The potential for magnesium storage batteries to become the next generation of rechargeable batteries is high. This is largely due to the abundance of magnesium metal resources and their high safety and electric capacity per volume. Our research team has been studying magnesium alloys as anode materials for these batteries. Specifically, we have been investigating the electrochemical activity and mechanism of adding copper to Mg-9mass%Al and Mg-9mass%Al-3mass%Ca. Our findings indicate that the electrochemical activity increased with the addition of 1mass%Cu, but decreased with the addition of 3mass%Cu. In addition, changes in lattice constant and basal orientation were also observed. These changes decreased with 1mass%Cu and increased with 3mass%Cu. SEM observations showed that the cell delimitation was indistinct for the 1%Cu addition. © 2024 The Japan Institute of Light Metals.

The search for novel multi-functional material has been on the rise for the past decades. These materials ought to possess flexible structures and tunable properties in order to be utilized for a variety of applications. Perovskite materials are predominantly used in solar cell applications due to their broad absorption spectrum, long carrier lifetime, and long transport distance of electrons and holes. Nevertheless, their unique and tunable properties allow for their utilization in a wide range of applications. In this work, a review on the application of perovskite materials in hydrogen production, supercapacitors, and optoelectronic devices is presented. The role of perovskite in the improvement of said applications is investigated, and future outlook and remarks are presented. This paper highlights the potential utilization of perovskite material outside the scope of photoelectric devices and solar cells. © 2023 IEEE.

Heusler alloys combined with MgO interfaces exhibit interfacial perpendicular magnetic anisotropy, making them attractive forenergy-efficient spintronic technologies. However, finding suitable Heusler/MgO heterostructures with desired properties ischallenging due to the vast range of compositions available and the complexity of interfacial structures, particularly for theemerging quaternary Heusler compounds. In this study, we report a high-throughput screening of quaternary-Heusler/MgOheterostructures for spintronic applications. By analyzing various materials descriptors, including formation energy, convex hulldistance, magnetic ordering, lattice misfit, magnetic anisotropy constant, tunnel magnetoresistance, Curie temperature, and atomicsite disordering, we identified 5 promising compounds out of 27,000 quaternary Heusler compounds. These compounds, namelyIrCrAlTi, IrCrGaTi, IrMnZnTi, OsCrAlTa, and TaGaOsCr, show potential for designing energy-efficient perpendicular magnetic tunneljunctions. This work demonstrates an efficient approach using open quantum materials repositories, effective materials descriptors,and high-throughput computational techniques to accelerate the discovery of quaternary-Heusler-based functional materials.

Thailand has a growing demand in coffee consumption every year. Currently, the nation's capacity for producing coffee is limited, necessitating a significant amount of imports from overseas. The Arabica coffee in the north of Thailand, where the scent and taste of coffee have a distinct identity based on varied cultivation locations, has reasonably good quality. Because of the impact of the environment, it is still challenging to maintain the quality of coffee beans from season to season. Moreover, fierce competition with nearby nations like Laos and Vietnam leads to lower prices of coffee beans. This forces Thai farmers and entrepreneurs to embrace more advanced technologies in order to comprehend the environment of each plantation region and boost their level of competition. This project aims to develop a trustworthy and cost-effective IoT field monitoring solution to assist farmers in understanding the climate conditions in various plantation areas. In order to examine the relationship between the environments, the data collected by the devices can be transferred back to the public cloud server. Then, it can be used as knowledge to raise Thai coffee beans' quality to a premium level so they can continue to compete with coffee beans from other countries. © 2023 IEEE.

Carbon nanotube field effect transistor (CNFET) performance is primarily influenced by a variety of characteristics, such as nanotube diameter, operating voltage, pitch, the number of tubes, dielectric constant, and contact materials. In this study, the dielectric constant and the number of carbon nanotubes (CNTs) were emphasized to analyze the propagation delay and average power dissipation of basic logic gates. Zirconium dioxide (ZrO2), hafnium oxide (HfO2), and silicon dioxide (SiO2) were used as dielectric materials. In this experiment, the Stanford CNFET model was utilized, and variable factors such as the number of CNTs and the dielectric constant (Kox) accumulated on the nanotube gate's surface were diversified. The correlation coefficients of the delay, the average power, and the CNT numbers were also presented. Furthermore, the multi-objective genetic algorithm and the Rmethod were utilized to find the optimal Kox and the number of CNTs for minimizing the average dissipation power and the propagation delay of some logic gates designed with CNFET. For all the gates considered, the optimal number of CNTs is 4 while the dielectric constant is within the ranges of 19 to 24. © 2023 IEEE.

Fluorine-Free Cosolvent Chemistry Empowering Sodium-Sulfurized Polyacrylonitrile Batteries

Advanced Energy materials 2025年第0期

Localized high-concentration electrolytes (LHCE) show great promise for room-temperature sodium-sulfur batteries. However, the majority of diluents in LHCE systems consist of fluorinated ethers, which are not only dense and expensive but also demonstrate poor reductive stability with sodium metal. Herein, a low-density, non-fluorinated ether electrolyte is presented that demonstrates localized high-concentration behavior. This feature is driven by the weak solvating capabilities of 1,2-dimethoxypropane (DMP) and the ultra-weak solvating nature of cyclopentyl methyl ether (CPME). Impressively, the fluorine-free CPME cosolvent acts as a diluent within the electrolyte. Therefore, the electrolyte achieves a tailored solvation structure characterized by anion-rich species, which fosters the development of a resilient inorganic-rich SEI with superior Na-ion transport. Consequently, with a high sulfur-content sulfurized polyacrylonitrile (SPAN, S content > 45% in SPAN) loading of 4.4 mg cm⁻2 (sulfur loading: 2 mg cm⁻2) and a low electrolyte-to-SPAN ratio of 9 µL mg⁻¹ (E/SPAN = 9), the Na-SPAN cell demonstrates remarkable reversibility of 530 mA h gsulfur⁻¹ after 200 cycles at C/5 rate. This performance surpasses the majority of state-of-the-art Na-SPAN ether-based electrolyte systems reported to date. Hence, this work presents a novel approach for designing cost-effective, high-performance electrolytes for stable, practical Na-SPAN batteries. © 2025 Wiley-VCH GmbH.

DAMAGE TOLERANCE OF DOUBLE-DOUBLE LAMINATES 23

DAMAGE TOLERANCE OF DOUBLE-DOUBLE LAMINATES

23rd International Conference on Composite materials, ICCM 2023

Double-double (DD) lay-up is a new configuration strategy for the design of composite laminates, which allows the use of simplified stacking sequences that leads to potential advantages, such as improved manufacturability and design optimization, as compared to traditional quadriaxial laminates (Quad), which are limited to ply angles of 0°, ±45° and 90°. With the double-double concept, through-the-thickness homogenization is facilitated using thinner sub-laminates and, consequently, profile optimization through thickness tapering becomes possible. In this work, damages after impact and after CAI tests of a double-double laminate (+50/0/-50/0)10 and a hard conventional laminate of equivalent in-plane stiffness (03/90/±45/02/±45)2S are compared. According to the data presented, maximum delaminated areas were of the same order of magnitude for the quad and for the DD laminates, under both conditions: after impact and after CAI tests. The results contribute to the understanding of potential benefits of the double-double concept to damage resistance and damage tolerance of composite laminates. © 2023 International Committee on Composite materials.
