This research investigates the effects of bending on the electrical, optical, structural and mechanical properties of flexible organic photovoltaic (OPV) cells. Bulk heterojunction organic solar cells were fabricated on ...

This study presents the results of an experimental study of the effects of cassava leaves carbonitriding on the microstructure, hardness and abrasive wear behaviour of AISI 1065 and AISI 1070 steels used for barite mining ...

This work presents the responses of optical properties and mechanical failure of layers of stretchable organic electronic structures under tension using analytical, simulations, and experimental techniques. The interfacial ...

Epoxy, a thermosetting polymer due to its attractive properties, has been widely used in many industries as a coating material such as the oil and gas industries. This study provides an insight into the corrosion behavior ...

Femtosecond lasers represent an electromagnetic field with field intensities approaching and even exceeding atomic binding field. When irradiated on a target, the material responses change from linear to nonlinear within ...

Failure of offshore oil and gas pipelines occurs under certain conditions due to some applied mechanical forces. These conditions constitute a potential threat to the integrity of in-service life span of the pipelines ...

Gold nanoparticles were synthesized by reducing aqueous chloroauric acid (HAuCl4) with three different bacteria. Various microorganisms were verified to see how feasible they will be in synthesizing gold nanoparticles. ...

Many building collapsed cases have been reported throughout the West African regions. It is recorded that during some of these subsidences, many lives are lost and the vast majority end up in hospitals and clinics with ...

This thesis focused on an implantable encapsulated structures that can deliver localized heating and controlled released of prodigiosin (PG) (a cancer drug) synthesized by bacteria (Serratia marcescens (subsp. marcescens)). ...

Implantable Bio-Micro-Electro-Mechanical Systems (BioMEMS) represent a new class of devices that can provide localized cancer drug delivery by the combined effect of chemotherapy and hyperthermia which gives it an advantage ...

Current standard of care treatment modalities for early-stage breast cancer typically involve mastectomy or lumpectomy followed by radiation therapy to remove any residual cancer cells. Although mastectomy has a low ...

Wearing of mining tools leads to high replacement costs, machine downtime and loss of business opportunities. This work was however, aimed at improving the wear resistance of AISI 1065 and 1070 proeutectoid steels used for ...

Patients living with sickle cell disease are perpetually plagued with painful crisis episodes, caused by vascular occlusion. Over time, this leads to oxygen deprivation and the eventual damage of starved tissues and organs. ...

The study explores the investigation of the chemical composition, microstructure and mechanical properties of steel and cement mortar used in reinforced concrete. The compositions and mechanical properties of the locally ...

In this dissertation two main themes are explored. In the first part some phenomenologies of light transport across the ZnO/Al/ZnO (ZAZ) thin film multilayer structures are investigated. The multilayered ZAZ thin film ...

This study presents the results of a combined experimental and theoretical study of the strength, fracture toughness and interfacial properties of natural fiber-reinforced earth-based composite materials. The composites, ...

This research work presents the results of analytical studies of effects of pressure and adhesion energy on the interfacial properties of cold welded and laminated surfaces in organic and Hybrid Organic/Inorganic electronic ...

The study of the structures and properties of organic materials for organic photovoltaic (OPV) applications and their interrelationships is a rapidly growing field of research, involving interdisciplinary efforts at the ...

This dissertation shows the use of material science and engineering approaches in developing solutions to problems in the life science with focus in nano and micro-particles for the detection and treatment of cancer. It ...

When a well is drilled, the equilibrium in-situ stress is changed. In order to support the stress relief induced by the drilling and to prevent hydrocarbon influx into the cavity, the borehole is filled with a fluid. These ...
