The Cumulative Amount of Exuded Citrate Controls Its Efficiency to Mobilize Soil Phosphorus

open access: yesFrontiers in Forests and Global Change, 2020
Root exudation of citrate is discussed as mechanism to mobilize P from the soils' solid phase. Microbial processes can mitigate the mobilization efficiency of citrate.

ZnII and CuII-Based Coordination Polymers and Metal Organic Frameworks by the of Use of 2-Pyridyl Oximes and 1,3,5-Benzenetricarboxylic Acid

open access: yesMolecules, 2021
The simultaneous use of 2-pyridyl oximes (pyridine-2 amidoxime, H2pyaox; 2-methyl pyridyl ketoxime, Hmpko) and 1,3,5-benzenetricarboxylic acid (H3btc) provided access to five new compounds, namely [Zn(H2btc)2(H2pyaox)2]•2H2O (1•2H2O), [Zn(Hbtc)(H2pyaox)2]

Beyond Sugar and Ethanol Production: Value Generation Opportunities Through Sugarcane Residues

open access: yesFrontiers in Energy Research, 2020
Sugarcane is the most produced agricultural commodity in tropical and subtropical regions, where it is primarily used for the production of sugar and ethanol. The latter is mostly used to produce alcoholic beverages as well as low carbon biofuel. Despite

Effects of Phosphorus on Different Genotypes of Wheat and Canola Differing in P-Efficiency in Acidic Soils of Western Australia

open access: yesIndonesian Journal of Agricultural Research, 2021
We hypothesized that phosphorus addition would result in plant morphological changes and changes in rhizosphere carboxylates among wheat and canola cultivars in different acidic soils.

In situ surface film evolution during Mg aqueous corrosion in presence of selected carboxylates

open access: yesCorrosion Science, 2020
Mechanisms of inhibition of Mg aqueous corrosion in presence of chloride by sodium salicylate (Sal), 2,5-pyridinedicarboxylate (PDC) and fumarate (Fum) were studied by in situ Raman spectroscopy, ATR-FTIR, GD-OES and hydrogen collection. In situ detected

Rerefinement of poly[diaquabis(μ3-2-methylpropanoato-κ4O:O,O′:O′)bis(μ3-2-methylpropanoato-κ3O:O:O)(μ2-2-methylpropanoato-κ3O:O,O′)(2-methylpropanoato-κ2O,O′)trilead(II)]

open access: yesIUCrData, 2020
The crystal structure of the title complex, [Pb3(C4H7O2)6(H2O)2]n, was redetermined on basis of modern CCD-based single-crystal X-ray data at 120 K. The current study basically confirms the previous report [Fallon et al. (1997). Polyhedron, 16, 19–23] at
