In this study, we focus on examining the stability of Al-based inorganic-organic hybrid thin films deposited through the molecular atomic layer deposition (MALD) process in ambient environment. Our observations reveal an initial reduction in material thickness within the first 3 days, followed by a period of stability. XPS analysis is employed to further investigate the chemical alternations in the aged Al-based hybrid thin films, revealing an increase in C=O species as well as overall oxygen content in the material. We also evaluate the effects of atmospheric exposure on the sensitivity of the Al-based hybrid thin films using electron flood exposure. This study aims to enhance the understanding of the stability of a vapor-phase synthesized hybrid thin film system for advanced resist applications. © COPYRIGHT SPIE.

This study synthesizes three sequential steps: pretreatment, acid hydrolysis, and enzyme hydrolysis for bioethanol and hydrochar production from macroalga Gracilaria. The Taguchi method is employed separately in each step to optimize relevant operating factors, aiming to maximize the monosaccharide yield. During pretreatment, environmentally friendly alkaline ionized water is utilized as it does not contain chemical additives. Afterward, microwave-assisted hydrolysis is adopted to enhance the monosaccharide yield of the macroalga for bioenergy production. The results show that the total sugar of Gracilaria undergoing acid hydrolysis alone is 28.72 g‧L−1. The total sugar content after alkaline pretreatment followed by acid hydrolysis is 32.64 g‧L−1, and it increases to 34.76 g‧L−1 after adding enzymes. Meanwhile, the higher heating value of Gracilaria increases from 10.884 MJ‧kg−1 to 12.620 MJ‧kg−1 after undergoing alkaline pretreatment. After the acid and enzyme hydrolysis processes, it increases to 15.164 MJ‧kg−1. The solid biofuel's calorific value increases by 39 % from the three-stage processes. The liquid product combined with Saccharomyces cerevisiae can produce bioethanol, while the produced hydrochar can be used as a solid fuel. This research promotes the development of macroalgal biomass for energy and environmental applications, thereby advancing the circular bioeconomy. © 2024 The Institution of Chemical Engineers

Oxygen redox is considered a new paradigm for increasing the practical capacity and energy density of the layered oxide cathodes for Na-ion batteries. However, severe local structural changes and phase transitions during anionic redox reactions lead to poor electrochemical performance with sluggish ***, we propose a synergy of Li-Cu cations in harnessing the full potential of oxygen redox, through Li displacement and suppressed phase transition in P3-type layered oxide cathode. P3-type Na_(0.7)[Li_(0.1)Cu_(0.2)Mn_(0.7)]O_(2) cathode delivers a large specific capacity of ~212 mA h g^(-1)at 15 mA g^(-1). The discharge capacity is maintained up to ~90% of the initial capacity after 100 cycles, with stable occurrence of the oxygen redox in the high-voltage region. Through advanced experimental analyses and first-principles calculations, it is confirmed that a stepwise redox reaction based on Cu and O ions occurs for the charge-compensation mechanism upon charging. Based on a concrete understanding of the reaction mechanism, the Li displacement by the synergy of Li-Cu cations plays a crucial role in suppressing the structural change of the P3-type layered material under the oxygen redox reaction, and it is expected to be an effective strategy for stabilizing the oxygen redox in the layered oxides of Na-ion batteries.

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.

The high-temperature lead-free solder alloys of Al-95Zn with the modification of the addition of Sn have been investigated. Its proportion is used to adjust the metallographic microstructure, solidified precipitate phase, and liquidus temperature of the solder alloy. The characterization results, such as scanning electron microscope (SEM), energy dispersive spectrometer (EDS), X-ray diffraction (XRD), and differential scanning calorimeter (DSC), will be discussed in this study. The study results show that the Al-Sn-Zn-based alloy has (Zn)+β- Sn+(Al) precipitates when heat-treated at 900°C for 36 h. Its liquidus temperature of Al-95Zn + xSn is between 342-385°C, and increased Sn content will decrease its liquidus temperature. © 2023 Japan Institute of Electronics Packaging.
