Zinc-ion batteries (ZIBs) have garnered significant attention as potential candidates for large-scale energy storage. In recent years, researchers have made notable progress in extending the cycle life of ZIBs. However, another critical factor, calendar aging, also plays a significant role in applying ZIBs practically. The current research achievements and expectations for the practical application of ZIBs highlight the urgent need for an in-depth investigation of their calendar aging. Nevertheless, the stimuli affecting the calendar aging of ZIBs remain unclear. Before conducting a systematic study, it is essential to identify and clarify the stimuli that may influence the calendar aging of ZIBs and understand the interlaced relationships between them. This perspective comprehensively discusses the potential effects of internal stimuli, such as Zn anode passivation, Zn depletion, electrolyte consumption, and cathode dissolution, as well as external stimuli, including the state of charge (SOC), temperature, pressure, and battery packaging, on the calendar aging of ZIBs. Additionally, some promising research methods are proposed to help researchers further understand and improve the calendar aging of ZIBs. © 2025 Elsevier Inc.

THERMODYNAMIC EQUATIONS FOR THE LIQUIDUS OF (A1-UBU)2-YCY(S) WITH Y NEAR ONE AND WITH CONGRUENTLY MELTING END MEMBERS

引用

JOURNAL OF THE ELECTROCHEMICAL SOCIETY 1981年第7期128卷 1595-1600页

A number of equivalent exact and useful approximate equations for the liquidus of with near unity and with congruently melting end members are obtained. These are general in so far as the liquid phase is concerned, except that the forms written for associated solution models of the liquid depend upon the species assumed. The congruent melting of the end members leads to important, usually ignored, links between the thermodynamic properties of the liquid and those of the binary compounds. It is shown that the common assumption that the heat capacity of a binary, end member, compound equals that of its supercooled liquid is generally incorrect and is unnecessary. The results are applied to a number of recent analyses of liquidus surfaces and lines.

COAL SOLUBILITY AND SWELLING .3. A MODEL FOR COAL SWELLING

引用

ENERGY & FUELS 1990年第4期4卷 393-397页

作者： PAINTER, PC GRAF, J COLEMAN, MM Polymer Science Program Department of Materials Science and Engineering The Pennsylvania State University University Park Pennsylvania 16802 United States

In this paper we propose a model for coal swelling based on a process called disinterspersion. This allows a calculation of the “molecular weight” or number of aromatic “clusters” between cross-link points under the assumption that rigid chains swell with little or no change in average conformation up to a limit imposed by the geometry of the network. Sample calculations are presented and suggest that for an Illinois No. 6 coal the “molecular weight” between cross-link points is small. © 1990, American Chemical Society. All rights reserved.

The facile integration and stability of Si-based photoelectrode architectures are the remaining challenges in the photoelectrochemical (PEC) conversion of CO2 to fuels. In this work, the single-atomic-layer graphene is used as a functional bridging layer to integrate both Si photocathodes and photoanodes, which enable the direct electrodeposition of metal-based electrocatalysts (Cu, Ag and InSn alloys) and a semiconductor-based catalyst (NiFe-LDH) on the graphene/Si heterojunction electrodes for PEC CO2 reduction and O2 evolution reaction, respectively. Photoelectrochemical X-ray absorption spectroscopy results show that the electrodeposited catalysts on the graphene layer are active and leads to efficient transport of photogenerated electrons from Si junctions to electrocatalysts. We demonstrate a PEC device with a full-cell configuration consisting of InSn/graphene/Si heterojunction photocathode and NiFe-LDH/graphene/Si heterojunction photoanode, exhibiting a reduced photovoltage of ~1080 mV compared to the electrochemical counterparts. A self-powered overall PEC CO2 reduction with a promising solar-to-fuel conversion efficiency of 3.2% can be obtained by integrating the graphene/Si heterojunction photocathode and photoanode with a Si photovoltaic. By combining the inherent chemical inertness of graphene with its role as an atomic bridging layer, the facile integration of Si photoelectrodes with various catalysts presents a promising platform for stable and efficient solar-to-fuel conversion. © 2025, The Authors.

CRYSTAL-AMORPHOUS INTERPHASES IN BINARY POLYMER BLENDS

MACROMOLECULES 1991年第11期24卷 3466-3468页

作者： RUNT, JP BARRON, CA ZHANG, XF KUMAR, SK Department of Materials Science and Engineering Polymer Science Program The Pennsylvania State University Pennsylvania 16802 University Park United States

An examination is made of several melt miscible polymer blends with the aid of dielectric spectroscopy and differential scanning calorimetry (DSC). These included PEO/PMMA, poly(caprolactone) (PCL)/poly(vinyl chloride) (PVC), and poly(butylene terephthalate (PBT)/polyarylate (PAr). It is the goal of this research to understand if the characteristics of the interphase in all cases examined were similar tho those found fpr the PVDF/PMMA system. It is found that that the unusual spectra obtained for the PCl/PVC blend do not constitute an isolated example and suggest strongly that the fundamental physics underlaying the crystal-amorphous interphase in miscible blends is more complicated that thought before.

Magnesium-degradable implants have excellent mechanical and osteogenic properties for temporary orthopedic use but are underutilized due to insufficient methods to monitor implant osseointegration and tissue healing. This study evaluated the use of circulatory biomarkers to monitor the bilateral implantation of a Mg-alloy in rats’ femurs. A total of 16 biomarkers were measured from plasma samples collected at multiple timepoints up to 90 days post-implantation. Mg-alloy, Ti-alloy, and Sham (noncritical bone defect) groups were followed with computed tomography, histological, and SEM-EDX analysis. The Sham group showed higher DKK1, OPG, VEGF, and KIM-1 levels than implanted groups. The Mg-alloy group had delayed bone regeneration due to gas release but demonstrated active regeneration up to 180 days and superior osseointegration. Elevated IL-10 and reduced FGF23 at day 28 correlated with accelerated implant degradation. These results underline the complex interactions between biomaterials and biological systems in orthopedic applications and show the value of circulating markers to follow-up implantation. © The Author(s) 2025.

Journal of Pharmaceutical sciences 2025年第7期114卷 103797页

As the chiral drug market grows, developing efficient separation methods while ensuring quality has become a key focus for the pharmaceutical industries. Chiral column chromatography is effective but often impractical due to its expense. In our research, we established a cost-effective chiral analysis method for valsartan using ligand-exchange chromatography (LEC), an underutilized yet promising analytical technique with significant potential for further development in pharmaceutical research. This approach allows separation on a non-chiral column by forming complexes with metal ions in the mobile phase. Valsartan, a widely used antihypertensive drug, and its enantiomeric impurity were analyzed through LEC on a C₁₈ column. We optimized the conditions for chiral selectors, copper ions, and pH, achieving a resolution exceeding 2.7. The method, validated per ICH Q2(R1) guidelines for assay and impurity determination, exhibited outstanding linearity (r² > 0.999) and recovery (97.8 %–101.7 %), ensuring a complete separation of the target peak, even after forced degradation. LEC presents a cost-effective alternative for in-house chiral drug analysis, addressing the challenges posed by limited access to chiral columns in countries focused on local generic drug production, and offering a practical solution to the increasing global demand for efficient chiral separation. © 2025 American Pharmacists Association

The cement industry in Indonesia, heavily relies on coal, contributing significantly to greenhouse gas (GHG) emissions. Simultaneously, Java Island generates over 23 million tons of municipal solid waste (MSW) annually, with limited utilization for energy recovery. This study evaluates the feasibility of substituting coal with refuse-derived fuel (RDF) from MSW in Java's cement industry, focusing on environmental, economic, and technical aspects. Scenario analyses indicate that substituting 10%, 20%, and 30% of thermal energy with RDF could divert up to 8.7 million tons of MSW from landfills annually, reducing GHG emissions by up to 2.77 million Gg CO₂-eq. These reductions align with Indonesia's environmental policies and global climate commitments under the Paris Agreement. The economic assessment demonstrates the viability of RDF, with potential annual cost savings of up to $421 million. Beyond addressing coal dependency, RDF adoption supports circular economy practices, reduces landfill reliance, and mitigates environmental pollution. However, challenges such as infrastructure gaps and regulatory barriers require attention. This study provides actionable insights to guide policy formulation, foster industry investment, and facilitate the implementation of RDF-based energy solutions. By bridging waste management and sustainable energy practices, the findings contribute to Indonesia's renewable energy goals, emphasizing the practical applications of RDF for a more sustainable future in industrial operations. © 2025 The Authors

RECENT ADVANCES IN INTERPENETRATING POLYMER NETWORKS

引用

POLYMER engineering AND science 1985年第9期25卷 517-520页

作者： SPERLING, LH Polymer Science and Engineering Program Department of Chemical Engineering Materials Research Center #32 Lehigh University Bethlehem Pennyslvania 18015

AbstractInterpenetrating polymer networks (IPN\'s) can be defined as a combination of two polymers in network form, at least one of which was synthesized and/or crosslinked in the immediate presence of the other. Historically, the science of IPN\'s began with the papers of J. R. Millar in 1960 on homo‐IPN\'s made from polystyrene, but the first recorded publication is a patent by J. W. Aylsworth in 1914. This latter system was based on phenol‐formaldehyde for one network, and sulfur cured natural rubber for the other network. Early academic laboratories interested in IPN\'s include the Frisch team at Detroit and SUNY, who soon added their former student, Danny Klempner, and Yuri Lipatov\'s team at the Ukranian SSR Academy of sciences in the USSR, as well as the author\'s laboratory. More recent academic teams interested in IPN\'s include Douglas Hourston at the University of Lancaster, England; Robert Cohen at MIT; S. C. Kim at the Korea Advanced Institute of science and Technology, Seoul, Korea; G. Meyer and J. M. Widmaier in Strasbourg, France; and many others. Numerous industrial laboratories are interested, noting that about 90 U.S. patients have been granted, most of them in the past ten years. Systems of special interest include the new thermoplastic IPN\'s, which are really hybrid materials between polymer blends and IPN\'s, and the IPN‐based RIM (reaction injection molding) materials. Other materials include the sequential IPN\'s and the SIN\'s, which have both polymers simultaneously polymerized, and the latex IPN\'s, which often exhibit core‐shell characte
