Instead of having to use tons of crushing force and volcanic heat to forge diamonds, researchers at Case Western Reserve University have developed a way to cheaply make nanodiamonds on a lab bench at atmospheric pressure and near room temperature.
Nanomaterials are the heart of the smaller, better electronics developed during the last decade, as well as new materials, medical diagnostics and therapeutics, energy storage, and clean water. However, exposure to nanomaterials may have unintended consequences for human health and the environment.
The ability to shrink laboratory-scale processes to automated chip-sized systems would revolutionize biotechnology and medicine. For example, inexpensive and highly portable devices that process blood samples to detect biological agents such as anthrax are needed by the U.S. military and for homeland security efforts.
Sharp observation by doctoral student Mengmeng Cui in Thomas Russell’s polymer science and engineering laboratory at the University of Massachusetts Amherst recently led her to discover how to kinetically trap and control one liquid within another, locking and separating them in a stable system over long periods, with the ability to tailor and manipulate the shapes and flow characteristics of each.
By tuning gold nanoparticles to just the right size, researchers from Brown University have developed a catalyst that selectively converts carbon dioxide (CO2) to carbon monoxide (CO), an active carbon molecule that can be used to make alternative fuels and commodity chemicals.
Hydrogen is used as an energy source in fuel cells and can be produced from water by using sunlight and a suitable catalyst. In the journal Angewandte Chemie, American researchers have now introduced a new electrocatalyst consisting of a conductive network of core-shell nanowires that is just as efficient as conventional metal oxide films on indium tin oxide (ITO) and a great deal more transparent and robust.
University of Massachusetts Medical School Assistant Professor of Biochemistry and Molecular Pharmacology Gang Han, PhD, has received a $1.3 million EUREKA (Exceptional Unconventional Research Enabling Knowledge Acceleration) grant from the National Institute of Mental Health to develop light activated nanoparticles that can be used to image live brain tissue.

Canatu will be launching its new Generation 5 product family of CNB™ transparent conductive films for touch sensors, paving the way for high-contrast touch displays and revolutionary printed, flexible, foldable and 3D-shaped touch-enabled electronics products.
Some of the most dangerous cancers are those that can outmaneuver the very drugs designed to defeat them, but researchers are now reporting a new Trojan-horse approach. In a preliminary study in the journal ACS Nano focusing on a type of breast cancer that is highly resistant to current therapies, they describe a way to sneak small particles into tumor cells, lower their defenses and attack them with drugs, potentially making the therapy much more effective.
