An integrated laboratory experience in X-ray photoelectron spectroscopy (XPS) is designed for undergraduate and graduate students in chemistry, materials science, and other related fields. Focusing on ubiquitous Si, Cu, and their common oxides, students are guided to characterize a series of standard materials by XPS to understand the fundamentals…

Engaging in laboratory practical activities, developing laboratory practical skills, and, to a degree, even wearing laboratory protective equipment such as safety coats and goggles are all quintessential components of chemistry education. It is becoming quite common for institutions to invest in large-scale chemistry teaching laboratories, filling…

This paper outlines a comprehensive teaching laboratory course program that centers on titration analysis, a timeless and essential technique in analytical chemistry spanning various disciplines, such as environmental science, medicine, and industry. In these fields, titration analysis is paramount for determining the concentrations of substances…

The typical sound of George Lucas' laser blaster in the "Star Wars" series is well known. What does a laser blaster in "Star Wars" sound like, and why? Here we show a simple way to produce this sound by using low-cost lab material, like a spring or a Slinky. Building on the work of Crawford, who analyzed the sound of a Slinky…

One step of the published mechanism of the hydrogen peroxide iodine-clock reaction is called into question by the result of an experimental attempt (predicated on that mechanism) to integrate that reaction into the elephant's toothpaste demonstration to reveal and control its iodine side product. Under conditions that were a hybrid of those…

Assumptions about the feasibility of teaching chemistry laboratories online have been challenged by the ongoing COVID-19 pandemic. We argue that, despite the fact that pandemic social distancing restrictions will be eventually eliminated, the development of quality digital laboratory resources must continue to receive attention from the chemistry…

Research experience is becoming an increasingly crucial element of today's undergraduate science curriculum. In recent years, the establishment of the Course-Based Undergraduate Research Experience Network (CUREnet) has provided a framework for the development of courses aiming to cultivate students' proficiency in undergraduate research…

This paper describes the design, implementation, and evaluation of an inquiry-based laboratory for sophomore-level organic chemistry into a mostly cookbook, existing laboratory curriculum. For the laboratory, students were required to generate their own procedures and use their own recorded data from prior laboratory assignments to identify an…

This January marked the 52nd anniversary of the Apollo 1 fire. On Jan. 27, 1967, the interior of NASA's AS-204 command module (CM), occupied by American astronauts Roger Chaffee, Virgil "Gus" Grissom, and Ed White, caught fire during a rehearsal of its scheduled Feb. 21 launch. By the time the ground crew was able to open the hatch, the…

The rapid evolution of Artificial Intelligence (AI) is profoundly shaping our society. Among various AI tools, ChatGPT stands out for its user-friendly nature and wide accessibility to the public. However, despite their countless potential benefits, these tools also face significant challenges, especially in sensitive areas like Education. In this…

The COVID-19 pandemic crisis has modified teaching and learning throughout the world. The developments in Information Communication Technology tools have played a critical role in the education community. During the pandemic, the organization and conduction of theory classes in Universities across India were managed reasonably on one side, but the…

Among the efforts directed at remediating contaminated sites, the use of immobilized microorganisms is an appealing alternative because it offers several advantages over the use of free cells, including protecting cells from the toxic effects of hazardous compounds and increasing their survival and metabolic activity. "Pseudomonas…

A laboratory project to introduce upper-level undergraduates to Pd-catalyzed C-N [sigma]-bond forming reactions is described. The exercise involves evaluation of monodentate phosphine ligands and solvents for the Buchwald-Hartwig coupling of 4-chloro-or 4-bromo-anisole with morpholine. Students gain experience in the synthesis of a biarylphosphine…

Instrumentation plays a vital role in almost every area of chemistry. As such, it is imperative that the undergraduate curriculum is designed to allow students to have opportunities to use a variety of instruments to best prepare them for careers in chemistry. Previous work has provided evidence of the types of instruments students use in…

Equal access to an instructor's time and attention can be a barrier experienced by many underrepresented minorities. An instructor's own biases will determine the nature of their interaction with students, and even well-meaning instructors can interact with students in differential ways, which might prevent certain students from having access to…
