Song, Shizhu published the artcileImidazolium ionic Liquid-Regulated Sub-5-nm Pt(1 1 1) with a stable configuration anchored on hollow carbon nanoshells for efficient oxygen reduction, Name: 1-Bromododecane, the publication is Journal of Colloid and Interface Science (2022), 606(Part_1), 177-191, database is CAplus and MEDLINE.

Here, N-doped hollow carbon sphere (NHCS)-supported (1 1 1)-plane-engineered sub-5-nm Pt (Pt-NHCS) catalysts regulated precisely by imidazolium ionic liquids were synthesized successfully and used to catalyze oxygen reduction The (1 1 1)-plane engineered Pt nanocrystals with a diameter of 4.5 ± 0.5 nm were homogeneously deposited on the 3-dimensional spherical nanoshells. The resulting Pt nanocrystals anchored on the carbon skeleton exhibit a stable configuration in both alk. and acid electrolytes with the help of imidazolium cations and pyrolysis. Among all as-prepared catalysts, the optimized Pt-NHCS shows remarkable long-term durability. Specifically, Pt-NHCS maintains 95.3% of the original c.d. after 10,000 potential cycles, while Pt/C benchmarks exhibit a retention of 78.5%. Accelerated durability test results indicate that Pt-NHCS exhibits a high efficiency of 96% in comparison with initial c.d., while a value of 86% for Pt/C. D. functional theory calculations demonstrate that reactive Pt(1 1 1) planes with well-defined Schottky defects and vacancies adsorb and activate oxygen mol. rapidly while desorbing the reaction intermediates.

Zhuang, Zhuoxin published the artcileMelt and nucleation reinforcement for stereocomplex crystallites in poly(L-lactide)/lignin-grafted-poly(D-lactide) blend, Recommanded Product: 1-Bromododecane, the publication is European Polymer Journal (2022), 111072, database is CAplus.

Lignin-grafted-poly(D-lactide) (LGPD) with two different poly(D-lactide) (PDLA) block lengths (1100 and 2000 Da), denoted as LGPD_L and LGPD_H resp., were synthesized by ring opening polymerization using dodecylated lignin as initiator. They were then blended with poly(L-lactide) (PLLA) to improve its crystallization, mech. properties and UV-absorbance properties. It was found that stereocomplex (SC) crystallites could be formed in both PLLA/LGPD blends, and the crystallization rate of PLLA/LGPD_H was faster than that of PLLA/LGPD_L because of the longer PDLA block length. Both in the non-isothermal and isothermal crystallization process, the crystallization of PLLA in the PLLA/LGPD_H blend was the fastest when the ratio of LGPD_H was 3%. SC crystallites in the PLLA/LGPD_H blends also showed broader melting ranges and higher final melting temperatures comparing to the blends of PLLA and 4-armed PDLA (4a-PDLA), whose number of PDLA arms and mol. weight was similar to LGPD_H. These results proved that the lignin structure grafted by the PDLA arms could affect the state of SC crystallites and their acceleration effect on the crystallization of PLLA in the blend. The degradation behavior showed that the degradation rate of the LGPD_H-5% blend in the final stage of degradation (about 24 h) was the slowest comparing to other blends. Besides, the PLLA/LGPD blends had better tensile strength and UV-absorbance properties than neat PLLA.

Cao, Xiang-Jian published the artcileControlling the Balance of Photoluminescence and Photothermal Effect in Cyanostilbene-Based Luminescent Liquid Crystals, Quality Control of 143-15-7, the publication is Chinese Journal of Chemistry (2022), 40(8), 902-910, database is CAplus.

Mol. motions of the luminescent liquid crystals (LLCs) show a significant effect on fluorescent emission and heat generation. In this article, a series of cyanostilbene-based LLCs (CSs: CS1-6, CS1-12, CS2-6 and CS2-12) are synthesized to investigate how the photoluminescence and photothermal effect balanced. Among these materials, the mesogens peripheried by single alkyl chains formed enantiotropic nematic (CS1-6) or smectic C (CS1-12) phase with different alkyl tail lengths. When the single aliphatic chain is replaced by mini-dendrons, room temperature (RT) monotropic hexagonal columnar phase (CS2-12) or mol. liquid (CS2-6) is formed. The results revealed that all these materials exhibited high efficiency emission with the highest quantum yield reaching 59.0%. The photoluminescence and photothermal effect can be effectively tuned by dispersing CSs into a com. available RT liquid crystal matrix 8CB, which output significantly improved photothermal conversion efficiency of 63.2%. Furthermore, the photothermal can rapidly trigger the Smectic A-Nematic-Isotropic sequence transitions of 8CB doped with CSs. This work paves a way of adjusting the balance of photoluminescence and photothermal properties of the LLC materials.

Fetin, P. A. published the artcileComb-like polyelectrolytes – new surfactants with controlled solubilization capacity, Safety of 1-Bromododecane, the publication is Journal of Molecular Liquids (2022), 119085, database is CAplus.

Cationic surface-active monomers with 11-acryloyloxyundecyl tail in quaternary ammonium group and the corresponding comb-like polyelectrolytes are investigated. The sources of quaternary ammonium were aliphatic amines (trimethylamine and triethylamine) or aromatic and aliphatic cyclic amines (N-methylpiperidine, N-methylmorpholine, pyridine, quinoline). The monomer to polymer transformation increases the solubilization capacity of surfactant in one order of magnitude. The comb-like polyelectrolytes are capable to effective solubilization of hydrophobic probe over the wide concentration range including extremely low concentrations of the polymer. There aren’t any precipitations of comb-like polyelectrolytes with temperature decrease unlike of many ionic low-mol. weight surfactants. Solubilization capacity of the hydrophobic probe by comb-like polyelectrolyte is slightly influenced by the mol. weight of the polymer and is determined by the nature of the ionic group of comb-like polyelectrolyte and counterion.

Kuznetsova, Darya A. published the artcileCationic Imidazolium Amphiphiles Bearing a Methoxyphenyl Fragment: Synthesis, Self-Assembly Behavior, and Antimicrobial Activity, Recommanded Product: 1-Bromododecane, the publication is Langmuir (2022), 38(16), 4921-4934, database is CAplus and MEDLINE.

Novel cationic amphiphiles of the 3-alkyl-1-(4-methoxyphenyl)-1H-imidazol-3-ium bromide series bearing methoxyphenyl fragments (MPI-n) have been synthesized. Their aggregation properties in aqueous solutions, solubilization capacity, and hemolytic and antimicrobial activities have been investigated by a number of physicochem. methods. Using tensiometry, conductometry, and fluorescence spectroscopy, it was shown that the MPI-n have lower CMCs than their nonfunctionalized counterparts. The unusual alkyl-chain-length-dependent morphol. of aggregates is testified for this homol. series. Amphiphiles with 12, 14, and 16 alkyl tails are characterized by the formation of micellar aggregates, while a surfactant with a decyl tail is characterized by the formation of larger aggregates with lower surface curvature. The MPI-10 aggregate morphol. was rationalized in terms of the packing parameter consideration and was supported by size measurements and the fluorescence probe techniques, which showed that vesicle-like aggregates in close-packing mode probably occur. MPI-n aggregates have exhibited a high solubilization capacity toward hydrophobic azo dye Orange OT. Importantly, amphiphiles studied showed (i) high bacteriostatic activity at the level of ciprofloxacin; (ii) high bactericidal action against all Gram-pos. bacteria, including methicillin-resistant strains; (iii) bactericidal properties against Gram-neg. bacteria; and (iv) low hemolytic activity.

Wojcieszak, Marta published the artcileSurface activity and phytotoxicity of morpholinium herbicidal ionic liquids, Safety of 1-Bromododecane, the publication is Journal of Molecular Liquids (2022), 119750, database is CAplus.

The use of efficient synthesis methods to obtain novel herbicidal ionic liquids (HILs) with biol. activity is extremely important because it can eliminate certain neg. environmental impacts. The authors of this work succeeded in the experiment, which resulted in the synthesis of 18 novel ionic liquids with high yields. Furthermore, a number of physicochem. and biol. properties have been investigated, including surface activity, thermal anal., and phytotoxicity. In addition, it was proven that morpholinium ionic liquids with phenoxyacid anions were more effective against cress than HILs previously studied in the literature. To the best of our knowledge, this is the first report of surface-active ionic liquids with herbicidal anions where leaf surfaces were used for anal. An important aspect of this work was to compare the wettability of the surfaces of wheat leaves and weeds. Moreover, it was shown that using paraffin as a reference surface was not sufficient to describe the wetting properties of HILs. The research reported here proved that morpholinium ionic liquids were effective in wetting weed surfaces while they do not adversely affect wheat leaf surfaces. Our results could be significant for meeting the environmental challenges and agricultural demands of the future.
