Influence of the processing route on the carbon nanotubes dispersion and creep resistance of 3YTZP/SWCNTs nanocomposites
(The American Ceramic Society, 2014)3YTZP matrix composites containing 2.5 vol% of single-walled carbon nanotubes (SWCNT) were fabricated by Spark Plasma Sintering (SPS) at 1250°C, following different processing routines with the aim of optimizing the SWCNTs ... -
Additive-free superhard B4C with ultrafine-grained dense microstructures
(The American Ceramic Society, 2014)A unique combination of high-energy ball-milling, annealing, and spark-plasma sintering has been used to process superhard B4C ceramics with ultrafine-grained, dense microstructures from commercially available powders, ... -
High-temperature deformation mechanisms in monolithic 3YTZP and 3YTZP containing single-walled carbon nanotubes
(Wiley, 2015)Monolithic 3YTZP and 3YTZP containing 2.5 vol% of single-walled carbon nanotubes (SWCNT) were fabricated by Spark Plasma Sintering (SPS) at 1250°C. Microstructural characterization of the as-fabricated 3YTZP/SWCNTs composite ... -
Understanding the plasma and power characteristics of a self-generated steam bubble discharge
(IOP Publishing, 2015)Plasma formation in a self-generated steam bubble is studied using a coaxial discharge tube with an axial powered electrode (nominal peak operating voltage 2000 V) and an external ground lead without any gas flow. The ... -
Measuring the electron density in plasmas from the difference of Lorentzian part of the widths of two Balmer series hydrogen lines
(Elsevier, 2015)We present an alternative optical emission spectroscopy method to measure the plasma electron density from the difference of widths of two Balmer series hydrogen lines (Hα and Hβ), especially convenient for non-thermal ... -
An investigation of an underwater steam plasma discharge as alternative to air plasmas for water purification
(IOP Publishing, 2015)An underwater steam plasma discharge, in which water itself is the ionizing media, is investigated as a means to introduce advanced oxidation species into contaminated water for the purpose of water purification. The steam ... -
Real-Time Monitoring System for a Utility-Scale Photovoltaic Power Plant
(MDPI, 2016)There is, at present, considerable interest in the storage and dispatchability of photovoltaic (PV) energy, together with the need to manage power flows in real-time. This paper presents a new system, PV-on time, which ... -
Assessment of the Potential of UAV Video Image Analysis for Planning Irrigation Needs of Golf Courses
(MDPI, 2016)Golf courses can be considered as precision agriculture, as being a playing surface, their appearance is of vital importance. Areas with good weather tend to have low rainfall. Therefore, the water management of golf courses ... -
Dielectric Spectroscopy in Biomaterials: Agrophysics
(MDPI, 2016)Being dependent on temperature and frequency, dielectric properties are related to various types of food. Predicting multiple physical characteristics of agri-food products has been the main objective of non-destructive ... -
Solar Resource for Urban Communities in the Baja California Peninsula, Mexico
(MDPI, 2016)Several studies have determined that Mexico has great renewable energy potential, and one of its most abundant resources is solar energy, a source that could be exploited to provide development opportunities to its ... -

Comparative study on high temperature mechanical behavior in 3YTZP containing SWCNTs or MWCNTs
(Elsevier, 2016)Effects on mechanical properties of the presence of either single-walled carbon nanotubes (SWCNTs) or multi-walled carbon nanotubes (MWCNTs) in a 3YTZP matrix have been investigated in this work. Thus, monolithic 3YTZP and ... -
Clinical and Biological Principles of Cold Atmospheric Plasma Application in Skin Cancer
(Springer, 2016)Plasma-based electrosurgical devices have long been employed for tissue coagulation, cutting, desiccation, and cauterizing. Despite their clinical benefits, these technologies involve tissue heating and their effects are ... -
High temperature internal friction in a Ti–46Al–1Mo–0.2Si intermetallic, comparison with creep behaviour
(Elsevier, 2016)Advanced γ-TiAl based intermetallics Mo-bearing have been developed to obtain the fine-grained microstructure required for superplastic deformation to be used during further processing. In the present work we have studied ... -
