Insight into crystal structure/optical properties relationships of newN-salicylidene anils

The Crystal and Molecular Structure and Properties of DiaquajN-salicylidene—(S)—( + ) —glutamato]copper(II) Monohydrate

The crystal and molecular structure o f the title complex was determinated by single crystal X-ray diffraction (R = 0.066 for 1059 observed reflections). The approximately square-pyram­ idal coordination o f Cu(II) results from donor atoms 0 (12), 0 (1 ), N (l) , 0 (5 ) o f one H20 mo­ lecule as well as the tridentate Schiff base dianion ligand and from the weakly bonded 0(11) donor atom of one...

Permittivity spectroscopy - an insight into materials properties.

Permittivity Spectroscopy is a branch of the Impedance Spectroscopy specially tuned for measurements and analyses of dielectrics permittivity properties. The present paper presents experimental results on permittivity properties of composite objects in which a polarizable dielectric is distributed in a fine non-polarizable matrix (solid or liquid) measured in frequency range 1 MHz down to 0.01 ...

Mitophagy: New Insight into the Cardiovascular Aging  

Theoretical insight into the antioxidant properties of melatonin and derivatives.

Density functional theory calculations on melatonin, metabolites and synthetic derivatives thereof, and a range of other biological antioxidant molecules are presented, with a view to understanding the antioxidant ability of these molecules. After testing of the necessary calculations, we show that melatonin lies close to vitamin E on a donor-acceptor map, indicating that it should be an excell...

Insight into differences in nanoindentation properties of bone.

Nanoindentation provides the ideal framework to determine mechanical properties of bone at the tissue scale without being affected by the size, shape, and porosity of the bone. However, the values of tissue level mechanical properties vary significantly between studies. Since the differences in the bone sample, hydration state, and test parameters complicate direct comparisons across the variou...
