Redox‐induced configuration conversion for thioacetamide dimer can function as a molecular switch

Journal of Computational Chemistry (2010)

Haiying Liu Xiaohua Chen Yuxiang Bu

Abstract The electronic switching properties of thioacetamide dimer (TAD) were investigated using the nonequilibrium Green's function method combined with density functional theory for design of a novel molecular switch. The H‐bonded TAD can be converted upon hole‐trapping to a three‐electron (3e)‐bonded configuration with a S∴S linkage which could provide a more favorable channel for charge transfer than the before. The redox‐induced configuration conversion between the H‐bonded and the 3e‐bonded TADs could govern the charge migration through the molecular junction with a considerable difference in conduction currents. The calculated I–V characteristic curves of two configurations exhibit a switching behavior with an On‐Off ratio in a range of about 4.3–7.6 within the applied voltages. Clearly, this hypothetical scheme provides a potential way to explore the novel conformation‐dependent molecular switch. © 2010 Wiley Periodicals, Inc. J Comput Chem 2010

Research on Collaborative Optimal Configuration Method of Charging Pile and Energy Storage in Active Distribution Network Based on Double Layers and Multi-Scenarios

2021 International Conference on Power System Technology (POWERCON) (2021)

Jinjian Cai Zhiping Wang Xigen Feng Xiaohua Chen Hongye Zhang

A method to optimize the configuration of charging piles(CS) and energy storage(ES) with the most economical coordination is proposed. It adopts a two-layer and multi-scenario optimization configuration method. The upper layer considers the configuration of charging piles and energy storage. In the system coupled with the road network, the upper layer considers to improve the convenience and cost of charging electric vehicles by the charging pile configuration; the lower layer considers the operating cost of the distribution network, and reduces the operating cost of the distribution network through the economic benefits of charging piles and energy storage. Use genetic algorithm and solver Gurobi to solve. The feasibility and effectiveness of the proposed method are verified by the improved IEEE 33-node system and 25-node transportation system coupling, and the economic efficiency of the distribution network is improved through the cooperation of energy storage and charging piles.

The effect of doped fluorin on the field-emission properties of carbon nanotubes

Journal of Changsha University of Science & Technology (2007)

Xiaohua Chen

Based on the density-functional theory and the first-principle method,the field-emission properties of the opened,half-closed and closed armchair(5,5) single-walled carbon nanotubes(SCNTs) doped by fluorin element were calculated.A geometry optimization of SCNTs is performed first,then the variations of binding energy,Fermi level and the density of states(DOS) are calculated.It has been found that the binding energy of all SCNTs due to the doping increase significantly,thus the SCNTs doped by fluorin element has beautiful future in field-emission application.We also found out that the Fermi level of half-closed SCNTs doped by fluorin element increased linearly,the Fermi level of closed SCNTs doped by fluorin element increased mostly,and DOS near Fermi level was rather high,so that the closed and half-closed SCNTs doped by fluorin has more benefit than the opened SCNTs in field-emission properties.

Ultrafast Activating Strategy to Significantly Enhance the Electrocatalysis of Commercial Carbon Cloth for Oxygen Evolution Reaction and Overall Water Splitting

ChemNanoMat (2020)

Kun Huang Aiping Hu Cong Huang Yanhua Li Haifeng Zhou

Abstract It is of desirability to prepare in situ self‐supporting electrocatalysts not only to meet application requirements but also to simplify the production process of working electrodes. In this work, oxygen‐containing free‐standing carbon cloth with abundant pores (e‐CC−H 2 ) has been obtained through a facile two‐step electrochemical oxidation and hydrogen etching method. Compared to the previous activation strategies of carbon cloth (such as chemical activation), this method has the advantages of simplicity, time‐saving, low‐cost and energy‐saving. Benefiting from the abundance of defects and oxygen‐containing functional groups that are active sites for oxygen evolution reaction, the obtained e‐CC−H 2 shows excellent electrocatalytic activity, with a low overpotential of 350 mV at a current density of 10 mA cm −2 , a low Tafel slope (127 mV dec −1 ) and stable electrochemical activity. This strategy paves the way for the application of functionalized and flexible materials in the field of electrochemical energy storage.
