Researchers in AMBER, the Science Foundation Ireland-funded materials science research center hosted in Trinity College Dublin, have fabricated printed transistors consisting entirely of 2-D nanomaterials for the first time.
Experimental physicists at Saarland University have developed a thin nanomaterial with superconducting properties. Below about –200°C, these materials conduct electricity without loss, levitate magnets and can screen magnetic fields.
In a new discovery, alpha-tin, commonly called gray tin, exhibits a novel electronic phase when its crystal structure is strained, putting it in a rare new class of 3-D materials called topological Dirac semimetals. Only two other such materials are known to exist, discovered as recently as 2013.
Duke University researchers have created a new ‘spray-on’ digital memory using only an aerosol jet printer and nanoparticle ink. The device, which is analogous to a 4-bit flash drive, is the first fully-printed digital memory suitable for practical use in simple electronics such as environmental sensors or RFID tags.
Carbon nanotubes can be used to make very small electronic devices, but they are difficult to handle. University of Groningen scientists, together with colleagues from the University of Wuppertal and IBM Zurich, have developed a method to select semiconducting nanotubes from a solution and make them self-assemble on a circuit of gold electrodes.
Engineers at MIT have found a way to make graphene with fewer wrinkles, and to iron out the wrinkles that do appear. After fabricating and then flattening out the graphene, the researchers found each wafer exhibited uniform performance, meaning that electrons flowed freely across each wafer, at similar speeds, even across previously wrinkled regions.
Now it’s possible for anyone to see and share 3-D nanoscale imagery with a new open-source software platform developed by researchers at the University of Michigan, Cornell University, and open-source software company Kitware Inc.
While bigger nanowires can improve light confinement and performance, it increases both energy consumption and device footprint—both of which are considered ‘fatal’ when it comes to integration. Addressing this problem, researchers came up with an approach that involves combining a sub-wavelength nanowire with a photonic crystal platform.
Researchers have shown how to modify commercially available silicon wafers into a structure that efficiently absorbs solar energy and withstands the high temperatures needed for “concentrated solar power” plants that might run up to 24 hours a day.
Scientists at the Institute for Basic Science observe the real-time ultrafast bonding of lithium ions with the solvents, in the same process that happens during charging and discharging of lithium batteries, and conclude that a new theory is needed
A new Stanford study describes a model for designing novel materials used in electrical storage devices, such as car batteries and capacitors. This approach may dramatically accelerate discovery of new materials that provide cheap and efficient ways to store energy.
Seaweed could turn out to be an essential ingredient in the development of more sustainable ways to power our devices. Researchers have made a seaweed-derived material to help boost the performance of superconductors, lithium-ion batteries and fuel cells.
Researchers at The Australian National University have achieved a new record efficiency for low-cost semi-transparent perovskite solar cells in a breakthrough that could bring down the cost of generating solar electricity. The team has achieved 26% efficiency.
Plugging into renewable energy sources outweighs the cost and short driving ranges for consumers intending to buy electric vehicles, according to a new study. Queensland University of Technology researchers said environmental performance was more important than price or range confidence for electric vehicle consumers.
Natural gas producers want to draw all the methane they can from a well while sequestering as much carbon dioxide as possible, and could use filters that optimize either carbon capture or methane flow. No single filter will do both, but thanks to Rice University scientists, they now know how to fine-tune sorbents for their needs.
New research from the University of Manchester demonstrates the real-world potential of graphene oxide membranes for providing clean drinking water. The group found a strategy to avoid swelling of the membrane when exposed to water and can precisely control pore size in the membrane.
Researchers at the University of California, Riverside have found an innovative new use for a simple piece of glass tubing: weighing things. Their glass tube sensor will help speed up chemical toxicity tests, shed light on plant growth, and develop new biomaterials, among many other applications.
Taking a cue from the Marvel Universe, researchers report that they have developed a self-healing polymeric material with an eye toward electronics and soft robotics that can repair themselves. The material is stretchable and transparent, conducts ions to generate current and could one day help your broken smartphone go back together again.
A new anti-reflective coating and a novel chemical process for laser optics, developed by Lawrence Livermore National Laboratory researchers, represents an important breakthrough in its effort to boost the energy of the National Ignition Facility’s 192 giant lasers and cut the cost of repairing or replacing damaged optics vital to its operation.
To mimic bone’s structural variability, researchers fabricated steel with thin, alternating nanoscale layers of different crystal structures, some of which were just unstable enough to morph a bit under stress. That complicated microstructure prevented cracks from spreading in a straight line, slowing their take-over and preventing the material from collapsing.
Hokkaido University scientists have succeeded in developing a nickel complex that changes color and magnetism when exposed to methanol vapor. The new material can potentially be used not only as a chemical sensor, but also with future rewritable memory devices.
A group of researchers at Lund University in Sweden have made the first iron-based molecule capable of emitting light. This could contribute to the development of affordable and environmentally friendly materials for e.g. solar cells, light sources and displays.
Using a state-of-the-art microscopy technique, experimenters at the National Institute of Standards and Technology and their colleagues have witnessed a slow-motion, atomic-scale transformation of rust—iron oxide—back to pure iron metal, in all of its chemical steps.
A recent study, affiliated with UNIST has created a 3-D, tactile sensor that could detect wide pressure ranges from human body weight to a finger touch. This new sensor with transparent features is capable of generating an electrical signal based on the sensed touch actions, also, consumes far less electricity than conventional pressure sensors.
