Journal ArticleDOI
Formation Mechanism of Fe Nanocubes by Magnetron Sputtering Inert Gas Condensation
Junlei Zhao,Ekaterina Baibuz,Jerome Vernieres,Panagiotis Grammatikopoulos,Ville Jansson,Morten Jesper Nagel,Stephan Steinhauer,Mukhles Sowwan,Mukhles Sowwan,Antti Kuronen,Kai Nordlund,Flyura Djurabekova +11 more
TL;DR: A comprehensive deposition rate-temperature diagram of Fe NP shapes is constructed and an analytical model that predicts the temporal evolution of these properties is developed that proposes a roadmap for experimentalists to engineer NPs of desired shapes for targeted applications.
Journal ArticleDOI
Gas-Phase Synthesis of Trimetallic Nanoparticles
Jean-Gabriel Mattei,Panagiotis Grammatikopoulos,Junlei Zhao,Vidyadhar Singh,Jerome Vernieres,Stephan Steinhauer,Alexander James Porkovich,Eric Danielson,Kai Nordlund,Flyura Djurabekova,Mukhles Sowwan +10 more
TL;DR: In this article, the authors present a method for engineering nano-alloys beyond bimetallic compositions, which has scarcely been within the scope of physical deposition methods due to the complex, nonequilibrium processes they entail.
Journal ArticleDOI
Gas Phase Synthesis of Multifunctional Fe-Based Nanocubes
Jerome Vernieres,Stephan Steinhauer,Junlei Zhao,Audrey Chapelle,Philippe Menini,Nicolas Dufour,Rosa E. Diaz,Kai Nordlund,Flyura Djurabekova,Panagiotis Grammatikopoulos,Mukhles Sowwan +10 more
TL;DR: In this paper, a flexible approach to produce Fe nanocubes as building blocks for high-performance NO2 gas sensor devices, and hybrid FeAu nanocules with magneto-plasmonic properties, was reported.
Journal ArticleDOI
Crystallization of silicon nanoclusters with inert gas temperature control
Junlei Zhao,Vidyadhar Singh,Panagiotis Grammatikopoulos,Cathal Cassidy,Kengo Aranishi,Mukhles Sowwan,Mukhles Sowwan,Kai Nordlund,Flyura Djurabekova +8 more
TL;DR: In this article, the fundamental process of crystallization of silicon nanoclusters was analyzed by means of molecular dynamics simulations, complemented by magnetron-sputter inert gas condensation, which was used to synthesize polycrystalline silicon nanclusters with good size control.
Journal ArticleDOI
Surface Segregation in Chromium-Doped NiCr Alloy Nanoparticles and Its Effect on Their Magnetic Behavior
Murtaza Bohra,Murtaza Bohra,Panagiotis Grammatikopoulos,Rosa E. Diaz,Vidyadhar Singh,Junlei Zhao,Jean-François Bobo,Antti Kuronen,Flyura Djurabekova,Kai Nordlund,Mukhles Sowwan,Mukhles Sowwan +11 more
TL;DR: In this article, the authors demonstrate the element-specific surface segregation in Ni-rich NiCr alloy nanoparticles and nanogranular films grown by gas-phase synthesis methods, and demonstrate the complete transformation into core-satellite structures at 700 K.
