Simulation of a proton exchange membrane fuel cell

A. Hasan, S. Guo, M. Wahab

Performance prediction of a proton exchange membrane fuel cell (PEMFC) has been studied using a multiphysics-based numerical simulation. The simulated geometry was a simple…

Disappearance of stacking fault in colloidal crystals under gravity

A. Mori

After reviewing a previous work on the disappearance of a stacking fault in the hard-sphere (HS) system confined between the top and bottom flat walls under gravity, we present…

Improved arc discharge setup for synthesis of single and multi walled carbon nanotubes

M. Haneef, Jamil Abdo, Syed Ullah, S. Waqar, Fayaz Hussain, Ashraf Ali

This paper presents development of a laboratory scale setup for production of CNTs by arc discharge process in an argon gas environment. The main problem with existing lab scale…

Cadmium as an environmental pollutant influence of cadmium on chlorophyll content of canadian wonder beans (phaseolus vulgaris)

Hocine Benabid, Mohamed Ghorab

Studies carried out in different plant species have revealed that Cd is strongly phytotoxic and causes growth inhibition and even plant death, although the mechanisms involved in…

Three-dimensional active earth pressure behind pile and screen by applying the kinimatics theory

H. Benyaghla, M. Meksaouin, L. Belabed

Two theoretical models very simple in calculation of active earth pressure of prism of three-dimensional rupture mobilised behind pile or screen in translation, were proposed…

Physical effects of natural pozzolana on alkali-activated slag cement

L. Zeghichi, Z. Benghazi

The alkali-activated slag (AAS) cement is an interesting building material, confronting to the new economical and ecological challenges. In order to enhance its physical…

Repair and rehabilitation of corrosiondamaged concrete elements using FRP composite wraps

H. Karpate, H. Wheat, J. Jirsa, D. Fowler, D. Whitney

Reinforced concrete structures have been wrapped to provide strength and confinement in the presence of seismic loads. The wrapping of structures as a means of mitigating…

Heat transfer modeling of multilayer reactive foil

R. Liu, S. Guo, X. Qiu, J. Wang

Nanostructured reactive foils have attracted a great deal of interest recently due to their unique mechanical and thermal properties. Reactive thin foil can be used as a…

Evaluation of bulk orthotropic properties of heavy plywood bridge decking

C. Adam, H. Milner, B. Ahmed

This paper devises a method for modelling the bulk orthotropic properties of heavy plywood bridge decking described in Australia as Bridgewood, which can be customized in terms of…

Thermoplastic elastomers including ground tyre rubber in a thermoplastic matrix

J. Cañavate, P. Casas, F. Carrillo, F. Nogués, X. Colom

Disposal of end of life tyres is regulated in many countries. The enormous amount produced every year needs the research of new ways of recycling. A common practice previous to…

Electron tunnelling in metallic beads systems and slow electric relaxation

A. Tekaya, R. Bouzerar, V. Bourny, I. Tekaya

We study numerically and theoretically the electrical behavior of individual steel beads and the contact between 2 adjacent beads within a granular system. Due to the thin…

Bioadsorption of suspended and dissolved particles from coal washery effluent onto fluted pumpkin seed shell biomass

M. Menkiti, T. Chime, O. Onukwuli

Fluted pumpkin seed shell, an abundant and inexpensive natural resource in Nigeria, was used as a precursor to adsorbent production for the removal of suspended and dissolved…
