Large-area fabrication of α-FAPbI₃ perovskite solar modules (PSMs) faces challenges in achieving uniform crystallinity and minimizing grain boundary defects. Herenin, a CsPbBr₃ seed layer was introduced onto the NiOx hole transport layer (HTL) via vacuum evaporation prior to perovskite film deposition using a vapor-blade coating method. Synchrotron-based in situ GIWAXS analysis revealed that the CsPbBr₃ seed layer effectively modulates the crystallization kinetics of PbI₂, facilitating the transition from δ-phase to α-phase perovskite and yielding films with superior crystallinity, grain size, and structural orientation. This seed layer also enhances the conductivity of NiOx, improves charge transport efficiency, and reduces recombination losses. As a result, large-area PSMs (active area: 61.56 cm²) incorporating the CsPbBr₃ seed layer achieved a power conversion efficiency (PCE) of 20.02%, compared to 17.62% for pristine devices. Additionally, these encapsulated modules exhibited excellent ambient stability, maintaining over 80% of their initial performance after 1100 hours under 60% relative humidity. This study highlights the potential of CsPbBr₃ seed layer engineering as a scalable and effective strategy for industrial production of high-efficiency, stable perovskite solar modules. © 2024, The Authors.

Electric manipulation of skyrmions in two-dimensional (2D) magnetic materials has garnered significant attention due to the potential in energy-efficient spintronic devices. In this work, using first-principles calculations and Monte Carlo simulations, we report the electric-field-tunable magnetic skyrmions in MnIn2Te4 monolayer. By adjusting the magnetic parameters, including the Heisenberg exchange interaction, Dzyaloshinskii-Moriya interaction, and magnetic anisotropy, through applying an electric field, the formation or annihilation of skyrmions can be achieved. Our work suggests a platform for experimental realization of the electric-field-tunable magnetic skyrmions in 2D magnets.

Additional depth information benefits the performance of tracking methods in the complex scenarios characterized by background clutter and occlusion;thus, the visual object tracking (VOT) using RGB-D videos has been widely discussed. However, the existing RGBD trackers neglect long-range interactive information between RGB and depth videos, limiting the further improvement. In this study, two transformer-based modules are proposed to mine the interactive information between two modalities and improve the RGB-D tracker's performance based on the enhanced features of the learned interactive information. A multi-modal feature enhancement (MFE) module combining the intra and inter information from the RGB and depth features is proposed. In addition, a multi-model fusion module, which integrates interactive information across tokens in the two modalities in the fused feature, is introduced. Building upon these modules, a new RGB-D object tracking method, RDT-TEF, is proposed. The comprehensive experiments considered three object tracking datasets, i.e., CDTB, DepthTrack and VOT-RGBD2022. The results indicate that the proposed tracker achieves better performance. © 2025 Elsevier B.V.

All-solid-state lithium batteries (ASSLBs) using solid polymer electrolytes (SPEs) are believed to be future next generation batteries aiming to replace high-risk traditional batteries using liquid electrolytes, which have a wide application range in portable electronic devices, portable power supplies, and especially in electric vehicles. Nevertheless, ASSLBs still face some limitations due to the low ionic conductivity of SSEs at room temperature and poor contact interface electrode/electrolyte, which can be solved by suitable strategies. Moreover, the appearance of SPEs can overcome the electrolyte leakage and flammability problems in conventional lithium-ion batteries. Currently, the discovery of metal-organic frameworks-incorporated composite solid polymer electrolytes (MOFs-SPEs) made from metal-organic frameworks (MOFs) and solid polymer electrolytes (SPEs) brings an extraordinary strategy to obtain uniform SSEs-type, ionic conductivity enhancement and improve contact interface electrode/electrolyte. Herein, the updates of current studies about metal-organic frameworks-incorporated composite solid polymer electrolytes are discussed in this mini-review. © 2023, The Authors. All rights reserved.

There is abundance of resume builder tools used to design the resume of the job seeker in the simplest way but still their resume cannot get shortlisted. By keeping this in mind so many professionals are still working on it to build the resume in the smartest way. In our proposed system, we have designed a prototype which uses the voice of the jobseeker. We have proposed a desktop application in which user is not responsible for resume format rather the application interacts with user like an assistant and collects the data from the user using voice. Our tool is based on Speech-To-Text (STT) and Text-To-Speech (TTS) and other APIs which we will discuss in the paper.

A comprehensive comparison of energy from waste (EfW) technologies is essential for guiding sustainable development. Our study examined eight EfW scenarios, including five gasification-based, one incineration-based, and two pyrolysis-based configurations, designed to produce syngas, electricity, hydrogen, methanol, and gasoline from municipal solid waste. We performed heat integration to minimize the utility demand for each scenario before conducting a techno-economic analysis (TEA) and life-cycle assessment (LCA). Because of the heat integration, the heating requirements were completely offset in all scenarios, and the cooling requirements significantly dropped. As a result of TEA, the total costs of the gasification-based scenarios ranged between 111.2 and 164.7 MMUSD/year and the pyrolysis-based scenarios exhibited the highest costs with 176.7 and 182.8 MMUSD/year. Conversely, the incineration-based scenario presented the lowest cost at 82.0 MMUSD/year. The minimum selling prices (MSP) of syngas, hydrogen, and methanol produced by gasification were 0.26, 1.68, and 0.35 USD/kg, respectively. The MSPs of electricity from lowest to highest are as follows: incineration (₵7.81/kWh), gasification (₵9.41/kWh), and pyrolysis (₵14.5/kWh). However, the pyrolysis-based scenario had a lower gasoline MSP ($2.70/gal) than the gasification-based scenario ($3.05/gal), demonstrating price competitiveness considering the market range of $2.5–3.1/gal. In addition, in conjunction with LCA, sensitivity analyses were performed to assess the impacts of economic parameters, technical parameters, plant capacity, and subsidies on the economics, offering valuable insights toward sustainability. © 2025 Elsevier Ltd

Expanded graphite (EG) has promising applications in field emission due to its high conductivity, thermal stability and low cost. In this paper, the field emission performance of EG is modulated by introducing hole defects through partial air oxidation. First, EG was prepared by electrochemical intercalation and microwave-assisted expansion methods. Subsequently, EG was heat treated in air at different temperatures to obtain holey expanded graphite (HEG). Finally, bulk HEG cathodes were prepared by the cold pressing method and the effect of holes on the field emission performance was investigated. The results showed that the conductivity and tensile properties of EG were significantly improved after heat treatment. Optimal heat treatment parameters were obtained at 400°C in an air atmosphere. The turn-on field (at 1 mA/cm2) and threshold field (at 10 mA/cm2) were 3.01 V/μm and 3.42 V/μm, respectively, with a maximum current density of 1359.17 mA/cm2 (at 5.83 V/μm) and a maximum field enhancement factor of 2407. The voltage fluctuation is only 1.1% over 24 h at 3 mA @ 440.33 mA/cm2, indicating good emission stability and lifespan. © 2024, The Authors. All rights reserved.

Organic solar cells (OSCs) are regarded as one of the most promising flexible power sources due to their lightweight and flexible properties, with the improvement of photovoltaic and mechanical performance. To improve the current density and power conversion efficiency (PCE), mPh4F-TS (TS) and PYSe2F-T (PA) are introduced into the binary host, PM6/mPh4F-TT (PM6/TT) as third components. It is demonstrated that the corresponding ternary devices, in both rigid and flexible devices, achieved superior efficiencies (19.6%/17.7% for PM6/TT+TS, and 19.2%/17.4% for PM6/TT+PA) outperform the binary counterparts (18.3%/16.4%). However, distinct differences in mechanical performance are observed between the polymer acceptor (PA) and small-molecular acceptor (TS). The PM6/TT+PA significantly improved the mechanical stability of flexible devices with a lower elastic modulus of 3.6 GPa, while the PM6/TT+TS resulted in the opposite effect with a higher elastic modulus of 5.5 GPa. Through in-depth investigation, a clear correlation between the elastic modulus, crack density, and mechanical stability of the active layer blends is successfully established, revealing the key role of reducing the elastic modulus in enhancing the mechanical stability of flexible OSCs. This study provides important guidance for the development of flexible photovoltaic devices with both high efficiency and mechanical robustness. © 2025 The Author(s).
