  • Researchers challenge the Conservation Reserve Program status quo to mitigate fossil fuels
    on February 23, 2021 at 4:07 pm

    Amid population expansion and severe climate conditions threatening agricultural productivity, sustainable food production is a national priority. Simultaneously, advances in bioenergy agriculture are necessary to move our energy sector away from fossil fuels.

  • There is no one-size-fits-all road to sustainability on ‘Patchwork Earth’
    on February 22, 2021 at 1:26 pm

    In a world as diverse as our own, the journey towards a sustainable future will look different depending on where in the world we live, according to a recent article. There are many regional pathways to a more sustainable future, but our lack of understanding about how these complex and sometimes contradictory pathways interact (and in particular when they synergize or compete with one another) limits our ability to choose the ‘best’ one.

  • Shale gas development in PA increases exposure of some to air pollutants
    on February 18, 2021 at 7:01 pm

    Air pollution levels may have exceeded air quality standards during the development of some Marcellus Shale natural gas wells in Pennsylvania, potentially impacting more than 36,000 people in one year alone during the drilling boom, according to scientists.

  • Speeding up commercialization of electric vehicles
    on March 5, 2021 at 2:24 pm

    Researchers have developed a high-capacity cathode material that can be stably charged and discharged for hundreds of cycles without using the expensive cobalt (Co) metal. The day is fast approaching when electric vehicles can drive long distances with Li- ion batteries.

  • Environmental impact of computation and the future of green computing
    on March 2, 2021 at 11:54 pm

    Every aspect of modern computing, from the smallest chip to the largest data center comes with a carbon price tag. The tech industry and the field of computation as a whole have focused on building smaller, faster, more powerful devices — but few have considered their overall environmental impact. Researchers are trying to change that by challenging the field to add carbon footprint to the list of metrics when designing new processes, new computing systems, new hardware, and new ways to use devices.

  • A fluid solution to dendrite growth in lithium metal batteries
    on March 2, 2021 at 8:00 pm

    Lithium metal batteries have higher charge density than conventional lithium ion batteries but are prone to problems of tree-like metal dendrites, which can cause short circuits or explosions. A new article shows that flowing ions near the cathode can prevent this problem.

  • Weakness is strength for this low-temperature battery
    on February 25, 2021 at 4:33 pm

    Nanoengineers have discovered new fundamental insights for developing lithium metal batteries that perform well at ultra-low temperatures; mainly, that the weaker the electrolyte holds on to lithium ions, the better. By using such a weakly binding electrolyte, the researchers developed a lithium metal battery that can be repeatedly recharged at temperatures as low as -60 degrees Celsius.

  • New catalyst could enable better lithium-sulfur batteries, power next-gen electronics
    on February 22, 2021 at 2:50 pm

    Lithium-sulfur batteries, given their light weight and theoretical high capacities, are a promising alternative to conventional lithium-ion batteries for large-scale energy storage systems, drones, electric vehicles, etc. But at present, they suffer from poor battery life, limiting their applicability. Now, scientists have discovered a new catalyst material’s ability to significantly improve lithium-sulfur battery life, opening doors to their near-future practical commercial realization.

  • Dethroning electrocatalysts for hydrogen production with inexpensive alternative material
    on March 2, 2021 at 6:07 pm

    Scientists have discovered a new electrocatalyst for the oxygen evolution reaction (OER) in electrochemical water splitting: CaFe2O4. This inexpensive, non-toxic, and easy-to-synthesize material outperforms other bimetallic OER electrocatalysts and even surpasses the benchmark set by iridium oxide, paving the way to accessible hydrogen generation for upcoming hydrogen societies.

  • Biopolymer-coated nanocatalyst can help realize a hydrogen fuel-driven future
    on February 23, 2021 at 5:16 pm

    While popular as an eco-friendly fuel, hydrogen is difficult to produce efficiently in an eco-friendly manner (through sunlight-induced decomposition of water) due to stability issues of catalysts (chemical reaction facilitators). In a new study, scientists demonstrate water splitting under sunlight using polydopamine-coated zinc sulfide nanorods as a catalyst. In their paper, they report a remarkably enhanced hydrogen production rate and look into the causes, paving the way for a hydrogen-based future.

    on February 10, 2021 at 10:00 pm

    Scientists have uncovered dynamic, atomic-level details of how an important platinum-based catalyst works in the water gas shift reaction. The experiments provide definitive evidence that only certain platinum atoms play an important role in the chemical conversion, and could therefore guide the design of catalysts that use less of this precious metal.
