Researchers have found a way to control oxygen concentration in tantalum oxide films produced by atomic layer deposition. These thin films could be the basis for creating new forms of nonvolatile memory.
Two teams were recently awarded the Qualcomm Tricorder X Prize for developing handheld devices that can diagnose a range of diseases and check a patient's vital signs without invasive tests - inspired by Star Trek's medical 'tricorder' device.
Researchers have demonstrated a high performance flexible piezoelectric nanogenerator based on a piezoelectrically enhanced nanocomposite micropillar array of BaTiO3 nanoparticles embedded into a highly crystalline polymer for efficient energy harvesting and highly sensitive self-powered sensing.
Engineers have developed a breakthrough in electrolyte chemistry that enables lithium batteries to run at temperatures as low as -60 degrees Celsius with excellent performance - in comparison, today's lithium-ion batteries stop working at -20 degrees Celsius.
Researchers have discovered that a two-dimensional semiconductor with a broken inversion symmetry demonstrates rectification, or the property of a diode, under a magnetic field applied in a certain direction.
In what could be a major step forward for a new generation of solar cells called 'concentrator photovoltaics', researchers have developed a new semiconductor alloy that can capture the near-infrared light located on the leading edge of the visible light spectrum.
Scientists are gaining new insight into the smart materials used in ultrasound technology. While forming the most thorough model to date of how these materials work, they have found striking similarities with the behavior of water.
