Improving batteries By digging into the complex science behind the formation of dendrites that cause lithium-ion batteries to fail, research by Purdue University engineers could bring safer, longer-lasting batteries capable of being charged within minutes instead of hours. According to the researchers, dendrites form on anode electrodes and may continue to grow until causing an internal sho... » read more

Nanodiamonds are quantum’s best friend Purdue University researchers have demonstrated a new way to enhance the emission of single photons by using "hyperbolic metamaterials," in a step they say could be used in developing quantum computers and communications technologies. Optical metamaterials harness clouds of electrons called surface plasmons to manipulate and control light. The team p... » read more

3D nanoshaping A team of researchers led by Purdue University report they’ve developed a method for creating large-area patterns of 3D nanoshapes from metal sheets. They believe this represents a potential manufacturing system to inexpensively mass produce innovations such as "plasmonic metamaterials" for advanced technologies, and could enable high-speed electronics, advanced sensors and so... » read more

Biological circuits In recent years, researchers have made progress in the design and creation of biological circuits which can take a number of different inputs and deliver a particular kind of output — like electronic circuits. However, while individual components of such biological circuits can have precise and predictable responses, those outcomes become less predictable as more such ele... » read more

Safety first A technology designed for conventional lithium-ion batteries by Stanford University researchers warns the user before it overheats and bursts into flames. The goal was to create an early-warning system to saves lives and property, by detecting problems that occur during the normal operation of a battery, the researchers said. The technology does not apply to batteries damaged i... » read more

Airway muscle-on-a-chip mimics asthma A Harvard University research team has developed a human airway muscle-on-a-chip that could be used to test new drugs as it accurately mimics the way smooth muscle contracts in the human airway, under normal circumstances and when exposed to asthma triggers. The chip also gives a window into the cellular and even subcellular responses within the tissue ... » read more

Self-Assembling Nano Films Applying thin films with uniformity has always been an engineering challenge, but as feature sizes shrink the problem become even more pronounced. But a new approach developed by Lawrence Berkeley National Labs’ Materials Science Division could end up simplifying this process. The new approach used chloroform as an annealing solvent to create self-assembling arr... » read more
