In this work, the approach for separating paraffin wax is proposed by using Span 80 combined with switchable water N,N,N’,N’-tetramethyl-1,6-hexanediamine (TMHDA), where the emulsification of paraffin wax can be promoted and paraffin wax is also separated sustainably. Here, the Span 80-containing mixture system exhibits an enhanced emulsification ability and CO2-switchable behavior upon the addition of TMHDA. Then, the paraffin wax is effectively emulsified by this switchable system containing Span 80 and TMHDA. Based on the detection of water separation rate, rheol. behavior, and micrographs of emulsified paraffin wax, it is found that the emulsification of paraffin wax can be improved by increasing the paraffin wax content and Span 80 content, and the viscosity of the paraffin wax is reduced after emulsification by this switchable system, which ascribes to the dispersion of wax crystals. In addition, the paraffin wax is separated upon introducing CO2, and the TMHDA solution is recovered upon treating with N2 at 65°C after separating the paraffin wax. The sustainable separation of paraffin wax results from the aggregation of wax crystals because of the reduced obstruction of oil droplets for wax crystals caused by the high ionic strength and the reduced surface activity of this system upon introducing CO2. Herein, it is expected that this sustainable separation can be applied in deposited wax removal in pipelines of crude oil transport.

Zeolite MFI is a widely used catalyst and adsorbent that also holds promise as a thin-film membrane. The discovery of nanometer-thick two-dimensional (2D) MFI nanosheets has facilitated methods for thin-film zeolite fabrication that open new horizons for membrane science and engineering. However, the crystal structure of 2D-MFI nanosheets and their relationship to separation performance remain elusive. Using transmission electron microscopy, we find that one- to few-unit-cell-wide intergrowths of zeolite MEL exist within 2D-MFI. We identify the planar distribution of these 1D or near-1D-MEL domains, and show that a fraction of nanosheets have high (∼25% by volume) MEL content while the majority of nanosheets are MEL-free. Atomistic simulations show that commensurate knitting of 1D-MEL within 2D-MFI creates more rigid and highly selective pores compared to pristine MFI nanosheets, and permeation experiments show a separation factor of 60 using an industrially relevant (undiluted 1 bar xylene mixture) feed. Confined growth in graphite is shown to increase the MEL content in MFI nanosheets. Our observation of these intergrowths suggests strategies for the development of ultra-selective zeolite membranes.

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.

The synthesis of (-)-pyrrolam A starting from (R)-prolinol was described. The key step was the dehydrative alkylation of a conveniently protected (R)-prolinol I (R = CH2OH, R1 = CO2CMe3) with tri-Et methanetricarboxylate under the conditions of the Mitsunobu reaction to give tricarboxylate I [R = CH2C(CO2Et)3, R1 = CO2CMe3]. The tricarboxylate was converted to acid I [R = (CH2)2CO2H, R1 = H], which was cyclized to form (+)-dihydropyrrolam A (II). II was subsequently converted to (-)-pyrrolam A (III) via selenation with PhSeCl followed by oxidation with H2O2.

Three novel complexes, [Er(dmh)3(bipy)], [Er(dmh)3(bath)] and [Er(dmh)3(5NO2phen)], with 2,6-dimethyl-3,5-heptanedione (Hdmh) as the main sensitizer and either 2,2′-bipyridine (bipy), bathophenanthroline (bath) or 5-nitro-1,10-phenanthroline (5NO2phen) as synergistic ligands were synthesized. Upon excitation at the maximum absorption of the ligands, the complexes show the characteristic near-IR (NIR) luminescence of the Er3+ ions, due to efficient energy transfer from the ligands to the central Er3+ ion via the antenna effect. Single crystals were grown and their structures were determined showing different Er-N distances. The compound with shorter Er-N distances, [Er(dmh)3(5NO2phen)], is the best light harvester and the best for transferring the energy to the lanthanide among the three studied compounds Finally, the novel complexes were assessed for their application in sol-gel and polymer-based waveguides and optical amplifiers through their inclusion into ormosil and polymethylmethacrylate matrixes. The dispersion was successful in the bipy and 5NO2phen cases, with the properties of the hybrid materials mimicking those of the pure complexes.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 2,5-Diphenyloxazole( cas:92-71-7 ) is researched.Computed Properties of C15H11NO.Pfeifer, Viktor; Certiat, Marie; Bouzouita, Donia; Palazzolo, Alberto; Garcia-Argote, Sebastien; Marcon, Elodie; Buisson, David-Alexandre; Lesot, Philippe; Maron, Laurent; Chaudret, Bruno; Tricard, Simon; del Rosal, Iker; Poteau, Romuald; Feuillastre, Sophie; Pieters, Gregory published the article 《Hydrogen Isotope Exchange Catalyzed by Ru Nanocatalysts: Labelling of Complex Molecules Containing N-Heterocycles and Reaction Mechanism Insights》 about this compound( cas:92-71-7 ) in Chemistry – A European Journal. Keywords: heterocycle deuterium ruthenium deuteration catalyst; deuterated heterocycle preparation; tritium heterocycle ruthenium tritiation catalyst; tritiated heterocycle preparation; C−H activation; deuterium; hydrogen isotopic exchange; nanocatalysis; tritium. Let’s learn more about this compound (cas:92-71-7).

Ruthenium nanocatalysis can provide effective deuteration and tritiation of oxazole, imidazole, triazole and carbazole substructures in complex mols. using D2 or T2 gas as isotopic sources. Depending on the substructure considered, this approach does not only represent a significant step forward in practice, with notably higher isotope uptakes, a broader substrate scope and a higher solvent applicability compared to existing procedures, but also the unique way to label important heterocycles using hydrogen isotope exchange. In terms of applications, the high incorporation of deuterium atoms, allows the synthesis of internal standards for LC-MS quantification. Moreover, the efficacy of the catalyst permits, even under subatmospheric pressure of T2 gas, the preparation of complex radiolabeled drugs owning high molar activities. From a fundamental point of view, a detailed DFT-based mechanistic study identifying undisclosed key intermediates, allowed a deeper understanding of C-H (and N-H) activation processes occurring at the surface of metallic nanoclusters.
