Se describe la implementación interactiva y unificada de las técnicas Magnetometría Efecto Kerr (MEK) Medición Coeficiente Magnetoeléctrico (ME) bajo el entorno programación LabVIEW, a temperatura ambiente. Las dos fueron representadas por módulos los cuales contienen subrutinas que permiten registrar, filtrar procesar respuesta magnetoóptica o magnetoeléctrica una muestra estudio, directamente desde computador. Esos acoplar distintos dispositivos eléctricos, electrónicos, magnéticos ópticos...
Aerosol-assisted chemical vapor deposition (AACVD) is a technique implicates the atomization of precursor solution into fine droplets which are dragged by hot air flow throughout mobile nozzle unto heated reaction zone where occurring reactions. In this work, implementation mechanical, electrical and electronic components for AACVD in descriptive way presented. Equipment experimental methods implemented described, together to automatization criteria nozzle, temperature control heating plate...
A proportional detector for gas flow was designed, which can be applied to analyze both, bulk and thin films samples, using the Conversion Electron Mössbauer Spectroscopy technique (CEMS). The prototype is a stainless steel cylindrical chamber with extrusions input output flow, conductive strands sample holder bound micrometer, allows vary distance between copper strands. mixture of 95% He + 5% CH4, serves as signal multiplier in turn controls electron multiplication avoiding discharges that...
Se desarrollo un proceso para la calibracion de horno tubular marca Industrias Terrigeno, Modelo ESP serie 462 en rango 700 °C a 1000 °C, con el fin determinar exactitud y intervalo confianza temperatura programada equipo cuando se efectuan tratamientos termicos materiales estudiados. Utilizando analisis metrologico estandar calculo incertidumbres medidas directas, concluye que contribucion incertidumbre expandida, por tipo B debido especificaciones del es 2% maxima oC oC.
The design, construction and operation parameters of a gas flow proportional counter are presented in order to implement the integral conversion electron mössbauer spectroscopy technique (ICEMS). detector works with support multi-channel detection system source highenergy radiation 57Co. A constant mixture 5% CH4 He was used as multiplier gas, which increased signal intensity, protected sample´s surface electric shocks. An internal filter for low energy X-rays considered during design...
Abstract By mean of mechanical alloying the synthesis Bi 0.4 Sr 0.6 FeO 3–δ ceramic powders were achieved according to stoichiometric relations 2 O 3 , Fe and SrCO initial powders. Then thermal treatments in air both 800 °C as 825 at function on time was carried out processed powders, which posteriorly characterized via X-ray diffraction thermogravimetric. Finally, uniaxial compaction chosen performed adding polyvinyl alcohol (PVA) or butyral (PVB) try find a higher porosity. The milled...
