Additive manufacturing of magnetocaloric (La,Ce)(Fe,Mn,Si)13–H particles via polymer-based composite filaments
(Elsevier, 2022-11)
Additive manufacturing could be an excellent way of shaping magnetocaloric heat exchangers in magnetic refrigerators. However, the metal additive manufacturing techniques present the serious limitation that the melting of ...

Real-Time Inter-Frame Histogram Builder for SPAD Image Sensors
(Institute of Electrical and Electronics Engineers, 2018)
CMOS image sensors based on single-photon avalanche-diodes (SPAD) are suitable for 2D and 3D vision. Limited by uncorrelated noise and/or low illumination conditions, image capturing becomes nearly impossible in a single-shot ...

Active control of Alfvén eigenmodes in magnetically confined toroidal plasmas
(IOP Publishing, 2019-05)
Alfvén waves are electromagnetic perturbations inherent to magnetized plasmas that can be driven unstable by a free energy associated with gradients in the energetic particles’ distribution function. The energetic particles ...

Efficient Spectral Domain MoM for the Design of Circularly Polarized Reflectarray Antennas Made of Split Rings
(IEEE, 2019-03)
The method of moments (MoM) in the spectral domain is used for the analysis of the scattering of a plane wave by a multilayered periodic structure containing conducting concentric split rings in the unit cell. Basis functions ...

Puzzle of Complete Fusion Suppression in Weakly Bound Nuclei: A Trojan Horse Effect?
(American Physical Society, 2019-02-01)
Experimental studies of nuclear collisions involving light weakly bound nuclei show a systematic suppression of the complete fusion cross section by ∼30% with respect to the expectation for tightly bound nuclei, at energies ...

Wall Repulsion of Charged Colloidal Particles during Electrophoresis in Microfluidic Channels
(American Physical Society, 2022)
Electrophoresis describes the motion of charged particles suspended in electrolytes when subjected to an external electric field. Previous experiments have shown that particles undergoing electrophoresis are repelled from ...

Taming the Time Evolution in Overdamped Systems: Shortcuts Elaborated from Fast-Forward and Time-Reversed Protocols
(American Physical Society, 2021)
Using a reverse-engineering approach on the time-distorted solution in a reference potential, we work out the external driving potential to be applied to a Brownian system in order to slow or accelerate the dynamics, or ...

A quantitative criterion for determining the order of magnetic phase transitions using the magnetocaloric effect
(Nature Publishing Group, 2018)
The ideal magnetocaloric material would lay at the borderline of a first-order and a second-order phase transition. Hence, it is crucial to unambiguously determine the order of phase transitions for both applied magnetocaloric ...

Mechanical properties of ceramics reinforced with allotropic forms of carbon
(Elsevier, 2022)
For decades, enormous investigation effort has been devoted to the fabrication of new ceramic matrix composites with enhanced mechanical properties. One of the most explored strategies is the addition of carbon allotropic ...

One-Photon Solutions to the Multiqubit Multimode Quantum Rabi Model for Fast W -State Generation
(American Physical Society, 2021)
General solutions to the quantum Rabi model involve subspaces with an unbounded number of photons. However, for the multiqubit multimode case, we find special solutions with at most one photon for an arbitrary number of ...
