Identification of M‐NH2‐NH2 Intermediate and Rate Determining Step for Nitrogen Reduction with Bioinspired Sulfur‐Bonded FeW Catalyst

Angewandte Chemie, Volume 133, Issue 37, Page 20494-20504, September 6, 2021., 2021
Inspired by biological nitrogenases, a bimetallic sulfide material (FeWSx@FeWO4) was synthesized for a highly efficient N2 reduction (NRR) catalyst. In situ Raman spectra and hydrazine reduction kinetics analysis revealed that the reduction of undissociated hydrazine intermediates (M‐NH2‐NH2) on the surface of catalyst is the rate‐determing step for ...

Evidence for the N′(1720)3/2+ nucleon resonance from combined studies of CLAS π+π−p photo- and electroproduction data

Physics Letters B, 2020
The analysis of the nine 1-fold differential cross sections for the γr,vp→π+π−p photo- and electroproduction reactions obtained with the CLAS detector at Jefferson Laboratory was carried out with the goal to establish the contributing resonances in the ...

Suppressing the liquid product crossover in electrochemical CO2 reduction

SmartMat, Volume 2, Issue 1, Page 12-16, March 2021., 2021
Here we review promising methods to suppress liquid product crossover in flow cell reactor including the use of bipolar membranes, solid‐state electrolytes, and cation‐exchange membranes based acidic CO2R systems. The elimination of liquid product crossover is thus a key step to advance the achievement of renewable liquid fuels from CO2 Abstract ...

An Effective Harmonic Suppression Method Based on Linear Active Disturbance Rejection Control for Copper Electrowinning Rectifier

Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021
Because the harmonics in the production process of copper electrowinning have an important impact on the electrical energy consumption, it is necessary to suppress the harmonics effectively. In this paper, a copper electrowinning rectifier with double inverse star circuit is selected as a study object in which a large number of harmonics mainly ...

Electroexcitation of the P33(1232), P11(1440), D13(1520), S11(1535) at Q^2=0.4 and 0.65(GeV/c)^2 [PDF]

, 2004
Using two approaches: dispersion relations and isobar model, we have analyzed recent high precision CLAS data on cross sections of \pi^0, \pi^+, and \eta electroproduction on protons, and the longitudinally polarized electron beam asymmetry for p(\vec{e},

Production of Polarized Vector Mesons off Nuclei [PDF]

, 2007
Using the light-cone QCD dipole formalism we investigate manifestations of color transparency (CT) and coherence length (CL) effects in electroproduction of longitudinally (L) and transversally (T) polarized vector mesons.

Exclusive diffractive processes and the quark substructure of mesons [PDF]

, 1996
Exclusive diffractive processes on the nucleon are investigated within a model in which the quark-nucleon interaction is mediated by Pomeron exchange and the quark substructure of mesons is described within a framework based on the Dyson-Schwinger ...

Electroproduction of baryon–meson states and strangeness suppression

Physics Letters B, 2016
We describe the electroproduction ratios of baryon–meson states from nucleon, inferring from the sea quarks in the nucleon using an extension of the quark model that takes into account the sea.

An improved hadronic model for pion electroproduction

Physics Letters B, 2020
Current measurements of the high energy behavior of the pion form factor are obtained from pion electroproduction data. These values are model dependent, utilizing the Vanderhaeghen, Guidal and Laget Regge (VGL) Model for their extraction.
