Supply chain risk management involves an effort to establish collaboration among partners to develop a shared risk management process to deal with risks and uncertainties resulting from logistic activities and distribution of resources. Risk management in healthcare supply chains involves the identification of the risk of quality and information failure in delivering healthcare services. In recent times, the challenges of healthcare supply chains include the management of risks along with maintenance of the ecological balance of natural environments. Thus, mitigating the impact of supply chain disruptions and healthcare waste is a crucial need. The implementation of circular economy (CE) in healthcare supply chains can result in eliminating waste using eco-friendly materials, optimization of resource yields, and circulation of products at their highest value. The purpose of this study is to minimize the risk impact if the supply of the critical product is delayed or unavailable when needed and using sustainable approach with CE implementation to mitigate the risks. To fulfil the research objectives, the risk analysis, evaluation, assessment, and mitigation, as well as the CE strategy for establishing sustainable supply chains, are demonstrated. A qualitative case study is being undertaken at the primary care level, an upstream healthcare service provider. Primary care is crucial for health-care delivery. The risk matrix was built by considering the mean time to arrival for the critical product. Data was gathered through interviews with practitioners such as doctors, operational employees, and logistic department managers. This research used Failure Mode Effect and Critical Analysis (FMECA) to prioritize risks and minimize the risk of failure within healthcare supply chains. The results show that the highest Risk Priority Number (RPN) is associated with delays or shortages of critical products such as latex gloves, often due to import delays. To address this issue in

Wetting mechanism of molten 2N(99 %)-, 5N(99.999 %)-purity aluminum and Al-12.6 %Si alloy on silicon nitride (Si3N4) substrate was investigated by conducting high-temperature wettability tests with a sessile drop method and extrusion method. From the results of the sessile drop experiment, it was found that oxide films on the surface of aluminum (alloy) droplet disappear at 1300-1400 C, and then their wettability was improved with wetting angles of 37-44. The formation of aluminum nitride (AlN) reaction layers between aluminum droplet and Si3N4 substrate and the dissolution of Si from Si3N4 substrate into the droplet were also responsible for the improved wettability because wetting angles of molten aluminum are much smaller on AlN than on Si3N4, and surface tension between molten aluminum and the surrounding atmosphere is decreased with increasing the amount of dissolved Si, respectively. From the results of the extrusion experiment, on the other hand, oxide film formed after extrusion of droplet was found to move upwards by convection flow, resulting in the improved wettability even at lower temperatures of 1100-1300 C. Therefore, the formation and removal of oxide film could be controlled by optimizing temperatures and oxygen pressure during aluminum brazing. © 2023 28th IFHTSE 2023 Congress. All rights reserved.

A Novel Methodology to Estimate the Athermal Contribution During Electric-Assisted Deformation of AA 1050 Alloy

Metallurgical and materials Transactions A 2025年 1-8页

In this research, electroplastic test with and without stress relaxation is utilized to decouple the rate-dependent component of stress drop. The stress relaxation exhausts the effect of rate-dependent component by dislocation overcoming the short-range obstacle. The net contribution due to electric current after stress relaxation is rate-independent or athermal. No additional assumptions are included to derive the athermal component. The methodology is successfully demonstrated through electric-assisted deformation tests using AA1050 alloy samples.

Although landfills damage the environment due to over-exploitation of land resources, several countries still depend on this waste management strategy. To reduce this dependency, several countries have begun to increase the level of waste recycling due to regulations pressure from regional governments (e.g., European Union). There are also initiatives from individuals or organizations to create a more circular waste management business, which seeks to extend the product life cycle from waste recycling, reuse and reduction, has been developed. This research attempts to map the interrelationship between government policy and circular waste management (CWM) business initiatives from individuals or organizations. Using a System Dynamic (SD) approach, this research produces qualitative and quantitative model to explain the interrelationship. From the SD model simulation, the results show that the decrease in the amount of waste sent to landfills is affected by the population size and the level of waste production per capita. While qualitatively, the model shows that capacity building both in quality and quantity and waste segregation campaigns for the community are important in growing the CWM business in the future. © 2023 IEEE.

In this study, we present a method to enhance the sensitivity of fluorinated EUV resists by leveraging the rapid coupling reaction between electrophilic carbon radicals and electron-rich alkenes. To validate the impact of the vinyl groups, DVS-HNF was synthesized by introducing fluorinated alkyl chains and silyl vinyl functional groups into the model compound. Additionally, TMS-HNF and EDMS-HNF, which do not contain a vinyl moiety, were synthesized for comparison. To evaluate the patterning properties of the three materials, e-beam lithography experiments were conducted, resulting in the formation of negative-tone patterns for all three materials. Comparing sensitivities, DVS-HNF with two vinyl moieties exhibited the most excellent sensitivity, confirming the effective collaboration between fluorinated alkyl radicals and vinyl groups. After performing an EUV lithography experiment on DVS-HNF, it was confirmed that a 30 nm negative-tone pattern was successfully formed with excellent sensitivity. These results substantiate the potential of the single-component molecular resist for high performance EUV lithography. © COPYRIGHT SPIE.
