Objective: here was investigated the potential of phytoconstituents as cinnamaldehyde and α-terpineol denture cleansers, which evaluated antifungal activity, also their effect on color change poly(methyl)methacrylate (PMMA). Methodology: Candida albicans biofilms were formed PMMA specimens exposed a 10 minutes daily treatment with (10 mg/ mL), NaCl 0.9%, NaClO 1%. Biofilms collected, then analy...

Effectiveness of disinfectant MA-T against Escherichia coli in various growth media was demonstrated by minimal inhibitory concentration (MIC). MIC (DM+1/100 volume LBG [Luria-Bertani medium with 0.4% glucose]) at pH 6.5 and 8.5 2.5 μg/mL, that 100%LBG 7.5 μg/mL 10 respectively. is not markedly affected organic materials or pH. HClO DM+1/100LBG 12.5 respectively, but rich (100%LBG) 300 500 indi...

Reclamation of printed circuit boards (PCBs) to recover metals is gaining growing attention due minerals being non-renewable resources. Currently, extraction from PCBs through an efficient and green method still under investigation. The present investigation concerns the recycling using hydrometallurgical processes. First, basic (Cu, Ni, Zn Fe) were separated a sulfuric acid solution at moderat...

Indonesian electricity supply is still dominated by coal-fired power plants (CPP) more than 50%. Water consumption for CPP in Indonesia reaches 222 million kL/year. Meanwhile, 10% of Indonesia's population predicted to experience a clean water crisis 2045. Most the consumed will be disposed as wastewater, such cooling tower blowdown and boiler blowdown. Boiler temperature relatively high. Thus,...

introduction estuaries are very important aquatic systems as they preserve the coastal biota, are considered as a highly dynamic ecotones that include the mixing or transition zone between freshwater saline water and are fairly appropriate places for living a wide variety of fauna and flora. an estuary is a semi- enclosed coastal area where freshwater from rivers and stream mixes with saltwater...

The effect of NaOH concentration values was observed on the cellulose structure Cladophora. Cladophora is synthesized from sp., a green alga that lives in aquatic environments (seawater and freshwater) soil surfaces (rocks wetlands). Cellulose synthesis carried out through processes bleaching, alkali hydrolysis, acid hydrolysis. Bleaching uses NaClO 2 , alkaline hydrolysis with varying concentr...

The carotenoids have vast medical, industrial, dietary, and pharmaceutical importance due to their provitamin A precursor, immunomodulator, antioxidant photoprotective activity. purpose of the research was optimize production using Rhodotorula mucilaginosa from artichoke agroindustrial waste as a low-cost substrate. artichokes bracts bleached by sodium hypochlorite (NaClO 2%) characterized thro...

Abstract The energy storage capability of the aqueous supercapacitors is mainly attributed to relatively low operating voltage device, as thermodynamic decomposition water 1.23 V. Therefore, extension working capacitor beyond electrolyte limit an important subject for development environmentally friendly devices. In this study, a commercial activated carbon (AC) and synthesized phosphorus-doped...

• Kinetic and stoichiometric studies on new catalysts in the chlorate process. Decomposition of hypochlorous acid at elevated temperature. YCl 3 catalyzes decomposition via formation O 2 . Y Te(OH) 6 slightly accelerate production. is a more active catalyst than but inferior compared to Cr(VI). By pursuing aim identifying types electrolytic production NaClO from NaCl (chlorate process), we repo...
