A touch of gold confers novel properties on semiconducting crystals

In a display of modern-day alchemy, researchers at the University of Warwick in the UK have shown that a touch of gold – or another noble metal – can change the structure of a crystal and thus alter its intrinsic properties. As the researchers report in a paper in Nature, they have found a way to …

Low voltage turns liquid metal droplets into streams

Researchers at North Carolina (NC) State University have developed a technique that allows them to produce streams of liquid metal at room temperature. By applying a low voltage to the liquid metal, the researchers were able to tune its surface tension across at least three orders of magnitude. “Liquids want to form droplets, because that …

The wireless device makes clean fuel from sunlight, carbon dioxide and water

Researchers have developed a standalone device that converts sunlight, carbon dioxide and water into carbon-neutral energy without requiring any additional components or electricity. The device, developed by a team from the University of Cambridge, is a significant step toward achieving artificial photosynthesis—a process mimicking plants’ ability to convert sunlight into energy. It is based on an advancedphotoshootet’ …

Recycling on the microscale has macro advantages

Growing populations and technological advances are driving consumption,using up raw materials,and creating a crisis in waste management.What can we do with the ever-growing volume of obsolete electronics or ‘e-waste’,for example,which will reach 50 million tons by 2021? A large proportion is currently transported to developing countries to be processed,while the rest is stockpiled or sent …

Investors Still Betting on Next Big Energy Storage Technology: Solid-State Batteries

The U.S.may have fallen behind Asia and Europe in battery manufacturing,but a number of well-funded companies are looking to get the country back in the game with a technology that could supersede today’s lithium-ion chemistries. Companies including Ionic Materials,QuantumScape,Sion power and Solid Power are developing all-solid-state batteries (ASSBs) that are expected to be safer and more energy-dense than the lithium-ion products …

Upcycling plastic waste toward sustainable energy storage

What if you could solve two of Earth’s biggest problems in one stroke? UC Riverside engineers have developed a way to recycle plastic waste,such as soda or water bottles,into a nanomaterial useful for energy storage. Mihri and Cengiz Ozkan and their students have been working for years on creating improved energy storage materials from sustainable sources,such as …

Exploring the interactions between sound,action and vision in robotics

In recent years,researchers have developed a growing amount of computational techniques to enable human-like capabilities in robots.Most techniques developed so far,however,merely focus on artificially reproducing the senses of vision and touch,disregarding other senses,such as auditory perception. A research team at Carnegie Mellon University (CMU) have recently carried out a study exploring the possibility of using …
