In this work, researchers studied the outdoor and indoor photovoltaic performance of LHP-based devices utilizing Spiro-OMeTAD as the hole-transport material with commonly used dopants such as lithium bis(trifluoromethanesulfonyl)imide (Li-TFSI) or without any dopants.

A research team led by the School of Engineering of the Hong Kong University of Science and Technology (HKUST) has constructed an unprecedented chiral-structured interface in perovskite solar cells, which enhances the reliability and power conversion efficiency of this fast-advancing solar technology and accelerates its commercialization.

“Digitization cuts both ways.”

It has been one year since fires on the Hawaiian island of Maui killed 102 people, destroyed more than 2,200 buildings and displaced 5,000 people in the historic town of Lahaina. Today, signs of rebuilding are visible. The U.S. Army Corps of Engineers has leveled and graded the lots where homes once stood, and temporary FEMA housing is slated to open in October.

Scientists at Oxford University Physics Department have developed a revolutionary approach which could generate increasing amounts of solar electricity without the need for silicon-based solar panels. Instead, their innovation works by coating a new power-generating material onto the surfaces of everyday objects such as rucksacks, cars, and mobile phones.

A new construction biomaterial that uses living microorganisms to extract carbon dioxide from the atmosphere has been developed by a UCL graduate student and colleagues.

Someday, instead of large, expensive individual space satellites, teams of smaller satellites—known by scientists as a "swarm"—will work in collaboration, enabling greater accuracy, agility, and autonomy. Among the scientists working to make these teams a reality are researchers at Stanford University's Space Rendezvous Lab, who recently completed the first-ever in-orbit test of a prototype system able to navigate a swarm of satellites using only visual information shared through a wireless network.

The $184 billion market for artificial intelligence shows no signs of slowing. A big slice of that market is organizations, from businesses to government agencies, that rely on AI to help make decisions. A 2023 study by IBM found 43% of CEOs are using AI to make strategic decisions.

A research team led by Jackson Laboratory (JAX) Associate Professor Vivek Kumar, Ph.D., has developed a non-intrusive method to accurately and continuously measure mouse body mass using computer vision. The approach aims to reduce the stress associated with traditional weighing techniques, improving the quality and reproducibility of biomedical research involving mice.

My colleagues and I have developed an artificial intelligence system that helps buildings shift their energy use to times when the electric grid is cleaner.

The phrase "practice makes perfect" is usually reserved for humans, but it's also a great maxim for robots newly deployed in unfamiliar environments.

Noise pollution has become increasingly common in urban areas, stemming from traffic, construction activities, and factories, which can seriously impact health, causing stress, sleep disturbances, and cardiovascular issues. Consequently, various methods for noise reduction have been proposed, such as physically blocking the path of sound and active noise control. However, since sound travels through air, physically blocking sound can also lead to poor ventilation, highlighting the need for research into simultaneous sound attenuation and ventilation.

Solar panels work great in full sunlight conditions, but many regions have little sunlight on any given day, meaning there is less energy generated than needed. Now Tufts researchers have discovered that a particular type of jewel orchid, which thrives in low-light conditions, might offer a key to solving this problem.

Graphene plasmon polaritons are a class of hybrid quasi-particles with advantageous optoelectronic properties. These particles have proved promising for the development of miniaturized nanoscale circuits that operate in the terahertz and mid-infrared regions of the electromagnetic spectrum.

Perchlorate is found in a wide variety of foods, especially products popular with babies and kids, advocacy group says.

Researchers at the University of Toronto have designed a new AI model that understands how humans perceive creativity in chess.

A new cross-disciplinary study by Washington University in St. Louis researchers has uncovered an unexpected psychological phenomenon at the intersection of human behavior and artificial intelligence: When told they were training AI to play a bargaining game, participants actively adjusted their own behavior to appear more fair and just, an impulse with potentially important implications for real-world AI developers.

Green hydrogen is emerging as an important potential solution for decarbonizing transportation, but new energy efficiency findings indicate that it should be used strategically in heavy-duty road, rail, aviation and marine transportation, a University of Michigan study shows.

The survival of the reef is essentially in human hands.

As the U.S. faces significant challenges in scaling up production of hydrogen in cost-effective and environmentally friendly ways, a new Cornell study outlines strategies to meet up to 75% of the nation's future hydrogen demand by harnessing offshore wind energy.
