Demo of an all-silicon reciprocating heat engine with a volume of less than half a cubic Micron

Arxiv- Piezoresistive heat engine and refrigerator made smaller than half a cubic micron. (H/T MIT Technology Review blog Heat engines provide most of our mechanical power and are essential for long-range transportation. However, whereas significant progress has been made in the miniaturization of motors driven by electrostatic forces, it has proven difficult to reduce the …

Improved Cooling for 3D Microchips With Signicant 3D Chip Deployment Expected 2015-2020

CMOSAIC (European Project) could boost the computing performance of central processors by a factor 10 while consuming less energy. 3D microprocessors cooled from the inside through channels as thin as a human hair filled with a liquid coolant. Such is the solution currently being developed by researchers from the EPFL (Ecole polytechnique fédérale de Lausanne, …

Atomic Map of Quantum Dots Will Enable Guided Atom by Atom Manipulation of Properties

An atomic-scale map of the interface between an atomic dot and its substrate. Each peak represents a single atom. The map, made with high-intensity X-rays, is a slice through a vertical cross-section of the dot. University of Michigan physicists have created the first atomic-scale maps of quantum dots, a major step toward the goal of …
