The ongoing COVID-19 pandemic has shaken the global financial system and caused great turmoil. Facing unprecedented risks in the markets, people have increasing needs to find a safe haven for their investments. Given that the nature of this crisis is a combination of multiple pr…
Erken Bizans Dönemi'nde, Konstantinopolis, Doğu Roma İmparatorluğunun ekonomik, siyasi ve dini merkezi olarak gösterdiği gelişmeyle MS 7. yüzyıla kadar sürecek bir ilerleme tanımlamaktadır. Özellikle MS 6. yüzyıldan itibaren, saray bünyesinde yer alan mücevher atölyeleri ve büyü…
This dissertation investigates overall the impacts of the modern extractive mining industry on the lives of local people in the region of Kedougou, and in particular in the villages of Sabodala and Faloumbo. It explores also, how the utilitarian narratives about corporate mining…
Monodispersed gold particles of various sizes, morphologies, and internal structures were prepared by the reduction in homogeneous solutions of tetrachloroauric(III) acid (HAuCl4) with iso-ascorbic acid. The mechanisms responsible for their formation were investigated with speci…
Le gisement d'or etudie est encaisse dans la partie ouest de la granodiorite de Tiouit d'age proterozoique moyen a superieur (entre 750 et 650 Ma?). La granodiorite est mise en place dans une serie volcanosedimentaire du proterozoique inferieur et fait partie de la boutanniere d…
This thesis examines the influence of institutional investors in the activities of large, publicly traded gold mining companies. As key sources of financing and dominant shareholders in company stocks, institutional investors have pushed for the maximisation of shareholder value…
This thesis describes the development of gold, rhodium and palladium complexes incorporating a series of fluorinated N-heterocyclic carbene (NHC) ligands (NHC = 1,3-bis(fluorophenyl)imidazol-2-ylidene, fluorophenyl = 4-fluorophenyl (NHC-1), 2,4-difluorophenyl (NHC-2), 2,6-difluo…
Formaldehyde is a chemical used widely in the manufacture of building materials. A remarkable example is represented by the Lucite two-step Alpha technology for the large scale production of methyl methacrylate (MMA), the essential building block of all acrylic-based products. E…
The application of ICP-MS to the fields of proteomics and genomics has arisen in part due to its ability to detect and quantify trace levels of S and P, which are major constituents in proteins and nucleic acids respectively. The development of collision/reaction cell technology…
This Thesis reports the synthesis, purification and characterisation of gold nanoparticles (NPs) functionalised with a monolayer of hydrazone ligands in order to perform post-synthetic manipulations of the NP-bound monolayer exploiting dynamic covalent chemistry. NP post-synthet…
Silica nanoparticles are effective fluorophore carriers with high potential in imaging, diagnostics, and therapy. The particles are resistant to drastic change of environmental conditions (pH, temperature etc.) and insulate the dyes so as to protect them from photobleaching. Sil…
Recently established as an excellent activator for π-systems, efforts made in gold chemistry have increased enormously, resulting in a new ‘Gold Rush’ in chemistry. This thesis is a small contribution to it. There are two main aspects dominating the following chapters: gold cata…
Altın ve petrol piyasalarının analizinin yapıldığı bu çalışma üç bölümden oluşmaktadır. Çalışmanın ilk bölümü olan giriş bölümünde, çalışma kapsamında incelenen konular ile ilgili ön bilgiler yer almaktadır. Çalışmanın ikinci bölümünde altın piyasaları, altının özellikleri, düny…
The Yellow Pine Mining District, located in central Idaho, has produced nearly 900,000 ounces of gold and significant amounts of silver (> 2.5 million ounces), antimony (50,000 tons) and tungsten (845 K units). Midas Gold Inc., who is currently exploring the district, has def…
Correct diagnosis of disease is essential in the effort to save and improve lives. Point of care (POC) diagnostics are in-vitro tests that assist in patient diagnosis and can be used at the location of patient care. POC diagnostics are easy to use and provide near-instant readou…
In-Between Pleats is a research project constituted by a series of case studies, historical research, a short intensive pleating apprenticeship, and live performances. The research objective emerged through the exploratory making of pleats. It is to create new thinking about ple…
The hydrogenation of β-ketoesters over chirally modified Ni catalysts is a celebrated and thoroughly researched example of an enantioselective heterogeneous catalytic reaction. Enantioselective heterogeneous processes, although extremely attractive in terms of fewer complication…
