Bringing aromas indoors with the help of chemical products — yes, air fresheners, wax melts, floor cleaners, deodorants and others — rapidly fills the air with nanoscale particles that are small enough to get deep into your lungs, engineers have found over a series of studies.

Asteroids that orbit close to the Earth inevitably cause us some anxiety due to the even remote possibility of a collision. But their proximity also offers ample opportunities to learn more about the universe. Ryugu, a 900-meter diameter asteroid in the Apollo belt, has recently proven useful in our search for signs of life’s precursors

Researchers have found that adding just the right amount of disorder to the structure of certain materials can make them more than twice as resistant to cracking.

Researchers have explored a ‘quantum-inspired’ technique to make the ‘ones’ and ‘zeroes’ for classical computer memory applications out of crystal defects, each the size of an individual atom. This turns milimeter-sized crystals into computer memory devices capable of storing terabytes of data. This interdisciplinary revolution in computer memory took its inspiration from the radiation dosimeters

Three innovative design techniques substantially enhance wireless transmitter performance and can boost power efficiency and elevate data rates concurrently. This effectively aligns with the growing demand for speed and efficiency, accelerating the widespread deployment of wireless devices. This enables synergistic operation of wireless electronic devices and better quality of modern life.

As more satellites, telescopes, and other spacecraft are built to be repairable, it will take reliable trajectories for service spacecraft to reach them safely. Researchers are developing a methodology that will allow multiple CubeSats to act as servicing agents to assemble or repair a space telescope. Their method minimizes fuel consumption, guarantees that servicing agents

A groundbreaking study explores Ba-Si orthosilicate oxynitride-hydride (Ba3SiO5 xNyHz) as a sustainable catalyst for ammonia synthesis, offering a potential alternative to traditional transition metal-based systems. Synthesized through low-temperature solid-state reactions and enhanced with ruthenium nanoparticles, these compounds demonstrated improved catalytic performance under milder conditions, providing a more energy-efficient route to ammonia production. This approach also

The process of separating useful molecules from mixtures of other substances accounts for 15% of the nation’s energy, emits 100 million tons of carbon dioxide and costs $4 billion annually. In a new study, researchers have found these manufactured separation materials don’t function as intended because the pores are so packed with polymer they become

The Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and NTT Research, Inc., a division of NTT, announced the publication of research showing an application of machine-learning directed optimization (ML-DO) that efficiently searches for high-performance design configurations in the context of biohybrid robots. Applying a machine learning approach, the researchers created mini

Is it possible to tile a surface with a single shape in such a way that the pattern never repeats itself? In 2022, a mathematical solution to this ‘Einstein problem’ was discovered for the first time. Researchers have now also found a chemical solution: a molecule that arranges itself into complex, non-repeating patterns on a
