Penn research combines graphene and painkiller receptor into scalable chemical sensor
Researchers from the University of Pennsylvania have led an effort to create an artificial chemical sensor based on one of the human body's most important receptors, one that is critical in the action of painkillers and anesthetics. In these devices, the receptors' activation produces an electrical response rather than a biochemical one, allowing that response to be read out by a computer.

Nanostructures to facilitate the process to eliminate organic contaminants in water
Researcher at the Public University of Navarre has developed nanostructures that assist in the process to decontaminate water. The nanostructures are coated in titanium oxide to which nitrogen has been added. This allows sunlight, rather than ultraviolet radiation, to trigger the process involving the chemical reaction and destruction of contaminants.

Flexible supercapacitor raises bar for volumetric energy density
Scientists have taken a large step toward making a fiber-like energy storage device that can be woven into clothing and power wearable medical monitors, communications equipment or other small electronics. Their supercapacitor packs an interconnected network of graphene and carbon nanotubes so tightly that it stores energy comparable to some thin-film lithium batteries.

Physicists receive prestigious DOE honor for young faculty
Two Northwestern University physicists have been selected by the Department of Energy to receive significant research funding as part of the DOE's highly selective Early Career Research Program. Eric Dahl and Nathaniel Stern are among only 35 scientists at US universities and national laboratories to receive the honor this year. Each will receive $750,000 over five years. With this support, Dahl will build novel instruments for the detection of dark matter particles, and Stern will investigate quantum phenomena in two-dimensional materials.

Properties of water at nanoscale will help to design innovative technologies
Scientists from Politecnico di Torino (Turin, Italy) and Houston Methodist Research Institute (Houston, USA) have just proposed on Nature Communications a novel understanding of unexpected water properties at the nanoscale in the close proximity of solid surfaces. More rationally designed contrast agents for improved Magnetic Resonance Imaging performances are the first applications of the discovery.

New method sneaks drugs into cancer cells before triggering release
Biomedical engineering researchers have developed an anti-cancer drug delivery method that essentially smuggles the drug into a cancer cell before triggering its release. The method can be likened to keeping a cancer-killing bomb and its detonator separate until they are inside a cancer cell, where they then combine to destroy the cell.

Ultramicroscopy
This FIB doesn't lie: New NIST microscope sees what others can't
Microscopes don't exactly lie, but they have limitations. Scanning electron microscopes can't see electrical insulators, and their high energies can actually damage some types of samples. Researchers at NIST have built the first low-energy focused ion beam (FIB) microscope using lithium. The team's new approach opens up the possibility of creating a whole category of FIBs using any one of up to 20 different elements, greatly increasing the options for imaging, sculpting or characterizing materials.

Bioprinting a 3D liver-like device to detoxify the blood
Nanoengineers at the University of California, San Diego have developed a 3-D-printed device inspired by the liver to remove dangerous toxins from the blood. The device, which is designed to be used outside the body -- much like dialysis -- uses nanoparticles to trap pore-forming toxins that can damage cellular membranes and are a key factor in illnesses that result from animal bites and stings, and bacterial infections. Their findings were published May 8 in the journal Nature Communications.

Recycling the next generation
About 70 billion tons of raw materials are extracted world wide annually. That is twice as much as at the end of the 1970s. This trend is continuing -- even with finite resources. One way to have enough materials available for manufacturing new goods in future is to recycle continually. Fraunhofer researchers are working on the advanced 'Molecular Sorting' project for the next-generation circular economy.

Scientists create first living organism that transmits added letters in DNA 'alphabet'
Scientists at The Scripps Research Institute have engineered a bacterium whose genetic material includes an added pair of DNA 'letters,' or bases, not found in nature. The cells of this unique bacterium can replicate the unnatural DNA bases more or less normally, for as long as the molecular building blocks are supplied.

Discovery offers new possibilities for clean energy research
University of Houston physicists have discovered a new thermoelectric material offering high performance at temperatures ranging from room temperature up to 300 degrees Celsius, or about 573 degrees Fahrenheit. Zhifeng Ren, M.D. Anderson Chair professor of physics at UH and the lead author of a paper describing the discovery, published online by Nano Energy, said the work could be important for clean energy research and commercialization at temperatures of about 300 degrees Celsius.

Graphene for real-world devices
Graphene is an excellent conductor of electricity and heat, but a number of practical challenges must be overcome before it can emerge as a replacement for silicon. University of Texas professor Li Shi is exploring novel ways of supporting and connecting graphene using experimental and computational methods. Using the Stampede supercomputer, Shi inferred how phonons (the vibrations of atoms in solids) scatter as a function of the thickness of graphene layers.

Taking the lead out of a promising solar cell
Northwestern University researchers are the first to develop a solar cell with good efficiency that uses tin instead of lead perovskite as the harvester of light. The low-cost, environmentally friendly solar cell can be made easily using 'bench' chemistry -- no fancy equipment or hazardous materials. Perovskite solar cells are being touted as the 'next big thing in photovoltaics.' Lead perovskite has achieved 15 percent efficiency, and tin perovskite should be able to match -- and possibly surpass -- that.
