Author is Hotton, Claire; Sirieix-Plenet, Juliette; Ducouret, Guylaine; Bizien, Thomas; Chenneviere, Alexis; Porcar, Lionel; Michot, Laurent; Malikova, Natalie.

We investigate the organization of clay nanoplatelets within a hydrogel based on modified ionenes, cationic polyelectrolytes forming phys. crosslinked hydrogels induced by hydrogen bonding and π-π stacking. Combination of small angle X-ray and neutron scattering (SAXS, SANS) reveals the structure of the polyelectrolyte network as well as the organization of the clay additives. The clay-free hydrogel network features a characteristic mesh-size between 20 and 30 nm, depending on the polyelectrolyte concentration Clay nanoplatelets inside the hydrogel organize in a regular face-to-face stacking manner, with a large repeat distance, following rather closely the hydrogel mesh-size. The presence of the nanoplatelets does not modify the hydrogel mesh size. Further, the clay-compensating counterions (Na+, Ca2+ or La3+) and the clay type (montmorillonite, beidellite) both have a significant influence on nanoplatelet organization. The degree of nanoplatelet ordering in the hydrogel is very sensitive to the neg. charge location on the clay platelet (different for each clay type). Increased nanoplatelet ordering leads to an improvement of the elastic properties of the hydrogel. On the contrary, the presence of dense clay aggregates (tactoids), induced by multi-valent clay counterions, destroys the hydrogel network as seen by the reduction of the elastic modulus of the hydrogel.

COA of Formula: C10H24N2. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: N1,N1,N6,N6-Tetramethylhexane-1,6-diamine, is researched, Molecular C10H24N2, CAS is 111-18-2, about Synthesis and antifungal activities of hydrophilic cationic polymers against Rhizoctonia solani. Author is Zhong, Weiqiang; Chang, Yaoyao; Lin, Yaling; Zhang, Anqiang.

A series of linear hydrophilic cationic polymers with different charge d. and mol. weights were synthesized by one-step polymerization process. The effect of the hydrophobicity and mol. weights on the antifungal activity against Rhizoctonia solani (R. solani) and Fusarium oxysporum f. sp. cubense race 4 (Foc4) was assessed. The biotoxicity of the cationic polymers were evaluated based on their median lethal concentration (LC50) for zebrafish and silkworm and median LD (LD50) for Kunming mice. The results indicated that the balance between antifungal activity and biotoxicity could be well tuned by controlling the hydrophobic-hydrophilic balance. The min. inhibitory concentration (MIC) of PEPB10 and PEPB25 against R. solani were 160μg/mL and 80μg/mL, resp. And the LD50 for Kunming mice of PEPB10 and PEPB25 were more than 5000 mg/kg, which mean that PEPB10 and PEPB25 with high hydrophilicity show low toxicity and better selectivity for R. solani. The cationic polymers can kill the R. solani by damaging their membranes and exchanging the Ca2+ or/and Mg2+ cations of their membranes or cell wall. These results help to understand the antifungal mechanism of low-toxic polymeric quaternary ammonium salts and highlight their potential application as highly selective fungicidal agents for controlling plant diseases.

Modern electrochem. energy conversion devices require more advanced proton conductors for their broad applications. Phosphonated polymers have been proposed as anhydrous proton conductors for fuel cells. However, the anhydride formation of phosphonic acid functional groups lowers proton conductivity and this prevents the use of phosphonated polymers in fuel cell applications. Here, we report a poly(2,3,5,6-tetrafluorostyrene-4-phosphonic acid) that does not undergo anhydride formation and thus maintains protonic conductivity above 200°C. We use the phosphonated polymer in fuel cell electrodes with an ion-pair coordinated membrane in a membrane electrode assembly. This synergistically integrated fuel cell reached peak power densities of 1,130 mW cm-2 at 160°C and 1,740 mW cm-2 at 240°C under H2/O2 conditions, substantially outperforming polybenzimidazole- and metal phosphate-based fuel cells. Our result indicates a pathway towards using phosphonated polymers in high-performance fuel cells under hot and dry operating conditions.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: N1,N1,N6,N6-Tetramethylhexane-1,6-diamine( cas:111-18-2 ) is researched.Application In Synthesis of N1,N1,N6,N6-Tetramethylhexane-1,6-diamine.Ma, Lingling; Qaisrani, Naeem Akhtar; Hussain, Manzoor; Li, Lv; Jia, Yabin; Ma, Siyu; Zhou, Ruiting; Bai, Lei; He, Gaohong; Zhang, Fengxiang published the article 《Cyclodextrin modified, multication cross-linked high performance anion exchange membranes for fuel cell application》 about this compound( cas:111-18-2 ) in Journal of Membrane Science. Keywords: cyclodextrin modified salt anion exchange fuel cell membrane. Let’s learn more about this compound (cas:111-18-2).

The anion exchange membranes (AEMs) with high hydroxide ion conductivity and stability are in an urgent need for alk. membrane fuel cell applications. High ionic exchange capacity (IEC) is necessary to improve conductivity but detrimental to stability. In this work, a series of novel AEMs modified with bulky rigid β-cyclodextrin (CD) and long flexible multiple quaternary ammonium (MQ) are designed and prepared The resulting AEM with a relatively low IEC of 1.50 mmol g-1 shows a good hydroxide ion conductivity of 112.4 mS cm-1 at 80 oC, whereas its counterpart without CD modification exhibits 83.0 mS cm-1 despite a similar IEC (1.60 mmol g-1); this is because the large CD units can impart high free volume to the membrane, reducing the ion transport resistance, and meanwhile, the hydrophilicity of CD′s external surface may promote formation of ion transport channels across the long flexible MQ cross-links. The CD modified AEM also imparts the membrane a better alkali- and swelling resistance as well as a higher tensile strength, without sacrificing its hydroxide ion conduction properties, than the un-modified membrane. The H2-O2 fuel cell yields a high peak power d. of 288 mW cm-2 at 60 oC. Our work implies that the CD enabled free volume strategy is effective to balance conductivity and stability, which may pave the way to fabrication of AEMs with further improved performance.

Diffuse intrinsic pontine glioma (DIPG) is associated with transcriptional dysregulation driven by H3K27 mutation. The super elongation complex (SEC) is required for transcriptional elongation through release of RNA polymerase II (Pol II). Inhibition of transcription elongation by SEC disruption can be an effective therapeutic strategy of H3K27M-mutant DIPG. Here, we tested the effect of pharmacol. disruption of the SEC in H3K27M-mutant DIPG to advance understanding of the mol. mechanism and as a new therapeutic strategy for DIPG. Short hairpin RNAs (shRNAs) were used to suppress the expression of AF4/FMR2 4 (AFF4), a central SEC component, in H3K27M-mutant DIPG cells. A peptidomimetic lead compound KL-1 was used to disrupt a functional component of SEC. Cell viability assay, colony formation assay, and apoptosis assay were utilized to analyze the effects of KL-1 treatment. RNA- and ChIP-sequencing were used to determine the effects of KL-1 on gene expression and chromatin occupancy. We treated mice bearing H3K27M-mutant DIPG patient-derived xenografts (PDXs) with KL-1. Intracranial tumor growth was monitored by bioluminescence image and therapeutic response was evaluated by animal survival. Depletion of AFF4 significantly reduced the cell growth of H3K27M-mutant DIPG. KL-1 increased genome-wide Pol II occupancy and suppressed transcription involving multiple cellular processes that promote cell proliferation and differentiation of DIPG. KL-1 treatment suppressed DIPG cell growth, increased apoptosis, and prolonged animal survival with H3K27M-mutant DIPG PDXs. SEC disruption by KL-1 increased therapeutic benefit in vitro and in vivo, supporting a potential therapeutic activity of KL-1 in H3K27M-mutant DIPG.

High ionic conductivity membranes can be used to minimize ohmic losses in electrochem. devices such as fuel cells, flow batteries, and electrolyzers. Very high hydroxide conductivity was achieved through the synthesis of a norbornene-based tetrablock copolymer with an ion-exchange capacity of 3.88 meq/g. The membranes were cast with a thin polymer reinforcement layer and lightly cross-linked with N,N,N’,N’-tetramethyl-1,6-hexanediamine. The norbornene polymer had a hydroxide conductivity of 212 mS/cm at 80°. Light crosslinking helped to control the H2O uptake and provide mech. stability while balancing the bound (i.e. waters of hydration) vs. free H2O in the films. The films showed excellent chem. stability with <1.5% conductivity loss after soaking in 1 M NaOH for 1000 h at 80°. The aged films were analyzed by FTIR before and after aging to confirm their chem. stability. A H2/O2 alk. polymer electrolyte fuel cell was fabricated and was able to achieve a peak power d. of 3.5 W/cm2 with a maximum c.d. of 9.7 A/cm2 at 0.15 V at 80°. The exceptionally high current and power densities were achieved by balancing and optimizing H2O removal and transport from the H neg. electrode to the O pos. electrode. High H2O transport and thinness are critical aspects of the membrane in extending the power and c.d. of the cells to new record values.
