  • A Second Look at the Kinetics of the Iron−Oxygen Reaction: Determination of the Total Order Using a Greener Approach

    A. M. R. P. Bopegedera (The Evergreen State College, Washington);
    J. Chem. Educ., 95, 2018, pp 1897−1899.

    The author demonstrates how to use Vernier Oxygen Gas Sensors and Logger Pro software to monitor the change in oxygen level as the iron in commercial hand warmers react with the air above them.

  • Investigating NOx Concentrations on an Urban University Campus Using Passive Air Samplers and UV−Vis Spectroscopy

    Cole M. Crosby, Richard A. Maldonado, Ahyun Hong, Ryan L. Caylor, Kristine L. Kuhn, and Matthew E. Wise (Concordia University, Oregon);
    J. Chem. Educ., 95, 2018, pp 2023−2027.

    The authors demonstrate how to use Vernier SpectroVis Plus Spectrophotometers and LabQuest 2 interfaces to measure gaseous nitrogen oxides concentrations.

  • Investigating the Clough, Lutz, and Jirgensons Rule for the pH Dependence of Optical Rotation of Amino Acids

    Scott Simpson and Alexandra M. Izydorczak (St. Bonaventure University, New York);
    J. Chem. Educ., 95, 2018, pp 1872−1874.

    Students use a Vernier Chemical Polarimeter and Logger Pro software to determine if lowering the pH on L configuration amino acids causes the molar optical rotation to become more positive.

  • Buffers in Context: Baby Wipes As a Buffer System

    Jon-Marc G. Rodriguez, Sarah Hensiek, Jeanne R. Meyer, Cynthia J. Harwood, and Marcy H. Towns (Purdue University, Indiana);
    J. Chem. Educ., 95, 2018, pp 1816−1820.

    Students use baby wipes and deionized water to create and test buffer solutions. Vernier pH Sensors and LabQuest 2 interfaces help students study the buffer solutions.

  • Unnatural Chemical Biology: Research-Based Laboratory Course Utilizing Genetic Code Expansion

    Kelsey M. Kean, Kari van Zee, and Ryan A. Mehl (Oregon State University, Oregon);
    J. Chem. Educ., 96, 2019, pp 66−74.

    Students use a Vernier SpectroVis Plus Spectrophotometer or Gas Pressure Sensor to determine the kinetics of enzyme hydrolysis.

  • Combining the Maker Movement with Accessibility Needs in an Undergraduate Laboratory: A Cost-Effective Text-to-Speech Multipurpose, Universal Chemistry Sensor Hub (MUCSH) for Students with Disabilities

    Ronald Soong, Kyle Agmata, Tina Doyle, Amy Jenne, Tony Adamo, and Andre Simpson (University of Toronto, Ontario);
    J. Chem. Educ., 95, 2018, pp 2268−2272.

    The researchers develop a cost-effective sensor interface that uses Arduino technology. This article describes how to use a Vernier pH BNC electrode and open source software.

  • Demonstration Extensions Based on Color-Changing Goldenrod Paper

    Donald K. Schorr and Dean J. Campbell (Bradley University, Illinois);
    J. Chem. Educ., [Online early access], DOI: 10.1021/acs.jchemed.8b00341, Published Online: Dec 5, 2018, https://pubs.acs.org/doi/10.1021/acs.jchemed.8b00341 (accessed Feb 8, 2019).

    The authors use a Vernier UV-VIS Spectrophotometer to examine ultraviolet and visible absorbance spectra from extracts of goldenrod paper.

  • Modified Siwoloboff−Wiegand Procedure for the Determination of Boiling Points on a Microscale

    Timothy L. Troyer, Kristen R. Mounsey, William J. King, Laura M. Givens, Jessica A. Hutton, Melissa Hood Benges, Kindra N. Whitlatch, and Jacob D. Wagoner (Huntington University, Indiana; West Virginia Wesleyan College, West Virginia);
    J. Chem. Educ., 95, 2018, pp 1406−1410.

    The authors devise a system to determine the boiling points of very small volumes of liquids using a digital hotplate, block of aluminum, Go!Temp temperature probe, and an original LabQuest interface.

  • Applying Chemistry Knowledge to Code, Construct, and Demonstrate an Arduino−Carbon Dioxide Fountain

    Seong-Joo Kang, Hye-Won Yeo, and Jihyun Yoon (Korea National University of Education, Republic of Korea, Dankook University, Republic of Korea);
    J. Chem. Educ., [Online early access], DOI: 10.1021/acs/jchemed.8b00663, Published Online: Jan 30, 2019, https://pubs.acs.org/doi/10.1021/acs.jchemed.8b00663 (accessed Feb 8, 2019).

    The authors automate a classic experiment, the Carbon Dioxide Fountain, by using a Vernier Gas Pressure Sensor connected to an Arduino microcontroller.
