Trace metals in the open oceans : speciation modelling [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 ...

Complexes from Complexes

open access: yesFoundations of Computational Mathematics, 2021
This paper is concerned with the derivation and properties of differential complexes arising from a variety of problems in differential equations, with applications in continuum mechanics, relativity, and other fields. We present a systematic procedure which, starting from well-understood differential complexes such as the de Rham complex, derives new ...

Development and application of an assay for uranyl complexation by fungal metabolites, including siderophores [PDF]

open access: yes, 2003
An assay to detect UO2 2+ complexation was developed based on the chrome azurol S (CAS) assay for siderophores (B. Schwyn and J. B. Neilands, Anal. Biochem.

The complexity of cutting complexes [PDF]

open access: yesDiscrete & Computational Geometry, 1989
This paper investigates the combinatorial and computational aspects of certain extremal geometric problems in two and three dimensions. Specifically, we examine the problem of intersecting a convex subdivision with a line in order to maximize the number of intersections.

Studying Complexity is Complex [PDF]

open access: yesJournal of General Internal Medicine, 2007
This supplement contains 9 articles that arose from a Department of Veterans Affairs sponsored State of the Art (SOTA) conference “Managing Complexity in Chronic Care.” It is appropriate that these articles appear in the Journal of General Internal Medicine.

Effect of Nature of Substituents on Coordination Properties of Mono- and Disubstituted Derivatives of Boron Cluster Anions [BnHn]2– (n = 10, 12) and Carboranes with exo-Polyhedral B–X Bonds (X = N, O, S, Hal)

open access: yesInorganics, 2022
This review systematizes data on the coordination ability of mono- and disubstituted derivatives of boron cluster anions and carboranes in complexation with transition metals.

The Formation of Inherently Chiral Calix[4]quinolines by Doebner–Miller Reaction of Aldehydes and Aminocalixarenes

open access: yesMolecules, 2022
The formation of inherently chiral calix[4]arenes by the intramolecular cyclization approach suffers from a limited number of suitable substrates for these reactions.

Complexation of norfloxacin with DNA in the presence of caffeine [PDF]

open access: yes, 2006
1H NMR spectroscopy (500 MHz) has been used to quantify the complexation of the antibacterial antibiotic Norfloxacin (NOR) with DNA in the presence of Caffeine (CAF). Separate studies have been made for the self-association of NOR, its hetero-association

Recovery and Utilization of Pea Albumins as Acidic Emulsion Stabilizer by Complexation with Dextran Sulfate

open access: yesFoods, 2022
In this work, pea albumins (PAs) were efficiently recovered by complexation with dextran sulfate (DS), and the emulsifying ability and stability of PA/DS complexes were studied.

Marine Exopolysaccharide Complexed With Scandium Aimed as Theranostic Agents

open access: yesMolecules, 2021
(1) Background: Exopolysaccharide (EPS) derivatives, produced by Alteromonas infernus bacterium, showed anti-metastatic properties. They may represent a new class of ligands to be combined with theranostic radionuclides, such as 47Sc/44Sc.
