Reduced graphene oxide grafted by the polymer of polybromopyrroles for nanocomposites with superior performance for supercapacitors

An integrated structure has been designed by grafting the polymer of polybromopyrroles (PPBP) onto reduced graphene oxide (RGO) to produce RGO/PPBP nanocomposites with superior electrochemical performance for supercapacitors. The RGO/PPBP nanocomposites are featured with a high nitrogen content (>9 at%), enhanced degree of graphitization, improved specific surface area, abundant micropores, and a tunable hierarchical structure on the basis of sample characterization by XRD, Raman, FT-IR, XPS, SEM, high-resolution TEM, BET, and scanning probe microscopy (SPM) techniques. The grafting of PPBP onto RGO not only suppresses agglomeration and restacking of RGO but also tailors the growth of PPBP on RGO, producing a developed hierarchical structure beneficial for mass/charge transfer. The synergistic effect between RGO and PPBP ensures superior electrochemical performance of RGO/PPBP. In a three-electrode mode, the typical RGO/PPBP electrode presents a galvanostatic capacitance (Cg) of 256 F g-1 at a current density of 10 A g-1, with a capacitance retention of 99.2% after 10000 cycles in 1 mol L-1 H2SO4. More significantly, the typical RGO/PPBP&3Verbar;RGO/PPBP supercapacitor cell exhibits a high Ccell value of 68 F g-1 at 5 A g-1, with a capacitance retention of 91.9% after 10000 cycles. Also, relatively high energy density values of 13.6, 9.4, and 6.7 W h kg-1 with the corresponding power density of 0.5, 2.5, and 10 kW kg-1 are achieved, enabling the tested cell to stay at the high level for carbon-based supercapacitors with an aqueous electrolyte.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Recommanded Product: 13950-21-5, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 13950-21-5, in my other articles.

ALKALOIDS OF Papaver argemone L. AND Papaver pavonium Fisch. et MEY. FROM THE Argemonorhoeades FEDDE SECTION

Papaver argemone L. and Papaver pavonium FISCH. et MEY. species of the Argemonorhoeades FEDDE (Papaveraceae) section were studied.A very low content of alkaloids was found in both species (less than 0.05percent).P. argemone contains corytuberine and its quaternary N-methyl derivative magnoflorine as the dominant bases.As minor constituents were isolated: protopine, isocorydine, scoulerine, and alkaloids PAR 1, PAR 2, PAR 3.Chromatographic analysis detected allocryptopine, cryptopine, coptisine and traces of rhoeadine, papaverrubines C, D and E, and more than 6 unidentified bases.P. pavonium gave N2-methyl-1,2,3,4-tetrahydro-beta-carboline as the dominant alkaloid, along with minor amounts of the tertiary bases protopine, allocryptopine, corydine, isocorydine and corytuberine.Of quaternary bases, coptisine, magnoflorine and an unidentified alkaloid PP 1 were isolated.The presence of many other, considerably labile bases has been proven in both species

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C11H9NO3, you can also check out more blogs about1081-17-0

Periodically functionalized and grafted copolymers via 1:2-sequence- regulated radical copolymerization of naturally occurring functional limonene and maleimide derivatives

Naturally occurring hydroxy-functionalized limonene analogues, i.e., monoterpene alcohols such as perillyl alcohol and carveol, were radically copolymerized with cyclohexylmaleimide (CyMI) in PhC(CF3) 2OH via 1:2-sequence-regulated propagation to obtain periodically functionalized bio-based copolymers possessing one hydroxyl group in every three-monomer unit. Alternatively, a combination of hydroxy-functionalized maleimide (N-2-hydroxyethylmaleimide: HEMI) and limonene resulted in another periodically functionalized copolymer possessing two hydroxyl groups for every three-monomer unit. These copolymerizations were fitted well by the penultimate model, where the hydroxyl functions did not have a significant effect on the selective propagation, as has been reported for a combination of nonfunctionalized limonene and CyMI. The periodic hydroxyl groups can be quantitatively converted into carbamate moieties by a polymer reaction with isocyanate to result in another series of 1:2 and 2:1 periodically functionalized copolymers. Periodically grafted copolymers possessing one or two graft chains repeating in three-monomer units were prepared by radical copolymerization of chlorine-functionalized limonene or maleimide derivatives, which were synthesized from hydroxy-functionalized monomers, followed by ruthenium-catalyzed living radical polymerization of methyl methacrylate initiated from periodically introduced C-Cl bonds in the backbone copolymers.

Fluorescent Labeling of Protein Using Blue-Emitting 8-Amino-BODIPY Derivatives

8-Amino-BODIPY (boron-dipyrromethane) dyes show bright blue fluorescence. Disclosed here are synthesis and characterization of the photophysical properties of a series of functionalized 8-Amino-BODIPY (BP1?4) for protein labeling. The compact structure and solvent-insensitive absorption property of the dye are desirable features for protein labeling. For the model protein, bovine serum albumin (BSA), the labeling proceeds under mild condition via amide bond formation or thiol-ene conjugation with maintaining the bright blue fluorescence. The chromatography and mass spectroscopy analysis clearly support the labeling of the BODIPY dye on the BSA. The protein labeling with blue-emitting BODIPY would be applicable for studying protein dynamics and fluorescence resonance energy transfer (FRET) with intrinsic biomolecules.
