Objectives. To evaluate crosslink densities of two bulk fill composite resins and determine if the used Food Simulating Organic Solvent (FSOS) affected them. Methods. Forty specimens were prepared from SureFill and SonicFill bulk fill composite resins, 20 each. All specimens were stored dry for 24 h. Each group was divided into 2 subgroups: stored in ethanol (E) 75% or in methyl ethyl ketone (M...

Compounds interaction on biodegradation of toluene and methyl ethyl ketone (MEK) mixtures in a composite bead biofilter was investigated. The biodegradation rate of two compounds in the exponential growth phase and stationary phase for the single compound and two compounds mixing systems was determined. For the single compound system, the biodegradation rate of two compounds in the microbial gr...

Changing urban emission landscapes and increasing population make it imperative to understand the driving forces for air quality in growing areas. Recent field studies an industrial area Houston a semiurban San Antonio reveal unique signatures these two Texas cities. A comparison of benzene, toluene, xylenes, isoprene, methyl ethyl ketone (MEK) was conducted locations previous other megacities....

This study presents synthesis results of catalysts made perovskite-like oxide La2-xSrxCuO4 (x=0.0, 0.5, 1.0) using the citrate method and crystallisation at 800°C. The structure was characterised by X-ray diffraction (XRD). catalyst activity enhanced with gold (Au) platinum (Pt). Au mounted on sol-gel method. perovskite LaMnO3/LaCuO3 evaluated complete oxidation volatile hydrocarbons (HCs) in a...

Polyols can be synthesized from carbohydrates in bioor chemo-catalytic way. The conversion of polyols with two hydroxyl groups in 1,4-positions, for example 1,4-butanediol, results in furan derivatives. In contrast, during the dehydration of diols with two vicinal hydroxyl groups, for example, 1,2-propaneand 1,2-butanediol, aldehydes or ketones are formed [1] . This will be presented exemplaril...

The plastic hardener methyl ethyl ketone peroxide is unstable peroxide that releases free oxygen radicals. Ingestion of this compound induces widespread liver necrosis, severe metabolic acidosis, corrosive esophagitis and gastritis, that is often fatal. A 49-year-old man unintentionally ingested approximately 100 mL (55%) of this compound in solution, which was purchased as plastic hardener. De...

The rapid growth of the semiconductor industry has made significant strides in addressing clean energy concerns. However, there are still unresolved issues related to waste solvents. One promising approach tackle these challenges is through pyrolysis. This study selected methyl ethyl ketone (MEK) from industrial sector as feedstock for pyrolysis, resulting various residual products such fixed c...
