Thermal Arrest Analysis of the Reverse Martensitic Transformation in a Ni55Fe19Ga26 Heusler Alloy Obtained by Melt-spinning
(Springer Nature, 2023)
Ni55Fe19Ga26 ribbons obtained by melt-spinning technique exhibit a martensitic transformation from L21 cubic austenite phase to 14 M martensite phase above room temperature. We have taken advantage of the existence of ...

Electrical conduction mechanisms in graphene nanoplatelet/yttria tetragonal zirconia composites
(Elsevier, 2018-08)
Yttria tetragonal zirconia polycrystalline (3YTZP) ceramic composites with 5, 10 and 20 vol% graphene nanoplatelets (GNPs) were prepared by spark plasma sintering (SPS) and their electrical conductivity as a function ...

Transfer reactions of exotic nuclei including core deformations: 11Be and 17C
(American Physical Society, 2023-08-28)
Background: Reactions with halo nuclei from deformed regions exhibit important deviations from the inert core + valence picture. Structure and reaction formalisms have recently been extended or adapted to explore the ...

Plasma assisted dry reforming of methane: Syngas and hydrocarbons formation mechanisms
(Elsevier, 2023)
Plasma reactions of CO2 + CH4 mixtures have been proposed as a suitable process for the dry reforming of methane. Without specific catalysts, most studies report the formation of CO and H2 as main reaction products and ...

Highly efficient electrical discharge machining of yttria-stabilized zirconia ceramics with graphene nanostructures as fillers
(Elsevier, 2022-06-14)
Electrical-discharge machining (EDM) of advanced ceramics allows the miniaturization of parts with complex shapes. Since electrical conductivity is required, non-conductive ceramics need a conductive second phase. This ...

A CMOL-Like Memristor-CMOS Neuromorphic Chip-Core Demonstrating Stochastic Binary STDP
(Institute of Electrical and Electronics Engineers Inc., 2022-12)
The advent of nanoscale memristors raised hopes of being able to build CMOL (CMOS/nanowire/molecular) type ultra-dense in-memory-computing circuit architectures. In CMOL, nanoscale memristors would be fabricated at the ...

Design of Broadband Aperture-Coupled Stacked Microstrip Antennas Using Second-Order Filter Theory
(IEEE, 2022-07)
In this article, the authors propose a lumped circuit methodology for the design of broadband stacked microstrip patch antennas fed through an aperture. First, an equivalent circuit (EC) is introduced for the antenna. The ...
