University of Notre Dame researchers have developed a novel platform to more accurately detect and identify the presence and severity of peanut allergies, without directly exposing patients to the allergen.
In the journal Nature Nanotechnology, University of North Carolina Lineberger Comprehensive Cancer Center researchers report on strides made in the development of a strategy to improve the immune system's detection of cancer proteins by using “sticky” nanoparticles.
There hasn’t been a gold standard for how orthopaedic spine surgeons promote new bone growth in patients, but now Northwestern University scientists have designed a bioactive nanomaterial that is so good at stimulating bone regeneration it could become the method surgeons prefer.
Javier Vela, scientist at the U.S. Department of Energy’s Ames Laboratory, believes improvements in computer processors, TV displays and solar cells will come from scientific advancements in the synthesis of low-dimensional nanomaterials.
Scientists at the University of Vienna have created a new hybrid structure, termed buckyball sandwich, by encapsulating a single layer of fullerene molecules between two graphene sheets. Buckyball sandwiches combine for the first time soccerball-like fullerenes, each consisting of sixty carbon atoms, and graphene, a one-atom thick layer of carbon. This structure allows the scientist to study the dynamics of the trapped molecules down to atomic resolution using scanning transmission electron microscopy. They report observing diffusion of individual molecules confined in the two-dimensional space, find evidence for the rotation of isolated fullerenes within the structure, and even follow their merging into larger molecular clusters.
Queen’s University Belfast researchers have discovered a new way to create extremely thin electrically conducting sheets, which could revolutionise the tiny electronic devices that control everything from smart phones to banking and medical technology.
Scientists devised a new synthesis route to produce a catalyst that doubles the conversion rate compared to the best previously reported catalyst.
A new device design allows ten-fold increase in spin currents, laying the path to use in computing and high-efficiency electronics.
Imagine wearing a device that continuously analyzes your sweat or blood for different types of biomarkers, such as proteins that show you may have breast cancer or lung cancer. Rutgers engineers have invented biosensor technology – known as a lab on a chip – that could be used in hand-held or wearable devices to monitor your health and exposure to dangerous bacteria, viruses and pollutants.
Heterogeneous nanostructured materials are widely used in various optoelectronic devices, including solar cells. However, the nano-interfaces contain structural defects that can affect performance. Calculations run at NERSC helped researchers ID the root cause of the defects in two materials and provide design rules to avoid them.
A method that significantly cuts the time and cost needed to grow graphene has won a 2017 TechConnect National Innovation Award. This is the second year in a row that a team at Argonne’s Center for Nanoscale Materials has received this award.
A team led by the University of Washington and the Massachusetts Institute of Technology has for the first time discovered magnetism in the 2-D world of monolayers, or materials that are formed by a single atomic layer.
A research team led by Iowa State University's Zhe Fei has made the first images of half-light, half-matter quasiparticles. The discovery could be an early step to developing nanophotonic circuits that are up to 1 million times faster than current electrical circuits.
Columbia Engineers developed a technique inspired by the nacre of oyster shells, a composite material that has extraordinary mechanical properties, including great strength and resilience. By changing the crystallization speed of a polymer mixed with nanoparticles, the team controlled how nanoparticles self-assemble into structures at three different length scales. This multiscale ordering can make the base material almost an order of magnitude stiffer while retaining the desired deformability and lightweight behavior of the polymeric materials.
Scientists at Johns Hopkins have created a nanoparticle that carries two different antibodies capable of simultaneously switching off cancer cells' defensive properties while switching on a robust anticancer immune response in mice. Experiments with the tiny, double-duty "immunoswitch" found it able to dramatically slow the growth of mouse melanoma and colon cancer and even eradicate tumors in test animals, the researchers report.
Researchers at Argonne are collaborating with Honeywell UOP scientists to explore innovative energy and chemicals production.
New findings show that features more than 100x smaller than the optical wavelength can still be sensed by light. This could pave the way for major new applications in sensing, including measuring nanometric defects in computer chips and photonic devices.
A researcher with the Erik Jonsson School of Engineering and Computer Science at the University of Texas at Dallas has designed a novel computing system made solely from carbon that might one day replace the silicon transistors that power today’s electronic devices.
Precise fluorescent imaging at the molecular level has not been possible because of non-specific fluorescence by surrounding tissues. Now researchers have resolved many of these problems by using SWIR quantum dots in live mice to image working organs, take metabolic measurements, and track microvascular blood flow in normal brain and brain tumors
Researchers from Houston Methodist and Italian super sports car maker Automobili Lamborghini are working together on new carbon fiber materials for implantable devices used in therapeutic drug delivery and orthopedics.
