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…

Submit your manuscripts to the Journal of The Electrochemical Society (JES) Focus Issue on The Brain and Electrochemistry, Honoring R. Mark Wightman and Christian Amatore by March 11, 2018. This focus issue of the JES is devoted to work at the juncture of electrochemistry, the brain, and the nervous system. The issue will provide a forum for the discussion of research and developments on how the central (CNS) and the peripheral nervous systems (PNS) can be viewed and studied in…

Researchers have developed a prototype device that mimics natural photosynthesis to produce ethylene gas using only sunlight, water, and carbon dioxide. The novel method, which produces ethylene at room temperature and pressure using benign chemicals, could be scaled up to provide a more eco-friendly and sustainable alternative to the current method of ethylene production. Ethylene, which is the building block of polyethylene, is an important chemical feedstock produced in large quantities for manufacturing plastics, rubber, and fibers. More than 170…

The ECS Canada Section recently awarded Leah Ellis and Yurij Mozharivskyj the 2017 Canada Section Student Award and W. Lash Miller Award, respectively. Canada Section Student Award The Canada Section Student Award was established in 1987 to recognize promising young scientists and engineers in the field of electrochemical power sources. The 2017 award went to Leah Ellis, a PhD candidate at Dalhousie University working in lithium-ion battery research. “This ECS Canada Section Student Award is very prestigious,” Ellis said. “Looking…

By: Deepak Kumar, University of Illinois at Urbana-Champaign; Stephen P. Long, University of Illinois at Urbana-Champaign, and Vijay Singh, University of Illinois at Urbana-Champaign The aviation industry produces 2 percent of global human-induced carbon dioxide emissions. This share may seem relatively small – for perspective, electricity generation and home heating account for more than 40 percent – but aviation is one of the world’s fastest-growing greenhouse gas sources. Demand for air travel is projected to double in the next 20…

By: Joshua M. Pearce, Michigan Technological University Within the next month, energy watchers expect the Federal Energy Regulatory Commission to act on an order from Energy Secretary Rick Perry that would create new pricing rules for certain power plants that can store fuel on site to support grid resilience. This initiative seeks to protect coal-fired and nuclear power plants that are struggling to compete with cheaper energy sources. Perry’s proposed rule applies to plants that operate in regions with deregulated…

Pillared graphene would transfer heat better if the theoretical material had a few asymmetric junctions that caused wrinkles, report engineers. Materials scientist Rouzbeh Shahsavari of Rice University and alumnus Navid Sakhavand first built atom-level computer models of pillared graphene—sheets of graphene connected by covalently bonded carbon nanotubes—to discover their strength and electrical properties as well as their thermal conductivity. In a new study, they found that manipulating the joints between the nanotubes and graphene has a significant impact on the…
