This paper proposes a scalable holistic day-ahead scheduling framework for EV charging by considering spatial-temporal properties of EVs for considering the amalgamation of Plug-in charging station (CS) and Battery Swapping Station (BSS). This work explores the factors for increasing the number of EVs charged and the profit of service providers through a novel algorithm including collaboration among aggregators. Using a 25-node transportation network, this framework is tested for realistic traffic scenarios using both non-collaborative and collaborative inter-aggregator schemes. The results under these scenarios prove the efficacy of the proposed framework in maximizing the scheduled vehicles and enhancement of the profit of aggregators against the non-collaborative scheme in each scenario. The proposed framework for day-ahead scheduling is thus capable of charging EVs with various energy demands during a day on its way at an appropriately assigned direct charging station or battery swapping station under a collaborative framework while incorporating realistic energy purchase for different traffic scenarios with cancellation penalties.

This study presents the synthesis and characterization of composite material comprised of NiFe2O4 and CuO. The preparation of this composites involves a facile and cost-effective co-precipitation method, followed by heat treatment. The aim of this study is to explore the potential of this composite material for various catalytic applications. The synthesized NiFe2O4/CuO composites were extensively characterized using various analytical techniques, including X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy (FTIR), impedance analyzer, UV-Visible spectroscopy (UV-Vis.), Brunner–Emmett–Teller (BET), and X-ray photoelectron spectroscopy (XPS). These characterizations revealed the successful formation of a nanocomposite material with a well-defined structure and identified the oxygen vacancies/defects in the samples which might result in enhanced photocatalytic efficiency. Photocatalytic activity of 0.5NiFe2O4/0.5CuO composite showed degradation of methylene blue dye by 96.15% in 120 min. This work is not only to understand the photocatalytic mechanism but also to develop effective catalysts for the degradation of harmful organic pollutants. [ABSTRACT FROM AUTHOR]

This article discusses an innovative technique for lung isolation in pediatric patients, which can be particularly useful in resource-limited settings. The technique involves using a combination of a rigid bronchoscope and a bougie as a substitute for a flexible bronchoscope. The authors describe a case in which this technique was successfully used in a 5-year-old patient undergoing thoracic surgery. However, they note that accurately predicting the length of the endotracheal tube (ETT) can be challenging, and confirmatory methods such as auscultation and lung ultrasound are necessary. The authors emphasize the importance of tailoring lung isolation techniques to the patient's profile and surgical requirements, while making the best use of available resources.
