For the present lab demonstration, we have developed fluorescent indicators to detect the end point in microscale redox titration of ferrous ions in permanganometry, cerimetry, and dichrometry. Microscale redox titrations were carried out effectively in micromolar(µM) concentrations and semi-microvolumes of the analytes. At the end point,…

Biopharmaceuticals are gaining high relevance in the pharmaceutical industry and market, due to their specific design for many therapeutic conditions and ability to restore biological functions. As a matter of fact, gene therapy products have been studied and developed in the past several years, and more recently, they arouse real interest as…

Lateral flow assays (LFAs) have been used extensively for diagnosis of various diseases and conditions because they are inexpensive, rapid, robust, and easy to use. Incorporating LFAs into undergraduate chemistry courses could enrich the curricula by providing the students with a real-world application of analytical chemistry concepts,…

The development and application of a simulator designed with Excel spreadsheets to teach procedural skills in atomic absorption spectrometry and atomic emission spectrometry are proposed. For the development of the simulator, different analytical procedures were followed including analysis of pharmaceutical, forensic, and environmental samples.…

Buckminsterfullerene (C[subscript 60]), along with diamond and graphite, appears in many chemistry textbooks as an example of an allotrope of carbon. This communication describes a hands-on activity to explore the characteristic structure of C[subscript 60] through the construction of a structural model using transistors and plastic tubes…

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…

Evidence from the past several decades has repeatedly found that the chemical enterprise presents systemic barriers for people with marginalized identities. Initiatives and actions that remove systemic barriers and support the success of all students, especially those from equity-deserving groups, are essential. However, fostering a culture of…

We describe programs developed and implemented at the University of Wisconsin-Madison Department of Chemistry aimed at increasing representation and improving outcomes for graduate students from underrepresented minority groups. We briefly describe our Research Experience for Undergraduate (REU), Chemistry Opportunities (CHOPS), Catalyst, and…

Calls for diversity, inclusion, and equity in chemistry and science education have been ongoing. However, some faculty may find it difficult to challenge systemic inequities due to their pervasiveness. We posit that one working area for addressing systemic inequities in chemistry and science education is the removal of grading on a curve from our…

Several studies have highlighted the positive effects that active learning may have on student engagement and performance. However, the influence of active learning strategies is mediated by several factors, including the nature of the learning environment and the cognitive level of in-class tasks. These factors can affect different dimensions of…

Situational simulation teaching method (SST mentioned below) is a mature teaching method that has been applied. It has been widely used in foreign language, law, management, clinical and other fields, and has been proved to have good teaching effect. The quality of teachers is the key to improve the international competitiveness of China's…

The lack in process intensification (PI) training may be limiting processes to achieve sustainability goals. This project developed a hands-on course on intensified membrane processes to address knowledge gaps in PI. Bench-scale activities introduced concepts of membrane separation, operating engineering-scale modules provided a near-industrial…

Chemical tests (qualitative analysis) on functional groups may improve students' understanding of basic concepts about the structure of organic compounds and their reactivity. However, upper-secondary school students have difficulties in learning organic qualitative analysis. This research has studied whether the gender of students and school-type…

Over the years it has become more common for practitioners to use the NGSS scientific practices to inform curricula at the undergraduate level. One of these practices is argumentation, the process of engaging in argument from evidence. Argumentation is an important part of the scientific process because scientists must make claims about their…

Electrochromism encompasses reversible changes of material's optical properties (color, opacity) under the influence of an external electric current or applied voltage. The effect has been known for decades, but its importance continues to grow due to the rapid development of smart systems and the accompanying demand to build devices that consume…
