Physicists shatter stubborn mystery of how glass forms
Scientists have described how glasses form at the molecular level and provided a possible solution to a problem that has stumped scientists for decades. Their simple theory is expected to open up the study of glasses to non-experts and undergraduates as well as inspire breakthroughs in novel nanomaterials.
Nanogenerator harvests power from rolling tires
Engineers have developed a nanogenerator that harvests energy from a car's rolling tire friction.
Large-scale field-effect transistors based on solution-grown organic single crystals are fabricated
Scientists describe a simple solution processing method where well-aligned single-crystals of organic semiconductors throughout a 1cm × 2cm substrate can be grown from a droplet pinned by a metal needle. The well-controlled alignment of the crystals originates from the unidirectional receding of the pinned droplet regulated by the capillary force.
Making new materials with micro-explosions
Scientists have made exotic new materials by creating laser-induced micro-explosions in silicon, the common computer chip material.
X-Rays and electrons join forces to map catalytic reactions in real-time
New technique combines electron microscopy and synchrotron x-rays to track chemical reactions under real operating conditions.
Researchers introduce new layered semiconducting materials as silicon alternative
When the new iPhone came out, customers complained that it could be bent - but what if you could roll up your too big 6 Plus to actually fit in your pocket? That technology might be available sooner than you think.
Building a better semiconductor
In a new paper, scientists detail how they developed a method to change the electronic properties of materials in a way that will more easily allow an electrical current to pass through.
Swarms of tiny robots are joining forces to break through blocked arteries (w/video)
Swarms of microscopic, magnetic, robotic beads could be scrubbing in next to the world?s top vascular surgeons - all taking aim at blocked arteries.
University spinout signs deal to commercialize microchips that release therapeutics inside the body
An implantable, microchip-based device may soon replace the injections and pills now needed to treat chronic diseases: Earlier this month, MIT spinout Microchips Biotech partnered with a pharmaceutical giant to commercialize its wirelessly controlled, implantable, microchip-based devices that store and release drugs inside the body over many years.
Nanowaveguides open a new route to photonics
A new route to ultrahigh density, ultracompact integrated photonic circuitry has been discovered. Researchers have developed a technique for effectively controlling pulses of light in closely packed nanoscale waveguides, an essential requirement for high-performance optical communications and chip-scale quantum computing.
