Innovative Processing of Compacted Waste Aluminum Alloy Powders via Controlled Remelting and Solidification

Advanced Engineering Materials, EarlyView.
This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Electron pairing and chemical bonds. On the accuracy of the electron pair model of chemical bond

Computational and Theoretical Chemistry, 1997
Abstract The accuracy of the Lewis electron pair model of the chemical bond is reinvestigated. It is shown that, contrary to previous pessimistic findings, the accuracy of this model is high enough to represent a good basis for the understanding and interpretation of molecular structure, not only for molecules well described by a classical structural

The neurobiology of pair bonding

Nature Neuroscience, 2004
A neurobiological model for pair-bond formation has emerged from studies in monogamous rodents. The neuropeptides oxytocin and vasopressin contribute to the processing of social cues necessary for individual recognition. Mesolimbic dopamine is involved in reinforcement and reward learning. Concurrent activation of neuropeptide and dopamine receptors in

Bond-bond pair calculations of rotational barriers

Chemical Physics Letters, 1985
Ab initio STO-3G calculations of rotation barriers in six single-rotor molecules have shown the inadequacy of the Mulliken approximation in the Surjan formula which expresses barriers as a sum of bond-bond pair interactions. Following our early work, expansion to order S2 followed by pair delocalization is suggested as a possible alternative to semi ...

Anatomy and neurochemistry of the pair bond

Journal of Comparative Neurology, 2005
AbstractStudies in monogamous rodents have begun to elucidate the neural circuitry underlying the formation and maintenance of selective pair bonds between mates. This research suggests that at least three distinct, yet interconnected, neural pathways interact in the establishment of the pair bond.
