Summary: This paper proposes a simple and effective liquid cooling structure that achieves high cooling efficiency with fewer components and lightweight aluminum plates. Numerical simulation results show that this structure effectively alleviates edge-overcooling phenomenon and optimization of inlet velocity and aluminum plate thickness can improve the cooling performance to a level comparable to traditional complex structures. This simple structure has a lower weight percentage and can be easily expanded to battery modules with different specifications, particularly those aiming for lightweight and high cooling performance.

Summary: Battery thermal management system (BTMS) maintains optimal temperature and temperature difference of Lithium-ion batteries (LiBs). This paper proposes three kinds of liquid cooling plates with mesh structures (LCP-MSs) and compares them with LCP with straight channel (LCP-SC). Results show that LCP-MSs effectively improve temperature uniformity and reduce heat concentration. Among the proposed LCP-MSs, LCP with drop-shaped deflectors (LCP-DD) stands out in reducing pressure drop (AP) of coolant. Cooling performance between LCP-DD and the other LCP-MSs is similar. Additionally, the study investigates the influence of structural parameters, number of deflectors, layout of deflectors, and inlet velocity on the cooling performance and AP of LCP-DD. An orthogonal test is carried out to optimize the design, achieving control of maximum temperature, maximum temperature difference, and pressure drop at 301.3 K, 3.1 K, and 251 Pa, respectively.

Summary: In this study, a hybrid liquid cold plate design with Z-type parallel cooling channel and PCM/aluminum foam composite, along with a delayed cooling strategy, is proposed for battery thermal management systems. Nine different cold plate designs, including one baseline cold plate without PCM composite and eight hybrid cold plates with PCM composite, are systematically analyzed to demonstrate the superior cooling performance of the proposed design. The results show that the optimum hybrid cold plate design can achieve a significant reduction in the total pumping power while maintaining the same cooling performance compared to the baseline cold plate at different battery discharge rates.

Summary: Organic donor-acceptor-donor (D-A-D) polymers or small molecules are extensively examined in organic solar cells for their favorable properties. However, the study of conjugated small molecules with D-A-D structures as photocatalytically active materials is limited. This research demonstrates that the photocatalytic activity can be influenced by tuning the donor and acceptor units. In particular, the EBE trimer exhibits the best photophysical, chemical, and photocatalytic properties compared to other D-A-D combinations. The results suggest that organic small molecules with D-A-D structures offer new potential for efficient solar-to-chemical energy conversion.

Summary: In the past decade, there has been a growing interest in studying energy systems for the combined management of power vectors. Most of the published works focus on finding the optimal design and operations of Multi Energy Systems (MES). However, for newcomers to this field, understanding how to achieve the desired optimization details while controlling computational expenses can be challenging and time-consuming. This paper presents a novel approach to analyzing the existing literature on MES, with the aim of guiding practical development of MES optimization. Through the discussion of six case studies, the authors provide a mathematical formulation as a reference for building the model and emphasize the impact of different aspects on the problem nature and solver selection. In addition, the paper also discusses the different approaches used in the literature for incorporating thermal networks and storage in the optimization of multi-energy systems.

Summary: This paper investigates the heat transfer mechanism and factors influencing thermal radiation in the process of supercritical water gasification (SCWG) of coal, and proposes a comprehensive numerical model to simulate the process. Experimental validation results show that thermal radiation accounts for a significant proportion of the total heat exchange in the reactor and a large amount of radiant energy exists in the important spectral range of supercritical water. Enhancing radiative heat transfer can effectively increase the temperature of the reaction medium and the gasification rate.

Summary: Pulsating Heat Pipes (PHP) are passive two-phase heat transfer devices with a simple structure and high heat transfer capabilities. The actual unpredictability of their dynamic behavior during startup and thermal crisis hinders their large-scale application. An experimental apparatus is designed to investigate these phenomena systematically. The results show that increasing the number of evaporator sections and condenser temperature improves the performance of PHP. The condenser temperature also affects the initial liquid phase distribution and startup time.
