Osteoporosis has become an important health and economic problem of our aging western society. This metabolic illness leads to a net bone loss and to a deterioration of trabecular architecture. Motivated by the fact that osteoporosis may also result in a d ...
GaN/AlN quantum-dot superlattices grown by molecular-beam epitaxy on silicon (111) or sapphire (0001) substrate have been investigated using high-resolution transmission electron microscopy, photoluminescence, and photo-induced absorption spectroscopy. Und ...
A comparative characterization of crystal structure, morphology, sizes, and orientation in Ca phosphate precipitation from aqueous solutions, the mineral phase in bones, and mineral deposits on cardiac valves has been performed by high-resolution transmiss ...
A comparative image simulation and transmission electron microscopy (TEM) study has been addressed in order to assess whether NiAl intermetallic undergoes a crystalline-to-amorphous transformation directly induced by the cascade. For this purpose, an NiAl ...
The high-pressure freezing (HPF) technique was applied to the cryo-immobilization of alginate gels and the quality of the freezing analyzed on a TEM by comparison of the segregation pattern of samples of decreasing thickness. Dynamic simulations of heat tr ...
A transmission electron microscopy of pyramidal inversion domains induced by Mg doping in MOVPE and bulk GaN is presented. Based on high resolution observations and EDX analysis, two atomic models are proposed for the Mg-rich (0001) inversion domain bounda ...
High resolution transmission electron microscopy (HRTEM) and X-ray energy dispersive spectroscopy (EDS) were applied to study the structure of hydroxyapatite (HAP) coatings deposited by plasma spraying on different substrates (Cu, Cr, Ni, NaCl, BaF2). Coat ...
Calcium alginate beads were thermally treated at temps. ranging from 25 DegC to 130 DegC for periods of up to 30 min. Important modifications to the structure of the alginate beads were shown to be a function of the temp. and period of incubation at each t ...
Two mutations in the alpha-synuclein gene (A30P and A53T) have been linked to autosomal dominant early-onset Parkinson's disease (PD). Both mutations promote the formation of transient protofibrils (prefibrillar oligomers), suggesting that protofibrils are ...
Collagen type I displays a typical banding periodicity of 67 nm when visualized by atomic force or transmission electron microscopy imaging. We have investigated collagen fibers extracted from rat tail tendons using atomic force microscopy, under different ...
