Strength and Fracture of Earth-Based and Natural Fiber-Reinforced Composites
(2010-12-15)
This study examined the mechanical properties of earth-based materials that are relevant to the future development of affordable housing. Earthcrete structures were produced by mixing various proportions of laterites, clay ...
Gold Nanoparticle for Medicine
(2010-12-15)
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. ...
Modeling of Cold Welding and Lamination of Organic and Hybrid Organic /INORGANIC Structures
(2011-12-15)
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 ...
Abrasive Wear Studies of Pack Cyanided Mild Steel (PCMS)
(2011-12-15)
This work aimed at using processed cassava leaves to pack cyanide mild steel (MS) under different treatment conditions and investigating the wear properties of the pack cyanided mild steel (PCMS). Pack cyaniding (PC) of a ...
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 ...
