Polyvinylpyrrolidone (PVP) is suitable alternative to the polyvinylidene fluoride (PVDF) often used binder in electrode of supercapacitor. The major problem of the PVP is the part it plays in the conductivity of ions in ...

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 ...

Existing data show that Portland cement material production contributes ~8% to the global CO2 emissions. This is detrimental to the environment and can lead to global warming. It is therefore pertinent to develop alternative ...

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 ...

One of the unintended impacts of crude oil exploration is the pollution of agricultural land and aquatic resources when there is accidental oil spillage. The environmental effect of this has resulted in untold hardship to ...

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 ...

Since the pioneering report of the discovery of graphene in 2004 by Novoselov et al, scientists and researchers worldwide have carried out in depth investigations in this new family of carbon because of its myriad properties ...

This study was carried out under various experimental conditions and rate of dye adsorption such as the solution pH, the adsorbent preparation concentration, and contact time to assess the potentiality of Kentucky coffee ...

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 ...
