Purpose: Hands-on training in tissue engineering is often associated with specialized labs and expensive equipment, such as CO[subscript 2] incubators. To minimize the use of costly commercial incubators and provide a more vivid engineering experience in a biology lab, we present a hands-on project that introduces medium to large groups of…

We describe an experiment in which students use research-grade instrumentation to collect gas adsorption data in triplicate in a single 3 h laboratory period. The experiment reinforces the thermodynamic concepts taught in upper level physical chemistry courses and hands-on experience with instrumentation used in research laboratories. The speed of…

Experimental electrochemistry offers unique opportunities for interactive instruction at all levels of education; however, widespread adoption in curricula is hindered by high costs associated with electrochemical instrumentation. Thus, the development of affordable instruments represents an essential step toward making electrochemistry accessible…

There currently exists a significant deficiency in the nuclear chemistry workforce within the United States, despite its importance in areas of medicine, national security, and energy. Poor coverage of this topic across many chemistry departments at the undergraduate level likely contributes to this shortage. Increasing interest and hands-on…

Fluorescence-related experimental techniques play an important role in biochemistry, molecular biology, and cell biology. However, fluorescence-related experiments are rarely included in the laboratory courses of most Chinese universities. This is mainly due to the conflict between large class size (50-60 students in one room) and funding/space…

This laboratory experiment offers a research-style experience designed for senior undergraduate students in a multidisciplinary laboratory setting. The experiment focuses on the synthesis, characterization, and application of a cation-exchange membrane made of COF-SO[subscript 3]Na/PAN for ion separation. By participating in this practical…

Mass spectrometers are ever-increasingly powerful, user-friendly, and affordable. Thus, the addition of mass spectrometry experiments into the undergraduate laboratory curriculum is now both feasible and an effective tool to introduce students to relevant instrumentation. Here an experiment demonstrating the use of a high-resolution electrospray…

Providing hands-on practical education without access to laboratories during the COVID-19 pandemic has required creativity and innovation. In this paper, co-authored by academic staff and students, we describe an at-home mobile phone-based 'spectrophotometer' experiment used in an introductory undergraduate biology course. Using colour picker…

Student-built photometers are recognized as being useful tools in teaching laboratories that help students understand the concepts behind experimental measurements, and several devices have been reported that employ photoresistors as the detector of choice. We demonstrate here an improvement over these instruments and the analyses thereof,…

The synthesis of substituted 1,4-benzoquinones, a biologically important class of compounds, was developed using [mu]-oxodi(phenyliodanyl) diacetate, a (diacetoxyiodo)benzene-based oxidizing reagent, in order to introduce second-year undergraduate organic laboratory students in their second semester or advanced organic students to increasingly…

The concepts of phospholipase activity is often taught in undergraduate biology and biochemistry classes and reinforced in laboratory exercises. However, very rarely does the design of these exercises allow students to directly gain experience in the use of modern instruments such as digital imaging systems and fluorescence spectrophotometers. The…

The time-resolved detection of very low intensity light emission has become an essential capability in many areas of science including molecular biology, fluorimetry, DNA sequencing, virus detection, nanoparticle research, and optical materials development. Among the most basic techniques for the detection of rapidly fluctuating low-intensity…

Lab-on-a-chip devices are a critical and emerging chemical technology. New pedagogical tactics that effectively capture both analytical chemistry concepts along with the design elements unique to these devices are necessary for effective integration in the undergraduate chemistry curriculum. This article develops a design-based learning laboratory…

As data science and instrumentation become key practices in common careers ranging from medicine to agriscience, chemistry as a core introductory course must introduce such topics to students early and at an accessible level. Advanced data acquisition and data science generally require expensive precision instrumentation and massive computation,…

Facing calls for greater emphasis on STEM education in primary school classrooms, teachers may be anxious because of limited exposure to STEM in their own education. The Australian Curriculum: Technologies is new and many teachers are not familiar with its content. Hence both in-service and pre-service teachers (PSTs) require preparation. This…
