Advanced algorithm to study catalysts on material surfaces could lead to better batteries

A new algorithm opens the door for using artificial intelligence and machine learning to study the interactions that happen on the surface of materials.

Scientists and engineers study the that happen on the surface of materials to develop more energy efficient batteries, capacitors, and other devices. But accurately simulating these fundamental interactions requires immense computing power to fully capture the geometrical and chemical intricacies involved, and current methods are just scratching the surface.

“Currently it’s prohibitive and there’s no supercomputer in the world that can do an analysis like that,” says Siddharth Deshpande, an assistant professor in the University of Rochester’s Department of Chemical Engineering. “We need clever ways to manage that large data set, use intuition to understand the most important interactions on the surface, and apply data-driven methods to reduce the sample space.”

Three-mode smart window cut indoor temperature by 27°C and eliminate urban glare

In the building sector, which accounts for approximately 40% of global energy consumption, heat ingress through windows has been identified as a primary cause of wasted heating and cooling energy.

A KAIST research team has successfully developed a ‘pedestrian-friendly smart window’ technology capable of not only reducing heating and cooling energy in urban buildings but also resolving the persistent issue of ‘’ in urban living.

Professor Hong Chul Moon’s research team at KAIST’s Department of Chemical and Biomolecular Engineering have developed a ‘smart window technology’ that allows users to control the light and entering through windows according to their intent, and effectively neutralize glare from external sources.

Developer Proves His Game Engine Runs Faster Than Unity on Web

Gabriel Dechichi, a developer you might know from his challenge of making an Unreal Engine game in 4 weeks, is building his own C engine, and he’s ready to prove it’s better than Unity, at least in web space.

Dechichi made a demo where you can add hundreds of running mannequins and see how your system reacts to the stress. The creator claims his engine is “10x faster, 10x lighter, 10x better” than other software, and 14 times quicker than Unity in particular.

It’s obvious from first glance even at 100 characters that Dechichi’s engine runs smoother, but I tested it on my MacBook Pro, and while the C engine works with 1,000 units at 250 ms and 1 FPS, Unity took forever to load so many characters at 1,300 ms and 1 FPS. So, I guess, Dechichi is right, and we’ll see a nice addition to the gamedev world soon.

The Cosmic Owl: Astronomers discover a peculiar galaxy merger

An international team of astronomers reports the detection of a peculiar merger of two similar ring galaxies that morphologically resemble an owl’s face. The discovery of this galaxy merger, dubbed the “Cosmic Owl,” is presented in a research paper published June 11 on the arXiv preprint server.

Galaxy mergers play a crucial role in the evolution of galaxies. These events redistribute the gas around galaxies, impact the stellar kinematics, transform galaxy morphology, and eventually lead to effective stellar mass assembly.

Some lead to the formation of collisional ring galaxies (CRGs), which are relatively rare as only a few hundred of them have been detected in the local universe. Rings in such galaxies are created when one galaxy passes directly through the disk of another in a nearly head-on collision, causing gas and stars to be shocked outward into a circular or near-circular pattern.

Highly charged muonic ions observed in gas-phase experiment for first time

An international team of researchers, including members from the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU, WPI), has directly observed “highly charged muonic ions,” a completely new class of exotic atomic systems, in a gas-phase experiment for the first time. The study was published online on June 16 in Physical Review Letters.

The observation highlights the capabilities of advanced superconducting transition-edge-sensor (TES) microcalorimeters in revealing previously inaccessible atomic phenomena.

Normal atoms consist of a nucleus and bound electrons and are electrically neutral. However, when many electrons are removed, the atom becomes highly charged. These charged atoms, known as highly charged ions, are valuable tools for research across various fields, including fundamental physics, nuclear fusion, surface science, and astronomy.

‘The models were right’: Astronomers find ‘missing’ matter linking four galaxy clusters

Astronomers have discovered a huge filament of hot gas bridging four galaxy clusters. At 10 times as massive as our galaxy, the thread could contain some of the universe’s ‘missing’ matter, addressing a decades-long mystery.
