title: The XFMP dataset for Explainable Fine-Grained Abnormal Behavior Recognition on Medical Personal Protective Equipment
title: The XFMP dataset for Explainable Fine-Grained Abnormal Behavior Recognition on Medical Personal Protective Equipment

description:  The XFMP dataset is designed for abnormal behavior recognition on medical personal protective equipment, which features fine-grained and explainable annotations. The proper use of medical personal protective equipment (MPPE) is critical for frontline healthcare workers (HCWs) to handle highly contagious diseases. Due to the complexity of PPE donning and doffing protocols, public health organizations typically recommend having trained observers monitor the entire PPE donning and doffing process, preventing self-contamination and transmission. However, the high costs of manual monitoring impede the implementation of this practice, which makes AI-assisted PPE monitoring highly valuable. To address this, we propose an explainable and fine-grained dataset for MPPE doffing monitoring called the XFMP dataset. The dataset contains 3596 expert-annotated samples over three sub-tasks: doffing stage classification (DSC), abnormal action recognition (AAR), and critical region localization (CRL).

title: Study of poly-disperse aerosols deposition in turbulent flow with different Reynolds numbers
title: Study of poly-disperse aerosols deposition in turbulent flow with different Reynolds numbers

description: The turbulent deposition mechanism is one of the main mechanisms of aerosol deposition in nuclear power plant tubes. An experimental study of poly-disperse aerosol deposition in a horizontal tube is conducted, where the nominal Reynolds number (Re) is in a range of 3600–200,000. The aerosol deposition velocity first increases and then decreases with the increase of Res, and at high Re, particle rebound occurs during aerosol deposition in the tube. When the Re is low, the aerosol deposition velocity increases with the increase of aerosol diameter. When the Re is greater than 60,000, the deposition velocity first increases and then decreases with the increase of aerosol diameter due to particle surface rebound. A new aerosol deposition model has been developed by establishing the energy conservation equation of the rebounded particles in the viscous sublayer. The calculated results of the new model are in good agreement with these experimental results, and the error between the aerosol deposition velocity calculated by the model and experimental results is between −60% and 150%.

title: Plasmon-Enhanced All Organic Ultraviolet Photodetectors with High Sensitivity and Long-Term Stability

description: All-organic ultraviolet (UV) photodetectors have gained significant attention due to their advantages of low-cost fabrication, flexibility, and ease of processing. However, challenges such as limited photoresponsivity, stability, and weak light detection have hindered their practical application. In this study, we report the fabrication of Au nanoparticles (NPs) on ITO glass substrates via one-step annealing, followed by the construction of Au NPs/Ph-BTBT-12/C60 UV photodetectors. The incorporation of Au NPs results in an absorption enhancement of approximately 443.2%, , significantly improving the photoresponsivity performance of the device from 69.6 μA/W to 413.1 μA/W. The device demonstrates photoresponsivity across the solar-blind UV spectrum and partial visible light, while efficiently detecting weak light at intensities as low as 0.01 mW/cm². Notably, the photodetector retains its performance after two months, exhibiting excellent stability. Finite element method simulations reveal that the different morphologies of the Au NPs lead to significant electric field enhancement. Furthermore, surface-enhanced Raman scattering (SERS) from the organic semiconductor C60 was achieved by thermal annealing of the Au NP arrays. These findings offer valuable strategies for improving the performance and durability of organic UV photodetectors.

title: Preparation of calcium carbonate with microstructure and nanostructure from carbide slag for CO2 sequestration by using recyclable ammonium chloride
title: Preparation of calcium carbonate with microstructure and nanostructure from carbide slag for CO2 sequestration by using recyclable ammonium chloride

description: Based on the composition characteristics of carbide slag and the application of polyvinyl chloride, a method of preparing calcium carbonate with microstructure and nanostructure by using carbide slag as a raw material and ammonium chloride as a leaching agent was proposed. The factors for the preparation of calcium carbonate and the effects of different conditions on the crystal phase, grain size, and morphology of calcium carbonate were systematically studied. The results showed that the nanosized calcium carbonate was prepared at 60 mL/min, 25 °C, no additional ammonia, and 60 min. The product of spherical vaterite was in accordance with the relevant standards for the industrial precipitation of calcium carbonate. Moreover, the reuse of carbonation filtrate was realized. The crystal phase, grain size, and morphology of the carbonation product could be controlled by adjusting the reaction conditions. The manuscript provided a new idea for resource utilization of carbide slag and preparing nanocalcium carbonate.

title: Self-cleaning effect and secondary swirling clean gas for suppressing particle deposition on vortex finder of gas cyclones
title: Self-cleaning effect and secondary swirling clean gas for suppressing particle deposition on vortex finder of gas cyclones

description: In order to suppressing the particle deposition on vortex finder, a series of gas cyclones with the secondary swirling clean gas were developed inspired by the gas purge effect. Effects of the width and extension length of the flow channel as well as the secondary inlet velocity and running time on the particle deposition pattern, the deposited particle mass and the cyclones’ performance were experimentally investigated, respectively. The results show that the ultrafine particles (Stokes number Stk &lt; 0.0358) are mainly loose deposited on the walls under the secondary gas. Compare to the conventional cyclone with single tangential inlet, the total deposited particle mass of the improved cyclone has a maximum reduction more than 60%, and the collecting efficiency is increased up to 97.5% under the basically same pressure drop. The corresponding no-deposition area is increased by about 13%, and remains constant in spite of extending the running time. Moreover, an interesting phenomenon named “self-cleaning effect” of the vortex finder was captured for the gas cyclones, and mechanism of the secondary clean gas on the particle deposition is preliminarily analyzed. The results can deepen the understanding of the particle deposition on the vortex finder and guide the design of the anti-coking gas cyclones.

title: Data driven reduced modeling for fluidized bed with immersed tubes based on PCA and Bi-LSTM neural networks

description: The fast and accurate reduced-order modeling of fluidized beds is a challenging task in the field of fluid dynamics, owing to their high dimensionality and nonlinear dynamic behavior. In this study, a nonintrusive reduced order modeling method, the reduced order model based on principal component analysis and bidirectional long short-term memory networks (PBLSTM ROM), was developed to capture complex spatio-temporal dynamics of fluidized beds. By combining principal component analysis and Bidirectional long- short-term memory networks, the PBLSTM ROM effectively extracted dynamic evolution information without any prior knowledge of governing equations, enabling reduced-order modeling of unsteady flow fields. The PBLSTM ROM was validated using the solid volume fraction and gas velocity flow fields of a fluidized bed with immersed tubes, showing superior performance over both the PLSTM and PANN ROMs in accurately capturing temporal changes in the fluidization fields, especially in the region near immersed tubes where severe fluctuations appear. Moreover, the PBLSTM ROM improved the simulation speed by five orders of magnitude compared to traditional computational fluid dynamics simulations. These findings suggest that the PBLSTM ROM presents a promising approach for analyzing the complex fluid flows in engineering practice.

title: Synthesis of core-shell nanostructured SiO2/TiO2 photocatalysts via atomic layer deposition in a fluidized bed with central tube
title: Synthesis of core-shell nanostructured SiO2/TiO2 photocatalysts via atomic layer deposition in a fluidized bed with central tube

description: Fluidized bed atomic layer deposition is an efficient technique for particle coating with precise control over the film thickness and uniformity at the sub-nanoscale. In this study, a fluidized bed with a central tube is designed, where the central tube has two roles: improve fluidization and deliver precursors separately. The synthesis of core-shell structured SiO2/TiO2 nanoparticle catalysts for photodegradation of tetracycline hydrochloride (TC) is carried out using TiCl4 and H2O as precursors at 180 °C under atmospheric pressure. Under the combination of vibration and central tube, the segregation of agglomerate size along the bed height is weakened, and the prepared SiO2/TiO2 nanoparticles show excellent photocatalytic degradation performance: the degradation efficiency on TC is 96% under 300 W xenon lamp irradiation for 60 min. The mechanism of enhanced photocatalytic activity is due to the Ti-O-Si bonds generated at the interface, which increase the ability to absorb sunlight and accelerate the separation of holes and electrons.
