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 ...

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 ...

Materials selection is done regarding to the availability, cost and performance of the candidates. In buildings, cement is the material that is widely used, even though it is releases co2 (estimated about 7% of the worldwide ...

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 advent of nanotechnology together with Biomedical Microelectro-Mechanical Systems (BioMEMS) for improved efficacy in treatment of cancer has resulted in the development of an implantable biomedical device for localized ...

The study explores the potential effects of the remote application of cyclic magnetic field to the female anopheles mosquitoes that carry malaria parasites. The goal is to develop a theoretical basis that can guide the ...
