CEP: November 2013

This month's SBE supplement on biochemical engineering honors Danny I. C. Wang, Institute Professor of Chemical Engineering at the Massachusetts Institute of Technology and founding chair of the Society for Biological Engineering (SBE). The articles in this supplement, written by several of his former students, describe his leadership, pioneering spirit, teachings, entrepreneurship,and scientific research, as well as present their own current research that was inspired by Danny's teachings and vision. Other topics in this issue include energy efficiency in cooling systems; bin design; and single-use equipment for biomanufacturing. Also read about the latest developments in biotechnology, nanotechnology and energy.


A poll conducted by the Univ. of Texas at Austin (www.utenergypoll.com/newsroom) in September found that the average American does not have a good understanding of energy issues. What’s saddening is that many don’t seem to care much about energy. Although 62% of the respondents claim energy issues are important to them, less than half say they are interested in energy issues, and only 28% find energy exciting.

Optimize Energy Use in Industrial Cooling Systems

Heat Transfer
Michael R. Muller, Michael B. Muller, Prakash Rao
Potential energy savings for chilled-water cooling systems are often overlooked. A detailed review of the cooling system along with the appropriate temperature and flowrate measurements will help you identify ways to cash in on these savings.

Consider Single-Use Equipment for Biomanufacturing

Fluids and Solids Handling
Roman Rodriguez
Traditional stainless steel equipment is increasingly being replaced with disposable units in new and existing processes alike, enabling more flexibility, higher efficiencies, and lower costs. Follow the guidance offered here to determine the most-effective single-use approach for your facility.

Ten Steps to an Effective Bin Design

Back To Basics
Eric Maynard
Before choosing a bin and hopper for your bulk solids application, the flow properties and characteristics of the powder or bulk material must be known. Use this ten-step approach to determine the optimal bin design for your process.

SBE Supplement: Biochemical Engineering - Cell-Free Bioprocessing

SBE Special Section
James Swartz
The ability to exploit a cell’s contents and capabilities unimpeded by cell walls opens new opportunities for the field of biochemical engineering. Cell-free biology could become the basis for making products from hydrogen to cancer vaccines and more.
