Research Brings Quantum Computing Closer Alexander E. Braun, Senior Editor - 11/10/2008
University of Michigan researchers used lasers to create an arbitrary initialized quantum state of solid-state qbits at rates of ~1 GHz, taking fundamental steps toward qbit programming. The researchers trapped electron spin in a “dark state” in which they can arbitrarily adjust the proportions of 0 and 1 represented by the qbit. More
Magnetism and Nanocrystals Promise Denser Storage, New Devices Alexander E. Braun, Senior Editor - 10/30/2008
When complex materials are reduced to the nanoscopic scale, never before observed electronic transport phenomena can be seen. Researchers at Oak Ridge National Laboratory are striving to gain a fuller understanding of the mechanisms at play, which could lead to new device applications in spin valves, MRAM or photovoltaics.

Spintronics: Poised for Next Great Memory Breakthrough? Stuart Parkin, IBM Almaden Research Center, San Jose - 10/01/2008
Spin-polarized current revolutionized digital storage on disk drives. The next step for spintronics may mean replacing flash memory with magnetic tunnel junction MRAMs. In the meantime, the industry is only beginning to appreciate this alternative state variable, spin.

Researchers Measure Nanomaterials’ Trek Through Food Chain Alexander E. Braun, Senior Editor - 09/16/2008
A NIST study shows that although engineered nanomaterials can climb from the food chain’s lowest rungs — from single-celled organisms to multicelled ones — the actual quantity of nanoparticles transferred is relatively small, and there is no indication that nanomaterials concentrate in the higher organisms, progressively accumulating.

Hard X-ray Microscope Opens New Vistas Alexander E. Braun, Senior Editor - 09/04/2008
The highest resolution microscope of its type, the hard X-ray Nanoprobe now operational at the Argonne National Laboratory is being used to study novel nanoscale materials and devices that might find application in more efficient photovoltaic cells and in next-generation computing.

Researchers Apply Self-Assembly to NIL Master for Bit-Patterned Media David Lammers, News Editor - 08/19/2008
Researchers working at Hitachi Global Storage Technologies and the University of Wisconsin have applied a self-assembly approach that would sharply reduce the time required to write NIL templates. The HDD industry is moving to bit-patterned media, and the self-assembly approach would sharply reduce the e-beam writing time for a 95 mm diameter template with terabit/in2 densities.

Yield, Surface Prep for Nano Devices Ahmed Busnaina, William Lincoln Smith Professor and Director, The NSF Nanoscale Science and Engineering Center for High-rate Nanomanufacturing and the NSF Center for Microcontamination Control, 06/01/2008 Nanoscale emerging research devices in the "beyond CMOS scaling" realm cover many applications and state variables. There have been many discussions of the characteristics, performance requirements, etc., of these devices, but the manufacture of these devices and the resulting yield has not been addressed....
