Peculiarities of the structural and optical properties of rare-earth-doped phosphate glasses for temperature sensing applications
(Elsevier, 2021)
info:eu-repo/semantics/article,
Eu, Er, Yb-Er, and Dy-doped phosphate glasses were prepared by a wet-route processing of chemical precursors followed by melt-quenching and annealing. XRD measurements highlighted the amorphous nature of the investigated ...
Optimal strain-gauge placement for mechanical load estimation in circular cross-section shafts
(Elsevier, 2021)
Artículo / Artikulua,
The customary electrical circuit configuration for estimating mechanical loads with strain gauges uses Wheatstone full- or half-bridges. For each mechanical load to be estimated, a dedicated bridge with two or four gauges
has ...
Novel bloch wave excitation platform based on few-layer photonic crystal deposited on D-shaped optical fiber
(Nature Research, 2021)
Artículo / Artikulua,
With the goal of ultimate control over the light propagation, photonic crystals currently represent the primary building blocks for novel nanophotonic devices. Bloch surface waves (BSWs) in periodic dielectric multilayer ...
Optimum power transfer in RF front end systems using adaptive impedance matching technique
(Nature Research, 2021)
Artículo / Artikulua,
Matching the antenna’s impedance to the RF-front-end of a wireless communications system is challenging as the impedance varies with its surround environment. Autonomously matching the antenna to the RF-front-end is therefore ...
Interdigital concept in photonic sensors based on an array of lossy mode resonances
(Nature Research, 2021)
Artículo / Artikulua,
Multi-parameter detection is key in the domain of sensors. Here it is demonstrated that an indium tin oxide (ITO) nanocoating can be used to generate multiple lossy mode resonances (LMRs) in the optical spectrum. To achieve ...
Experimental development and testing of low-cost scalable radiative cooling materials for building applications
(Elsevier, 2021)
Artículo / Artikulua,
Urban overheating has a serious impact on building energy consumption. Daytime radiative cooling materials are an interesting passive solution for refrigeration. However, their costs and complex manufacturing hinder their ...
Enhanced thermal performance of photovoltaic panels based on glass surface texturization
(Elsevier, 2021)
Artículo / Artikulua,
Photovoltaic module temperature is a detrimental parameter influencing the energy yield and the durability of photovoltaic systems. Among the passive strategies to reduce the operating temperature of solar cells, radiative ...

(IEEE, 2021)
Artículo / Artikulua,
This work provides an intensive and comprehensive in-depth study from an empirical and modeling approach of the environmental radiofrequency electromagnetic fields (RF-EMF) radiation exposure in public shopping malls, as ...
A metasurface-based single-layered compact AMC-backed dual-band antenna for off-body IoT devices
(IEEE, 2021)
info:eu-repo/semantics/article,
In this article, a compact printed monopole dual-band antenna using artificial magnetic conductor (AMC)-plane with improved gain and broader bandwidth, applicable for off-body internet of things (IoT) devices is presented. ...
Robust active damping strategy for DFIG wind turbines
(IEEE, 2021)
info:eu-repo/semantics/article,
Doubly fed induction generators (DFIGs) with an LCL filter are widely used for wind power generation. In these energy conversion systems, there is an interaction between the grid-side converter (GSC) and the rotor-side ...
