Recently, a bifunctional oxide–zeolite (OX-ZEO) catalyst was widely studied experimentally, which can selectively convert syngas to light olefins. The performance of OX-ZEO is exceptional, while the mechanism controversial. In this work, we have first developed an algorithm based on graph theory establish complete reaction network for conversion methanol, ketene, and methane. Combined with density functional (DFT) calculations, activity selectivity over zinc oxide (ZnO) are systematically by...
Abstract Carbohydrates are essential moieties of many bioactive molecules in nature. However, efforts to elucidate their modes action often impeded by limitations synthetic access well‐defined oligosaccharides. Most the current methods rely on design specialized coupling partners control selectivity during formation glycosidic bonds. Reported herein is use a commercially available phenanthroline catalyze stereoretentive glycosylation with glycosyl bromides. The method provides efficient...
MOF-derived Ni@NC is prepared and used as highly selective catalyst for one-pot hydrogenation reductive amination.
Stereoselective formation of the 1,2-cis furanosidic linkage, a motif many biologically relevant oligosaccharides and polysaccharides, remains an important synthetic challenge. We herein report new stereoselective furanosylation method promoted by phenanthroline catalysts under mild operationally simple conditions. NMR experiments density functional theory calculations support associative mechanism in which rate-determining step occurs from inverted displacement faster-reacting...
Social skills are essential for fostering healthy relationships and promoting positive social interactions. Supporting students’ development of these has become increasingly important in educational contexts is emphasized within many countries’ national core curricula. However, teachers often lack pedagogical methods nurturing such skills. This study addresses this gap by investigating how the “Curious About Others” play based on solution-focused playful approaches can support learning In...
ConspectusThe National Research Council's report in 2012 recognized glycosidic bond forming (glycosylation) reactions as critical due to the central importance of carbohydrates glycosciences. This emphasized need for development reproducible and broadly applicable glycosylation technologies facilitate stereoselective synthesis biomedically relevant glycan libraries tool research applications by nonspecialists. In response this with NIH Common Fund support, publications new catalytic...
Upgrading ethanol to long-chain alcohols (LAS, C6+OH) offers an attractive and sustainable approach carbon neutrality. Yet it remains a grand challenge achieve efficient chain propagation, particularly with noble metal-free catalysts in aqueous phase, toward LAS production. Here we report unconventional but effective strategy for designing highly upgrading LAS, which Ni catalytic sites are controllably exposed on surface through sulfur modification. The optimal catalyst exhibits the...
Abstract Motivation Multiplexed protein imaging methods use a chosen set of markers and provide valuable information about complex tissue structure cellular heterogeneity. However, the number that can be measured in same sample is inherently limited. Results In this paper, we present an efficient method to choose minimal predictive subset for first time allows prediction full images much larger markers. We demonstrate our approach also outperforms previous predicting cell-level composition....
The design and fabrication of noble-free metal electrocatalysts for efficient hydrogen production with long-term stability are great significance, but very challenging. Herein, the first time, we report an iron phosphide/molybdenum phosphide hybrid covered by nitrogen/phosphorus dual-doped carbon (FeP/MoP@NPC) using polyoxometalate-based metal-organic frameworksas templates a facile two-step approach. As expected, composite shows highly electrocatalytic performance toward evolution reaction...
Rotational spectroscopy represents an invaluable tool for several applications: from the identification of new molecules in interstellar objects to characterization van der Waals complexes, but also determination very accurate molecular structures and conformational analyses. In this work, we used high-resolution rotational spectroscopic techniques combination with high-level quantum-chemical calculations address all these aspects two isomers cyanofuran, namely 2-furonitrile 3-furonitrile....
A photochemical approach toward RCOCF2-substituted pyrrolo[1,2-a]indolediones was developed by the radical cascade difluoroalkylation/cyclization reaction of unactivated 1-acryloyl-2-cyanoindoles with ethyl iododifluoroacetate or iododifluoramides under visible-light irradiation. This transition-metal- and photosensitizer-free protocol afforded diverse difluoroalkylated in moderate to good yields mild conditions. Most appealingly, can proceed smoothly sunlight irradiation, which opens a new...
A stoichiometric imbalance-promoted step growth polymerization method was developed based on self-accelerating 1,3-dipolar cycloaddition click reactions of Sondheimer diyne and varied 1,3-dipoles, such as diazo, sydnone, nitrone groups.
Novel zinc-palladium-porphyrin bimetal metal-organic framework (MOF) nanosheets were directly synthesized by coordination chelation between Zn(II) and Pd(II) tetra(4-carboxyphenyl)porphin (TCPP(Pd)) using a solvothermal method. Furthermore, serial of carbon supported Pd-Zn intermetallics (Pd-Zn-ins/CNS) with different Pd: Zn atomic ratios obtained one-step carbonization under temperature the prepared Zn-TCPP(Pd) MOF as precursor. In process, Pd-Zn-ins went through transformation from PdZn...
The rotational spectra of maleic anhydride-(H2O)1-3 have been investigated for the first time by using pulsed jet Fourier transform microwave spectroscopy with complementary computational analyses. experimental evidence points out that water tends to self-aggregate hydrogen bonds and form homodromic cycles. Differences in bond lengths charge distribution between two carbonyl sites observed upon stepwise hydrations, which might further introduce a selectivity on nucleophilic attack...
Heparanase cleaves polymeric heparan sulfate (HS) molecules into smaller oligosaccharides, allowing for release of angiogenic growth factors promoting tumor development and autoreactive immune cells to reach the insulin-producing β cells. Interaction heparanase with HS chains is regulated by specific substrate sulfation sequences. We have synthesized 11 trisaccharides that are highly tunable in structure pattern, us determine how recognizes selects a favorable cleavage site. Our study shows...
