Fluorapatite-zinc oxide (FAp-ZnO) composite nanopowders were successfully prepared via mechanochemical process. Characterization of the products was carried out by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) analysis, energy dispersive X-ray spectroscopy (EDX), and field-emission scanning electron microscopy (FE-SEM) techniques. Results revealed that in the absence of ZnO which produced by hydrothermal method, the single-phase FAp had high-crystalline structure with appropriate morphological features. Furthermore, after 5 h of milling in the presence of 5 wt.% ZnO, FAp-5 wt.% ZnO, composite nanopowders with no impurity phase was obtained. Structural studies illustrated that the milling up to 5 h was not accompanied by a remarkable change in the structural features. Moreover, the gained composite powders presented an average crystallite size of about 40 nm for FAp. The FE-SEM observations indicated that the experimental outcome had a cluster-like structure which consisted of several small particles. Finally, results propose a new approach to prepare commercial amounts of novel FAp-based composite nanopowders with high quality and suitable structural and morphological features.

Mo and Cu Were Bonded Successfully by Means of Vacuum Diffusion Bonding. The Interfacial Structure of the Joints Was Studied by Scanning Electron Microscopy (SEM), Electron Probe Microanalysis (EPMA), Energy Dispersive X-Ray Spectrometer (EDS) and X-Ray Diffraction (XRD), the Mechanical Property Is Tested by Tensile Strength Measurement. The Results Showed that the Differentatoms Diffused to each other in the Bonding Process. A Mo-Cu Solid Solution Was Formed in the Joint and with No Intermetallic Compounds. The Tensile Strength of the Joint Increased with the Increasing of Temperature, however, while the Holding Time Increased, the Strength Increased in the First Stages and then Decreases. It Were Observed that the Fracture Mode of the Joints Was a Brittle Fracture.

Abstract Clay-Polyacrylate hybrid material was prepared from Montmorillonite (M) clay and polytrimethylol propane triacrylate (PA) using intercalation polymerization process. Characterization of the composite was done by x-ray diffraction (XRD), infrared (IR) spectroscopy, scanning electron microscopy (SEM) and energy dispersive x-ray (EDX) techniques. The results show the successful intercalation of PA in the M moiety. The MPA hybrid material was then blended with a polyolefin elastomer, Engage. Tensile and dynamic mechanical properties were measured on the polymer-filler composite and the results showed interaction between the treated clay and the base polymer. There was a significant improvement in modulus, tensile strength and elongation at break of the base polymer as compared to the composite prepared with the untreated clay.

Nanoparticles, particles of size 10-9have a high potential as water, waste water and air pollution treatment. In this research, nanoscale iron particles were synthesized by reduction of Fe2SO47 H2O by NaBH4at low temperature to avoid oxidation during the process. Characterization of the particles based on particle size, material structure, surface morphology and the composition of forming element was done by transmission electron microscopy (TEM), X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray spectometry (EDS), respectively. Surface area and magnetic character was measured by BET surface area and vibrating sample magnetometry (VSM), respectively. Morfological observation showed that structured core-shell of size < 44 nm and shell of size ~ 3 nm with saturated magnetization value ~ 132 emu g‾¹ has been formed.

This is presentation number 696 from the 2018 ECS/Aimes international meeting within the symposium D01: Semiconductors, Dielectrics, and Metals for Nanoelectronics 16. This talks covers joint work on ferroelectric films and devices between Tokyo Electron, SUNY Polytechnic Institute, and Notre Dame. Polarization is correlated to structural characterization using electrical measurements combined with Grazing Incidence X-Ray Diffraction. Test devices were fabricated and characterized to demonstrate and investigate how ferroelectric HfZrO can be used for various electronic applications including memory, logic, and neuromorphic devices.

Studies of the nature of a surface, either metallic or nonmetallic, in the past, have been limited to the instrumentation available for these measurements. In the past, optical microscopy, replica transmission electron microscopy, electron or X-ray diffraction and optical or X-ray spectroscopy have provided the means of surface characterization. Actually, some of these techniques are not purely surface; the depth of penetration may be a few thousands of an inch. Within the last five years, instrumentation has been made available which now makes it practical for use to study the outer few 100A of layers and characterize it completely from a chemical, physical, and crystallographic standpoint. The scanning electron microscope (SEM) provides a means of viewing the surface of a material in situ to magnifications as high as 250,000X.
