| 6 | High performance of TiO_(2)/Cu_(x)O photoelectrodes for regenerative solar energy storage in a vanadium photoelectrochemical cell显示文摘Photocatalysts for harvesting solar energy to either electricity or chemical fuels have attracted much attention recently, but they have big obstacles such as wide bandgaps and rapid charge recombinations to overcome for final applications. In this study, we investigates a useful method to utilize vanadium redox pairs, which are commonly applied for vanadium redox flow batteries, to diminish charge recombinations and thus to enhance photocurrent response in regenerative solar energy storage. The results reveal significant improvements in photocurrent density by forming cuprous and cupric oxides in TiO_(2)/Cu_(x)O electrodes under solar AM 1.5 illuminations using the vanadium photoelectrochemical storage cell at 0.025 mol L^(-1) of vanadium redox species in the acid electrolytes. In addition, the stabilized photocurrent density of the copper content optimized TiO_(2)/Cu_(x)O electrodes is almost tripled from the TiO_(2) only electrode because the charge recombinations can be mitigated with the content optimized TiO_(2)/Cu_(x)O electrodes. Therefore, the optimized TiO_(2)/Cu_(x)O electrode results in the highest charge storing performance in the catholyte chamber, and the roles of vanadium redox species are also clearly demonstrated. | Harin Yoo Doohwan Lee Jung Hyeun Kim | 2022 | Green Energy & Environment2022，7，4： | 0 |
| 7 | SYSTEM ENTITY STRUCTURES FOR SUITES OF SIMULATION MODELS显示文摘We describe how to develop a suite of models in the MS4 Modeling Environment(MS4 Me).The approach employs the operation of merging of System Entity Structures supported by the environment.After construction,the suite of models can be hosted on Model Store,the cloud-based repository of models provided by MS4 systems as a basis for further collaborative model development.A suite of models,relating to Health Care is used as an example.In this paper,we review basic concepts of the SES needed to support of suites of simulation models.We then consider the concept of multiple aspects that provides more advanced capabilities to construct and manipulate suites of models.With this background,we go on to discuss a methodology for developing suites of simulation models and cloud-based technology for storing and sharing such models in a marketplace of models.Finally,we discuss future research and developments needed to bring the marketplace into common use by modeling and simulation practitioners. | BERNARD P.ZEIGLER CHUNGMAN SEO DOOHWAN KIM | 2013 | International Journal of Modeling, Simulation, and Scientific Computing2013，4，3： | 0 |
