Alternative Energy

Coke oven gas (COG) is a by-product when producing coke from coal. It is not always easy to make use of COG, causing waste of energy. Producing liquefied natural gas (LNG) is an efficient way of utilizing COG. The amount of hydrogen affects liquefaction process significantly, because its thermal...

Pyrolysis gas is a product of Biomass, Municipal Wastes or Coal gasification process that contains H2, CO as well as unreacted light hydrocarbons and heavy hydrocarbons such as tar. These undesired hydrocarbons diminish Pyrogas fuel value thereby making significant removal of the unwanted...

The notion of a fuel cell powered vehicle has captured the imagination of many as a clean/efficient alternative to the internal combustion engine. However, the capital cost of a fuel cell power unit is significant, and threatens to be a show-stopping hurtle. As such, many have looked to hybridize...

A systematic experimental study of the synthesis of copper oxide nanoparticles and nanoporous films is presented. Powders were made by flame spray pyrolysis method with end applications in the photoeclectrochemical production of hydrogen. Inhibited particle growth was observed for prticles made...

The use of electrospinning to generate one dimensional materials has garnered significant interest lately due to its inexpensive nature and the diversity of materials fabricated. Recently one dimensional materials have also been investigated to support catalytic nanoparticles to prevent aggregation...

The most popular catalyst for low temperature proton exchange membrane fuel cells (PEMFC) is platinum (Pt) nanoparticles supported on carbon [1]. One of the major issues concerning Pt nanoparticles is the very slow kinetics of oxygen reduction reaction (ORR) which limits overall performance of...

The large scale utilization of Nafion® in Direct Methanol Fuel Cell( DMFC) is still constrained by high methanol permeability and high temperature dehydration. The methanol crossover in DMFC can be minimized by using pervaporation membrane such as Poly-vinyl alcohol (PVA) due to higher water...

S-PEEK has been known as one of the promising candidates for fuel cell application since it has high thermo-oxidative stability and extraordinary mechanical properties as well as high cost effectiveness. However, the nanoscale structure and transport properties for S-PEEK have not been thoroughly...

The use of surfactant-directed mesostructured inorganic materials allows for the preparation of oxide frameworks as continuous transparent films with high inorganic-organic interfacial contact and the inclusion of diverse functional guest species. For example, mesostructured (10 nm) titania films...

Abstract: TiO2 nanowires were sensitized with CdS and CdTeS quantum dots which were grown using an in situ colloidal method using both conventional organic solvents and supercritical carbon dioxide (scCO2). No pretreatment of the TiO2 nanowires was required prior to nanoparticle generation. The...
