EBSD study of variant reorientation, texture, and twin formation in a martensitic NiTi alloy deformed in compression
Roland Logé, Cyril Cayron, Mathijs Pieter van der Meer, Junfeng Xiao
Martensitic crystallography plays a vital role in the texture evolution and mechanical properties in Nickel-Titanium (NiTi) shape memory alloys when subjected to deformation. However, their microstructural changes during deformation are not well known and ...
Oxford2023Monolithic InSb nanostructure photodetectors on Si using rapid melt growth
Anna Fontcuberta i Morral, Nicholas Paul Morgan, Heera Menon
Monolithic integration of InSb on Si could be a key enabler for future electronic and optoelectronic applications. In this work, we report the fabrication of InSb metal-semiconductor-metal photodetectors directly on Si using a CMOS-compatible process known ...
ROYAL SOC CHEMISTRY2023Anomalous Hall effect and magnetic structure of the topological semimetal (Mn0.78Fe0.22)3Ge
Me3+8Ge, being a Weyl semimetal, shows a large anomalous Hall effect (AHE), which decreases slowly with an increase in 8 from 0.1 to 0.4. However, AHE in this compound remains significantly large in the whole range of 8 because of the robust nature of the ...
AMER PHYSICAL SOC2023A model of non-Maxwellian electron distribution function for the analysis of ECE data in JET discharges
Javier García Hernández, Mikhail Maslov, Samuele Mazzi
Recent experiments performed in JET at high level of plasma heating, in preparation of, and during the DT campaign have shown significant discrepancies between electron temperature measurements by Thomson Scattering (TS) and Electron Cyclotron Emission (EC ...
E D P SCIENCES2023Stable Ta2O5 nanotubes decorated by PbS by the SILAR method for photocatalytic dye degradation
Tantalum oxide Ta2O5 nanotubes (NTs) were prepared by electrochemical anodization and were decorated with lead sulfide nanoparticles PbS (NPs) by Successive Ionic Layer Adsorption and Reaction commonly known as the SILAR method. The PbS NPs/Ta2O5 NTs were ...
2023Effect of Mo addition on the mechanical and tribological properties of magnetron sputtered TiN films
Ternary-based titanium nitride (TiN) thin films have drawn attention toward rational applications due to their wear resistance, high hardness, and corrosion resistance. The influence of Mo content on the structural, tribo-logical, and mechanical properties ...
ELSEVIER SCIENCE SA2023Direct Observation of the Phase Transition in C60 Fullerene
In the third study, the order-disorder phase transition of single-crystal C60 is studied using time-resolved electron microscopy. Solid C60 undergoes a first-order phase transition upon heating to 260 K. This is a structural transition from the low-tempera ...
EPFL Infoscience2023Plasmonic effects in the neutralization of slow ions at a metallic surface
Secondary electron emission is an important process that plays a significant role in several plasma-related applications. As measuring the secondary electron yield experimentally is very challenging, quantitative modelling of this process to obtain reliabl ...
WILEY-V C H VERLAG GMBH2023Simple shear extrusion versus equal channel angular pressing: A comparative study on the microstructure and mechanical properties of an Mg alloy
Roland Logé, Cyril Cayron, Aryan Rezaei Rad
Two severe plastic deformation (SPD) techniques of simple shear extrusion (SSE) and equal channel angular pressing (ECAP) were employed to process an extruded Mg -6Gd -3Y -1.5Ag (wt%) alloy at 553 K for 1, 2, 4 and 6 passes. The microstructural evolutions ...
KEAI PUBLISHING LTD2023Microscopic Digital Image Correlation Analysis of Strain Distributions in Stainless Steel 316L Induced by Multiaxial Cyclic Loading
Fatigue damage in materials results in localized strain at the microstructural level. In many engineering components of the cooling circuits of nuclear power plants, where austenitic steels are used, the material experiences multiaxial cyclic loading, eith ...
