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.

Methylenimine and cyanomethanimine synthesis from ion irradiation of N-2-CH4 ice: Implication on the formation of prebiotic molecules in outer solar system bodies

The synthesis of methylenimine and cyanomethanimine from ion irradiation of N-2-CH4 ice was studied, in an attempt to simulate the role of medium mass cosmic rays and energetic solar particles in the processing of nitrogen-rich ices on cold astrophysical environments, such as those in the outer region of the solar system (e.g. Pluto, Charon, Triton, Makemake and Titan). The N-2-CH4 (90:10) ice mixture was irradiated at 9 K by 38.4 MeV Ca-40(9+) (0.96 MeV/u) at the GANIL facility (Caen/Fance). The evolution of the samples was monitored using insitu Fourier transform infrared spectroscopy (FTIR). The results indicate the formation of CH2NH and CH2NCN, which are considered species of interest in prebiotic chemistry. Other species produced by radiolysis were HCN, HNC, hydrocarbons and nitriles. Direct comparison of the laboratory spectrum from the mixture of reaction products provides an efficient way to focus on the identification of chemical synthesis routes for the production of molecules important in the development of life that are consistent with the chemical inventory and physical conditions on frozen moons and cold objects in the outer solar system.

The requirement for cobalt in vitamin B-12: A paradigm for protein metalation

Vitamin B-12, cobalamin, is a cobalt-containing ring-contracted modified tetrapyrrole that represents one of the most complex small molecules made by nature. In prokaryotes it is utilised as a cofactor, coenzyme, light sensor and gene regulator yet has a restricted role in assisting only two enzymes within specific eukaryotes including mammals. This deployment disparity is reflected in another unique attribute of vitamin B-12 in that its biosynthesis is limited to only certain prokaryotes, with synthesisers pivotal in establishing mutualistic microbial communities. The core component of cobalamin is the corrin macrocycle that acts as the main ligand for the cobalt. Within this review we investigate why cobalt is paired specifically with the corrin ring, how cobalt is inserted during the biosynthetic process, how cobalt is made available within the cell and explore the cellular control of cobalt and cobalamin levels. The partitioning of cobalt for cobalamin biosynthesis exemplifies how cells assist metalation.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 154026-95-6, you can contact me at any time and look forward to more communication.

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.

Synthetic Studies on Cyclocitrinol: Construction of the ABC Ring System Based on Epoxy-Nitrile Cyclization

The stereoselective synthesis of a model compound containing the ABC ring system of cyclocitrinol was accomplished. After connecting a C ring allyltitanium segment with an A ring bi-cyclo[4.1.0]heptanone segment, the seven-membered B ring moiety was constructed by an intramolecular cyclization reaction of an epoxy nitrile. The enone moiety was introduced through an oxidative decyanation reaction, and the bicyclo[4.4.1]undecane skeleton with the highly strained olefin moiety was formed through a ring-opening reaction of the bicyclo[4.1.0]heptane substructure.
