Synthesis and Some Colloidal Properties of Hydrosols Prepared by the Hydrolysis of Copper(II) Nitrate

Hollow Microtubes and Shells from Reactant‐Loaded Polymer Beads

“…In the context of this simple scaling argument, we can now interpret the value of the constant k as approximately 3 w c s . For a width of about 1 μm, this expression yields concentrations c s in the range of 3–10 M , which is in reasonable agreement with the expected values 12. We emphasize that we have disregarded reaction‐induced concentration gradients within the bead.…”

“…For a width of about 1 mm, this expression yields concentrations c s in the range of 3-10 m, which is in reasonable agreement with the expected values. [12] We emphasize that we have disregarded reaction-induced concentration gradients within the bead. However, this simplification might be acceptable as the diffusion time The detailed time-dependence of the growth velocity suggests that bubble-guided tube growth often occurs in two distinct stages.…”

Vapor Phosphorylation of Cellulose by Phosphorus Trichlo-Ride: Selective Phosphorylation of 6-Hydroxyl Function—The Synthesis of New Antimicrobial Cellulose 6-Phosphate(III)-Copper Complexes

“…Lower ZOI values of the composites Cell-O 6 -P(O)(O − )-H × Cu 2+ in comparison with ZOI of soluble copper salts/nanoparticles is caused by a strong binding of copper ions by the functionalities of Cell-O 6 -P(O)(OH)-H, namely by hydrogen-phosphate (III) function, and also by surrounding cellulose hydroxyls. This results in a slow release of copper from the surface of composite, presumably driven by a hydrolysis [85][86][87], which limits a concentration of unbounded Cu (II) cations (Figure 19). and also by surrounding cellulose hydroxyls.…”
