Polarizing effect in natural polymer cellulose

Effect of Polyanionic Cellulose Polymer Nanoparticles on Rheological Properties of Drilling Mud

Polyanionic cellulose polymer is used as an additive in drilling mud in order to decrease water loss and mudcake- thickness. In this study effect of bulk and nanosize polyanionic cellulose on water loss and mud-cakethickness in mud drilling is investigated. Polyanionic cellulose nanoparticles are made by using of ball milling. Size of nanoparticles is measured by Particle size analyzer. Polyani...

Running head: POLARIZING EFFECT OF AROUSAL 1 The Polarizing Effect of Arousal on Negotiation

This research examines the impact of physiological arousal on negotiation outcomes. Conventional wisdom and extant prescriptive literature suggest that arousal should be minimized given its negative effect on negotiations, while prior research on misattribution of arousal suggests that arousal might polarize outcomes, either negatively or positively. In two experiments, we manipulated arousal a...

Nanocoating of natural cellulose fibers with conjugated polymer: hierarchical polypyrrole composite materials.

Astonishingly uniform polypyrrole nanocoating on morphologically complex cellulosic substances was achieved without disrupting the hierarchical network structures of individual cellulose fibers by means of polymerization-induced adsorption.

Interfacial Studies of Cellulose Whisker Polymer Nanocomposites

The molecular deformation of cotton cellulose whisker/epoxy resin (CW/EP) and tunicate whisker/poly(vinyl) acetate (TW/PVAc) composites were investigated using Raman spectroscopy. A shift in the 1095 cm Raman peak position is recorded for samples deformed in both tension and compression, which corresponds to the molecular deformation of the cellulose chains within the whiskers. Cyclic molecular...
