Scientists have taken a major step toward a circular carbon economy by developing a long-lasting, economical catalyst that recycles greenhouse gases into ingredients that can be used in fuel, hydrogen gas, and other chemicals. The results could be revolutionary in the effort to reverse global warming, according to the researchers.
Read moreA new bendable supercapacitor made from graphene, which charges quickly and safely stores a record-high level of energy for use over a long period, has been developed and demonstrated by UCL and Chinese Academy of Sciences researchers.
Read moreFinding new semi-conductor materials that emit light is essential for developing a wide range of electronic devices. But making artificial structures that emit light tailored to our specific needs is an even more attractive proposition. However, light emission in a semi-conductor only occurs when certain conditions are met.
Read moreThe word “lens” takes its name from the Latin word for lentil. Both are both hemispheric shapes bound together on their flat surface. So a “flat lens” sounds like a contradiction of terms. Yet that is exactly what Andrei Faraon is working on at California Institute of Technology’s Nanoscale and Quantum Optics Lab.
Read moreIn 1900, German physician Paul Ehrlich came up with the notion of a “magic bullet.” The basic idea is to inject a patient with smart particles capable of finding, recognizing, and treating a disease. Medicine has pursued the magic bullet ever since.
Read morePeople rely on a highly tuned sense of touch to manipulate objects, but injuries to the skin and the simple act of wearing gloves can impair this ability.
Read moreA team led by Hongli (Julie) Zhu, an assistant professor of mechanical and industrial engineering at Northeastern, is using unique nanomaterials derived from cellulose to improve the large and expensive kind of batteries needed to store renewable energy harnessed from sources such as sunlight and the wind.
Read moreScientists from the Skoltech Center for Energy Science and Technology (CEST) and the Institute for Problems of Chemical Physics of Russian Academy of Sciences have developed a novel approach for preparing thin semiconductor fullerene films. The method enables fabrication of organic electronics without using toxic organic solvents and costly vacuum technologies, thus reducing the environmental risks and making organic electronics more accessible.
Read moreOne of the most promising alternative energy sources is hydrogen, which can be extracted from water and air. A catalyst is needed for a chemical process that releases hydrogen from an H2O molecule.
