Correlated effects of selection for components of litter size on growth and backfat thickness were estimated using data from 3 pig lines derived from the same base population of Large White. Two lines were selected for 6 generations on either high ovulation rate at puberty (OR) or high prenatal survival corrected for ovulation rate in the first 2 parities (PS). The third line was an unselected ...
This Perspective presents recent advances in macromolecular engineering enabled by ATRP. They include the fundamental mechanistic and synthetic features of ATRP with emphasis on various catalytic/initiation systems that use parts-per-million concentrations of Cu catalysts and can be run in environmentally friendly media, e.g., water. The roles of the major components of ATRP--monomers, initiato...
Controlled radical polymerization has proven to be a viable route to obtain polymers with narrow polydispersities (PDI’s) and controlled molecular weights under simple reaction conditions. It also offers control over the chain‐ends of the synthesized polymer. Atom transfer radical polymerization (ATRP) is the most studied and utilized of these techniques. In this study ATRP has ...
A new method to prepare nanostructured hybrid hydrogels by incorporating well-defined poly(oligo (ethylene oxide) monomethyl ether methacrylate) (POEO(300)MA) nanogels of sizes 110-120 nm into a larger three-dimensional (3D) matrix was developed for drug delivery scaffolds for tissue engineering applications. Rhodamine B isothiocyanate-labeled dextran (RITC-Dx) or fluorescein isothiocyanate-lab...
styrene polymerization through frp and atrp methods was carried out at 110oc, while in-depth studies were performed by monte carlo simulation.the changes in monomer conversion, initiator concentration, average molecular weight, and polydispersity index were computed over the course of the polymerization. as the results indicate, compared to atrp, the frp reaches higher conversion in a similar r...
Compensatory mechanisms are often used to achieve stability by reducing variance, which can be accomplished via negative feedback during homeostatic regulation. In principle, compensation can also be implemented through feedforward mechanisms where a regulator acts to offset the anticipated output variation; however, few such neural mechanisms have been demonstrated. We provide evidence that an...
Poly(methyl methacrylate) grafted imogolite nanotubes prepared through surface-initiated ARGET ATRP.
Poly(methyl methacrylate) grafted imogolite clay nanotubes were fabricated via activators regenerated by electron transfer for atom transfer radical polymerization (ARGET ATRP) by designing a water-soluble amphiphilic ATRP initiator that can adsorb onto imogolite surface in an aqueous solution.
