Elucidating the role of shape anisotropy infaceted magnetic nanoparticles using biogenicmagnetosomes as a model
(Royal Society of Chemistry, 2020-08-14)
Shape anisotropy is of primary importance to understand the magnetic behavior of nanoparticles, but a rigorous analysis in polyhedral morphologies is missing. In this work, a model based on finite element techniques has ...
Magnetotactic bacteria for cancer therapy
(American Institute of Physics, 2020-08-21)
Magnetotactic bacteria (MTB) are aquatic microorganisms that are able to biomineralize membrane-enclosed magnetic nanoparticles called magnetosomes. Inside the MTB, magnetosomes are arranged in a chain that allows MTB to ...
The Performance of the Magneto-Impedance Effect for the Detection of Superparamagnetic Particles
(MDPI, 2020-03-31)
The performance of magneto-impedance sensors to detect the presence and concentration of magnetic nanoparticles is investigated, using finite element calculations to directly solve Maxwell’s equations. In the case ...
Half-Hedgehog Spin Textures in sub-100 nm Soft Magnetic Nanodots
(Royal Society Of Chemistry, 2020-09-28)
Topologically non-trivial structures such as magnetic skyrmions are nanometric spin textures of outstanding potential for spintronic applications due to their unique features. It is well known that Neel skyrmions of definite ...
Real Time Monitoring of Calcium Oxalate Precipitation Reaction by Using Corrosion Resistant Magnetoelastic Resonance Sensors
(MDPI, 2020-05-14)
The magnetoelastic resonance is used to monitor the precipitation reaction of calcium oxalate ( CaC2O4 ) crystals in real-time, by measuring the shift of the resonance frequency caused by the mass increase on the resonator. ...
Improved Determination of Q Quality Factor and Resonance Frequency in Sensors Based on the Magnetoelastic Resonance Through the Fitting to Analytical Expressions
(MDPI, 2020-10-22)
The resonance quality factor Q
is a key parameter that describes the performance of magnetoelastic sensors. Its value can be easily quantified from the width and the peak position of the resonance curve but, when the ...
