The crystalline sponge method allows for direct and precise molecular structure determination of liquid and gaseous targets and thus has been recognized as a revolutionary breakthrough in crystallography. To expose undergraduates to this cutting-edge technique, we have developed a comprehensive laboratory experiment with reaction conditions and…

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…

In this paper, we present a concise and technique-heavy route to the synthesis of dimedone for a second-year organic chemistry curriculum. Our preparation of dimedone guides students through a Michael addition followed by a Dieckmann cyclization, basic ester hydrolysis, and thermal decarboxylation, while allowing time for mechanistic discussion…

The field of DNA nanotechnology has grown rapidly in the past decade and has expanded to multiple laboratories. While lectures in DNA nanotechnology have been introduced in some institutions, laboratory components at the undergraduate level are still lacking. Undergraduate students predominantly learn about DNA nanotechnology through their…

With the increase of waste paper, environmental pollution and atmospheric impact have become global problems. The cellulose contained in waste paper has the advantages of being renewable and biodegradable and can be applied to many fields to achieve sustainable development. At present, thermal management materials, as a new type of material, have…

As electrochemistry continues to gain broader acceptance and use within the organic chemistry community, it is important that advanced undergraduate students are exposed to fundamental and practical knowledge of electrochemical applications for chemical synthesis. Herein, we describe the development of an undergraduate laboratory experience that…

Research has shown that the use of practical examples in undergraduate education promotes the retention of historically underrepresented students in STEM majors and lowers achievement gaps within courses. Since many students of color and women aspire toward careers in healthcare and the pharmaceutical industry, efforts to incorporate medicinal…

Undergraduate physics laboratory exercises are very important in shaping students' attitude to science, especially for future teachers. Recently, it is necessary to look for ways to easily create large quantities of experimental sets, not only for institutional use, but also for sets that can be produced in large quantities and distributed for use…

Undergraduate chemistry laboratory instruction can be considered from many perspectives and addresses multiple educational aims. We critically assess an inventory of "Cognitive Tasks of Experimental Research" for its applicability to chemistry laboratory teaching, and then apply it to an integrated upper-level laboratory course as an…

We have investigated the motion of water flow through glass tubes of different shapes by calculating the value of the Reynolds number denoted as Re. We know that at a given flow rate the value of Re determines the type of flow being classified as laminar, transitional or tubulent. The dependence of Re in different configurations of glass tubes as…

A student experiment that uses QuEChERS (quick, easy, cheap, effective, rugged, and safe) methodology for extraction and HPLC for quantitative determination of tocopherols from seeds and nuts is described here. Chromatographic separation is achieved by using a pentafluorophenyl stationary phase which gives enhanced separation of the tocopherols…

The laboratory experiment presented here describes the use of a calcium ion-selective electrode (Ca-ISE) to determine the concentration of zinc in a supplement tablet. This approach was developed to show students how to expand the range of applications of Ca-ISE to enable the determination of metal ions other than Ca[superscript 2+]. To determine…

This report presents an interdisciplinary approach used in undergraduate laboratory classes to bridge the gap between scientific advances, engineering efforts, and practical applications in daily life. The field of biointegrated electronics is highlighted as an excellent opportunity for building interdisciplinary learning models, leveraging…

A two-component undergraduate laboratory experience has been developed by students in a senior level capstone course. The first component is a 3 h laboratory experience dedicated to the rapid synthesis of a metal-organic framework (MOF-808) in aqueous solution using readily available reagents and equipment. During the second component, MOF-808 was…

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…
