Web1 sep. 2007 · Soluble tungsten concentrations as low as 10∼ −5 mg/L cause a decrease in biomass production by 8% and are possibly related to production of stress proteins. Plants and worms take up tungsten ions from soil in significant amounts while an enrichment of tungsten in the plant rhizosphere is observed. Web14 mrt. 2024 · Amorphous tungsten oxides typically show low near infrared (NIR) light selectivity owing to the overlapped modulation of visible and NIR light originating from ion insertion induced polaronic adsorption, and poor cycling stability due to the ion trapping effects during the repeated ion insertion/extraction.
