ABSTRACTThe wide use of poly(propylene carbonate) (PPC), a biodegradable polymer made from carbon dioxide, will contribute greatly to alleviating environmental issues such as white pollution and greenhouse effect. However, the poor mechanical properties and low glass transition temperature (Tg) seriously limit the practical application of PPC. Traditional reinforcement methods for PPC will reduce the toughness sharply. Herein, we propose a new strategy for preparing strong and tough PPC through in situ generated high‐performance PPC‐based cross‐linked microdomains (PPC‐MD). Specifically, based on the aminolysis reaction between carbonate groups in PPC and multiple amine groups in polyethylenimine, PPC‐MD and hydroxy‐terminated PPC with low molecular weight (l‐PPC‐OH) are generated during melt blending. Then, hexamethylene diisocyanate is added to link l‐PPC‐OH for the purpose of eliminating the plasticization of l‐PPC‐OH and the degradation effect of terminal hydroxyl group. The PPC‐MD with high Tg can effectively reinforce PPC and improve its toughness. The PPC/PEI/HDI‐0.02/0.04 shows a high tensile strength of 29.4 ± 2.5 MPa and a toughness of 86.8 ± 5.2 MJ/m3, which is 2.58‐ and 1.38‐folds of PPC, respectively. Besides, the PPC‐MD can greatly improve the Tg of PPC as well. It is worth highlighting that this method can be accomplished by melt blending, which is facile and can be scaled up. We envision that this work will enrich the modification method of PPC and promote the practical application of PPC as the as‐fabricated PPC shows integrated high strength, high toughness, and high Tg.

AbstractIncorporation of shape memory polymers into biomedical devices is an attractive option due to their notable advantages of low cost, biocompatibility, tunable degradability, patient‐specific design and adjustable mechanical and thermal properties. Shape memory polyurethanes are particularly attractive due to their extensive temperature range for shape recovery as well as the ability to fine‐tune the glass transition temperature. This study aimed to synthesize a shape memory polyurethane using glycerol as chain extender with a glass transition temperature within a suitable temperature range for biomedical applications. The results showed that the triggering temperatures for the synthesized samples change between 63.95 °C and 88.21 °C. Shape memory properties were investigated for the temperature range 40–75 °C. Shape recovery times were found to be substantial with increasing temperature with ~102 s at 40 °C and ~1 s at 75 °C. Shape fixity and shape recovery rates for the same temperature ranges were 77.8% and 85.6% at 40 °C and 100% and 100% for 75 °C. The cytotoxicity assay indicates promising biocompatibility of the synthesized material for biomedical purposes. Overall, the synthesized polymers were found to be a potential candidate for biomedical applications such as stents, aneurysm filling or occlusion devices. © 2024 Society of Chemical Industry.
Reprocessable and Chemically Recyclable Polyester Elastomers via a Tandem Ring‐Opening Polymerization and Photo‐Crosslinking Strategy From Bio‐Renewable β‐Methyl‐δ‐Valerolactone

Published: November 2024

ABSTRACTDue to the lack of effective physical reprocessing or chemical recovery capabilities, thermosetting polymers face long‐term post‐disposing problems. The introduction of dynamic covalent bonds can effectively combine reprocessing ability with typical robust properties of thermosetting polymer. However, after multiple reprocessing treatments, thermosets often suffer significant decrease in mechanical properties, so the chemical recycling and reuse is crucial and necessary for the sustainable development of thermosetting polymers. Herein, a series of polyesters PβMδVL‐TA with mono‐ or bis‐terminal cyclic disulfide bond was first synthesized via esterification between terminal hydroxyl of PβMδVL and carboxyl of thioctic acid (TA). Then, the thermosetting elastomer with both physical reprocessability and chemical recyclability was prepared by simple UV‐triggered ring‐opening polymerization of cyclic disulfide. By regulating cross‐linking sites and the molecular weight of the mono‐ or bis‐PβMδVL‐TA, such polyester elastomers exhibit good tensile strength and elasticity with elastic recovery can reach 98% after 10 cycles. Furthermore, the dynamic reaction of disulfide bonds induced by hot pressing and UV light enables multiple reprocessing of cross‐linked elastomers. Remarkably, the efficient chemical recycling of the elastomers was achieved to recover pristine βMδVL monomer with 90% yield in the presence of ZnCl2 as the catalyst at 130°C.

ABSTRACTPurposeThe hippocampus has long been associated with cognition and memory function, the implications of lysine lactylation (Kla), a recently identified post‐translational modification (PTM), in the role of the hippocampus remain largely unexplored.Experimental DesignAn LC‐MS/MS bottom‐up proteomics analysis of three human hippocampal tissue samples was applied to profile the lactylation map in human hippocampi under normal physiological conditions.ResultsWe identified 2579 quantifiable Class I lactylated sites in 853 proteins, of which contained four types of modification motifs. Cellular localization analysis implies that a majority of lactylated proteins were distributed in the cytoplasm. Functional enrichment analysis showed that lactylated proteins were mainly involved in energy metabolic pathways. In addition, we found that the lactylation on histones exhibits a certain degree of conservation across different tissues. Compared with previously reported lactylation databases, 213 lactylated proteins were identified for the first time in this study.Conclusion and Clinical RelevanceThe first global lactylated proteins atlas of human hippocampi was reported in this study. Our work provides a reliable foundation for further research on lactylation in the hippocampus under physiological conditions.

Published: November 2024

AbstractPotassium‐ion batteries (PIBs) using carbonaceous anode materials have attracted a great deal of research interest. However, the large atomic size of potassium ions inevitably leads to huge volume expansion and the collapse of anodes during intercalation, which greatly hinders rate performance and cycling life. In this work, carbon nanotube‐derived porous N‐doped carbon nanoribbon (CNR) bundles are designed as an anode for PIBs. These CNR materials are in rich defects which provide fast channels for charge transport and abundant active sites for potassium ion storage. The CNR materials exhibit a maximum capacity of 441.4 mA h g−1 at a current density of 0.2 A g−1 after 200 cycles as well as a highly reversible capacity of 263.6 mA h g−1 at a current density of 5.0 A g−1 even after 1000 cycles. This work provides guidance for the structure design of nanoribbon materials for high‐performance PIBs.

Published: November 2024

AbstractAqueous ammonium‐ion batteries (AAIBs) are promising candidates for next‐generation energy storage devices. However, organic materials as suitable anodes face severe challenges due to their structural instability and poor conductivity, which hinder the development of AAIBs. Herein, an innovative approach is introduced by incorporating an organic benzoquinone framework, 5,7,11,14‐tetraaza‐6,13‐pentacenequinone (TAPQ), with reduced graphene oxide (rGO) using a solvent exchange method. Benefiting from π–π interaction and electron delocalization, TAPQ/rGO features enhanced cycling stability and ion/electron transportation. Consequently, the composite electrode delivers a reversible capacity of 181.7 mAh g−1 at 0.5 A g−1 and achieves an ultrahigh capacity retention of 94.5% over 10 000 cycles at 5 A g−1, surpassing most reported anodes in AAIBs. Combining density functional theory (DFT) calculation and ex situ electrochemical characterizations, the unique storage mechanism of chelation coordination between NH4+ and N, O is revealed. Furthermore, a high‐performance NH4+‐based full cell, assembled with TAPQ/rGO anode and copper hexacyanoferrate (Cu‐HCF) cathode, demonstrates long‐term cycling stability with 93.95% capacity retention after 500 cycles. This work pioneers the concept of π–π interactions to significantly improve NH4+ storage performance, presenting a novel strategy for the advancement of AAIBs research.

AbstractEnsuring access to safe and affordable drinking water universally is a principal target incorporated in Sustainable Development Goal 6 (SDG 6). This study investigates the role of the Dhulikhel Water Treatment Plant (DWTP) in Nepal in localizing SDG 6 at the municipal level. The study employed a mixed‐methods approach incorporating Key Informant Interviews (KII), Household Surveys, and Water Quality Tests to comprehensively assess DWTP's impact on the supply of safe and affordable drinking water. Water quality test results showed a pH of 8.02, 2 coliforms in 15 samples, no presence of Escherichia coli, 0.02 Mg/l ammonia, 0.75 NTU of turbidity, and 0.2 Mg/l Free Residual Chlorine (FRC). Overall, the parameters of treated samples, including electrical conductivity, pH, temperature, turbidity, calcium hardness, chloride, ammonia, nitrate, phosphate, total coliform, and Escherichia. coli, showed significant differences against untreated samples at a 0.01 level of significance (i.e., p‐value < 0.01). The results underscore DWTP's effectiveness in reducing impurities, eliminating harmful pathogens like E. coli, and improving water clarity and purity. Compliance with prescribed World Health Organization (WHO) standards and National Drinking Water Quality Standards (NDWQS) further validates the treated water's quality. However, the identification of total coliform in some treated samples highlights the need for enhanced microbial management and monitoring within the distribution and supply system. The study also discusses the complex dynamics of water tariffs and the upstream‐downstream conflicts. The study recommends granular local‐level measures to address potential contamination points in the distribution area and ensure equitable supply within the hill town of Dhulikhel.
Memory-Objects and Journeys of Re-collection
Authors: Jacob Ramalho Joana 
Published: November 2024

AbstractDeparting from a close analysis of Portrait of Jennie, and with reference to Laura (Preminger, 1944), Corridor of Mirrors (1948), and Vertigo (Hitchcock, 1958), among other films, this chapter lays out my understanding of the term ‘memory’. Expanding on its intricacies, the chapter characterises gothic protagonists as re-collectors whose movements of search drive the films and posits that the gothic aesthetic exists in places and under certain forms that critics do not usually explore. Such is the case with objects: in the course of the films, particular objects stand out from the mise-en-scène and acquire specific properties that shape the onscreen journeys of the characters and our viewing experience. The Gothic, I suggest, builds on the hoarding and retrieval of memories through what I call ‘memory-objects’: objects that stand for or have become memory, including photographs and wax figures. In this sense, my readings construct re-membering as a spatial act and memory as placeable and tangible. In its tangibility, memory might become transmissible, running the risk of being co-opted by others. This strengthens my overarching argument that the aesthetic foregrounds an exilic discourse wherein the self becomes divorced or estranged from its identity as it tries to recover the past.

Asymptotic Stability of Delayed Complex Balanced Reaction Networks with Non-Mass Action Kinetics
Authors: Vághy Mihály A. , Szederkényi Gábor 
Published: November 2024

Abstract
We consider delayed chemical reaction networks with non-mass action monotone kinetics and show that complex balancing implies that within each positive stoichiometric compatibility class there is a unique positive equilibrium that is locally asymptotically stable relative to its class. The main tools of the proofs are respectively a version of the well-known classical logarithmic Lyapunov function applied to kinetic systems and its generalization to the delayed case as a Lyapunov–Krasovskii functional. Finally, we demonstrate our results through illustrative examples.

Authors: Koskela Heikki O. , Kaulamo Johanna T. , Lätti Anne M. 
Published: November 2024

Abstract
Purpose
To clarify the associations of climatic indices with chronic respiratory symptoms, with a final aim to approximate the effects of climate change on them.

Methods
An e-mail survey was directed to the members of the Finnish Pensioners` Federation. The mean 20-years’ precipitation and temperature in each subjects’ home municipality were obtained from the Finnish Meteorological Institute, separately for summer and winter. Adjusted multivariate models were utilized to investigate the associations of the climatic indices with chronic rhinosinusitis, chronic cough, wheezing with dyspnea, and sleep apnea.

Results
There were 6189 responders from 283 municipalities. Chronic rhinosinusitis and chronic cough were most prevalent in the southeastern regions of the country, where the precipitation counts were highest. In the multivariate models, winter precipitation in the home municipality increased the risks of chronic rhinosinusitis and chronic cough [adjusted OR 1.80 (1.30–2.51) per 100 mm, p < 0.001, and 1.57 (1.19–2.07) per 100 mm, p = 0.001, respectively]. Wheezing with dyspnea and sleep apnea were not associated with the climatic indices.

Conclusion
Chronic rhinosinusitis and chronic cough were associated with long-term winter precipitation. Given the anticipated increase in winter precipitation in Northern America and Northern Europe, the prevalences of chronic rhinosinusitis and chronic cough may increase there.

Using DSLs to manage consistency in long-lived enterprise language specifications

Published: November 2024

AbstractModern enterprise systems are likely to have a very long life. Their specifications therefore need to employ mechanisms that allow them to evolve during their lifetime; where they exploit generic components, these must be adaptable for use in novel situations. The paper looks at some of the issues that arise from this requirement, and how the exploitation of domain-specific language technologies in the tool-chain can assist in maintaining consistency of the specification as a whole. First, it reviews the final state of the family of standards supporting the ODP Enterprise Language, which is intended to handle this kind of application. In particular, it looks at the way the framework for defining policies can be used to accommodate changing requirements during the lifetime of an evolving system. It also looks at the way the idea of deontic tokens enables factoring out of the management of obligations from the basic behaviour of interacting system components. It then proposes a roadmap for building tools that can be used to unify the constraints from different areas of concern into a single specification. The approach taken is to exploit the power of domain-specific languages (DSLs) to allow designers in the various areas of concern to provide their input in terms natural to them. Finally, it looks at the way this approach promotes the establishment of a robust tool-chain capable of handling the evolution and scalability of enterprise systems. The paper uses a running example from the e-health domain to show how specific areas identified in the e-health standards can lead to language definitions, and so to tooling, that can be used to manage unified, system-wide specifications.
