Exciton Surfing…

Topics: Alternate Energy, Applied Physics, Materials Science, Nanotechnology, Solar Power Organic solar cells (OSCs) are fascinating devices where layers of organic molecules or polymers carry out light absorption and subsequent transport of energy – the tasks that make a solar cell work. Until now, the efficiency of OSCs has been thought to be constrained byContinue reading “Exciton Surfing…”

Cold Atmospheric Plasmas…

Topics: Applied Physics, Chemistry, Physics, Plasma, Research ABSTRACT Cold atmospheric plasmas have great application potential due to their production of diverse types of reactive species, so understanding the production mechanism and then improving the production efficiency of the key reactive species are very important. However, plasma chemistry typically comprises a complex network of chemical speciesContinue reading “Cold Atmospheric Plasmas…”

Dielectric Laser Accelerators…

Topics: Applied Physics, Modern Physics, Particle Physics Physics Today 74, 8, 42 (2021); https://doi.org/10.1063/PT.3.4815 Particle accelerators are among the most important scientific tools of the modern age. Major accelerator facilities, such as the 27-km-circumference Large Hadron Collider in Switzerland, where the Higgs boson was recently discovered, allow scientists to uncover fundamental properties of matter and energy. ButContinue reading “Dielectric Laser Accelerators…”

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…”
