Progress report on the catalyst layers for hydrocarbon-fueled SOFCs

Numerical Modeling of Single-Chamber SOFCs with Hydrocarbon Fuels

A two-dimensional numerical model of a single-chamber solid oxide fuel cell SCFC operating on hydrocarbon fuels is developed. The SCFC concept is a simplification of a conventional solid oxide fuel cell in which the anode and cathode are both exposed to the same premixed fuel-air mixture, and selective catalysts promote electrochemical oxidation of the fuel at the anode and simultaneous electro...

Concept Assessment of a Hydrocarbon Fueled Rbcc-powered Military Spaceplane

The U.S. Air Force has long been interested in the next-generation space launch capabilities that might be enabled by high-speed air-breathing propulsion. Since the early 1960's, studies have examined the application of ramjet or dual-mode scramjet propulsion to potential reusable military spaceplane (MSP) concepts. Perceived advantages include flexible basing, flexible operations, hypersonic s...

Progress in the Development of E-Series Catalyst Technologies for the Selective Hydrogenation of Acetylene in Various Hydrocarbon Streams

The effect of sufficient barrier layers on hydraulic fracturing design efficiency in one of the Iranian South hydrocarbon reservoirs

Hydraulic fracturing and matrix stimulation are two major methods of the reservoir stimulation. Hydraulic fracturing, which is the newest technique and technically more complex, is very useful in low permeability reservoirs. Although it has been used widely in hydrocarbon production wells, it is a new method in Iran. In this paper, the effect of sufficient barrier layers on hydraulic fracturing...

Ethics review as a catalyst for progress.

There are several points where ethical decision-making has become paralyzed and inefficient as the field of Alzheimer's disease study has advanced. The focus of this review is to highlight these points and several lines of research that can inform ethical decision-making. The goal is to identify barriers and to move toward solutions. Examples of other fields of study that can be particularly us...
