Acute exacerbation of idiopathic pulmonary fibrosis after inhalation of a water repellent

open access: yesInternational Journal of Occupational Medicine and Environmental Health, 2015
The natural course of idiopathic pulmonary fibrosis (IPF) is unpredictable at the time of diagnosis. Some patients may experience episodes of acute respiratory worsening that have been termed acute exacerbations.

Biogas Upgrading Approaches with Special Focus on Siloxane Removal—A Review

open access: yesEnergies, 2020
Biogas, a product of anaerobic digestion process that consists mainly of methane and carbon dioxide is a suitable alternative fuel if unwanted impurities are removed as they have a negative impact on the equipment.

Thermal Stability and Thermodynamic Performances of Pure Siloxanes and Their Mixtures in Organic Rankine Cycles

open access: yesEnergies, 2022
Organic Rankine cycles are often the best solution for the conversion of thermal energy. The many working fluids include silicon oils. One crucial issue that determines the choice of a working fluid is its thermochemical stability, as this sets a limit ...

Bioaccumulation of Linear Siloxanes in Fish

open access: yesEnvironmental Toxicology and Chemistry, 2023
Abstract The bioaccumulation behavior, including the uptake, internal distribution, depuration, and biotransformation rates, of three widely used linear methyl-siloxanes was investigated in rainbow trout. Dietary uptake efficiencies of octamethyltrisiloxane (L3), decamethyltetrasiloxane (L4), and dodecamethylpentasiloxane (L5) were 15 ...

Multi-matrix contamination by cyclic and linear siloxanes in a highly industrialized estuarine environment of Korea: source identification, seasonal variation, and bioaccumulation potential

open access: yesFrontiers in Marine Science
Cyclic and linear siloxanes are widely used in personal care, industrial, and consumer products. To better understand their fate and ecological risks in estuarine environments, this study investigated spatial distribution, seasonal variations, and the ...

Siloxane Modification of Bismaleimide Resins [PDF]

open access: yesPolymer Journal, 1987
Polybismaleimides have high thermostability, but they are very brittle materials. Introduction of spacers such as aromatic diamines by addition onto the maleimide double bonds gives after crosslinking of the remaining double bonds, a polyaminobismaleimide network with greatly reduced brittleness.

Factors determining contamination and time trends in cyclic and linear siloxanes in sediments from an industrialized lake in Korea

open access: yesEcotoxicology and Environmental Safety
Siloxanes, widely used in various consumer and industrial products, are emerging concerns of contaminants. Despite this, limited studies have been conducted on contamination and time trends on siloxanes in coastal environments. In the present study, four

Use of Industrial Wastewater for Chlorella sp. Culturing to obtain Commercially Important Compounds

open access: yesTSF Journal of Biology, 2023
In the present study, Chlorella sp. was grown in volume-graded industrial wastewater and showed increased growth in 10% and 30% of wastewater but the maximum growth was shown in 100% industrial wastewater.

Removal of Siloxanes from Biogas [PDF]

open access: yes, 2014
Economic utilisation of biogas arising from sewage sludge is hampered by the need to remove siloxanes, which damage gas engines upon combustion. This thesis applies on-line Fourier transform infrared spectroscopy to measure siloxanes in biogas ...
