Double-insulated porous PDMS sponge for heat-localized solar evaporative seawater desalination
No full textSeawater desalination has a strong potential for solving global water shortage problem, and solar-based evaporative desalination technology has received increased attention. For successful solar steam generation (SSG), solar energy should be utilized in a balanced manner through heat localization. In this study, we propose a sucrose‑carbonized sugar-templating polydimethylsiloxane (PDMS) sponge sealed with ethyl vinyl acetate (EVA) foam, called as C-STP sponge. The C-STP sponge consists of a double-layered porous structure with carbonaceous material on the top surface. The C-STP sponge exhibits high SSG performance in long-term operation with anti-salt fouling ability by its self-cleaning feature. Several factors governing the C-STP sponge were optimized by examining two different kinds of sugar with different porosity levels and carbonized layer thicknesses. The porous C-STP sponge has numerous micropores caused by sugar-leaching, thereby decreasing the thermal conductivity to improve the evaporation rate. The heat localization aspects of PDMS were also investigated. The highest solar evaporation was 1.53 kg m11Nsciescopu

Cellular Automata Simulation for Modeling of Microstructure Evolution during Dynamic Recrystallization
No full textShimmy evaluation using theoretical multibody model and experimental techniques
No full textShimmy is the vibration in the steering rotational direction during steady-state running and gives annoyance to passengers. Passenger's comfort is a critical characteristic in vehicle. In this study, both a theoretical linear model and a numerical model are used to predict and optimize the frequencies of shimmy related modes and the level of vibration for a vehicle. A theoretical multibody linear model of 48-DOF was used for quasi-static analysis and modal analysis. The theoretical model was verified by comparing the results of modal analysis with those of a modal experiment for front suspension system using CADA-X program. The quasi-static analysis results of the theoretical model were compared with those of an ADAMS model. A full vehicle model using ADAMS was also verified with the results of the modal experiment and chassis dynamometer experiments for shimmy reproduction. From experiments and simulations, it was found that the wheel longitudinal vibration mode was the most dominant source of shimmy vibration. In addition, 13 design parameters of the front suspension system including compliance and geometric factors for reducing shimmy level were selected based on the experimental results. By performing 27 orthogonal simulations using Taguchi methodology, an optimal combination of design parameters was constructed. Through modal analysis of the theoretical model with the optimized design parameters, it was found that the wheel longitudinal vibration mode changed into two local vibration modes. Finally, a simulation of the numerical model verified that the suggested design parameters resulted in shimmy vibration reduction.N

Analysis of PDZ domain interactions using yeast two-hybrid and coimmunoprecipitation assays
No full textThe PDZ domain is a protein-protein interaction module that interacts with a C-terminal short peptide motif in its binding partners. A variety of methods have been used to study PDZ domain interactions. This chapter details the two methods most commonly used in the analysis of PDZ interactions: yeast two-hybrid and coimmunoprecipitation assays. In addition, we discuss the features that must be considered for an efficient analysis of PDZ interactions
