Zinc oxide grounds in 19th and 20th century oil paintings and their role in picture degradation processes

open access: yesCeROArt : Conservation, Exposition, Restauration d'Objets d'Art, 2013
When zinc oxide is the main constituent of a ground layer, its stiffness and brittle behavior could affect the whole paint system, producing damages to upper pigmented layers.

A 'manual on masculinity'? The consumption and use of mediated images of masculinity among teenage boys in Ireland [PDF]

open access: yes, 2005
Most of the research on masculinity in Ireland stresses the influences of family, work and education in the construction of gender (Ferguson, 1998; Ferguson and Synott, 1995; Ferguson and Reynolds, 2001; McKeown et al., 1998, Owens, 2000).

Infrared spectroscopic and conductometric analysis of the structural and electrochemical properties of cobalt and neodymium caprate

open access: yesNext Materials
This study investigates the structural and conductive properties of cobalt and neodymium caprates in mixed solvent systems. Using infrared spectroscopy, we found that metal-carboxylate complexes form, with metal oxygen bonds affecting the behavior of ...

Solvent-mediated extraction of fatty acids in bilayer oil paint models: a comparative analysis of solvent application methods

open access: yesHeritage Science, 2019
The impact of solvent exposure on oil paintings and the differences between solvent application methods are longstanding topics in cleaning studies. Solvent exposure is ideally kept to a minimum, because solvent swelling can lead to the extraction and ...

Health Hazard Manual For Cutting Oils, Coolants, and Metalworking Fluids [PDF]

open access: yes, 1991
[Excerpt] The metalworker can be exposed to cutting oils during application by two basic routes of entry: skin contact and inhalation. The higher risk jobs tend to be those with high cutting speeds, heavy oil flow, and continuous contact, which may ...

Geometrically Templated, Ultra‐Lightweight and High Strength Soap Films from Lyotropic Liquid Crystalline Graphene Oxide/Polymer Composites

open access: yesAdvanced Functional Materials, EarlyView.
Shellular materials form spontaneously by dip coating the primitive triply periodic minimal surface (TPMS) wireframe in an aqueous solution of lyotropic liquid crystalline graphene oxide (GO) nanosheets mixed with polymers. Regulated by surface tension, GO nanosheets align on the polymer soap film as the stress builds up during drying.

Two-step analytical procedure for the characterization and quantification of metal soaps and resinates in paint samples

open access: yesHeritage Science, 2018
Metal soaps and resinates are known to be spontaneously formed in artistic paintings, as a product of the reaction between aliphatic and terpenoid acids released by hydrolysis and oxidation of the organic media and certain cations contained in some ...

Silver Ion‐Mediated [hk1]‐Oriented Sb2Se3 Crystal Growth for Efficient Photoelectrochemical Hydrogen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
Ag+‐mediated hydrothermal crystal engineering promotes preferential [hk1]‐oriented growth of Sb2Se3 via an ultrathin MoOx interlayer, improving crystallinity and suppressing non‐radiative recombination. The optimized Ag+ treatment photocathode delivers 24.7 mA cm−2 at 0 VRHE and improved stability, revealing an ion‐modulated route to high‐performance ...
