Biodiesel is an attractive alternative fuel because of its nontoxicity and biodegradability properties. Biodiesel is produced through transesterification of vegetable oils’ triglyceride. It is obtained from vegetable oils or fats either by chemical or enzyme-catalyzed transesterification with methanol or ethanol. By using whole-cell biocatalyst immobilized within biomass support particles (BSPs...
BANYAY, GREGORY ALLEN, M.S., June 2006, Mechanical Engineering EXAMINATION OF POLYMERIC FOAM AS AN ON-BOARD VEHICULAR HPR HYDROGEN STORAGE MEDIA (113 pp.) Director of Thesis: Bhavin V. Mehta One of the major hurdles to be traversed before a Hydrogen Economy becomes practical, and therefore abundant, is the problem of its storage. An ideal HPR pressure vessel exhibits uniformly sized, spherical ...
Hybrid Ni/Al foams were fabricated by depositing electroless Ni-P (EN) coatings on open-cell Al foam substrate to obtain enhanced mechanical properties. The microstructure, chemical components and phases of the hybrid foams were observed and analyzed by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD), respectively. The mechanical proper...
Models currently used to simulate the impact behaviour of polymeric foam at high strain rates use data from mechanical tests. Uniaxial compression is the most common mechanical test used, but the results from this test alone are insufficient to characterise the foam response to three-dimensional stress states. A new experimental apparatus for the study of the foam behaviour under a state of hyd...

In this article a new structure of PEM fuel cell end plate is presented. The new structure is known as a honeycomb sandwich panel. Several properties of the presented structure, such as mechanical and thermal behavior, as well as its advantages and disadvantages are introduced. The aim of this paper is to reduce the weight of the while maintaining a better compression force on the PEM fuel cell...
