Researchers have found a way to get electrons to travel much farther than was previously thought possible in materials for organic solar cells. This advance could make these solar cells much more useful than inorganic alternatives. “For years, people had treated the poor conductivity of organics as an unavoidable fact, and this shows that that’s not always the case,” says research leader Stephen Forrest, professor of engineering at University of Michigan.

Peter Mascher is a professor in the Department of Engineering Physics and holds the William Sinclair Chair in Optoelectronics at McMaster University in Ontario, Canada. There, he leads a research group specializing in the fabrication and characterization of nanostructures. Mascher was recently named technical editor of the ECS Journal of Solid State Science and Technology (JSS) in the area of dielectric science and materials. The Electrochemical Society: What made you want to take on an ECS editorial role? Peter Mascher: I’ve…

A new water-based air-conditioning system cools air to as low as 18 degrees Celsius (about 64 degrees Fahrenheit) without using energy-intensive compressors and environmentally harmful chemical refrigerants. This technology could potentially replace the century-old air-cooling principle that is still used in modern-day air-conditioners. Suitable for both indoor and outdoor use, the new system is portable and can be customized for all types of weather conditions. The team’s novel air-conditioning system is cost-effective to produce, and it is also more eco-friendly…

A new method to quickly produce fibers from carbon nanotubes is both handmade and high tech. The method allows researchers to make short lengths of strong, conductive fibers from small samples of bulk nanotubes in about an hour. In 2013, Rice University chemist Matteo Pasquali found a way to spin full spools of thread-like nanotube fibers for aerospace, automotive, medical, and smart-clothing applications. The fibers look like cotton thread but perform like metal wires and carbon fibers.

Nitrogen-doped carbon nanotubes or modified graphene nanoribbons could be effective, less costly replacements for expensive platinum in fuel cells, according to a new study. In fuel cells, platinum is used for fast oxygen reduction, the key reaction that transforms chemical energy into electricity. The findings come from computer simulations scientists created to see how carbon nanomaterials could be improved for fuel-cell cathodes. Their study reveals the atom-level mechanisms by which doped nanomaterials catalyze oxygen reduction reactions (ORR). Doping with nitrogen…

Sensors on tape that attach to plants yield new kinds of data about water use for researchers and farmers. “With a tool like this, we can begin to breed plants that are more efficient in using water,” says Patrick Schnable, plant scientist at Iowa State University. “That’s exciting. We couldn’t do this before. But, once we can measure something, we can begin to understand it.” The tool making these water measurements possible is a tiny graphene sensor that can be…

Over 1,840 articles were published in ECS journals in 2017, ranging from battery technology to materials science. Among those articles, “The Development and Future of Lithium Ion Batteries” by ECS member of 48 years, George E. Blomgren, stood out as the most downloaded paper of the year, with over 25,000 downloads in total. The open access paper was published in the Journal of The Electrochemical Society (JES) and has held the number one top download spot for the majority of…

A new chemical sensor prototype will be able to detect “single-fingerprint quantities” of chemicals and other substances at a distance of more than 100 feet—and its creators are working to make it the size of a shoebox. The device could potentially identify traces of drugs and explosives, as well as speed up the analysis of certain medical samples. A portable infrared chemical sensor could be mounted on a drone or carried by users such as doctors, police, border officials, and…

Applying a tiny coating of costly platinum just 1 nanometer thick—about 1/100,000th the width of a human hair—to a core of much cheaper cobalt could bring down the cost of fuel cells. This microscopic marriage could become a crucial catalyst in new fuel cells that use generate electricity from hydrogen fuel to power cars and other machines. The new fuel cell design would require far less platinum, a very rare metal that sold for almost $900 an ounce the day…
