A silver coated hollow glass fiber with a core diameter of 250 μm is studied for beam transport and nonlinear optical applications at 800 nm using a femtosecond Ti:sapphire laser. To reduce the losses, the inner glass surface of the waveguide is coated with a thin film of silver…

Since its foundation between 1410 and 1414 the University of St Andrews has acquired what can be considered to be ‘artefacts of significance’. This somewhat nebulous phrase is used to denote items that have, for a variety of reasons, been deemed to have some special import by th…

The production of silver-loaded zeolites either by ion exchange method or by isomorphous substitution of silver ions into zeolites frameworks and their antimicrobial activity is presented. Silver-loaded zeolites produced by ion-exchange in this work include silver-exchanged zeol…

This study investigates the feasibility of using TTO and Ag+ alone and in combination either as free or liposome encapsulated agents. Based on the minimum lethal concentration (MLC), the fractional lethal concentration index (FLCI) showed that treatment with unencapsulated combi…

This dissertation is about the fabrication of monodispersed (same size, shape, composition, structure, etc.) silver nanoparticles in gas media and their optical characterizations such as optical absorption, nonlinear optical response and plasmon assisted fluorescence. The first …

The objectives of this dissertation were to: 1) characterize the effect of several different silver nanoparticles (AgNPs) on the ammonia oxidizing bacterium (AOB) Nitrosomonas europaea and investigate possible mechanisms for toxicity, 2) test the effects of consumer product AgNP…

The coinages of the North Aegean have long been viewed as an anomaly: large and extensive silver issues produced in a region thought to be a mere backwater of the Greek world. For this reason, modern scholarship has tended to assume that they were originally intended as a conven…

This paper examines how the Wixárika, or Huichol, as they are more commonly known to the outside world, have successfully engaged in a decade-long struggle to save their ceremonial homeland of Wirikuta. They have fended off a Canadian silver mining company’s attempts to dig mine…

The Upper Cretaceous mineralizations, located in northeastern Turkey, are the largest sources of base metals in the country. Vein-type and the volcanogenic massive sulfide-type deposits (VMS) are present and both are closely associated with felsic volcanism of Upper Cretaceous a…
