TL;DR: The drying and oxidative degradation of linseed oil have been investigated through exposition of samples in form of thin films to indoor laboratory conditions, or treated at a constant temperature of 80°C, or with irradiation at wavelengths >295 mm as discussed by the authors.

TL;DR: In this article, the authors used Fourier transform infrared spectroscopy to investigate the oxidative polymerisation of linseed oil in presence of cobalt 2-ethylhexanoate drier.

TL;DR: In this paper, the influence of pigments on the long term changes in the oil binding medium was analysed using Fourier transform infrared spectroscopy (FTIR) and it was shown that pigments can significantly alter the infrared spectra of drying oil, and should therefore be identified to ensure correct assessment of the infrared spectrum in the drying paint.
Abstract: Describes the changes in the infrared spectra of oil paint as a result of ageing. The focus is on the influence of pigments on the long term changes in the oil binding medium. Several naturally aged paints made with different pigments were analysed using Fourier-transform infrared spectroscopy (FTIR). One of the most pronounced effects observed in the infrared spectra of ageing paint is the shifting and broadening of the carbonyl band due to the formation of carboxylic acids. Another effect of pigments on the oil binding medium is the catalysis of the hydrolysis of triglycerides, as indicated by the increasing intensity of the ester absorption. Finally, the nature of the pigments included has a profound effect on the CH strength absorptions. From these results it is clear that pigments can significantly alter the infrared spectra of drying oil, and should therefore be identified to ensure correct assessment of the infrared spectra in the drying paint.

11 Jun 2002TL;DR: In this article, a solid electrolytic capacitor with an anode that contains a valve-action metal (e.g., tantalum, niobium, and the like) and a dielectric film overlying the anode is provided.
Abstract: A solid electrolytic capacitor having an anode that contains a valve-action metal (e.g., tantalum, niobium, and the like) and a dielectric film overlying the anode is provided. The capacitor also include a protective coating overlying the dielectric film, wherein the protective coating contains a relatively insulative, resinous material. For example, in one embodiment, the resinous material can be a drying oil, such as olive oil, linseed oil, tung oil, castor oil, soybean oil, shellac, and derivatives thereof. The capacitor also includes a conductive polymer coating overlying the protective coating. As a result of the present invention, it has been discovered that a capacitor can be formed that can have a relatively low leakage current, dissipation factor, and equivalents series resistance.

TL;DR: In this paper, a reliable analytical procedure has been developed for the characterisation of drying oils and proteinaceous binders in samples of painted artworks, which is based on microwave assisted acid hydrolysis followed by the extraction of the lipid component with diethyl ether.
