source:AZO MATERIALSThe Covid-19 pandemic has demonstrated the urgent need for antiviral and antimicrobial coatings for surfaces in public spaces and healthcare environments. Recent research published in October 2021 in the journal Microbial Biotechnology has demonstrated a rapid nano-Zinc oxide doped preparation for polyurea coatings that seeks to address this issue.The Need for Hygienic SurfacesAs demonstrated by multiple outbreaks of communicable diseases, surfaces are a source of pathogen transmission. The pressing need for rapid, effective, and non-toxic chemicals and antimicrobial and an...

source:Concordia universityA new kind of metal–organic framework created in the Howarth Lab can rapidly break down sulfur mustardResearchers at Concordia are studying the potential applications of a type of compound called metal–organic frameworks (MOFs). They have designed a new kind of microscopic structure that can rapidly mitigate chemical weapons when exposed to ultraviolet light.MOFs are artificially created hybrid networks of metal clusters bound to each other by organic linkers called ligands. They are usually open-faced and porous, sometimes described as sponge-like. They are extremel...

source:ENGINEERLIVEEriez has built and commissioned what it believes is the world’s first 80-inch dry high intensity rare earth (RE) roll magnetic separator to satisfy unique minerals processing application requirements, according to director of Minerals and Materials Processing, Jose Marin. The rare earth roll magnetic separator was successfully installed at the customer’s site, and preliminary findings indicate the industrial mineral upgraded by the equipment has “exceeded the expectations of the customer, even at higher than specified feed rates,” Marin reports.Eriez rare earth roll magneti...

source:PhysicsworldResearchers in Japan have built the first nuclear magnetic resonance (NMR) magnet that incorporates high-temperature superconductors with truly superconducting joints between them. This breakthrough all-superconducting configuration enables the device to operate at relatively high magnetic fields in so-called persistent mode, making it suitable for applications such as maglev trains and magnetic resonance imaging (MRI). The new device might also serve as a stepping-stone towards persistent-mode magnets that work at even higher magnetic fields, without the need for liquid hel...
