These characteristics can significantly enhance the sensitivity and selectivity of electrochemical detection. In this study, a differential pulse anodic stripping voltammetry (DPASV) method was developed for the simultaneous determination of Cd²⁺ and Pb²⁺ in food samples using a gold electrode modified with a ZnO QDs/Nafion nanocomposite film. ZnO QDs were synthesized via a sol–gel method by reacting zinc acetate with potassium hydroxide in ethanol under controlled temperature and continuous stirring. The fabricated electrode was characterized in terms of surface morphology, electrochemical behavior, and analytical performance toward Pb²⁺ and Cd²⁺ detection. The optimal electroanalytical conditions were as follows: acetate buffer (pH 5.0), deposition time of 90 s, pulse amplitude of 0.04 V, and electrode cleaning time of 20 s. Under these conditions, the proposed method exhibited a linear response for Pb²⁺ in the concentration range of 1.9 × 10⁻⁸ to 1.2 × 10⁻⁷ mol L⁻¹, with a detection limit (LOD) of 5.6 × 10⁻⁹ mol L⁻¹. For Cd²⁺, a linear range of 7.7 × 10⁻⁸ to 2.1 × 10⁻⁷ mol L⁻¹ was obtained with an LOD of 2.3 × 10⁻⁸ mol L⁻¹. The proposed method demonstrated good sensitivity, selectivity, and repeatability, and was successfully applied to the simultaneous determination of Pb²⁺ and Cd²⁺ in food samples, including coffee powder, Thai Nguyen tea, fish, and chicken.</p>\u0000 </div>","PeriodicalId":520,"journal":{"name":"Colloid and Polymer Science","volume":"304 7","pages":"1739 - 1752"},"PeriodicalIF":2.9,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148299945","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}

Nevertheless, modification mechanism and level are blurry especially at a higher dose irradiation, restraining deep functional material design. In this work, pure corn starch was irradiated by an EB in air with dose up to 500 kGy. Then, microstructural and physicochemical property variations were explored via FT-IR, XPS, ¹³C-NMR, GPC, XRD, SEM, whiteness, TGA and viscosity analysis. Later, its post acceleration effect was explored via AA grafting. Main results reveal that irradiation induced severe starch backbone scission. Cleavage mainly occurred at <i>α</i>-1,4 glycosidic bond and the link of C-1 and C-2 atoms within starch glucose unit. Upon 500 kGy irradiation, number-average molecular mass-<i>Mn</i>-decreased from 2.56 × 10⁵ to 1.33 × 10³ Da, conversing macromolecule to small molecule debris. Certain hydroxyls were oxidized to carbonyls. Molecule chain stacking regularity was destroyed. Amorphization occurred shown a crystallinity reduction close to 34%. Synchronously, color be darken, cracks and micropores were generated, thermal-stability and viscosity decreased. In details, whiteness and viscosity decreased from 91.3 ± 0.1 and 1539 ± 5 to 45.3 ± 1.6 and 0 mPas and the fastest speed thermal-decomposition temperature decreased by 6 °C. It seems a dose of 500 kGy EB irradiation deteriorated starch microstructure and physicochemical property sufficiently. However, it promotes post AA grafting efficiently. Via a dose of 100 kGy EB irradiation and certain level AA grafting a QH₂O as 687.9 ± 19.5 sample was achieved, showing a 1.16 times elevation compared to sample without pre-irradiation, implying sufficient acceleration effect. These findings promote EB irradiation technology use in starch-based functional material design and starch irradiation damage mechanism, sustaining visible use and academic values.

The network structure of hydrogel was generated by ionic crosslinking process with using 2% calcium chloride (CaCl₂) as gelling agent. It was observed that higher Alg content resulted in faster gelation, greater swelling behavior in both deionized water and saline solution, due to the increased number of hydrophilic carboxyl groups. On the other hand, in terms of mechanical properties, the 2% alginate hydrogel exhibits optimal mechanical performance. Therefore, 2% alginate was selected as the suitable concentration for the preparation of polymer blend hydrogel composites. The study of polymer blending demonstrates that the abundance of hydroxyl groups in PVA enhances water uptake in hydrogel composites (Alg/PVA and Alg/PVA/PVP). However, these hydroxyl groups also promote hydrogen bonding, leading to increased rigidity of the hydrogel films. In contrast, Alg/PVP blending shows no significant influence on the swelling behavior of the hydrogels, although PVP improves elongation at break. As a result, the ternary Alg/PVA/PVP hydrogel composite exhibits synergistic effect, significantly enhancing optimal balance between mechanical strength and flexibility.</p>\u0000 </div>","PeriodicalId":520,"journal":{"name":"Colloid and Polymer Science","volume":"304 7","pages":"1687 - 1702"},"PeriodicalIF":2.9,"publicationDate":"2026-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148299995","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}

One was to use multi-walled carbon nanotubes (MWCNTs) both as conductive filler and particle-typed emulsifier for building a Pickering emulsion analogue to achieve mixing with POFC prepolymer (pre-POFC); the other is to use choline chloride (ChCl) as conductive agent to solvent-blend with pre-POFC. For the constructed MWCNT/POFC electronic conducting elastomers, MWCNT formed a 3D network without affecting POFC cross-linking, enhancing tensile strength (7-fold), Young’s modulus (10-fold) and conductivity (nearly 2 orders of magnitude) at 5 wt% loading. For the constructed ChCl/POFC ionic conducting elastomers, ChCl interacted with POFC (covalent/non-covalent bonds) or existed freely, impairing cross-linking and mechanical properties, but boosting conductivity by nearly 3 orders of magnitude at 10 wt% loading, with stretch-insensitive electrical response and stable recovery.
