Summary: In the context of hydrogen technology, methanol holds great potential as a carrier and energy vector. However, it is important to obtain methanol through a CO2-neutral process. One possible solution is the photocatalytic reduction of CO2 with H2O. This opinion emphasizes the importance of control experiments, such as using isotopic labeled CO2, to confirm the source of detected methanol. The use of heterojunctions can be a viable strategy to address the issue of methanol oxidation under photocatalytic conditions.

Summary: Attachment theory suggests that secure attachment is crucial for understanding climate change mitigation, as it requires joint action and collective behavioral change. Research shows that priming attachment security can increase acceptance and perceived responsibility toward anthropogenic climate change by enhancing empathy for others, leading to increased actions to address climate change. Additionally, activating attachment security may also result in higher donations to pro-environmental groups and reduce food waste, indicating that promoting secure attachment could be an effective approach for climate change mitigation.

Summary: The relationship between individuals' eating habits and their overall health is widely acknowledged. However, discussions about food and nutrition have often been too focused on medical aspects. To address the impact of poor nutrition on health, it is important for healthcare providers to engage with patients about their relationship with food and recognize that these conversations go beyond nutrition and lifestyle. By incorporating questions about food relationships and motivators of eating into routine patient history taking, it can lead to better patient assessment and referrals. This broader cultural approach aims to enhance current discussions about food intake and establish a trusted foundation between patients and healthcare professionals.

Summary: This paper develops a new approach to study equilibrium and analyze lane policies for autonomous vehicles (AVs) at different deployment stages. By integrating Vickrey's bottleneck model into the day-to-day dynamic model, the travel cost function is modified to consider AVs' value of time reduction and gain. The evolution of lane choice behaviors is described using first-order and second-order day-to-day dynamic models. Three lane policies are proposed to accommodate AVs' development, and their impact on market penetration and travel cost is examined. Analytical solutions are obtained for traffic flow, total travel cost, and convergence time, addressing the problem of stability and convergence in the dynamic model. Numerical analysis verifies the findings and provides insights on system performance. This work sheds light on the lane choice behaviors of AVs and regular vehicles, and offers insights into appropriate lane policies for AVs.

Summary: This study presents the results of interviews with 10 Producers' Organisations (POs) in Germany and Italy to explore the factors contributing to food loss in the fruit and vegetable sector. The analysis reveals similarities in the challenges faced by Italian and German POs, particularly regarding retailers' specifications. However, differences in contract structures impact the demand planning capabilities of POs in Italy. Despite these differences, POs play a key role in enhancing farmers' bargaining power in both countries. Further research is needed to compare circumstances in other European countries and understand the identified similarities and differences.

Summary: This study proposes a combined process of reduction roasting of herb-medicine residue and oxalic acid leaching to improve the recovery efficiency of lithium from spent lithium-ion batteries. By utilizing the reducing gas produced from the pyrolysis of herb-medicine residue, the layered structure of the cathode powder is destroyed and converted into Li2CO3, Ni, Co, and MnO. Additionally, selective extraction of lithium is achieved using oxalic acid, and the efficiency and kinetics of lithium extraction are improved under the combined action of herb-medicine residue and oxalic acid.

Summary: This study developed and implemented a self-assessment tool to assist companies in decision-making processes for establishing circular flows based on Lean Manufacturing and Circular Economy principles. The tool utilized a maturity model and was applied to nine companies of varying characteristics. The findings revealed that certain companies showed higher maturity in water-waste and chemical-emissions management, with larger enterprises focusing on these strategies. However, many companies lacked sufficient training and employee awareness prior to seeking cleaner alternatives, and comprehensive actions to manage the product lifecycle were lacking. To address these gaps, the tool provided tailored recommendations for each company to improve their processes, products, and value chain.

Summary: The development of controlled-release fertilizer formulation is important for preventing environmental pollution caused by nutrient leaching and volatilization. This study combined biochar-based fertilizer with encapsulation technology to improve the nutrient release mechanism. Optimal conditions for synthesizing urea-impregnated biochar (UIB) were determined using central composite design, and the release of nitrogen was described by mathematical models. Results showed that encapsulated UIB (EUIB) achieved complete release of nitrogen in water and exhibited improved water retention in sandy-textural soil. Therefore, EUIB derived from peppercorn waste has the potential to be used as a sustainable controlled-release fertilizer for agriculture.
