Scientists have made a battery comprised of a polypeptide backbone decorated with viologen and nitroxide radicals. The approach avoids the ethical and environmental issues associated with obtaining lithium and cobalt, key constituents of lithium-ion batteries. Read the C&I Magazine article.
Applied chemistry highlights for June 2021.
All cereal crops – wheat, barley, rice and rye – are annual grasses. They need to be sown and harvested each year, which means regular tilling of the soil.
Last year saw the biggest boost to renewable energy capacity for 30 years, according to the IEA’s 2021 Market Update. And markets are set to continue to grow into 2022. Exceptionally high capacity additions will become the ‘new normal’ in 2021 and 2022, with renewables accounting for 90% of new power capacity expansion globally.
A new kind of vaccine may offer protection against a range of coronaviruses, animal studies show. A Duke University, US, research group developed the approach using a nanoparticle studded with 24 segments of the spike protein from SARS-CoV-2. It generated an outstanding antibody response against the pandemic virus in monkeys (Nature, doi: 10.1038/s41586-021-03594-0).
Scientists have developed a new material that improves the resolution of an ordinary light microscope so it can be used to examine fine details in living cells. Read more in C&I Magazine.
Covid-19 may be a blood-borne disease, infecting humans through the mouth – challenging the current view the virus is inhaled into the lungs as in respiratory diseases like the flu, a new paper hypothesises. This new model of SARS-CoV-2 infection could, if proven, affect how Covid-19 is prevented and treated. Read more in C&I Magazine.
US scientists have jammed microparticles with enzymes to detox bees that imbibe organophosphate pesticides.
A growing mountain of electronic waste is piling up. But recycling is not yet economically attractive, with few incentives for companies to design products with end of use in mind at the outset, reports Katrina Megget. Read the full feature article in C&I Magazine.
The International Energy Agency (IEA) has released what it describes as ‘the world’s first comprehensive study* of how to transition to a net zero energy system by 2050 while ensuring stable and affordable energy supplies, providing universal energy access, and enabling robust economic growth’.
