Tracking the atomic pathways of Pt3Ni-Ni(OH)2 core-shell structures at the gas-liquid interface by in-situ liquid cell TEM

Using melamine formaldehyde (MF) microspheres as hard templates and silica colloid as shell precursors, core-shell structures of silica-coated MF microspheres were prepared by the electrostatic adsorption process or spray drying inspired in-situ coating and drying process. Furthermore, nanometer- and micrometer-sized silica hollow spheres were obtained by calcinations in air. The influence of preparation methods and ratio of silica colloid to MF microspheres on the composition, the morphology and size of the core-shell intermediates and the hollow spheres were studied with FTIR, SEM and TEM techniques.

New Strategies

Naturally inspired biomaterials such as calcium carbonate, produced in biological systems under specific conditions, exhibit superior properties that are difficult to reproduce in a laboratory. The emergence of microfluidic technologies provides an effective approach for the synthesis of such materials, which increases the interest of researchers in the creation and investigation of crystallization processes. Besides accurate tuning of the synthesis parameters, microfluidic technologies also enable an analysis of the process in situ with a range of methods. Understanding the mechanisms behind the microfluidic biomineralization processes could open a venue for new strategies in the development of advanced materials. In this review, we summarize recent advances in microfluidic synthesis and analysis of CaCO3-based bioinspired nano- and microparticles as well as core-shell structures on its basis. Particular attention is given to the application of calcium carbonate particles for drug delivery.
