Noei, Nima; Imani, Iman Mohammadi; Wilson, Lee D.; Azizian, Saeid – Journal of Chemical Education, 2019
A low-cost and simple setup to measure the densities of liquids is introduced herein. The results and reliability of this setup were evaluated for pure liquids, water-ethanol binary mixtures, and aqueous NaCl solutions. The constructed densitometer provided density values with acceptable relative errors (less than ±3.0%), which were compared to…

Fedick, Patrick W.; Schrader, Robert L.; Ayrton, Stephen T.; Pulliam, Christopher J.; Cooks, R. Graham – Journal of Chemical Education, 2019
Process analytical technologies (PATs) are used in the pharmaceutical and other industries to monitor chemical processes in real-time with analytical instrumentation. Each PAT analyzer brings its own advantages and disadvantages to the process, and multiplexing PAT analyzers can be advantageous as they can provide confirmatory measurements and…

Kwan, Ann H.; Mobli, Mehdi; Schirra, Horst J.; Wilson, Jennifer C.; Jones, Oliver A. H. – Journal of Chemical Education, 2019
Magnetic resonance is a powerful technology that has had a major impact across the physical, life, and medical sciences, from chemistry to medical imaging, with ever-expanding applications in new areas as diverse as mining and food science. It is, however, also a difficult subject to teach, as the theory is complex and requires some familiarity…

Padilla Mercado, Jeralyne B.; Coombs, Eri M.; De Jesus, Jenny P.; Bretz, Stacey Lowery; Danielson, Neil D. – Journal of Chemical Education, 2018
Multifunctional chemical analysis (MCA) systems provide a viable alternative for large scale instruction while supporting a hands-on approach to more advanced instrumentation. These systems are robust and typically use student stations connected to a remote central computer for data collection, minimizing the need for computers at every student…

Davis, Eric J.; Jones, Michael; Thiel, D. Alex; Pauls, Steve – Journal of Chemical Education, 2018
Additive manufacturing (3D printing) is a technology with near-unlimited potential for the chemical educator. However, its adoption into higher education has been limited by the dual requirements of expertise in 3D printing and 3D computer-aided design (CAD). Thus, its reported utilization in the chemistry curriculum has been within the creation…

Ritchie, Tessy S.; Cardenas, Maria T. Perez; Ganapati, Shweta – Journal of Chemical Education, 2018
Professional development in chemistry doctoral programs has traditionally relied on the skills and opportunities embedded within the requirements of the Ph.D. program being sufficient for employment. As a result, little emphasis is usually placed on career planning and exploration within the doctoral curriculum. Additionally, the support provided…

Al-Moameri, Harith H.; Jaf, Luay A.; Suppes, Galen J. – Journal of Chemical Education, 2018
Traditional engineering textbooks are substantially limited by approaches relying on analytical solutions where most of the applications are described by differential equations without simple analytical solutions. An alternative is to design a textbook around computer-program-based simulations, where the simulations progressively evolve through…

Bellová, Renata; Melichercíková, Danica; Tomcík, Peter – Journal of Chemical Education, 2018
This paper describes the implementation of problem-based learning in chemical education with regard to the impact that protolytic reactions have on equilibria. The problem-based task presented here is focused on extremely weak acids and calcuation of the pH value of their aqueous solutions. The task is based on comparisons of K[subscript a] ranges…

Bonjour, Jessica L.; Hass, Alisa L.; Pollock, David W.; Huebner, Aaron; Frost, John A. – Journal of Chemical Education, 2017
Development of benchtop, portable Fourier transform nuclear magnetic resonance (NMR) and infrared (IR) spectrometers has opened up opportunities for creating university-high school partnerships that provide high school students with hands-on experience with NMR and IR instruments. With recent changes to the international baccalaureate chemistry…

Sabanayagam, Kalyani; Dani, Vivek D.; John, Matthew; Restivo, Wanda; Mikhaylichenko, Svetlana; Dalili, Shadi – Journal of Chemical Education, 2017
This paper describes the successful adaptation of certain components of peer-led team learning (PLTL) as well as service learning principles into our initiative: lab skills seminars (LSS). These seminars were organized for large, second year organic chemistry laboratory courses. Prior to LSS, the only help available for students was traditional…

Beussman, Douglas J.; Walters, John P. – Journal of Chemical Education, 2017
Virtually all modern chemical instrumentation is controlled by computers. While software packages are continually becoming easier to use, allowing for more researchers to utilize more complex instruments, conveying some level of understanding as to how computers and instruments communicate is still an important part of the undergraduate…

Murov, Steven; Chavez, Arnold – Journal of Chemical Education, 2017
Despite its vital importance in our lives, chemistry is inadequately represented in most museums. Issues such as safety, replenishing and disposal of chemicals, supervision required, and cost are constraints that have limited the number and size of chemistry exhibits. Taking into account the constraints, a 21-station interactive and inexpensive…

Carraher, Charles E., Jr.; Berda, Erik; Blum, Frank D.; Droske, John P.; Ford, Warren T.; Howell, Bob A.; Long, John M.; Morgan, Sarah E. – Journal of Chemical Education, 2017
The Committee on Polymer Education (PolyEd) had its initial planning meeting in 1974. The Intersociety Polymer Education Council (IPEC) has been active since 1990 as an outgrowth of PolyEd. Because of the activities of PolyEd and IPEC, basic polymer concepts have become a required part of undergraduate education and a more common topic in the…

Howell, Bob A. – Journal of Chemical Education, 2017
The impact of polymeric materials on the well-being of citizens of the modern world is enormous. These materials enhance virtually every facet of life--from clothing and personal care items to housing and transportation. Yet despite this, and the fact that most chemists work in a polymer or polymer-related area, polymeric materials have…
