Photocatalysis using sunlight, an inexpensive catalyst and ordinary fescue grass harvested from a garden has produced hydrogen. The process developed by researchers at Wales' Cardiff University is unique in that it doesn't require the costly step of separating cellulose from the grass, making it a promising development for a more hydrogen-driven energy future.
Police seeking to unlock a dead crime victim's cellphone with fingerprint identification are getting some help from Anil Jain, a Michigan State University professor. He is using fingerprints of the victim that the police had on hand and coating them with a layer of metallic particles that will reproduce the conductivity of human skin and -- hopefully -- make them readable by the phone.
The technologies of 3D printing and 3D imaging may one day give patients with often-devastating nerve damage a customized cure. Researchers at the University of Minnesota are creating a soft, 3D-printed scaffold for nerve regeneration that incorporates droplets of nerve growth factor.
What could turn out to be the world's tallest timber skyscraper is being planned in the Netherlands. The 21-floor Haut project will feature cross-laminated timber and light, easy-to-assemble, prefabricated panels as well as energy-generating facades.
Leadership certainly requires conventionally measured intelligence. But emotional intelligence may be of greater value, giving leaders the ability to link the emotive and rational centers in their brains and connect and empathize effectively with others, says executive coach Rita Allen.
NASA is using space technology to help design shelters that better protect firefighters during wildfires. The project is based on NASA's flexible heat shield material, which works as a thermal blanket.
To cope with peak power demands in its large cargo airships, French startup Flying Whales turned to Skeleton Technologies, whose graphene-based ultracapacitors will supplement the existing 1.5 megawatts for cruise power with 2 more megawatts. That will give the massive aircrafts enough power to automatically adjust for wind gusts during energy-intensive activities such as winching heavy loads.
Technology for self-driving cars faces a paradox: The more reliable it is, the less safe its passengers may be in situations in which a human driver needs to intervene. When the human brain is tasked with monitoring reliable systems, it becomes bored and drifts to other stimuli, as experience with autopilot technology in aviation has shown.
Toyota's Mirai hydrogen-fueled car manages to blend zero emissions with unexpected power and handling. However, reviewer Bill Roth questions the viability of hydrogen fuel, exploring the four current options for generating enough of the gas so vehicles like the Mirai can take to the roads in volume.
Planned power plant shutdowns are a good time to go through a preventive maintenance checklist, such as ensuring that proper insulation is in place, writes Winston Saunders of Structsure Scaffold & Insulation.
