Synthesis and deposition of silver nanoparticles on porous titanium substrates for biomedical applications
(Elsevier, 2021-01)
Ti implants are highly biocompatible and allow orderly bone growth but, unfortunately, in the first five years after implantation, 5–10% of them fail due to poor osseointegration and to the presence of bacterial infections ...

Combined kinetic and Bean–Rodbell approach for describing field-induced transitions in LaFe11.6Si1.4 alloys
(Institute of Physics Publishing, 2021)
We propose a combination of the Kolmogorov–Johnson–Mehl–Avrami nucleation and growth theory and the Bean–Rodbell model to describe the field-induced transition in LaFe11.6Si1.4 alloys. The approach is applied to a set of ...

Ultra-low Hysteresis in Giant Magnetocaloric Mn1-xVxFe0.95(P,Si,B) Compounds
(Elsevier, 2023)
Large thermal hysteresis in the (Mn,Fe)2(P,Si) system hinders an efficient heat exchange and thus limits the magnetocaloric applications. Substitution of manganese by vanadium in the Mn1-x1Vx1Fe0.95P0.593Si0.33B0.077 and ...
