Green fluorescent protein has long been a favorite protein for demonstrating protein purification in the biochemistry lab course. The protein's vivid green color helps demonstrate to students the concept(s) behind affinity or ion exchange chromatography. We designed a series of introduction to biochemistry labs utilizing a thermostable green…

A major challenge when designing new experiments for the general chemistry laboratory is introducing students to the necessary techniques while keeping the experiment engaging and accessible. This work presents a new multiweek activity designed to introduce students to advanced instrumentation in the form of high-performance liquid chromatography…

A chemistry laboratory experiment is described to introduce undergraduate college students to membrane separation technology. This experiment combines a simple nanowire membrane fabrication and visually indicated molecule separation. The membrane is produced via coprecipitation synthesis followed by a filtration assembly process, which can be…

Lakes are artists' pigments made from colorants bound to an inert substrate, usually hydrated aluminum oxide. Before the late 19th century, lakes were made from natural pigments extracted from plants and insects, extracted either directly from the dyestuff or indirectly from waste materials generated in the manufacture of dyed textiles. The first…

The interdisciplinary nature, breadth of topics and frequently evolving industries Family and Consumer Sciences (FCS) courses engage with make it difficult for one approach to be appropriate in all circumstances. The Advanced Textiles, 4000 level course participating in this study focused mainly on color science, dyes and dyeing, in addition to…
