In the present work, CeO2 nanopowder was synthesized via a reverse precipitation method using CeCl3 center dot 7H(2)O, NH4OH and sodium dodecyl sulfate as raw materials. The effect of thermal treatment on the crystal growth, surface area and chemical bonds ...
The present study investigated the role of alloy microstructure and surface roughness on wear and friction behavior of leaded and unleaded tin bronzes. Ball-on-disk experiments were carried out under dry conditions with steel balls sliding against bronze d ...
Given two samples of continuous zero-mean iid Gaussian processes on [0,1], we consider the problem of testing whether they share the same covariance structure. Our study is motivated by the problem of determining whether the mechanical properties of short ...
Although the analogies between the electron energy loss spectra and X-ray absorption spectra were recognized long ago, the possibility to observe the magnetic circular dichroism in the electron microscope was demonstrated only recently. This technique comb ...
A novel formulation for thick-film graphite sacrificial pastes is studied in this paper. It is composed of coarse graphite powder (grain size: 25 μm), dispersed in a vehicle consisting of polyvinyl alcohol (PVA) dissolved in a propylene glycol (PG)–glycero ...
In the quest of the structural materials for the future fusion reactor, it has been shown that ferritic/martensitic (F/M) steels are very promising candidates, with a good radiation resistance in terms of damage accumulation in the microstructure relative ...
Correlating in vivo imaging of neurons and their synaptic connections with electron microscopy combines dynamic and ultrastructural information. Here we describe a semi-automated technique whereby volumes of brain tissue containing axons and dendrites, pre ...
We study in this thesis the structural origin of defect insensitive light emission in indium containing group-III nitride ternary alloys grown on sapphire, which are the active materials for the commercially available high brightness blue diodes. These str ...
The design, modeling, fabrication and characterization of triplate differential capacitive sensors employed in novel on-chip tensile and compression material testing systems are reported, where the capacitive sensors are integrated to measure the load on t ...
