In this article, we harnessed biomedical applications in laser-assisted etching long-period fiber gratings (LLPFGs) sensors, subsequently deploying them within the realm of biomedical applications. The primary aim of this study was to devise a sensitive method for the detection of antigen-antibodies associated with rheumatoid arthritis (RA) using LLPFGs. Sensing the antigen binding took place on the surface of the optical fiber through a self-assembling process. Given the inherent limitations of conventional rheumatoid factor (RF) testing in terms of specificity, we introduced an innovative serum-based approach geared toward the identification of anti-cyclic citrullinated peptide (Anti-CCP) antibodies. This method exhibited an impressive diagnostic accuracy rate of approximately 80% for RA cases, coupled with an exceptional specificity level of 98% for individuals without RA. The incorporation of LLPFGs in the detection of RA antigen-antibodies presents a highly promising avenue for enhancing the precision and reliability of RA diagnosis. Furthermore, this research aligns closely with the United Nations Sustainable Development Goal (SDG)3, which strives to promote well-being across all age groups and advance sustainable development by addressing health-related challenges, including the accurate diagnosis of diseases like RA. © 2023 IEEE.

MagnesiumMagnesium’s remarkable stiffnessStiffness-to-weight and high strengthStrength-to-weight ratios could enable substantial vehicle lightweighting versus aluminum and steel. However, primary production is very energy- and emissions-intensive, and recyclingRecycling cannot cost-effectively produce magnesiumMagnesium of sufficient purity for die casting and other structural applications. Distillation can produce high-purity magnesiumMagnesium but is capital- and energy-intensive. Gravity-Driven Multiple Effect Thermal System (G-METS) is a continuous low-pressure magnesiumMagnesium distillation process used in primary production or recyclingRecycling in which heat re-use leads to just 0.5–1 kWh energy consumption per kgMg Mg product—which is 80–90% less energy than current Mg distillation. This paper presents new partial distillation experiments showing 99.96% product purity. An industrial distiller design can help to estimate capital costs. New modeling work describes temperature and pressure change in the vapor conduit, energy use and losses in the industrial distiller, and effects of evaporator flow vanes on the separation of volatile elements such as zinc. © The Minerals, Metals & materials Society 2025.

Significant grain refinement, precipitate redistribution, and increase in microhardness by 25% were achieved in processed regions compared to base material. CorrosionCorrosion testing in 0.9% NaCl solution revealed that the FSP-treated material exhibited a 196% lower Icorr and a more stable open circuit potential (OCP) than cast WE43WE43, suggesting superior corrosion resistanceCorrosion resistance. While the findings promise suitability of the processed alloy for a more intensive range of operating conditions than the cast alloy, further work to study the effect of the size, volume, and composition of the oxide reinforcements needs to be carried out. © The Minerals, Metals & materials Society 2025.

The majority of Ethiopia's population, primarily women, is susceptible to smoke inhalation during cooking, and they spend the majority of their time striving to collect firewood. Biomass deforestation for cooking harms the rural household economy and contributes to national and global environmental change, such as pollution and health issues. The effort should aim to integrate the Scheffler concentrator with a thermal storage system via the secondary solar cooking reflector in order to stimulate indoor cooking while avoiding concerns associated by carbon inhalation and deforestation. As a result, the Injera bakery system powered by solar thermal energy is born. There is a primary (Scheffler), secondary (reflective), and thermal storage device incorporated, as well as a cooking (pan) mounts. Solid works software was utilized for Scheffler focus and secondary reflector modeling and simulation. The thermal retention capacity of a storage device is determined using heating and cooling curves generated by software modeling and simulation. The findings gained would aid in the development of any comfortable indoor cooking system specifically for rural areas without a grid connection, and as a result of this study, carbon inhalation and deforestation difficulties would be mitigated. Through automation, the output rate would also increase the amount and efficiency of injera. This analysis focuses on the Injera baker concept for domestic applications. © 2021

Effect of Surface Roughness on the Magnetism, Nano-indentation, Surface Energy, and Electrical Properties of Co60Fe20Dy20 Films on Si (100) Substrate

Journal of Electronic materials 2024年第4期53卷 1752-1762页

作者： Liu, Wen-Jen Chang, Yung-Huang Chiang, Chia-Chin Chen, Yuan-Tsung Lin, Chih-Chien Chen, Pei-Ling Lin, Shih-Hung Department of Materials Science and Engineering I-Shou University Kaohsiung840 Taiwan Bachelor Program in Industrial Technology National Yunlin University of Science and Technology 123 University Road Section 3 Yunlin Douliou64002 Taiwan Department of Mechanical Engineering National Kaohsiung University of Science and Technology Kaohsiung City80778 Taiwan Graduate School of Materials Science National Yunlin University of Science and Technology 123 University Road Section 3 Yunlin Douliou64002 Taiwan Department of Electronic Engineering National Yunlin University of Science and Technology 123 University Road Section 3 Yunlin Douliou64002 Taiwan

In this study, we focused on depositing a target material, cobalt-iron-dysprosium (Co60Fe20Dy20), onto silicon (Si) (100) substrates with thickness varying from 10 nm to 50 nm through a direct-current (DC) magnetron sputtering technique. The subsequent step involved subjecting the samples to an hour-long annealing process in a vacuum annealing furnace at temperatures of 100°C, 200°C, and 300°C. To assess the elemental composition of the CoFeDy films, energy-dispersive X-ray spectroscopy (EDS) was employed. An observed trend indicated an increase in low-frequency alternating-current magnetic susceptibility (χac) with the increasing thickness. Remarkably, the CoFeDy films exhibited their peak χac following annealing at 300°C, with an optimal resonance frequency of 50 Hz. After annealing at 300°C, the CoFeDy film’s surface energy peaked at 50 nm. The magnetic, electrical, and adhesive properties of the CoFeDy films were notably influenced by surface roughness at different annealing temperatures. Atomic force microscopy (AFM) analysis revealed a gradual reduction in film roughness post-annealing, corresponding to smoother surfaces indicative of a weaker domain wall pinning effect, heightened carrier conductivity, and increased liquid spreading. Collectively, these outcomes contributed to diminished χac, reduced electrical resistance, and enhanced adhesion.
