Ni-Zn/CeO nanocomposites for enhanced adsorptive removal of 4-chlorophenol.

Chlorophenols are one of the major organic pollutants responsible for the contamination of water bodies. This study explores the application of Ni-Zn/CeO nanocomposites, synthesized via the aqueous co-precipitation method, as effective adsorbents for the 4-chlorophenol removal from aqueous solutions. The nanocomposites' chemical and structural characteristics were assessed using different physical characterization methods, viz.

"Adsorptive removal of Congo Red dye from its aqueous solution by Ag-Cu-CeO nanocomposites: Adsorption kinetics, isotherms, and thermodynamics".

Eliminating synthetic dyes and organic contaminants from water is crucial for safeguarding human health and preserving the environment. In this study, we explored the effectiveness of Ag-Cu-CeO nanocomposites as adsorbents to remove Congo Red dye from water. Three compositions of Ag-Cu-CeO nanocomposites (10:20:70, 15:15:70, and 20:10:70) have been synthesized by the aqueous coprecipitation method.

Alternative root canal filling materials to zinc oxide eugenol in primary teeth: a systematic review of the literature.

Purpose: The aim of this review was to compare the currently available root canal filling materials for primary teeth to zinc oxide eugenol (ZOE) to find a suitable alternative. The search question was: which root canal filling materials used in pulpectomy for primary teeth give better clinical and radiographic success rates than ZOE?

Methods: A systematic search was conducted using five databases, namely Cochrane central register of controlled trials (CENTRAL), MEDLINE via PubMed, Science Direct, Scopus and EBSCOhost using a selection of "MeSH terms". The "Modified Jadad Scale" was used for the methodology assessment of the included studies.

Understanding the Role of (W, Mo, Sb) Dopants in the Catalyst Evolution and Activity Enhancement of Co O during Water Electrolysis via In Situ Spectroelectrochemical Techniques.

Unlocking the potential of the hydrogen economy is dependent on achieving green hydrogen (H ) production at competitive costs. Engineering highly active and durable catalysts for both oxygen and hydrogen evolution reactions (OER and HER) from earth-abundant elements is key to decreasing costs of electrolysis, a carbon-free route for H production. Here, a scalable strategy to prepare doped cobalt oxide (Co O ) electrocatalysts with ultralow loading, disclosing the role of tungsten (W), molybdenum (Mo), and antimony (Sb) dopants in enhancing OER/HER activity in alkaline conditions, is reported.
