Stop-Motion Efficiency…

Topics: Applied Physics, Electrical Engineering, Nanotechnology, Semiconductor Technology A new ultrafast imaging technique that captures the motion of atoms in nanoscale electronic devices has revealed the existence of a short-lived electronic state that could make it possible to develop faster and more energy-efficient computers. The imaging technique, which involves switching the devices on and offContinue reading “Stop-Motion Efficiency…”

Scrofulous Signaling…

Topics: Applied Physics, Electrical Engineering, Materials Science, Optics ABSTRACT We present results of near-field radio-frequency (RF) imaging at micrometer resolution using an ensemble of nitrogen-vacancy (NV) centers in diamond. The spatial resolution of RF imaging is set by the resolution of an optical microscope, which is markedly higher than the existing RF imaging methods. HighContinue reading “Scrofulous Signaling…”

Nano Laser…

Topics: Applied Physics, Bose-Einstein Condensate, Lasers, Nanotechnology, Optics Physicists have taken a step towards realizing the smallest-ever solid-state laser by generating an exotic quantum state known as a Bose-Einstein condensate (BEC) in quasiparticles consisting of both matter and light. Although the effect has so far only been observed at ultracold temperatures in atomically thin crystalsContinue reading “Nano Laser…”

Drops in Cells…

Topics: Applied Physics, Biology, Microscopy, Molecules A major challenge in cell biology remains unraveling how cells control their biochemical reaction cycles. For instance, how do they regulate gene expression in response to stress? How does their metabolism change when resources are scarce? Control theory has proven useful in understanding how networks of chemical reactions canContinue reading “Drops in Cells…”

Adversary, Friendly, or Neutral…

Topics: Aerodynamics, Applied Physics, Biology, Exoplanets, General Relativity, SETI May 17, 2019- No, little green men aren’t likely after the conquest of humanity. Boyd’s piece for Phys.org highlights the reason why the Pentagon wants to identify UFOs: they’re unidentified. If a warfighter on the ground or in the sky can’t ID an object, that creates aContinue reading “Adversary, Friendly, or Neutral…”

The Power of ASM…

Topics: Alternate Energy, Applied Physics, Atomic-Scale Microscopy, Nanotechnology When Ondrej Krivanek first considered building a device to boost the resolution of electron microscopes, he asked about funding from the U.S. Department of Energy. “The response was not positive,” he says, laughing. He heard through the grapevine that the administrator who held the purse strings declaredContinue reading “The Power of ASM…”

Black Phosphorous…

Topics: Alternative Energy, Applied Physics, Battery, Nanotechnology, Research A new electrode material could make it possible to construct lithium-ion batteries with a high charging rate and storage capacity. If scaled up, the anode material developed by researchers at the University of Science and Technology of China (USTC) and colleagues in the US might be usedContinue reading “Black Phosphorous…”

B-TENG…

Topics: Applied Physics, Nanotechnology, Polymers, Research A new low-cost nanogenerator that can efficiently harvest electrical energy from ambient wind has been created by Ya Yang at the Beijing Institute of Nanoenergy and Nanosystems of the Chinese Academy of Sciences and colleagues. The team reports that the device achieves high electrical conversion efficiencies for breezes of 4–8 m/s (14–28 km/h) andContinue reading “B-TENG…”

Transparency…

Topics: Applied Physics, Nanotechnology, Optics At the focus of a laser, a 100-nm-wide gold nanoparticle can block more than half the light. If additional particles are added, the amount of blocked light increases exponentially, as modeled by the Beer–Lambert law. But theorists predict that in the right set of circumstances, the addition of a moleculeContinue reading “Transparency…”
