Abstract High-performance membranes exceeding the conventional permeability-selectivity upper bound are attractive for advanced gas separations. In context microporous polymers have gained increasing attention owing to their exceptional permeability, which, however, demonstrate a moderate selectivity unfavorable separating similarly sized mixtures. Here we report an approach designing polymeric molecular sieve via multi-covalent-crosslinking of blended bromomethyl polymer intrinsic...
To confront the energy consumption, high performance membrane materials are urgently needed. Carbon molecular sieve (CMS) membranes exhibit superior capability in separating gas mixtures efficiently. However, it remains a grand challenge to precisely tune pore size and distribution of CMS further improve their sieving properties. Herein, we report an approach finely modulating structure by using reactive Al(CH3)3 situ defluorinate polymer precursor form Al-Fx(CH3)3-x matrix, which is...
The epipolythiodioxopiperazines (ETPs) are fungal secondary metabolites proven to trigger both apoptotic and necrotic cell death of tumor cells. However, the underlying mechanism their regulatory role in macroautophagy interplay between autophagy apoptosis initiated by ETPs, remain unexplored. In current work, we found that 11'-deoxyverticillin A (C42), a member induces autophagosome formation, accumulation microtubule-associated protein 1 light chain 3-II (LC3-II ) degradation sequestosome...
A general and efficient phosphorous acid-catalyzed cyclocondensation of β-ketoesters with o-aminobenzamides via selective C-C bond cleavage leading to quinazolinones is developed. This reaction proceeds smoothly under metal- oxidant-free conditions, giving both 2-alkyl- 2-aryl-substituted in excellent yields. strategy can also be applied the synthesis other N-heterocycles, such as benzimidazoles benzothiazoles.
Abstract Tailoring the microporosity of intrinsically microporous polymers at atomic level is one biggest challenges in achieving high‐performance polymeric gas separation membranes. In this study, for first time, Al 2 O 3 layer deposition (ALD) technique was used to modify a typical polymer intrinsic (PIM‐1) level. PIM‐1 with six ALD cycles (PIM‐1‐Al ‐6) exhibited simultaneous high thermal, mechanical, pure‐ and mixed‐gas separation, anti‐aging properties. The /N , H /CH 4 performances were...
Certain polymers with very high free volume demonstrate a continuous network of interconnected void spaces due to the shape and rigidity its macromolecular composition; as such, it becomes an intrinsic property for these otherwise seen microporosity (PIM). Methylated (PIM-M), bromoalkylated PIM (PIM-BM-x), thermally self-cross-linked PIM-BM-x were designed prepared gas separation performance enhancements. The polymeric membranes demonstrated exceptional compared PIM-M surpassed 2008 Robeson...

Abstract The first copper‐catalyzed aerobic oxidative C(aryl)OH bond functionalization of catechols is reported. Under air, at room temperature, in the presence a copper catalyst, react with amines to produce corresponding benzoxazoles high yields. Mechanistic studies suggest that reaction proceeds via an intriguing competitive oxidation and synergetic catalysis between catechol amine. magnified image
A Gram-stain-positive strain designated MDB1-42T was isolated from ice collected Midui glacier in Tibet, PR China. Strain catalase-positive, oxidase-negative and grew optimally at 25-28 °C pH 7.0. Phylogenetic analysis based on 16S rRNA gene sequences revealed that represented a member of the genus Arthrobacter. The highest level sequence similarity (99.86 %) found with Arthrobacter agilis NBRC 15319T. Multilocus low 91.93 % between Average nucleotide identity digital DNA-DNA hybridization...
