Niobium Doped BGO Glasses: Physical, Thermal and Optical Properties
IOSR Journal of Applied Physics (IOSR-JAP) e-ISSN: 2278-4861. Volume 3, Issue 5 (Mar. - Apr. 2013), PP 80-87 www.iosrjournals.org Niobium doped BGO glasses: Physical, Thermal and Optical Properties Khair-u-Nisa1, Ejaz Ahmed2, M. Ashraf Chaudhry3 1,2,3Department of Physics, Bahauddin Zakariya University, Multan (60800), Pakistan. Abstract: IR- transparent niobium substituted heavy metal oxide glass system in formula composition (100-x) BGO75- xNb2O5; 5 ≤ x ≤ 25 was fabricated by quenching and press molding technique. Glassy state was confirmed by XRD. Density ρexp varied 6.381 g/cc-7.028 g/cc ±0.06%. Modifying behavior of Nb2O5 was corroborated by rate of increase in theoretical volume Vth, measured volume Vexp and oxygen molar volume -2 5+ 4+ VMO . Nb had larger cation radius and greater polarizing strength as compared to Ge ions. It replaced 4+ o Ge sites introducing more NBOs in the network. Transformation temperatures Tg, Tx and Tp1 were 456 -469 C ±2 oC, 516 -537 oC ±2 oC and 589 -624 oC ±2 oC respectively. In the range from room temperature to 400 oC -6 -1 -6 -1 the coefficient of linear thermal expansion α was 5.431±0.001*10 K to 7.333±0.001*10 K . ΔT = Tx-Tg and ΔTP1 = TP1-Tg varied collinearly with increase in niobium concentration and revealed thermal stability against devitrification. The direct bandgap Eg values lay in 3.24 -2.63 eV ±0.01 eV range and decreased due to impurity states of Nb5+ within the forbidden band. Mobility edges obeyed Urbach law verifying amorphousness of the compositions. -

Method: The materials used in the study were: 1) Macor, (Precision Ceramics UK) 2) BioMinF: 500gm of glass frit (Cera Dynamics Ltd, UK) and 3) Sylc: Sylc 45S5 glass (Velopex International, UK). An AquaCare Air Abrasion & Polishing System (Velopex) with a hand piece with a 0.8 mm diameter tip was used with a 2mm thick Macor sheet with a feed rate of 1 and an air pressure of 2 bar. The BioMinF glass was milled for 45 seconds in five batches each containing 100 gm of BioMinF frit using a milling machine (Gy-Ro Mill, Glen Creston, and London). The angular particles produced were separated using different sieves to produce <38 micron, 38-63 microns, 63-80 microns, 80-125 microns and 125-250 microns particle size(s) respectively. -

Lecture 4 (Pdf)
GFD 2006 Lecture 4: Interfacial instability in two-component melts Grae Worster; notes by Shane Keating and Takahide Okabe March 15, 2007 So far, we have looked at some of the fundamentals associated with solidification of pure melts. When we try to solidify a solution of two or more components, salt and water, for example, the character of the solidification changes considerably. In particular, the presence of salt can depress the temperature at which ice and salt water can coexist in thermal equilibrium. This has an important consequence for the growth of sea ice: unless there is some other mechanism for the transport of the salt field, such as convection, the growth of the ice is limited by the rate at which excess salt can diffuse away from the interface. Finally, we will discuss the morphological instability in two-component melts. We shall see that the solute field is destabilizing and can give rise to morphological instability even when the liquid phase is not initially supercooled. 1 Two-component melts 1.1 A simple demonstration We shall begin with a simple demonstration. Crushed ice at 0◦C is placed in a cup with a thermometer. We add a handful of salt at room temperature and stir briskly. The ice begins to melt, but what happens to the temperature? We notice that there is some melt water in the cup, which helps bring the ice and salt into contact, and see a fairly rapid decrease in the temperature measured by the thermometer: after a few minutes, it reads almost 10 C. -

Individuals, companies, and industries all work to establish and accomplish authenticity for themselves and related stakeholders. As a marketing point for creating differentiation and singularity, authenticity has the potential to augment the value of a product above and beyond its promising functional, esthetic, or experiential significance. However, authenticity is a concept with heavily debated characteristics, and it is not well understood in its market manifestations. Academic work on authenticity remains vague in terms of both its definition and its marketing relevance. -

Biology Chemistry III: Computers in Education High School
Abstracts 1-68 Relate to the Sunday Program Biology 1. 100 Years of Genetics William Sofer, Rutgers University, Piscataway, NJ Almost exactly 100 years ago, Thomas Hunt Morgan and his coworkers at Columbia University began studying a small fly, Drosophila melanogaster, in an effort to learn something about the laws of heredity. After a while, they found a single white-eyed male among many thousands of normal red-eyed males and females. The analysis of the offspring that resulted from crossing this mutant male with red-eyed females led the way to the discovery of what determines whether an individual becomes a male or a female, and the relationship of chromosomes and genes. 2. Streptomycin - Antibiotics from the Ground Up Douglas Eveleigh, Rutgers University, New Brunswick, NJ Antibiotics are part of everyday living. We benefit from their use through prevention of infection of cuts and scratches, control of diseases such as typhoid, cholera and potentially of bioterrorist's pathogens, besides allowing the marvels of complex surgeries. Antibiotics are a wondrous medical weapon. But where do they come from? The unlikely answer is soil. Soil is home to a teeming population of insects and roots, plus billions of microbes - billions. But life is not harmonious in soil. Some microbes have evolved strategies to dominate their territory; one strategem is the production of antibiotics. In the 1940s, Selman Waksman, with his research team at Rutgers University, began the first ever search for such antibiotic producing micro-organisms amidst the thousands of soil microbes. The first antibiotics they discovered killed microbes but were toxic to humans. -
