Abstract Semiconductor photocatalysis holds significant promise in addressing both environmental and energy challenges. However, a major hurdle photocatalytic processes remains the efficient separation of photoinduced charge carriers. In this study, TiO 2 nanorod arrays were employed by glancing angle deposition technique, onto which Ti 3 C T x MXene was deposited through spin-coating process. This hybrid approach aims to amplify efficacy arrays. Through photocurrent efficiency...
In recent years, inorganic lead-free perovskite materials have garnered attention for their non-toxicity, high carrier mobility, and strong light absorption capabilities, showing promising application prospects in photoelectric sensing. CsCu2I3 has been mentioned as one of the representatives a potential material short-wavelength optoelectronic devices. This study employs one-step chemical vapor deposition (CVD) process to fabricate thin films, which exhibit vibrant yellow emission at 560...
The state of health (SOH) and remaining useful life (RUL) lithium-ion batteries are crucial for management diagnosis. However, most data-driven estimation methods heavily rely on scarce labeled data, while traditional transfer learning faces challenges in handling domain shifts across various battery types. This paper proposes an enhanced vision-transformer integrating with semi-supervised SOH RUL batteries. A depth-wise separable convolutional is developed to extract local aging details...
Recently, there have been reports of lead halide perovskite-based sensors demonstrating their potential for gas sensing applications. However, the toxicity and instability lead-based perovskites limited This study addressed this issue by developing a H2S sensor based on lead-free CsCu2I3 film prepared using one-step CVD method. The demonstrated excellent properties, including high response selectivity toward H2S, even at low concentrations (0.2 ppm) room temperature. Furthermore, reasonable...

Abstract Rare-earth silicates are highly efficient materials for silicon-based light sources. Here we report a novel light-emitting device based on Ce 2 Si O 7 . Intense violet/blue electroluminescence was observed, with turn-on voltage of about 13 V. The emission is attributed to 4f–5d transitions the 3+ ions in , which formed by interfacial reaction CeO and Si. Electroluminescence photoluminescence mechanisms also discussed.
Compared to colloidal quantum dots, nanostructured multilayer films may also be a promising emission layer in future light-emitting diodes, due their excellent photoluminescence (PL), narrow full width at half-maximum (FWHM), and wide color gamut. In this paper, multilayer-structured deep-blue diodes (LEDs) were prepared, where ZnSe/ZnS act as the layer. The device showed good blue electroluminescence (EL) spectrum locating 448 nm with an FWHM of 31 nm. To improve performance device, effect...
The novel two-dimensional MXene material Ti 3 C 2 T x boasts advantages such as large specific surface area, good electrical conductivity, and high stability, making it suitable for the field of electrocatalysis.
Herein, we consider the heterojunction formation of two prototypical metal oxides: p-type NiO and n-type ZnO. Elementally abundant, low-cost oxide/oxide' heterojunctions are interest for UV optical sensing, gas photocatalysis, charge confinement layers, piezoelectric nanogenerators, flash memory devices.
