This article will discuss the importance of Raimond Castaing's thesis on the genesis of a nondestructive and truly quantitative microanalytical method that assisted the scientific community in moving forward in the development of microanalytical instruments. I will also share with you my recollection of the decades of improvement in the electron probe microanalyzer (EPMA), that has allowed us t...

Single-crystalline V2O5 xH2O nanorings and microloops were chemically assembled via an ion-induced chemical spinning route in the designed hydrothermal system. The morphology and structure of products were investigated by means of scanning electron microscopy (SEM) and transmission electron microscopy (TEM). X-ray powder diffraction (XRD) measurement, energydispersive X-ray spectroscopy (EDS) m...

Reconstructing the history of ambient levels of metals by using tree-ring chemistry is controversial. This controversy can be resolved in part through the use of selective microanalysis of individual wood cells. Using a combination of instrumental neutron activation analysis and secondary ion mass spectrometry, we have observed systematic inhomogeneity in the abundance of toxic metals (Cr, As, ...

The concentrations of sodium, potassium, chlorine, and phosphorus and the water content in A-band and I-band of rat heart muscle cells were measured by X-ray microanalysis. Concentrations per compartment water of both cations and anions are higher in the A-band, which is less hydrated than the I-band. It is concluded that at physiological ionic strength positive and negative fixed charges are e...

A rapidly solidified A1 6 to gwt%Cr alloy formed by vapour deposition has been studied by field-ion microscopy and atom probe microanalysis (FIM/AP). The as-deposited material was found to contain brightly imaging Cr-rich particles, both spherical and rod-shaped, of about 0.5-lnm in diameter and up to 5nm long. Random area AP analysis showed the presence of Cr-enrichment on a very fine scale, w...

Nanostructuring of ultrathin HfO2 films deposited on GaAs (001) substrates by high-resolution Lloyd's mirror laser interference nanolithography is described. Pattern transfer to the HfO2 film was carried out by reactive ion beam etching using CF4 and O2 plasmas. A combination of atomic force microscopy, high-resolution scanning electron microscopy, high-resolution transmission electron microsco...

The results of ultrastructural studies and transmission electron microscope microanalysis of two Scenedesmus strains experimentally exposed to copper sulfate are presented. A fine-structural examination of the cells revealed the presence of nuclear inclusions in the form of central dense-core complexes. Cytoplasmic structures resembling the intranuclear inclusions were occasionally found in the...
