According to the US Department of Energy, there is scientific evidence that CO 2 emissions from fossil fuels have caused climate change and that a reduction of these emissions is essential for reducing the risk of future devastating effects. At present, the leading technology for the post...

The transportation sector relies heavily on petroleum as a primary energy source, and currently faces challenges over high crude oil prices, volatility of the global oil market, and high levels of greenhouse gas (GHG) emissions [1]. As a result, a substantial effort has been taken in the United...

The heterogeneous oxidation of Zn(g) is a promising means of sustainably reducing CO 2 to CO in the two-step Zn/ZnO solar thermochemical cycle. Prior efforts on CO 2 reduction in the cycle have focused on the oxidation of solid or liquid Zn, and elucidate the need for faster kinetics. The rate of...

Understanding variability in excipient physico-chemical properties is becoming an important aspect of Quality-by-Design (QbD) drug product development. However, present experimental methods are only able to study a few physico-chemical properties on a few excipient lots due to time, cost, and...

There are significant differences in the methods employed by various organizations to estimate the cost of carbon capture and storage (CCS) systems for fossil fuel power plants. Such differences often are not readily apparent in publicly reported CCS cost estimates. As a consequence, there is a...

Oxidation of a metal (or metal oxide) by H 2 O and CO 2 followed by a regenerative high temperature thermal reduction of the resulting metal oxide is a promising method for using concentrated solar energy to produce syngas, a precursor for liquid fuels. For such a process to become viable, the...

Filter drying, also referred to as vacuum contact drying, is a process widely used in the pharmaceutical industry to remove water or organic solvents. The advantage of this process over other drying operations is that it can be used to dry solids that are sensitive to oxygen and temperature. The...

For over five decades Prof. Wang has devoted himself to biochemical engineering education, research, and technology creation. The course of his career illustrates the tremendous advances that have taken place in the field. His work helped propel technological innovation and development as it...

One of the important challenges in effective real time process management is the implementation of intelligent systems that can assist human operators in making supervisory control decisions, instead of simply sounding an alarm when process variables go out of range. Operator failures to exercise...
