Researchers from the Univ. of Illinois at Urbana-Champaign have demonstrated the first-ever recording of optically encoded audio onto a non-magnetic plasmonic nanostructure, opening the door to multiple uses in informational processing and archival storage.
A team of Columbia Engineering researchers has invented a technology, full-duplex radio integrated circuits (ICs), that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception at the same frequency in a wireless radio. Up to now, this has been thought to be impossible: transmitters and receivers either work at different times or at the same time but at different frequencies.
The pistons in your car engine rub up against their cylinder walls thousands of times a minute; without lubrication in the form of motor oil, they and other parts of the engine would quickly wear away, causing engine failure. Motor oil contains chemical additives that extend how long engines can run without failure, but, despite decades of ubiquity, how such additives actually work to prevent this damage have remained a mystery.
Materials resulting from chemical bonding of glucosamine, a type of sugar, with fullerenes, kind of nanoparticles known as buckyballs, might help to reduce cell damage and inflammation occurring after stroke. A team from the Max Planck Institute in Germany has tested this on mice, opening the door to potential new drugs for the cerebrovascular accident.
For the last seven years, Yale Univ. graduate student Staff Sheehan has been working on splitting water. Now, a paper published in Nature Communications reveals how one of the methods he and his team have uncovered for this process, using a specific iridium species as a water oxidation catalyst, could aid in the development of renewable fuels.
A study published by researchers at Argonne National Laboratory provides theoretical evidence for a new effect that may lead to a way of measuring the exact temperature at which superconductivity kicks in and shed light on the poorly understood properties of superconducting materials above this temperature.
Researchers at Massachusetts Institute of Technology have developed a method to stimulate brain tissue using external magnetic fields and injected magnetic nanoparticles: a technique allowing direct stimulation of neurons, which could be an effective treatment for a variety of neurological diseases, without the need for implants or external connections.
Tiny glass nanospheres coated on one side with a very fine gold film: Ludwig Maximillian Univ. of Munich scientists have shown that particles modified in this way can be moved about with high precision using laser beams, creating an optically controlled micro-elevator.
Borrowing a trick from nature, engineers from the Univ. of California at Berkeley have created an incredibly thin, chameleon-like material that can be made to change color by simply applying a minute amount of force. This new material-of-many-colors offers intriguing possibilities for an entirely new class of display technologies, color-shifting camouflage and sensors.
Computers that function like the human brain could soon become a reality thanks to new research using optical fibers made of specialty glass. The research, published in Advanced Optical Materials, has the potential to allow faster and smarter optical computers capable of learning and evolving.
Dental diseases, which are caused by the overgrowth of certain bacteria in the mouth, are among the most common health problems in the world. Now scientists have discovered that a material called graphene oxide is effective at eliminating these bacteria, some of which have developed antibiotic resistance. They report the findings in ACS Applied Materials & Interfaces.
A puzzling observation, pursued through hundreds of experiments, has led Stanford Univ. researchers to a simple yet profound discovery: Under certain circumstances, droplets of fluid will move like performers in a dance choreographed by molecular physics.
Univ. of California, Berkeley chemists have made a major leap forward in carbon-capture technology with a material that can efficiently remove carbon from the ambient air of a submarine as readily as from the polluted emissions of a coal-fired power plant. The material then releases the carbon dioxide at lower temperatures than current carbon-capture materials.
Lithium-ion batteries have enabled many of today’s electronics, from portable gadgets to electric cars. But much to the frustration of consumers, none of these batteries last long without a recharge. Now scientists report in ACS Nano the development of a new, “green” way to boost the performance of these batteries: with a material derived from silk.
Caltech scientists, inspired by a chemical process found in leaves, have developed an electrically conductive film that could help pave the way for devices capable of harnessing sunlight to split water into hydrogen fuel. When applied to semiconducting materials such as silicon, the nickel oxide film prevents rust buildup and facilitates an important chemical process in the solar-driven production of fuels such as methane or hydrogen.
To fully understand how nanomaterials behave, one must also understand the atomic-scale deformation mechanisms that determine their structure and, therefore, their strength and function. Researchers have engineered a new way to observe and study these mechanisms and, in doing so, have revealed an interesting phenomenon in a well-known material, tungsten.
The editors of R&D Magazine have announced an eligibility extension for products to be entered into the 2015 R&D 100 Awards. The 2015 R&D 100 Awards will honor products, technologies and services that have been introduced to the market between January 1, 2014 and March 31, 2015.
Most military battlefield casualties die before ever reaching a surgical hospital. Of those soldiers who might potentially survive, most die from uncontrolled bleeding. In some cases, there’s not much medics can do. That’s why Univ. of Washington researchers have developed a new injectable polymer that strengthens blood clots, called PolySTAT.
Researchers at the Univ. of California, Los Angeles and the Univ. Pierre et Marie Curie in Paris have identified a method for manufacturing longer-lasting and stronger forms of glass. The research could lead to more durable display screens, fiber-optic cables, windows and other materials, including cement.
An international team of researchers has used infinitely short light pulses to observe ultrafast changes in the electron-level properties of superconductors, setting a new standard for temporal resolution in the field. The scientists liken the new technique to the development of high-speed film capture in the early days of photography.
One third of the world’s food-producing land has been lost in the past 40 years as a result of soil degradation, putting global food security at risk. Researchers have discovered how aluminum, a toxic result of soil acidification, acts to reduce plant growth.
With more than five times the thermal conductivity of copper, diamond is the ultimate heat spreader. But the slow rate of heat flow into diamond from other materials limits its use in practice. In particular, the physical process controlling heat flow between metals and diamond has remained a mystery to scientists for many years.
Imagine setting a frying pan on the stove and cranking up the heat, only to discover that in a few spots the butter isn't melting because part of the pan remains at room temperature. What seems like an impossible scenario in the kitchen is exactly what happens in the strange world of quantum physics, researchers at the Univ. of Arizona have discovered.
Researchers have used an advanced model to simulate in unprecedented detail the workings of "resistance-switching cells" that might replace conventional memory for electronics applications, with the potential to bring faster and higher capacity computer memory while consuming less energy. These electromechanical "metallization cells" rapidly switch from high resistance to low resistance.
An extraordinary self-regulating heating effect that can be achieved in a particular type of magnetic material may open the doors to a new strategy for hyperthermia cancer treatment. Temperatures that can be tolerated by healthy body cells have long been known to destroy cancerous cells. An approach that uses magnetic particles introduced into tissue and heated remotely has found some success in treating cancer.
