Scientists have developed a see-through glass display with a high white light contrast ratio that smoothly transitions between a broad spectrum of colors when electrically charged. The technology, from researchers at Jilin University in Changchun, China, overcomes limitations of existing electrochromic devices by harnessing interactions between metal ions and ligands, opening the door for numerous future applications. The work appears March 10 in the journal
Chem. We believe that the method behind this see-through, non-emissive display may accelerate the development of transparent, eye-friendly displays with improved readability for bright working conditions, says Yu-Mo Zhang, an associate professor of chemistry at Jilin University and an author on the study. As an inevitable display technology in the near future, non-emissive see-through displays will be ubiquitous and irreplaceable as a part of the Internet of Things, in which physical objects are in
Researchers have identified a critical mechanism that allows deadly bacteria to gain resistance to antibiotics.
The findings offer a potential new drug target in the search for effective new antibiotics as we face the growing threat of antimicrobial resistance (AMR) and infections caused by bacterial pathogens.
The study investigated quinolone antibiotics which are used to treat a range of bacterial infections, including TB (tuberculosis). Quinolones work by inhibiting bacterial enzymes, gyrase and topoisomerase IV, thereby preventing DNA replication and RNA synthesis essential to growth.
They are highly-successful antimicrobial agents widely used in current medicine, however bacterial resistance to them and other treatments is a serious problem.
Stockholm, Sweden, March 8, 2021 – A new study published by researchers at the PennEnvironment Research & Policy Center found microplastics in 100 percent of samples taken from 50 iconic rivers, lakes and streams in Pennsylvania. The researchers described their finding as troubling and said “it’s clear that the scope of plastic pollution in Pennsylvania extends far beyond what was previously thought”.
Dave Noble, spokesperson at Bluewater, a Swedish water company battling the need for single use plastic water bottles with innovative water tech and drinking bottle solutions, said the PennEnvironment study is the latest evidence of the pernicious plastics pollution plague sweeping the planet.
