Amine absorption has been regarded as an efficient solution in reducing the atmospheric carbon dioxide (CO2) concentration. Machine learning (ML) models are applied in the CO2 capture field to predict the CO2 solubility in amine solvents. Although there are other similar reviews, this systematic review presents a more comprehensive review on the ML models and their training algorithms applied to predict CO2 solubility in amine-related solvents in the past 10 years. A total of 55 articles are collected from Scopus, ScienceDirect and Web of Science following Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Neural network is the most frequently applied model while committee machine intelligence system is the most accurate model. However, relatively the same optimisation algorithm was applied for each type of ML models. Genetic algorithm has been applied in most of the discussed ML models, yet limited studies were found. The advantages and limitations of each ML models are discussed. The findings of this review could provide a database of the data points for future research, as well as provide information to future researchers for studying ML application in amine absorption, including but not limited to implementation of different optimisation algorithms, structure optimisation and larger scale applications.
胺吸收被认为是降低大气中二氧化碳浓度的有效方法。机器学习（ML）模型应用于二氧化碳捕获领域，用于预测二氧化碳在胺类溶剂中的溶解度。尽管还有其他类似的综述，但本系统综述对过去10年来用于预测二氧化碳在胺相关溶剂中的溶解度的ML模型及其训练算法进行了更全面的综述。根据系统评价和荟萃分析指南的首选报告项目，从Scopus， ScienceDirect和Web of Science中收集了55篇文章。神经网络是应用最广泛的模型，而委员会机器智能系统是应用最准确的模型。然而，相对相同的优化算法应用于每种类型的ML模型。遗传算法已经应用于大多数讨论的机器学习模型中，但研究有限。讨论了各种机器学习模型的优点和局限性。本综述的研究结果可以为未来的研究提供数据点数据库，并为未来的研究人员研究ML在胺吸收中的应用提供信息，包括但不限于实现不同的优化算法，结构优化和更大规模的应用。

Machine learning (ML) offers promising new approaches to tackle complex problems and has been increasingly adopted in chemical and materials sciences. In general, ML models employ generic mathematical functions and attempt to learn essential physics and chemistry from large amounts of data. The reliability of predictions, however, is often not guaranteed, particularly for out-of-distribution data, due to the limited physical or chemical principles in the functional form. Therefore, it is critical to quantify the uncertainty in ML predictions and understand its propagation to downstream chemical and materials applications. This review examines existing uncertainty quantification (UQ) and uncertainty propagation (UP) methods for atomistic ML under the framework of probabilistic modeling. We first categorize the UQ methods and explain the similarities and differences among them. Following this, performance metrics for evaluating their accuracy, precision, calibration, and efficiency are presented, along with techniques for recalibration. These metrics are then applied to survey existing UQ benchmark studies that use molecular and materials datasets. Furthermore, we discuss UP methods to propagate uncertainty in widely used materials and chemical simulation techniques, such as molecular dynamics and microkinetic modeling. We conclude with remarks on the challenges and opportunities of UQ and UP in atomistic ML.

This paper offers a comprehensive review of previous studies and articles on international standards and certification criteria for biodegradable plastics. It highlights key insights into the biodegradation environment and certification processes for these materials. As various countries and organizations intensify research efforts on biodegradable plastics, certification standards for biodegradability are evolving and expanding. This trend is expected to play a pivotal role in shaping international standards. Nonetheless, several challenges persist, including the absence of universally recognized testing methods, inconsistencies between real-world and laboratory biodegradation conditions, and a lack of clear definitions and standardized criteria. Above all, establishing international standards is critical to advancing biodegradable plastics as a viable alternative to conventional plastics.

A review of the available information about the packed bed reactors with cocurrent upflow of gas and liquid (UFRs), particularly focused on heat transfer with an external medium through the container wall, was undertaken in this contribution. The typical use of such reactors is summarized as well as some novel applications. A brief discussion about fluid-dynamics is also made due to its strong effect on the transport processes. Experimental setup, available data, and literature correlations of heat transfer parameters are thoroughly reviewed. From a critical analysis of the experimental data, a refined database has been built, which allows comparing the performance of the existing correlations for the two parameters of the extensively employed two-dimensional pseudo-homogeneous plug flow model (i.e., effective radial thermal conductivity and wall heat transfer coefficient). In addition, new correlations for these parameters have been developed, which allow improving the actual predictive capabilities. Finally, the global heat transfer between the bed and the wall was comparatively analyzed for upflow (UFRs) and downflow (TBRs) gas–liquid packed bed reactors.

Considering the distinctive features of the delayed coking process and taking into account various particulate matter control technologies, the feasibility of using jet washing technology to remove coke powder from process gas is explored. The performance of scrubbers is heavily reliant on the quality of atomization, which in turn is influenced by liquid jet breakup. Due to the multiple interactions of various instabilities involved in jet breakup, as well as the short duration and small scale of this process, it is challenging to observe experimentally. Therefore, the specific fluid dynamics processes are not yet clear. In recent years, extensive research has been conducted on research methods, jet breakup modes, jet breakup characteristics, and jet breakup mechanisms. However, there is a lack of comprehensive review work summarizing these research advancements. This article aims to provide a comprehensive overview to facilitate jet scrubber designers’ systematic understanding of progress in jet breakup research. Furthermore, it discusses the significance of studying confined spaces for jet breakup with the objective of providing valuable insights for designing and optimizing delayed coker.

Despite concerns regarding safety, economics, and the environment, lithium-ion batteries (LIBs) are considerably utilized on account of their low energy density and capacity. Li–sulfur (Li–S) batteries have become a promising substitute for LIBs. Here, we first compared both systems in their cons and pros and analyzed the leading countries and companies in Li–S research are assessed through the utilization of an academic database. The scope of our research includes performance-enhancing design elements, cathode components, and binder materials. Synthetic and natural binders are trialed in an effort to enhance Li–S performance. Understanding the fundamental mechanisms enables the development of durable cathodes and binders. To overcome obstacles such as polysulfide adsorption, shuttle effect, and ion transport limitations, conducting polymers, metal/metal oxides, carbon-based compounds, MOFs, and Mxenes are investigated as potential cathode materials. In addition to pore characteristics and active polar sites, the efficacy of a battery is influenced by the anode surface geometry and heteroatom doping. Our review indicates that binders and sulfur/host composites must be meticulously chosen for Li–S battery cathode materials. This research advances energy storage technology by establishing the foundation for economically viable lithium–sulfur batteries with superior performance.

In the spotlight of successful breakthrough of the COVID-19 mRNA vaccines, lipid nanoparticles are becoming an important vehicle to deliver a variety of therapeutics. The encapsulation of mRNA using lipids is a self-organizing process that necessitates fast mixing to achieve uniform supersaturation. This is achieved in a confined impinging jet reactor (CIJR) where two input jets collide and fast mix in the mixing chamber. While CIJR is not a new mixing technology, it stands out for its capability to achieve mixing times below a millisecond. This study presents a critical review of major studies concerning CIJRs, starting with the CIJRs’ structures and flow characterization, through experimental and numerical studies, and closing with successful applications in a wide range of chemical/pharmaceutical processes. The detailed mixing principles, scaling-up, and mechanisms of making nanoparticles are discussed focusing mainly on the hydrodynamic aspect. The objective of the review is to supply essential information for the optimized design and operation of CIJRs, catering to both industry and academia.
