Scientists discover how photon beam can flip the spin polarization of electrons emitted from topological insulator
(Phys.org) —Plain-looking but inherently strange crystalline materials called 3D topological insulators (TIs) are all the rage in materials science. Even at room temperature, a single chunk of TI is a good ...
An unlikely route to ferroelectricity
(Phys.org) -- Ferroelectricity, which was first observed in the 1940s, is an interesting phenomenon involving the spontaneous (non-induced) formation of charge polarization (separation of charge) in certain ...
Manganese dioxide nanorod technology could lead to a better capacitor
(Phys.org) —A new process for growing forests of manganese dioxide nanorods may lead to the next generation of high-performance capacitors.
Research shows viral DNA infects cells by changing from solid to fluid-like state
Many double-stranded DNA viruses infect cells by ejecting their genetic information into a host cell. But how does the usually rigid DNA packaged inside a virus' shell flow from the virus to the cell?
Scientists capture crystallization of materials in nanoseconds
(Phys.org) —Lawrence Livermore researchers for the first time have created movies of irreversible reactions that occur too rapidly to capture with conventional microscopy.
For newly discovered 'quantum spin liquid', the beauty is in its simplicity
(Phys.org)—A research team including scientists from the National Institute of Standards and Technology (NIST) has confirmed long-standing suspicions among physicists that electrons in a crystalline structure ...
Simulations reveal formation of some glassy materials like the setting of a bowl of gelatin
Gelatin sets by forming a solid matrix full of random, liquid-filled pores—much like a saturated sponge. It turns out that a similar process also happens in some metallic glasses, substances whose molecular ...
Simulation shows colloids can form into non-crystalline state at below freezing temperatures
Clemson leads research on new materials that could make it safer to store nuclear waste
Minerals that endure in nature for millions of years are inspiring a Clemson University-led research team to explore whether new materials could be developed to encase nuclear waste for safe storage.
New data-encoding scheme slashes energy needs for next-generation memory
Researchers from Rice University and UCLA unveiled a new data-encoding scheme this week that slashes more than 30 percent of the energy needed to write data onto new memory cards that use "phase-change memory" (PCM) -- a ...
Antenna-on-a-chip rips the light fantastic
(Phys.org)—A device that looks like a tiny washboard may clean the clocks of current commercial products used to manipulate infrared light.
New insight into an intriguing state of magnetism
(Phys.org)—Magnonics is an exciting extension of spintronics, promising novel ways of computing and storing magnetic data. What determines a material's magnetic state is how electron spins are arranged ...
Flexible silicon solar-cell fabrics may soon become possible
For the first time, a silicon-based optical fiber with solar-cell capabilities has been developed that has been shown to be scalable to many meters in length. The research opens the door to the possibility ...
Opportunity rover finds mineral vein deposited by water
(PhysOrg.com) -- NASA's Mars Exploration Rover Opportunity has found bright veins of a mineral, apparently gypsum, deposited by water. Analysis of the vein will help improve understanding of the history of ...
