The present research aims to develop a Ca-Zn ion-incorporated surface functionalized 3D Ti cancellous bone scaffold for bone defect repair. The scaffold is designed to mimic human cancellous bone architecture through selective laser melting-based additive manufacturing. The chemical-based surface modification approach employed here created a Ca and Zn ions incorporated nano-porous surface layer with enhanced surface roughness and hydrophilicity.

Among the promising candidates, hierarchical inorganic nanostructures stand out due to their exceptional attributes, including a high specific surface area, abundant active sites, and tunable optoelectronic properties. In this comprehensive review, we delve into the fundamental principles underlying various solar energy harvesting technologies, including dye-sensitized solar cells (DSSCs), photocatalytic, photoelectrocatalytic (water splitting), and photothermal (water purification) systems, providing a foundational understanding of their operation.

Detection of carbapenemase activity helps to understand the possible mechanism(s) of carbapenem resistance. Identification of carbapenemases is currently being done by various phenotypic methods and molecular methods.

Aetiology of obesity is associated with mechanisms such as short chain fatty acid production, stimulation of hormones, chronic low‑grade inflammation, lipoprotein and bile acid metabolism and increased endocannabinoid. Receptor system tone have been suggested to explain the role of gut microbiota of obesity.
