Yufei Wang; Rebecca J. Abergel – Journal of Chemical Education, 2023
In view of the mounting requirements for courses in nuclear chemistry and radiochemistry, hands-on experience in the separations of radioisotopes is imperative. Three separation techniques commonly used were introduced, coprecipitation, liquid-liquid extraction, and ion-exchange chromatography. Their principles and the associated fundamental…

Huanyu Ren; Jiajun Zhang; Liqi Peng; Huihui Li; Zhi Su – Journal of Chemical Education, 2023
This work presents a homemade multirole 3D-printed modular spectrometer(MPMS), which can be easily assembled like bricks and expanded with several modules to measure different types of spectra, such as UV-vis absorption, fluorescence emission, flame emission/absorption, glow discharge, and even Raman spectra. The spectrometer is designed to be…

Dagdeviren, Omur E. – Physics Education, 2018
Propagation of sound waves is one of the fundamental concepts in physics. Some of the properties of sound propagation such as attenuation of sound intensity with increasing distance are familiar to everybody from the experiences of daily life. However, the frequency dependence of sound propagation and the effect of acoustics in confined…

Marchut, Amber E.; Gormally, Cara L. – Journal of the Scholarship of Teaching and Learning, 2019
Active learning pedagogies such as inquiry-based learning have the potential not only to improve students' science literacy but also promote affective learning and interest in science, technology, engineering, and mathematics (STEM) careers. Moreover, a focus on affective learning may be key to improve recruitment in STEM. Yet, we know little…
