MIL-53(Al) based magnetic framework composites with iron oxide nanoparticles exhibit high uptake of lead(<sc>ii</sc>) from aqueous solution.
The incorporation of highly luminescent core-shell quantum dots (QDs) within a metal-organic framework (MOF) is achieved through one-pot method. Through appropriate surface functionalization, the QDs are solubilized MOF-5 growth media. This permits evolving during reaction. resulting QD@MOF-5 composites characterized using X-ray fluorescence, cross-sectional confocal microscopy, energy-dispersive spectroscopy, scanning electron and small-angle scattering. synergistic combination controlled...
Abstract Scaffolds with gradients of physico-chemical properties and controlled 3D architectures are crucial for engineering complex tissues. These can be produced using multi-material additive manufacturing (AM) techniques. However, they typically only achieve discrete separate printheads to vary compositions. Achieving continuous composition gradients, better mimic tissues, requires material dosing mixing controls. No such AM solution exists most biomaterials. Existing techniques also...
Bone infections following open bone fracture or implant surgery remain a challenge in the orthopedics field. In order to avoid high doses of systemic drug administration, optimized local antibiotic release from scaffolds is required. 3D additive manufactured (AM) made with biodegradable polymers are ideal support healing non-union scenarios and can be given antimicrobial properties by incorporation antibiotics. this study, ciprofloxacin gentamicin intercalated interlamellar spaces magnesium...
The template method for preparing nanomaterials entails synthesis of tubular or fibrillar nanostructures within the pores a microporous membrane. If holes are completely filled, solid nanowires result, while partial filling with continuous coating gives rise to nanotubes.
