Dr. Carlos Barrios, a colleague of mine from 3M St. Paul, asked over dinner at the last meeting of the Adhesion Society if I would like to take part in teaching a week-long course in polymers at the leading university in Colombia.
The course took place at Universidad Nacional in Bogota, Colombia. About 50 engineering students and several professional engineers from the community attended.
I taught the course in conjunction with Carlos and Omar Arias (Manager of Technical Service for 3M in Latin America).
We split the course into three segments: I taught “Fundamentals of Surface Energy and Adhesion”; Carlos taught “Recent Advances in the Science of Pressure Sensitive Adhesives”; and Omar taught “3M Solutions through High Performance Pressure Sensitive Adhesives”.
My segment of the class included hands-on experiments that demonstrated the relationships between surface energy and peel strength of pressure sensitive adhesives.
The students were incredibly engaged; as a result, the class lasted for almost 11 hours. The questions were technically very advanced and indicated a wonderful level of interest.
Bogota was a wonderful experience in itself. Founded by the Spanish Conquistadores in 1538, the old part of the city looks and feels like a medieval Spanish city. …Read More

Roosevelt University, a liberal arts college in the Loop of downtown Chicago perfectly contrasts antiquated and contemporary architecture. Roosevelt’s first venue, constructed in 1889 just in time for the World Fair, is 17 floors of beautiful Art Nouveau structure. The Auditorium Building encompasses ornate railings and scaffolding, topping off with a regal library and a lofty tower overlooking Grant Park. However, because of its age, the Auditorium Building demands constant attention and is inefficient in the frigid Chicago winters and hazy summers.
Their new building, the Wabash Building, erected in 2012 is just the opposite. Its 32 towering floors of curved glass superintends the Auditorium Building, arriving amongst the structural giants of Chicago. Illustrating the epitome of modern design, this highly efficient, state of the art structure is LEED certified.
When looking up at the two buildings, old charm vs new-age sleek, the phrase comes to mind: they just don’t make things like they used to. But, there’s necessity behind this. As the global population rises, infrastructure becomes denser, and resources become scarce, engineers concentrate on building smarter. Designing a building that spares no expense—in terms of efficiency in operation and manufacturing of these smarter materials—is pivotal. This all begins in the research and development lab and extends to the manufacturing floor. Materials and processes are developed to allow for more efficiency in both the production of materials and the final construction. Guaranteeing bonds will hold; paint, print, and coatings will stick; seals will persevere; and cleaning processes will clean effectively is crucial to manufacturing a product that will withstand stresses of any structure.
That is why more and more manufacturers are turning to the Surface Analyst™. This hand-held instrument ensures any surface is ready for effective bonding, coating, cleaning, sealing, printing, or painting. The ability to verify and quantify critical surface processes on the manufacturing floor is the keystone to efficient manufacturing and smarter structures.
A high-grade window manufacturer, for example, uses the Surface Analyst to verify plasma treatment on vinyl window frames prior to sealing. This guarantees the windows will efficiently heat or cool a structure while also withstanding the elements of rain, wind, and snow. …Read More
