Many of the advances in material performance over the last decade can be attributed to developments in multicomponent polymer systems and specifically, to multiphase materials such as incompatible polymer blends and fibre-reinforced composites. In these types of material, performance properties are often dominated by the interphase that defines the transition region from one pure phase to anoth...
The polyol method has been widely employed for the synthesis of uniform silver nanowires (Ag NWs) in high yields. In this article, we describe the utilization of HCl oxidative etching as an effective strategy to control the width of Ag NWs produced by the polyol approach. More specifically, the width of the produced Ag NWs could be tuned from 65 to 765 nm by varying the HCl concentration in the...
Novel polyols were synthesized by controlled polymerization of hydroxylated fatty acids from methyl soyate. Polymerization of methyl esters of hydroxy fatty acids gives a hyperbranched (HB) product with different content of hydroxyl groups depending on the degree of conversion. Molecular weights, functionality and hydroxyl equivalent of polyols can be controlled by controlling the degree of con...
Plasma clearance of D-sorbitol, a nontoxic polyol, occurs predominantly in the liver and has been used to measure functional liver blood flow after bolus and steady- state intravenous administration. However, it is not known which of these two administration methods is superior. Therefore, plasma D-sorbitol clearance was studied in an animal model both after a bolus dose and under steady-state ...
The copolymerization of epoxides, including cyclohexene oxide and vinyl-cyclohexene oxide with carbon dioxide are presented. These processes are catalyzed using a homogeneous di-zinc complex that shows good activity and very high selectivities for polycarbonate polyol formation. The polymerizations are investigated in the presence of different amounts of exogenous reagents, including water, dio...
CoO submicrometer-sized pseudo-single crystals were produced in polyol thanks to an oriented aggregation crystal growth driven by the molecules themselves.
We adsorb heavy metal ions such as Ag(+), Pb(2+), and Ru(3+) onto an aquatic plant and convert the adsorbed ions to the corresponding nanometallic particles by the polyol reaction carried out in a microwave oven.
Hollow vanadyl glycolate nanostructured microspheres were synthesized via a highly scalable and template-free polyol-induced solvothermal process. Subsequent calcination transformed the precursor material into vanadium pentoxide, a well-studied transition metal oxide. The vanadyl glycolate nanoparticles were synthesized through a self-seeding process and then aggregated around N2 microbubbles f...
