Enhanced pairing of quantum critical metals near d=3+1
(American Physical Society, 2015-07)
We study the dynamics of a quantum critical boson coupled to a Fermi surface in intermediate energy regimes where the Landau damping of the boson can be parametrically controlled, either via large Fermi velocity or by ...
Surface Porphyrins Metalate with Zn Ions from Solution
(American Chemical Society, 2015-12)
Controlling the metalation of surface porphyrins is a critical process in porphyrin-based devices. Indeed, surface porphyrins are known to metalate in ultrahigh vacuum from codeposited metal atoms or substrate atoms; ...
Critical concentration for the doping-induced metal–nonmetal transition in cubic and hexagonal GaN
(2002-09-01)
The critical concentration for the metal–nonmetal transition has been calculated for n-type and p-type GaN. Both cubic and hexagonal structures of GaN have been considered. Three different computational methods have been ...
TRACE METAL THERMODYNAMIC SPECIATION WITH HUMIC SUBSTANCES: THE NICA-DONNAN MODEL
(Soc Brasileira Quimica, 2017-10-01)
This work presents a critical overview of the NICA-Donnan model for trace metal thermodynamic speciation with humic substances obtained from natural organic matter in soils, natural waters and anthropogenic sources. A first ...
