To circumvent these limitations, we engineered a multifunctional, self-assembled coordination nanoplatform-DOX/DMY-Fe 3+ @PEG nanoparticles (DDFP NPs)-driven by the metal-phenolic coordination between Fe 3+ , DOX, dihydromyricetin (DMY), and polyethylene glycol (PEG)-polyphenols. The resulting DDFP NPs exhibited high drug-loading capacity, robust colloidal stability, and a distinct pH-responsive release profile. Furthermore, the nanoplatform demonstrated a significantly prolonged systemic half-life, which facilitated preferential accumulation within the tumor microenvironment via the enhanced permeability and retention effect. In vitro investigations revealed that DDFP NPs efficiently internalized into U87MG glioma cells, where the co-delivered DMY and DOX synergistically downregulated the expression of aldo-keto reductase family 1 member C3 (AKR1C3) and Survivin. This dual-target reduction not only sensitized tumor cells to DOX-induced apoptosis but also potentially suppressed the bioreduction of DOX into its cardiotoxic metabolite, doxorubicinol (DOXOL). In vivo evaluations in U87MG xenograft models confirmed that DDFP NPs achieved superior antitumor efficacy while markedly alleviating DOX-associated myocardial damage. Collectively, this study establishes a robust nano-strategy that integrates chemosensitization and attenuation of acute cardiotoxicity through a rationally designed coordination system, offering significant potential for clinical translation in anthracycline-based cancer therapy.","PeriodicalId":18530,"journal":{"name":"Materials Research Express","volume":"13 13","pages":"135002-135002"},"PeriodicalIF":0.0,"publicationDate":"2026-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148394378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study used a one-step supercritical methanol hydrothermal method to synthesize ultrafine Co powder, investigating key parameters (reducing/chelating agents, concentrations, and pH). The powder was characterized using scanning electron microscopy, x-ray diffraction, Fourier-transform infrared spectroscopy, x-ray photoelectron spectroscopy, and (derivative) thermogravimetry.

Ni-Mo/BNNS-OH composite coatings with BNNS-OH contents ranging from 0 to 0.5 g l −1 were produced using direct current electrodeposition. It was observed that the incorporation of BNNS-OH refined the grain structure, increased nucleation density, and promoted a uniform nanosheet distribution within the Ni-Mo matrix. At an optimal loading of 0.3 g l −1 , the composite coating achieved a microhardness of 523.69 ± 9.86 HV, a stable friction coefficient of 0.28–0.35, and a reduced wear rate of 8.72 × 10 −6 mm 3 /Nm, outperforming pristine Ni-Mo. The performance enhancements were rationalized by synergistic contributions of microstructural strengthening and solid-lubrication effects. Excessive BNNS-OH content led to nanosheet agglomeration and a subsequent decline in mechanical and tribological properties. These findings highlight BNNS-OH as a promising reinforcement strategy for developing environmentally benign, high-durability coatings for advanced tribological applications.","PeriodicalId":18530,"journal":{"name":"Materials Research Express","volume":"13 3","pages":"035002-035002"},"PeriodicalIF":0.0,"publicationDate":"2026-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147915361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During wastewater treatment, these ultrafine particles resist solid–liquid separation, making recovery and reuse challenging and undermining process stability. To address this issue, we prepared a composite granular adsorbent (HKCGFS-S-B) by sequentially treating CGFS with high-concentration acids and bases (9 mol l −1 HCl then 10 mol l −1 KOH), blending the modified CGFS with 20% pine sawdust by mass, and granulating with a PVA/HPC binder at a 4:3 mass ratio. The resulting pellets maintained high adsorption capacity and mechanical stability over repeated reuse cycles. Under batch conditions (100 mg l −1 initial dye concentration, 328 K, pH 7, and a contact time of 24 h), the adsorbent exhibited strong performance, with capacities of 86.6, 83.0 and 59.3 mg g −1 for Neutral Red, Rhodamine B, and Reactive Brilliant Orange, respectively. Under the same conditions, the adsorbent maintained removal efficiencies above 75%, 67%, and 52% after eight adsorption–desorption cycles. Mechanistic investigation revealed that physisorption was the dominant removal process, as supported by kinetic data fitting the pseudo-first-order model and equilibrium data conforming to the Freundlich isotherm. Physicochemical analysis confirmed that the material possessed a porous carbon structure enriched with silico-aluminate minerals, a specific surface area of 130.51 m 2 g −1 and a pore volume of 0.14 cm 3 g −1 .

In this study, we adopt a novel approach by etching numerous micropores onto the surface of carbon cloth using plasma activation technology, thereby providing growth sites for Bi 2 O 3 nanoparticles during the solvothermal process. This approach enables the preparation of Bi 2 O 3 @PCC composites with uniformly distributed Bi 2 O 3 nanoparticles, yielding electrodes that exhibit excellent rate performance and high areal capacitance. Under a 1 mA cm −2 current density, the area-specific capacitance reaches 3279.7 mF cm −2 . As the current density increases to 20 mA cm −2 , the capacitance retains 61.3% of its value. In contrast, the Bi 2 O 3 @CC composite material without plasma treatment exhibits relatively lower specific capacitance and retention, with values of 1762.2 mF cm −2 and 35.4%, respectively. Thus, it can be concluded that the performance of the composite material Bi 2 O 3 @PCC has significantly improved compared to that prepared with untreated carbon cloth.

However, the current photopolymer materials for 3D printing dental applications often fail to yield the required quality due to their inferior mechanical properties. Thus, this study aims to explore the effects of silanized nano-Al 2 O 3 fillers on the mechanical properties and printing accuracy of one of the most commonly used photopolymer resins, polyurethane acrylate (PUA). The modification of nano-Al 2 O 3 particles by the silane coupling agent was characterized by Fourier-transform infrared spectroscopy (FTIR) and thermogravimetric (TGA) analysis. Then, specimens were fabricated using PUA resins with 0 wt% (control), 2 wt%, 4 wt%, and 6 wt% silanized nano-Al 2 O 3 fillers. The effects of silanized nano-Al 2 O 3 fillers on the mechanical properties of the photopolymer resins were evaluated by Shore D hardness, tensile strength, and flexural strength tests. Moreover, the printing accuracy was assessed by the root-mean-square error (RMS) analysis. The results showed that the mechanical properties of the photopolymer resins were significantly improved when loaded with silanized nano-Al 2 O 3 fillers. The highest values were observed in the resin with 4 wt% filler content, improving hardness, tensile strength, and flexural strength by 11.7%, 31.1%, and 39.9%, respectively. For printing accuracy, loading 2 wt% and 4 wt% fillers did not influence the printing accuracy significantly. However, the incorporation of 6 wt% fillers compromised the printing accuracy. Within the limits, this study has demonstrated that the incorporation of silanized nano-Al 2 O 3 fillers can enhance the mechanical performance of photopolymer resins, indicating the potential of this material for improved quality of 3D printing dental applications.","PeriodicalId":18530,"journal":{"name":"Materials Research Express","volume":"12 8","pages":"085401-085401"},"PeriodicalIF":0.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147334180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
