The use of radioactive isotopes in radioactive decay studies can be a problem due to the manipulation of radioisotopes, expensive equipment, and the difficulty of finding samples with a reasonable half-life (between 1 and 10 min). In this paper, we present a mock-up of a Geiger-Mu¨ller counter plus three fictitious radioisotopes. They form an…

Distance learning in physics is still facing challenges, mainly due to the difficult access to a laboratory for practical work. Practical work is an essential part of the physics classroom because it allows students to interact with authentic physics phenomena and develop their scientific abilities. In this paper, we propose alternative…

Polymer Chemistry is a subject in the Chemistry Programs, student have a natural curiosity about polymeric materials, that we use in our everyday activities. Our proposal is to apply cooperative learning in the Interfacial polymerization of Nylon 6,10 experimentation. The specific objectives of our project can be summarized as: To identify the…

Organizing undergraduates in chemistry, energy engineering, and chemical engineering specialties to participate in an energy transformation experiment can encourage them to think about the impact of human activities on nature and stimulate them to learn more about the topic. This laboratory experiment demonstrates a general approach to the…

Lateral flow assays play a key role in mass testing for COVID-19, for example, in schools. The red color of the detection lines is caused by gold nanoparticles that are conjugated to antibodies. Hence, these tests present a very topical learning opportunity in the emerging field of nanoscience. To highlight the role of gold nanoparticles, a…

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…

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…

Undergraduate organic chemistry laboratory courses act as a baseline for introductory scientific experimentation. These courses provide students with the knowledge and skills for their future careers. The traditional lab is conducted by providing a structured protocol of the experiment for the students to follow and reproduce the assigned task…

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…

As quantum information science and technology (QIST) is becoming more prevalent and occurring not only in research labs but also in industry, many educators are considering how best to incorporate learning about quantum mechanics into various levels of education. Although much of the focus has been on quantum concepts in nonlab courses, current…

During the COVID-19 pandemic and subsequent lockdown, both schools and universities faced significant challenges in moving teaching from an in-situ setting to a remote one, this included laboratory experiments. This paper presents an experiment developed to use a phone's in built pressure sensor, common to most smart phones. By using this sensor…

The [2 + 2] photocycloaddition reaction of olefins is an effective, atom-economical approach to produce cyclobutane compounds in organic synthetic chemistry, and they usually exhibit high regioselectivity and stereoselectivity. Here we devised a solid-state [2 + 2] photocycloaddition experiment that introduces senior undergraduate students with…

Millions of people do not have access to clean drinking water; thus, cost-efficient water treatment systems are vital. Chemists, environmentalists, technicians, and engineers will be the professionals making breakthroughs in this industry. This laboratory experiment aims to introduce undergraduate students to the removal of pollutants from water…

[This paper is part of the Focused Collection on Instructional labs: Improving traditions and new directions.] This paper presents a historical analysis of the development, implementation, research, and assessment of an evidence-based introductory algebra-based physics course. The course is laboratory based and taught with an inquiry-based…

In all fields of chemistry, it has become essential to use quantum chemical calculations and machine learning for explaining and predicting chemical phenomena. However, it is challenging to apply textbook knowledge to practical research. In this study, we developed teaching material based on computational chemistry to promote the integration of…
