Abstract:

Surface functionalised silica materials have been prepared, followed by the extensive testing of their ability to remove metal ions from aqueous solutions. Modifications include ligand attachment and polymer grafting from the silica surface whilst the metals tested range from first row transition metals right through to the lanthanides and actinides. Characterisation of the materials produced has been of paramount importance for the understanding of the modification process and this is also extensively discussed. Atom transfer radical polymerisation (ATRP) has been used as the primary polymeri

Abstract:

This thesis describes hydrodynamic studies of the leach and solvent extraction stages of a Platinum Group Metal (PGM) hydrometallurgical flowsheet. The studies were motivated by the need to increase PGM throughput in Johnson Matthey’s PGM refining business. In the leach stage, key components in the feed are selectively dissolved using acids in a stirred tank before they are recovered by liquid-liquid (L-L) solvent extraction and finally purified. The work described in this thesis tackles four main areas: hydrodynamic studies of L-L PGM solvent extraction in both mixer and settler stages, whils

Abstract:

PGM concentrates contain more than just the platinum group minerals. They also concentrate three minerals pyrrhotite (Fe1 xS), pentlandite ([Fe,Ni]9S8) and chalcopyrite (CuFeS2). In a sample of Merensky concentrate tested in this study, these minerals account for half the concentrate. During smelting and converting these sulphides collect the PGMs in matte. Smelting produces a matte, the composition of which converting adjusts by oxidizing sulphur to SO2 and iron to Fe2SiO4 (fayalite). The objective of roasting a PGM concentrate would be to alter the composition of a concentrate, at lower temp

The dissolution kinetics of metal oxide particles of homogeneous composition follow a simple inverse cubic rate law. In chapter 3 the soft-centre kinetic model is developed which describes the dissolution of a monodispersion of particles, comprising two materials A and B, the former being more corrosion resistant than the latter. The particles are assumed to be richer in A at the surface and richer in B at the core thus leading to two phase dissolution kinetics.

Abstract:

In pressurised water reactors (PWRs), hydrogen overpressure is used to keep the corrosion potential below the threshold for onset of intergranular stress corrosion cracking (IGSCC) in type 304 SS. However, some regions may contain higher oxygen levels resulting in an increase in the potential. These 'dead space' regions are difficult to access and during refuelling; oxygen may become trapped in these locations. The objective of this study was to investigate the influence of PGM additions on IGSCC susceptibility of type 304 stainless steels (SS) in the sensitised state within PWRs. The work pre

There sulfonated particles were used for protein adsorpt

碩士<br>國立清華大學<br>化學工程學系<br>103<br>The development of biodegradable materials with elastomeric properties had become one of the most popular research topics in the past decade, and the need to produce new elastomeric polymers in large scale for a wide variety of applications had been ever increasing. Poly(glycerol sebacate) (PGS) is a novel elastomer, containing very good biocompatibility and biodegradability, has been applied to soft tissue regeneration to regenerate arteries. However, the fabrication of PGS requires high temperature and low pressure which limit its application in medicine and

Master of Science in Engineering - Engineering<br>The employment of an electrochemical process is an attractive alternative for the treatment of effluents. When dealing with solutions of low metal ion concentrations mass transport limitations are significant and large electrode surfaces are required. The use of a reactor containing a three-dimensional electrode is preferable as the surface area per unit volume is orders of magnitude greater than that of the familiar plate type reactor. A benchscale electrochemical reactor was designed and constructed to incorporate a cylindrical packed

Abstract:

This paper improves upon the methods for modelling the determinants of PGA TOUR golfers’ performance-based earnings by incorporating the most recent and accurate PGA TOUR statistics while controlling for year and individual fixed effects. Using a panel of golfers from the 2004 through 2011 PGA TOUR seasons, I find that a one standard deviation improvement in putting renders the average golfer 27 percent additional earnings; meanwhile, the same degree of improvement in driving distance offers only 14 percent more earnings. Even as PGA TOUR golf course yardages and driving distances continue to
