Modeling of adsorption phenomena was carried out for core-shell adsorbents with spherical, cylindrical, and slab-type morphologies. Numerical solutions adsorbates in the adsorber could be obtained as a function time by solving coupled diffusion equations to take account inert-core thickness (x’). Transient responses batch continuous adsorbers containing were predicted, assuming rectangular or L...

porous hollow glass microspheres have many uses, including encapsulation of active materials. in this paper a fast and facile method for fabricating porous hollow glass-microspheres was demonstrated by etching them using dilute hydrofluoric acid. then, a highly reactive amine was infiltrated into the etched glass microspheres. scanning electron microscopy was conducted for the hollow glass micr...

BACKGROUND Schistosoma mansoni and Schistosoma japonicum are the most frequent causative agents of human intestinal schistosomiasis. Approximately 200 million people in the world are infected with schistosomes. Diagnosis of schistosomiasis is often difficult. High percentages of low level infections are missed in routine fecal smear analysis and current diagnostic methodologies are inadequate t...

Silicon microsphere photodiodes constitute optoelectronic devices able to provide resonance-enhanced photocurrent not only in the visible but also near infrared range by virtue of their associated Mie resonances. They are synthesized means a bottom-up process that allows obtaining thousand single batch. The microspheres have revealed an internal structural configuration strongly influences resp...

Zinc sulfide films were grown on carboxyl-modified polystyrene microspheres (PS-CO2) through sonochemical deposition in an aqueous bath containing zinc acetate and sulfide, released through the hydrolysis of thioacetamide. The resulting particles were “optically hollow”, due to a large refractive index contrast between the core and shell materials. Continuous, uniform films were obtained after ...

Coating hydrogel films or microspheres by an adsorbed colloidal shell is one synthesis method for forming colloidosomes. The colloidal shell allows control of the release rate of encapsulated materials, as well as selective transport. Previous studies found that the packing density of self-assembled, adsorbed colloidal monolayers is independent of the colloidal particle size. In this paper we d...

Three kinds of N-doped mesoporous TiO₂ hollow spheres with different N-doping contents, surface area, and pore size distributions were prepared based on a sol-gel synthesis and combined with a calcination process. Melamine formaldehyde (MF) microspheres have been used as sacrificial template and cetyltrimethyl ammonium bromide (CTAB) or polyvinylpyrrolidone (PVP) was selected as pore-directing ...

nano-hydroxyapatite/gelatin (nha/ge) microspheres are currently used in bone tissue engineering as bone filler. in this  study, the effect of fabrication process parameters on the particle size of nano-hydroxyapatite/gelatinmicrospheres was investigated. the nha/ge microspheres were fabricated using water in oil emulsion. in order to design an experimental design, a surface response model with ...

       The cellular therapy and nerve tissue engineering will probably become a major therapeutic strategy for promoting axonal growth through injured area in central nervous system and peripheral nervous system in the coming years. The stem cell carrier scaffolds in nerve tissue engineering resulted in strong survival of cells and suitable differentiation into n...
