  • An anode-free zinc battery that could someday store renewable energy
    on January 20, 2021 at 1:50 pm

    Renewable energy sources, such as wind and solar power, could help decrease the world’s reliance on fossil fuels. But first, power companies need a safe, cost-effective way to store the energy for later use. Massive lithium-ion batteries can do the job, but they suffer from safety issues and limited lithium availability. Now, researchers have made a prototype of an anode-free, zinc-based battery that uses low-cost, naturally abundant materials.

  • First glimpse of polarons forming in a promising next-gen energy material
    on January 4, 2021 at 6:19 pm

    Polarons affect a material’s behavior, and may even be the reason that solar cells made with lead hybrid perovskites achieve extraordinarily high efficiencies in the lab. Now scientists have used an X-ray free-electron laser to directly see and measure the formation of these ephemeral atomic lattice distortions for the first time.

  • A polarization-driven guide to making high-performance, versatile solar cells
    on January 4, 2021 at 4:04 pm

    When solar cells are exposed to sunlight, certain bound ‘charge pairs’ are generated in its components, which need to be separated for photocurrent generation. Ferroelectric materials, due to their spontaneous electric polarization, are highly efficient at charge separation but do poorly in light-to-electricity conversion. Now, scientists have demonstrated using theoretical calculations that antiperovskite oxides, a class of ferroelectric materials, show large absorption of sunlight, making them suitable photoabsorbers for thin film solar cells.

    on January 19, 2021 at 3:28 pm

    There are high hopes for the next generation of high energy-density lithium metal batteries, but before they can be used in our vehicles, there are crucial problems to solve. An international research team has now developed concrete guidelines for how the batteries should be charged and operated, maximizing efficiency while minimizing the risk of short circuits.

  • Inexpensive battery charges rapidly for electric vehicles, reduces range anxiety

    Range anxiety, the fear of running out of power before being able to recharge an electric vehicle, may be a thing of the past, according to a team of engineers who are looking at lithium iron phosphate batteries that have a range of 250 miles with the ability to charge in 10 minutes.

  • Lead poisoning of children
    on January 14, 2021 at 6:40 pm

    A remediation and public education effort at an abandoned battery recycling facility in Bangladesh eliminated most lead soil contamination, but levels of the toxic metal in children living near the site did not decrease nearly as much. The discrepancy reveals the scope of other lead exposure sources and the challenge they present to public health.

    on January 14, 2021 at 9:40 pm

    A team of biophysicists set out to tackle the long-standing question about the nature of force generation by myosin, the molecular motor responsible for muscle contraction. The key question they addressed – one of the most controversial topics in the field – was: how does myosin convert chemical energy, in the form of ATP, into mechanical work? The answer revealed new details into how myosin, the engine of muscle and related motor proteins, transduces energy.
