THEORETICAL MECHANISTIC STUDY OF METALLAPHOTOREDOX CATALYSIS: C–N CROSS-COUPLING VIA NI(II)-MEDIATED σ-BOND METATHESIS

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), gio 02 luglio 2020 C–N cross-coupling reaction has been achieved by photoredox-mediated iridium/nickel dual catalysis, but its mechanism is still controversial in these reactions. Theoretical mechanistic study of a highly chemoselective C–N cross-coupling of pyrrolidine with 4-bromobenzotrifluoride has been performed by density functional theory (DFT)......

IN SITU CONSTRUCTION AND POST-ELECTROLYSIS STRUCTURAL STUDY OF POROUS NI2P@C NANOSHEET ARRAYS FOR EFFICIENT WATER SPLITTING

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mar 30 giugno 2020 In this study, the porous hybrid catalyst with carbon-confined Ni2P porous nanosheet arrays supported on nickel foam (Ni2P@C NAs/NF) was developed via a one-step phosphorization of NiMOF precursor. Remarkably, the as-fabricated Ni2P@C NAs/NF exhibited superior oxygen evolution reaction (OER) performance and......

UPTAKE, TRANSLOCATION AND ACCUMULATION OF NICKEL AND COBALT IN BERKHEYA CODDII, A ‘METAL CROP’ FROM SOUTH AFRICA

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mer 17 giugno 2020 Hyperaccumulator plants have the ability to efficiently concentrate metallic elements, e.g. nickel, from low-grade sources into their living biomass. Although the majority of nickel hyperaccumulator plant species restrict cobalt uptake, some species are able to co-accumulate cobalt when growing in ultramafic......

TREND: ENTERING THE NICKEL AGE OF SUPERCONDUCTIVITY

Redazione
(AGENPARL) – WASHINGTON (D.C.), gio 28 maggio 2020 The Hwang team’s discovery did not come out of the blue. For decades, researchers have proposed other (non-copper) oxides as high- Tc candidates, the idea being that studying these cuprate analogs would lead to a better understanding of high-temperature superconductivity itself. In......

NEAR-INFRARED LIGHT-RESPONSIVE UCST-NANOGELS USING AN EFFICIENT NICKEL-BIS(DITHIOLENE) PHOTOTHERMAL CROSSLINKER

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mer 20 maggio 2020 A new kind of near-infrared (NIR) light-responsive polymer nanogels is demonstrated. The micellar aggregates of an ABA-type triblock copolymer, whose core is a thermosensitive polymer displaying an upper-critical-solution-temperature (UCST), are crosslinked using a photothermal nickel-bis(dithiolene) complex that absorbs NIR light and......
