Berg is a native Brazilian species with promising compositional and functional attributes. Its leaves contain a variety of phenolic compounds and volatile constituents with potential antioxidant properties, but their food applications remain poorly explored. This study evaluated the influence of leaf particle size on the physicochemical composition, bioactive profile, and sensory properties of <i>C. adamantium</i> infusions, with commercial teabag applications in mind. Leaf samples were ground to three granulometries (10, 20, and 32 mesh) and infused using distilled or tap water to simulate controlled and domestic preparation conditions. Physicochemical parameters, total phenolic, flavonoid, and tannin contents, antioxidant potential, and liquid chromatographic analysis were performed. A consumer panel (<i>n</i> = 100) assessed appearance, aroma, taste, astringency, flavor intensity, and purchase intention. Finer particles increased the extraction efficiency, resulting in higher antioxidant activity, particularly in infusions prepared with distilled water. However, sensory acceptance decreased for the 32-mesh samples. The 20-mesh particle size provided the optimal balance between chemical composition and sensory acceptance. These results demonstrate the potential of <i>C. adamantium</i> leaves for the development of value-added infusions, underscoring the influence of water composition on extractability.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"80 8","pages":"9217 - 9227"},"PeriodicalIF":2.5,"publicationDate":"2026-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148783386","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}

We have developed a dual-site responsive monobrominated 2-[<i>O-</i>(<i>1-ethyloxyamide</i>)] oxime-4-bromophenol (BrHS) probe, which demonstrates bidirectional fluorescence responses. Specifically, arginine (Arg) induces a 2.2-fold increase in fluorescence intensity with a detection limit of 246 pM through proton-transfer complexation. In contrast, glutathione (GSH) triggers selective fluorescence quenching with a detection limit of 372 pM via γ-glutamyl-specific hydrogen bonding (O···H–N) and nucleophilic aromatic substitution (SNAr). Real-time cellular imaging conducted in MCF-7 cells enables dynamic monitoring of GSH levels, with observations of dose-dependent fluorescence quenching. Density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations reveal that glutathione (GSH) exhibits a substantial thermodynamic advantage. Specifically, the Gibbs free energy change (ΔG) of GSH is − 201.75 kJ/mol, indicating it is approximately 14.9 times more reactive than cysteine (Cys). These findings are corroborated by Mayer bond order analysis and electrostatic potential (ESP) charge distribution data. The probe exhibits a wide pH response range and rapid response times (&lt; 10 s for Arg, &lt; 60 s for GSH), enabling effective detection in complex real-world samples. This semi-system, akin to Salamo, presents a novel methodology for dual analyte tracking and detection with atomic-scale specificity, thereby offering transformative potential for the diagnosis of oxidative stress.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"80 7","pages":"7763 - 7774"},"PeriodicalIF":2.5,"publicationDate":"2026-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148553019","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}

A cotton fabric was coated with GO, rGO and graphene by dip coating method and their properties were evaluated. The treated cotton fabrics showed resistivity in the range of ~ 2–9 kΩ that confirmed the conversion of resistive cotton into e-conductive fabric. Excellent UV-protection property was exhibited in cotton stalk rGO and biomass rGO coated fabrics with UPF 175 and 98, respectively.

This review discusses emulsion nanofluid membranes (ENM), a revolutionary water treatment method in which nanofluids are directly integrated into the organic (membrane) phase of the emulsion liquid membrane (ELM) to function as Pickering stabilizers, hence improving emulsion stability, mass transfer rate, and antifouling characteristics while improve the stability, selectivity and efficiency of the process in the removal of the pollutants. ENM are water–oil-water (<i>W/O/W</i>) systems, which capitalize on nanofluids (e.g., <i>Fe</i>₃<i>O</i>₄<i>, SiO</i>₂<i>, Al</i>₂<i>O</i>₃) to improve the process of mass transfer, reduce the level of fouling, and extract and stripping contaminants. This incorporates surfactants (e.g., <i>Span 80</i>), extractants (e.g., <i>CYANEX 272, D2EHPA</i>), diluents (e.g., kerosene), and stripping agents (e.g., NaOH, HCl). Choice of the stripping agent (NaOH for cationic metals/dyes or HCl for anionic species and drugs) is based on the targeted pollutant charge, pH dependence speciation, and compatibility with the carrier to ensure efficient back-extraction while decreasing emulsion breaking. In preparation, nanoparticles are chosen, emulsified and their characterization through methods like DLS, zeta potential, SEM, TEM, FTIR and NMR. Applications have shown &gt; 95% removal efficiencies, which is better than conventional methods in flux (to 45% better), rejection, antifouling, and energy savings. The comparison shows that ENM are better permeable, mechanically stable, and can be recycled. Challenges include emulsion instability and high initial costs of nanomaterial; however, organic chemicals (surfactants, extractants, and diluents) are affordable, recyclable, and reusable for several cycles, making the whole process cost-effective on a large scale. Nanoparticle adsorption at the oil–water interface (Pickering stabilization), optimal surfactant concentration, and stability of emulsification parameters are the best methods for preventing emulsion instability. Emulsion Nanofluid Membranes are widely employed in resource recovery, environmental remediation, and sustainable water purification procedures due to their excellent selectivity, increased mass transfer performance, and energy-efficient operation. The purpose of (ENM) has been presented as a next-generation, energy-efficient resource recovery technology platform that offers resource recovery, higher flux, and additional antifouling its resources during comparison with existing technologies, thereby helping to solve the global water scarcity and circular-economy objectives.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"80 10","pages":"11501 - 11529"},"PeriodicalIF":2.5,"publicationDate":"2026-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149007408","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}

These compounds stand out due to their inherent redox properties, ability to generate reactive oxygen species (ROS), and selective toxicity toward cancer cells. Furthermore, their structural similarity to endogenous metalloenzymes allows them to interfere with vital cellular pathways, positioning them as promising anticancer agents. Chelation plays a pivotal role in amplifying the biological performance of these copper complexes. By stabilizing the metal center, chelation enhances solubility, membrane permeability, and targeted delivery. It also strengthens DNA-binding affinity through intercalation, groove binding, or backbone interaction, promoting DNA damage and apoptosis in tumor cells while sparing healthy tissues. These chelated systems exhibit improved pharmacokinetics and reduced systemic toxicity, offering a significant therapeutic edge over conventional treatments.

By using elastic parameter computation, both alloys have achieved mechanical stability. The ductile character of PtMnSbV and brittle nature of NiMnSbV is confirmed. A higher H_V value for PtMnSbV as compared to NiMnSbV suggests that PtMnSbV has better pressure indentation resistance.
