Combined Use of Non-Invasive and Micro-Invasive Analytical Investigations to Understand the State of Conservation and the Causes of Degradation of I Tesori del Mare (1901) by Plinio Nomellini

open access: yesMethods and Protocols, 2022
In this study, the investigation of the oil painting on canvas I Tesori del Mare made by Plinio Nomellini in 1901 is presented. The aim of the research was threefold: the examination of the state of conservation in view of the restoration treatment ...

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).

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.

Electrochemical deposition of a copper carboxylate layer on copper as potential corrosion inhibitor [PDF]

open access: yes, 2012
Carboxylic acids and sodium carboxylates are used to protect metals against aqueous and atmospheric corrosion. In this paper we describe the application of a layer of copper carboxylate on the surface of a copper electrode by means of cyclic voltammetry ...

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 ...

Stoma‐Shell Nanoarchitecture for Enhanced Plasma Confinement Catalysis in Synthesis of Ethanol from CO2

open access: yesAdvanced Functional Materials, EarlyView.
High‐energy electron impact in plasma catalysis often causes excessive dissociation of active intermediates, limiting C2+ product selectivity. To address this challenge, a bio‐inspired stoma‐shell nanoarchitecture is designed to decouple electron impact from catalytic reaction zones.
