Although undergraduate research experience has proven to have positive effects on student outcomes, such opportunities are not always widely available. Options can be especially limited for early-career engineering students who have limited research experience. One approach to addressing this issue is to partner engineering instructors with active…

It began in 1869, and today we have 118 elements listed in the Periodic table, thanks to Mendeleev's work. Carbon, hydrogen, oxygen, and nitrogen are elements presented in many organic compounds. Some of them can exhibit photophysical and photochemical properties. Herein, we proposed an easy to make an experiment in chemistry classes to connect…

We propose an apparatus that emulates the experiment used by Geiger and Marsden in 1913 to investigate alpha particles (Rutherford) scattering. Using a widely available fused deposition modelling 3D-printer, we built a compartmented and easily assembled educational instrument. The whole apparatus is composed of a 3D-printed chamber and an…

A fluorometer is a device that measures the spectroscopic properties of fluorescent materials, and fluorometry is used widely in chemistry research settings to characterize fluorescent samples. One of the obstacles faced by undergraduate programs looking to implement fluorometer-based experiments into their laboratory curriculum is the high cost…

A Science, Technology, Engineering and Mathematics (STEM) tool is proposed in this manuscript; which consists of an interactive, simple and low-cost computer based simulation and game, with the aim of easing the teaching/learning process regarding the physics concept of projectile motion. The novelty of this proposal relies on the use of a…

A reference electrode is an essential component of all three-electrode electrochemical measurements. Common commercial reference electrodes, including the saturated calomel electrode and Ag/AgCl reference electrode, are expensive with the former containing toxic mercury. Cheaper alternatives have been proposed including Ag/AgCl references made…

Introductory chemistry students encounter the concept of hybrid orbitals as a transition from atomic orbitals to molecular bonding. The principal purpose of learning hybridization in the undergraduate curriculum is to impart an understanding of the origins of molecular bonding and geometry. Physical models of both individual hybrid orbitals and…

The 2020 pandemic involving SARS-CoV-2 (COVID-19) resulted in a rapid shift to online education for instructors at every level around the world. This shift occurred with little training and minimal resources available due to the rapidity of onset. In this technology report, we describe the use of 3D printing to rapidly manufacture mounts for…

One challenge of teaching chemical analysis is the proliferation of sophisticated, but often impenetrable, instrumentation in the modern laboratory. Complex instruments, and the software that runs them, distance students from the physical and chemical processes that generate the analytical signal. A solution to this challenge is the introduction…

The efficiency of a laundry-washing process is typically assessed using reflection measurements. A spectrometer and an integrating sphere are used to obtain the reflection data. The similarities between this equipment and a commercially available flatbed scanner are examined, and the way a flatbed scanner can be used to obtain detergent…

The system-on-chip module described here builds on a grounding in digital hardware and system architecture. It is thus appropriate for third-year undergraduate computer science and computer engineering students, for post-graduate students, and as a training opportunity for post-graduate research students. The course incorporates significant…
