Phase transition and magnetocaloric properties of Mn50Ni42−xCoxSn8 (0 ≤ x ≤ 10) melt-spun ribbons
(International Union of Crystallography, 2018)"The characteristics of magnetostructural coupling play a crucial role in the magnetic field-driven behaviour of magnetofunctional alloys. The availability of magnetostructural coupling over a broad temperature range is ... -
BiFeO3 codoping with Ba, La and Ti: Magnetic and structural studies
(World Scientific , 2015)"Conventional solid state reaction method, from oxides and carbonates, was employed to prepare bismuth (Bi)-based multiferroic systems. The undoped BiFeO3 (BFO) and the codoped system with Ba, La and Ti (Bi1?xBaxFe1?yTiyO3, ... -
Ablation and optical third-order nonlinearities in Ag nanoparticles
(Dove Press Ltd, 2010)"The optical damage associated with high intensity laser excitation of silver nanoparticles (NPs) was studied. In order to investigate the mechanisms of optical nonlinearity of a nanocomposite and their relation with its ... -
Simple method to synthesize functionalized carbon nanotubes employing cobalt nitrate and acetone by using spray pyrolysis deposition technique
(Hindawi Publishing Corporation, 2012)"Recently alcohols and ketones have been employed to sensitize CNT by CVD. A study has shown the importance of the chemical nature of those carbon precursors on the characteristics of the CNT (carbon nanotubes) obtained. ... -
High-pressure synthesis of β-Ir4B5 and determination of the compressibility of various iridium borides
(American Chemical Society, 2018)"A new iridium boride, beta-Ir4B5, was synthesized under high-pressure/high-temperature conditions of 10.5 GPa and 1500 degrees C in a multianvil press with a Walker-type module. The new modification beta-Ir4B5 crystallizes ... -
Transformation temperatures and electrochemical behavior of polycrystalline Fe-Doped Ni-Mn-Ga and Co-Ni-Ga Alloys
(ESG, 2018)"The effect of Fe addition on martensitic transformation temperatures and electrochemical behavior was studied in polycrystalline Ni51.4Mn24.8-XGa23.8FeX alloys (1<x<2.2) and Co38.3Ni32.1Ga29.6 as alternative to Ni-Mn-Ga ... -
Multistability in a prion replication interconnected cell reaction network
(International Federation of Automatic Control, 2018)"Aggregation of misfolded proteins has been implicated in a number of neurodegenerative disorders including prion disease. In spite of intensive research, the detailed mechanisms of protein misfolding leading to protein ... -
Evaluation of the expression and function of the P2X7 receptor and ART1 in human regulatory T-cell subsets
(Elsevier, 2016)"Regulatory T cells that express CD39 (CD39+ Treg) exhibit specific immunomodulatory properties. Ectonucleotidase CD39 hydrolyses ATP and ADP. ATP is a ligand of the P2X7 receptor and induces the shedding of CD62L and ... -
Understanding the dynamics and contamination of an urban aquifer system using groundwater age (14C, 3H, CFCs) and chemistry
(Wiley, 2017)"The quality of the groundwater supplying drinking water to the Guadalajara metropolitan area has deteriorated due to both endogenic and exogenic processes. Previous studies of this complex neotectonic volcanic environment ... -
Landscape composition influences abundance patterns and habitat use of three ungulate species in fragmented secondary deciduous tropical forests, Mexico
(Elsevier, 2015)"Secondary forests are extensive in the tropics. Currently, these plant communities are the available habitats for wildlife and in the future they will possibly be some of the most wide-spread ecosystems world-wide. To ... -

Induced climate change impairs photosynthetic performance in Echinocactus platyacanthus, an especially protected Mexican cactus species
(Elsevier, 2014)"The responses of desert plants to climate warming have been poorly assessed, perhaps due to the overall expectation that desert vegetation will expand as a consequence of this component of climate change. However, determining ... -
Combined effect of water potential and temperature on seed germination and seedling development of cacti from a mesic Argentine ecosystem
(Elsevier, 2017)"Global climatic change will be associated with an increase of droughts and heat waves, which can affect seed germination and plant population dynamics. Cactus species from mesic ecosystems are likely to be more affected ... -
Self-association of enolase from Trichomonas vaginalis. monomers, dimers, and octamers coexist in solution
(American Chemical Society, 2018)"We used small-angle X-ray scattering to study the self-association of enolase from Trichomonas vaginalis as a function of the protein concentration and cosolute type. We observed coexisting monomers, dimers, and octamers ... -
Two P2X1 receptor transcripts able to form functional channels are present in most human monocytes
(Elsevier, 2016)"To characterize the presence and general properties of P2X1 receptors in single human monocytes we used RT-PCR, flow cytometry, and the patch-clamp and the two-electrode voltage-clamp techniques. Most human monocytes ... -
