Dr. Janet deGrazia teaches students in her Creative Technology course how to be aware of false technology or faulty reasoning. Clyven the transgenic mouse is a great example of faulty technology that could lead someone to believe the mouse can actually communicate in a human format. |
The course, called Creative Technology/Social Impact of Technology, was first developed 20 years ago by the faculty as a science option for non-engineering majors. Enrollments soon escalated to current heights of more than 400 students per semester. The department constantly revamps the course to keep up with technological advances. The current curriculum delves into the fields of energy, biotechnology, nanotechnology, and computer hardware, with topics ranging from traditional and alternative energy techniques to pharmaceutical and agricultural applications of biotechnology to ethical topics such as cloning. Nanotechnology subjects from nanotubes and nanofabrication to computer subjects including transistor logic, microprocessor chip fabrication, and displays also are covered in the class.
In an effort to foster an interactive atmosphere despite the large class size, student-held clickers are used extensively and a class discussion board is available for students to post and discuss questions. Short movie clips are shown and demonstrations are given to further enliven the atmosphere. Students are also encouraged to look up related topics in the news and submit them for possible class discussion.
Students learn not only about the science itself, but also about the scientific process. They are taught to look critically at arguments and identify the logical fallacies of which unsound arguments are comprised. They are also taught about the peer-review process and what makes peer-reviewed articles more reliable than information drawn from internet sources such as Wikipedia.
For students whose interaction with science and engineering is minimal, the Creative Technology course is a window into some of the most exciting scientific advances in the recent years. Through this class, we hope to excite students and maybe even inspire them to delve further into the world of science we find utterly fascinating.

Look in the science sections of web sites and newspapers these days and you are likely to find at least one article having to do with materials science and engineering (MSE). Researchers in the field examine the structures and characteristics of materials at the nano scale with hopes of better understanding macroscopic properties and creating new materials with desired properties. With our increasingly sophisticated means of studying and manipulating materials at the molecular level, materials science and engineering is becoming a larger and larger focus in industry and academia. The University of Colorado Boulder created the new, interdisciplinary graduate program in materials science and engineering (MSE) in October 2010.
The CU MSE program, directed by chemical and biological engineering Professor Chris Bowman, involves nine departments on the CU Boulder campus. Participants bring expertise from the fields of engineering, chemistry, biology and physics, with MSE topics ranging from polymer synthesis and characterization to photovoltaic materials to biomaterials. Doctoral students enroll in a particular department, taking classes in this and other departments and pursuing cross-disciplinary research supervised by one or more MSE-affiliated faculty members. In addition, a new graduate program, admitting students directly into MSE rather than a department, will begin accepting student applications in Fall 2011. The goals of the MSE program are to enhance research and education in materials fields while at the same time benefitting participating faculty, students, and the university.
An MSE program web site is currently under construction. For additional information, contact Chris Bowman at christopher.bowman@colorado.edu

Global warming has pushed the subject of carbon capture and sequestration to the forefront of science and engineering. As CO2 levels in the atmosphere continue to climb above historical levels, researchers are looking into ways to remove carbon from industrial output streams. The current benchmark technology for capturing CO2 from power plant flue gas is amine absorption, a solvent scrubbing technique. Unfortunately, using this method to remove 90 percent of the CO2 requires up to 30 percent of the total power produced by the plant. The CO2 capture cost for this solvent scrubbing method is $40-100/ton of CO2, resulting in a more than 50 percent increase in the cost of electricity (COE). The DOE NETL Sequestration Program seeks to decrease the COE increase to less than a 35 percent by 2020 with costs targeted at just $20-25/ton of CO2. To meet these goals, an improved method of capturing CO2 needs to be developed.
Rich Noble and Doug Gin of the Department of Chemical and Biological Engineering along with partners Los Alamos National Laboratories and the Electric Power Research Institute were recently awarded a $3.8 million, three-year grant from the Department of Energy to investigate membrane separations for CO2 capture. Membrane separations are less energy-intensive, require no phase change, and typically provide low-maintenance operations. Performance is dictated by the membrane permeance and selectivity for the components of interest. They are using gelled ionic liquid membranes in an effort to obtain membranes with higher fluxes and thus lower costs.

Heidelberg Instruments and the University of Colorado recently completed an exclusive option agreement for a CU technique that shrinks the circuitry of nanodevices, enabling the creation of smaller computer chips and other nanodevices. The method was developed by Chris Bowman along with Tim Scott and Robert McLeod of the Department of Electrical, Computer, and Energy Engineering.
To create nano-scale circuitry, the patent pending nanolithography method uses tightly focused beams of blue light to record lines and dots thousands of times smaller than the width of a human hair onto a substrate such as silicon. This initial step occurs in all types of nanoengineering, but the new system developed by the CU team uses a second beam of ultraviolet light to "erase" the edges of the pattern, resulting in much smaller structures. In turn, this enables the manufacture of smaller computer chips, solar cells and other nanoscale devices.
“University of Colorado is one of the leading R&D centers making major inroads in nano scale technology development,” said Alexander Forozan, Head of Global Business Development at Heidelberg Instruments. “We are thrilled to work with CU’s outstanding staff and look forward to a continuing and long-standing relationship.
“We are excited to have Heidelberg as a partner for this technology,” added Ted Weverka, a licensing manager at the University of Colorado Technology Transfer Office. “Heidelberg’s technical know-how and market savvy ensure a strong future for this invention.”
Heidelberg Instruments is a world leader in production of high precision maskless lithography systems. These systems are used for direct writing and photomask production by some of the most prestigious universities and industry leaders in the areas of MEMS, BioMEMS, Nano Technology, ASICS, TFT, Plasma Displays, Micro Optics, and many other related applications.

Dr. Joel Kaar joined the Chemical and Biological Engineering faculty as an assistant professor in August 2010. Prior to joining the department, he was a postdoctoral researcher in Professor Sir Alan Fersht’s laboratory at the Medical Research Council Centre for Protein Engineering at Cambridge University in England. He completed his PhD in chemical engineering in 2007 under the supervision of Dr. Alan Russell at the University of Pittsburgh, where he also received his BS in chemical engineering.
Kaar’s research broadly focuses on the convergence of chemical engineering and protein engineering with pertinent problems related to sustainability, chemical weapons defense, and medicine. He is specifically interested in the study of protein structure and function in extreme environments as well as at material interfaces. This work has important implications towards the use of proteins, namely enzymes, for green chemistry and the preparation of biomaterials with sophisticated functions.
Joel has enjoyed his short time living in Boulder so far and looks forward to becoming a part of the CU community. Although a lifelong Penn State fan, he is particularly excited about learning about the sports traditions at CU and cheering on the Buffs.
The department also recently hired Dr. Sai Reddy, who will join the department in August 2011 as an assistant professor. Sai completed his PhD at the Swiss Federal Institute of Technology in Lausanne, Switzerland and is finishing up his postdoctoral research at the University of Texas. His research is in experimental system immunology, which is at the interface of engineering and immunology.

Max Peters, gifted leader and educator, colleague, and friend to many, passed away on June 20. He came to the University of Colorado Boulder in 1962 to be dean of the College of Engineering and Applied Science, and held this post until 1978, when he returned to teaching full-time. He also served as department chair for a few years, and finally retired in 1987.
As dean of the college, Max was very involved with financing and constructing the current Engineering Center. He also established several avenues through which faculty and alumni could be recognized for exemplary research, service, or leadership, including the Distinguished Engineering Alumni Award, which recognizes outstanding graduates and friends of the college.
Max continued his research and teaching activities while dean. He taught courses ranging from chemical engineering senior design to the freshman introductory course, while his research focused on air pollution, especially controlling oxides in the atmosphere. He may be best known for his widely used textbook, "Plant Design and Economics for Chemical Engineers," which had its 5th edition published by McGraw-Hill Book Company in 2002.
Students who worked under Max’s tutelage knew that competition and fun went hand in hand. As dean, he shared his competitive nature with his students, whom he raced yearly during Engineering Days. Creating races that only he could win, Max manipulated the rules before and during the races. His antics ranged from announcing suddenly that the winner had to be wearing an unusual hat and then producing the wildest hat possible, to declaring that the winner had to finish last, next to last or third from last and then running backwards, turning summersaults, and running around trees with the baffled students following. “I was the only one who knew the rules,” he said. “But the students didn't get mad; they just tried to outwit me.”
Max graduated from Pennsylvania State University in 1942 with a BS degree in chemical engineering. Two years later, he enlisted in the Army, choosing infantry training as a ski trooper in the 10th Mountain Division, A Company, 85th Regiment. While on assignment in Italy, he was awarded the Silver Star Medal, two Bronze Star Medals, the Purple Heart, and several other honors. Following WWII, he returned to Penn State to earn his MS and PhD in chemical engineering in 1947 and 1951, respectively. His first faculty assignment was with the University of Illinois.
Max’s leadership, research and teaching brought him many awards, most notably his election to the National Academy of Engineering in 1969. He also was chosen by AIChE in 1983 as one of 30 Eminent Chemical Engineers in the United States. Among his other awards were the Robert L. Stearns award and the CU Faculty Service Award. He was also named Distinguished Alumnus of Pennsylvania State University in 1974. He received the Centennial Award in 1993 from ASEE for Outstanding Service in Engineering Education and the Centennial Medal from the University of Colorado Boulder's College of Engineering and Applied Science in 1994, which recognized him as one of the top 100 individuals in the college's 100-year history.
A memorial service was held earlier this month. In lieu of flowers, contributions can be made to the Max S. Peters Graduate Fellowship Fund by writing a check to the CU Foundation with Max Peters on the memo line. Checks can be mailed to: Engineering Development, 422 UCB, Boulder, CO 80309.
A Tribute to Max S. Peters
By Bill Krantz, CU faculty member, 1968-2000
This has been a year filled with some sadness owing to the loss of two of my most loved mentors, Klaus Timmerhaus and Max Peters. Max was my department chairman when I was an undergraduate at the University of Illinois. Although I never had Max as teacher, he had a profound influence on my life. During my senior year he called me into his office and asked “Where are you going to graduate school?” I replied that I was not going to graduate school but to industry. Max immediately responded with the dictate to apply to three universities whose names he provided. Max had a way of “advising you” that made you feel like you were in the 10th Mountain Division in which he served as a Sergeant during WWII! I followed his advice and pursued Ph.D. studies at Berkeley during which time my interest in pursuing an academic career developed. When it came time to interview for an academic position, I applied only to CU where Max was now dean of the College of Engineering and Applied Science – I wanted to work for the man who changed my life so positively!
Shortly after I arrived at CU, Max called me with another dictate: “Be at the gym at noon on Wednesday – you are on our four-mile relay team.” I told Max that I was not a runner. His immediate response was “You are now!” On the appointed afternoon Max told me to run a mile with him. Since I was 29 and he was 48, I figured I could keep up with him. I was able to stay with him for a mile, after which I collapsed. As I lay on the floor I saw him take off like a rabbit – he had been ‘sandbagging’ so that he could pull me through the mile. I was so intimidated that I quit smoking that day after having smoked since I was 15. It then took me two years before I could keep up with Max. Thank you Max for making me aware of physical fitness and undoubtedly giving me several more years of a healthy life.
My feelings for Max are best summarized in a poem that I wrote for the plaque that was presented to Max upon his retirement in 1987, which reads as follows:
There came a day in the year 1962,
When Max Peters decided what to do.
Because this young man dearly loved to ski,
Colorado became a much stronger University!
As a leader and a skier he was hard to beat.
His example taught many of us how to compete!
To our College he leaves a rich legacy and tradition,
His charge and challenge – “Get into the competition!”

Klaus D. Timmerhaus, an accomplished educator, colleague, and friend passed away in February. He joined the CU faculty in 1953 after earning his BS, MS and PhD degrees in chemical engineering from the University of Illinois. Timmerhaus was multifaceted in his career, having received high honors for his research and numerous accolades for his teaching and administrative service. Passionate about running, Timmerhaus supported the CU track team for more than 50 years.
Among his teaching honors are the Hazel Barnes Prize, President’s Teaching Scholar, Charles A. Hutchinson Teaching Award of the College of Engineering, Tau Beta Pi Outstanding Professor Award in engineering and the George Westinghouse Award of the American Society for Engineering Education for outstanding contributions to teaching. In total he was honored with more than 48 teaching awards, but Klaus’ favorite honor was bestowed upon him by his students: “Dr. T, the Meanest Professor” award. Clearly he bonded with his students!
Klaus’ research took him to the top of his field, leading to his election to the National Academy of Engineering in 1975 and his 2008 recognition as one of the Top 100 Chemical Engineers of the Modern Era. Klaus’ contributions to cryogenics science and practice have been honored by the American Institute of Chemical Engineers, the Samuel C. Collins Award of the Cryogenic Engineering, and the 1968 Alpha Chi Sigma Award.
In addition to teaching and research, Klaus helped steer the administrative side of the college by serving as associate dean, director of the Engineering Research Center, and chair of both the aerospace and chemical engineering departments. During this time he was also involved with more than 10 scientific and professional societies.
To honor the memory of Klaus Timmerhaus, gifts can be made to the Klaus D. and Jean L. Timmerhaus Scholarship Fund by writing a check to the CU Foundation with Timmerhaus Scholarship on the memo line. Checks can be mailed to: Engineering Development, 422 UCB, Boulder, CO 80309.
Klaus Timmerhaus – My Friend and Mentor
By Bill Krantz, CU faculty member, 1968-2000
Klaus Timmerhaus had a profound impact on my professional development. Klaus was influential in helping me obtain my first research grant via the BUILD program between CU and the University of Illinois for which he served as the Director. In 1977 he encouraged me to take an academic leave to serve as a Program Director at NSF, an experience that greatly expanded my horizons in terms of my research interests. Klaus also encouraged me to get involved in professional service, in particular the Southwestern and Rocky Mountain Division of the American Association for the Advancement of Science for which I served as President.
Klaus was an indefatigable worker–he was always working and could always add another activity or commitment to the busy schedule he had. I can recall that when my wife and I were married in Boulder in 1968 he was the only faculty member to attend our wedding ceremony carrying a briefcase! However, Klaus did have a weakness–chocolate chip cookies–he absolutely loved them! Last December when we learned that Klaus was nearing the end of his life, my wife and I knew what to bring him for a Christmas present–a batch of homemade chocolate chip cookies. Since we left for my job in Singapore right after the holidays, I knew when we gave him these cookies that we probably would never see Klaus again, at least not on this earth.
Thank you Klaus for all that you did for me and for so many other faculty and students at CU. We will miss you.
<top>CU has launched a comprehensive campaign called Creating Futures. This $1.5 billion campaign to support the University of Colorado’s people, places, and programs will foster transformations in learning and teaching, discovery and innovation, community and culture, and health and wellness throughout our four campuses.
Donors provide a crucial margin of excellence for CU. With your support, we’ll be better equipped to turn ideas into action. State support has declined substantially: fewer than 30 years ago, State of Colorado funding represented nearly 30 percent of CU’s budget; it now represents less than 6 percent.
Creating Futures means changing lives through the power of education, the promise of discovery, and our partnership with community, leading the University of Colorado toward a better tomorrow. The Department of Chemical and Biological Engineering is a leading force in discovery and education and benefits greatly from private support.
