It's not easy being green. Scientists for years have made small red and blue lasers, but other colors, including green, have been a challenge. A team has now filled this technology gap by creating orange, yellow and green lasers tiny enough to fit on a chip, opening up a wide range of applications in quantum

While some microbes can make people sick or spoil food, others are critical for survival. These tiny organisms can also be engineered to make specific molecules. Researchers have rewired one such microbe to help tackle greenhouse gases in the atmosphere: It takes in carbon dioxide (CO2) gas and produces mevalonate, a useful building block for

To understand the mysteries surrounding black holes, researchers at Tohoku University have created a simulation of accretion disk turbulence that possesses the highest-resolution currently available. Researchers at Tohoku University and Utsunomiya University have made a breakthrough in understanding the complex nature of turbulence in structures called "accretion disks" surrounding black holes, using state-of-the-art supercomputers to

Researchers have used vinegar vapor to dramatically improve UV sensors in a cheap, room-temperature process leading to better wearable devices. Researchers at Macquarie University have developed a new way to produce ultraviolet (UV) light sensors, which could lead to more efficient and flexible wearable devices. The study, published in the journal Small in July, shows

Synchronizing periodic excitations of photocatalysts with a Michelson interferometer on operando FT-IR spectroscopy, researchers succeeded in observing and identifying the reactive electron species for photocatalytic hydrogen evolution. In contrast to the traditional belief, this study demonstrates that not the free electrons in metal cocatalysts but the electrons trapped in the periphery of cocatalysts directly contribute

Researchers have successfully simulated higher-order topological (HOT) lattices with unprecedented accuracy using digital quantum computers. These complex lattice structures can help us understand advanced quantum materials with robust quantum states that are highly sought after in various technological applications. Researchers from the National University of Singapore (NUS) have successfully simulated higher-order topological (HOT) lattices with

Astronomers have spotted a pair of galaxies in the act of merging 12.8 billion years ago. The characteristics of these galaxies indicate that the merger will form a monster galaxy, one of the brightest types of objects in the Universe.

A team of scientists has unlocked the potential of 6G communications with a new polarization multiplexer. This allows multiple data streams to be transmitted simultaneously over the same frequency band, effectively doubling data capacity. A team of scientists has unlocked the potential of 6G communications with a new polarisation multiplexer. Terahertz communications represent the next

Chemists have developed a catalytic process that turns the largest component of today's plastic waste stream, polyolefin plastic bags and bottles, into gases -- propylene and isobutylene -- that are the building blocks of polypropylene and other types of plastics. The process uses inexpensive solid catalysts that can be scaled to industrial production, making this

Scientists have made a significant leap forward in the field of chiral molecules. The team achieved near-complete separation in quantum states for these essential components of life. This discovery challenges previous assumptions about the practical limits of quantum state control of chiral molecules and paves the way for new research directions in molecular physics and

Chemists have developed a method to furnish a range of molecules with a trifluoromethyl group attached to a sulfur, nitrogen or oxygen atom. Their procedure avoids the use of PFAS reagents. It thus provides an environmentally friendly synthesis route for pharmaceutical and agrochemical compounds that rely on the presence of the trifluoromethyl group. Chemists at

Researchers have developed a pioneering technique for producing large-scale graphene current collectors. This breakthrough promises to significantly enhance the safety and performance of lithium-ion batteries (LIBs), addressing a critical challenge in energy storage technology. Researchers at Swansea University, in collaboration with Wuhan University of Technology, Shenzhen University, have developed a pioneering technique for producing large-scale
