In this study, gas evolution in a vertical electrochemical cell is investigated numerically with a modified two-fluid model. The mathematical model involves solution of separate transport equation for the gas and liquid phases with an allowance to inter-phase transfer of mass and momentum. The governing equations are discreted via the finite volume technique and then are solved by ...

INTRODUCTION The purpose of this in vitro study was to assess the antifungal activity of final canal rinse with either three concentrations of sodium hypochlorite (NaOCl) (0.5, 2.6 and 6%), two concentrations of chlorhexidine (CHX) (2% and 0.2%), MTAD, Tetraclean, Hypoclean and Chlor-Xtra on Candida albicans (C. albicans) in a human tooth model. METHODS AND MATERIALS Two hundred and thirty fi...

The increasing share of variable renewable energies in the power grid is an incentive to explore demand response strategies. Chlor-alkali processes are high potential candidates, according previous publications. Within Germany’s chemical industry, chlorine production accounts for approximately 20% electricity use and could play a significant role stabilisation on consumer end. This study focuse...

Antibiotic residues have been found in environmental samples, such as water, soil, and even food, usually come from wastewater, presenting human health risks. This study aimed to improve the elimination of antibiotics tetracycline (Tet) chloramphenicol (Chlor) by modifying three factors: contact time (3–7 days), plant biomass (10–14 g), antibiotic concentration (5–15 mg/L Tet 10–20 Chlor). An a...
