Carbon fiber-reinforced polymers (CFRPs) are used in the aerospace, automotive, and sports equipment industries. However, their recycling remains a major problem. In a recent study, researchers demonstrated a novel direct discharge electrical pulse method for the efficient, effective, and environmentally friendly separation of CFRPs to recover high-quality carbon fibers. This work is expected to pave

In recent years, more than 60 countries have developed strategies to stimulate the market ramp-up of hydrogen, particularly in the industrial sector. However, in 2023, less than ten percent of the originally announced green hydrogen production was realized, shows a new study. The main reason: hydrogen remains expensive and there is little willingness to pay

Water droplets under freezing conditions do not spontaneously detach from surfaces as they do at room temperature due to stronger droplet-surface interaction and lack of an energy transformation pathway. Since accumulated droplets or ice have to be removed manually or with mechanical equipment, which is costly and inefficient, preventing droplet accretion on surfaces is both

Cordierite, the material behind heat-resistant pizza stones, has been shown to resist changes in size despite significant temperature fluctuations. The reasons for this have been largely unexplained until now. New findings have profound implications for the design and development of advanced materials. Cordierite, a remarkable mineral familiar to many as the material behind heat-resistant pizza

Researchers have developed a drastically smaller and more energy efficient method of creating coveted photon pairs that influence each other from any distance. The technology could transform computing, telecommunications, and sensing. Physicists have spent more than a century measuring and making sense of the strange ways that photons, electrons, and other subatomic particles interact at

Although extremely flammable, cotton is one of the most commonly used textiles due to its comfort and breathable nature. However, in a single step, researchers can reduce the flammability of cotton using a polyelectrolyte complex coating. Although extremely flammable, cotton is one of the most commonly used textiles due to its comfort and breathable nature.

The night sky has always played a crucial role in navigation, from early ocean crossings to modern GPS. Besides stars, the United States Navy uses quasars as beacons. Quasars are distant galaxies with supermassive black holes, surrounded by brilliantly hot disks of swirling gas that can blast off jets of material. Following up on the

The name 'blue lurker' might sound like a villainous character from a superhero movie. But it is a rare class of star that NASA's Hubble Space Telescope explored by looking deeply into the open star cluster M67, roughly 2,800 light-years away. The name "blue lurker" might sound like a villainous character from a superhero movie.

Astronomers observed flashes of X-rays coming from a supermassive black hole at a steadily increasing clip. The source could be the core of a dead star that's teetering at the black hole's edge. One supermassive black hole has kept astronomers glued to their scopes for the last several years. First came a surprise disappearance, and

Scientists have come a step closer to understanding how collisionless shock waves -- found throughout the universe -- are able to accelerate particles to extreme speeds.

New research has identified the probable locations for critical metals needed to support a green economy. To transition to a green economy, we require more critical metals such as copper, rare earth elements and cobalt than are currently available. Therefore, we need to find new resources formed in different ways in areas that have not

A research team has achieved a groundbreaking quantum simulation of the non-Hermitian skin effect in two dimensions using ultracold fermions, marking a significant advance in quantum physics research.
