Winter storms dumped records amounts of snow on the East Coast this February, leaving treacherous, icy sidewalks and roads in their wake. Now researchers from Canada are developing new methods to mass-produce a material that may help pedestrians get a better grip on slippery surfaces. The material, which is made up of glass fibers embedded in a compliant rubber, could one day be used in the soles of slip-resistant winter boots.
A new study will help researchers create longer-lasting, higher-capacity lithium rechargeable batteries, which are commonly used in consumer electronics. In a study published in ACS Nano, researchers showed how a coating that makes high-capacity silicon electrodes more durable could lead to a replacement for lower-capacity graphite electrodes.
The humble sewing machine could play a key role in creating "soft" robotics, wearable electronics and implantable medical systems made of elastic materials that are capable of extreme stretching. New stretchable technologies could lead to innovations including robots that have human-like sensory skin and synthetic muscles and flexible garments that people might wear to interact with computers or for therapeutic purposes.
Researchers at Northwestern University, working with a team of scientists from the United States and abroad, have recently developed a type of electronics that can bend and stretch to more than 200% their original size, four times greater than is possible with today’s technology. The key is a combination of a porous polymer and liquid metal.
A new study by civil engineers at Massachusetts Institute of Technology shows that using stiffer pavements on the nation's roads could reduce vehicle fuel consumption by as much as 3%—a savings that could add up to 273 million barrels of crude oil per year, or $15.6 billion at today's oil prices. This would result in an accompanying annual decrease in carbon dioxide emissions of 46.5 million metric tons.
A team of researchers at MIT has found a way to make complex composite materials whose attributes can be fine-tuned to give various desirable combinations of properties such as stiffness, strength, resistance to impacts, and energy dissipation.
As a raw material, petroleum is risky because its pricing is so volatile. By domesticating a Russian variety of dandelion and using the milky-white substance that seeps from its roots, researchers from Ford and Ohio State University believe they can create a new source of natural rubber for cupholders, floor mats, and interior trim in its cars.
