Authors: Han Songyi , Choi Young Kuk , Kim Jeoung-Kyu , Lee Wang-Geun 
Published: December 2024

Secondary batteries, unlike primary batteries, have experienced rapid growth as batteries that can be recharged and reused after discharge, such as those used in electric vehicles. As the market grows, the increasing prices of rare metals such as lithium, cobalt, and nickel, which are key raw materials for lithium secondary batteries, are putting significant pressure on battery manufacturers and automobile manufacturers. Sodium, the fourth most abundant element on Earth, is gaining attention for its potential to increase price competitiveness and enable the recycling of materials without emitting carbon dioxide in sodium-ion batteries. In this study, we fabricated secondary battery electrodes composed of metal-carbon using a composite anode material consisting of tin and hard carbon, and evaluated the electrochemical properties of these electrodes. The metal-hard carbon composite material exhibited a high discharge capacity of 559.6 mAh/g and an initial Coulombic efficiency of 90.74% after one cycle. Compared to electrodes using only hard carbon, the discharge capacity increased by approximately 200%, while maintaining a Coulombic efficiency of 90% without degradation. Even after 100 cycles of charging and discharging at a current density of 0.4 mA/cm², the long life performance of maintaining 90% or more of C.R. compared to the initial stage was stably operated. Also, Hard carbon has a volume capacity of 1.5mAh/cm², but Metal-hard carbon composite material has a volume capacity of 2.1~2.4mAh/cm², hence increasing the energy density of the sodium battery. The metal-hard carbon composite material produced in this study is considered suitable for application as a sodium battery anode material due to its excellent Coulombic efficiency, high capacity characteristics, and outstanding long-term stability.

Verifying the Effect of Organic Additives in Aqueous Zinc Batteries Via Operando Imaging Technology
Authors: Lee Sungmin , Huh Sung-Ho , Yu Seung-Ho 
Published: December 2024

Aqueous zinc batteries (AZBs) have emerged as an alternative of lithium-ion batteries (LIBs) due to their potential for high energy density, safety, and cost-effectiveness. However, the long-term stability of zinc metal anode has been hindered by hydrogen evolution reaction (HER), dendrite growth, and byproduct formation (Zn4(OH)6SO4·xH2O, zinc basic sulfate). To stabilize the zinc metal anode, various strategies such as surface coating and electrolyte design have been studied. In particular, electrolyte additives are regarded as practical strategies owing to low cost and simple methods.
To improve the stability of zinc metal anode, organic additive was introduced. During the plating/stripping process, the enormous dendrites were observed in blank electrolyte via side-view operando X-ray imaging. Furthermore, a number of H2 bubbles were generated at the electrode surface. On the contrary, when the organic additive was added into electrolyte, the smooth surface with homogeneous deposition was confirmed and the formation of hydrogen gas was rarely observed. In addition, the uniform Zn deposition with organic additive was also verified through top-view operando optical imaging, whereas the black spots were formed on the surface without the additive, which represent the Zn dendrite formation. Based on the superior stability, the Zn||Cu half-cell with the organic additive maintained the steady voltage profile over 1600 h at 1 mA cm-2, while the short circuit occurred after 100 h without the additive.

Fluoride-Free Sonochemical Exfoliation of Titanium Aluminium Carbide to Few-Layered Titanium Carbide Nanosheets
Authors: Meichandiran Balasubramaniam , Kennedy Tadhg 
Published: December 2024

Two-dimensional (2D) transition metal carbides and carbonitrides, also known as MXenes, possess a unique blend of hydrophilic surfaces and excellent electrical conductivity,[1] characteristics seldom found in other 2D nanostructures like graphene and transition metal dichalcogenides. Particularly, titanium carbide (Ti3C2Tx) and its composites have garnered increasing attention across diversified fields such as catalysis,[2] energy conversion and storage,[3] membrane separation,[4] photothermal conversion,[5] and field-effect transistors.[6]

Thus far, chemical etching of aluminium (Al) layers from titanium aluminium carbide (Ti3AlC2) remains the predominant method to synthesize Ti3C2Tx.[7] However, fluoride-based synthetic procedures remain a hindrance to the practical applications of these promising materials. Despite the identification of various etching conditions, current state-of-the-art strategies involve handling hazardous hydrofluoric acid or fluoride-based compounds such as LiF/HCl, NaHF2, KHF2 and NH4HF2, resulting in highly toxic liquid waste and surface functionalization of Ti3C2Tx with fluorine and oxygen-containing terminations.[8] Achieving selective removal of Al layers while preserving the 2D structure of Ti3C2Tx necessitates careful design of electrolytes.
Hence, in this work, we present an efficient, fluoride-free sonochemical approach for the etching and delamination of Ti3AlC2 using aqueous tetramethylammonium hydroxide (TMAOH) solution. During the sonochemical exfoliation, ultrasound waves facilitate penetration of solvent ions through Ti3AlC2 to selectively etch out Al, forming few-layered Ti3C2Tx nanosheets. In this particular study, the effect of sonication time and effect of TMAOH concentration is explored.

Sustainable Production and Application of Heterosite FePO4 As a Positive Electrode for Sodium Secondary Batteries
Authors: Nozaki Fumiyasu , Hwang Jinkwang , Matsumoto Kazuhiko 
Published: December 2024

To address the growing societal need for environmentally friendly and cost-effective secondary batteries, sodium secondary batteries are emerging as a promising solution. This is attributed to the abundance and widespread distribution of sodium resources, which makes them highly attractive for sustainable energy storage applications.1

Triphylite NaFePO4 is one of the promising positive electrode materials for sodium ion batteries (SIBs) because of its structural stability with polyanionic structure, relatively high theoretical capacity, and abundance of constituting elements. Despite this, the direct synthesis of triphylite NaFePO4 is challenging because of its thermodynamic metastability. Hence, it is generally produced from triphylite LiFePO4, the analogous structure to triphylite NaFePO4.2 Our group reported a chemical delithiation method using Cl2 to prepare heterosite FePO4 from triphylite LiFePO4.3

In this study, we report a sustainable routine to prepare heterosite FePO4 from triphylite LiFePO4 via the chemical delithiation using O2 in acetic acid aqueous solution. At the same time, the lithium source is recovered as lithium acetate (CH3COOLi) during the delithiation process, and LiFePO4 is then resynthesized from the recovered lithium acetate using the solid-state method. This approach enables a closed-loop lithium recovery system and makes the production of heterosite FePO4 more cost-effective. Moreover, the electrochemical performances of the heterosite FePO4 positive electrode are investigated for SIBs.

Authors: Rakhman Damira , Konarov Aishuak , Bakenov Zhumabay 
Published: December 2024

The limitations of lithium-ion battery systems, including lithium scarcity, demanding assembly conditions, and safety risks associated with flammable organic electrolytes, underscore the need for renewable, cost-effective, and safe alternatives. While zinc-ion or hybrid aqueous battery systems have garnered interest, challenges such as undesired side reactions, limited electrochemical stability, and electrolyte leakage persist, hindering large-scale adoption. Among electrolyte engineering approaches, hydrogel electrolytes have emerged as promising solutions, offering improved stability and relatively high ionic conductivity while mitigating leakage risks. Additionally, the modification opportunities of the hydrogel electrolytes present great potential for various applications.
Here, we synthesized a dual-function hydrogel electrolyte based on polyacrylamide and poly(ethylene dioxythiophene):polystyrene. This electrolyte effectively reduces water content and enhances stability by minimizing undesired side reactions. Moreover, the polymer network and its functional groups promote controlled ion transport. Swelling in a binary solution of ethylene glycol and water (EG 10%) further enhances the stability of the assembled battery system. The developed hydrogel exhibits relatively good ionic conductivity (1.6 * 10-3 S cm-1) and excellent electrochemical stability, surpassing 2.5 V on linear sweep voltammetry tests (Figure 1). An assembled aqueous lithium-ion hybrid battery with a zinc anode demonstrates high capacity (119.2 mAh g-1), close to 100% columbic efficiency, and good cycle stability, retaining 67.6% capacity after more than 380 cycles. This study highlights the potential of polyacrylamide-based hydrogel electrolytes with dual functionality as the electrolyte and separator, inspiring further development in hydrogel electrolytes for aqueous battery systems.

Challenges on Developing Room-Temperature Rechargeable Magnesium Batteries with Oxide Cathodes
Authors: Ichitsubo Tetsu , Li Hongyi , Shimokawa Kohei , Ye Xiatong 
Published: December 2024

Constructing sustainable energy systems requires rechargeable batteries with high safety, long cycle life and low production costs. Rechargeable magnesium batteries (RMBs) have been expected to be a promising candidate owing to low resource constraints compared to the commercial Li-based batteries. However, the development of RMBs have been stagnated after the first report of a prototype system, which consists of a Chevrel phase cathode, Mo6S8, and a Cl-based electrolyte.[1] The development of high potential oxide cathodes and non-corrosion Cl-free electrolyte encounters significant difficulties. Specifically, for oxide cathodes, the strong Coulomb interaction between Mg2+ and host structures usually inhibits the solid-state diffusion, causing a significant low discharge capacity compared to the theoretical value and rapid capacity loss during cycling.[2] Besides, non-corrosion electrolytes usually passivate Mg metal anodes and/or induce side reactions on oxide cathodes,[3] where remarkably decreases the cell voltage and accelerates the decomposition of electrolytes and active materials.
In this presentation, we introduce our efforts to construct room-temperature RMBs with oxide cathodes and Cl-free electrolytes combining both the experimental and computational approaches. To explore suitable host structures for the topotactic Mg2+ intercalation, we revealed the phase transformation pathways and evaluated cathode properties of various transition oxide cathodes (e.g. MnO2 polymorphs) at both elevated temperature (150℃) and room temperature.[3-6] Moreover, to assess the electrolyte compatibility, we discovered the connection between the solvation environment and the reaction behavior on both the oxide cathodes and Mg metal anodes.[3,7] These findings pave the way for room-temperature RMBs using oxide cathodes.

Published: December 2024

Background: Employer requirements play a fundamental role in the successful delivery of any building construction project. These requirements serve as essential inputs for the design and specification of the project to be constructed. However, recurring changes in these requirements often lead to project delays and budget overruns. Thus, this study aims to investigate the root causes and impacts of recurring changes in employer’s requirements in public building construction projects.Methods: Employing a descriptive research design, for this study the data collected through questionnaires from various construction stakeholders. The study population comprised ongoing public building construction projects in Jimma Town, Ethiopia. Purposive sampling was employed to select participants. The data were analyzed using Microsoft Excel, Statistical Package for Social Science (SPSS) 25, and R statistical software. Descriptive statistics were utilized to calculate frequencies, percentages, and rankings of variables based on mean values.Results: Through mean value analysis, the top 10 causes of requirement changes identified and ranked encompassing as: lack of careful checking and correcting planning documents; ineffective risk management, planning, and monitoring structures; poor project management and planning skills; and inadequate preconstruction study and review of design documents. Furthermore, this study assessed the impacts of requirement changes, highlighting increase the cost of the project, claim, and dispute between contracting parties and delay in completion/delivery as the most significant outcomes. The findings of this research offer valuable insights for project managers and stakeholders, enabling them to enhance requirement management practices in building construction projects. By mitigating the identified causes and impacts, construction professionals can effectively manage changes in employer requirements. The efficient management of requirement changes is essential for the successful delivery of sustainable and resilient infrastructure (SRI) projects, aligning with the broader goals of sustainability, cost‐effectiveness, stakeholder satisfaction, and long‐term resilience.

Published: December 2024

Background: Chronic kidney disease (CKD) is a global public health concern, affecting approximately 850 million people worldwide. Guidelines recommend early identification and management of CKD to mitigate disease progression and delay the onset of complications. Recording a CKD diagnosis in medical records is associated with improved kidney function and blood pressure monitoring, better use of disease‐modifying therapy, and reduced risk of CKD progression. REVEAL‐CKD is a multinational, observational study that aims to estimate the prevalence of stage 3 CKD which is unrecorded in administrative databases.Methods: Data were extracted from country‐specific databases of patient medical records in Australia, Brazil, Canada, England, and Spain. Included patients (aged ≥ 18 years) had two consecutive estimated glomerular filtration rate (eGFR) measurements between 30 and < 60 mL/min/1.73 m2 taken 91–730 days apart. Patients were considered to have unrecorded CKD if they had no CKD diagnosis code (any stage) at any time before and up to 6 months after study index (date of second qualifying eGFR).Results: Across countries, median age was 72–78 years, median eGFR was 46.5–53.5 mL/min/1.73 m2, and availability of urinary albumin—creatinine ratio testing ranged from 4.9% (Brazil) to 53.5% (Canada). The prevalence of unrecorded stage 3 CKD was 90.0% (1002/1113 patients) in Australia, 97.0% (10,925/11,262) in Brazil, 92.0% (42,226/45,914) in Canada, 56.9% (84,237/148,153 in England, and 84.8% (27,035/31,866) in Spain.Conclusions: More than half of the patients with laboratory evidence of stage 3 CKD lacked a CKD diagnosis code in all countries examined. Substantial intercountry variations in rates of CKD recording and testing were observed. International sharing of best practice guidance, systematic changes to improve data quality, and increased awareness of the importance of timely coding among healthcare professionals will help to improve accurate recording of stage 3 CKD.Trial Registration: ClinicalTrials.gov identifier: NCT04847531.

Published: December 2024

Introduction: Ruptured abdominal aortic aneurysm (RAAA) is a very severe condition with 17.4%–45.1% 30‐day mortality rates. The 30‐day death prediction model for patients with RAAA is one of the most significant models developed by Harborview Medical Center (HMC). The Harborview Risk Score (HRS) was calculated using the following four preoperative factors: minimum systolic blood pressure, age, Pondus Hydrogenii (pH), and creatinine (Cr). The objective was to evaluate the validity and dependability of the HMC model for predicting 30‐day mortality with a large data sample.Methods: The medical subject heading (MeSH) was used to search the electronic database. Four key indicators, the 30‐day mortality rate, and the HRS score were among the data that were retrieved. The inclusion criteria include RAAA patients, applying the HMC prediction model and with baseline data, and the exclusion criteria include other prediction models and studies with incomplete baseline data from patients.Results: There were 2931 participants in total throughout 7 trials; 1536 of these patients came from the National Surgical Quality Improvement Program (NSQIP) database, and the other patients came from single center in each project. Thirty‐day mortality was 34.9% (95% CI: 0.27–0.33) on average. The majority of the patients (n = 2616, 89.25%) had an HRS score of 0–2. All patients who had a score of 4 died, no matter which single center they were in. Furthermore, with every extra point that a patient with a score of 0–3 received, their death rate rose by around 15%–20%.Conclusion: The HMC prediction model is a trustworthy prediction model that can more simply and accurately predict 30‐day postoperative mortality through the use of age, pH, Cr, and minimum systolic blood pressure. It also provides more preoperative counsel and assessment to the patient, family, and physician.

Abstract
Evolutionarily conserved selenoprotein O (SELENOO) catalyzes a post-translational protein modification known as AMPylation that is essential for the oxidative stress response in bacteria and yeast. Given that oxidative stress experienced in the blood limits survival of metastasizing melanoma cells, SELENOO might be able to impact metastatic potential. However, further work is needed to elucidate the substrates and functional relevance of the mammalian homologue of SELENOO. Here, we revealed that SELENOO promotes cancer metastasis and identified substrates of SELENOO in mammalian mitochondria. In patients with melanoma, high SELENOO expression was correlated with metastasis and poor overall survival. In a murine model of spontaneous melanoma metastasis, SELENOO deficiency significantly reduced metastasis to distant visceral organs, which could be rescued by treatment with the antioxidant N-acetylcysteine. Mechanistically, SELENOO AMPylated multiple mitochondrial substrates, including succinate dehydrogenase subunit A, one of the four key subunits of mitochondrial complex II. Consistently, SELENOO-deficient cells featured increased mitochondrial complex II activity. Together, these findings demonstrate that SELENOO deficiency limits melanoma metastasis by modulating mitochondrial function and oxidative stress.

Published: December 2024

Abstract
Resistance of BRAF-mutant melanomas to targeted therapy arises from the ability of cells to enter a persister state, evade treatment with relative dormancy, and repopulate the tumor when reactivated. A better understanding of the temporal dynamics and specific pathways leading into and out of the persister state is needed to identify strategies to prevent treatment failure. Using spatial transcriptomics in patient-derived xenograft models, we captured clonal lineage evolution during treatment. The persister state showed increased oxidative phosphorylation, decreased proliferation, and increased invasive capacity, with central-to-peripheral gradients. Phylogenetic tracing identified intrinsic and acquired resistance mechanisms (e.g., dual specific phosphatases, reticulon-4, and CDK2) and suggested specific temporal windows of potential therapeutic susceptibility. Deep learning-enabled analysis of histopathological slides revealed morphological features correlating with specific cell states, demonstrating that juxtaposition of transcriptomics and histological data enabled identification of phenotypically distinct populations from using imaging data alone. In summary, this study defined state change and lineage selection during melanoma treatment with spatiotemporal resolution, elucidating how choice and timing of therapeutic agents will impact the ability to eradicate resistant clones.
