Effects of oleothermal treatment and polydimethylsiloxane (PDMS) coating on natural weathering of beech and fir woods

Maderas: Ciencia y Tecnología, 2015
Effects of natural weathering on oleothermally treated wood and coated with an organic silicone compound were studied. Slats of beech and fir woods were cut in sizes of 20×10×1 cm. The slats were treated by soybean oil at 230˚C for 1 h. Then, the half of

Cations extraction of sandy-clay soils from cavado valley, portugal, using sodium salts solutions

Scientia Agricola, 2002
Cases of contamination by metals in the water wells of the Cavado Valley in north-west Portugal can be attributed to the heavy leaching of clay soils due to an excess of nitrogen resulting from the intensive use of fertilisers in agricultural areas. This

Infrared and Raman spectroscopy of automotive paints for forensic identification of natural weathering

, 2018
Natural weathering of automotive paint modifies the original chemical composition of this multi-layered material. As a result, the reliability of spectral forensic analysis decreases depending on the degradation level of the sample.

The dissolution of olivine added to soil at 32°C: the fate of weathering products and its implications for enhanced weathering at different temperatures

Frontiers in Climate
The amendment of agricultural soils by crushed silicate minerals has been proposed to enhance weathering rates and facilitate carbon dioxide (CO2) removal from the atmosphere. Laboratory dissolution experiments typically provide weathering rates that are
