Design and characterisation of vitrimer-like elastomeric composites from HXNBR rubber

The present study aims at the incorporation of vitrimer-like properties into elastomeric composites as a promising approach towards the sustainable production of rubber-based materials. In particular, hydrogenated carboxylated nitrile butadiene rubber (HXNBR), as a technically relevant high-performance rubber, is covalently cross-linked with epoxy group-functionalised calcium silicate (Esilicate) across its pending carboxylic acid moieties. Reaction with the reactive functions attached on the filler surface results in the formation of b-hydroxyl ester linkages at the HXNBR-Esilicate interface, which undergo thermo-activated transesterifications in the presence of a suitable catalyst. Topology rearrangements in the composites are confirmed by stress relaxation measurements at elevated temperatures. Comparison with an unfilled reference network reveals that the extent of stress relaxation can be mostly maintained upon the addition of the reactive filler even at large quantities. The Esilicate serves as both cross-linker and reinforcing filler, leading to a significant enhancement of the mechanical properties.

EPR free induction decay coherence observed after a single pulse in saturation recovery experiments for samples with resolved multiline CW spectra

An electron paramagnetic resonance (EPR) spin-coherence signal has been observed following a single pulse for rapidly tumbling radicals with well-resolved nuclear hyperfine splitting in fluid solution when B, is large enough to excite multiple hyperfine lines. This signal, which has the shape of a spin echo, arises from constructive interference of overlapping free induction decays (FIDs) from the hyperfine lines. It has been observed for 2,6-di-t-butyl-1,4-benzosemiquinone, 2,5-di-t-butyl-1,4-benzosemiquinone, 2,3,5,6-tetramethoxy-1,4-benzosemiquinone, 2,4,6-tri-t-butylphenoxyl radical, and 3carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy. It occurs at a time after the pulse that is equal to the inverse of the nuclear hyperfine splitting, independent of EPR resonance frequency from 250 MHz to 9.1 GHz. As the length of the pulse is increased, separate coherence signals can be observed that correspond to the beginning and end of the pulse. This coherence is distinct from the single-pulse echo signals discussed in the literature. For 2,6-di-t-butyl-1,4-benzosemiquinone, which has two resolved couplings (1.24 and 0.052 G), FID oscillations with a period that corresponds to the larger hyperfine coupling are observed on the coherence signal that arises from the smaller hyperfine coupling. If phase cycling is not perfect, the coherence signal can interfere with measurements of T-1 by saturation recovery.

Application of 107-97-1, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 107-97-1.

Preparation of Amorphous Poly(aryl ether nitrile ketone) and Its Composites with Nano Hydroxyapatite for 3D Artificial Bone Printing

PEEK had been used to fabricate artificial bones by 3D printing widely, but it expressed unsatisfactory interlayer performance of 3D printing and weak compatibility with nano hydroxyapatite(nHA) due to the limits of molecular structures. Here an amorphous poly(aryl ether ketone) for 3D bone printing, PEK-CN, was designed and synthesized via nucleophilic substitution from 4,4′-difluorobenzophenone, phenolphthalein and 2,6-dichlorobenzonitrile, which possessed much stronger interlayer strength due to van der Waals force between polar groups(-CNs). Specifically, the stronger interlayer strength resulted in lower porosity(3% with 100% infill rate) and more comparable mechanical properties(the maximum tensile strength was similar to 110 MPa) to cortical bone. Importantly, PEK-CN had passed in vitro cytotoxicity testing and samples of human mandible and maxillary bones based on PEKCN were printed by fused deposition modeling(FDM) successfully. Moreover, PEK-CN/nHA composites were obtained to enhance bioactivity of resin, and PEK-CN without limits of crystal lattices expressed excellent compatibility with nano hydroxyapatite. Our work provided a high performance resin for 3D bone printing, which would bring better solutions for artificial bone materials.

Flow Cytometric Analysis of the Influence of Myosmine on the Cell Cycle

Myosmine (3-(1-pyrrolin-2-yl)pyridine) is an alkaloid found in tobacco as well as various staple foods, fruits and vegetables. Myosmine has recently been suspected to be a tobacco-independent carcinogenic source. Using cell flow cytometry, we have examined the influence of myosmine on the cell cycle of murine erythroleukemia (MEL) cells in vitro and have compared this with its effects on murine bone marrow cells in vivo. Myosmine at low concentrations inhibited cell proliferation dose dependently; while at concentrations close to 300 mu mol dm(-3) it acted in a cytostatic fashion, that is, it increased the percentage of cells in the S and G2/M phases. At doses of 350-400 mu mol dm(-3) myosmine induced apoptosis and the hypoploid fraction. In vivo intraperitoneal injection of mice with 100 mg/kg of myosmine resulted in a statistically significant increase in the percentage of cells in S phase; i.e. from 13.75 to 18.22%. The percentage of bone marrow cells in the G2/M phase increased from 6.79 to 8.93 % in treated mice compared to controls. All of these results are in agreement with the hypothesis that myosmine possesses genotoxic potential. (doi: 10.5562/cca1767)

Functional rearrangement of polychlorinated pyrrolidin-2-ones to 5-imino-lactams promoted by n-propylamine

The reaction of 4-methyl-pyrrolidin-2-ones, chlorinated at the C(3) and C(6) positions, with n-propylamine constitutes a new method for the preparation of 5-propylimino-pyrrolidin-2-ones or 3-pyrrolin-2-ones in generally good yields. The transformation involves a series of eliminations, substitutions and double bond shifts. This constitutes a remarkable example of a functional rearrangement. (C) 2004 Elsevier Ltd.

Clean and molecularly programmable protocol for preparation of bis-heterobiarylic systems via a domino pseudocyclic reaction as a valuable alternative for TM-catalyzed cross-couplings

The domino sequence of pseudocyclic reactions involving 4-methoxybenzonitrile N-oxide and trans-2-phenyl-1-cyano-1-nitroethene proceeding in mild (r.t.; atm. pressure) non-catalytic (without participation of palladium or other transition metals (TM)) conditions yielded a bis-heterobiarylic molecular system containing an oxadiazole moiety with an almost 40% yield. The presented methodology represents therefore an evident contrast to the existing methods of preparation of bis-heterobiarylic systems, which require the presence of TMs. This reaction should be considered stereochemically clean and contains a stage of cycloaddition to the C=N bond. It should be underlined that this is the first case of non-catalyzed [3 + 2] cycloaddition involving the nitrile C=N bond. Our comprehensive study shows that the described protocol can be applied as a general methodology for preparation of a wide group of bis-heterobiarylic molecules. The self-adjusted cascade of transformations, which is unique and valuable from the practical point of view, leads to formation of a single isomeric product (from many possible) as a consequence of three pseudocyclic tandem reactions performed in agreement with the fundamental principles of green chemistry and sustainable development with a maximal level of atom economy and good overall yields. A self-adjustment phenomenon observed in the studied smart technology leading to production of a material with special properties was explained by it deep quantum nature confirmed undoubtedly by the modern Molecular Electron Density Theory.

Methylene Blue as a Photosensitizer and Redox Agent: Synthesis of 5-Hydroxy-1H-pyrrol-2(5H)-ones from Furans

A highly efficient and general singlet-oxygen-initiated one-pot transformation of readily accessible furans into 5-hydroxy-1H-pyrrol-2(5H)-ones has been developed. The methodology was extended to the synthesis of other high-value ,-unsaturated -lactams. This useful set of transformations relies not only on the photosensitizing ability of methylene blue, but also on its redox properties: properties that have until now been virtually ignored in a synthetic context.
