Process optimization and properties of lead zirconate titanate (PZT) films for piezoelectric micromachined ultrasonic transducers (pMUTs) for scanning probe devices will be presented. The goal of the work was a replacement of the tetragenic and mutagenic s ...
In this work the effect of mixing on a sol-gel process is quantitatively investigated. Titanium dioxide synthesis from titanium tetra-isopropoxide is used as a test reaction. Solutions of titanium alkoxide in isopropyl alcohol and water in isopropyl alcoho ...
The goal of the present study was to assess the possibility to change the composition of a calcium phosphate scaffold from a high-temperature phase to a phase only stable at or close to room temperature without macrostructural changes. For that purpose, ma ...
Intergranular penetration of liquid bismuth has been analysed in two pure metals, Cu at 500°C and Ni at 700°C, used either as polycrystals or as oriented bicrystals. At the liquid/solid interface, large grooves have developed in Cu-Bi, while micrometer-thi ...
Sample preparation and scanning electron microscopy imaging methods were developed to characterize solid-oxide fuel cell anodes made out of a nickel- yttria-stabilized zirconia porous cermet. The sample preparation uses only tripod polishing and does not r ...
In a recent contribution, we have reported that dendrites in the aluminum-zinc binary system can change their growth direction continuously from {100} to {110} as the concentration of zinc CZn increases from 5 to 90 wt pct.[1] This was interpreted as an in ...
Syntheses of ZSM-5 coatings on stainless steel plates were carried out via the substrate heating method. The reaction mixture was kept at temperatures below 100 °C, while the metal plates were heated to temperatures above 100 °C. It was demonstrated that c ...
Be has a tendency to form particularly brittle intermetallics with Cu and a lot of other elements. Insertion of interlayers may be a solution to increase bond quality. Ion Beam Analysis (IBA) methods have been considered together with scanning electron mic ...
Degradation observed on long term stack tests may be explained in part by microstructural changes of the electrodes. Particularly at the anode side, the coarsening of nickel particles will affect its performances. Increasing the metal particle size will fi ...
Scanning Electron Microscopy Image Analysis (SEM-IA) was used to quantify the degree of alkali silica reaction in affected microbars, mortar and concrete prisms. It was found that the degree of reaction gave a unique correlation with the macroscopic expans ...
