Smear layer removal and antimicrobial efficacy of chitosan as a root canal irrigant: a systematic review of in-vitro studies.

This systematic review was designed to answer the following question: Does chitosan provide better smear layer removal and antimicrobial efficacy than other root canal irrigants? A literature search was done using electronic databases PubMed, Scopus, Web of Science, Cochrane Library, EBSCO host, Grey Literature Report, and Open Grey from inception to June 18, 2024. The reference lists of included articles were also hand-searched. Two reviewers independently assessed the studies' eligibility based on the inclusion and exclusion criteria and performed data extraction.

Enhanced efficiency of photocatalytically synthesised Co/Co-incorporated CeO/SnO nanocomposite and supercapacitor studies.

The photochemical reduction approach, distilled HO with PrOH as the solvent medium, was used to create and characterise the conversion of Co to Co integrated on CeO/SnO. The PXRD, IR, SEM, HR-TEM, VSM, and XPS results show that the materials generated have appropriate crystallisation form and retain the hollow spherical structure of Co-CeO/SnO. The performance of several UV-light energetic photocatalysts and the reaction pathways for inorganic complex degradation are addressed, emphasising the main elements contributing to their mineralisation.

An integrated approach to remove endocrine-disrupting chemicals bisphenol and its analogues from the aqueous environment: a review.

Bisphenol A (BPA) is a well-known endocrine-disrupting chemical (EDC) used as a plastic enhancer in producing polycarbonate resins to manufacture hard plastics. Due to strict limitations on the manufacturing and utilization of BPA, several bisphenol substitutes, bisphenol F (BPF), bisphenol S (BPS), and bisphenol AF (BPAF), have been developed to replace it in various applications. Because of their widespread use in food containers, infant bottles, and reusable water bottles, bisphenols (BPs) have been identified in different environmental circumstances, including drinking water, seawater, industrial effluent, and endocrine systems such as human blood, urine, and breast milk.

Phthalates removal from wastewater by different methods - a review.

Phthalate esters are commonly used as plasticizers to improve the durability and workability of polymeric materials, locating and identifying them in various contexts has become a major challenge. Because of their ubiquitous use in plastic packaging and personal care items, as well as their tendency to leach out of these materials, phthalates have been detected in a variety of aquatic situations, including surface water, groundwater, drinking water, and wastewater. Phthalate esters have been shown to affect reproductive health and physical growth by disrupting the endocrine system.
