source:AZO materialsMg-based Biomaterials in Orthopedic TreatmentMagnesium (Mg) is an essential mineral for humans and animals. Humans need about 250-350 mg of Mg on a daily basis, out of which a major portion is excreted through the gastrointestinal (GI) tract and renal system. Meanwhile, about 70-180 mg of it is absorbed by the human body for cellular fluids, kidneys, and bones. Mg is both biocompatible and biodegradable in the human body that promotes bio-responses at cellular and molecular levels.Orthopedic implants are used to compensate for bone or soft tissue losses due to traumas, canc...

source:PhysicsThe COVID-19 pandemic threw a wrench in supply chains for many materials, including those used to make magnets. Magnets are crucial components in technologies ranging from computer hard-disk drives to magnetic resonance imaging scanners. To circumvent such disruptions, researchers are looking into alternative ways to source magnetic materials. Daniel Casaleiz of IMDEA Nanoscience, Spain, shared the details of one such method at the recent 2022 Joint Magnetism and Magnetic Materials (MMM) - Intermag conference, which took place online and in New Orleans in January.Casaleiz and his...

source:LaserFocusWorld group of researchers at Hokkaido University’s Institute for Chemical Reaction Design and Discovery in Japan combined blue light-emitting diodes (LEDs) with a copper-based molecular catalyst to create a more sustainable way to make chemical subunits (single molecules that assemble with others to form a complex)—with potential applications in pharmaceutical and photoelectronic development.The blue LED and copper-based molecular catalyst combo generates a cross-coupling reaction, in which two molecules are joined via a carbon-carbon bond. It’s a widely used type of rea...
