In this study, engineering reaction kinetics of sulfite and sulfite-anthraquinone pulping of black spruce wood are investigated.

Boron carbide was produced on tungsten substrate in a dual impinging-jet CVD reactor from a gas mixture of BCl3, CH4, and H2.

The phase and morphology studies of the products were made by XPS, XRD,micro hardness and SEM methods. XPS analysis showed the existence of chemical states attributed to the boron carbide phase, together with the existence of oxy-boron carbide speci

For a large subset of reactions (viz. abstraction or insertion of oxygen), this technology is based upon the use of oxygen carriers.

Rather, these technologies would require the further adoption of energy storage technologies, such as water splitting, to convert the energy produced into chemical bonds for later use to match demand.

These emulsions were stable for several minutes. Inclusion of 1% of the non-ionic surfactant Tween 80 led to the generation of C/W emulsions which were stable for over 1 hour after ceasing sonication, in which all of the carbon dioxide present in the system comprised the dispersed phase.

Abstract:

Thesis: Ph. D., Massachusetts Institute of Technology, Department of Chemical Engineering, 2015.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (pages 164-184).<br>With the cost to discover and develop a drug now estimated to exceed $2 billion, the pharmaceutical industry is in search of innovative and cost-effective ways to reduce process footprint, minimize lead times, and accelerate scale-up. One path to achieving these goals is in the adoption of continuous processing. Among the many advantages offered by the use of continuous flow systems is the ease of in
