Author is Camasso, Nicole M.; Sanford, Melanie S..

Homogeneous nickel catalysis is used for the synthesis of pharmaceuticals, natural products, and polymers. These reactions generally proceed via nickel intermediates in the Ni0, NiI, NiII, and/or NiIII oxidation states. In contrast, NiIV intermediates are rarely accessible. Authors report herein the design, synthesis, and characterization of a series of organometallic NiIV complexes, accessed by the reaction of NiII precursors with the widely used oxidant S-(trifluoromethyl)dibenzothiophenium triflate. These NiIV complexes undergo highly selective carbon(sp3)-oxygen, carbon(sp3)-nitrogen, and carbon(sp3)-sulfur coupling reactions with exogenous nucleophiles. The observed reactivity has the potential for direct applications in the development of nickel-catalyzed carbon-heteroatom coupling reactions.

Compound: Potassiumtris(1-pyrazolyl)borohydride, is researched, Molecular C9H10BKN6, CAS is 18583-60-3, about Two-stage hybrid constructed wetland-microbial fuel cells for swine wastewater treatment and bioenergy generation. Author is Ren, Baiming; Wang, Tongyue; Zhao, Yaqian.

A newly emerged alum sludge-based hybrid constructed wetland-microbial fuel cells (CW-MFCs), i.e. vertical upflow CW coupled MFC as 1st stage and horizontal subsurface flow CW coupled MFC as 2nd stage (VFCW-MFC + HSSFCW-MFC), was firstly developed for swine wastewater treatment and electricity generation. Swine wastewater and multi-set air-cathodes were applied to investigate the pollutants removal behavior and the power production Six-month trial suggested that the overall removal efficiency of SS, COD, NH+4-N, NO-3-N, TN, TP and PO3-4-P was 76 ± 12.4, 72 ± 7.4, 59 ± 28.3, 69 ± 25.6, 47 ± 19.7, 85 ± 9.5 and 88 ± 8.7%, resp. The two stages hybrid system (VFCW-MFC + HSSFCW-MFC) continuously generated elec. power with average voltages of 0.44 ± 0.09 and 0.34 ± 0.09 V, and power densities of 33.3 ± 13.81 and 9.0 ± 2.5 mW/m3 in 1st and 2nd stage, resp. The average net energy recovery (NER) of 1st stage and 2nd stage is in turn 0.91 ± 0.16 and 2.76 ± 0.70 Wh/kg·COD. It indicates that the hybrid CW-MFCs has higher removal efficiency than single stage CW-MFC, while 1st stage plays the major role both in pollutants removal and power generation.
