Antimicrobial materials are a crucial component in eradicating and managing the spread of infectious diseases. They are expected to act on a broad-spectrum of microbes, including emerging pathogens which could cause the next Disease X. Herein, we reassessed a series of antimicrobial imidazolium polymers on our shelves and uncovered extended functionality through dual modes of action. By redesigning their structures, a truly broad-spectrum antimicrobial material with optimized activity against bacteria (G +ve, G -ve) and fungi, as well as enveloped and non-enveloped viruses was developed. We demonstrated that the imidazolium polymer exhibits dual modes of function against microbes: targeting the microbial membrane and binding DNA. The latter DNA binding affinity was found to be key against non-enveloped viruses. With this insight, we designed small molecule compounds that exhibited optimum broad-spectrum antimicrobial activity and excellent efficacy against ESKAPE group of pathogens that are responsible for some of the deadliest nosocomial infections worldwide. Our results could also shed light on the design of broad-spectrum antimicrobial compounds against Disease X.
抗菌材料是消除和控制传染病传播的重要组成部分。在此,我们对货架上的一系列抗菌咪唑聚合物进行了重新评估,并通过双重作用模式发现了其扩展功能。通过重新设计其结构,我们开发出了一种真正的广谱抗菌材料,对细菌(G +ve、G -ve)、真菌以及包膜和非包膜病毒具有最佳活性。我们证明,咪唑聚合物对微生物具有双重作用模式:靶向微生物膜和结合 DNA。我们发现,后者的 DNA 结合亲和力是对抗无包膜病毒的关键。有了这一认识,我们设计的小分子化合物表现出了最佳的广谱抗菌活性,对 ESKAPE 类病原体具有卓越的疗效,这些病原体是造成全球一些最致命的院内感染的罪魁祸首。我们的研究结果还有助于设计针对 X 病的广谱抗菌化合物。

Green solvents such as water and ionic liquids (ILs) are pillars of the great mansion of green chemistry and green processing. Initially proposed as a new family of ILs, deep eutectic solvents (DESs) have received fast development in the past two decades. In this contribution, DESs are reviewed critically and the concept is extended to low-melting mixture solvents (LoMMSs), which cover all kinds of materials including ionic compounds, molecular compounds, and metals. Six classes of LoMMSs are proposed as the new classification system and examples are given. Finally, several thermodynamic issues concerning LoMMSs are discussed. Two new concepts, robustness of LoMMSs and high-entropy LoMMSs, are proposed.

Cooling water systems (CWSs) are extensively utilized in various industries to eliminate the excess heat and converse energy. Studies on CWSs mainly concentrated on finding the optimal cooler network structure. In addition, some works also considered the optimal design under varied operation conditions. However, in these works, once the optimal design of the cooler's network is determined, its arrangement remains fixed and cannot be adapted to accommodate diverse operating conditions. In this work, a flexible topology network concept is proposed to make the adjustment of network structure possible under different operation conditions. The CWS with integrated air cooler and flexible topology network has better overall performance, represented by a mixed integer nonlinear programming (MINLP) model that require advanced tools such as GAMS software. Case studies revealed that the proposed methodology can realize better energy-saving performance, and improve the economic performance under varied operation conditions. The impact of critical flexible nodes on system configuration and economy is achieved by sensitivity analysis.

In order to improve the electrical conductivity of nylon 6 (PA6) and avoid misfires and explosions caused by static charge accumulation, a quaternary ammonium salt polyionic liquid (PIL) antistatic agent was synthesized in this paper. The surface resistance of PA6 was reduced to 108 Ω with the addition of 2 wt% antistatic agent, and the mechanical properties and aging resistance of the substrate were improved. Meanwhile, the morphology and crystallinity of PIL/PA6 composites were further characterized by scanning electron microscope (SEM), energy dispersion spectrometer (EDS) and X-ray diffraction (XRD). It is worth noting that the quaternary ammonium salt polyionic liquid antistatic agent synthesized in this paper has the advantages of excellent antistatic effect, durability, low cost, and simple reaction condition, so it has a broad application prospect in the antistatic aspect of PA6.

With more and more lithium-ion batteries (LIBs) being put into production and application, precious metals such as lithium and cobalt are scarce, so it is imminent to recover various strategic metal resources from spent LIBs. Meanwhile, the complex and difficult problem of separating and recovering metals from leaching solutions has been an urgent question that needs to be resolved. In this work, a phosphoric acid-based deep eutectic solvent (DES) was developed for extracting metals from spent LIBs and one-step selectively separating and efficiently recovering transition metal. The prepared DES shows excellent extraction performance for Li (100%) and Co (92.8%) at 100 °C. In addition, the extraction system can effectively separate and precipitate Co through its own components, avoiding the introduction of new precipitants and the destruction of the original composition structure of DES. This also contributes to the good cycle stability of the extraction system with excellent extraction performance for Li (94.3%) and Co (80.8%) after 5 cycles. This work proposes a green method for one-step selectively separating and recovering valuable metals from spent LIBs.

CO2 conversion is gradually seen as a better way for society to effectively use carbon sources and avoid climate crisis associated with fossil CO2 emissions. And the decision to deploy CO2 technology scale should be relied on its environmental impact. In this work, life cycle assessment model evaluates the environmental performance of CO2 conversion by photocatalytic reaction process with two different catalysts (NiAl-LDH and Co-ZIF-9). Six impact categories considered in this analysis, including climate change, acidification potential, depletion of abiotic resources, eutrophication potential, ozone layer depletion potential, and photochemical oxidation potential. Results indicated that CO2 conversion with Co-ZIF-9 photocatalyst has a better environmental impact than the NiAl-LDH photocatalyst route. Moreover, the Co-ZIF-9 catalyst scenario also has a lower total environmental burden than the conventional CO production route. Sensitivity analysis shows that recycle performance of the catalyst is highly sensitive to the production process in two scenarios. This study could provide a framework for robust decisions in CO2 conversion by photocatalytic reaction, which is useful for policymakers to decide the feasibility of industrialization.
二氧化碳转化逐渐被视为社会有效利用碳源、避免化石二氧化碳排放带来的气候危机的更好途径。而二氧化碳技术规模的决定应依赖于其对环境的影响。在这项工作中,生命周期评估模型评估了采用两种不同催化剂(NiAl-LDH 和 Co-ZIF-9)的光催化反应过程转化二氧化碳的环境性能。该分析考虑了六个影响类别,包括气候变化、酸化潜力、非生物资源损耗、富营养化潜力、臭氧层破坏潜力和光化学氧化潜力。结果表明,与 NiAl-LDH 光催化剂路线相比,Co-ZIF-9 光催化剂的二氧化碳转化具有更好的环境影响。此外,Co-ZIF-9 催化剂方案的总环境负担也低于传统的 CO 生产路线。敏感性分析表明,在两种方案中,催化剂的回收性能对生产工艺非常敏感。这项研究可为光催化反应转化二氧化碳的稳健决策提供一个框架,有助于决策者决定工业化的可行性。

With the intensifying challenge of global warming driven largely by anthropogenic activities, effective greenhouse gas capture techniques are critical. This paper focuses on the role of deep eutectic solvents (DES) as promising agents for such capture at the source. We review the key DES-based methods for greenhouse gas capture, drawing conclusions from a thorough analysis of the existing literature. In particular, we examine the effect of DES structure on gas solubilities and explore the mechanism of gas solubility in DES through molecular simulation. We present a synthesis of state-of-the-art results in this area, assessing the potential of DES as an alternative to current industrial gas capture methods. Furthermore, we propose future research directions for the design of novel DES tailored to more specific applications.

Furthermore, we propose future research directions for the design of novel DES tailored to more specific applications.</p></div>","PeriodicalId":66474,"journal":{"name":"Green Chemical Engineering","volume":null,"pages":null},"PeriodicalIF":9.1,"publicationDate":"2023-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666952823000468/pdfft?md5=9306b430a9627778ba1e10434079c304&pid=1-s2.0-S2666952823000468-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135389599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
