Researchers find exception to 200-year-old scientific law governing heat transfer

4 mars

A team of researchers led by the University of Massachusetts Amherst has recently found an exception to the 200-year-old law, known as Fourier’s Law, that governs how heat diffuses through solid materials.

Scientists reveal role of neighboring adsorbates and quantum tunneling in surface diffusion of hydrogen atoms

4 mars

A research group led by Prof. Yang Yong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has revealed the role of neighboring adsorbate and quantum tunneling in the diffusion of hydrogen on a graphene surface, which opens a possible way for ultrahigh precision (…)

Researchers develop electron beam accelerator to sterilize medical equipment

4 mars

During the manufacturing process, many medical devices or equipment for use on humans must be sterilized according to recognized standards. This includes gowns, surgical drapes, syringes and implantable medical devices. In fact, the United States has a huge medical device sterilization (…)

LHCb observes a new decay mode of the charmed beauty meson

4 mars

The LHCb collaboration recently reported on the arXiv preprint server the first observation of the decay of the Bc+ meson (composed of two heavy quarks, b and c) into a J/ψ charm-anticharm quark bound state and a pair of pions, π+π0. The decay process shows a contribution from an intermediate (…)

Multiparticle nanostructures for building better quantum technologies

4 mars

In Nature Physics, the LSU Quantum Photonics Group offers fresh insights into the fundamental traits of surface plasmons, challenging the existing understanding. Based on experimental and theoretical investigations conducted in Associate Professor Omar Magaña-Loaiza’s laboratory, these novel (…)

Tests show high-temperature superconducting magnets are ready for fusion

4 mars

In the predawn hours of Sept. 5, 2021, engineers achieved a major milestone in the labs of MIT’s Plasma Science and Fusion Center (PSFC), when a new type of magnet, made from high-temperature superconducting material, achieved a world-record magnetic field strength of 20 tesla for a (…)

A key to the future of robots could be hiding in liquid crystals

4 mars

Robots and cameras of the future could be made of liquid crystals, thanks to a new discovery that significantly expands the potential of the chemicals already common in computer displays and digital watches.

Gravity experiments on the kitchen table : Why a tiny, tiny measurement may be a big leap forward for physics

4 mars

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever.

Beyond the ink : Painting with physics

4 mars

Falling from the tip of a brush suspended in mid-air, an ink droplet touches a painted surface and blossoms into a masterpiece of ever-changing beauty. It weaves a tapestry of intricate, evolving patterns. Some of them resemble branching snowflakes, thunderbolts or neurons, whispering the (…)

Hyper-spectral-resolution stimulated Raman spectroscopy with amplified fs pulse bursts

4 mars

Stimulated Raman scattering, observed first in 1962, has become a versatile tool in diverse fields such as biological imaging, environmental gas sensing, materials characterization, and molecular dynamics tracking. The choice of laser sources for exciting molecules or materials is critical, as (…)
