This paper presents a hydrothermal method for fabricating textured BaTiO3 (BTO) nanorod arrays with high crystallinity on fluorine-doped tin oxide (FTO) substrates by applying a polarization treatment to the samples to explore the feasibility of enhancing their piezoelectric properties. The preparation of highly textured BTO nanorod arrays using a two-step hydrothermal process was investigated in detail, including the spin-coating process for depositing the TiO2 seed layer, the influence of solution acidity on the hydrothermal synthesis of TiO2 nanorod arrays, and the formation mechanism of textured BTO nanostructures. The piezoelectric constants (d33) of the samples were determined using piezoresponse force microscopy. S-BTO(P), which has high crystallinity and preferential orientation, achieves a d33 as high as 85.4 p.m./V after poling, which is 3.2 times higher than that without textured structures and poling. Our findings revealed that chemically controlling and inducing a preferential orientation in the crystal structure of piezoelectric materials with a seed layer and specific hydrothermal conditions can significantly enhance their piezoelectric properties after poling, making them excellent candidates for piezoelectric devices. Especially, this study confirms that the piezoelectric-enhanced charge separation in poled BTO nanorod arrays enables efficient generation of reactive species under ultrasonication, leading to effective degradation of RhB. The strong piezocatalytic performance highlights the material's potential for practical applications in environmental pollutant removal. © 2025 Elsevier Ltd and Techna Group S.r.l.

Metal-semiconductor nanocomposites have emerged as a viable strategy for concurrently tailoring both thermal and electronic transport properties of established thermoelectric materials, ultimately achieving synergistic performance. In this investigation, a series of nanocomposite thin films were synthesized, embedding metallic cobalt telluride (CoTe2) nanophase within the nanocrystalline ternary skutterudite (Co(Ge1.22Sb0.22)Te1.58 or CGST) matrix. Our approach harnessed composition fluctuation-induced phase separation and in situ growth during thermal annealing to seamlessly integrate the metallic phase. The distinctive band structures of both materials have developed an ohmic-type contact characteristic at the interface, which raised carrier density considerably yet negligibly affected the mobility counterpart, leading to a substantial improvement in electrical conductivity. The intricate balance in transport properties is further influenced by the metallic CoTe2 phase’s role in diminishing lattice thermal conductivity. The presence of the metallic phase instigates enhanced phonon scattering at the interface boundaries. Consequently, a 2-fold enhancement in the thermoelectric figure of merit (zT ∼ 1.30) is attained with CGST-7 wt. % CoTe2 nanocomposite film at 655 K compared to that of pristine CGST. © 2024 The Authors.

Visually colorimetric sensing of hazardous metallic ions based on gold nanoparticles (AuNPs) has been considered a facile, on-site, and reliable monitoring route, yet the improvement of detection limit, as well as environmental pH tolerance, is still needed. Herein, we present an integrated probe design based on functionalizing AuNP cores with carbon quantum dots (CQD) as colorimetric probes for tracing Cu²⁺ ions with a limit of detection as low as 18.7 nM. Improved detection selectivity was elucidated with the reduction in thiol groups bound between CQD decorations and AuNP probes initiated by oxidation of Cu²⁺ ion analytes, thus separating crossly connected probes, depending on tracing Cu²⁺ concentrations. Moreover, distributed CQDs with negative potentials allowed the stabilization of dispersed AuNPs against re-aggregation, which caused the gradual morphological transition from aggregated features to dispersed states in microscopic view, and eventually, reflected the gradual color change from red to purple-red. The correlated practicality of colorimetric detection of the Cu²⁺ ion was further validated with sound-sensing selectivity, environmental pH resistance and tests on real samples. © 2024 The Royal Society of Chemistry

Metal-organic frameworks (MOFs) are promising candidates for membrane gas separation. MOF-based membranes include pure MOF membranes and MOF-based mixed matrix membranes (MMMs). This Perspective discusses the challenges for the next stage of the development of MOF-based membranes based on research conducted in the past decade. We focused on three major issues associated with pure MOF membranes. First, some MOF compounds have been overstudied, despite the availability of numerous MOFs. Second, gas adsorption and diffusion in MOFs are often independently investigated. The correlation between adsorption and diffusion has seldom been discussed. Third, we identify the importance of characterizing the gas distribution in MOFs to understand the structure-property relationships for gas adsorption and diffusion in MOF membranes. For MOF-based MMMs, engineering the MOF-polymer interface is essential for achieving the desired separation performance. Various approaches to modify the MOF surface or polymer molecular structure have been proposed to improve the MOF-polymer interface. Herein, we present defect engineering as a facile and efficient approach for engineering the MOF-polymer interfacial morphology and its extended application for various gas separations. © 2023 American Chemical Society.

Surfactant-assisted formation of robust p-Ag2O – n-BaTiO3 heterojunctions for visible-light photocatalytic applications

引用

Applied Surface science 2024年 655卷

This paper reports the use of microwave-assisted hydrothermal and precipitation approaches to prepare a composite from a polyethylene glycol (PEG − 10000) surfactant-assisted dispersion of p-Ag2O particles in conjunction with n-BaTiO3 (n-BTO) for use in visible-light photocatalytic applications. The conductivities of p-Ag2O and n-BTO were determined through Mott–Schottky measurements and verified using energy band diagrams. Various PEG − 10000-treated and untreated (1 − x)BTO − xAg2O (x ≈ 57.0, 63.0, and 75.0 mol%, determined using Rietveld refinement) composites were prepared. X-ray photoelectron spectroscopy was used to determine the valence states and binding energies of the constituent elements in the various composites. Scanning electron microscopy, transmission electron microscopy, and particle-size distribution measurements revealed that Ag2O is excellently dispersed in the PEG − 10000-treated composite, which exhibited a remarkable surface area (≈10 m2⋅g−1) and pore volume (≈0.05 cm3⋅g−1) at x ≈ 63.0 mol%. All composites exhibited effective and reliable visible-light energy-harvesting capabilities. The PEG − 10000-treated composite (x ≈ 63.0 mol%) exhibited the most promising rhodamine B photodegradability, attributable to the formation of abundant p − n junctions and the effective absorption of visible light. An energy-band diagram was constructed to elucidate the potential mechanism responsible for this remarkable activity. Under visible light, our samples outperformed other similar and representative literature-reported samples under solar light. © 2024 Elsevier B.V.

Nearly two billion air-conditioning (AC) units are currently being used for space cooling worldwide. The majority of these ACs use R134a as the working fluid, a greenhouse gas (GHG) with a global warming potential (GWP) of 1300 kg-CO2-eq. According to the rules set by the world environment safety organizations, the GWP of domestic air-conditioning systems must not exceed 750 kg-CO2-eq. Hence, the R134a must be phased out by 2025, and an alternative refrigerant with similar thermodynamic properties yet low GWP is required. Therefore, the authors have investigated several potential binary/ternary refrigerant blends in this study. Among the studied refrigerants, R445A, R30A, and NPB2 (newly proposed blend: 8% R152a + 92% R1234yf) can reduce 90–99% global warming impact (more than 200 million tonnes of CO2 emission equivalent) caused by the domestic air-conditioning systems every year. © 2023, The Institution of Engineers (India).

Spin- and valley flavor polarization plays a central role in the many-body physics of flat band graphene1–21, with fermi surface reconstructions—often accompanied by quantized anomalous Hall1–8 and superconducting state9–14—observed in a variety of experimental systems. Here we describe an optical technique that sensitively and selectively detects flavor textures via the exciton response of a proximal transition metal dichalcogenide layer. Through a systematic study of rhombohedral and rotationally faulted graphene bilayers and trilayers, we show that when the semiconducting dichalcogenide is in direct contact with the graphene, the exciton response is most sensitive to the large momentum rearrangement of the Fermi surface, providing information that is distinct from and complementary to electrical compressibility measurements. The wide-field imaging capability of optical probes allows us to obtain spatial maps of flavor orders with high throughput, and with broad temperature and device compatibility. Our work paves the way for optical probing and imaging of flavor orders in flat band graphene systems. Copyright © 2024, The Authors. All rights reserved.

Humans rely increasingly on sensors to address grand challenges and to improve quality of life in the era of digitalization and big data. For ubiquitous sensing, flexible sensors are developed to overcome the limitations of conventional rigid counterparts. Despite rapid advancement in bench-side research over the last decade, the market adoption of flexible sensors remains limited. To ease and to expedite their deployment, here, we identify bottlenecks hindering the maturation of flexible sensors and propose promising solutions. We first analyze continued...challenges in achieving satisfactory sensing performance for real-world applications and then summarize issues in compatible sensor-biology interfaces, followed by brief discussions on powering and connecting sensor networks. Issues en route to commercialization and for sustainable growth of the sector are also analyzed, highlighting environmental concerns and emphasizing nontechnical issues such as business, regulatory, and ethical considerations. Additionally, we look at future intelligent flexible sensors. In proposing a comprehensive roadmap, we hope to steer research efforts towards common goals and to guide coordinated development strategies from disparate communities. Through such collaborative

The recent development of perovskite-based lasers showcased the outstanding optical properties of the material such as high absorption coefficient and high quantum yield. The lasers were demonstrated in the form of nanowires and nanoplates, which are difficult to be integrated on a chip in the form of high-density arrays due to the difficulties in positioning them on the chip. The solution to this problem should be to use the well-known lithography process in the fabrication process of the lasers. In this work, we demonstrate several perovskite-based plasmonic lasers that were fabricated by using the lithographic in-mold patterning method that relies on the electron beam lithography process. The lasers utilized CsPbBr3 perovskite nanocrystals as the gain material and plasmonic distributed Bragg reflector grating structure as the optical feedback provider to achieve a low lasing threshold of 42.5 μJ/cm2 with a linewidth of 0.6 nm (FWHM) at room temperature. The use of the lithographic process in the fabrication of the lasers makes it possible to fabricate and integrate them on a chip in a relatively high-density manner, so that they can be used extensively in quantum optics and on-chip integrated photonics applications. © 2023 Author(s).

Breast cancer is a malignant tumor with a high mortality rate among women. Therefore, it is necessary to develop novel therapies to effectively treat this disease. In this study, iron selenide nanorods (FeSe2 NRs) were designed for use in magnetic hyperthermic, photothermal, and chemodynamic therapy (MHT/PTT/CDT) for breast cancer. To illustrate their efficacy, FeSe2 NRs were modified with the chemotherapeutic agent methotrexate (MTX). MTX-modified FeSe2 (FeSe2-MTX) exhibited excellent controlled drug release properties. Fe2+ released from FeSe2 NRs induced the release of •OH from H2O2 via a Fenton/Fenton-like reaction, enhancing the efficacy of CDT. Under alternating magnetic field (AMF) stimulation and 808 nm laser irradiation, FeSe2-MTX exerted potent hyperthermic and photothermal effects by suppressing tumor growth in a breast cancer nude mouse model. In addition, FeSe2 NRs can be used for magnetic resonance imaging in vivo by incorporating their superparamagnetic characteristics into a single nanomaterial. Overall, we presented a novel technique for the precise delivery of functional nanosystems to tumors that can enhance the efficacy of breast cancer treatment. © 2024 The Authors.
