Published Computer vision researcher develops privacy software for surveillance videos



Computer vision can be a valuable tool for anyone tasked with analyzing hours of footage because it can speed up the process of identifying individuals. For example, law enforcement may use it to perform a search for individuals with a simple query, such as 'Locate anyone wearing a red scarf over the past 48 hours.'
Published Key to efficient and stable organic solar cells



A team of researchers has made a significant breakthrough in the field of organic photovoltaics.
Published Positive perceptions of solar projects



A new survey has found that for residents living within three miles of a large-scale solar development, positive attitudes outnumbered negative attitudes by almost a 3-to-1 margin. Researchers surveyed almost 1,000 residents living near solar projects.
Published Why can't robots outrun animals?



Robotics engineers have worked for decades and invested many millions of research dollars in attempts to create a robot that can walk or run as well as an animal. And yet, it remains the case that many animals are capable of feats that would be impossible for robots that exist today.
Published Computer game in school made students better at detecting fake news



A computer game helped upper secondary school students become better at distinguishing between reliable and misleading news.
Published A flexible and efficient DC power converter for sustainable-energy microgrids



A new DC-DC power converter is superior to previous designs and paves the way for more efficient, reliable and sustainable energy storage and conversion solutions. The development can efficiently interface with a wide range of energy sources while enhancing system stability and simplicity at an unprecedented efficiency.
Published Clearing the air: Wind farms more land efficient than previously thought



Wind power is a source of energy that is both affordable and renewable. However, decision-makers have been reluctant to invest in wind energy due to a perception that wind farms require a lot of land compared to electric power plants driven by fossil fuels. Research was based on the assessment of the land-use of close to 320 wind farms in the U.S. paints a very different picture.
Published How 3D printers can give robots a soft touch



Soft skin coverings and touch sensors have emerged as a promising feature for robots that are both safer and more intuitive for human interaction, but they are expensive and difficult to make. A recent study demonstrates that soft skin pads doubling as sensors made from thermoplastic urethane can be efficiently manufactured using 3D printers.
Published Trash to treasure -- researchers turn metal waste into catalyst for hydrogen



Scientists have found a way to transform metal waste into a highly efficient catalyst to make hydrogen from water, a discovery that could make hydrogen production more sustainable.
Published New computer vision tool wins prize for social impact



A team of computer scientists working on two different problems -- how to quickly detect damaged buildings in crisis zones and how to accurately estimate the size of bird flocks -- recently announced an AI framework that can do both. The framework, called DISCount, blends the speed and massive data-crunching power of artificial intelligence with the reliability of human analysis to quickly deliver reliable estimates that can quickly pinpoint and count specific features from very large collections of images.
Published Nanoscale movies shed light on one barrier to a clean energy future



New research is shedding light on one barrier to a clean energy future: corrosion. Using nanoscale imaging techniques, researchers have captured high-resolution videos of tiny crystals of ruthenium dioxide -- a key ingredient used to produce clean-burning hydrogen -- as they are eaten away by their acidic environment. The research could pave the way to more durable catalysts and dramatically extend the lifetime of devices needed to turn hydrogen green.
Published Star Trek's Holodeck recreated using ChatGPT and video game assets



Star Trek's Holodeck is no longer just science fiction. Using AI, engineers have created a tool that can generate 3D environments, prompted by everyday language.
Published A faster, better way to prevent an AI chatbot from giving toxic responses



A new technique can more effectively perform a safety check on an AI chatbot. Researchers enabled their model to prompt a chatbot to generate toxic responses, which are used to prevent the chatbot from giving hateful or harmful answers when deployed.
Published Discovering exceptional oxide ion conductivity at lower temperatures



Oxide ion conductors used in solid-state fuel cells often fail to reach full potential when operating at temperatures below 500 degrees Celsius, but researchers have recently found a solution to this problem. They demonstrated high conductivity and stability in bismuth-containing Sill n oxyhalides with triple fluorite-like layers.
Published Subterranean storage of hydrogen



Scientists are using computer simulations and laboratory experiments to see if depleted oil and natural gas reservoirs can be used for storing carbon-free hydrogen fuel. Hydrogen is an important clean fuel: It can be made by splitting water using solar or wind power, it can be used to generate electricity and power heavy industry, and it could be used to power fuel-cell-based vehicles. Additionally, hydrogen could be stored for months and used when energy needs outpace the supply delivered by renewable energy sources.
Published A smarter city skyline for flood safety



With climate change and rising urbanization, the likelihood and severity of urban flooding are increasing. But not all city blocks are created equal. Researchers investigated how urban layout and building structures contribute to pedestrian safety during flooding. Based on their simulated results, the team recommends modifying building corners and protective block layouts to reduce pedestrian risk.
Published Engineers design soft and flexible 'skeletons' for muscle-powered robots



Engineers designed modular, spring-like devices to maximize the work of live muscle fibers so they can be harnessed to power biohybrid robots.
Published New four-terminal tandem organic solar cell achieves 16.94% power conversion efficiency



Researchers have fabricated a new four-terminal organic solar cell with a tandem configuration with a 16.94% power conversion efficiency (PCE). The new device is composed by a highly transparent front cell that incorporates a transparent ultrathin silver (Ag) electrode of only 7nm, which ensures its efficient operation.
Published New privacy-preserving robotic cameras obscure images beyond human recognition



In a bid to restore privacy, researchers have created a new approach to designing cameras that process and scramble visual information before it is digitized so that it becomes obscured to the point of anonymity.
Published Machine learning enables viability of vertical-axis wind turbines



Researchers have used a genetic learning algorithm to identify optimal pitch profiles for the blades of vertical-axis wind turbines, which despite their high energy potential, have until now been vulnerable to strong gusts of wind.
