A Visit to Natural Fiber Welding: Demonstrating Green Chemistry in Action

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. 

Solutions with Kristen Vanderveen

Solutions are all around us in life and chemistry class! On February 10th, 2022, Kristen Vanderveen discussed solubility curves, molarity calculations, using particulate level modeling and simulations, making real world connections and so much more in this ChemBasics Talk. View a recording of her presentation and access materials she has suggested here.

Solubility, Stoichiometry and Non-stoichiometry

The unspoken word of chemistry: Non-stoichiometric. Stoichiometry and non-stoichiometry are concepts that combine to make a solution that does not have to be difficult to understand.

Soda Fountains from Aluminum Cans

The familiar soda fountains that can be produced by adding Mentos candies to plastic bottles of carbonated beverages can also be produced by adding objects to carbonated beverages in aluminum cans. A variety of simple methods for producing soda fountains from cans are described.

Icy Brinicle of Death: A COOL Example of Freezing Point Depression

What real world examples are made known to students when discussing freezing point depression? What about brinicles, also known as "Icy Fingers of Death"? A brinicle (from brine + ice) is a finger-like formation of supercooled brine solution that grows downward underneath sea ice. Intrigued? Cool (pun intended). Keep reading to find out more!
