Emerging applications of sustainable modified CdO/Ag-CdO NPs for electrochemical sensitive and selective detection of mercury (Hg) heavy metal.

The sensitivity of developed electrode has gained significant attention for potential energy storage and electrochemical sensor activities. The modified nano-CdO/Ag-CdO-carbon paste electrodes were developed for electrochemical detection of mercury (Hg) heavy metal. The synthesized samples were well characterized through PXRD (Powder X-ray diffraction), SEM-EDAX (Scanning Electron Microscopy-Energy Dispersive X-ray Analysis), XPS (X-ray photo-electron spectroscopy), FT-IR (Fourier transform Infra-Red), and UV-Visible spectroscopy.

Management of Patients With COVID-19 During the Pandemic: A Retrospective Cohort Study From a Tertiary Care Centre in Mumbai, India.

Introduction: We conducted the present analysis to understand the clinical outcomes in patients with COVID-19 infection and the factors associated with mortality over the one-and-a-half years of the pandemic in Mumbai, India.

Methods: This is a retrospective cohort study of 3561 COVID-19 patients admitted to a private tertiary care hospital in Mumbai, India. The main outcome variable for analysis was death (yes/no).

Social Drivers of Health and Firearm Storage Practices.

Importance: Understanding the primary social drivers of unsafe firearm storage practices is essential for preventing firearm-related injuries.

Objective: To examine household firearm ownership and storage practices, assess their association with social drivers of health (SDOH), and identify factors associated with unsafe storage practices among adult residents.

Design, Setting, And Participants: This cross-sectional analysis used 2022 Behavioral Risk Factor Surveillance System data from adults in 5 US states.

Impact of solid oxide FC-RFB and IPFC on a renewable multi-area power system using combined PI and FOPD controllers optimized by the African Vulture algorithm.

The expanding complexity of modern energy systems and the increasing integration of renewable sources make stable load frequency control (LFC) in interconnected power networks a continuing issue. Traditional controllers, such as proportional-integral (PI), proportional-integral-derivative (PID), and other subordinate control methods, frequently fail to control frequency adequately, especially in multi-source generating systems. Furthermore, standard optimization techniques may exhibit sluggish convergence and inefficient tuning, limiting their usefulness in real-time applications.

Green synthesis of neem extract and neem oil-based azadirachtin nanopesticides for fall Armyworm control and management.

The global spread of Fall Armyworm (FAW, Spodoptera frugiperda) has posed significant challenges to crop productivity and food security, with current pest management relying heavily on synthetic pesticides. This study explores the green synthesis of neem extract and neem oil-based Azadirachtin nanopesticides using cellulose acetate (CA) as a carrier polymer, focusing on their efficacy against FAW. The objective was to assess whether CA-NEP (neem extract nanopesticides) and CA-NOL (neem oil nanopesticide) formulations were effective at FAW control with minimal ecological impact.
