Optimization of Fasp for Li-Ion Cathode Material Production
… combustion to speed the process of creating the materials for lithium-ion cathodes, more specifically the NCM-811 variation of the lithium-ion batteries. This study aims to identify key factors in improving the powder production of the FASP system. One way it aims to do this is by creating a CFD …

The potential contribution of industrial symbiosis to greenhouse gas emissions mitigation
Decarbonising energy-intensive material production processes as quickly and effectively as possible is a key challenge for policy-making to mitigate climate change. The global production of bulk materials such as steel, cement, paper, and aluminium has almost tripled over the past three decades. …

Development of a pavement life cycle assessment tool utilizing regional data and introducing an asphalt binder model
… burdens of five phases in the life cycle: material production, construction, maintenance, use, and end-of-life. The framework is incorporated into a user-friendly software tool that can be used to facilitate LCA for pavements. As a data-driven methodology, LCA is highly dependent on the …

The theoretical relevance of an updated Marxian theory of commodity in economics
How does material production become socially recognised in capitalism? This is a fundamental question to be addressed in capitalist production, since material production takes place privately and independently in a global and atomistic system. This thesis shows that the question is tackled by Marx …

Holistic modeling and evaluation of material recovery from materially-complex end-of-life vehicles
Material recovery is a key lever to promote a sustainable materials recycling system. By capturing materials from end-of-life products and substituting primary with secondary material production, society can reduce the depletion of natural resources and prevent the accumulation of valuable …

Development of a pavement life cycle assessment tool for airfield rehabilitation strategies
… for airfield pavements. LCA-AIR incorporates the material production, construction/maintenance and rehabilitation, and use phases in the analysis. Standard indicators from TRACI are used to quantify these impacts based on two functional units (square yard and pounds-mile traveled). To assess and …

Psychogeographical displacement: Responses to exploitation of urban space in the visual arts
… their relationship with space by responding with material production of housing and art, which they accomplish by building without exploiting the environment the way the manufacturing of commodities often does. The relationship is also revealed through residents’ critical reactions to specific …

Glycoprotein mimetic materials - synthetic methods and study of viral inhibition properties
The human body houses some of the most unique materials on the planet and is a promising source of bioinspiration. The high molecular weight and glycosylation of mucin-type glycopeptides make them challenging to produce or even mimic. This material production challenge is one of the key limiting …

Evaluation of geological CO 2 storage involving adsorption on mining wastes from coal processing
… damage which greatly increases the costs of raw material production. Within the scope of this thesis an approach for sorptive CO2 storage in coal mines was developed. By using mining wastes for CO2 immobilization and stowage of mining cavities, this technology combines CO2 storage with subsidence …

Uranium Enrichment Signatures of Fluorinated Epoxy
Accounting for the production of fissile material is an important component of enforcing the international non-proliferation regime. However, while there are well defined forensic techniques for estimating and verifying the production of plutonium, there are currently no such techniques for the …
