Artificial weathering of an ordinary chondrite: Recommendations for the curation of Antarctic meteorites

Meteoritics & Planetary Science, 2022
AbstractMeteorites are prone to errestrial weathering not only after their fall on the Earth’s surface but also during storage in museum collections. To study the susceptibility of this material to weathering, weathering experiments were carried out on polished sections of the H5 chondrite Asuka 10177.

Stone Endurance: A Comparative Analysis of Natural and Artificial Weathering on Stone Longevity

Heritage, 2023
The long-term endurance of building stones must be assured since their longevity has repercussions for their economic and social value. Frequently, slabs for flooring and cladding are installed with polished finishing in outdoor environments for ...

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

Heliyon, 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

BioResources, 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 ...

Enhancing the UV/heat stability of LLDPE irrigation pipes via different stabilizer formulations

SPE Polymers, 2021
Herein different stabilizer formulations of linear low‐density polyethylene (LLDPE) against UV‐ and heat‐initiated degradation are described. The project aims at outdoor applications, such as irrigation piping and profiles, in the Middle East desert ...

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

Case 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 ...

Can Weather be Influenced by Artificial Means? [PDF]

Nature, 1871
SOME remarks on this subject made by the Rev. R. B. Belcher before the Geological Section of the British Association (reported in the Athenaeum of October 29), reopen a question of popular meteorology, which has not, perhaps, been sufficiently attended to, from an exact and scientific point of view.

Durability of Flame-Retarded, Co-Extruded Profiles Based on High-Density Polyethylene and Wheat Straw Residues

Molecules, 2021
At present, little information is available in the scientific literature related to the durability (weathering resistance) of fire-retarded wood and natural fiber-reinforced thermoplastics.
