Effect of Pressure on the Performance of Organic Light Emitting Devices Fabricated by Cold Welding
(2013-04-15)
Analytical and finite element models were used to simulate additive cold welding patterning processes. The effects of adhesion, pressure, thin film (layer) thickness and dust particle modulus (between the contacting surfaces) ...
The Effect of Bitumen Coatings on the Corrosion of Low Carbon Steels (API 5l X65)
(2013-05-12)
The corrosion behavior of uncoated and cut-back bitumen coated X65 Steel samples are being investigated in environments of different pH (2, 3, 4 and 7). Immersion tests were carried out on the samples at 25oC. The comparison ...
Failure Mechanisms of Epoxy Coatings in Pipelines
(2013-05-12)
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 ...
Bioinspired Design
(2013-05-12)
Bioinspired design involves the use of concepts observed in natural biological materials in engineering design. The hope is that the leveraging of biological materials in the engineering domain can lead to many technological ...
Clay Filtration of Microbes and Fluoride
(2010-06-07)
Consumption of contaminated water may result in several water-borne diseases, including hepatitis, typhoid, cholera, dysentery and other diseases that cause diarrhoea. One of the ways this problem can be prevented is by ...
Biosynthesis of Magnetic Nanoparticles for Cancer Detection and Treatment
(2011-12-15)
Chemical and physical methods for the synthesis of magnetic nanoparticles for cancer detection and treatment often involve toxic chemicals, high cost and the formation of non-stable nanoparticles. This prompted the development ...
Improving the Wear Resistance of Barite Mining Tools
(2014-12-15)
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 ...
Annealing Heat Treatment of Organic Material for Controlled Bulk Heterojunction Solar Cells
(2013-05-15)
The morphology of active layers of organic solar cells plays crucial roles in achieving good performing devices with longer life span. The process of fabricating these devices involved post deposition thermal annealing, ...
Bacterial Remediation of Polyethylene
(2011-12-15)
Improper disposal of commodity plastics e.g. polyethylene (PE) in the environment causes land pollution, soil infertility, is unsightly and poses dangers to plant and animal life. The current effort describes the bacteria ...
Fracture Mechanics Approach for the Maintenance of Offshore Oil and Gas Pipeline
(2014-12-15)
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 ...
