Delgado, Teresa; Villard, Me´lanie – Journal of Chemical Education, 2022
Spin crossover (SCO) materials that switch between two different spin states, that is, the high spin (HS) and the low spin (LS) state, with very different optical, magnetic, and structural properties offer a unique platform to understand the consequences induced by the different electronic configurations of transition metal complexes. Due to the…

Hal Van Ryswyk; Hanna Z. Porter; Connor K. M. Seto; Ixchel Lopez; Emma Dy – Journal of Chemical Education, 2023
Pulsed field gradient nuclear magnetic resonance (NMR) is used to estimate the size of quantum dots (QDs) produced in a simple, fast, small-scale synthesis. This upper-division laboratory experiment teaches the basics of QD synthesis and pulsed field gradient NMR, a powerful technique for measuring diffusion coefficients in solution. The diffusion…

Billingsley, Brianna R.; Christenson, Cory W. – Physics Teacher, 2022
A popular introductory physics laboratory experiment is one focusing on Snell's law. This is straightforward to complete with lasers and prisms, but here we present an alternative version that guides the students through some of the major historical developments, recreating and analyzing significant experiments. The discovery of Snell's law has a…

Busovský, Damián; Krízová, Michaela; Kríz, Jan; Loskot, Jan; Studnicka, Filip; Slégrová, Leontýna; Slégr, Jan – Physics Education, 2022
Undergraduate physics laboratory exercises are very important in shaping students' attitude to science, especially for future teachers. Recently, it is necessary to look for ways to easily create large quantities of experimental sets, not only for institutional use, but also for sets that can be produced in large quantities and distributed for use…

Sharifov, Galib Movsum oghlu – Physics Education, 2020
This article deals with an exploration of a double superior mirage obtained in laboratory conditions and its contribution to the deep understanding of light events in specialized schools. It was revealed that an explanation of the formation process of a double superior mirage plays a key role in the adoption of knowledge on reflection and…

Vasicek, Thaddeus W.; Kress, Patrick M.; Jenkins, Samir V. – Journal of Chemical Education, 2020
Nanoscale phenomena are under increasingly intense investigation both in academia and industry. The unique physical and chemical properties stemming from their high surface area and confined space lead to properties that are distinct from atomic and bulk materials. Students need experience in nanoscience to enter this growing field of nanoscience…

Bracker, Rachel; Dominguez, Kimberly; Stender, Anthony S. – Journal of Chemical Education, 2020
Nanoparticles are an increasingly important tool in chemistry research, but currently there are few opportunities for chemistry students to work with nanoparticles in undergraduate analytical courses. In this exercise, designed for an analytical or instrumental analysis lab course, students have the opportunity to work with solutions of silver…

Haverkamp, Nils; Pusch, Alexander; Heusler, Stefan; Gregor, Markus – Physics Education, 2022
Quantum technology is an emerging field of physics and engineering and important applications are expected in quantum computing, quantum sensing, quantum cryptography, quantum simulation, and quantum metrology. Thus the need for education in this field is increasing, while still remaining challenging. While the need for basic education in quantum…

Khoa, Dinh Xuan; Bang, Nguyen Huy – Physics Teacher, 2019
We constructed a low-cost experimental kit consisting of a compact 532-nm diode laser, optics, and optomechanical components that arrange on a small honeycomb breadboard. The kit is flexible enough to construct five typical wave optic experiments, e.g., double-slit interference, Michelson and Mach-Zehnder interferometers, diffraction, and Malus's…

Amirjani, Amirmostafa; Koochak, Niloofar Namazi; Haghshenas, Davoud Fatmehsari – Journal of Chemical Education, 2019
In the laboratory experiment described here, students synthesize silver nanostructures (AgNS) with different shapes and sizes to elucidate the shape- and size-dependent optical properties of nanostructured materials. Students also develop understanding of some thermodynamic and kinetic aspects of the synthesis process through this experiment. In…

The pandemic triggered by the SARS-CoV-2 virus has produced worldwide interruptions of face-to-face teaching activity in both schools and universities. In Italy, the quarantine began in the second half of February 2020 and lasted for all the second semester of lectures. The University of Bologna, where all the authors of the present article are…

Dark, Marta L. – Physics Education, 2021
In fall 2020, the Physics Department was tasked with coming up for a plan for optics, our one credit lab course. Because of the continued COVID-19 pandemic, our institution planned to offer a fully online fall semester, with no students residing on campus. The college announced the plan 5 weeks prior to the start of the semester. This paper will…

Rosi, Tommaso; Gratton, Luigi M.; Onorato, Pasquale; Oss, Stefano – Physics Education, 2019
We propose to reconsider the well-known experiment about the interference of white light from a thin soap film by adopting as an illuminating source the RGB triad produced by a LED projector. The interference pattern shows up in a particularly fascinating way and it contains direct, essential information about both the wave nature of light and of…

Singh, I.; Khun Khun, K.; Kaur, B. – Physics Education, 2018
Excel spreadsheets are used as an excellent tool in physics laboratory experiments related to wave optics. This paper presents a simple way to simulate diffraction of waves through a slit using Excel spreadsheets without any tedious programming. These simulations are used to visualize the effect of variation of different parameters such as number…

Chen, Huai-Yi; Wu, Chien-Ming; Lai, Chiung-Hui – IEEE Transactions on Education, 2019
Contribution: Prior studies indicate that students experimenting with characterization of optical planar waveguides use expensive ready-made prism couplers without clear understanding about construction of the entire optical measurement system. This paper presents a cost-effective modified bright-mode prism coupler that helps students learn…
