Chemists and Engineers

12 Replies

What would happen to innovation in chemical technology if we had a more intimate comingling of chemistry and the engineering sciences?  What effect would there be on the stream of chemists graduating into the world if more schools had a chemical engineer on the chemistry faculty? Could a single engineer on the faculty actually make a difference in altering the direction of the boat a few degrees?

Why is such a change desirable? One way to change the trend of deindustrialization and economic repositioning of manufacturing out of North America is to stimulate innovation in the industrial sciences. To do this we can rely on business leaders individually to formulate strategic plans to upgrade plants and processes by way of step changes in technology. But for business leaders, the calculation for such a change must also take into account the alternative of moving production to another country. Many times it is easier and faster to move production to China rather than taking a gamble on the invention of better technology. A large amount of pharmaceutical manufacturing has been shifted to China, Mexico, and India for this very reason.

To rely on business leaders (top down) to ramp up innovation really means that one is relying on the market. While letting the marketplace drive the economics and distribution of manufacturing has a certain appeal to purists, the global marketplace is highly distorted by government and taxation. Letting “pure” market forces govern innovation as the sole driver is to bet all of your money on a horse that limps.  Why not find ways to stimulate innovation with an improved stream of chemical innovators and a renewed urgency?

Universities do this all of the time. But it is my sense that other disciplines perhaps do this better. It is all too easy for we chemists to invent a reaction or composition, publish it, and then move on to the next outcropping of opportunity. We do this thinking that surely somebody will pick up the ball and run it to the end zone of commerce.

But for any given paper published in SynLett or JOC or ______, the likelihood of commercialization is low. It is not automatically the role of academic science to drive its work towards commercialization. That has been the role of engineering. 

What has been lacking is more significant early overlap of the two disciplines. For a chemist to truly be a part of bringing a transformation to the manufacturing scale, the chemist has to begin thinking about how to prepare the chemistry for the big pots and pans. This is what the art of scale-up is about. And in scale-up, the practice of chemistry has to overlap with the practice of engineering.

Industry already provides for itself in this way by training chemists to do scale-up work. This kind of work has always been beyond the scope of academic training.  But what if there were a course of study wherein chemistry faculty and students could more thoroughly address the problems of chemical manufacture? What if engineering concepts would be allowed to creep into the training of chemists?

Chemistry faculty would begin writing grants for process oriented research. Schools without engineering departments might start hiring the odd engineer or two in an effort to “modernize” the chemistry department.  Gradually, a department might become known among recruiters and donors for producing a strain of BS, MS, and PhD chemists who are already adapted to process research.

It is important to stress that the goal is not to plop conventional engineering curriculum into the chemical course of study.  That will not work. But what is possible is to build a minor in industrial chemistry applications. This pill will be easier to swallow for the P-chemists because in short order it would be apparent that chemical engineering is heavily loaded with physical chemistry.

I have tried to make a case that one way to make a positive influence in chemical innovation in North America is to begin a grass-roots effort to stimulate the culture of chemistry. I believe that providing an avenue of study that includes early exposure to engineering and process economics will stimulate many more students and faculty to make significant contributions to entrepreneurism and industry.

The Chemistry Curriculum

21 Replies

It is time to have a frank talk about the fundamental merits of the college chemistry curriculum. This plan of study has remained substantially unchanged for decades (see comment by bchem). Certainly minor changes occur through nudges and bumps here and there pertaining to details. But in the last generation has there been a dialog or debate on the fundamental assumptions of the common curriculum? And I refer specifically to the ACS certified curriculum, which has been the gold standard across the country. Major changes that I have been witness to mainly accomodate an increased emphasis on biochemistry or new computerized instrumentation. 

The undergraduate chemistry curriculum is a very logical and thorough survey of the three pillars of chemistry- Theory, synthesis, and analysis. This covers the fields of inorganic, organic, physical, analytical, and biochemistry. Along the way we teach a few other areas of specialty by way of electives.

The current program of chemical pedagogy is certainly true to itself. There is genuine concern and care to avoid dilution of the content and over-inflation of grades, generally. The core domains of the subject are sorted out and given special consideration. Much work has been done to spark interest in the field and textbooks seem to be written quite well as a rule.  Resources like J. Chem. Ed. are a continuous stream of clever tools and tricks to make the subject more plain.

Our colleges and universities have been quite good at churning out chemical scholarship. And students are given scholarly exposure in their learning program. Not surprisingly, scholars are very good at producing more scholars.

But has the academy been keeping up with the role of chemistry in the world?  Just look around. How many CEO’s and upper executives in the top 100 chemical companies are chemists? I have not seen this statistic tabulated. But I am confident that relatively few chemists populate those ranks. Those that do often arise through marketing or finance channels.

But why should they? The field of chemistry attracts people interested in science, not business. Chemical educators have a responsibility to educate chemical scientists with a minimum proficiency in the field.  That requires a minimum number of semester hours of coursework within a 4 year period. There is only so much a department can do and so much a student can absorb.

Yet, the purpose of a college education is to prepare a student for a productive life. A learning program that is internally consistent but blind to the needs of the external world is a fantasy. Have we come to value programmatic tidiness more than practicality?

Chemistry is a highly practical field. It involves problem solving and production. Chemists make stuff. Chemists solve problems. Chemists are specialists in the transformation of matter. But chemists do not operate in a vacuum. They do their work for organizations, and there is the rub.

By training, chemists are woefully prepared to function outside the laboratory. And as a direct result, chemists are poorly prepared to leave the lab and function elsewhere in the organization.  Traditionally, education in the organizational arts has been considered on-the-job training. In a sense this is not unreasonable. How can educators anticipate the needs of a student 5 years into the future? 

What is under appreciated by educators and students alike are the many opportunities that will follow for a chemist in industry. Many if not most chemists will come to a fork in the road in their careers. Will they stay in the lab or will they go to the business side? Usually, the path to greater opportunity in a business organization is the business side. Technical sales, customer service, marketing, procurement, management, etc.

I am not proposing that chemistry faculty teach coursework that cover such material. I am trying to suggest, however, that chemistry departments take a closer look at what an industrial career really looks like and try to anticipate a few needs that will arise as a result of this career path. Advisors can talk to students about the possibility of a business minor. An accounting or marketing class could be very helpful for a student who is uncertain about his/her career path. These are painless actions that can be of great use to a graduate.

But there is more than the passive approach of suggesting alternatives to undergrads. There is a more active approach that would definitely serve the needs of students and society alike.

Elective coursework covering intellectual property and patents, business law, the regulatory world (TSCA, EPA, OSHA, CERCLA, REACH, etc.), industrial hygiene, and perhaps most importantly an introduction to chemical engineering. This last item I cannot overemphasize.  Chemical engineering includes the basics of unit operations, process economics, thermodynamics, and controls. I would offer that the whole package could be called Industrial Chemistry. 

There are junior college programs for chemical operators that do provide exposure to some engineering concepts. But this isn’t necessarily for management track graduates.

I would offer that the department with an industrial chemistry program would be very successful in job placement as well as attracting new majors.  Comments?

 

Struggle

Something happens to some people when they transition to adulthood. They gradually quit becoming and focus on being. To be is to plant a stake in the ground and pronounce what you stand for. To become is to keep looking for better ground. To become is to invite disruption. To be is to find a comfortable spot.

To be is to live in the moment. To become is to delay gratification.

As one grows older, the interest in becoming naturally fades as opportunities to be are exhausted. The trick to staying vital and interesting is to keep finding ways to become. That is the struggle.

For those newbies just coming out of school into the fabulous world of Big Time Chemistry, you have an interesting time ahead of you. You’ll soon learn that your crisp new diploma is really just a backstage pass down the rabbit hole of The World, Inc.  Your brain is now as sharp as it’ll ever be … well, after some well deserved R&R. Your capacity to spend long hours in the lab will never be greater.  And, your skin has thickened to the abuses from too many years in college. The cleat marks of rabid and unscrupulous profs posturing for tenure will scab over and vanish. Now is your chance to plant your cleats anywhere you please.

For those going into industrial slots, there is yet much to learn. Whereas in school your cohort is confined to a narrow age group, in the world you’ll land in a place filled with workers of all ages. The biggest surprise of all may be the slow realization that perhaps you’re not the only person of Ability in the room. Not all of the really bright people stay in academia or even went to college.

You’ll be able to examine people in various stages of career growth and in various capacities. There is a vast difference in corporate cultures and in time one adapts to the demands of the Machine. This Machine requires much of its people. All company Machines are constructed around a core. This core is the accounting system.  Many people are dedicated to the upkeep of this part of the Machine.  Scientists fresh out of school are often unaware of the critical importance of non-scientist staff pulling the handles and twiddling the knobs of the Machine so it can keep operating.

I happen to think that chemical plants are really fascinating places whose sophstication and importance is frequently misunderstood. Yes, they are often maligned as unattractive blights on the landscape. But from the technology pespective, chemical manufacturing is a rich part of our technological heritage and more of us need to make that point to our communities. 

There are many paths in a good and righteous career in chemistry. Some choose to stay in R&D. Others choose the dark side and enter business development or the even darker side of supply chain management (just kidding, mostly). Many will discover fascinating specialties they never new existed like scale-up, kilo-lab, pilot plant operations, or production support. Then there is quality control, analytical services, technical support, or environmental health and safety.

There are many industry segments that use chemists, so try not to get fixated on just one. It is quite possible to have a good life outside of pharmaceuticals. For students who are interested in grad school, there is polymer chemistry or a variety of material sciences. Polymer science and rheology is fascinating and there is a huge industry out there making polymers. But no matter what you pick, make certain it is something that you really dig. Then it is less of a job and more of a passion.

Chemistry on Mars

As I live and breath. The space community has gotten serious again about chemical analysis of Martian soil. NASA is very much driven by physicists and engineers, so it is nice to see chemistry get some flight time.  Why don’t more chemists elbow these physicists out of the way to put packages on rockets? I guess we are insufferable ground pounders.

The Phoenix Lander which, to NASA‘s great credit, has successfully landed in the North polar region of Mars, is equipped with an array of analytical instruments and wet chemical apparatus for on-the-spot analysis of soil samples. Among the devices on board is a Swiss-made Atomic Force Microscope. This device will provide direct microscopic imaging of Martian soil samples. In true Swiss fastidiousness, it has multiple cantilevers for redundancy. I’m sure it keeps good time as well. 

The Canadian Space Agency has contributed a meterological station on the lander.

The lander was constructed by contractor Lockheed Martin.

Given that the lander contains hazardous chemcials for the analyses, somebody is going to have to dispose of the hazardous waste after 90 days. I hope it is properly placarded.  \;-)

 

 

Poorer Living from Better Things

I’m not an apologist for the chemical industry. Chemical industry has a checkered past in many ways. The pesticide, petrochemicals, and mining industries have left a deep and abiding foul taste in the mouths of many communities. In a previous era, heavy industry has fouled rivers, lakes, air, and ground water. It has lead to illness, death, and loss of livelihood to many people.

But in the modern era much of this wanton issuance of hazardous industrial material into the air and waters has been halted or greatly diminished. At least for the US, Canada, and the EU. And it is not because industry suddenly found religion. The “regulatory environment” became so compelling a liability cost factor that industry set its mind to engineering plants into compliance. 

I would make the observation that today, the major chemical health issues before us are not quite as much about bulk environmental pollution by waste products. Rather, I would offer that the most important matter may have to do with the chronic exposure of consumers to various levels of manufactured products. High energy density foods, particularly, high fructose corn sweeteners; veterinary antibiotic residues, endocrine disrupters, smoking, highly potent pharmaceuticals, and volatiles from polymers and adhesives to name just a few.

Modern life has come to require the consumption of many things.  A modern nation must have a thriving chemical industry to sustain its need for manufactured materials. It is quite difficult and isolating to live a life free of paint and plastics or diesel and drugs. Choosing paper over plastic at the supermarket requires a difficult calculation of comparative environmental insults. Pulp manufacture vs polymer manufacture- which is the least evil? I don’t know.

Our lives have transitioned from convenience to wretched excess. Our industry has given us an irresistable selection of facile ways to accomplish excess consumption. Individualized portions meter out aliquots of tasty morsels that our cortisol-stressed brains cry out for. These same portions are conveniently dispensed in petroleum- or natural gas-derived packages within packages within packages. These resource depleting disposable nested packages are delivered to our local market in diesel burning behemoths because some pencil-necked cube monkey decided that rotund Americans needed yet one more permutation of high fructose corn syrup saturated, palm oil softened, sodium salt crusted, azo dye pigmented, extruded grain product on Wal-Mart shelves.

Enough already.

Tornado Dreams

4 Replies

This afternoon over lunch hour at the plant I stepped outside and saw a rotating wall cloud just a few miles west. It is unusual for tornadoes to form this close to the mountains. I’ll admit that I was disappointed to not witness an actual funnel.  

At about the same time 15 miles NW near my home, a funnel cloud was spotted. From that location, my daughter reported that fellow middle school students were huddled under their desks for an hour waiting for the storm to pass. Another 15 miles north, my wife was busy herding elementary school students under their desks in what they call the “squat and scream” position. Sadly, a nearby town suffered a strike by a tornado that resulted in one fatality and a bunch of heavily damaged homes.

Imagine if the area that comprises what we refer to as the Middle East was an area that suffered tornado activity. That would be the area from Lebanon to Iran to Egypt.  It is fun to speculate how the Abrahamic religions might be filled with parables and stories detailing the wrath of God through the agency of a tornado.

Perhaps the exodus of the Israelites might have been aided by the thrashing of Pharaoh with a tornado rather than drowning as the parting seas collapsed. Or colorful tornado-related dream accounts of the end times in the New Testament’s Electric Koolaid Acid Trip of the Book of Revelations.

After the excitement it was back to business. Work is a seemingly endless carnival of intractable problems and sticky layers of nuance.

Synthetic Chicken- Regular or Extra Crispy?

8 Replies

While the rest of us were wasting our time sleeping or soaking in the spa, our ambitious food scientists have been steadily beavering away on the cultivation of chicken tissues. The goal is toward the mass production of chicken-like food.  Poulterer and Kentucky Colonel Harlan Sanders will be transformed into tissue farmer Dr. Sanders in a lab coat and goggles.

The mass production of tissue cultivated meats won’t happen anytime soon. However, it is something that is being investigated by serious workers in the field.

I have to admit that my unquestioning embrace of Progress is weakening. Nonetheless, interesting things are happening. Consider the work of Vladimir Mironov, Director of the MUSC Bioprinting Center at the Medical School, University of South Carolina in Charleston.  In an effort to get around the engineering problem relating to the construction of 3-D structured tissues, the idea of layering cells by ink-jet deposition was developed.

Who knows where this is going?  Mironov’s technology will be very expensive initially, so its application to the production of $4.59 pork tenderloin sandwiches at the local diner is some distance into the future. More likely than not, it will be used for the cultivation of designer transplant organs.

Eventually, some company with deep pockets will attempt to market engineered meats. I would venture to say that the marketing problem is nearly as big as the technology challenge. Wide acceptance into the marketplace will take a while. I wonder how the first ad campaign will take shape? PETA approved Beef-Like Steak Food. Marbling and tenderizing is already engineered into the “cut”. Marketing may eventually be its undoing.

Synthetic chicken fried steak with mashed potatoes and synthetic gravy. Genetically modified Roundup Ready corn on the cob boiled in reverse-osmosis purified water. HEPA filtered air in a kitchen cleaned with anti-microbial soaps. Mouths freshly gargled with hydrogen peroxide and bellies full of nutritional supplements. Lordy. Where are we going with this?
