Thermal Arrest Analysis of the Reverse Martensitic Transformation in a Ni55Fe19Ga26 Heusler Alloy Obtained by Melt-spinning
(Springer Nature, 2023)
Ni55Fe19Ga26 ribbons obtained by melt-spinning technique exhibit a martensitic transformation from L21 cubic austenite phase to 14 M martensite phase above room temperature. We have taken advantage of the existence 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 ...

The Possible Detriment of Oxygen in Creep of Alumina and Zirconia Ceramic Composites Reinforced with Graphene
(MDPI, 2021)
This paper aims to give an answer to the following question: is the oxidation of graphene a critical issue for high-temperature plasticity in graphene-reinforced ceramics? To give a convincing reply, we will focus on two ...

Vault changes after cyclopentolate instillation in eyes with posterior chamber phakic intraocular lens
(Nature Research, 2020)
Posterior chamber phakic intraocular lens (pIOL) implantation is a common option for correcting moderate-to-high ocular refractive defects. Because this pIOL is implanted on ciliary sulcus, the distance between the back ...

Highly efficient electrical discharge machining of yttria-stabilized zirconia ceramics with graphene nanostructures as fillers
(Elsevier, 2022-06-14)
Electrical-discharge machining (EDM) of advanced ceramics allows the miniaturization of parts with complex shapes. Since electrical conductivity is required, non-conductive ceramics need a conductive second phase. This ...
