Hirano, Tomohiro published the artcileSyndiotactic-specific radical polymerization of N-isopropylacrylamide in toluene at low temperatures in the presence of silyl alcohols, Application In Synthesis of 17877-23-5, the publication is Polymer International (2012), 61(6), 966-970, database is CAplus.

The radical polymerization of N-isopropylacrylamide was carried out in toluene at low temperatures in the presence of silyl alcs., such as triethylsilanol. Poly(N-isopropylacrylamide) with a racemo dyad content of 75% was obtained at – 80° with a 4:1 triethylsilanol to monomer ratio loading. NMR anal. suggests that the mechanism for syndiotactic induction, in the presence of silyl alcs., may be similar to that observed with alkyl alcs. In this case, a 1:2 complex formation, via hydrogen bonding interactions, leads to the induction of syndiotactic specificity. Copyright © 2012 Society of Chem. Industry.

Tanioka, Masaru published the artcileStepwise structural and fluorescent colour conversion in rhodamine analogues based on light and acid stimulations, Category: alcohols-buliding-blocks, the publication is Journal of Materials Chemistry C: Materials for Optical and Electronic Devices (2020), 8(2), 543-549, database is CAplus.

The research and development of multi-stimuli, multi-responsive mols. have attracted considerable attention in chem., biol., and material science. Herein, the authors propose a multi-stimuli-responsive multi-fluorescence system in a single mol. This system is based on the isomerization that involves ring-opening/closing reactions of spirolactones of rhodamine analogs (ABPXs), developed by the authors’ group, which can be independently controlled by light and chem. stimuli. UV light irradiation opens one of the spirolactones to give thermally stable colored isomer (Z) in solution Detailed synthetic and theor. studies reveal that the ring-opening reaction of ABPXs proceeds via the formation of a photo-induced charge separated state, followed by the recombination of the biradicals. Furthermore, the authors explore the structure-kinetic relations and demonstrate that the introduction of electron-donating substituents into the xanthene ring can tune the lifetime of the photo-generated isomer. Chem. stimulation by an acid further promotes the ring-opening reaction to give a red shifted isomer (D). These light and chem. input signals can be converted into output signals of distinct color and fluorescence. The multi-stimuli-responsive multi-color fluorescence could be distinctively expressed through the combinatorial logic gate.

Mori, Jiro F. published the artcileMultispecies diesel fuel biodegradation and niche formation are ignited by pioneer hydrocarbon-utilizing proteobacteria in a soil bacterial consortium, Quality Control of 86-48-6, the publication is Applied and Environmental Microbiology (2021), 87(1), e02268, database is CAplus and MEDLINE.

A soil bacterial consortium that was grown on diesel fuel and consisted of more than 10 members from different genera was maintained through repetitive subculturing and was utilized as a practical model to investigate a bacterial community that was continuously exposed to petroleum hydrocarbons. Through metagenomics analyses, consortium member isolation, growth assays, and metabolite identification which supported the linkage of genomic data and functionality, two pioneering genera, Sphingobium and Pseudomonas, whose catabolic capabilities were differentiated, were found to be responsible for the creation of specialized ecol. niches that were apparently occupied by other bacterial members for survival within the consortium. Coexisting genera Achromobacter and Cupriavidus maintained their existence in the consortium through metabolic dependencies by utilizing hydrocarbon biotransformation products of pioneer metabolism, which was confirmed through growth tests and identification of biotransformation products of the isolated strains. Pioneering Sphingobium and Pseudomonas spp. utilized relatively water-insoluble hydrocarbon parent compounds and facilitated the development of a consortium community structure that resulted in the creation of niches in response to diesel fuel exposure which were created through the production of more-water-soluble biotransformation products available to cocolonizers. That these and other organisms were still present in the consortium after multiple transfers spanning 15 years provided evidence for these ecol. niches. Member survival through occupation of these niches led to robustness of each group within the multispecies bacterial community. Overall, these results contribute to our understanding of the complex ecol. relationships that may evolve during prokaryotic hydrocarbon pollutant biodegradation

Tran, Chieu D. published the artcileChiral separation of amino acids by capillary electrophoresis with octyl-β-thioglucopyranoside as chiral selector, Synthetic Route of 85618-21-9, the publication is Journal of Chromatography A (2002), 978(1-2), 221-230, database is CAplus and MEDLINE.

1-S-Octyl-β-D-thioglucopyranoside (OTG) was evaluated as a chiral selector for the separation of dansylamino acids by capillary electrophoresis. Enantiomeric separations of the amino acids can be accomplished by judiciously adjusting the pH of the solution and the concentration of OTG. Better separation can be achieved, however, when OTG was used, not as a sole chiral selector but rather together with sodium dodecyl sulfate (SDS) and cyclodextrin (CD). Not only can this OTG-SDS-CD system provide better separation than OTG alone but also it can sep. compounds which cannot be separated when only CD or CD and SDS were used. All amino acids were baseline separated with this OTG-SDS-CD system at optimal conditions.

Xu, Xiaotong published the artcileFormation pathway of disinfection by-products of lignin monomers in raw water during disinfection, Synthetic Route of 645-56-7, the publication is Science of the Total Environment (2022), 153706, database is CAplus and MEDLINE.

In this study, the dissolved organic matter (DOM) profiles of water samples from a water source in northeastern China were analyzed by high-resolution mass spectrometry (HRMS), and its changes after chlorination were investigated. The results showed that lignin substances accounted for a significant proportion in DOM and chlorinated products and were the main precursors of disinfection byproducts (DBPs). During disinfection, macromol. DOM was transformed into small mols., and lignin substances have the most obvious and complex changes in reaction. Two lignin monomers 4-propylphenol (4PP) and 4-propylguaiacol (4PG) were used as model compounds to study their reaction kinetics and degradation pathways during disinfection. The degradation of both lignin monomers conformed to pseudo-first-order reaction kinetics, and the reaction rate constant of 4PG was higher than that of 4PP. The effects of chlorine dosage, pH and temperature on the degradation reaction kinetics of two lignin monomers were investigated. The degradation rates of 4PP and 4PG increased with increasing chlorine dosage, pH and temperature The two monomers showed similar properties in the chlorination degradation process, and generated multiple intermediates, which were mainly transformed into small mols. by chlorine electrophilic substitution and nucleophilic substitution, and further generated DBPs.

Herein, a rhodium-catalyzed amination of phenols, which provided concise access to diverse anilines, with water as the sole byproduct was described. The arenophilic rhodium catalyst facilitated the inherently difficult keto-enol tautomerization of phenols by means of π-coordination, allowing for the subsequent dehydrative condensation with amines. The generality of this redox-neutral catalysis by carrying out reactions of a large array of phenols with various electronic properties and a wide variety of primary and secondary amines was demonstrated. Several examples of late-stage functionalization of structurally complex bioactive mols., including pharmaceuticals, further illustrated the potential broad utility of the method.

Choi, Ji-Ae published the artcileCycling performance of a lithium-ion polymer cell assembled by in-situ chemical cross-linking with fluorinated phosphorus-based cross-linking agent, Application of 2,2′-((Perfluoroethane-1,2-diyl)bis(oxy))bis(2,2-difluoroethanol), the publication is Journal of Power Sources (2010), 195(18), 6177-6181, database is CAplus.

Li-ion polymer cells composed of a C anode and a LiCoO₂ cathode are assembled with a gel polymer electrolyte cured by in-situ chem. crosslinking with novel crosslinking agents. The strong interfacial adhesion between the electrodes and the porous polyethylene membrane by the chem. crosslinking results in the stable capacity retention of the cell. A reduction in the ionic mobility in both the electrolyte and the electrodes adversely affects the high rate performance of the cell. These results imply that proper control of the crosslinking d. in the cell is imperative for achieving good capacity retention and high rate performance of the cell.

Wan, Hui published the artcileEffect of high 2-KLG concentration on expression of pivotal genes involved in 2-KLG synthesis in Gluconobacter oxydans WSH-003, Application In Synthesis of 526-98-7, the publication is Weishengwu Xuebao (2016), 56(10), 1656-1663, database is CAplus and MEDLINE.

To analyze the effect of high 2-keto-L-gulonic acid (2-KLG) on important dehydrogenase, cofactor and transport proteins involved in 2-KLG synthesis. First, the growth of Gluconobacter oxydans under high 2-KLG was observed The real-time PCR was used to detect the expression of key sorbitol dehydrogenase gene sldAB, pyrroloquinoline quinone (PQQ) biosynthesis gene cluster pqqABCDE, and five genes encoding hypothetic PQQ transport proteins. According to results of the growth of G. oxydans under different 2-KLG concentration, 40, 80 and 120 g/L 2-KLG were decided to stimulate strains. Real-time PCR showed that PQQ synthesis genes pqqABCDE were not affected by high 2-KLG, but sorbitol dehydrogenase genes sldAB and part of genes encoding PQQ transport proteins were down-regulated under high 2-KLG stress. The expression of sorbitol dehydrogenase genes was restrained by high 2-KLG, PQQ transport was probably inhibited, but PQQ synthesis was not affected.
