Researchers Peer Into Nanowires to Measure Dopant Properties
Nanowires are synthesized from elements that form bulk semiconductors, whose electrical properties are in turn controlled by adding minute amounts of impurities called dopants. The amount of dopant determines the conductivity of the nanowire.

A persistent spin state that could revolutionize spintronics
By controlling the collective spin state of highly mobile electrons in semiconductors, researchers in the Materials Sciences Division (MSD) at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory have taken a major step forward in the technology of spintronics. At the same time they have discovered a new conservation law, an important advance in fundamental physics.

Silicon Micro-Islands and Nano-Spikes Channel Water on Glass Slides
University of Arkansas engineering researchers have created stable superhydrophilic surfaces on a glass substrate. The surfaces, made of randomly placed and densely distributed micron-sized silicon islands with nano-sized spikes, allow water to quickly penetrate textures and spread over the surface.

Magnetic nano-'shepherds' organize cells
Researchers created an environment where magnetic particles suspended within a specialized liquid solution acted like molecular sheep dogs by nudging free-floating human cells to form chains in response to external magnetic fields.

New method applies pesticides in nanofibers to keep chemicals on target
To prevent pesticides from drifting away and potentially posing risks to the environment, Cornell researchers have devised a solution: Apply the pesticides by encapsulating them in biodegradable nanofibers, which keeps then intact until needed and minimizes loss to drift or being washed away from the plants they are intended to protect.

A new family of molecules for self-assembly: The carboranes
To be useful in real-world applications, a self-assembled monolayer (SAM) of molecules on a surface must have a stable and controllable geometry. Researchers at Penn State and the Sigma-Aldrich company have found a way to control geometry and stability by making SAMs out of different carboranethiol isomers, which are cage-like molecules.
