Polymerization Efficiency of Glass-Ionomer and Resin Adhesives under Molar Bands [PDF]

, 2008
Objective: To determine the degree of cure of a light-cured resin-modified glass ionomer (RMGI) under molar bands compared with a light-cured resin and a dual-cured resin. Materials and Methods: The 3 cements used were Fuji Ortho LC, Eagle Spectrum resin,

Bright filter-free source of indistinguishable photon pairs

, 2008
We demonstrate a high-brightness source of pairs of indistinguishable photons based on a type-II phase-matched doubly-resonant optical parametric oscillator operated far below threshold.

The Ca II infrared triplet's performance as an activity indicator compared to Ca II H and K

, 2017
Aims. A large number of Calcium Infrared Triplet (IRT) spectra are expected from the GAIA- and CARMENES missions. Conversion of these spectra into known activity indicators will allow analysis of their temporal evolution to a better degree. We set out to

The impact of using a proton exchange membrane on alkaline fuel cell performance

Revista Facultad de Ingeniería Universidad de Antioquia, 2015
A hydrogen fuel cell was designed in the laboratory, operating in potentiostatic mode (1 V, 1.23 V, 1.5 V and 5 V), obtaining characteristic parameters that allow improving hydrogen production by means of electrolysis.

Anomalous polarization conversion in arrays of ultrathin ferromagnetic nanowires

, 2015
We study optical properties of arrays of ultrathin nanowires by means of the Brillouin scattering of light on magnons. We employ the Stokes/anti-Stokes scattering asymmetry to probe the circular polarization of a local electric field induced inside ...

Dimensionality of the spatio-temporal entanglement of PDC photon pairs [PDF]

, 2012
In this work the Schmidt number of the two-photon state generated by parametric-down conversion (PDC) is evaluated in the framework of a fully spatio-temporal model for PDC.
