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.....»»
Who Tests If Heat-Proof Clothing Actually Works? These Poor Sweating Mannequins
These mannequins undergo daily torture at the hands of textile scientists, but their suffering means we humans can have future-proofed clothing capable of handling our warming world......»»
Scientists develop new molecular system made from abundant element manganese for photooxidation
Highly reducing or oxidizing photocatalysts are a fundamental challenge in photochemistry. Only a few transition metal complexes with Earth-abundant metal ions have so far advanced to excited state oxidants, including chromium, iron, and cobalt. All.....»»

An interdisciplinary team of Cornell researchers has identified an innovative way to harness the antioxidant and antibacterial properties of the botanical compound lawsone to make nanofiber-coated cotton bandages that fight infection and help wounds.....»»
New research highlights implications of antibiotic use in human and veterinary medicine
A series of five research publications on Antimicrobial Resistance (AMR) by APC Microbiome Ireland yields new data regarding the implications of antibiotic use in early life and the effects of antibiotics in standard dry cow therapy......»»
New insights into how epilancin 15X kills bacteria
Antimicrobial resistance has emerged as a global threat that requires urgent attention. In a new study published in Frontiers in Microbiology, researchers have investigated how the antibiotic epilancin 15X kills bacteria......»»
Ultra-sensitive lead detector could significantly improve water quality monitoring
Engineers at the University of California San Diego have developed an ultra-sensitive sensor made with graphene that can detect extraordinarily low concentrations of lead ions in water. The device achieves a record limit of detection of lead down to.....»»
Deep learning reveals molecular secrets of explosive perchlorate salts
Perchlorates are a class of compounds that are notorious for their explosive nature. This raises safety concerns during experiments involving complex compounds that contain perchlorate ions, since explosions can be triggered even by the slightest sho.....»»
New design improves water decontamination via plasma jet
Plasma is an ionized gas—that is, a gas containing electrons, ions, atoms, molecules, radicals, and photons. It is often called the fourth state of matter, and surprisingly, it permeates everything. Plasmas, which are artificially generated by tran.....»»
Unveiling sodium channel dynamics: New insights into cell biology using high-speed atomic force microscopy
The transport of ions to and from a cell is controlled by pore-forming proteins embedded in the cell membrane. In particular, voltage-gated sodium channels (VGSCs) govern the transfer of sodium (Na+) ions, and play an important role in the regulation.....»»
Researchers visualize energetic ion flow in fusion devices
In a burning plasma, maintaining confinement of fusion-produced energetic ions is essential to producing energy. These fusion plasmas host a wide array of electromagnetic waves that can push energetic ions out of the plasma......»»
Elucidating the biosynthetic mechanism for protoberberine alkaloids from Coptis chinensis
Protoberberine alkaloids are a group of tetracyclic isoquinoline compounds known for their well-established antimicrobial and anti-inflammatory properties. Although protoberberine alkaloids are broadly found in various plant families such as Ranuncul.....»»
Study finds 90% of textile waste generated in Catalonia ends up in landfill or incinerators
A total of 90% of the municipal textile waste generated in Catalonia ends up in landfills or incinerators, according to a study by ICTA-UAB, which shows that only 10% of textile waste is collected separately. In the case of Catalonia, this percentage.....»»
New research deciphers biomineralization mechanism
Many organisms can produce minerals or mineralized tissue. A well-known example is nacre, which is used in jewelry because of its iridescent colors. Chemically speaking, its formation begins with a mollusk extracting calcium and carbonate ions from w.....»»
Size and shape of inhaled asbestos nanofibers may be exclusively responsible for pulmonary fibrosis
The pathogenic potential of inhaling the inert fibrous nanomaterials used in thermal insulation (such as asbestos or fiberglass) is actually connected not to their chemical composition, but instead to their geometrical characteristics and size. The r.....»»
Scientists solve mystery of how predatory bacteria recognizes prey
A decades-old mystery of how natural antimicrobial predatory bacteria are able to recognize and kill other bacteria may have been solved, according to new research......»»
Novel approach uses ionic liquids for diverse aptamer applications
Aptamers, nucleic acids capable of selectively binding to viruses, proteins, ions, small molecules, and various other targets, are garnering attention in drug development as potential antibody substitutes for their thermal and chemical stability as w.....»»
