Development of a novel and robust CuO-CoO@Biochar nanocomposite using Terminalia chebula leaf extract for reduction of nitro compounds and photodegradation of single and binary mixture of organic contaminants.
Environ Sci Pollut Res Int
December 2024
Department of Chemistry, National Institute of Technology, Silchar, 788010, Assam, India.
In this work, Terminalia chebula leaf extract was used to synthesize CuO-CoO nanoparticles, which were then embedded in a rice straw biochar. This new biochar-based nano-catalyst is used to photocatalytically degrade a variety of dyes (Eosin Y, Trypan Blue, Crystal Violet, Methylene Blue, Brilliant Green), as well as a binary mixture of Eosin Y and Trypan Blue dyes. It is also used for the catalytic reduction of nitro compounds (4-NP, 3-NP, and Picric acid).

Introduction: Nurses require good knowledge about professional values to provide quality nursing care. Implementing professional values in clinical areas improves the quality of patients care. Even though applying professional values had significant impact on the continuity and quality of nursing care, there is scarcity of study on professional values in Ethiopia.

Generative models, especially diffusion models, have gained traction in image generation for their high-quality image synthesis, surpassing generative adversarial networks (GANs). They have shown to excel in anomaly detection by modeling healthy reference data for scoring anomalies. However, one major disadvantage of these models is its sampling speed, which so far has made it unsuitable for use in time-sensitive scenarios.

It has been argued that realistic models of (singularity-free) black holes (BHs) embedded within an expanding Universe are coupled to the large-scale cosmological dynamics, with striking consequences, including pure cosmological growth of BH masses. In this pilot study, we examine the consequences of this growth for the stochastic gravitational wave background (SGWB) produced by inspiraling supermassive cosmologically coupled BHs. We show that the predicted SGWB amplitude is enhanced relative to the standard uncoupled case, while maintaining the [Formula: see text] frequency scaling of the spectral energy density.

The evidence for the association between the triglyceride (TG) to high-density lipoprotein cholesterol (HDL-c) ratio and the risk of developing microalbuminuria is still limited in the Chinese population. Therefore, our research will endeavor to explore the relationship between the two. The cross-sectional survey enrolled 32,877 general population from eight regional centers in China.
