Enhancing photosynthetic production of ethylene in genetically engineered Synechocystis sp. PCC 6803

15-10-2014 | Tao Zhu; Xiaoman Xie; Zhimin Li; Xiaoming Tan; Xuefeng Lu, Green Chemistry, 2014

Ethylene is widely used in the petrochemical industry and has traditionally been produced via the steam cracking of petroleum-based feedstock. The exploration of sustainable and carbon-neutral methods of producing ethylene from the renewable feedstock seems promising. The direct photosynthetic ...


Enhancement of ORR Catalytic Activity by Multiple Hetero-atom Doped Carbon Materials

15-10-2014 | Dae-wook Kim; Oi Lun Li; Nagahiro Saito, Physical Chemistry Chemical Physics, 2014

Hetero-atom doped carbon matrix has been attracting numerous attentions due to superior electrochemical stability, light weight and low cost. Hence, in this study, various type of hetero-atom, including single dopants of N, B, P and multiple dopants of B-N and P-N with carbon matrix was ...


Evaluating different classes of porous materials for carbon capture

15-10-2014 | Johanna Maria Huck; Li-Chiang Lin; Adam Berger; Mahdi Niknam Shahrak; Richard Luis Martin; Abhoyjit Bhown; Maciej Ha ..., Energy & Environmental Science, 2014

Carbon Capture and Sequestration (CCS) is one of the promising ways to significantly reduce the CO2 emission from power plants. In particular, amongst several separation strategies, adsorption by nano-porous materials is regarded as a potential means to efficiently capture CO2 at the place of its ...


Electron Transport in All-Carbon Molecular Electronic Devices

15-10-2014 | Richard L McCreery; Adam Johan Bergren; Amin Morteza-Najarian; Sayed Y. Sayed; Haijun Yan, Faraday Discussions, 2014

Carbon has always been an important electrode material for electrochemical applications, and the relatively recent development of carbon nanotubes and graphene as electrodes has significantly increased interest in the field. Carbon solids, both sp2 and sp3 hybridized, are unique in their ...


Nitrogen-doped CeOx nanoparticles modified graphitic carbon nitride for enhanced photocatalytic hydrogen production

15-10-2014 | Jie Chen; Shaohua Shen; Po Wu; Liejin Guo, Green Chemistry, 2014

Nitrogen-doped CeOx nanoparticles (N-CeOx NPs) were directly formed on graphitic carbon nitride (g-C3N4) via a facile one-pot method by annealing a mixture of Ce(NO3)3 and melamine as CeOx and g-C3N4 precursors, respectively. Nitrogen was in situ doped into CeOx under NH3 atmosphere released by ...


A cation-directed two-component cascade approach to enantioenriched pyrroloindolines

15-10-2014 | Jamie R. Wolstenhulme; Alex Cavell; Matija Gredičak; Russell W. Driver; Martin D. Smith, Chemical Communication, 2014

A cascade approach to complex pyrroloindolines bearing all-carbon quaternary stereocentres has been developed. This two-component process uses a chiral ammonium salt to control diastereo- and enantioselectivity in the addition of isocyanides to functionalized alkenes to afford pyrroloindolines ...


Simultaneous sensing of intracellular microRNAs with a multi-functionalized carbon nitride nanosheet probe

15-10-2014 | Xianjiu Liao; Quanbo Wang; Huangxian Ju, Chemical Communication, 2014

A multi-functionalized CNNS probe was designed by loading different dye-ssDNAs and folate on CNNSs, which was used for in situ fluorescence imaging and sensing of intracellular multiple microRNAs.


The electronic structure of perfluorodecalin studied by soft X-ray spectroscopy and electronic structure calculations

15-10-2014 | T. Brandenburg; M. Agåker; K. Atak; M. Pflüger; C. Schwanke; T. Petit; K. M. Lange; J.-E. Rubensson; E. F. Aziz, Physical Chemistry Chemical Physics, 2014

Fluorine and carbon K absorption and emission spectra of liquid perfluorodecalin are presented and analyzed in terms of density functional calculations–configuration interaction. A comprehensive view of the electronic structure is given, and site-specific intramolecular interactions are ...
