The subject of this research has been the focus of worldwide investigation for several decades, resulting in ongoing challenges and opportunities for researchers and engineers in control systems. One particularly interesting case arises when, over the course of a day, there is an imbalance in the traffic flow between two opposing directions of travel. A reversible lane control system may be the solution to alleviate congestion and improve traffic flow in this scenario. The application of reversible lane systems to mitigate traffic congestion and improve mobility has been a global practice since the 1930s, encompassing various road types. This research area, developed over recent decades by numerous international research groups, presents ongoing challenges and opportunities, thus inspiring the transportation engineering community. The rapid progress in autonomous and connected vehicle technology signals a transformative period for road traffic. In this context, it would be beneficial to conduct a comprehensive survey of established lane reversal control methods for traffic networks. This initiative would provide researchers with valuable resources to effectively address the challenges of future traffic management. Recent advancements in traffic control, such as static and dynamic lane reversal and the innovative internal boundary control for the lane-free paradigm, are reviewed in this paper, focusing on bidirectional capacity sharing.

Alloy element doping is a key strategy to enhance the thermomechanical properties of Mg-Li alloys, and first-principles calculations based on density functional theory (DFT) have become an important means to explore the doping strengthening mechanism. However, most existing studies adopt a top-down analysis approach, and the explanation of the strengthening mechanism of doped atoms is still shallow, failing to fully leverage the economic and efficiency advantages of computer-aided technology. This work systematically sorts out the core role of DFT in explaining the strengthening mechanism of metals, and through the construction of theoretical models and simulation calculations, reveals the electronic structure and chemical bond change rules at the atomic scale; it focuses on reviewing how DFT has helped to analyze the influence mechanisms of different doped elements on the crystal structure, mechanical properties, and corrosion resistance of Mg-Li alloys during their development process; and it discusses the application of DFT in the functional design of Mg-Li alloys. The research points out that the current application of DFT has limitations such as insufficient multi-scale coupling analysis and lagging experimental verification. Therefore, it is proposed to combine molecular dynamics simulation and high-throughput computing to provide theoretical support for the precise design and industrial application of doping strengthening of Mg-Li alloys, which has important scientific significance and practical value for promoting the development of the lightweight materials field.</div></div>","PeriodicalId":36919,"journal":{"name":"Results in Engineering","volume":"27 ","pages":"Article 106173"},"PeriodicalIF":6.0,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144604589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notwithstanding, the commercialization of these technologies is impeded by the sluggish kinetics associated with the oxygen evolution reaction (OER) occurring at the air cathode. This particular challenge has conventionally been addressed by employing expensive noble metal catalysts, including platinum and iridium. The incorporation of these materials significantly escalates both the overall system costs and the associated carbon emissions. In light of this, recent research endeavors have investigated the feasibility of employing waste-derived non-noble metal catalysts as sustainable and economically advantageous alternatives. This examination provides a meticulous evaluation of the latest developments (2019–2025) related to the synthesis, characterization, and efficacy of catalysts derived from industrial byproducts, electronic waste, depleted batteries, and biomass residues. Empirical studies demonstrate that optimized Fe/Co/Ni-based catalysts derived from waste can enhance OER efficiency by up to 40%, prolong ZAB cycle life by exceeding 5000 cycles, and reduce catalyst expenses by up to 50% compared to noble metals. Life cycle assessment (LCA) findings indicate that these methodologies contribute to a reduction in the overall carbon footprint by approximately 25%. Principal synthesis techniques, including Pyrolysis, hydrothermal treatment, and sol-gel processing, are evaluated in terms of efficiency, scalability, and environmental ramifications. Structural and electrochemical properties are scrutinized using advanced methodologies, including scanning electron microscopy (SEM), transmission electron microscopy (TEM), Brunauer-Emmett-Teller (BET) analysis, and <em>in situ</em> spectroscopy. The review also highlights pilot-scale demonstrations and examines AI-driven catalyst design as an innovative approach to this field. Ultimately, the study identifies significant obstacles, including compositional variability, impurity management, and constrained industrial applications, while proposing future trajectories for the development of ZABs guided by circular economy principles. This positions waste-derived catalysts as a feasible avenue for sustainable and scalable energy storage solutions.</div></div>","PeriodicalId":36919,"journal":{"name":"Results in Engineering","volume":"27 ","pages":"Article 106161"},"PeriodicalIF":6.0,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144604669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, to improve indoor environmental quality (IEQ) in school classrooms, four performance goals (PG) should be considered. These goals include reducing energy consumption, ensuring overall comfort, promoting occupant health, and enhancing student productivity. Ten holistic approach design methods (HAD) were identified to achieve these objectives. Despite the significant attention this field has garnered, there is uncertainty regarding the potential of different HAD types to influence the PG in various climate conditions. To address this uncertainty, 135 papers were reviewed across nine databases. This paper demonstrates the combined IEQ and key PG on enhancing classrooms through a systematic literature review and bibliometric analysis conducted to assess the development of this field. Then, the investigated HAD was introduced into PG in different climate zones. The review revealed that almost all HAD tested in the temperate zone (C) successfully achieved the goals. Conversely, tropical (A), dry (B), and cold (D) zones faced significant environmental challenges, complicating the implementation and effectiveness of these HAD. This review concluded that enhancing classrooms’ IEQ with HAD necessitates comprehensively considering multiple HADs rather than individual ones. Furthermore, most studies in climates A, B, and D have only focused on a few HAD aspects, resulting in substantial variations in the depth of research among different HAD categories and the applicability of PG in different climate zones. The result guides the selection of an appropriate HAD that is suitable for various climate zones to achieve PG and better IEQ in classrooms.</div></div>","PeriodicalId":36919,"journal":{"name":"Results in Engineering","volume":"27 ","pages":"Article 106082"},"PeriodicalIF":6.0,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144604670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, the transformation is shifted from a permanent implant to a temporary implant, which is a bioabsorbable metallic implant used during bone tissue healing as a mechanical support for a temporary period and subsequently degrades and eliminates the need for secondary surgery. Magnesium alloy implants have shown as a promising bioabsorbable metallic implant due to their biodegradability, biocompatibility, and mechanical behavior related to bone. However, the abiding problem of Mg-based orthopedic implants is their fast degradation rate, release of Mg²⁺ and hydrogen (which causes bubbles and delayed healing) in the human body, and mechanical failure before completion of healing, thus hindering their clinical applicability. In order to improve the above problems, several researchers have explored and applied different techniques such as alloy composition, surface modification techniques as effective and efficient ways.
