Sanders, Wesley C.; Valcarce, Ron; Iles, Peter; Smith, James S.; Glass, Gabe; Gomez, Jesus; Johnson, Glen; Johnston, Dan; Morham, Maclaine; Befus, Elliot; Oz, Aimee; Tomaraei, Mohammad – Journal of Chemical Education, 2017
This manuscript describes a laboratory experiment that provides students with an opportunity to create conductive silver nanogrids using polymeric templates. A microcontact-printed polyvinylpyrrolidone grid directs the citrate-induced reduction of silver ions for the fabrication of silver nanogrids on glass substrates. In addition to…

Kondratowicz, Izabela; Z?elechowska, Kamila – Journal of Chemical Education, 2017
The aim of this laboratory experiment is to utilize graphene oxide (GO) material to introduce undergraduate students to many well-known concepts of general chemistry. GO is a new nanomaterial that has generated worldwide interest and can be easily produced in every well-equipped undergraduate chemical laboratory. An in-depth examination of GO…

Longenberger, Taylor B.; Ryan, Kaleigh M.; Bender, William Y.; Krumpfer, Anna-Katharina; Krumpfer, Joseph W. – Journal of Chemical Education, 2017
Siloxane polymers and silicone materials are major components in most people's daily lives and are important in a wide variety of applications. However, despite their undeniable importance, they are often overlooked in the traditional undergraduate education, as they do not fall neatly into the traditional categories of organic or inorganic…

Utgikar, Vivek P.; MacPherson, David – Journal of Chemical Education, 2016
Students in the undergraduate "transport phenomena" courses typically have a greater difficulty in understanding the theoretical concepts underlying the mass transport phenomena as compared to the concepts of momentum and energy transport. An experiment based on dissolution of carbon dioxide in water was added to the course syllabus to…

Paton-Walsh, Clare – Journal of University Teaching and Learning Practice, 2015
This paper describes a study aimed at assessing the ability of report templates to help students learn key concepts during undergraduate laboratory classes. The report templates were designed so that a set of assessment questions led the students through the logical steps required to perform the laboratory exercise and to calculate the required…

Pantaleao, Ines; Portugal, Ana F.; Mendes, Adelio; Gabriel, Joaquim – Journal of Chemical Education, 2010
A pedagogical experiment is described to examine the physical absorption of gases, in this case carbon dioxide, in a hollow fiber membrane contactor (HFMC) where the absorption concentration profile can be followed by a color change. The HFMC is used to teach important concepts and can be used in interesting applications for students, such as…

Clausen, Donald F. – Improving College and University Teaching, 1980
The application of principles learned in a first course in chemistry to chemical problems of interest to home economics majors specializing in clothing and textiles or fashion merchandising is described. Concept transfer--teaching difficult concepts in terms of an everyday analogue--is also explained and relevant laboratory experiments are…
