Introductory university physics students ’ understanding of some key characteristics of classical theory of the electromagnetic field
(American Physical Society, 2018-11-12)
In this work, we explore how undergraduate students use classical field theory when describing physical phenomena in the context of introductory electromagnetism. We have extracted five key characteristics of the electric ...
Properties of Metal–Organic Coordination Networks Based on 3d Transition Metal Atoms
(MDPI, 2018-04)
The magnetic anisotropy and exchange coupling between spins localized at the positions of 3d transition metal atoms forming two-dimensional metal-organic coordination networks (MOCNs) grown on a Au(111) metal surface are ...
Transparent Glass-Ceramics Produced by Sol-Gel: A Suitable Alternative for Photonic Materials
(MDPI, 2018-01-30)
Transparent glass-ceramics have shown interesting optical properties for several photonic applications. In particular, compositions based on oxide glass matrices with fluoride crystals embedded inside, known as oxyfluoride ...
A Decade of GRB Follow-Up by BOOTES in Spain (2003-2013)
(Hindawi, 2016)
This article covers ten years of GRB follow-ups by the Spanish BOOTES stations: 71 follow-ups providing 23 detections. Follow-ups by BOOTES-1B from 2005 to 2008 were given in a previous article and are here reviewed and ...
Reactivity of Bioinspired Magnesium-Organic Networks under CO2 and O-2 Exposure
(American Chemical Society, 2019-06-30)
Photosynthesis is the model system for energy conversion. It uses CO2 as a starting reactant to convert solar energy into chemical energy, i.e., organic molecules or biomass. The first and rate-determining step of this ...
Addressing students' difficulties with Faraday's law: A guided problem solving approach
(Amer Physical, 2014-06-30)
In traditional teaching, the fundamental concepts of electromagnetic induction are usually quickly analyzed, spending most of the time solving problems in a more or less rote manner. However, physics education research has ...
Influence of Upconversion Processes in the Optically-Induced Inhomogeneous Thermal Behavior of Erbium-Doped Lanthanum Oxysulfide Powders
(MDPI, 2016-05-11)
The efficient infrared-to-visible upconversion emission present in Er-doped lanthanum oxysulfide crystal powders is used as a fine thermal sensor to determine the influence of upconversion processes on the laser-induced ...
Metallic Glass/PVDF Magnetoelectric Laminates for Resonant Sensors and Actuators: A Review
(MDPI, 2017-05-31)
Among magnetoelectric (ME) heterostructures, ME laminates of the type Metglas-like/PVDF (magnetostrictive+piezoelectric constituents) have shown the highest induced ME voltages, usually detected at the magnetoelastic ...
Sensor Applications of Soft Magnetic Materials Based on Magneto-Impedance, Magneto-Elastic Resonance and Magneto-Electricity
(MDPI, 2014-04-25)
The outstanding properties of selected soft magnetic materials make them successful candidates for building high performance sensors. In this paper we present our recent work regarding different sensing technologies based ...
Size Dependence of the Magnetoelastic Properties of Metallic Glasses for Actuation Applications
(MDPI, 2019-10-04)
We present an exhaustive study of the magnetoelastic properties of 24 strips with different rectangular dimensions, cut from a long ribbon of Metglas((R)) 2826MB3. The strips have a length-to-width ratio R = L/w ranging ...
