’s pores, where it evaporates as steam. The brighter the light, the more steam is generated.

Pencil Head Sculptures

All The Write Stuff
For most of us pencil is just a tool used for painting, drawing, or updating checkbooks. But in the hands of Dalton, a Brazilian-born artist who lives in Bridgeport, these ordinary pencils turn into miniature sculptures. He carves sculptures out of the tips of pencils using sewing needle and razor blade. Apart from these he needs very bright light, and there is no use of a magnifying glass in creation of these artistic works.

Carbon nanowires coated with silicon (bottom) produces a material that can store six times as much charge

Lithium ion has become the battery of choice for electric vehicles, driving researchers to improve the technology’s performance, longevity, and reliability. A new type of nanowire electrode developed by materials science and engineering professor Yi Cui at Stanford is a step toward that goal.
