This work focuses on experimental study of cross-property connections that link up effective linear elastic and electrical conductive properties of heterogeneous materials. Such connections are especially useful when one property (electrical conductivity) is easier to measure th…
Many chemical and physical factors govern the mobility of metal contaminants in soils and clay systems; some of these chemical factors include mineralogical composition, cation exchange capacity, organic matter content, pH and the ionic strength of soil water. This makes underst…
A rotating diffusion cell (RDC) has been used to study the kinetics of extraction of the transition metals cobalt (II), nickel (II), copper (II) and zinc (II) from sulphate solutions into either of two extractants held in n-heptane; di-(2-ethylhexyl) phosphoric acid (D2EHPA) or …
The present study was designed to look at the changing role of metals in the Early Bronze Age economies of North Syria and Anatolia through an analysis of textual, typological, and metallurgical data. This objective is achieved through the study of metal artifacts, specifically …
Arsenic (As) is a well-known human carcinogen. However, it is a poor mutagen, as such it has been proposed that its carcinogenicity may stem from its ability to interfere with or impair epigenetic machinery. For my dissertation work I investigated the effect of arsenic exposure …
Estimating the relative contribution of heavy metals and nutrients loads from diffuse and point sources and various hydrological pathways is a major research challenge in catchment hydrology. Understanding of the transfer, loads and concentration of these loads in basins is usef…
Powder Bed Fusion (PBF) is one of the Additive Manufacturing (AM) techniques, in which metal powders are used as feedstock. AM process enables the production of lightweight structures, design freedom in 3D printed parts, short cycle time, etc. AM made part properties are affecte…
Recently emerged perovskite materials show superior features like high efficiency, defect tolerance, facile synthesis, bandgap tunability and wide color gamut over their rivals in photonics applications. On the other hand, metals have interesting characteristics as they go small…
It goes without saying that the necessity and utility of knots in our everyday lives is crucial. Humanity used them to symbolise religious beliefs (endless knot in Buddhism) and countless forms of art throughout history (Roman mosaics, Celtic art etc). However, we know them bett…
Dynamic windows enable electronic control of light and heat flow and demonstrate potential for increased energy efficiency in buildings and improved well-being for the people inside them. Despite four decades of research and development, the traditional approaches to dynamic win…
Changes in social organization can be studied through several different avenues one of which is through mortuary patterns. Here we will be looking at changes in social organization during the Late Bronze Age and Iron Age in Northern Europe using mortuary and osteological data. I…
When debris is discarded, it becomes integrated into the geologic processes and identity. We all leave objects behind after consumption. A statement in history lingers, told by our physical traces and material remains. These components reveal a collective, as well as personal id…
For over a century, Sudbury (Ontario, Canada) has been a major copper-nickel metal smelter centre. Emissions of acidifying compounds and metal particulates beginning in the 1880s damaged thousands of lakes and watersheds in the region. Emission controls introduced in the 1960s a…
