Competition from Cu(II), Zn(II) and Cd(II) in Pb(II) binding to Suwannee River Fulvic Acid [PDF]

open access: yes, 2008
This is a study of trace metal competition in the complexation of Pb(II) by well-characterized humic substances, namely Suwannee River Fulvic Acid (SRFA) in model solutions.

Complexation with Polysaccharides Enhances the Stability of Isolated Anthocyanins

open access: yesFoods, 2023
Isolated anthocyanins have limited colonic bioavailability due to their instability as free forms. Thus, many methods have been fabricated to increase the stability of anthocyanins.

The Complexity of Complex Patients [PDF]

open access: yesJournal of General Internal Medicine, 2015
A s the population of the United States ages, and more and more people live with multiple chronic conditions, the issue of complex patients is receiving increasing attention. Physicians have recognized that disease-centric approaches to clinical management have serious limitations for patients with multiple co-occurring medical conditions.

Trace metals in the open oceans: speciation modelling based on humic type ligands [PDF]

open access: yes, 2011
The speciation of trace metals in the oceans is typically explained by invoking the concept of metal binding to specific organic ligands, but a lack of detailed knowledge about the ligands has impeded the formulation of comprehensive models to predict ...

Antagonistic Role of Aqueous Complexation in the Solvent Extraction and Separation of Rare Earth Ions [PDF]

open access: yes, 2021
During solvent extraction of rare earth ions, an aqueous electrolyte solution is placed in contact with an immiscible organic solution of extractants to enable extractant-facilitated transport of ions into the organic solvent.

Proton and cadmium adsorption by the archaeon Thermococcus zilligii: Generalising the contrast between thermophiles and mesophiles as sorbents [PDF]

open access: yes, 2010
Adsorption by microorganisms can play a significant role in the fate and transport of metals in natural systems. Surface complexation models (SCMs) have been applied extensively to describe metal adsorption by mesophilic bacteria, and several recent ...

Synthesis of (±)-trans-2,5-Diisopropylborolane

open access: yesMolecules, 2001
The cyclic hydroboration of 2,7-dimethyl-2,6-octadiene (6) was studied. It was found that the stereochemical outcome of the reaction was dependent upon the solvent, temperature, time and the nature of the borane reagent.
