EPFL2023Paper of RILEM TC 282-CCL: mineralogical characterization methods for clay resources intended for use as supplementary cementitious material
Franco Alberto Zunino Sommariva, Alastair Thomas Matthew Marsh, Ruben Anton Snellings, Adrian Alujas Diaz
To respond to the rapid introduction and development of calcined clays as supplementary cementitious material (SCM), the toolbox of characterization methods for cementitious materials requires extension to raw clay characterization. Borrowing concepts and ...
SPRINGER2022Effect of chromium content on microstructural evolution of CoNiAlW superalloy
Effects of chromium (Cr) content on types and morphologies of various phases of a newly developed Co-Ni-Al-W superalloy (Co-30Ni-6W-9Al-3Ti-1Ta) have been investigated in this study. Microstructural examinations were carried out by field-emission scanning ...
SPRINGER HEIDELBERG2022Systematic investigations of uranium carbide composites oxidation from micro- to nano-scale: Application to waste disposal
The production of radioisotope beams at the ISOLDE (Isotope Separator OnLine DEvice) facility at CERN is achieved by irradiating target materials (e.g. uranium carbides and metal foils) with protons. The materials are usually operated at temperatures above ...
