Published New Si-based photocatalyst enables efficient solar-driven hydrogen production and biomass refinery


A research team has achieved a significant breakthrough in the development of a hybrid silicon photocatalyst.
Published Tall buildings could be built quicker if damping models were correct, study finds


Multi-story buildings are assembled over-cautiously to withstand wind strengths, researchers have found.
Published Combustion powers bug-sized robots to leap, lift and race


Researchers combined soft microactuators with high-energy-density chemical fuel to create an insect-scale quadrupedal robot that is powered by combustion and can outrace, outlift, outflex and outleap its electric-driven competitors.
Published Cheap and efficient catalyst could boost renewable energy storage


Storing renewable energy as hydrogen could soon become much easier thanks to a new catalyst based on single atoms of platinum.
Published Engineers grow full wafers of high-performing 2D semiconductor that integrates with state-of-the-art chips


Researchers have grown a high-performing 2D semiconductor to a full-size, industrial-scale wafer. In addition, the semiconductor material, indium selenide (InSe), can be deposited at temperatures low enough to integrate with a silicon chip.
Published How wind turbines react to turbulence


The output of wind turbines can rise or fall by 50 per cent in a matter of seconds. Such fluctuations in the megawatt range put a strain on both power grids and the turbines themselves. A new study presents a new stochastic method that could help to mitigate these sudden swings and achieve a more consistent electricity production.
Published Scientists develop method to detect deadly infectious diseases


Researchers have developed a way of detecting the early onset of deadly infectious diseases using a test so ultrasensitive that it could someday revolutionize medical approaches to epidemics. The test is an electronic sensor contained within a computer chip. It employs nanoballs -- microscopic spherical clumps made of tinier particles of genetic material -- and combines that technology with advanced electronics.
Published Predictive model could improve hydrogen station availability


Consumer confidence in driving hydrogen-fueled vehicles could be improved by having station operators adopt a predictive model that helps them anticipate maintenance needs, according to researchers.
Published Step change in upconversion the key to clean water, green energy and futuristic medicine


Achieving photochemical upconversion in a solid state is a step closer to reality, thanks to a new technique that could unlock vital innovations in renewable energy, water purification and advanced healthcare.
Published AI-driven tool makes it easy to personalize 3D-printable models


With Style2Fab, makers can rapidly customize models of 3D-printable objects, such as assistive devices, without hampering their functionality.
Published Making hydrogen from waste plastic could pay for itself


Researchers have found a way to harvest hydrogen from plastic waste using a low-emissions method that generates graphene as a by-product, which could help offset production costs.
Published Evolution wired human brains to act like supercomputers


Scientists have confirmed that human brains are naturally wired to perform advanced calculations, much like a high-powered computer, to make sense of the world through a process known as Bayesian inference.
Published Battery-free robots use origami to change shape in mid-air


Researchers have developed small robotic devices that can change how they move through the air by 'snapping' into a folded position during their descent. Each device has an onboard battery-free actuator, a solar power-harvesting circuit and controller to trigger these shape changes in mid-air.
Published AI foundation model for eye care to supercharge global efforts to prevent blindness


Researchers have developed an artificial intelligence (AI) system that has the potential to not only identify sight-threatening eye diseases but also predict general health, including heart attacks, stroke, and Parkinson's disease.
Published Not too big: Machine learning tames huge data sets


A machine-learning algorithm demonstrated the capability to process data that exceeds a computer's available memory by identifying a massive data set's key features and dividing them into manageable batches that don't choke computer hardware. The algorithm set a world record for factorizing huge data sets during a test run on the world's fifth-fastest supercomputer. Equally efficient on laptops and supercomputers, the highly scalable algorithm solves hardware bottlenecks that prevent processing information from data-rich applications in cancer research, satellite imagery, social media networks, national security science and earthquake research, to name just a few.
Published New ionic materials boost hydrogen fuel cell efficiency!


A research team has made a groundbreaking advancement in improving the efficiency of hydrogen fuel cells, which are gaining significant attention as eco-friendly next-generation energy sources.
Published Magnetic whirls pave the way for energy-efficient computing


Researchers have been able to increase the diffusion of magnetic whirls, so called skyrmions, by a factor of ten.
Published AI can help write a message to a friend -- but don't do it


Using artificial intelligence applications to help craft a message to a friend is not a good idea -- at least if your friend finds out about the use of AI, a new study suggests.
Published 'Brainless' robot can navigate complex obstacles


Researchers who created a soft robot that could navigate simple mazes without human or computer direction have now built on that work, creating a 'brainless' soft robot that can navigate more complex and dynamic environments.
Published What do neurons, fireflies and dancing the Nutbush have in common?


Synchronicity is all around us, but it is poorly understood. Computer scientists have now developed new tools to understand how human and natural networks fall in and out of sync.
