A new antimicrobial cotton textile with Cu ions in nanofibers
Cotton textiles are ubiquitous in daily life, and they are also one of the primary mediums for transmitting viruses and bacteria. Conventional approaches to fabricating antiviral and antibacterial textiles generally load the functional additives onto.....»»
Birnessite study offers insights for electrochemistry, energy storage
The adsorption of ions from the electrolyte at an electrode surface is a ubiquitous process, of use for both existing and emerging electrochemical energy technologies. But what happens when these ions penetrate very small spaces? To address this ques.....»»
Scientists discover how high-energy electrons strengthen magnetic fields
More than 99% of the visible universe exists in a superheated state known as plasma—an ionized gas of electrons and ions. The motion of these charged particles produces magnetic fields that form an interstellar magnetic web. These magnetic fields a.....»»
Is bacterial acidity a key to tackle antimicrobial resistance?
Decreasing bacterial acidity could help reduce antimicrobial resistance by eliminating bacteria that can survive being treated with antibiotics......»»
India fails to weed out illegal herbicide-tolerant cotton
A massive jump in the sale of herbicide-tolerant, genetically engineered cotton seeds in India's current cropping season has raised fears of unchecked use of glyphosate, a toxic weedicide linked to serious health issues including cancer......»»

Researchers have created insecticide-free, mosquito-resistant clothing using textile materials they confirmed to be bite-proof in experiments with live mosquitoes......»»
Mosquito-resistant clothing prevents bites in trials
North Carolina State University researchers have created insecticide-free, mosquito-resistant clothing using textile materials they confirmed to be bite-proof in experiments with live mosquitoes. They developed the materials using a computational mod.....»»
Device built for extreme environment could speed Actinium-225 production
High pressure ion chromatography—using a high-pressure pump to enable more rapid separation of ions—is one of the fastest and most efficient ways to do chemical separations......»»
Waste hop stem in the beer industry upcycled into cellulose nanofibers
Some three quarters of the biomass in hop plants used in beer-making ends up in landfills. But a group of Japanese researchers has developed a technique that 'upcycles' that waste hop into cellulose nanofibers (CNFs). A paper describing the technique.....»»
Bioinspired mineralization of calcium carbonate in peptide hydrogel
A team of researchers have developed a biomimetic mineralization of calcium carbonate using a multifunctional peptide template that can self-supply mineral sources, which in this case is a supply of carbonate ions, the precursor of calcium carbonate......»»
Inkjet printing show promise as new strategy for making e-textiles, study finds
In a new study, North Carolina State University researchers demonstrated they could print layers of electrically conductive ink on polyester fabric to make an e-textile that could be used in the design of future wearable devices......»»
Eco-friendly technology to produce energy from textile waste
A team of scientists from Kaunas University of Technology and Lithuanian Energy Institute proposed a method to convert lint-microfibers found in clothes dryers into energy. They not only constructed a pilot pyrolysis plant but also developed a mathem.....»»
Forget wearables: Future washable smart clothes powered by Wi-Fi will monitor your health
Purdue University engineers have developed a method to transform existing cloth items into battery-free wearables resistant to laundry. These smart clothes are powered wirelessly through a flexible, silk-based coil sewn on the textile......»»
Global travelers pick up numerous genes that promote microbial resistance
Carried like stowaways in the guts of international travelers, new and potentially deadly strains of antimicrobial resistant superbugs may be coming to a community near you, suggests new research from Washington University School of Medicine in St. L.....»»
Metal ions help COVID-19 virus to disguise itself
Scientists from The University of Texas Health Science Center at San Antonio have discovered a mechanism by which SARS-CoV-2 exploits changes in metal ion concentrations to disguise itself in the body. Varying concentrations of metal ions—positivel.....»»
Kudos, with its cotton-based, eco-friendly diaper, soaks up $2.4 million in seed funding
If you’ve experienced parenthood, you’re well versed in the surprisingly small world of disposable diapers. Help may be on the way. Kudos, a startup that is looking to reinvent the disposable diaper with sustainability in mind, announced.....»»
Shiny mega-crystals that build themselves
An international team led by Empa and ETH Zurich researchers is playing with shape-engineered nanoscale building blocks that are up to 100-times larger than atoms and ions. And although these nano "Lego bricks" interact with each other with forces va.....»»
Silver attacks bacteria, gets "consumed"
For millennia, silver has been utilized for its antimicrobial and antibacterial properties. Although its use as a disinfectant is widely known, the effects of silver's interaction with bacteria on the silver itself are not well understood......»»
