Four strategies have been investigated for improving the melt processability of UHMWPE, which is the chief limiting factor to the applications of this high-performance polymer. 1) Active site engineering was used to explore the entanglement density in the resulting polymer, with substantially disentangled PE identified through thermal and rheological characterisation. 2) Hydrogen and ZnEt<small>₂</small> were employed as chain transfer agents to modulate the polyethylene molecular weight and distribution (MWD). A sequential reactivity protocol using ZnEt<small>₂</small> was able to produce bimodal UHMWPE with improved processability. 3) MWD tuning was further investigated using multisite catalysts, with the reaction conditions and Ti : Zr ratio able to control MWD to essentially arbitrary shapes. The inclusion of low molecular weight fractions into UHMWPE improves the processability without compromising mechanical characteristics. 4) Polymer-reinforced composite blends of UHMWPE with either HDPE or LDPE as a highly processable matrix were extruded and explored, with polymer miscibility and mechanical properties studied in detail.</p><p>Keywords: Ultra-high molecular weight polyethylene; Processability; Molecular weight distribution; Polymer composites; Chain transfer agents.</p>","PeriodicalId":29808,"journal":{"name":"Industrial Chemistry & Materials","volume":" 2","pages":" 178-190"},"PeriodicalIF":0.0,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/im/d4im00104d?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667776","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}

To address concerns such as electrolyte leakage and flammability, solid polymer electrolytes (SPEs) have emerged as promising alternatives to liquid electrolytes. SPEs, particularly those synthesized <em>via in situ</em> polymerization processes, offer advantages in establishing robust interface contacts and compatibility with existing industrial production lines. However, the electrochemical stability of SPEs remains a hurdle for high-voltage lithium metal batteries (LMBs). To enhance interface uniformity, electrochemical stability, and thermal stability, researchers commonly employ fluorination strategies, thus expanding the potential of SPEs in high-voltage, long-cycling LMBs. Fluorine plays a crucial role in achieving these objectives due to its high electronegativity, polarization, outstanding dielectric properties, strong bond strength, stability, and hydrophobic nature. In this study, we delve into how fluorinated electrolytes improve interface stability between SPEs and electrodes by examining their underlying mechanisms. Besides, we provide an overview of current fluorination strategies and their impact on battery performance. Furthermore, we discuss challenges and issues associated with current <em>in situ</em> polymerized fluorinated SPE routes and propose practical strategies for consideration.</p><p>Keywords: Lithium metal batteries; <em>In situ</em> polymerization; Fluorinated polymer electrolytes; High-voltage; Long cycling; Stable interface.</p>","PeriodicalId":29808,"journal":{"name":"Industrial Chemistry & Materials","volume":" 2","pages":" 151-177"},"PeriodicalIF":0.0,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/im/d4im00082j?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667775","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}

Herein, a three-dimensional porous carbon felt-loaded PbO<small>₂</small> electrode (PbO<small>₂</small>/CF) with a self-supported nanostructure was fabricated using a double-cathode electrodeposition method, which served as an efficient electrocatalyst enabling the unique sequential paired electrosynthesis of 1,4-hydroquinone (1,4-HQ) from phenol in a membrane-free electrolytic cell. In such an exotic paired electrolysis system, phenol is first oxidized to <em>p</em>-benzoquinone at the anode, which is subsequently reduced to 1,4-HQ at the cathode. The as-obtained PbO<small>₂</small>/CF electrode exhibited a remarkable electrochemical performance, achieving impressive conversion and selectivity of 94.5% and 72.1%, respectively, for the conversion of phenol to 1,4-HQ. This exceptional performance can be attributed to the open porous self-supported structure of the PbO<small>₂</small>/CF electrode, which improves the active site exposure and substrate adsorption capability and reduces mass and charge transfer resistance. Furthermore, the catalyst electrode well maintained its structure integrity even after 140 hours of long-term use, further highlighting its promising application for the electrosynthesis of 1,4-HQ. Moreover, this sequential paired electrosynthesis strategy can be further extended to other substrates with electron-withdrawing/donating groups over the PbO<small>₂</small>/CF electrode.

The rapid and reliable detection of urine APAP concentration can offer certain guidance for better management of APAP usage. This study explored the electrochemical sensing application of a novel electrocatalyst prepared from the biomass of <em>Elaeagnus angustifolia</em> gum. The biomass was first activated by ferric chloride to form a porous biomass carbon material (FBC). Then cobalt oxide (CoC) cracked nanoplate were synthesized by alkali precipitation and calcination and were then hybridized onto the biomass carbon <em>via</em> a simple sonication process. The electrocatalyst of CoO-FBC was characterized by scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS), element mapping, transmission electron microscopy (TEM) and high resolution (HR-TEM), X-ray photoelectron spectroscopy (XPS), X-ray powder diffraction (XRD), thermogravimetric analysis (TGA), Raman spectroscopy, and nitrogen adsorption/desorption analysis. The CoO-FBC modified glassy carbon electrode (CoO-FBC/GCE) was characterized by various electrochemical methods including cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and differential pulse voltammetry (DPV). The CoO-FBC/GCE sensor was used to measure APAP in 0.1 M phosphate buffered saline (PBS) with a pH of 7.0, and with two linear sensing ranges from 1 μM to 10 μM and from 10 μM to 100 μM, with a sensitivity of 25.89 μA μM<small>⁻¹</small> cm<small>⁻²</small> and 10.04 μA μM<small>⁻¹</small> cm<small>⁻²</small>, respectively, and a limit of detection of 0.46 μM. The unavoidable interference in measuring APAP is the inherent uric acid in urine. Uric acid and APAP exhibited adjacent and sometimes unseparable voltammetric peaks. This CoO-FBC/GCE sensor is capable of distinguishing APAP from uric acid and so APAP can be measured in human urine samples with good recoveries. This CoO-FBC/GCE sensor is a promising application for clinical diagnosis and environmental detection.</p><p>Keywords: <em>Elaeagnus angustifolia</em> gum; Ferric chloride; Polysaccharide biomass; Cobalt oxide nanoplate; Electrochemical sensing; Analgesic and antipyretic drug.</p>","PeriodicalId":29808,"journal":{"name":"Industrial Chemistry & Materials","volume":" 1","pages":" 97-108"},"PeriodicalIF":0.0,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/im/d4im00069b?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141737513","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}
