E. coli imprinted nano-structured silica micro-granules by spray drying: Optimization of calcination temperature

Porous nano-structured micro-granules from silica-milk bi-colloidal suspension: Synthesis and characterization

“…The granules, thus formed, are stable under moderate heat or pressure applications. It has been reported earlier [32] that only by heating beyond 500 • C, the individual silica nanoparticles start coalescing, however, there is no significant change in structural correlation below this temperature. In the present case, we have kept the calcination temperature at 450 • C, so that the jammed nano-particles stay intact in the granule.…”

“…Needless to say, such aerosol drying method can be implemented for bi-colloidal suspension (i.e., stable mixture of two colloids) to obtain composite nano-structured granules [26]. Removal of one of the components from such two component system would ultimately form porous granule [32] having interlocked correlated nano-particles as the skeleton.…”

Synthesis of spherical microscale and nanoscale modified silica particles using spray-drying and spray-pyrolysis process

“…It was measured at about 50°C. Thanks to the capillarity forces [16], colloidal particles are dragged towards each other's to form the final product which will be collected by a collector after passing from the cyclone which allow its separation to the gas. The powder is stored into desiccator at room temperature before being analyzed.…”

“…It consists in solvent evaporation spraying atomized droplets into a high temperature chamber to produce dry powder with controlled size. The main drawback of this method was the polydispersity droplets obtained with conventional spray-drying which can be eliminated by the use of a two fluid nozzle which produce monodispersed droplets [5]. Spray-Pyrolysis technique is widely used to synthesize dense solid such as ceramics [6][7].…”

Facile and controllable one-step fabrication of molecularly imprinted polymer membrane by magnetic field directed self-assembly for electrochemical sensing of glutathione

“…MIPs have been recognized as artificial recognition materials, which possess binding sites complementary in size and shape to templates for specific recognition of target molecules [24][25][26]. Besides excellent recognition property, MIPs, especially nano-structured MIPs, have several advantages over their biological counterparts including low cost, easy preparation, durability to heat and pressure, storage stability and high rebinding capacity [27][28][29]. However, MIES typically suffers from low sensitivity, since MIPs are lack of conductivity and electrocatalytical activity [30,31].…”
