Alison Wallum; Zetai Liu; Joy Lee; Subhojyoti Chatterjee; Lawrence Tauzin; Christopher D. Barr; Amberle Browne; Christy F. Landes; Amy L. Nicely; Martin Gruebele – Journal of Chemical Education, 2023
As data science and instrumentation become key practices in common careers ranging from medicine to agriscience, chemistry as a core introductory course must introduce such topics to students early and at an accessible level. Advanced data acquisition and data science generally require expensive precision instrumentation and massive computation,…

Lawton, Jeffrey A.; Prescott, Noelle A.; Lawton, Ping X. – Biochemistry and Molecular Biology Education, 2018
We have developed an integrated, project-oriented curriculum for undergraduate molecular biology and biochemistry laboratory courses spanning two semesters that is organized around the "ldhA" gene from the yogurt-fermenting bacterium "Lactobacillus bulgaricus," which encodes the enzyme d-lactate dehydrogenase. The molecular…

Kousloglou, Manolis; Molohidis, Anastasios; Nikolopoulou, Kleopatra; Hatzikraniotis, Euripides – Teaching Science, 2022
The natural sciences, by their very nature, are based on the exploration of the physical world, and digital mobile devices are considered appropriate to support this exploration (Suárez et al., 2018) since they offer the tools that make this investigation more accessible but also ubiquitous (Crompton et al., 2017). Inquiry-based learning is a…

Rizvi, Waqar; Khwaja, Emaad; Siddiqui, Saim; Bhupathiraju, N. V. S. Dinesh K.; Drain, Charles Michael – Journal of Chemical Education, 2018
A physical organic chemistry experiment is described for second-year college students. Students performed nucleophilic aromatic substitution (NAS) reactions on 5,10,15,20-tetrakis(2,3,4,5,6-pentafluorophenyl)porphyrin (TPPF[subscript 20]) using three different nucleophiles. Substitution occurs preferentially at the 4-position ("para")…

Abidin, Nurul Aina Syakirah Zainal; Tho, Siew Wei – International Journal of Education and Development using Information and Communication Technology, 2018
The purpose of this research was to design and develop hands-on practical physics activity for the determination of relationship between the fundamental frequency and wavelength of standing waves using open or closed resonance tubes. In this study, an innovative use of smartphone device for the hands-on practical activity was developed with the…

Garrido-Gonza´lez, Jose´ J.; Trillo-Alcala´, María; Sa´nchez-Arroyo, Antonio J. – Journal of Chemical Education, 2018
The generation of secondary colors in digital devices by means of the additive red, green, and blue color model (RGB) can be a valuable way to introduce students to the basics of spectroscopy. This work has been focused on the spectral separation of secondary colors of light emitted by a computer screen into red, green, and blue bands, and how the…

Wei, Chin-Chuan; Jensen, Drake; Boyle, Tiffany; O'Brien, Leah C.; De Meo, Cristina; Shabestary, Nahid; Eder, Douglas J. – Journal of Chemical Education, 2015
To provide a research-like experience to upper-division undergraduate students in a biochemistry teaching laboratory, isothermal titration calorimetry (ITC) is employed to determine the binding constants of lysozyme and its inhibitors, N-acetyl glucosamine trimer (NAG[subscript 3]) and monomer (NAG). The extremely weak binding of lysozyme/NAG is…

George, Danielle J.; Hammer, Nathan I. – Journal of Chemical Education, 2015
This undergraduate physical chemistry laboratory exercise introduces students to the study of probability distributions both experimentally and using computer simulations. Students perform the classic coin toss experiment individually and then pool all of their data together to study the effect of experimental sample size on the binomial…

Tabassum, Tahseen; Iloska, Marija; Scuereb, Daniel; Taira, Noriko; Jin, Chongguang; Zaitsev, Vladimir; Afshar, Fara; Kim, Taejin – Journal of Chemical Education, 2018
3D printing technology has an enormous potential to apply to chemical engineering education. In this paper, we describe several designs of 3D printed mesoreactors (Y-shape, T-shape, and Long channel shape) using the following steps: reactor sketching, CAD modeling, and reactor printing. With a focus on continuous plug flow mesoreactors (PFRs, i.d.…

Brunauer, Linda S. – Journal of Chemical Education, 2016
A multiweek protein purification suite, suitable for upper-division biochemistry or biotechnology undergraduate students, is described. Students work in small teams to isolate the enzyme lactate dehydrogenase (LDH) from a nontraditional tissue source, mammalian blood, using a sequence of three column chromatographic procedures: ion-exchange, size…

Black, Andy Nicholas; Magruder, Robert H. – Physics Teacher, 2017
Learning and understanding physics requires more than studying physics texts. It requires doing physics. Doing research is a key opportunity for students to connect physical principles with their everyday experience. A powerful way to introduce students to research and technique is through subjects in which they might find interest. Presented is…

Galeriu, Calin; Edwards, Scott; Esper, Geoffrey – Physics Teacher, 2014
We cannot hope for a new generation of scientists and engineers if we don't let our young students take ownership of their scientific and engineering explorations, if we don't let them enjoy the hands-on cycle of design and production, and if we don't let them implant their creativity into a technologically friendly environment.…

Dean, J.; Allwood, D. A. – Physics Education, 2014
We describe a range of practical activities that allows students to investigate the properties and applications of magnets. The activities can be used in isolation or used together to build a rounded understanding of the subject area. The activities include simple demonstrations using common or inexpensive equipment, hands-on experiments for small…

Mendez, Sergio; AungYong, Lisa – Chemical Engineering Education, 2014
To help students make the connection between the concepts of heat conduction and convection to real-world phenomenon, we developed a combined experimental and computational module that can be incorporated into lecture or lab courses. The experimental system we present requires materials and apparatus that are readily accessible, and the procedure…

Campbell, Dean J.; Peterson, Joshua P.; Fitzjarrald, Tamara J. – Journal of Chemical Education, 2013
These laboratory experiments are designed to familiarize students with concepts of spectroscopy by using sound waves. Topics covered in these experiments include the structure of nitinol alloys and polymer chain stiffness as a function of structure and temperature. Generally, substances that are stiffer or have higher symmetry at the molecular…
