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.....»»
RHIC gets ready to smash gold ions for Run 23
The start of this year's physics run at the Relativistic Heavy Ion Collider (RHIC) also marks the start of a new era. For the first time since RHIC began operating at the U.S. Department of Energy's Brookhaven National Laboratory in 2000, a brand new.....»»
Researchers construct non-interpenetrated 3D covalent organic framework for Au ions capture
Covalent organic frameworks (COFs) can be an ideal platform for detecting or extracting metal ions due to their different functional building units and large surface area......»»
How do Candida auris and other fungi develop drug resistance? A microbiologist explains
One of the scariest things you can be told when at a doctor's office is "You have an antimicrobial-resistant infection." That means the bacteria or fungus making you sick can't be easily killed with common antibiotics or antifungals, making treatment.....»»
Upcycling method turns textile trash to functional coatings
In an effort to make textiles more sustainable, a new method allows researchers to break old clothing down chemically and reuse polyester compounds to create fire resistant, anti-bacterial or wrinkle-free coatings that could then be applied to clothe.....»»
Differing device personalities come together for future quantum computing networks
We're building the tools to trap ions and watch them glow (or not). The art-deco-esque device shown above is a combined trap for ions (charged atoms) and detector for individual photons (particles of light). When you hold an ion in place and hit it w.....»»
Super-charged textile repairs itself, monitors heart rhythm
Scientists from around the world have developed a simple metallic coating treatment for clothing or wearable textiles which can repair itself, repel bacteria from the wearer and even monitor a person's electrocardiogram (ECG) heart signals......»»
Newly discovered electrical activity within cells could change the way researchers think about biological chemistry
The human body relies heavily on electrical charges. Lightning-like pulses of energy fly through the brain and nerves and most biological processes depend on electrical ions traveling across the membranes of each cell in our body......»»
Researchers create antimicrobial "superfoam"
A versatile new foam material developed by researchers at the University of Georgia could significantly reduce health care-related infections caused by implanted medical devices—or drastically improve cleanup efforts following environmental disaste.....»»
Functional textiles: An alternative to antibiotics
Tuser Biswas conducts research that aims to develop modern medical textiles that are good for both the environment and human health. Textiles with antimicrobial properties could reduce the use of antibiotics. On February 28, Tuser Biswas defended his.....»»
Getting purer berkelium, faster than ever
Researchers need a better way to extract individual heavy metal elements, called actinides, to obtain a purer product. In 2018, researchers discovered that the actinide berkelium, when oxidized, does not form negatively charged ions in solutions of h.....»»
After decades of lurking, an elusive bacterium finally strikes in California
California man is first to have a confirmed B. miyamotoi infection in western US. Enlarge / This highly magnified scanning electron microscopic (SEM) image depicts a number of spirochete bacteria, atop a culture of cotton-tail ra.....»»
Migrating ions through the perovskite layer in two dimensions
Electrostatic doping has been widely used in low-dimensional materials, including carbon nanotube (CNT) and two-dimensional (2D) materials such as graphene and transition metal dichalcogenides (TMDs). Unlike conventional lattice doping with impurity.....»»
A fiber-tapering technique that combines plasmonic heaters and deformed optical fibers
Optical micro and nanofibers (MNFs) have extensive applications in nonlinearity generation, near-field optics, quantum optics, and miniaturized sensing. Although MNFs have fostered the development of various disciplines, there have been few studies o.....»»

Katie Cotton, Apple’s influential PR chief during Steve Jobs era, has passed away
Katie Cotton was best known for leading Apple’s public relations in the Steve Jobs era for over 20 years. 9 years after retiring from her position at Apple, Cotton passed away on Thursday, April 6, 2023. more… The post Katie Cotton, Apple’.....»»
Hot electron electrochemistry with ultrafast laser pulses
Laser-induced electrochemical deposition of metals on metals relies possibly on thermal and defect generation effects. When semiconductor substrates are chosen, locally photogenerated electrons can reduce metal ions resulting in metallic surface stru.....»»
Highly charged ions melt nano gold nuggets
Normally, we have to make a choice in physics: Either we deal with big things—such as a metal plate and its material properties, or with tiny things—such as individual atoms. But there is also a world in between: The world of small but not yet ti.....»»
Human body is a breeding ground for antimicrobial resistance genes, shows new study
The community of microbes living in and on our bodies may be acting as a reservoir for antibiotic resistance, according to new research from the Earlham Institute and Quadram Institute in Norwich. The work is published in the journal Nature Communica.....»»
Oxygen groups key to unlocking graphene"s antimicrobial potential, say scientists
The amount of surface oxygen in graphene materials is a key factor in how effective they could be in killing bacteria—a discovery which may help to design safer and more effective products to combat antimicrobial resistance......»»
