Transmission electron microscopy (TEM) is revisited in order to define methods for the identification of nanometric defects. Nanometric crystal defects play an important role as they influence, generally in a detrimental way, physical properties. For insta ...
Investigation of the microstructure, properties and biocompatibility of the Ti-6Al-4V alloy nitrided under glow discharge was performed. The microstructural analyses were carried out using light microscopy, X-ray diffraction, analytical scanning and transm ...
Ternary Pt-based nanoparticles (nominal composition Pt80Ru10Sn10 ) were synthesized via the microemulsion route and deposited onto boron-doped diamond (BDD) electrode. The particle size measured by transmission electron microscopy was in the 2–5nm diam ran ...
In this paper, we describe two methods for computerized analysis of cryo electron tomography reconstructions of biomolecules. Both methods aim at quantifying the degree of structural flexibility of macromolecules and eventually resolving the inner dynamics ...
Thirteen different commercial TiO2 powders with specific surface areas varying from 9 to 335 m/g and with isoelectric points (IEP) from 3 to 7.5 were investigated for their catalytic activity in E. coli inactivation. The TiO2 samples zeta potential, attenu ...
The specialized type III secretion (T3S) apparatus of pathogenic and symbiotic Gram-negative bacteria comprises a complex transmembrane organelle and an ATPase homologous to the F-1-ATPase beta subunit. The T3S ATPase HrcN of Pseudomonas syringae associate ...
Electron microscopy (EM) has played a central role in our current understanding of the mechanisms underlying the pathogenesis of several amyloid diseases, including Alzheimer's disease, Parkinson's disease, and prion diseases. In this chapter, we discuss t ...
The issue of protein dynamics and its implications in the biological function of proteins are arousing greater and greater interest in molecular biology. In cryo-electron tomography experiments one takes several snapshots of a given biological macromolecul ...
