Video: Learn How Bubbles Form Inside a Lithium-air Battery
Understanding how these bubbles form during discharges could improve air batteries that have three times the energy capacity of lithium-ion batteries.
Indoor Temperature Variation Can Benefit Health
According to a recent study, exposure to environments outside a comfortable temperature could help tackle major metabolic diseases, such as diabetes and obesity, and should be reflected in modern building practices.
Common Pesticide Damages Honey Bees Ability to Fly
Biologists at the University of California San Diego have demonstrated for the first time that a widely used pesticide can significantly impair the ability of otherwise healthy honey bees to fly, raising concerns about how pesticides affect their capacity to pollinate and the long-term effects on the health of honey bee colonies.
New Sensor Increases Smartwatch Battery Life
Nearly 80 percent of the battery power in smartwatches is used up by the heart-rate monitor. But a new generation of sensors developed by EPFL startup ActLight consumes five times less energy.
Uber and Embraer to Explore VTOLs for Commuters
Uber Elevate Network could allow the development and deployment of small electric vertical take-off and landing vehicles for urban commutes.
Bonding Tapes: A Strong Option for Many Applications
Compared to fasteners, bonding tapes are faster and easier to apply, obsoletes the need for drilled holes which could cause leaks, and require much less labor time and cost to apply.
Bombardier to Provide Rail Cars for Chinese Railroad
The contract for five 8-car trainsets is valued at $79 million and follows a separate contract for 144 high speed cars announced in early March.
New Ultrasonic Clothes Dryer Design Cuts Energy, Time and Lint
Scientists at Oak Ridge National Laboratory, working in conjunction with the U.S. Department of Energy and General Electric, have built a prototype ultrasonic clothes dryer that does not use heat.
Changing Colors of Nanoparticles
Lawrence Livermore researchers have created a technique to change the color of assembled nanoparticles with an electrical stimulant.
Glass Fiber Coating Strengthens Composite Material
Glass fibers have many applications such as blades for wind turbines, glass fiber boats and more.
Dyneema® High-strength Lightweight Fabrics
Dyneema® high-strength lightweight fabrics are 40% less dense than aramid fabrics, 30% less dense than nylon or polyester and 15 times stronger than steel. The fabric is molecular engineered to offer game-changing properties to a range of industries.
A Once Forgotten Element Holds Promise for the Future of Electronics
Discovered more than 100 years ago, black phosphorus was soon forgotten when there was no apparent use for it. In what may prove to be one of the great comeback stories of electrical engineering, it now stands to play a crucial role in the future of electronic and optoelectronic devices.
Clean Water from a Plant-Based Membrane
A team of researchers has developed a plant-derived material that can be used to purify water, potentially being far more effective than current petroleum-based membrane materials.
Wonder Material? Novel Nanotube Structure Strengthens Thin Films for Flexible Electronics
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than the copper films currently used in electronics.
Low GWP Refrigerants - Understanding GWP, GHG, ODP and Climate Change
This is an engineer's perspective on global warming and climate from man-made gases and refrigerants. While the current administration may choose to deny the existence of climate change for their own agendas, most scientists agree that human impact has contributed to global warming and the world must control greenhouse gases (GHG).
Seeing the Future of Eyeglass Repair
LaserStar Technologies offers a range of manual laser welders for eyeglass repair.
3-D Printing Glass Objects
A team of researchers at Karlsruhe Institute of Technology in Germany has developed a way to 3-D print objects made of pure glass.
System Sorts Granular Bulk Materials Faster and More Accurately
Sand, gravel, coal, deicing salt or diamonds, grain, sugar, coffee or grapes and waste—a lot of everyday goods are more or less grainy. To classify this bulk material by quality and size, it must be sorted in a sophisticated process.
Ultraviolet Light Sensor for Wearables
Mass production technology for silicon based ultraviolet (UV) light sensors, suitable for smartphones and wearable devices in the Internet of Things (IoT) era, has been developed by a research team at Tohoku University and SII Semiconductor Corporation, a semiconductor manufacturer at Seiko Instruments Group.
The Financial Cost to Natural Resources of the BP Deepwater Horizon Spill
The total was determined by surveys of household willingness to pay to prevent damages from a similar event.
