“…The reaction rules behave the same way as that of nitrobenzene, and the conversion rates reach 94 % and 95 %, respectively. To showcase the versatility of the system, tests are conducted using Pd NPs loaded C 3 N 4 (Pd/C 3 N 4 ) [50] as the catalyst, with samples taken every 10 minutes over a duration of 50 minutes (Figure S36). Furthermore, we added a series of data utilizing TpPa−COF, [51] a reported COF, loaded Pd NPs as the catalyst to explore the impact of π–π interactions on reaction efficiency.…”

Microplatform with timed automata has been leveraged for guiding the preparation of molecules, whereas the requirement of handling expertise and sophisticated instrument is inevitable in combination with heterogeneous catalysis. Here we report a microfluidic‐based autolab with open structures, called Put & Play Automated Microplatform (PPAM). It shows the efficient hydrogenation performance of palladium nanoparticles on the triphenylene‐based covalent organic frameworks (Pd/TP‐COFs) in which the π–π interactions of TP rings in the vicinity of Pd is optimized by easy change‐over of catalyst and simple tuning of reactor geometries in PPAM. Using experiment/simulation of the Pd/TP‐COFs coating (PCC) and mixing (PCM) across PPAM with different channel sizes, the turnover frequencies are 60 times the commonly used batch reactor, and aniline productivity of 8.8 g h−1 is achieved in 0.09 cm3. This work will raise awareness about the benefits of the catalyst‐loaded microplatform in future materials performance campaigns.

“…Many other novel header designs [96,[100][101][102] have also been proposed and tested, as summarized in the review paper by Ghani et al [54]. Besides modifying the inlet/outlet header shapes, studies have been performed on adding obstacles inside the header to address the issue of flow maldistribution, including staggered pin-fin array (Figure 11a) [103], non-uniform-sized mini-inlet baffle (Figure 11b) [104,105], thin layers of porous media [106], and optimized manifold configurations (Figure 11c) [107]. The geometry of the heat sink channel has also been considered as a design parameter to adjust flow distribution.…”

This paper presents a detailed literature review on the thermal management issue faced by electronic devices, particularly concerning uneven heating and overheating problems. Special focus is given to the design and structural optimization of heat sinks for efficient single-phase liquid cooling. Firstly, the paper highlights the common presence and detrimental consequences of electronics overheating resulting from multiple heat sources, supported by various illustrative examples. Subsequently, the emphasis is placed on single-phase liquid cooling as one of the effective thermal management technologies for power electronics, as well as on the enhancement of heat transfer in micro/mini channel heat sinks. Various studies on the design and structural optimization of heat sinks are then analyzed and categorized into five main areas: (1) optimization of channel cross-section shape, (2) optimization of channel flow passage, (3) flow distribution optimization for parallel straight channel heat sinks, (4) optimization of pin-fin shape and arrangement, and (5) topology optimization of global flow configuration. After presenting a broad and complete overview of the state of the art, the paper concludes with a critical analysis of the methods and results from the literature and highlights the research perspectives and challenges in the field. It is shown that the issue of uneven and overheating caused by multiple heat sources, which is commonly observed in modern electronics, has received less attention in the literature compared to uniform or single-peak heating. While several design and structural optimization techniques have been implemented to enhance the cooling performance of heat sinks, topology optimization has experienced significant advancements in recent years and appears to be the most promising technology due to its highest degree of freedom to treat the uneven heating problem. This paper can serve as an essential reference contributing to the development of liquid-cooling heat sinks for efficient thermal management of electronics.

“…The pressure drop increase in the parallel channels section is difficult to avoid because of some narrowed channel inlets and tailored non-uniform flow distribution, for the purpose of more efficient cooling. Nevertheless, for the pressure drops in distributing and collecting manifolds, some better header designs [44] may be considered to reduce the total pressure drop. Note that the proposed optimization method is compatible with other manifold shapes.…”
