Residential communities increasingly adopt renewable energy sources (RES) to reduce energy costs. However, these sources are weather-dependent and unpredictable, posing challenges for reliable operations. Therefore, managing uncertainties in power supply has become an important research focus. These uncertainties directly affect the performance of microgrids. Energy storage systems are integral, enabling battery-backed supply for residential loads during unpredictable conditions. This paper presents an evidence-based fusion framework for accurate load and PV power forecasting in uncertain scenarios. Dempster-Shaffer's theory has been used to develop a fusion framework. In addition, electricity network modeling for a day-long electricity cost analysis of a residential community has been done in three scenarios. In scenario 1, the community power supply is connected to the grid; in Scenario 2, users have a PV system on their premises but no storage; and in Scenario 3, users have their own PV-integrated storage system. The electricity price for buying and selling energy from the grid is also assumed to be fixed. The primary objective of this framework is to minimize the operating cost under a set of different constraints. The results showed that the prediction performance of the proposed algorithm is better than others. Thus, under uncertainty, scenario 3 is more economical than the other two, and the total cost with the proposed algorithm is less than $0.705 in scenario 1 and less than $0.339 in scenario 2.

Hybrid material of surgical mask activated carbon (SMAC) and Fe2O3 (SMAC-Fe2O3) composite was prepared by simple co-precipitation method and used as potential material for the remediation of 2,4-dicholrophenol (2,4-DCP). The XRD patterns exhibited the presence of SMAC and Fe2O3, FTIR spectrum showed the FeO-carbon stretching at the wavenumber from 400 to 550 cm−1. UV–Vis DRS results showed the band gap was 1.97 eV and 2.05 eV for SMAC-Fe2O3 and Fe2O3, respectively. The SEM images revealed that the Fe2O3 doped onto the fiber morphology of SMAC. The outcomes of the BET examination exhibited a surface area of 195 m2/g and a pore volume of 0.2062 cm3/g for the SMAC/Fe2O3 composite. The batch mode study shows the maximum adsorption and photocatalytic degradation efficacies which were 97% and 78%, respectively. The experimental data was studied with both linear and nonlinear adsorption isotherm and kinetics models. The nonlinear Langmuir isotherm and pseudo-second-order kinetics (PSOK) models have well fit compared with other models. The Langmuir maximum adsorption capacity (qmax) was found 161.60 mg/g. Thermodynamic analysis shows that the 2,4-DCP adsorption onto SMAC-Fe2O3 was a spontaneous and exothermic process. The PSOK assumes that the adsorption process was chemisorption. The photocatalytic degradation rate constant of 2,4-DCP was calculated using pseudo-first-order kinetics (PFOK) and the rate constant for SMAC-Fe2O3 and Fe2O3 were 0.859 × 10−2 min−1 and 0.616 × 10−2 min−1, correspondingly. In addition, the obtained composite exhibited good reusability after a few cycles. These results confirmed that SMAC-Fe2O3 composite is an effective adsorbent and photocatalyst for removing 2,4-DCP pollutants. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.

Due to various physical or biochemical processes, the nature of polydimethylsiloxane (PDMS) could affect the sensitivity and accuracy of immunoassays performed in microfluidic channels. An appropriate PDMS membrane with high adsorption properties and low background noise allows more sensitive detection of biomarkers. Here, we explored the unusual correlation between membrane surface properties and the signal-to-noise ratio (SNR) of immunoassay, developed a microfluidic-based versatile point-of-care (MVP) detection system on PDMS membrane to simultaneously detect multiple vitamins from multiple human serums. Compared with conventional enzyme-linked immunosorbent assay (ELISA) and Roche electroluminescence method, the MVP detection system exhibits a lower consumption of sample and reagents (10 µL per test), a lower limit of detection (LOD: 6.15 ng/mL), a higher SNR (33.49 dB) and multiplexed ability (seven samples and two targets in one assay). Our MVP detection system can quantitatively detect folic acid (FA) and vitamin D3 (VD 3 ) from human serums and shows good consistency with ELISA and Roche electroluminescence methods. The R square values of FA and VD 3 detections are 0.94 and 0.91, respectively. The MVP system is more cost-effective than utilizing conventional methods for a single detection (about 0.04 USD for each target) because of the straightforward design of our detection instruments, their superior anti-interference capabilities, and the low cost of routine instrument maintenance.

As deep neural networks (DNNs) have advanced, high-quality pre-trained models have provided excellent feature extraction methods for embedding-based unsupervised anomaly detection (EUSAD). However, when calculating anomaly scores, common EUSAD models often rely on point-to-point distance computations between test features and reference features. This approach not only fails to fully utilize the carefully integrated reference feature library but may also increase pixel-level false positives due to the incorrect selection of reference points. To address this issue, this paper adopts the least squares method, evaluating anomalies by calculating the distance between test feature points and the reference feature plane. Experimental results demonstrate that this method not only performs well in global image detection but also significantly reduces pixel-level false positives, showing strong performance across many anomaly detection datasets. © 2025 SPIE.

Lithium argyrodites with high ionic conductivities are favorable solid electrolytes (SEs) for all-solid-state batteries (ASSBs). However, their low preparation efficiency and poor cycling performance hinder their large-scale applications. In this work, we demonstrate successful large-scale production (over 1 kg per batch for the first time) of Li5.5PS4.5Cl0.75Br0.75 (LPSCB) by fast dry mixing followed by annealing, which presents high room temperature ionic conductivities of 13 mS cm−1 for cold-pressed and 25 mS cm−1 for sintered pellets. Combining neutron powder diffraction and 6Li → 7Li tracer-exchange nuclear magnetic resonance (NMR) spectroscopy measurements, we show that intercage jumps frequently occur through the 48h-16e-48h pathway in LPSCB, promoting the overall lithium conduction. The assembled ASSBs using LPSCB and a LiNi0.83Co0.11Mn0.06O2 electrode can be cycled for over 2,500 cycles at a 0.5 C rate and 1,800 cycles at a 2 C rate without any capacity degradation. Our results will accelerate the commercialization of sulfide SE for ASSBs. © 2025 Elsevier Inc.
