A study suggests that a computer-generated breathing coach could be as effective as sessions with a human trainer.

Muon spin rotation ( SR) spectroscopy is a powerful technique used to study the behavior of materials at the atomic level. In this study, researchers employed SR to examine phosphorus-containing 12-phosphatetraphene 1 molecule (muoniated radical). Their findings provide new insights into the radical's structure and behavior, advancing understanding of reactive species and radical behavior.

A nanotechnology-based drug delivery system developed to save patients from repeated surgeries has proved to have unexpectedly long-lasting benefits in lab tests -- a promising sign for its potential to help human patients.

Researchers developed a new optical system that uses holograms to encode information, creating a level of encryption that traditional methods cannot penetrate.

Researchers have shown that plumes of wildfire smoke can carry contaminants hundreds of kilometers, leaving a toxic and lingering footprint which has the potential to be re-released into the environment.

Researchers verified the chiral-induced spin selectivity effect, i.e., the influence of chiral molecules on spin, using spintronic analytical techniques.

Researchers report that a more efficient and environmentally friendly form of refrigeration might be on the horizon. The new technology is based on thermogalvanic cells that produce a cooling effect by way of a reversible electrochemical reaction. Thermogalvanic refrigeration is cheaper and more environmentally friendly than other cooling methods because it requires a far lower energy input, and its scalability means that it could be used for various applications -- from wearable cooling devices to industrial-grade scenarios.

Zaps of static electricity might be a wintertime annoyance, but to certain scientists, they represent an untapped source of energy. Using a device called a triboelectric nanogenerator (TENG), mechanical energy can be converted into electrical energy using triboelectric effect static. Many TENGs contain expensive, specially fabricated materials, but one team has instead used inexpensive store-bought tape, plastic and aluminum metal.

Researchers have developed a recyclable alternative to a durable class of plastics used for items like car tires, replacement hip joints and bowling balls.

How can the latest technology, such as solar cells, be improved? An international research team is helping to find answers to questions like this with a new technique. For the first time, the formation of tiny, difficult-to-detect particles -- known as dark excitons -- can be tracked precisely in time and space. These invisible carriers of energy will play a key role in future solar cells, LEDs and detectors.

Scientists have developed a new method for measuring temperature extremely accurately by using giant 'Rydberg' atoms. This atomic thermometer provides accurate measurements 'out of the box,' without needing initial factory adjustments, because it relies on the basic principles of quantum physics. By using Rydberg atoms' sensitivity to environmental changes, this technique could simplify temperature sensing in extreme environments, from space to high-precision industries.

AI agents trained in simulations that differ from the environments where they are deployed sometimes perform better than agents trained and deployed in the same environment, research shows.

Researchers have pioneered a new approach to simulate turbulent systems, based on probabilities.

A new technique to trap clusters of platinum atoms in nanoscale islands could lead to more efficient catalysts for the chemical industry.

Turning environmental waste into useful chemical resources could solve many of the inevitable challenges of our growing amounts of discarded plastics, paper and food waste, according to new research.

A new collaboration has unlocked new potential for the field by creating a novel high-performance organic electrochemical neuron that responds within the frequency range of human neurons.

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water.

This startling mechanism for promoting depolymerization relies on an additive that many plastics already contain: a pigment called carbon black that gives plastic its black color. Through a process called photothermal conversion, intense light is focused on plastic containing the pigment to jumpstart the degradation. The lab's method has since been tried out on such post-consumer waste as PVC pipes, black construction pipes, trash bags, credit cards, even those ubiquitous yellow rubber duckies. It works on all of them.

Scientists have made an advancement in the field of electrocatalysis. Their latest research sheds light on how catalysts can stay in unanticipated forms during the process of nitrate reduction. The study offers new insights that could pave the way for more efficient catalyst design.

Researchers have used electron spin resonance technology to observe the state and movement of the charge inside Ruddlesden-Popper tin -based perovskite solar cells, an emerging technology for next-generation solar cells. They have discovered a mechanism that improves the performance of these cells compared with conventional three-dimensional tin-based perovskite solar cells. Their findings signal a great leap forward in the development of high-efficiency, long-lasting solar cells.
