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…

Chemical engineers must learn to connect concepts across vastly different scales, spanning from molecular structures to industrial processes. Here, we explore the use of a virtual-reality simulation with a companion video of an experiment to help undergraduate students connect nanoscale fundamentals to macroscale engineering observations.

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…

The flue gas from waste incineration power plants contains high-level zinc species that may deactivate the catalyst for selective catalytic reduction (SCR) of nitrogen oxides (NO[subscript x]) with NH[subscript 3]. A comparison experiment was designed to investigate the effect of different types and Zn/Ce molar ratios on the performance of…

This paper reports the quantification of Ca, Mg, and Fe as micronutrients in different vegetables (spinach, sugar beets, and carrots) from raw and processed samples. Simple extraction procedures, titrations, and spectrophotometric analysis were used to determine the amounts of micronutrients before and after cooking. From the obtained results, an…

A laboratory experiment was performed using tetra-n-butylammonium bromide (TBAB) ionic semiclathrate hydrate, a crystalline compound. Ionic semiclathrate hydrates have unique properties, and hence, novel technologies utilizing the ionic semiclathrate hydrates have been proposed to date. Thus, students could learn fundamentals of functional…

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…

The COVID-19 epidemic adversely impacted chemical engineering experiments(CEEs). Students underwent online learning, i.e., software simulation of the CEE course, instead of laboratory learning. A questionnaire survey revealed that students exhibited low enthusiasm for online learning, showing that online courses cannot ensure learning quality.…

The electrolysis of water to produce hydrogen is a critical step in many green chemistry processes. The key to the efficiency of water electrolysis is the synthesis of an appropriate electrocatalyst. Three-dimensional (3D) printing is an increasingly important part of many industrial processes. In this study, we propose an efficient laboratory…

During the SARS-2-COVID pandemic our institution sought to continue the teaching and learning of experimental laboratories by designing, assembling, and delivering a microscale chemistry kit to the students' homes. Thanks to this approach students were able to perform [approximately]25 experiments during each one of the Fall 2020 and Spring 2021…

This work presents an outline for a full-quartile design-based learning laboratory-based course suitable for final year Bachelor's students. The course has been run for 5 years in the department of Chemical Engineering and Chemistry. The course attempts to provide a complete laboratory experience for its students, including an authentic research…

Chemical engineering is a challenging field to explain to first-year students. Food production processes are a safe and accessible way to introduce the students to basic engineering concepts. Modernist cuisine -- using scientific methods and engineering techniques to enhance classical cooking -- was used as a hook to capture the attention of…

An experimental procedure is presented that was developed by fifth-year chemical engineering and industrial chemistry undergraduates at the Federal University of Rio de Janeiro doing the discipline on Experimental Organic Technology. The aim of this study was to apply the solvatochromic effect of the dye Nile Blue chloride to the characterization…

To inspire upper-division undergraduate students to gain a deeper understanding of biorefinery, an experiment related to biofuels and lignin-based sunscreen products from corncob was performed in multiple offerings of a summer-semester class. Specifically, corncobs were pretreated with 1% H[subscript 2]SO[subscript 4] to obtain hemicellulose…

Rapid development in the field of reticular chemistry has allowed scientists ever-increasing control over the design and synthesis of crystalline porous materials. The promise that this field has in the development of next-generation materials for numerous applications (gas storage and separation, catalysis, chemical sensing, electronics) relies…
