Phase conversions in neutron stars: Implications for stellar stability and gravitational wave astrophysics
(Multidisciplinary Digital Publishing Institute, 2021-12)
We review the properties of hybrid stars with a quark matter core and a hadronic mantle, focusing on the role of key micro-physical properties such as the quark/hadron surface and curvature tensions and the conversion speed ...
The energetic antipodes and axes of the earth govern living beingsLas antípodas energéticas y ejes de la tierra gobiernan a los seres vivos

Frustration and anomalous behavior in the Bell-Lavis model of liquid water
(AMER PHYSICAL SOC, 2008)
We have reconsidered the Bell-Lavis model of liquid water and investigated its relation to its isotropic version, the antiferromagnetic Blume-Emery-Griffiths model on the triangular lattice. Our study was carried out by ...
One-Step Synthesis of Methoxylated Phloroglucinol Derivatives Promoted by Niobium Pentachloride: An Experimental and Theoretical Approach
(2017-06-01)
Phloroglucinol derivatives are an important class of natural compounds featuring the rhodomyrtone derivatives. In this work, the synthesis of compounds with a structure core of rhodomyrtosone I is described using a ...
Theoretical-Experimental Photophysical Investigations of the Solvent Effect on the Properties of Green- and Blue-Light-Emitting Quinoline Derivatives
(2017-09-01)
This paper describes the investigations on the solvatochromic effect and the photophysical properties of quinoline derivatives, compounds with potential applicability in optoelectronic devices. Using an experimental and ...
Discovery of an Extremely High Velocity, Massive, and Compact Molecular Outflow in Norma
(2008)
G331.5–0.1 in the Norma spiral arm is one of the most luminous and extended cores of a giant molecular cloud (GMC), containing at least six massive and dense dust condensations. Here we report the discovery, from observations ...
