A seeded growth method for the fabrication of high-permeance, high-separation-factor zeolite (siliceous ZSM-5, [Si96O192]-MFI) membranes is reported. The consists growing crystals an oriented seed layer to a well-intergrown film by avoiding events that lead loss preferred orientation, such as twin overgrowths and random nucleation. Organic polycations are used crystal shape modifiers enhance relative rates along desirable out-of-plane direction. polycrystalline films thin (approximately 1...
Electron diffraction data are used to obtain the structure solution of a large-pore, high-silica zeolite, SSZ-48 that contains an occluded organic directing agent. The is determined by electron refinement and confirmed high-resolution transmission microscopy Rietveld powder synchrotron X-ray data. found contain one-dimensional pore system circumscribed 12 tetrahedral atoms (12 MR). most complex three-dimensional material be solved at atomic resolution using methods illustrates power for...
Reactions within crystals: Homochiral oligo(phenylalanine)s (see MALDI-TOF mass spectrum) were obtained from a racemic monomer by utilizing “zipperlike” mechanism in the solid state packing diagram). By generating such species crystalline architectures, formation of oligopeptides up to 17 units length is plausible.
The cytotoxic response, cellular uptake, and metabolomic profile of HeLa HaCaT cell lines treated with cobalt ferrite nanoparticles (CoFe2O4 NPs) were investigated in this study. Cell viability assays showed low cytotoxicity caused by the uptake at 2 mg/mL. However, metabolomics revealed that these impacted metabolism even when tested a concentration presented according to assay. two shared stress-related metabolic changes such as increase alanine creatine levels. A reduced level fumarate...
Abstract The formation of diastereoisomeric libraries oligopeptides through the heterogeneous polymerization racemic crystals phenylalanine N ‐carboxyanhydride (PheNCA) is reported. compositions formed on ( R , S ) incorporating deuterium‐tagged enantiomer were determined by MALDI‐TOF mass spectrometry. mixtures longer than pentamers are represented primarily diastereoisomers homochiral sequence and with peptides containing only one heterochiral repeating unit. A mechanism comprising...
Chitosan–zeolite composite as a low-cost and efficient material in the removal of caesium synthetic liquid organic radioactive waste solutions.
As part of our program on the search possible prebiotic routes for formation oligopeptides homochiral sequence (isotactic) from racemic precursors in aqueous environment, we report polymerization crystals phenylalanine N-carboxyanhydrides, enantioselectively tagged with five deuterium atoms, suspended water containing various amine initiators. Racemic mixtures isotactic oligopeptides, comprising up to 25 repeat units same handedness, as dominant component each length, were observed a...
Oligopeptide aus dem Kristall: Homochirale Phenylalanin-Oligomere entstehen im Festkörper des racemischen Monomers nach einem „Reißverschluss“-Mechanismus (siehe Bild). In Kristallen sollte auf diese Weise die Synthese von Oligopeptiden mit bis zu 17 Aminosäureeinheiten möglich sein.
Abstract Biodegradable polymeric microspheres can be used to deliver drugs through controlled rate and targeted processes. The drug is released from the particles by leaching or degradation of matrix. Crystallinity play a very important role in matrixes; it affect drug‐release rate, especially chemoembolization. Most commercial embolic agents have low degree crystallinity, correlation between drug‐delivery crystallinity not fully understood. This study presents appropriated synthesis...
Abstract The results of the histopathological analyses after implantation highly crystalline PVA microspheres in subcutaneous tissues Wistar rats are here reported. Three different groups microparticles were systematically studied: crystalline, amorphous, and commercial ones. In addition to these experiments, complementary architectural complexity performed using fractal dimension (FD), Shannon's entropy (SE) concepts. induced inflammatory reactions similar ones observed for ones, while...
Abstract An epoxy-functionalized beta type nanozeolite (BEA)/graphene oxide nanocomposite modified glassy carbon electrode (GCE/BEA/APTMS/GA/GO/NF) has been created for the differential pulse voltammetric determination of bisphenol E (BPE). The presented an enhanced current response in comparison with bare GCE. A linear dependence anodic peak ( I p ) and scan rate (ν) was observed, which showed that electrochemical process adsorption-controlled. Differential voltammetry (DPV) employed...
