Dean Campbell uses demonstrations and props to illustrate concepts while teaching his collegiate Materials Chemistry course. Many of the examples described are also suitable for use in high school and collegiate General Chemistry courses.
The theme to the 2022 National Chemistry Week, observed October 16-22, is “Fabulous Fibers: The Chemistry of Fabrics”. A visit to Natural Fiber Welding, Inc. in Peoria, IL, revealed how that company is using ionic liquids to solvent weld cellulose fibers together to produce more durable yarn which can then be made into more durable fabric. The production method and “greenness” of the product is discussed, from the cellulose itself to the recycling of the solution used in the welding process. Macroscopic demonstrations of the fiber solvent welding process are also described.
Some explorations and explanations regarding superconductors and the quantum levitation (also known as quantum locking) experiment.
The June, 2018 issue of the Journal of Chemical Education contains an article that describes a simple, yet fascinating experiment that you and your students are going to love! It involves the use of butterfly wings from the genus Morpho.
Read Dr. Nakita Noel’s career profile describing her background and her current position as a Postdoctoral Research Fellow at the Princeton Research Institute for the Science and Technology of Materials.
Erica Jacobsen shares highlights from the January 2019 issue of the Journal of Chemical Education.
I’ve always been fascinated by advanced polymeric materials; it’s amazing how materials that are generally considered “plastics” have such stunning properties. I recently watched a couple of movies about Batman and it came out that some of his devices and protections are made of advanced polymers. In particular, the suit is almost entirely made of Kevlar.
The science behind the incredibly popular Scrub Daddy sponge is investigated. Part of the appeal of the Scrub Daddy sponge is that it changes from soft to hard depending upon temperature. This allows a single sponge to be transformed into a hard scrubber or soft sponge, depending upon the temperature of water into which it is placed.
Years ago, I took some wonderful material science workshops sponsored by ASM International. They did an amazing job of helping me add some more tools to my teaching tool kit. Materials are all around us and the workshop was a week long adventure into either creating a material science course or tying material science into existing curriculum. The chemistry of materials can easily be introduced into any curriculum.
The June 2015 issue of the Journal of Chemical Education is now available online to subscribers at http://pubs.acs.org/toc/jceda8/92/6. This issue includes articles on curriculum; assessment; inorganic chemistry; investigating galvanic cells & exploring LEDs; atomic structure; nanochemistry laboratories; physical chemistry in the lab; synthesis.
