Timmer, Brien J. J.; Schaufelberger, Frederik; Hammarberg, Daniel; Franzén, Johan; Ramström, Olof; Dinér, Peter – Journal of Chemical Education, 2018
Green chemistry and sustainable development have become increasingly important topics for the education of future chemists. The cross-disciplinary nature of green chemistry and sustainable development often means these subjects are taught in conjunction with other subjects, such as organic chemistry and chemical engineering. Herein, a…

Cooper, Tyler; Trafford, Russell; Attaluri, Anilchandra; Vernengo, Andrea Jennifer – Chemical Engineering Education, 2018
This paper describes an undergraduate laboratory experiment where students study the heating behavior of magnetic nanoparticles in the presence of alternating magnetic fields. Average score on the post-test was 45±12% for students who completed the lab online, versus 43±11% for those doing the activity hands-on. Post-test scores were significantly…

Ramalho, Maria J.; Pereira, M. Carmo – Journal of Chemical Education, 2016
In this work, a laboratory experiment to introduce graduate students to nanotechnology is described. Students prepared poly(lactic-"co"-glycolic acid) (PLGA) nanoparticles using two different synthesis procedures, a single and a double emulsion-solvent evaporation method. The students also performed a physicochemical characterization of…

Taipa, M. A^ngela; Azevedo, Ana M.; Grilo, Anto´nio L.; Couto, Pedro T.; Ferreira, Filipe A. G.; Fortuna, Ana R. M.; Pinto, Ine^s F.; Santos, Rafael M.; Santos, Susana B. – Journal of Chemical Education, 2015
An integrative laboratory study addressing fundamentals of enzyme catalysis and their application to reactors operation and modeling is presented. Invertase, a ß-fructofuranosidase that catalyses the hydrolysis of sucrose, is used as the model enzyme at optimal conditions (pH 4.5 and 45 °C). The experimental work involves 3 h of laboratory time…

Trujilo-de Santiago, Grissel; Rojas-de Gante, Cecillia; García-Lara, Silverio; Ballesca´-Estrada, Adriana; Alvarez, Marion Moise´s – Journal of Chemical Education, 2014
A simple experiment designed to study mixing of a material of complex rheology in a stirred tank is described. Non-Newtonian suspensions of blue maize flour that naturally contain anthocyanins have been chosen as a model fluid. These anthocyanins act as a native, wide spectrum pH indicator exhibiting greenish colors in alkaline environments, blue…
