Most people think of water as existing in only one of three phases: Solid ice, liquid water, or gas vapor. But matter can exist in many different phases--ice, for example, has more than ten known phases, or ways that its atoms can be spatially arranged. The widespread use of piezoelectric materials, such as microphones and ultrasound, is possible thanks to a fundamental understanding of how an external force, like pressure, temperature, or electricity, can lead to phase transitions that imbue materials with new properties.
Using sound vibrations and pulses of near-infrared light, a Rutgers University scientist has developed a new "virtual biopsy" device that can quickly determine a skin lesion's depth and potential malignancy without using a scalpel.
HOUSTON -- (June 12, 2019) -- Using rare oxygen molecules trapped in air bubbles in old ice and snow, U.S. and French scientists have answered a long-standing question: How much have "bad" ozone levels increased since the start of the Industrial Revolution?
University of Colorado Boulder researchers have developed nano bio-hybrid organisms capable of using airborne carbon dioxide and nitrogen to produce a variety of plastics and fuels, a promising first step toward low-cost carbon sequestration and eco-friendly manufacturing for chemicals.
Researchers at Chalmers University of Technology, Sweden, have discovered a completely new way of capturing, amplifying and blinking light to the matter at the nanolevel. Using a tiny box, built from stacked atomically thin material, they have succeeded in creating a type of feedback loop in which light and matter become one. The discovery, which was recently published in Nature Nanotechnology, opens up new possibilities in the world of nanophotonics.
While dark matter abounds in the universe - it is by far the most common form of matter, making up about 85 percent of the universe's total - it also hides in plain sight. We don't yet know what it's made of, though we can witness its gravitational pull on known matter.
For more than a year, GozNym, a gang of five Russian cybercriminals, stole login credentials and emptied bank accounts from unaware Americans. To detect and quickly respond to escalating cyber-attacks like these, researchers at The University of Texas at San Antonio (UTSA) have developed the first framework to score the agility of cyber attackers and defenders. The cyber agility project was funded by the Army Research Office.
WEST LAFAYETTE, Ind. -- Electric cars rely on the same lithium-ion battery technology that's in smartphones, laptops and virtually everything electronic.
Biophysicists from the Moscow Institute of Physics and Technology have joined forces with colleagues from France and Germany to create a new fluorescent protein. Besides glowing when irradiated with ultraviolet and blue light, it is exceedingly small and stable under high temperatures.
AUSTIN, Texas -- The rose may be one of the most iconic symbols of the fragility of love in popular culture, but now the flower could hold more than just symbolic value. A new device for collecting and purifying water, developed at The University of Texas at Austin, was inspired by a rose and, while more engineered than enchanted, is a dramatic improvement on current methods. Each flower-like structure costs less than 2 cents and can produce more than half a gallon of water per hour per square meter.
With over 50,000 skills, Alexa is the clear industry leader in the smart assistants' industry. If you've ever wanted a smart robot to do the chores for you, Alexa is as close as you can get to that dream. Even better, she's getting smarter and more capable of accomplishing commands as technology gets improved.
After years of making progress on an organic aqueous flow battery, Harvard University researchers ran into a problem: the organic anthraquinone molecules that powered their ground-breaking battery were slowly decomposing over time, reducing the long-term usefulness of the battery.
Landing multi-rotor drones smoothly is difficult. Complex turbulence is created by the airflow from each rotor bouncing off the ground as the ground grows ever closer during a descent. This turbulence is not well understood nor is it easy to compensate for, particularly for autonomous drones. That is why takeoff and landing are often the two trickiest parts of a drone flight. Drones typically wobble and inch slowly toward a landing until power is finally cut, and they drop the remaining distance to the ground.
Researchers from Sweden's Chalmers University of Technology and the University of Gothenburg present a new method which can double the energy of a proton beam produced by laser-based particle accelerators. The breakthrough could lead to more compact, cheaper equipment that could be useful for many applications, including proton therapy.
A technique that introduces carbon-hydrogen molecules into a single atomic layer of the semiconducting material tungsten disulfide dramatically changes the electronic properties of the material, according to Penn State researchers at Penn State who say they can create new types of components for energy-efficient photoelectric devices and electronic circuits with this material.
