We believe that our method would be powerful approach to various microscale biochemical applications including soft actuators/sensors and scaffolds for cells. Using this feature, we successfully demonstrated various types of hydrogel microsprigs encapusulating functional materials. Nanoparticles for CO2 Photoreduction, ChemSusChem, vol. We found that the microspring formation mainly depends on the rapid anisotropic-gelation of thin outer calcium alginate hydrogel, regardless of the properties of core materials. Tan, JZY, Xia, F & Maroto-Valer, MM 2019, Raspberry-Like Microspheres of CoreShell Cr2O3TiO2. Core-shell hydrogel microsprings were spontaneously assembled by using a bevel-tip capillary with coaxial-la minar flow: the outer flow is sodium a lginate solution and the inner f low contains functional materials. We believe that our method would be powerful approach to various microscale biochemical applications including soft actuators/sensors and scaffolds for cells.ĪB - This paper describes core-shell hydrogel microsprings that encapsulate various functional materials inside. Two syringe pumps (KD Scientific, Holliston, MA) deliver the polymer solution at a specific rate into the outer and inner capillary of coaxial needle. Using this feature, we successfully demonstrated various types of hydrogel microsprigs encapusulating functional materials. The core capillary presents a 0.40 mm outer diameter and a 0.20 mm inner diam - eter and the outer capillary has a 0.72 mm in outer diameter and a 0.50 mm in inner diame-ter. An ultrasensitive and highly reproducible novel surface-enhanced Raman scattering (SERS)-enabled capillary platform was developed for on-site detection of. We found that the microspring formation mainly depends on the rapid anisotropic-gelation of thin outer calcium alginate hydrogel, regardless of the properties of core materials. Titanium dioxide-coated core-shell silica microspheres-based solid-phase extraction combined with sheathless capillary electrophoresis-mass spectrometry for. Core-shell hydrogel microsprings were spontaneously assembled by using a bevel-tip capillary with coaxial-la minar flow: the outer flow is sodium a lginate solution and the inner f low contains functional materials. The Fe3O4ZIF-8 microspheres as catalysts could be easily filled into a capillary microreactor with the help of an external magnetic field.

The microreactor demonstrates excellent catalytic activity at a shorter residence time for Knoevenagel condensation reaction of benzaldehyde and ethyl cyanoacetate. Preparation of micron-sized monodispersed thermoresponsive core-shell. The microspheres as catalysts could be easily filled into a capillary microreactor with the help of an external magnetic field. Capillary mechanisms in membrane emulsification: oil-in-water emulsions. The procedure involves first pre-treating the magnetic cores with an anionic polyelectrolyte to alter the surface charge of the particles and adsorb Zn2+ cations to initiate nucleation and then growing a thin layer of ZIF-8 to form a highly reactive, magnetic core-shell microsphere The characterization by various techniques indicates that ZIF-8 shell is continuous and has an average thickness of around 100 nm. 398-404Ī facile synthesis strategy for preparing magnetic core-shell microspheres has been successfully developed. Kong, Capillary micromechanics for coreshell particles, Soft Matter, 10. The inner phase of the Na-ALG solution flows inside the inner. In a typical experiment, a coaxial capillary microfluidic system with an inner injection channel and an outer reaction channel is used for the continuous generation of microfibers, as illustrated schematically in Fig. Please use this identifier to cite or link to this item: Synthesis of magnetic core-shell microspheres and their potential application in a capillary microreactor Bibliographic Details AuthorĬhemical Engineering Journal, v.
