Scientists solve half-century-old magnesium dimer mystery
Magnesium dimer (Mg2) is a fragile molecule consisting of two weakly interacting atoms held together by the laws of quantum mechanics. It has recently emerged as a potential probe for...
Researchers boost microwave signal stability a hundredfold
Researchers have used state-of-the-art atomic clocks, advanced light detectors, and a measurement tool called a frequency comb to boost the stability of microwave signals 100-fold. This marks a giant step...
Next-generation solar cells pass strict international tests
A cost-effective method to stabilise perovskite solar cells could soon see them become commercially viable.
A stitch in time: How a quantum physicist invented new code from old tricks
Building large-scale quantum computers will require suppression of errors. Scientists have used a neat trick to apply powerful 3D error-suppression codes in a 2D architecture, something one industry insider said...
Geffen Playhouse has a hit Zoom magic show. How its star makes social distance vanish
Helder Guimarães' show "The Present" has sold out through mid-August. How he and a small team pull off the watch-from-home show and why it all works.
The self-synthesizing ribosome
As the cell's protein factory, the ribosome is the only natural machine that manufactures its own parts. That is why understanding how the machine, itself, is made, could unlock the...
Novel device harnesses shadows to generate electricity
Researchers have created a device called a 'shadow-effect energy generator' that makes use of the contrast in illumination between lit and shadowed areas to generate electricity. This novel concept opens...
Automated synthesis creates longest polysaccharide to date
Achievement paves the way to a better understanding of carbohydrate structures and functions
Solar energy farms could offer second life for electric vehicle batteries
As electric vehicles rapidly grow in popularity worldwide, there will soon be a wave of used batteries whose performance is no longer sufficient for vehicles that need reliable acceleration and...
A stitch in time: How a quantum physicist invented new code from old tricks
A scientist at the University of Sydney has achieved what one quantum industry insider has described as "something that many researchers thought was impossible".
Oriented hexagonal boron nitride foster new type of information carrier
Today's computers use the presence or absence of charge (0s and 1s) to encode information, where the physical motion of charges consume energy and cause heat. A novel alternative is...
Why toothpaste and cement harden over time
Take a look inside the cap of your favorite toothpaste, and you might see hard, white residue, a firm version of the smooth paste you squeeze onto your brush.
Chemical recycling makes useful product from waste bioplastic
A faster, more efficient way of recycling plant-based 'bioplastics' has been developed by a team of scientists.
Transport of mechanical energy -- even through damaged pathways -- demonstrated
Researchers have experimentally demonstrated a new way to transport energy even through wave-guides that are defective, and even if the disorder is a transient phenomenon in time.
Research team reports an important step to making optical simulators real-world devices
A group of Skoltech scientists, in collaboration with colleagues from the University of Southampton (UK), developed a fully optical approach to control the couplings between polariton condensates in optical lattices....
Researchers review advances in 3-D printing of high-entropy alloys
High-entropy alloys (HEAs) are at the frontier of the metal materials community. They are used as alternative materials in the production of high-temperature turbine blades, high-temperature molds and dies, hard...
When predictions of theoretical chemists become reality
Thomas Heine, professor of theoretical chemistry at TU Dresden, together with his team, first predicted a topological 2-D polymer in 2019. Only one year later, an international team led by...
Treadmills for an effective workout at home
Run toward these treadmills. (Chuttersnap via Unsplash/)Let’s be real, running outdoors is just not always feasible. Perhaps the weather is poor or your neighborhood isn’t jogger-friendly. Maybe you’ve got children at home that...
Understanding the 'fundamental nature' of atomic-scale defects
Materials scientists study metals, polymers, and other substances at the atomic level in order to find new ways to control a material's physical properties, such as how strong or how...
Scientists demonstrate new wavelength shift with diode-pumped continuous-wave Yb:CALGO laser
In 1960, Maiman's first demonstration of the ruby laser initiated the beginning of the laser era. Solid-state lasers still comprise one of the most rapidly developing branches of laser science...
Researchers demonstrate transport of mechanical energy, even through damaged pathways
Most technologies today rely on devices that transport energy in the form of light, radio, or mechanical waves. However, these wave-guiding channels are susceptible to disorder and damage, either in...
Visualization of functional components to characterize optimal composite electrodes
Researchers have developed a visualization method that will determine the distribution of components in battery electrodes using atomic force microscopy. The method provides insights into the optimal conditions of composite...
Laser cooling a nanomechanical oscillator close to its ground state
Researchers at the Swiss Federal Institute of Technology Lausanne (EPFL) and IBM Research Europe recently demonstrated the laser cooling of a nanomechanical oscillator down to its zero-point energy (i.e., the...
Visible-light-driven arylcarboxylation of styrenes with carbon dioxide and aryl halides
The use of carbon dioxide (CO2), which is an ideal one-carbon (C1) building block and is sustainable, abundant, low-cost and nontoxic, has attracted great attention in fine chemical synthesis. However,...
Discovery about the edge of fusion plasma could help realize fusion power
A major roadblock to producing safe, clean and abundant fusion energy on Earth is the lack of detailed understanding of how the hot, charged plasma gas that fuels fusion reactions...
