Hands-on laboratory experiences are a key part of all engineering programs. Currently there is high demand for online engineering courses, but offering lab experiences online still remain a great challenge. Remote laboratories have been under development for more than 20 years and are part of a bigger category, called online laboratories, which…

The importance of utilizing spectroscopic techniques for unraveling structural and compositional changes in nonreacting and reacting systems is unquestionable. Nowadays, efforts are directed towards the introduction of relevant spectroscopic techniques to undergraduate students in order to prepare them for future careers in industry and academia,…

Thermodynamic characterization of micelle formation from an ionic surfactant in aqueous solutions is a classic experiment in physical chemistry. The critical micelle concentration (CMC) and the degree of micelle ionization ([alpha)] can be directly obtained by conductimetry, then thermodynamic parameters ([delta]G[subscript m][superscript o],…

The Physics Laboratory of the Hellenic Open University has constructed a small scale and low cost air shower detector suitable for operation inside the classroom or school laboratory ([mu]Cosmics detector). In this work we present some of the educational activities foreseen with the [mu]Cosmics air shower detector, as well as the assessment of a…

The free radical chlorination of an alkane experiment is often used in the undergraduate laboratory curriculum to introduce students to the free radical mechanism, substituent effects, intermediate stability, and the relative reactivity of radicals. In this experiment, students monochlorinate multiple alkanes and analyze the reaction mixture using…

Keto-enol tautomerism is a special example of structural isomerism. In this experiment, 6-chlorofulvene is predominantly yielded during the chlorination reaction of 6'-hydroxyfulvene with POCl[subscript 3] in the presence of DMF. The high regioselectivity of this reaction is dominated by intramolecular hydrogen-bonding and steric hindrance,…

Since the sudden emergence of COVID-19 global pandemic, all educational institutions have looked to move resources and delivery online. Some institutions had already embraced delivering instruction in this way; however, broader adaptation to this teaching style is new to many educators. While the teaching of theoretical concepts is more easily…

In this study a survey was developed to investigate students' engagement during general chemistry laboratory sessions. Aspects of engagement surveyed included cognitive, behavioral, and emotional engagement, and the survey items were focused on activities during the pre-laboratory introduction, laboratory procedures, and data collection.…

Chemical waste should be reduced to minimize environmental pollution, and it is important that the amount of waste is minimized in chemistry teaching laboratories to reduce the negative impact on environment as well as the disposal costs of university. There are several ways to minimize the waste generated in chemistry teaching laboratories,…

In this brief experiment, students create a superhydrophobic surface as an application of polar--nonpolar interactions and redox chemistry. Half of a zincgalvanized steel strip is coated in copper nanoparticles through electroless deposition. A layer of nonpolar octadecanethiol is added to half of that copper surface. Students classify the three…

A laboratory activity is described for senior high school or first year undergraduate level students that illustrates key concepts linked to extractive metallurgy. This experiment demonstrates preferential binding of a methoxyphenolic oxime ligand to Cu[superscript 2+] in the presence of other transition metal ions in aqueous solution. The…

The dissertation is composed of two sections. The first section is composed of chapters one, two, and three and describes the study of macrocyclic [beta]-hairpin peptides derived from [beta]-sheet peptides. The second section is composed of chapters four and five and discusses the curricular innovations made to support the remote instruction of an…

The purpose of this study was to develop a modern experimental apparatus using an Arduino with LabVIEW instead of the classical experiment. The wavelength of the sound was determined using the resonance of an air column. The smartphone app was used to generate the desired frequencies. A sound intensity and ultrasonic sensor was used to read the…

The university traditionally has been the foundation for young adults' professional development, yet the proclivity toward safety culture has garnered less focus in higher education than in the workforce. A survey of faculty at a medium-sized, research-active, private institution revealed specific areas of policy noncompliance as well as specific…

This article describes how the Sichuan University - Pittsburgh Institute has embraced new methods and new technologies to ensure high-quality laboratory teaching during the COVID-19 pandemic. Taking Mechanical Measurements 1 course as an example, this paper introduces two lab projects that were successfully transferred into online experiments…
