A little zinc can do a lot of damage to graphene. Rice University researchers have taken advantage of that to create single-atomic-layer lithography. The Rice lab of chemist James Tour sputtered zinc onto multilayered graphene, enabling the team to remove a single layer at a time without disturbing the layers beneath.
Researchers in the University of Arizona's physics department, along with collaborators from MIT and the National Materials Science Institute in Japan, found that a graphene layer on boron nitride, instead of the commonly used silicon oxide found in microchips, could significantly improve its electronic properties.
Computer scientists at the National Institute of Standards and Technology (NIST) have improved software that can take much of the guesswork out of difficult materials development and environmental simulation problems.

Epoxy materials are being transformed into stiffer, lighter, and stronger materials thanks to fullerenes and carbon nanotubes (CNTs). Dongsheng Mao, Applied Nanotech, describes a process involving multi-walled carbon nanotubes that have stronger mechanical properties yet remain lightweight and within end-product cost parameters.
New research from the University of Pennsylvania demonstrates a more consistent and cost-effective method for making graphene. Using normal pressures and electropolished copper foil, the researchers achieved single-layer graphene sheets over 95% of the available surface area.
Global production value of nanocarbon products -- single-walled carbon nanotubes (SWNT), multi-walled carbon nanotubes (MWNT), fullerenes, graphene, carbon nanofiber, and nanodiamonds -- will triple over the next four years in value, and by orders-of-magnitude in actual production, according to a recent analyst report.
Rice University has developed an efficient method to disperse nanotubes in a way that preserves their unique properties and adds more. The technique allows inorganic metal complexes with different functionalities to remain in close contact with single-walled carbon nanotubes while keeping them separated in a solution.
Iranian researchers at Kashan University calculated the physical and mechanical properties of multi-walled carbon nanotubes (MWCNT) and nitride-Bohr nanotubes in a move to help improve the design of arms for nano-robots.
With electron beam lithography and etching, quantum dot size and position can be controlled and replicated. Tests at the NIST confirm that these etched quantum dots emit single particles of light, boosting prospects for powering new types of devices for quantum communications.
A prototype implantable eye pressure monitor for glaucoma patients is believed to contain the first complete millimeter-scale computing system. And a compact radio that needs no tuning to find the right frequency could be a key enabler to organizing millimeter-scale systems into wireless sensor networks.
A pentaphenylene molecule sandwiched between two electrodes exhibited significantly different conductance depending on its tilt angle in relation to the electrodes. This research, carried out at Arizona State University's Biodesign Institute and confirmed with a jiggle test, could influence nanoscale designs of telecommunications, memory, sensors, and other electronics.
