Rasa, Tapio; Palmgren, Elina; Laherto, Antti – Instructional Science: An International Journal of the Learning Sciences, 2022
To promote students' value-based agency, responsible science and sustainability, science education must address how students think about their personal and collective futures. However, research has shown that young people find it difficult to fully relate to the future and its possibilities, and few studies have focused on the potential of science…

Lisensky, George; McFarland-Porter, Ross; Paquin, Weltha; Liu, Kangying – Journal of Chemical Education, 2020
Nanoparticle Zn[subscript 2x] Cu[subscript 1-x] In[subscript 1-x] S[subscript 2] is a promising and safer alternative to lead- and cadmium-containing quantum dots. Students prepare Zn[subscript 0.44] Cu[subscript 0.78] In[subscript 0.78] S[subscript 2] quantum dots in a one-pot synthesis without an inert atmosphere and investigate how the color,…

Roupioz, Yoann – Journal of Chemical Education, 2019
A simple bioassay was designed for the detection of adenosine, a human metabolite involved in several physiological processes, on the basis of the functionalization of gold nanoparticles with DNA oligonucleotides selectively binding adenosine. The test was possible thanks to the selective and sensitive binding of adenosine by two DNA…

Parker, Andrew K.; Danielson, Emily T.; Black, Shaun D. – Journal of Chemical Education, 2021
Nanochemistry is an important aspect of modern chemical science. Though few educational institutions teach nanochemistry as a formal course, general exposure of students to nanoscience is yet important. Thus, we present a nanochemical activity that could be used as part of many chemistry courses or laboratories based on ChemToy2. This activity is…

Fisher, Adam J.; Keeley, Monica M.; Lane, Jeremy M.; Furlan, Ping Y. – Journal of Chemical Education, 2019
We describe a 2 h general-chemistry experiment that introduces college students not only to the concepts, synthesis, and applications of nanomaterials at an early stage but also the use of a spectrophotometer for quantification and unknown determination based on Beer's Law. The procedure involves students (1) preparing a nanocomposite by…

Vahedi, Amid; Farnoud, Amir M. – Journal of Chemical Education, 2019
The increasing industrial and biomedical applications of nanomaterials have enhanced the need to educate a well-trained nanotechnology workforce. This need has led to efforts to introduce hands-on, nanotechnology-based, experimental modules into high school and college level courses in science and engineering. However, the majority of such efforts…
