Amphiphilic Block Copolymer Micelles in Selective Solvents: The Effect of Solvent Selectivity on Micelle Formation

“…Such micelles comprising an inner PS core and outer P4VP corona can be obtained with the aid of P4VP-selective solvents, for instance, alcohols. Alcoholic PS- b -P4VP micellar solutions are particularly attractive for the synthesis of various polymer-inorganic core–shell, yolk–shell particles, or hollows particles, by exploring advantages of sol-gel processes [16,17,18]. Although the strong affinity of alcohols toward P4VP is known from the literature [11], to the best of our knowledge, there has been no effort to understand the effect of solvent on the PS- b -P4VP micellization process taking place in different alcohols.…”

Shedding light on precursor and thermal treatment effects on the nanostructure of electrospun TiO2 fibers

“…To further improve the properties of TiO 2 and to expand potential applications, low-dimensional nanostructures with controllable crystalline phases, such as nanoparticles, nanofibers, nanostructured thin films or coatings and nanotubes have been extensively studied. In particular, TiO 2 microtubes constituted by defined nanoscale particles have attracted considerable attention [11][12][13][14][15][16].…”

Hollow Au@TiO2 porous electrospun nanofibers for catalytic applications

“…5). 36,37 The combination of HAADF-STEM imaging and EDX-based element mapping clearly showed the presence of AuNPs trapped in the titania shell of the nanobers. Furthermore, the HRTEM image shown in Fig.…”
