Natural and simulated aging of historical glasses [PDF]

open access: yes, 2017
We thoroughly studied coloured glass tesserae of historical glass windows of the Santi Giovanni e Paolo Church in Venice by means of ESEM and XPS techniques in order to evaluate the weathering mechanisms of the glass surfaces.

Effect of Corexit 9500A on Mississippi Canyon crude oil weathering patterns using artificial and natural seawater

open access: yesHeliyon, 2017
During the 2010 Deepwater Horizon oil well blowout in the Northern Gulf of Mexico (GoM), the application of 6.97 million litres of chemical dispersants was used at the well-head and on the sea surface to promote oil degradation and weathering of the ...

Assessment of Color and Contact Angle Change of Weathered Wood in Relation to Wood Species and Different Coating Types

open access: yesBioResources, 2023
Color change was compared through artificial and outdoor weathering tests according to wood species and stain type. In the artificial weathering tests, the color change DE was the highest for the initial 200 hour, and teak solvent-based stain was the ...

Evaluating post-fire mechanical performance of S355J2W weathering steel with different artificial cooling approaches

open access: yesCase Studies in Construction Materials, 2023
Compared with carbon steel, traces of Ni, Cr, Ti, and other corrosion-resistant alloying elements were added to the matrix of bridge weathering steel, which resulted in the steel surface forming a strong adhesion and dense patina that hindered the ...

Possible role of organic matter in radiocaesium adsorption in soils [PDF]

open access: yes, 2002
The aim of this review is to examine the hypothesis that organic matter decreases the adsorption of radiocaesium on clay minerals. The factors that determine radiocaesium mobility and bioavailability in soil are briefly outlined to show why a ...
