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 ...

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 ...

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 ...

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 ...

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 ...

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. ...

Our ability to power modern airplanes and land based engines depends largely on the thrust generated most importantly by aero engines. Over the past 30 years material cost has become an important factor, especially in ...

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 ...

Mesoporous materials have generated a lot of interest over the past few decades owing to their wide range of applications in catalysis, separation, drug delivery, sensors, adsorption, photonics, nanodevices etc. To realise ...

This research focuses on the design of a robust but flexible prodigiosin eluting stent coating for possible coronary cardiovascular implant. When coated with the drug embedded polymer matrix, the stent would be expected ...

This paper presents the use of multilayered chitosan films incorporated with antimicrobial agent, potassium sorbate to enhance effective food packaging. In this study, potassium sorbate was incorporated into multilayer ...

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 ...
