As an alternative to the traditional metallocene laboratory targets, students synthesize Cp[subscript 2]TiCl[subscript 2], bis([eta][superscript 5]-cyclopentadienyl)dichloridotitanium(IV), from the mildly moisture-sensitive cis-TiCl[subscript 4](thf)[subscript 2]. Air-free handling techniques are emphasized, but the (mostly) air-stable,…

Scanning probe microscopy such as atomic force microscopy has become increasingly integrated and relevant in undergraduate laboratory investigations. As the "hands and eyes of the nanoworld", atomic force microscopes (AFMs) continue to be used to innovate the nanowriting process for data storage and in the exploration of novel materials…

A new undergraduate organic laboratory experiment has been developed and implemented for the Ugi three-component synthesis of the topical anesthetic lidocaine with excellent atom economy. Paraformaldehyde, diethylamine, and 2,6-dimethylphenyl isocyanide were combined and conveniently stirred at room temperature for a week in methanol with acetic…

Course-based undergraduate research experiences (CUREs) are a promising approach for incorporating inquiry-based instruction into the undergraduate chemistry laboratory curriculum. This study used data from a national survey of inorganic chemistry faculty members (n = 142) to investigate CURE implementation in the inorganic chemistry instructional…

Undergraduate research experience is critical to success in postgraduate research settings. The recent movement away from "cookbook" style laboratories to course-based undergraduate research experiences (CUREs) in undergraduate laboratories has allowed universities to provide inclusive research experience while bypassing the limitations…

Mercury beating heart (MBH) is a well-known demonstration of redox processes. However, the development and application of the MBH system are significantly restricted due to its safety issues. Here, a direct current electric field-enabled gallium-based liquid metal heartbeat in a salt solution or alkaline solution is introduced as a demonstration…

Recently, two-dimensional (2D) nanostructures, such as graphene and few-layer MoS[subscript 2], have been applied to wide fields based on their intriguing performances, and they contribute to developments of clean energy, biomedicine, and environmental protection. The synthesis of 2D nanostructures involves chemistry, materials, and…

Fieldwork is a meaningful and authentic learning experience that is rarely included in undergraduate chemistry courses. In this laboratory, we visited a hot spot of perfluoroalkyl acid (PFAA) contamination identified in 2012, in Binbrook, Ontario, Canada, a 1 h drive from the University of Toronto. The persistence and unique environmental…

A laboratory activity was developed to teach freezing point depression and colligative properties to introductory-level chemistry students. The laboratory uses food-grade reagents and is delivered in two units that can be taught in a single 2 hour session or two separate sessions. The total cost of the consumables is 1 USD. In the first part of…

This undergraduate laboratory experiment is designed for first-year general chemistry students with the goal of introducing the brilliant colors and magnetic properties of transition metal complexes within a bioinorganic/cell biology context. In the first laboratory period, a coordination complex formed from ferric chloride and maltol is…

A new undergraduate organic laboratory experiment has been developed for amide bond formation between biorenewable 2-furoic acid and either of two substituted piperazines to prepare medicinally relevant amide products using a procedure with industrial significance. The reactions proceeded smoothly under ambient conditions using the combination of…

A new method to determine a ternary phase diagram of benzene-acetic acid-water system is provided to upper-division undergraduate students. The partially miscible liquid phase region can be accurately constructed using isothermal titration microcalorimetry (ITC). Compared with the traditional visual method, ITC can provide precise data and more…

Creativity plays an important role in mathematics, but it can be overlooked in undergraduate courses. This article describes three ways an existing first-year math seminar was modified to increase its focus on creativity: introducing readings and discussions related to creativity, drawing connections to creativity in other disciplines, and adding…

This article is based on a research whose objective was to create and analyze the undergraduate business model taxonomy in Distance Education (DE) modality at private Higher Education Institutions in Brazil. As methodological procedure, a survey was conducted from August to November 2017, with 43 Brazilian institutions and a cluster analysis. The…

Evaluator education programs have developed to help support the growth of professional evaluators and improve evaluation practice. Empirical research has described where and how evaluation is taught at the graduate level of education, but little is known about the undergraduate level. This study empirically explores how, if at all, evaluation is…
