A comparative study with PS reveals similar product distributions, indicating that FPD waste additives do not significantly impede the catalytic reactions. Zeolitic catalysts (HZSM-5, Hβ, and HY) effectively reduce nitrogen- and oxygen-containing compounds and also styrene with increase in BTEX and polycyclic aromatic hydrocarbons (PAHs) yields. Even at a feed:catalyst ratio of 1:1, distinct product distributions are observed compared to the noncatalytic run. In the presence of Hβ, benzene is the main compound, exhibiting a 22% increase. With HY, ethylbenzene is the dominant product, showing a 36% increase.

In this study, we report an innovative approach to develop composite membranes for producing laser-engineered graphene electrodes (LEGEs) for electrochemical sensing. Composite membranes were prepared by blending aminated polyethersulfone (H2N-PES) with carbon black (CB) at different weight ratios (0.1, 0.2, and 0.3 wt%). The resulting composite membranes served as scaffolds for preparing LEGEs. Both the composite membranes and the derived LEGEs were thoroughly characterized using spectroscopic, thermal, electrochemical, and scanning electron miscroscopy techniques. The results showed that the incorporation of CB into the polymer substantially enhanced the electrochemical performance compared to the pristine H2N-PES membrane, particularly for the membrane containing 0.3 wt% loading of CB; it can be used for ascorbic acid determination in the concentration range of 10–300 µM with a detection limit of 2.45 µM, with high selectivity over uric acid and dopamine. LEGEs were successfully applied for the selective electrochemical sensing of ascorbic acid in spiked solutions and in commercial orange juice samples.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"90 10","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144833609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of substituents and solvent polarity (tetrahydrofuran (THF) and chloroform (CHCl3)) on the linear absorption and fluorescence properties are systematically investigated. The target aza-BODIPYs exhibit higher absorption in CHCl3 compared to THF. While solvent polarity exerted a minimal effect on the absorption and fluorescence intensity, the fluorescence in BOD2 and BOD3 is markedly quenched as a result of the electron-donating methoxy groups and the pronounced intramolecular charge transfer (ICT) characteristics of the diphenylamine unit. Moreover, all compounds shows strong near-infrared two-photon absorption (TPA) behavior. The TPA cross-sections of BOD1 and BOD3 are measured as 61 and 269 GM at 1000 nm, respectively, and BOD3 showed the highest value due to the enhanced ICT efficiency. Density functional theory calculations are also performed to study the thermodynamic and photophysical properties in different media. The findings indicated an enhancement in molecular stability and a reduction in HOMO–LUMO gaps, particularly in THF.

Nevertheless, side reactions occur with oxygen either present in the reactive molecular fluorine gas (F2) or during a post-reaction when the sample is exposed to air atmosphere. A systematic study of the fluorination of polypropylene at different temperatures identifies the formation of acyl fluoride COF groups, coexisting with the fluorinated groups. COF groups evolve into carboxylic acid (COOH) groups during the first few hours after fluorination. Despite the presence of fluorine, the polar component of the surface energy increased. By introducing an esterification post-treatment of the COF groups with an alcohol in the gas phase after the fluorination step, it is possible to stabilize the surface chemistry and thus prevent its hydrolysis. Surfaces post-treated by this singular approach are less hydrophilic than their counterparts only treated by direct fluorination.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"90 10","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144793063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The accumulation of metal ions, including iron-heme, their interaction with amyloid-β (Aβ) peptides and their ability to catalyze reactive oxygen species formation significantly contribute to the pathogenesis of the disorder. These factors are highly dependent on the surrounding environment, whether intracellular, extracellular, or membrane-associated. In this study, the interaction between heme and Aβ within a membrane-mimicking system using sodium dodecyl sulfate is investigated. UV–vis and circular dichroism data indicate that the heme/Aβ complex can be sequestered within the micelle, leaving part of Aβ largely exposed at the surface. The presence of the micellar environment significantly affects both the stability and aggregation state of the hemin group, as well as its accessibility to peptide coordination and to external molecules, such as phenols and catechols. Indeed, peroxidase-like activity studies show that the overall reactivity of the hemin–Aβ complex is markedly reduced under these conditions. Overall, these results suggest that a membrane-like environment may offer partial neuroprotection against heme-induced toxicity by limiting the formation of the heme–Aβ complex and the oxidative damage to nearby biomolecules, including neurotransmitters.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"90 10","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/cplu.202500304","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144787908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is owing to their electrochemical activity that results in unique optical transmission, modulating with applied potential. The molecular design rules of electrochromes are well established, consisting of electroactive components such as viologens, rhodamines, and transition metal complexes. While molecular electrochromes offer the advantage of establishing accurate structure/property relationships for tuning the optical transmission contingent on molecular structure, their physisorption on the electrodes limits the performance of electrochromic devices. Indeed, molecular electrochromes suffer from poor performance compared to their polymer counterparts in operating electrochromic devices. This perspective presents approaches to overcome these challenges. Focus is given to various strategies of covalently attaching molecular electrochromes to the device electrode for improving key electrochromic properties of contrast ratio and coloration efficiency. These operating device metrics are improved compared with the physisorption of molecular electrochromes via noncovalent interactions. The overarching goal is to provide useful insight that can be leveraged for the rational design of molecular electrochromes for their covalent attachment to electrodes toward matching device metrics of their polymer counterparts.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"90 9","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/cplu.202500178","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144787907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
