Preparation of Various Nanomaterials via Controlled Gelation of a Hydrophilic Polymer Bearing Metal-Coordination Units with Metal Ions

open access: yesGels, 2022
We investigated the gelation of a hydrophilic polymer with metal-coordination units (HPMC) and metal ions (PdII or AuIII). Gelation proceeded by addition of an HPMC solution in N-methyl-2-pyrrolidone (NMP) to a metal ion aqueous solution.

Thoraco-abdominal coordination and performance during uphill running at altitude. [PDF]

open access: yesPLoS ONE, 2017
INTRODUCTION:Running races on mountain trails at moderate-high altitude with large elevation changes throughout has become increasingly popular. During exercise at altitude, ventilatory demands increase due to the combined effects of exercise and hypoxia.

Study of Ni(II) and Cu(II) complexeswith Schiff base octadented [PDF]

open access: yesمجلة جامعة الانبار للعلوم الصرفة, 2012
The reaction between 3,3-,4,4– tetraaminobiphenyl and o-hydroxy benzaldehyde in 1:4 molar ratio affords a novel tetrabasic octadentate Schiff base (Fig(1) ) . Its reaction with Ni(OAc)2 in 1:2 molar ratio. Leads to the formation of dinuclear complexes of

Negative thermal expansion induced by coordination number change in high-entropy oxides [PDF]

open access: yesAIP Advances
Coordination number changes in chemical bonds sometimes produce a gigantic volume change, as exemplified by the α–β transition in tin. We have achieved a giant negative thermal expansion (NTE) using four-to-six coordination number change in high-entropy ...

An Electrophysiological Model for Assessing Cognitive Load in Tacit Coordination Games

open access: yesSensors, 2022
Previously, it was shown that some people are better coordinators than others; however, the relative weight of intuitive (system 1) versus deliberate (system 2) modes of thinking in tacit coordination tasks is still not resolved. To address this question,

Global Geometrical Coordinates on Falbel's Cross-Ratio Variety [PDF]

open access: yesCanadian Mathematical Bulletin, 2009
AbstractFalbel has shown that four pairwise distinct points on the boundary of a complex hyperbolic 2-space are completely determined, up to conjugation in PU(2, 1), by three complex cross-ratios satisfying two real equations. We give global geometrical coordinates on the resulting variety.

Association between care coordination tasks with non-VA community care and VA PCP burnout: an analysis of a national, cross-sectional survey

open access: yesBMC Health Services Research, 2021
Background The scope of care coordination in VA primary care increased with the launch of the Veterans Choice Act, which aimed to increase access through greater use of non-VA Community Care.

Two Novel Pyrene Tetra-Sulfonate Europium Coordination Polymers: Structure Formation Mechanism Analysis and Sequential Modulation Strategy

open access: yesCrystals, 2022
For the purpose of broadening the understanding of the sulfonic acid coordination mechanism, a coordination system consisting of Eu(III) ion and 1,3,6,8-pyrene tetra-sulfonate (1,3,6,8-PTS) ligand was chosen as the typical research object.
