Research paper thumbnail of Optimización superficial de alambres de ortodoncia de Ni-Ti superelástico mediante nitruración gaseosa. Parte 1: caracterización de las temperaturas de transformación y de la superelasticidad

Se han cambiado diseños y materiales de los brackets, pero no se ha trabajado con los alambres. Este estudio muestra la nitruración gaseosa como un eficaz método de mejora del deslizamiento de los alambres ortodóncicos de Ni-Ti superelástico (composiciones cercanas a la equiatómica) respecto al bracket, principal inconveniente de estas aleaciones en la aplicación ortodóncica. Se comprobó el efecto que la nitruración tiene sobre la formación de fase martensítica inducida por tensión, y por lo tanto en las propiedades superelásticas con ayuda de ensayos a tracción a 20 y 37ºC, así como con calorimetrías DSC que permiten la determinación de las cuatro temperaturas características de la transformación martensítica termoelástica: AS, MS, AF, y MF. Se observó un acusado descenso de las te...

Research paper thumbnail of Comparison of the atomic level structure of the plastic crystalline and liquid phases of CBr2Cl2: neutron diffraction and reverse Monte Carlo modelling

Journal of physics. Condensed matter : an Institute of Physics journal, Jan 13, 2013

Neutron diffraction results obtained for plastic crystalline dichlorodibromomethane (CBr2Cl2) hav... more Neutron diffraction results obtained for plastic crystalline dichlorodibromomethane (CBr2Cl2) have been modelled by means of the reverse Monte Carlo method. Comparison with its liquid phase is provided at several levels of the atomic structure (total scattering structure factors, partial radial distribution functions, orientational and dipole-dipole correlations). The results reveal that the relative orientation of neighbouring molecules largely depends on the steric effect. The small dipole moment does not have as strong an influence as the steric effect on the short-range order. Our observations fit well with earlier findings presented for the series CBr(n)Cl(4-n) (n = 0, 1, 2, 4).

Research paper thumbnail of Differential Thermal Analysis and Dielectric Studies on 2-Methyl-2-Nitro-Propane under High Pressure

Zeitschrift für Naturforschung A, 1995

TBN displays an orientationally disordered phase (ODIC), solid I, and two non-plastic phases, solids II and III. The coexistence region of the plastic phase I increases with increasing pressure, whereas the low-temperature phase II apparently vanishes at a triple point I, II, III, above 300 MPa. The static permittivity increases on freezing, characterizing the solid I as an ODIC phase. In the frame of the Kirkwood-Onsager-Fröhlich theory the g-factor is about unity, discounting specific dielectric correlations. The dielectric behaviour of TBN is similar to previously studied related compounds, such as 2-chloro-2-methyl-propane or 2-brome- 2-methyl-propane
