Materials scientists have developed a simple, robust way to fabricate carbon-free and polymer-free, lightweight colloidal films for lithium-ion battery electrodes, which could greatly improve battery performance.
A research team at the Cornell Energy Materials Center has taken an important step forward with a chemical process that creates platinum-cobalt nanoparticles with a platinum enriched shell that show improved catalytic activity.
Guided by advanced molecular modeling on supercomputers, Massachusetts Institute of Technology scientists are investigating ways to turn atom-thick carbon layers into membranes for a new and improved desalination method in places with inadequate fresh water.
The National Physical Laboratory (NPL), along with partners In2Tec Ltd (UK) and Gwent Electronic Materials Ltd, have developed a printed circuit board (PCB) whose components can be easily separated by immersion in hot water.
The latest devolopments in the OLED lighting space will be one of the major topics at the forthcoming Printed Electronics USA 2012 conference. The event focuses on the commercialization of the technology, covering broadly organic, inorganic, thin film and flexible nanotechnologies.
Using a new method for precisely controlling the deposition of carbon, researchers have demonstrated a technique for connecting multi-walled carbon nanotubes to the metallic pads of integrated circuits without the high interface resistance produced by traditional fabrication techniques.
CIC microGUNE has initiated a line of collaboration with the Instituto Clarity Centre for Sensor Web Technologies de la Dublin City University (Ireland) to jointly promote research of new functional nanomaterials and their integration into microfluid systems which provide interesting properties for their application in multiple sectors.
An international team of researchers led by Empa, the Swiss Federal Laboratories for Materials Science and Technology, have now gained in-depth insights into the electronic structure of an iron oxide electrode - while it was in operation. This opens up new possibilities for an affordable hydrogen production from solar energy.
Researchers have introduced a new method for monitoring the growth of bacteria: The fluorescence of nanoparticles embedded in an agarose growth medium changes significantly when the pH value changes because of bacterial metabolism. This can be monitored in real time with a simple digital camera.
This innovation allows nanoparticles to be incorporated and evenly dispersed in a polymer mould in a very low proportion. The new process has produced a new material which increases mechanical as well as friction resistance, thereby maintaining the brackets' transparency.
Ingesting silver - in antimicrobial health tonics or for extensive medical treatments involving silver - can cause argyria, condition in which the skin turns grayish-blue. Brown researchers have discovered how that happens.
