This paper describes the combination of problem-based learning (PBL) and simulation tools in the chemical engineering unit operation laboratory course, focusing on heat transfer concepts using a shell-and-tube heat exchanger experiment. This approach has significantly enhanced student learning outcomes by bridging theory with practice, fostering a…

A multistep assembly of gold nanoparticle self-assembled monolayers (SAMs) on glass surfaces is proposed, as a third-year undergraduate experiment. The process includes self-assembly (SA) and electrostatic self-assembly (ESA) methods, which are central approaches in modern surface and materials engineering. The products are analyzed using…

This paper describes an innovative, new, laboratory experiment conceived as a Senior Capstone Project by the student authors to provide experience with heat pipes for students in our junior-year Process Laboratory course at the University of Utah. Heat pipes can transport energy over long distances with minimal temperature gradients and no moving…

This article describes two sets of experiments designed to enhance the understanding of colloidal systems. These experiments were designed as a part of the theme "Colloids: Where Science Meets Engineering" taught in the Department of Chemical Engineering and additionally offered to physics, chemistry, and materials science departments as…

This research aimed to explore the effects of a virtual lab (VL) and a Microcomputer-based Lab (MBL) on students' performance in scientific modeling. A web-based virtual lab and a low-cost MBL were proposed to help first-year engineering students build scientific models. Empirical research was done in a slope motion experiment. The participants…

The development of a QR code as a barcode label contains information about the item to which it is attached. However, information on QR code development in engineering science laboratories is still limited. The aim of this research is to design the QR code lab manual for laboratory work in polytechnics engineering science course. In addition, the…

Nanoscale phenomena are under increasingly intense investigation both in academia and industry. The unique physical and chemical properties stemming from their high surface area and confined space lead to properties that are distinct from atomic and bulk materials. Students need experience in nanoscience to enter this growing field of nanoscience…

The introduction of the Wireless Smart Cart by PASCO scientific in April 2016 has ushered in a paradigm shift in the design and implementation of low-cost undergraduate physics and engineering laboratory experiments. The use of smartphones in experimental physics is by now widely accepted and documented. The smart cart in combination with…

The rapid academic and industrial development of nanotechnology has led to its implementation in laboratory teaching for undergraduate-level chemistry and engineering students. This laboratory experiment introduces the galvanic replacement reaction for synthesis of hollow metal nanoparticles and investigates the optical properties of these…

This article describes an experiment that can be done in the classroom in a simple way, with the support of a "homemade" device or as a laboratory practice with the support of PASCO equipment. Through a theory-practice sequence, kinematic and dynamic equations were checked with qualitative and quantitative analysis, emphasizing the…

Heat and temperature concepts are found at all levels in the science curricula and are well-known for creating conceptual difficulties for learners. Students have difficulty understanding concepts related to heat, temperature, and thermal radiation. Inquiry-based pedagogies that can foster the learning of these difficult concepts are needed.…

The increased worldwide exploitation of nanomaterials has reinforced the importance of introducing nanoscale aspects into the undergraduate and graduate curriculum. To meet this need, a novel nano-laboratory module was developed and successfully performed by science and engineering students. The main goal of the experiment was to accurately…

Bioprocess engineering is a highly interdisciplinary field of study which is strongly benefited by practical courses where students can actively experience the interconnection between biology, engineering, and physical sciences. This work describes a lab course developed for 2nd year undergraduate students of bioprocess engineering and related…

In recent years, nanoscience and nanotechnology have been drawing enormous attention due to the numerous applications of nanomaterials. In an attempt to nurture interest towards these areas in young minds and to develop the next generation of environmentally conscious scientists and engineers, this new laboratory module focuses on the green and…

Numerous nanoparticle (NP) fabrication methodologies employ "bottom-up" syntheses, which may result in heterogeneous mixtures of NPs or may require toxic capping agents to reduce NP polydispersity. Tangential flow filtration (TFF) is an alternative "green" technique for the purification, concentration, and size-selection of…
