Bogucki, Ryan; Greggila, Mary; Mallory, Paul; Feng, Jiansheng; Siman, Kelly; Khakipoor, Banafsheh; King, Hunter; Smith, Adam W. – Journal of Chemical Education, 2019
Low cost, open-source analytical instrumentation has the potential to increase educational outcomes for students and enable large-scale citizen science projects. Many of these instruments rely on smartphones to collect the data, mainly because they can effectively leverage a dramatic price-to-performance ratio of the optical sensors. However,…

Di Vincenzo, Antonella; Floriano, Michele A. – Journal of Chemical Education, 2019
An application for visualizing the aggregation of structureless atoms is presented. The application allows us to demonstrate on a qualitative basis, as well as by quantitatively monitoring the aggregate surface/volume ratio, that the enhanced reactivity of nanoparticles can be connected with their large specific surface. It is suggested that,…

Yin, Dezhong; Chen, Jinhua; Gu, Bin; Geng, Wangchang – Journal of Chemical Education, 2018
A new experiment based on phase inversion of Pickering emulsions was carried out in a physical chemistry course. The emulsions were stabilized by surfactant-modified SiO[subscript 2] particles. As the concentration of surfactant increased, the emulsions changed from oil-in-water type (O/W) to water-in-oil type (W/O) type, and then reverted to be…

Mercier, Philippe H. – Journal of Chemical Education, 2018
Le Châtelier's principle is used as a basis to derive an expression to calculate solution pH during titrations that involve only strong acids and strong bases. Central to this model are the reaction quotient and a re-equilibration term that represents the extent of neutralization during a titration. Unlike the method traditionally taught to…

Heider, Emily C.; Valenti, Domenic; Long, Ruth L.; Garbou, Amel; Rex, Matthew; Harper, James K. – Journal of Chemical Education, 2018
Service-learning (SL) is an active learning approach that connects the knowledge a student acquires in the classroom to an application that benefits the community. Increasingly popular in the chemistry curriculum, service-learning is reported to provide student benefits including improved cognitive goals; increased academic, interpersonal, and…

Smith, Andri L.; Paddock, Jean R.; Vaughan, Joel M.; Parkin, David W. – Journal of Chemical Education, 2018
The challenge in chemistry courses for nonscience majors (such as nursing majors) is not that the students cannot learn chemistry but that they "think" they cannot learn chemistry. With this in mind, the authors' goal was to create a learning environment in which students would feel motivated to learn and would gain confidence in their…

Messerle, Louis – Journal of Chemical Education, 2018
iSchlenk, a portable instructional cart with equipment for hands-on student experience in safe handling of air-sensitive, moisture-sensitive, toxic, pyrophoric, and/or radioactive chemical materials, is described. The cart, for use by =4 students, has compressed air and vacuum from a diaphragm vacuum pump supplied to 4 three-port Schlenk lines…

Harakas, George N. – Journal of Chemical Education, 2018
This work describes an effective, low cost method to anodize small aluminum objects. The use of a PVC spacer between the anode and cathode significantly reduces the size of the electrochemical cell and electrolyte required for its operation. Students will explore the physical and chemical properties of aluminum and anodized aluminum. They will…

Newman, Karla – Journal of Chemical Education, 2018
Almost all commercial quadrupole ICP-MS instruments use collision/reaction cells to either attenuate spectral interferences or shift the analyte of interest to an interference-free "m/z" (e.g., by O addition). A laboratory practical was developed to introduce the students to the basic operating principles of ICP-MS using a hands-on…

Sweet, Chelsea; Akinfenwa, Oyewumi; Foley, Jonathan J., IV – Journal of Chemical Education, 2018
We present an interactive discovery-based approach to studying the properties of real gases using simple, yet realistic, molecular dynamics software. Use of this approach opens up a variety of opportunities for students to interact with the behaviors and underlying theories of real gases. Students can visualize gas behavior under a variety of…

Truong, Thai Phat; Bailey, Sophia J.; Golliher, Alexandra E.; Monroy, Erika Y.; Shrestha, Uttar K.; Maio, William A. – Journal of Chemical Education, 2018
The ability of certain organometallic reagents to react via 1,2- or 1,4-addition to an a,ß-unsaturated ketone is a fundamental example of regioselectivity at the second-year undergraduate organic level. The following two experiments were designed to demonstrate this preference by exploiting carvone as an inexpensive chiral, nonracemic substrate.…

Hoben, John P.; Wang, Jianing; Miller, Anne-Frances – Journal of Chemical Education, 2017
A signature of life is that biological molecules occur as a single stereoisomer with respect to each chiral center, and this is echoed in the structures of biological polymers. Thus, circular dichroism (CD) has emerged as a hallmark of biomolecular structures. The tangible and familiar phenomenon of raw egg white's conversion from transparent…

Johnstone, Erik V.; Yates, Mary Anne; Poineau, Frederic; Sattelberger, Alfred P.; Czerwinski, Kenneth R. – Journal of Chemical Education, 2017
The radioactive nature of technetium is discussed using a combination of introductory nuclear physics concepts and empirical trends observed in the chart of the nuclides and the periodic table of the elements. Trends such as the enhanced stability of nucleon pairs, magic numbers, and Mattauch's rule are described. The concepts of nuclear binding…

Lu, Yang; Santino, Luciano M.; Acharya, Shinjita; Anandarajah, Hari; D'Arcy, Julio M. – Journal of Chemical Education, 2017
The design and fabrication of functional scientific instrumentation allows students to forge a link between commonly reported numbers and physical material properties. Here, a two-point and four-point probe station for measuring electrical properties of solid materials is fabricated via 3D printing utilizing an inexpensive benchtop…

Barcena, Homar; Maziarz, Katarzyna – Journal of Chemical Education, 2017
In an effort to repurpose expired guaifenesin tablets, experiments devised for practical instruction are reported for the preparation and isolation of the guaifenesin acetonide using a microscale kit. The laboratory experiment successfully utilizes a waste chemical in lieu of a fine chemical to illustrate the principles behind protecting groups in…
