Weathering microenvironments on feldspar surfaces: implications for understanding fluid-mineral reactions in soils [PDF]

open access: yes, 2008
The mechanisms by which coatings develop on weathered grain surfaces, and their potential impact on rates of fluid-mineral interaction, have been investigated by examining feldspars from a 1.1 ky old soil in the Glen Feshie chronosequence, Scottish ...

Predicting Water Cycle Characteristics from Percolation Theory and Observational Data. [PDF]

open access: yes, 2020
The fate of water and water-soluble toxic wastes in the subsurface is of high importance for many scientific and practical applications. Although solute transport is proportional to water flow rates, theoretical and experimental studies show that heavy ...

Impact of nitrogenous fertilizers on carbonate dissolution in small agricultural catchments: Implications for weathering CO2 uptake at regional and global scales [PDF]

open access: yes, 2008
The goal of this study was to highlight the occurrence of an additional proton-promoted weathering pathway of carbonate rocks in agricultural areas where N-fertilizers are extensively spread, and to estimate its consequences on riverine alkalinity and ...

Degradation of Polypropylene and Jute Fiber-Reinforced Composites Exposed to Natural and Accelerated Aging: Mechanical Properties and Wettability

open access: yesChemistry, 2021
Population growth and the way resources are being exploited are directly affecting the environment. The natural fiber market, for example, is worth billions of dollars and a huge amount of the fibers becomes waste.

Comparison Study of the Bio-degradation Property of Polylactic Acid (PLA) Green Composites Reinforced by Kenaf Fibers

open access: yesInternational Journal of Technology, 2018
Degradation of polylactic acid (PLA) was studied to investigate the best method of degradation to assist in reducing environmental pollution. Two condition of testing were conducted, which are natural weathering and landfill burial test.

Reservoir theory for studying the geochemical evolution of soils [PDF]

open access: yes, 2010
[1] Linking mineral weathering rates measured in the laboratory to those measured at the landscape scale is problematic. In laboratory studies, collections of minerals are exposed to the same weathering environment over a fixed amount of time. In natural

The Effects of Natural Weathering on Color Stability of Impregnated and Varnished Wood Materials

open access: yesAdvances in Materials Science and Engineering, 2015
The aim of this study was to investigate effects of natural weathering on color stability of Scots pine (Pinus sylvestris L.) and Oriental beech (Fagus orientalis L.) impregnated with some chemicals [tanalith-E (TN-E), adolit-KD5 (AD-KD5), and chromated ...

Performance of Spray-Dried Nanofibrillated Cellulose as Wood Varnish Reinforcement in Outdoor Environment [PDF]

open access: yesBrazilian Archives of Biology and Technology
The outdoor use of wood can be improved by coating the wood surface with varnish to reduce the effects of natural weathering. However, some varnishes quickly lose their ability to protect wood, and nanoscale additives have been used to mitigate this ...
