A Novel Approach to Produce Metal–Metal Composites by Leveraging Immiscibility: Laser Powder Bed Fusion of Nanosilver‐Dispersed Titanium

Advanced Engineering Materials, EarlyView.
Incorporating nanosized silver into titanium for antimicrobial materials exploits the metastable miscibility gap between silver and titanium. Silver nanoparticles are synthesized via pulsed laser ablation in liquid. Silver addition refines the microstructure, increases hardness by 30%, and reduces Staphylococcus capitis microbial adhesion by 70%, with ...

In silico approaches of gandarusa (Justicia gendarussa Burm. f.) potential for osteoporosis prevention via EGF pathway [PDF]

Journal of Pharmacy & Pharmacognosy Research
Context: On a cellular level, osteoporosis is a metabolic bone disease caused by osteoclastic bone resorption that is not offset by osteoblastic bone synthesis. This increases the risk of fractures by making bones weak and brittle.
