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.....»»
Practical nanozymes discovered to fight antimicrobial resistance
Nanozymes, a group of inorganic catalysis-efficient particles, have been proposed as promising antimicrobials against bacteria. They are efficient in killing bacteria, thanks to their production of reactive oxygen species (ROS)......»»
Diphtheria risks becoming major global threat again as it evolves antimicrobial resistance
Diphtheria - a relatively easily-preventable infection - is evolving to become resistant to a number of classes of antibiotics and in future could lead to vaccine escape, warn an international team of researchers......»»
Humidity in breath makes cotton masks more effective at slowing the spread of COVID-19
Researchers have come up with a better way to test which fabrics work best for masks that are meant to slow the spread of COVID-19. By testing those fabrics under conditions that mimic the humidity of a person's breath, the researchers have obtained.....»»
Tantalizing signs of phase-change "turbulence" in RHIC collisions
Physicists studying collisions of gold ions at the Relativistic Heavy Ion Collider (RHIC), a U.S. Department of Energy Office of Science user facility for nuclear physics research at DOE's Brookhaven National Laboratory, are embarking on a journey th.....»»
X-ray microscopy reveals the outstanding craftsmanship of Siberian Iron Age textile dyers
The Pazyryk carpet is the world's oldest example of a knotted-pile carpet and is kept at the State Hermitage Museum in St. Petersburg, Russia. The carpet, which was made out of new wool at around 400 BC, is one of the most exciting examples of centra.....»»
Simulations to make insight into electrokinetic transport more reliable
Researcher Remco Hartkamp and Ph.D. student Max Döpke of the Process & Energy Department have taken an important step in making simulation results for electrokinetic transport more reliable by using molecular simulations. In electrokinetics, ions pl.....»»
3-D images of fabric "sandwich" can help measure textile friction
To quantify exactly how itchy a wool sweater might be when worn directly against the skin, or how soft a blanket spread on your bed can be, North Carolina State University researchers developed a method of measuring fabric's roughness using 3-D imagi.....»»
New study challenges "established" mechanism about selectivity of cellular ion channels
The cell membranes of all organisms contain ion channels that permit ions to pass into or out of the cell, and these channels play extremely important roles in fundamental physiological processes such as heartbeats and the rapid conduction of signals.....»»
Recycled cotton becomes new fabric
A lot of us recycle our old textiles, but few of us know that they are very difficult to re-use, and often end up in landfills anyway. Now, researchers at Lund University in Sweden have developed a method that converts cotton into sugar, that in turn.....»»
Steel and wool Cornucopia vases are designed to outshine the flowers they hold
Textile design duo Röd Studio has collaborated with Copenhagen studio Tableau to create a series of steel and wool vases informed by the art of pastry decoration. Read more Textile design duo Röd Studio has collaborated with Copenhagen stu.....»»
Application of potassium to grass used as cover crop guarantees higher-quality cotton
The use of cover crops between cotton harvests protects the soil, conserves water, and reduces the risk of erosion. Researchers at the University of Western São Paulo (UNOESTE) and São Paulo State University (UNESP) in Brazil found that application.....»»
Creating a highway tunnel for ions
We live in modern times, that is full of electronics. Smartphones, laptops, tablets, and many other devices need electrical energy to operate. Portable devices made our lives easier, so novel solutions in clean energy and its storage are desirable. L.....»»
Plant-based magnetic nanoparticles with antifungal properties
A team of researchers from Immanuel Kant Baltic Federal University obtained magnetic nanoparticles using sweet flag (Acorus calamus). Both the roots and the leaves of this plant have antioxidant, antimicrobial, and insecticide properties. The extract.....»»
Multi-inch single-crystalline perovskite for self-powered integrated circuit photodetection reported
Multiple-cation and mixed-halide (FAMACs) perovskites, which are formed by incorporating Cs/MA/Br ions into the FAPbI3 perovskites, are considered as the best compositions for applications in high-efficiency photovoltaic and photoelectronic devices o.....»»
Nanotech plastic packaging could leach silver into some types of foods and beverages
Antimicrobial packaging is being developed to extend the shelf life and safety of foods and beverages. However, there is concern about the transfer of potentially harmful materials, such as silver nanoparticles, from these types of containers to cons.....»»
Ýrúrarí uses knitted body parts to give clothes a character of their own
Textile designer Ýrúrarí, who is nominated for this year's Icelandic Design Award, gives new life to worn-out clothes by adding playful knitted details such as eyes, tongues and fingers. Read more Textile designer Ýrúrarí, who is nomin.....»»
Invasive evergreen acutely reduces water resources in Ethiopia, costing rural livelihoods
New research has revealed how an invasion of the evergreen tree Prosopis juliflora seriously diminishes water resources in the Afar Region of Ethiopia, consuming enough of this already scarce resource to irrigate cotton and sugarcane generating some.....»»
Researchers develop software to find drug-resistant bacteria
The program could make it easier to identify the deadly antimicrobial resistant bacteria that exist in the environment. Such superbugs annually cause more than 2.8 million difficult-to-treat pneumonia or bloodstream infections and 35,000 deaths in th.....»»
Ions in molten salts can "go against the flow"
In a new article published in the scientific journal Communications Chemistry, a research group at Uppsala University show, using computer simulations, that ions do not always behave as expected. In their research on molten salts, they were able to s.....»»
Researchers construct molecular nanofibers that are stronger than steel
Self-assembly is ubiquitous in the natural world, serving as a route to form organized structures in every living organism. This phenomenon can be seen, for instance, when two strands of DNA—without any external prodding or guidance—join to form.....»»
