Dynamic Monte Carlo simulations of effects of nanoparticle on polymer crystallization in polymer solutions
The presence of different nanoparticles can result in different polymer crystallization behaviors. Dynamic Monte Carlo simulations were used to study the effects of filler dimension and size on polymer crystallization. One-dimensional nanoparticle has the strongest ability to induce polymer crystallization, and can induce the formation of crystals with uniform orientation. The system filled with t...

Concentration Fluctuations near Lower Critical Solution Temperature in Ternary Aqueous Solutions
The effects of osmolytes, such as trimethylamine N-oxide (TMAO), on the phase transition in an aqueous solution of polymer, protein or DNA are very complex and several phase transitions can occur. In order to explore such effects, we take a simple ternary system of poly(N,N-diethyl acrylamide) and a favorable solvent pair TMAO and water to monitor the reduction in the miscibility of the polymer ...

Arsenic transport in rice and biological solutions to reduce arsenic risk from rice
Rice (Oryza sativa L.) feeds ～3 billion people. Due to the wide occurrence of arsenic (As) pollution in paddy soils and its efficient plant uptake, As in rice grains presents health risks. Genetic manipulation may offer an effective approach to reduce As accumulation in rice grains. The genetics of As uptake and metabolism have been elucidated and target genes have been identified for genetic eng...

Synthesis of Poly(2-aminothiazole) for Selective Removal of Hg(II) in Aqueous Solutions
Conducting poly(2-aminothiazole) (PAT) was simply green synthesized by a chemical oxidation method using 2-aminothiazole as the monomer and copper chloride as the oxidant in aqueous solution. The effects of reaction time and oxidant/monomer molar ratio on the polymerization yield were investigated. The PATs were characterized by FT-IR, 1H NMR, UV–vis, gel permeation chromatograms (GPC), and scann...

Phase Transition and Rheological Behaviors of Concentrated Cellulose/Ionic Liquid Solutions
The phase transition and rheological behaviors of concentrated solutions of microcrystalline cellulose (MCC) in an ionic liquid of 1-allyl-3-methylimidazolium chloride (AMIMCl) have been investigated. Polarized optical microscopy (POM) measurements indicate that the two critical cellulose concentrations for the appearance of biphase and fully anisotropic phase for MCC/AMIMCl solutions are 9 and 16...

Stability of Hydrogen-bonded Hydroxypropylcellulose /Poly(acrylic acid) Microcapsules in Aqueous Solutions
Hydroxypropylcellulose (HPC), a cellulose derivative, and poly(acrylic acid) (PAA) were assembled onto colloidal SiO2 particles in acidic solutions in a layer-by-layer manner, using hydrogen bonding as the driving force. Monodisperse hollow microcapsules were prepared by the removal of the sacrificial template. Long-term stability of the hydrogen-bonded capsules under various conditions was ...

Induced Circular Dichroism of Anionic Porphyrin TPPS Aggregates in DNA Solutions
Induced circular dichroism (CD) of achiral anionic tetrakis (4-sulfonatophenyl) porphine (TPPS) in polyanionic DNA solutions was investigated. Induced CD signals of the anionic TPPS aggregates in both cholesteric liquid crystal DNA solutions and isotropic DNA solutions are all observed within an appropriate pH range. When the pH value is less than 5, the induced CD signals of TPPS are split i...

75. A Conformation study of Polyelectrolyte-dendritic Surfactant Complexes in Dilute Solutions
Three dendronized polymers from generation one to generation three have been prepared by complexing negatively charged Frechet-type dendrons with a polyanion, poly(diallydimethylammonium chloride) (PDADMAC). The grafting degree has been confirmed mainly by elemental analysis. In dilute solutions of tetrahydrofuran, static light scattering studies indicate that the first generation complex has...

69. Salt-Induced Aggregation of Polyelectrolyte-Amphiphilic Dendron Complexes in THF Solutions
Complexes were prepared by complexing amphiphilic dendrons (first, second, and third generations) with an oppositely charged polyelectrolyte through ionic interaction. Their chemical structure can be confirmed by nuclear magnetic resonance spectroscopy (1H NMR), Fourier transform infrared spectroscopy (FT-IR), and elemental analysis (EA). All of the complexes were investigated with respect t...
