A Study of the Pre-Treatment Temperature of Lignocellulosic Butanols an Alternative Fuel (BIOFUEL) Produced from Bamboo using Clostridium Acetobutylicum
(2013-05-12)
Conversion of lignocellulosic biomass from bamboo (Bambusa vulgaris) to butanol is an important alternative energy source. In this work, bamboo was used as biomass feedstock for the production of butanol by the fermentation ...
The Role of Sulfur Oxidizing Bacteria on Corrosion of X65 Low Carbon Steels and its Mitigation Using Sodium Tungstate and Nickel Biocides
(2013-05-12)
Metals in service often give a superficial impression of permanence, but all except gold are chemically unstable in air and air-saturated water at ambient temperatures and most are also unstable in air-free water. Corrosion ...
Numerical Modeling of Wellbore Instability (SHEAR Failure) using Fracture Mechanics Approach
(2013-05-12)
Wellbore instabilities are responsible for 10-20% of the total drilling cost. It has been estimated that wellbore instability causes an annual economic loss of US$ 500 - 1000 million in the oil industry across the world. ...
Numerical Modeling of Wellbore Instability (TENSILE Failure) Using Fracture Mechanics Approach
(2013-05-12)
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 ...
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 ...
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, ...
Paclitaxel Loaded Polylactide-Co-Glycolide Acids for Coronary Artery Disease and Cancer Treatment
(2013-04-07)
The number one killer disease in the world is Cardiovascular Disease1. The most serious element of Cardiovascular Disease is Coronary Artery Disease. Currently, the main treatment for Coronary Artery Disease is stent ...
