Heavy-duty trucks, such as the 18-wheelers that transport many of the world's goods from farm or factory to market, are virtually all powered by diesel engines. They account for a...

It's dark on the back road as a motorist speeds toward the intersection. Up ahead, the stop sign blends with the night and in seconds a deadly crash occurs. According to the U.S....

Batteries with metallic lithium anodes offer enhanced efficiency compared to conventional lithium-ion batteries because of their higher capacity. However, safety concerns and a short lifespan stand in the way. To...

Lithium batteries allow electric vehicles to travel several hundred miles on one charge. Their capacity for energy storage is well known — so is their tendency to occasionally...

Metal-air batteries are one of the lightest and most compact types of batteries but when not in use, they degrade quickly, as corrosion eats away at their metal electrodes. While...

Lithium-ion batteries commonly used in consumer electronics are notorious for bursting into flame when damaged or improperly packaged. Inspired by the unusual behavior of some liquids...

Researchers devised a method in which running a light emitting diode (LED) with electrodes reversed was able to cool another device nanometers away. They harnessed the chemical potential...

An Ohio State researcher shares with Tech Briefs the promise of potassium-oxygen batteries.

Three new unmanned helicopters were unveiled at AUVSI’s XPONENTIAL show in Chicago.

Fuel economy is a key factor in worldwide energy-consumption. One way to improve fuel economy is using driver feedback to promote efficient habits (eco-driving). Emerging research is looking into...

Smarter, better, faster, less expensive — those words are the mantra of today’s global economy. As organizations seek to streamline operations and do more with less, they...

Thin, durable heating patches were created using intense pulses of light to fuse tiny silver wires with polyester. Their heating performance is nearly 70 percent higher than similar patches. The inexpensive...

Recent technical advances have enabled flywheel energy storage systems (FESS) to become more compact and able to support higher-power applications. Due to their proven...

Wearable biosensors for health monitoring lack a lightweight, long-lasting power supply. A new method was developed for making a charge-storing system that is easily integrated into...

Growing demand for electric vehicles and more sustainable forms of transport means finding new forms of energy storage such as batteries, supercapacitors, and fuel cells. Currently, a major...

The first mass-produced electric vehicles (EVs) hit the road late in 2010 with the introduction of the Nissan Leaf, which remains the world’s top-selling,...

Millions of people who rely on pacemakers, defibrillators, and other livesaving implantable devices powered by batteries that need to be replaced every five to 10 years.

Titanium is as strong as steel but about twice as light. These properties depend on the way a metal’s atoms are stacked but random defects that arise in the...

nanotron, Munich, Germany, introduced 360° Edge Analytics tools and location-aware wireless sensors for manufacturing and healthcare. The products automatically extract event information in real...
