Delgado-González, M. J.; Carmona-Jiménez, Y.; Rodríguez-Dodero, M. C.; García-Moreno, M. V. – Journal of Chemical Education, 2018
Colorimetry allows every color to be defined as a combination of three values, known as "color coordinates." Color coordinates allow researchers to universalize and standardize their color measurements, and nowadays, determining the color coordinates of samples is a routine method applied by organic and analytical chemists, students, and…

Cervellati, Rinaldo; Greco, Emanuela – Journal of Chemical Education, 2017
Oscillating chemical reactions in the homogeneous phase have been studied intensively only since the mid-1960s, but they were known since 1920, having as forerunners the chemist William C. Bray and an "atypical" chemist Alfred J. Lotka. This contribution is the result of a careful reading of their literature and patient research into…

Undergraduate research experiences can improve student success in graduate education and STEM careers. During the COVID-19 pandemic, undergraduate researchers at our institution and many others lost their work-study research positions due to interruption of in-person research activities. This imposed a financial burden on the students and…
