Enhanced energy density of poly(arylene ether nitriles) composites filled with surface engineered BaTiO3 nanoparticles

The introduction of nano-sized BaTiO3 (BT) into polymer host matrices brings about promising dielectric and energy storage properties. However, pristine BT tends to aggregate and is difficult to be compatible with polymer matrices, thus requiring surface modification of BT nanoparticles. In this work, gamma-aminopropyl triethoxysilane (KH550) was grafted onto the surface of BT as a shell and amino-functionalized core-shell KH550@BT nanoparticles have been successfully prepared. Thereafter, poly(arylene ether nitrile) (PEN) has been chosen as polymer matrix due to its excellent thermal properties, and xKH550@BT/(1-x)PEN composite films were prepared by solution casting film formation method. The energy density of KH550@BTIPEN composites with 30 wt.% filler loading is 1.30 J cm(-3) (eta = 61.32 %) at 150 MV m(-1), more than 36.84 % increase when compared with pristine PEN polymer (0.95 J cm(-3) at 170 MV m(-1)). Temperature-dependent and frequency-dependent D-E loops confirmed that KH550@BTIPEN composites possess good temperature and frequency stability. (C) 2020 Elsevier B.V. All rights reserved.

Regulation of p42/p44 MAPK and p38 MAPK by the adenosine A(1) receptor in DDT1MF-2 cells

The mitogen-activated protein kinase (MAPK) family consists of the p42/p44 MAPKs and the stress-activated protein kinases, c-Jun N-terminal kinase (JNK) and p38 MAPK. We have previously reported that the human adenosine A(1) receptor stimulates p42/p44 MAPK in transfected Chinese hamster ovary cells. In this study, we have investigated whether the endogenous adenosine A(1) receptor in the smooth muscle cell line, DDT1MF-2 activates p42/p44 MAPK, JNK and p38 MAPK. The adenosine A(1) receptor agonist N-6-cyclopentyladenosine stimulated time and concentration-dependent increases in p42/p44 MAPK and p38 MAPK phosphorylation in DDT1MF-2 cells. No increases in JNK phosphorylation were observed following adenosine A(1) receptor activation. N-6-cyclopentyladenosine-mediated increases in p42/p44 MAPK and p38 MAPK phosphorylation were blocked by the selective adenosine A(1) receptor antagonist 1,3-dipropylcyclopentylxanthine and following pretreatment of cells with pertussis toxin. Furthermore, adenosine A(1) receptor-mediated increases in p42/p44 MAPK were sensitive to the MAPK kinase 1 inhibitor PD 98059 (2′-amino-3′-methoxyflavone), whereas p38 MAPK responses were blocked by the p38 MAPK inhibitor SE 203580 (4-(4-fluorophenyl)-2-(4-methylsulfinylphenyl)-5-(4-pyridyl)1H-imidazole). The broad range protein tyrosine kinase inhibitors genistein and tyrphostin A47 (alpha -cyano-(3,4-dihydroxy)thiocinnamide) did not block adenosine A(1) receptor stimulation of p42/p44 MAPK. For comparison, insulin-mediated increases in p42/p44 MAPK were blocked by genistein and tyrphostin A47. The Src tyrosine kinase inhibitor PP2 (4-amino-5-(4-chlorophenyl)-7-(t-butyl)pyrazolo[3,4-d]pyrimidine) and the epidermal growth factor receptor tyrosine kinase inhibitor AG1478 (4-(3-chloroanilino)-6,7-dimethoxyquinazoline) also had no effect on adenosine A(1) receptor stimulation of p42/p44 MAPK. Furthermore, the protein kinase C inhibitors Ro 31-8220 (3-{1-[3-(2-isothioureido)propyl]indol-3-yl}-4-(1-methylindol-3-yl)-3-pyrrolin-2,5-dione) chelerythrine and GF 109203X (2-[1-(3-dimethylaminopropyl)-1H-indol-3-yl]3-(1H-indol-3-yl)-maleimide) were without effect on adenosine A(1) receptor-induced p42/p44 MAPK phosphorylation. In contrast, wortmannin and LY 294002 (2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one), inhibitors of phosphatidylinositol 3-kinase, attenuated adenosine A(1) receptor stimulation of p42/p44 MAPK phosphorylation. In conclusion, the adenosine A(1) receptor stimulates p42/p44 MAPK through a pathway which appears to be independent of tyrosine kinase activation but involves phosphatidylinositol 3-kinase. Finally, adenosine A(1) receptor stimulation in DDT1MF-2 cells also activated p38 MAPK but not JNK via a pertussis toxin-sensitive pathway. (C) 2001 Elsevier Science B.V. All rights reserved.

A catalyst-free and recycle-reinforcing elastomer vitrimer with exchangeable links

Vitrimers, as intriguing polymers, possess exchangeable links in the crosslinking networks, endowing them with the abilities of recycling and reprocessing. However, most of vitrimers are generally fabricated via complex synthesis and polymerization processes. Toxic and unstable exogenous catalysts are inevitably applied to activate the exchange reaction to rearrange the crosslinking networks. These drawbacks limit the widespread applications of vitrimers. Moreover, most reported vitrimers could only partially maintain or severely deteriorate their mechanical properties after recycling. Herein, to solve the above-mentioned problems, for the first time, a catalyst-free and recycle-reinforcing elastomer vitrimer is revealed. By the reactive blending of commercially available epoxidized natural rubber and carboxylated nitrile rubber, the elastomer vitrimer associated with exchangeable beta-hydroxyl ester bonds was obtained. Strikingly, the vitrimer exhibits an exceptional recycle-reinforcing property. This work provides a feasible method to fabricate elastomer vitrimers, which promotes the recycling of crosslinking commercial available elastomers.

Influence of ultraviolet aging on the structure, mechanical and gas permeability properties of hydrogenated nitrile butadiene rubber

The effect of ultraviolet (UV) radiation on the structure and performance of hydrogenated nitrile butadiene rubber (HNBR) was studied in this paper. The HNBR was exposed to UV radiation for various durations (0, 7, 14, 21 and 28 days). The Fourier transform infrared spectroscopy (FTIR) results demonstrated that the surface molecular structures were oxidized to generate oxygenated species under UV radiation. The oxidative degree enhanced with the increase of aging time, resulting in thicker and denser cracks on the surface. The plausible aging mechanism of HNBR was suggested. The free volume of HNBR before and after UV aging was characterized by positron annihilation lifetime spectroscopy (PALS) and their cross-linking density, compression set, mechanical and gas permeability properties were also analyzed. In the first 14 days of UV irradiation, the dominant chain-scission reaction led to a decrease in cross-linking density of HNBR, resulting in the enhancement of free volume and thereby the increase of gas permeability. When the aging time was longer than 14 days, cross-linking reaction played a leading role and the free volume decreased, thus causing the reduction of gas permeability. As the aging time increased, the glass transition temperature (T-g), tensile strength and storage modulus of HNBR initially reduced and then increased, which was in agreement with the changing trend of cross-linking density.

Application of analytical pyrolysis to gain insights into proteins of condensed corn distillers solubles from selective milling technology

Present study evaluates the analytical pyrolysis to unravel the pyrolysate compounds (PyCs), protein & glycosylation indicators in a protein fraction (PF) from condensed corn distillers solubles (CCDS) of novel selective milling technology. Besides, quadratic and linear corre-lations using protein content (%) by Dumas method, toluene signature PyC, and elemental nitrogen (%) were developed. Pyrolysis was performed at temperature of 400 degrees C, where most of the PyCs released from proteins in a lignin-free PF instead of other constituents. The p cresol and methyl 9,12-octadecadienoate were found with the highest area% of 3.2 and 19.3 in PF and CCDS, respectively. Protein derived PyCs such as nitrogen heterocyclics, amines & amides and nitriles were examined 63.93%, 61.90% and 70% greater in PF than CCDS. Moreover, the indicators of protein were toluene, p-cresol, phenol, phenylacetonitrile, 4vinylphenol, whereas that of glycosylated protein were methyl mercaptan, furan derivatives, and hexahydro-3-(phenylmethyl) pyrrolo [1, 2 a] pyrazine-1,4-dione. The absence of diketopiperazines provided evidence of crosslinking and aggregation of protein. The values of the protein content obtained from the quadratic model and Dumas method were found to be statistically non-significant (p < 0.05) imply the model validity. The results would aid in bioconversion of CCDS to future value-added products. (C) 2020 Institution of Chemical Engineers. Published by Elsevier B.V. All rights reserved.

Synthetic Exploration of alpha-Diazo gamma-Butyrolactams

DIazo transfer reaction onto -butyrolactams (activated by -ethyloxalylation) gave rare -diazo -butyrolactams. Decomposition of the latter by Rh-2(OAc)(4) in the presence of alcohols and water gave products of O-H insertion of the respective metal-cabene species. Silver triflate (1 mol-%) was found to convert the -butyrolactams investigated into 1,5-dihydro-2H-pyrrol-2-ones which represent versatile building blocks. Particular instability was noted for -diazo -butyrolactams bearing alkyl or o-substituted aryl substituents on the nitrogen atom. These were found to dimerize in solution or upon storage at room temperature to give fully conjugated bis-hydrazones along with the loss of a nitrogen molecule.
