Redox Properties of Flavin in BLUF and LOV Photoreceptor Proteins from Hybrid QM/MM Molecular Dynamics Simulation
Flavins play an important role in many oxidation and reduction processes in biological systems. For example, flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN) are common cofactors found in enzymatic proteins that use the special redox prope ...
Amer Chemical Soc2024Realization of Organocerium-Based Fullerene Molecular Materials Showing Mott Insulator-Type Behavior
Electron-rich organocerium complexes (C5Me4H)(3)Ce and [(C5Me5)(2)Ce(ortho-oxa)], with redox potentials E-1/2 = -0.82 V and E-1/2 = -0.86 V versus Fc/Fc(+), respectively, were reacted with fullerene (C-60) in different stoichiometries to obtain molecular m ...
Amer Chemical Soc2024A pre-fatigue training strategy to stabilize LiCoO2 at high voltage
Lei Zhang, Kangning Zhao, Rui Xia
Layered cathodes are among the most promising cathodes for high-energy-density Li-ion batteries, yet hindered by the structural degradation from both bulk strain and surface oxygen loss at high voltage (above 4.5 V). Herein, we report a pre-fatigue trainin ...
Cambridge2024Electrochemical-repaired porous graphene membranes for precise ion-ion separation
Kumar Varoon Agrawal, Kuang-Jung Hsu, Shuqing Song, Kangning Zhao, Heng-Yu Chi, Zongyao Zhou
The preparation of atom-thick porous lattice hosting & Aring;-scale pores is attractive to achieve a large ion-ion selectivity in combination with a large ion flux. Graphene film is an ideal selective layer for this if high-precision pores can be incorpora ...
Nature Portfolio2024Spatially Explicit Linkages Between Redox Potential Cycles and Soil Moisture Fluctuations
Andrea Rinaldo, Rizlan Bernier-Latmani, Paolo Benettin, Manon Frutschi, Simiao Wang, Filippo Miele, Mitra Asadollahi
Reduction-oxidation cycles measured through soil redox potential (Eh) are associated with dynamic soil microbial activity. Understanding changes in the composition of, and resource use by, soil microbial communities requires Eh predictability under shiftin ...
2023A colloidal aqueous electrolyte modulated by oleic acid for durable zinc metal anode
Kangning Zhao, Xu Zhang, Di Yang
Continuous dendrites growth, as well as corrosion and side reactions of Zn metal anode seriously hinder the development of aqueous zinc ion batteries. To address these issues, oleic acid (OA) is dispersed into a 2 M ZnSO4 solution to form a novel colloidal ...
ELSEVIER SCIENCE SA2023Graphene nanoplatelets promoted CoO-based catalyst for low temperature CO2 methanation reaction
Thi Ha My Pham, Youngdon Ko, Liping Zhong
Methanation of CO2 is an important reaction for reducing CO2 emissions in a power-to-gas system. Compared to cobalt supported on gamma-Al2O3, cobalt supported on graphene nanoplatelets (GNPs) showed significantly better performance for CO2 methanation. Cob ...
FRONTIERS MEDIA SA2023Origin of the Activity Trend in the Oxidative Dehydrogenation of Ethanol over VOx/CeO2
Rob Jeremiah G. Nuguid, Anna Zabilska, Olga Safonova
Supported vanadia (VOx) is a versatile catalyst for various redox processes where ceria-supported VOx have shown to be particularly active in the oxidative dehydrogenation (ODH) of alcohols. In this work, we clarify the origin of the volcano-shaped ethanol ...
WILEY-V C H VERLAG GMBH2023Multielectron Redox Chemistry of Uranium by Accessing the plus II Oxidation State and Enabling Reduction to a U(I) Synthon
Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic, Anne-Sophie Chauvin
Thesynthesis of molecular uranium complexes in oxidation stateslower than +3 remains a challenge despite the interest for their multielectrontransfer reactivity and electronic structures. Herein, we report theone- and two-electron reduction of a U(III) com ...
AMER CHEMICAL SOC2023Development of new volcano-shaped microelectrodes for single cell electrochemistry, electrophysiology and impedance studies.
Micro- nano-electrodes have demonstrated superior performances in measuring attenuated intracellular action potentials from electrogenic cell cultures compared to traditional multi-electrode arrays. Yet, the understanding of the critical electrode features ...
