The Science Newswise — The ultrafast motion of electrons is the fundamental mechanism for chemical reactions. These reactions are at the core of many natural processes, including photosynthesis and radiation damage to DNA. Observing the motion of electrons at the atomic scale requires precisely synchronized flashes of X-ray radiation shorter than a femtosecond, or one quadrillionth of a second….
BYLINE: Jamie Oberdick Newswise — UNIVERSITY PARK, Pa. — Carbyne, a one-dimensional chain of carbon atoms, is incredibly strong for being so thin, making it an intriguing possibility for use in next-generation electronics, but its extreme instability causing it to bend and snap on itself made it nearly impossible to produce at all, let alone…
Newswise — A team of physicists has uncovered a surprising new way to explore one of science’s greatest challenges: uniting the two fundamental theories that explain how our universe works – Einstein’s theory of gravity and quantum mechanics. Despite decades of effort, no one has fully explained how gravity – which governs massive objects like…
BYLINE: Marcia Teckenbrock Newswise — A team of researchers from the U.S. Department of Energy’s Fermi National Accelerator Laboratory, Caltech, NASA’s Jet Propulsion Laboratory, University of Geneva and Federico Santa María Technical University in Chile recently tested a new technology to determine whether superconducting microwire single photon detectors, or SMSPDs, are feasible for use in…
Newswise — By splitting water molecules, fuel cells can turn electricity into hydrogen fuel. Running in the opposite direction, they consume hydrogen fuel to cleanly power multiple sectors. Typically, heat is a key ingredient for achieving high energy conversion efficiencies that can beat out combustion-based engines. But like a dripping pipe, fuel cells can leak…
BYLINE: Catie Himes, PNNL Newswise — RICHLAND, Wash.–Chemist Wendy Shaw has been named associate laboratory director of the Physical and Computational Sciences Directorate at the Department of Energy’s Pacific Northwest National Laboratory. In her previous role as PCSD’s chief science and technology officer, Shaw oversaw science and technology strategy and stewarded capability investments. She now helms…
Newswise — Superradiant Smith-Purcell radiation (S-SPR) is a kind of free electron radiation with a train of free electron bunches passing over a periodic grating. In theory, ultra-narrow spectral linewidth of S-SPR could be realized, which would be greatly beneficial to various applications such as imaging, sensing, communication, and et al. However, in the free…
Newswise — New Australian technology is set to transform the way that gastrointestinal cancers are detected and treated with precise, minimally invasive surgery. Backed by the Federal Government’s Economic Accelerator (AEA) Ignite Grant, researchers from the University of South Australia (UniSA) are using quantum technology to develop a first-of-its-kind laparoscopic probe that will allow surgeons…
BYLINE: Joseph McClain Newswise — NEWPORT NEWS, VA – Researchers have been working for decades to understand the architecture of the subatomic world. One of the knottier questions has been where the proton gets its intrinsic angular momentum, otherwise referred to as its spin. Nuclear physicists surmise that the proton’s spin most likely comes from…
Newswise — In this captivating interview, Dr. Shuo Sun, a leading researcher in quantum photonics, unravels the complexities of quantum entanglement and its potential applications. With a deep understanding of quantum mechanics, Dr. Sun provides a clear and accessible explanation of how entangled particles behave in ways that defy classical physics. He walks us through…
