Image simulation has an invaluable importance for the accurate analysis of High Resolution Transmission Electron Microscope (HRTEM) results, especially due to its non-linear image formation mechanism. Because the as-obtained images cannot be interpreted in a straightforward fashion, the retrieval of both qualitative and quantitative information from HRTEM micrographs requires an iterative proce...

PURPOSE This study aimed to accurately analyze the relationship between calcium oxalate (CaOx) stone formation and the components of urinary nanocrystallites. METHOD High-resolution transmission electron microscopy (HRTEM), selected area electron diffraction, fast Fourier transformation of HRTEM, and energy dispersive X-ray spectroscopy were performed to analyze the components of these nanocr...

In this paper, meso-Tetraphenylporphyrin iron(III) chloride complex, Fe(TPP)Cl, supported on magnetic nanoparticles (PCMNPs) was synthesized and characterized by HRTEM, SEM, TGA, and FT-IR and VSM. The value of saturation magnetic moments of MNPs and PCMNPs are 68.5 and 60.3 emu/g, respectively. The SEM and HRTEM image were shown the uniformity and spherical-like morphology of nanoparticles wit...

Pink fibrous crystals within massive rose quartz from localities in California, South Dakota, Brazil, Madagascar, and Namibia were examined with high-resolution transmission electron microscopy (HRTEM) and analytical electron microscopy (AEM). This study reveals that the nanofibers in all samples are related to dumortierite. Selected-area electron diffraction (SAED) patterns and HRTEM images in...

We used vapor-liquid-solid (VLS) methods to synthesize discrete single-element semiconductor nanowires and multicomposition nanowire heterostructures, and then characterized their structure and composition using high-resolution electron microscopy (HRTEM) and analytical electron microscopy techniques. Imaging nanowires requires the modification of the established HRTEM imaging procedures for bu...

The past half century has seen explosive growth in the use of medical implants. Orthopedic, cardiac, oral, maxillofacial and plastic surgeons are examples of medical specialists treating millions of patients each year by implanting devices varying from pace makers, artificial hip joints, breast and dental implants, to implantable hearing aids. All such medical implants make use of special mater...
