How ultracold, superdense atoms become invisible
An atom's electrons are arranged in energy shells. Like concertgoers in an arena, each electron occupies a single chair and cannot drop to a lower tier if all its chairs are occupied. This fundamental property of atomic physics is known as the Pauli.....»»
CERN researchers measure speed of sound in the quark–gluon plasma more precisely than ever before
Neutron stars in the universe, ultracold atomic gases in the laboratory, and the quark–gluon plasma created in collisions of atomic nuclei at the Large Hadron Collider (LHC): they may seem totally unrelated but, surprisingly enough, they have somet.....»»
New synthesis method uses light reaction on a water surface
By forming chemical bonds between atoms, complex molecules such as those needed for medicines, crop protection products, or high-performance materials are prepared using synthetic chemistry. Such synthesis reactions typically require organic solvents.....»»
Innovative technique reveals that leaping atoms remember where they have been
University of Oxford researchers have used a new technique to measure the movement of charged particles (ions) on the fastest ever timescale, revealing new insights into fundamental transport processes. These include the first demonstration that the.....»»
A multi-ensemble atomic clock enhanced using quantum computing tools
Atomic clocks are a class of clocks that leverage resonance frequencies of atoms to keep time with high precision. While these clocks have become increasingly advanced and accurate over the years, existing versions might not best utilize the resource.....»»
Scientists find new way to roll atomically thin nanosheets into scrolls
Researchers from Tokyo Metropolitan University have come up with a new way of rolling atomically thin sheets of atoms into "nanoscrolls." Their unique approach uses transition metal dichalcogenide sheets with a different composition on either side, r.....»»
How semiconductor defects could boost quantum technology
In diamonds (and other semiconducting materials), defects are a quantum sensor's best friend. That's because defects, essentially a jostled arrangement of atoms, sometimes contain electrons with an angular momentum, or spin, that can store and proces.....»»
New adhesive tape picks up and sticks down 2D materials as easily as child"s play
Materials just atoms in thickness, known as two-dimensional (2D) materials, are set to revolutionize future technology, including in the electronics industry. However, commercialization of devices that contain 2D materials has faced challenges due to.....»»
Quantum simulation with ultracold fermions unveils pairing pseudogap
A research team has, for the first time, observed and quantitatively characterized the many-body pairing pseudogap in unitary Fermi gases. This achievement, pursued by the ultracold atomic community for nearly two decades, resolves longstanding debat.....»»
Advanced measurements unravel nanoscale phenomena in tungsten diselenide
Semiconductor 2D materials are a few atoms thick, and some of them exhibit localized emission, where light is emitted from such a small part of the layer that only one photon at a time is produced. This localized emission has unique properties and is.....»»
Engineers unmask nanoplastics in oceans, revealing their true shapes and chemistry
Millions of tons of plastic waste enter the oceans each year. The sun's ultraviolet light and ocean turbulence break down these plastics into invisible nanoparticles that threaten marine ecosystems......»»
Researchers develop new model to predict surface atom scattering
A group of Cornell-led researchers in the Center for Bright Beams has developed a new theoretical approach to calculate how atoms scatter from surfaces. The method, developed by recently conferred Cornell physics Ph.D. Michelle Kelley and her collabo.....»»
Team accomplishes precise measurements of the heaviest atoms
An international research team has successfully conducted ultra-precise X-ray spectroscopic measurements of helium-like uranium. The team, which includes researchers from Friedrich Schiller University Jena and the Helmholtz Institute Jena (both in Ge.....»»
Women and people of color remain "invisible" as most people pick white men as their heroes, researchers say
Women and people of color remain invisible to many people in Britain and the U.S. as people pick white men as their heroes instead, a study shows. Their achievements are often forgotten or not recognized when people are choosing who inspires them, re.....»»
New design improves water decontamination via plasma jet
Plasma is an ionized gas—that is, a gas containing electrons, ions, atoms, molecules, radicals, and photons. It is often called the fourth state of matter, and surprisingly, it permeates everything. Plasmas, which are artificially generated by tran.....»»
Innovative membrane platform enables analysis "down to a handful of gas atoms"
Northwestern University researchers have developed a novel method to host gas molecules as they are being analyzed in real time, using honeycomb structures found in nature as inspiration for an ultra-thin ceramic membrane they incorporated to encase.....»»
New material opens up possibility of converting water pollutants into hydrogen gas
WPI Researchers have developed a material to remove urea from water and potentially convert it into hydrogen gas. By building these materials of nickel and cobalt atoms with carefully tailored electronic structures, the group has unlocked the potenti.....»»
Unlocking the secrets of quasicrystal magnetism: Revealing a novel magnetic phase diagram
Quasicrystals are intermetallic materials that have garnered significant attention from researchers aiming to advance condensed matter physics understanding. Unlike normal crystals, in which atoms are arranged in an ordered repeating pattern, quasicr.....»»
"Magic trap" preserves quantum coherence in ultracold molecules longer than expected
Quantum technologies bring the promise of faster computing, enhanced drug development and new sensing applications. However, quantum behaviors are difficult to study experimentally since most systems can only sustain quantum effects for a short time......»»
Scientists develop high-power optic fiber laser to power nano satellites
The use of lasers in space is a reality. Even though radio waves have been the backbone of space communications for ages, the demand to convey more data, in a faster way, made these lighter, more flexible, and more secure infrared rays (invisible to.....»»
