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.....»»
Agronomists find green way to mitigate the effects of soil salinity
Most crops are sensitive to soil salinity. Excess salts cause salt stress—plants lack water, photosynthesis is suppressed, respiration worsens, chlorophyll breaks down, and potassium ions leak. Water-soluble toxic salts stimulate the synthesis of r.....»»
Do or dye: Synthetic colors in wastewater pose a threat to food chains worldwide
Dyes widely used in the textile, food and pharmaceutical industries pose a pressing threat to plant, animal and human health, as well as natural environments around the world, a new study has found......»»
Examining the synergistic roles of platinum nanoparticles and sodium ions within beta zeolites
Organic N-alkyl amines are important chemical products and intermediate with wide applications in the fields of daily chemicals, pesticides, pharmaceuticals, surfactants, and life sciences. The C–N bonds formed by alkylating reagents (halocarbons,.....»»

Electrons are quick-change artists in molten salts, chemists show
In a finding that helps elucidate how molten salts in advanced nuclear reactors might behave, scientists have shown how electrons interacting with the ions of the molten salt can form three states with different properties. Understanding these states.....»»
Scientists release 10-meter-resolution cotton map of Xinjiang, China
Scientists from the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences (CAS), together with collaborators from Shihezi University (Xinjiang, China) and University of Toronto (Toronto, Canada), have proposed a cotton map.....»»
Study demonstrates antimicrobial action of polyalthic acid from copaiba oil
Polyalthic acid from copaiba oil is an effective antibacterial and should be used to develop alternative medications that can contribute to the effort to overcome antimicrobial resistance ("superbugs"), according to an article by researchers based in.....»»
Harnessing molecular power: Electricity generation on the nanoscale
Wave energy technology is a proven source of power generation, but there is power inherent in every molecule of liquid on Earth, even when the liquid is at rest. At the molecular scale, atoms and ions are always moving. If this nanoscale movement can.....»»
Targeting a coronavirus ion channel could yield new COVID-19 drugs
The genome of the SARS-CoV-2 virus encodes 29 proteins, one of which is an ion channel called E. This channel, which transports protons and calcium ions, induces infected cells to launch an inflammatory response that damages tissues and contributes t.....»»
Ionic crystal generates molecular ions upon positron irradiation
The positron, the antiparticle of the electron, has the same mass and charge as that of an electron but with the sign flipped for the charge. It is an attractive particle for scientists because the use of positrons has led to important insights and d.....»»
Titanium oxide material can remove toxic dyes from wastewater
Discharged in large quantities by textile, cosmetic, ink, paper and other manufacturers, dyes carry high-toxicity and can bring potential carcinogens to wastewater. It's a major concern for wastewater treatment—but researchers in Drexel University'.....»»
Chemists create sensors to track potassium and sodium in cell organelles
Two studies by scientists at the University of Chicago have demonstrated a new way to look into the inner workings of cells—in particular, to track the flow of ions inside the many tiny organelles inside the cell......»»
BSI-AST chip: A powerful tool to accelerate antimicrobial susceptibility testing for bloodstream infections
The presence of viable bacteria in the blood (bacteremia) when not controlled properly can lead to bloodstream infection (BSI) and sepsis, a syndromic inflammatory response......»»
Lethal weapon: New antimicrobial coating could revolutionize cleaning methods
We've gained a new weapon in the fight against harmful and often antibiotic-resistant pathogens with the development of a unique material engineered to limit disease spread and replace current cumbersome cleaning protocols on high-touch surfaces like.....»»
Genomics detective work reveals pest moth travels
The fall armyworm moth (Spodoptera frugiperda) is a notorious pest in agriculture. It devastates essential food crops and threatens global food security. It has been reported to feed on more than 350 plant species, ranging from maize to cotton and ve.....»»
Innovative solution for poultry litter waste management uses photocatalytic titanate nanofibers
The shift away from using poultry litter for crop fertilization has transformed this once-valuable agricultural byproduct into an environmental liability for poultry producers. Addressing this challenge, a study led by Dr. Jun Zhu from the University.....»»
Autopsy of a star reveals what was eviscerated by a monster black hole
From the interior of a star to the accretion disk of a black hole. Enlarge / Ions of nitrogen and carbon show up in the spectrum of X-rays from a black hole's accretion disk. (credit: NASA/Chandra) Even huge stars are no.....»»
Converting plant wastes into antimicrobial agents that could prevent pathogenic infections
Nebraska researchers are converting plant wastes into antimicrobial agents that could help prevent pathogenic infections and death while significantly lowering the cost of antimicrobial treatments and being a boon to the bioeconomy......»»
Novel device combines nanopores with electronic signals for disease detection
In living organisms, cells have a very high capacity to process and communicate information by moving molecules or ions through tiny channels that span the cell membrane. UC Santa Cruz Professor of Electrical and Computer Engineering Marco Rolandi's.....»»
Environmental scientist conducts international research on the impacts of cotton
Cotton is the most widely used natural fiber for clothes. But how polluting are our jeans and shirts actually? Environmental scientist Laura Scherer has coordinated an international research project on the impacts of cotton. The study is published in.....»»
