The urgent need to address escalating environmental pollution and energy management challenges has underscored the importance of developing efficient, cost-effective, and multifunctional electrocatalysts. To address these issues, we developed an eco-friendly, cost-effective, and multifunctional electrocatalyst a solvothermal synthesis approach. Due to the merits of the ideal synthesis procedure, the FeCoHS@NF electrocatalyst exhibited multifunctional activities, like OER, HER, OWS, UOR, OUS, and overall alkaline seawater splitting, with required potentials of 1.

Herein, we demonstrated that a polycrystalline cobalt oxide/borate (CoO-Bo) hybrid catalyst prepared by coprecipitation followed a simple annealing process with a viable boron source of less hazardous ammonium borate, an efficient electrocatalyst for the oxygen evolution reaction (OER). The borate species in the crystalline cobalt oxide lattice provides a tunable polycrystalline morphology with a defect-rich lattice and numerous grain boundaries in the CoO-Bo hybrid electrocatalyst, which significantly boosts the OER activity compared to the crystalline counterparts of CoO and precious IrO in a harsh alkaline electrolyte (1 M KOH). The borate modulated CoO-Bo achieves a 10 mA/cm geometrical current density for the OER with a very low overpotential (η) of 271 mV and small Tafel slope of 34 mV dec, in an inert glassy carbon (GC) support, while only requiring η of 267 and 32 mV dec in a 3D nickel foam (NF) support at the same current density.

Allergic rhinitis and asthma are commonly coexisting conditions, significantly impacting patient health and quality of life. Despite their interrelation, diagnosing allergic rhinitis in patients with asthma remains challenging, leading to underdiagnosis and suboptimal management. The expert consensus engaged a modified Delphi method involving 29 experts including pulmonologists, ear, nose, and throat surgeons, and allergologists.

Introduction: Root canal retreatment is carried out in cases where previous endodontic therapies failed and involves the removal of root canal filling materials, followed by cleaning, shaping, and obturating of the canals.

Aims: : The objective of this study was to collect information regarding attitudes, methods, and materials employed during the non-surgical endodontic retreatment (NSER) by general dentists working in Sousse Governorate, Tunisia.

Materials And Methods: A descriptive cross-sectional survey was conducted among 147 general dentists working in the Sousse Governorate, Tunisia, from May to November 2021.

Article Synopsis
  • The study focuses on creating new electrochemical sensors using curcuminoids to detect environmental pollutants in water.
  • The first sensor, using curcumin-conjugated carbon nanotubes, effectively detected 1,4-dioxane with a low limit of detection (LOD) of 35.71 pM.
  • The second sensor employed bisdemethoxy curcumin analog quantum dots for hydrazine detection, achieving a LOD of 10 nM, demonstrating the potential of curcuminoids in developing sensitive, metal-free sensors.
