Nanotechnology provides tools to clean up oil spills

Nanotechnology provides tools to clean up oil spills
Oceanic oil spills are tough to clean up. They dye feathers a syrupy sepia and tan fish eggs a toxic tint. The more turbulent the waters, the farther the slick spreads, with inky droplets descending into the briny deep. Now technology may be able to succeed where hard-working volunteers have failed in the past. Researchers at the A*STAR IBN are using nanoscience to turn an oil spill into a floating mass of brown jelly that can be scooped up before it can make its way into the food chain.

Graphene's conduction could transform waste heat in power

Graphene's conduction could transform waste heat in power
A*STAR researchers have found a simple way to vary the heat flow in graphene, a breakthrough that will improve attempts to put superfluous heat in electronics to good use. Graphene has an extraordinarily high thermal conductivity. Liu Xiangjun from the A*STAR Institute of High Performance Computing and co-workers have developed a way to decrease graphene's thermal conductivity, enabling excess heat to be diverted toward components that can dissipate it or even turn it into electricity.

Assembling photovoltaic components from inexpensive metals

Assembling photovoltaic components from inexpensive metals
By rapidly heating silicon wafers covered with thin iron silicide and aluminum films, A*STAR researchers have developed a way to eliminate many of the complicated, time-consuming steps needed to fabricate light harvesting solar cells. Silicon photovoltaic devices typically sandwich two semiconductor layers containing positively or negatively charged impurity atoms, or dopants, into a so-called p-n junction.
