A team of researchers led by a physics graduate student at the University of Massachusetts Amherst made the surprising discovery of what they call a “shape-recovering liquid,” which defies some long-held expectations derived from the laws of thermodynamics.

The research, published in Nature Physics, details a mixture of oil, water and magnetized particles that, when shaken, always quickly separates into what looks like the classically curvaceous lines of a Grecian urn.

“Imagine your favorite Italian salad dressing,” says Thomas Russell, Silvio O. Conte Distinguished Professor of Polymer Science and Engineering at UMass Amherst and one of the paper’s senior authors.

The process of catalysis—in which a material speeds up a chemical reaction—is crucial to the production of many of the chemicals used in our everyday lives. But even though these catalytic processes are widespread, researchers often lack a clear understanding of exactly how they work.

A new analysis by researchers at MIT has shown that an important industrial synthesis process, the production of vinyl acetate, requires a catalyst to take two different forms, which cycle back and forth from one to the other as the chemical process unfolds.

Previously, it had been thought that only one of the two forms was needed. The new findings are published today in the journal Science, in a paper by MIT graduate students Deiaa Harraz and Kunal Lodaya, Bryan Tang, Ph.D., and MIT professor of chemistry and chemical engineering Yogesh Surendranath.

Treatment with chimeric antigen receptor (CAR)-T cell therapies is associated with important immune-related adverse events. In this Review, the authors discuss the standard-of-care management for cytokine release and immune effector cell-associated neurotoxicity syndromes, and the potential of other T cell druggable targets as well as cellular engineering strategies to develop safer CAR-T cells.

A team of researchers from University of Toronto Engineering has discovered hidden multi-dimensional side channels in existing quantum communication protocols.

The new side channels arise in quantum sources, which are the devices that generate the —typically photons—used to send secure messages. The finding could have important implications for quantum security.

“What makes quantum communication more secure than classical communication is that it makes use of a property of quantum mechanics known as conjugate states,” says Ph.D. student Amita Gnanapandithan, lead author on a paper published in Physical Review Letters.

Eye tracking plays a critical role in the latest virtual and augmented reality headsets and is an important technology in the entertainment industry, scientific research, medical and behavioral sciences, automotive driving assistance and industrial engineering. Tracking the movements of the human eye with high accuracy, however, is a daunting challenge.

Researchers at the University of Arizona Wyant College of Optical Sciences have now demonstrated an innovative approach that could revolutionize eye-tracking applications.

Their study, published in Nature Communications, finds that integrating a powerful 3D imaging technique known as deflectometry with advanced computation has the potential to significantly improve state-of-the-art eye tracking technology.

Unlike conventional silicon-based solar cells, perovskite solar cells (PSCs) are not only thin and lightweight, but can also be seamlessly applied to curved surfaces, like building facades and vehicle roofs. What’s more, they can be easily manufactured at room temperature using a solution process, leading to significantly reduced production costs.

However, for PSCs to achieve commercialization, it is crucial to develop technologies that maintain high efficiency over extended periods. A research team affiliated with UNIST has successfully made strides in this area. Their work is published in the journal Joule.

Professor Sang Il Seok of the School of Energy and Chemical Engineering at UNIST, along with researchers Jongbeom Kim and Jaewang Park, has developed an interlayer that leverages the specificity of organic cations on the surface of PSCs, simultaneously achieving and durability.

A research team has identified a previously unknown degradation mechanism that occurs during the use of lithium-ion batteries. Their findings are published in Advanced Energy Materials.

The team includes researcher Seungyun Jeon and Dr. Gukhyun Lim, led by Professor Jihyun Hong from the Department of Battery Engineering at POSTECH (Pohang University of Science and Technology), in collaboration with Professor Jongsoon Kim’s group at Sungkyunkwan University.

Lithium-ion batteries, which are essential for , typically use nickel-manganese-cobalt (NMC) ternary cathodes. To reduce costs, recent industry trends have favored increasing the nickel content while minimizing the use of expensive cobalt. However, higher nickel content tends to shorten the overall cycle life of the battery.
