This article deals with a method of obtaining materials in the Ti-Al system. Research was carried out in accordance with the phase diagram of the system state. It was established, that both single-phase and multiphase systems, containing finely dispersed intermetallic compositions of phases Ti3Al, TiAl and TiAl3, are formed. Additionally, it was found that the pure finely dispersed (coherent-sc...

This research study was conducted to identify team-level coordination issues and to make strategies that help in overcoming these hurdles between Global Software Engineering (GSE) teams. In GSE projects, a steady flow of communication and coordination between the team members is required throughout the project. Communication and coordination make top in the list of challenges currently faced by...

Heat transfer during flow boiling in minichannels and microchannels is intimately linked to the liquid-vapor phase distribution in the channels. The vapor phase exists as nucleating bubbles, dispersed bubbles, elongated bubbles, an annular core, or all vapor flow completely filling the channel. Similarly, the liquid can exist as bulk liquid, slugs, thin film on the heated wall, or dispersed dro...

The aim of this study was to investigate the sol gel synthesis of HA/FA nanoparticles and the possible formation of TCP phase or unstoichiometric calcium deficient hydroxyapatite (CDHA) from the precursors with a Ca/P ratio of 1.62. In order to prepare the sol, the solutions of Triethyl phosphite, ammonium fluoride and calcium nitrate in ethanol were used respectively as P, F and Ca precursors....

We develop heterodyned dispersed vibrational echo spectroscopy (HDVE) and demonstrate the new capabilities in biophysical applications. HDVE is a robust ultrafast technique that provides a characterization of the real and imaginary components of third-order nonlinear signals with high sensitivity and single-laser-shot capability and can be used to extract dispersed pump-probe and dispersed vibr...

P. S. Hrnjak, S. P. Vanka A combined experimental and computational study will be undertaken to develop better understanding and control of dispersed two-phase flow in headers. First, we will examine misty flow regimes in headers using the refrigeration setup from Project 96 for which the liquid and vapor phase flow rates can be individually measured from five tubes distributed along the length...

An emulsion is a two-phase liquid system of two immiscible liquids, where the liquid with lower mass fraction is dispersed in form of small droplets in other surrounding liquid of higher mass fraction. Emulsions are widely used to produce sol–gel, drugs, synthetic materials, and food products. Based on the size of droplet, emulsions can be classified as micro and macro emulsion. Karbstein and S...
