Machine learning cracks the oxidation states of crystal structures

Chemical engineers have developed a machine-learning model that can predict a compound's oxidation state, a property that is so essential that many chemists argue it must be included in the periodic table.

New study presents transformative metasurface based on zerogap embedded template

Scientists have developed a new technique of predefining the crack pattern on a flexible substrate by a sequential deposition of metallic layers which leads to a formation of a zerogap between the adjacent lateral patterns.

Scientists discover support for disputed universal truth of particle physics

A measurement of a fundamental principle of the standard model of particle physics—lepton flavour universality—captured by the ATLAS detector at the Large Hadron Collider, is reported in a paper published in Nature Physics.

Scientists propose new source for rare subatomic particles

A paper based on joint research by Prof. Yuan Changzheng from Institute of High Energy Physics of the Chinese Academy of Sciences, and Prof. Marek Karliner from Tel Aviv University of Israel, was published in Physical Review Letters. It points out a new abundant source of antineutrons and hyperons. These rare subatomic particles are essential for studying forces governing the behavior of matter at the smallest distances, from atomic nuclei to neutron stars.

Here's How the Latest U.S. Intelligence Report on UFOs Might Bring Science to the UFO World

The new government report describes 144 sightings of unidentified aerial phenomena.

Understanding potential topological quantum bits

Scientists have been looking for half an electron as a basis for a quantum computer. They investigated a promising experimental setup just to find that the signals they measured were not telling the truth.

Using AI to predict 3D printing processes

Metal additive manufacturing (AM) experiments are slow and expensive. Engineers are using physics-informed neural networks to predict the outcomes of complex processes involved in AM. The team trained the model on supercomputers using experimental and simulated data. They recreated the dynamics of two benchmark experiments in metal AM. The method could lead to fast prediction tools for AM in the future.

The first commercially scalable integrated laser and microcomb on a single chip

Fifteen years ago, UC Santa Barbara electrical and materials professor John Bowers pioneered a method for integrating a laser onto a silicon wafer. The technology has since been widely deployed in combination with other silicon photonics devices to replace the copper-wire interconnects that formerly linked servers at data centers, dramatically increasing energy efficiency—an important endeavor at a time when data traffic is growing by roughly 25% per year.

Closing the gap on the missing lithium

There is a significant discrepancy between theoretical and observed amounts of lithium in our universe. Now, researchers have reduced this discrepancy by around 10 percent, thanks to a new experiment on the nuclear processes responsible for the creation of lithium.

A crystal made of electrons

Researchers at ETH Zurich have succeeded in observing a crystal that consists only of electrons. Such Wigner crystals were already predicted almost ninety years ago but could only now be observed directly in a semiconductor material.
