Herein, a type of BaTiO₃@MnO₂-based Z-scheme nano-heterojunction has been conjugated to doxorubicin-loaded carbon nanotubes to form functionalized hybrid nanocomposites for O₂-independent and TME-modulating combinational tumor therapy. The existences of BaTiO₃ and MnO₂ afford a built-in microelectric field which induces band tilting to effectively transfer electrons with a Z-scheme track, prolonged the electron–hole separation lifetime, and maintained strong redox potentials for hydrolysis and abundant reactive oxygen species generation. The in vivo experiments prove that nano-heterojunctions actively accumulate at the tumor after intravenous injection and demonstrate a glutathione-responsive behavior to impair tumor anti-oxidant and enhance ROS contents. It was also noted that the ultrasound-mediated treatment in association with nano-heterojunctions showed a superior O₂-independent tumor elimination (up to 90%) in company with dramatic recruitments of CD4⁺ and CD8⁺ T cells. Therefore, this study has validated the BaTiO₃@MnO₂-based Z-scheme nano-heterojunctions with tumor therapeutic interference in a drug-device-field integration manner and highlighted their promising utilities for modulating the tumor microenvironment and overcoming the O₂ dependence for an efficacious tumor therapy in live animals.</p></div>","PeriodicalId":7220,"journal":{"name":"Advanced Composites and Hybrid Materials","volume":"8 1","pages":""},"PeriodicalIF":23.2,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142859544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most polyimide-based TENGs have the disadvantages of poor air permeability and poor softness. In this study, a core–shell yarn with good air permeability, softness, and high electric output performance was successfully prepared by conjugate electrospinning. FEP-doped FPI and nickel-plated aramid yarn were employed as the shell and core materials, respectively. Due to the unique hierarchical porous structure and fluorinated functional group modification, the yarns exhibit excellent output performance (maximum open-circuit voltage is 22.7 V per length of 10 cm) compared to traditional polyimide yarns. The textile woven with this yarn has good high-temperature resistance, antifouling, waterproof, and self-cleaning performance, and still maintains an output performance of about 80% under 99% relative humidity. Moreover, this textile-based TENG has no significant attenuation after 10,000 cycles, showing good stability and durability. Finally, the TENG based on the intelligent fire suit is designed, which can be used for the movement and position monitoring of firefighters in high-temperature and high-humidity environments. This fluorinated polyimide yarn prepared in this study provides a promising solution for the development of self-powered sensors capable of monitoring the movement status and position of firefighters in high-temperature and high-humidity environments.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"22 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142866975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, high-quality <i>a</i>-axis oriented SnSe thin films were deposited on quartz substrates by using magnetron sputtering. The substrate temperature was optimized to improve the crystallinity of the SnSe thin film, resulting in larger grain sizes, which subsequently contributes to the improved carrier mobility.

This requires that scraps be reused or repurposed effectively, even when the scraps are co-mingled and have higher costs for further sorting and separation. In this work, we explore an alloy design concept by creating a compositionally flexible domain that can recycle multiple alloy grades and yet maintain relatively consistent properties across chemical variations. This is demonstrated through the Fe-Cr-Ni-Mn system to identify compositionally flexible austenitic stainless steels (CF-ASS) and accommodate the recycling of mixed austenitic stainless steel scraps. Alloys within the nominal composition spaces exhibit relatively consistent mechanical properties and corrosion resistance despite significant variations in different alloy compositions. We illustrate how we can utilise the compositionally flexible austenitic stainless steels to recycle mixed 200 and 300-series stainless steel and ferronickel scraps, demonstrating its practical viability. While this demonstration focuses on the stainless steel system, the underlying principles can be extended to other systems related to mixed scrap recycling.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"268 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results revealed distinct differences between the CV and GCD curves generated by the simplified Randles model and the commonly reported RC circuit models. Specifically, the RC circuit model shows current saturation at high voltages, which does not match the observed linear-like upper region behavior in supercapacitor CV curves, while the simplified Randles circuit model can capture this behavior. Notably, the simplified Randles model exhibited a low root-mean-square error (RMSE) in fitting experimental data, indicating its reliability in representing the real supercapacitor system.

To do so researchers are in search of the prominent and efficient multifunctional electrode materials. Therefore, in this study we synthesized cauliflower-like nanoarchitectures of nickel-manganese layered double hydroxide (NiMn-LDH) on porous nickel foam (NF) via hydrothermal method. We thoroughly examined the influence of the Ni / Mn molar ratios on the structural, morphological, and electrochemical properties. Among all the studied NiMn-LHDs, the highest specific capacitance of 1005 F/g at a current density of 1 mA/cm² in 1 M KOH electrolyte is obtained by the sample Ni₇₅Mn₂₅-LDH. Additionally, it demonstrates long-term cycling stability of 3000 cycles (72.7 % capacity retention) with negligible capacity loss of 0.009 % in each cycle. Furthermore, Ni₇₅Mn₂₅-LDH exhibits excellent oxygen evolution reaction characteristic with lowest overpotential of 296 mV at a current density of 10 mA/cm² and a Tafel slope of 86 mV/dec demonstrating favorable reaction kinetics. The electrode also maintained excellent electrochemical stability under continuous operation of the OER for over 50 h with minimal increase of overpotential.

While metal cation-binding sites on surfaces have been shown to provide a basis for the design of chemoresponsive LCs, the cations have been found to dissociate from the surfaces and dissolve slowly into LCs, resulting in time-dependent changes in the properties of LC–solid interfaces (which impacts the reliability of devices incorporating such surfaces). Here, we explore the use of surfaces comprising metal-coordinating polymers to minimize the dissolution of metal cations into LCs and characterize the impact of the interfacial environment created by the coordinating polymer on the ordering and time-dependent properties of LCs. In particular, by combining theoretical (electronic structure calculations) and experimental (polarization-modulation infrared reflection-adsorption spectroscopy) results, we determine that the pyridine groups of a thin film of poly(4-vinylpyridine<i>-co-</i>divinylbenzene) (P(4VP-<i>co</i>-DVB)) coordinate with Ni²⁺ when Ni(ClO₄)₂ is deposited onto the film. We provide evidence that the Ni²⁺-pyridine coordination weakens the binding of Ni²⁺ with 4′-<i>n</i>-pentyl-4-biphenylcarbonitrile (5CB), a room-temperature nematic LC, as compared to Ni(ClO₄)₂ supported on glass, although binding is still sufficiently strong to induce a homeotropic (perpendicular) orientation of the LC. Exposure of the 5CB films supported on Ni(ClO₄)₂-decorated P(4VP<i>-co-</i>DVB) substrates to parts-per-million vapor concentrations of dimethylmethylphosphonate (DMMP) was found to trigger orientational transitions (to planar (parallel) orientations) in the LC films. In contrast, 5CB supported on Ni(ClO₄)₂-decorated glass surfaces exhibited no response, even though displacement of 5CB by DMMP is predicted by computations to be thermodynamically favored in both cases. We propose that the distinct LC responses measured on glass and the coordinating polymer substrates are governed by the kinetics of displacement of 5CB by DMMP, a proposal that is supported by measurements performed with increasing temperature. Importantly, by using Ni²⁺ supported on P(4VP<i>-co-</i>DVB), we measured the ordering of 5CB to be stable and long-lived (&gt;7 days), in contrast to unstable LC ordering (&lt;14 h) when using Ni²⁺ supported on glass under dry conditions and at room temperature. We further demonstrate the stability of Ni(ClO₄)₂ supported on P(4VP<i>-co-</i>DVB) toward higher temperatures and humidity using E7 as the LC. Overall, these results demonstrate that metal-coordinating polymer films are a promising class of substrates for fabricating robust and long-lived chemoresponsive LCs.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"73 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
