The work presents the results of the studies of Co-Cr-Mo casting alloys used in the production of frame casts of removable dentures, crowns and bridges in dental prosthetics. The studies were performed on four Co-Cr-Mo alloys of different contents of Mo, W and other additives. Electrochemical tests were performed, which aimed at examining the corrosion resistance of the alloys and observing the...

Distributed, Web-based Microstructure Database for Brain Tissue. (May 2000) Wonryull Koh, B.S.; B.S., The University of Texas at Austin Chair of Advisory Committee: Dr. Bruce H. McCormick A finite element model of the cerebral cortex enables a structured visualization of its gross anatomy and provides access to the neuronal databases associated with each finite element of tissue. Partitioned by...

To characterize the effect of shearing on function of fibrillar adhesive microstructure, friction and shear-related changes in pull-off force of a biomimetic polyvinylsiloxane mushroom-shaped fibrillar adhesive microstructure were studied. In contrast to a control flat surface, which exhibited pronounced stick-slip motion accompanied with high friction, the fibrillar microstructure demonstrated...

[1] The first near coincident measurements of acoustic backscatter and temperature/velocity microstructure confirm theoretical predictions that oceanic turbulence scatters sound. Not only are acoustic backscatter at 307 kHz and turbulent microstructure unambiguously correlated on a patch-by-patch basis, but measured scattering amplitudes agree with theoretical predictions for scattering from tu...

The term microstructure refers to the complete internal structure of a material on the micro, nano and atomic scales. On one hand, it records the entire history of a material’s processing and structuring (casting, forming, heat treatments, but also crystal growth, etc.) through its phase composition, defect structure and morphology. On the other hand, all properties (stiffness, formability, con...

This paper discusses the design and the fabrication procedure of a novel design of microaccelerometer. The proposed design consists of a seismic mass suspended with quadri-beams and the patterned displacement transducers using piezoelectric thin films. The electromechanical system model is presented to illustrate the interactions of material characteristics, amplification circuit designs, and m...

A microstructure consisting of ultrafine grained (UFG) ferrite with average grain size of ~ 0.7 µm and dispersed nano-sized carbides was produced by cold-rolling and tempering of the martensite starting microstructure in a low carbon steel. Subsequently, fine grained dual phase (DP) steel consisting of equiaxed ferrite grains with average size of ~ 5 µm and martensite islands with average size ...

This study was performed to recognize the loess texture in Golestan Province, Iran using the microstructure analysis according to the electron microscopic images. Loess microstructure study allows for investigating the characteristics of particle shape, fabric, cement and porosity in microscopic images. In recent years, computer analysis has been replaced with manual calculation due to its high...

In this paper we investigate the effect of microstructure irregularities and applied strain on backward Brillouin scattering by comparing two photonic crystal fibers drawn with different parameters in order to minimize diameter and microstructure fluctuations. We fully characterize their Brillouin properties including the gain spectrum and the critical power. Using Brillouin echoes distributed ...
