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…

Molecular imprinting technology holds significant potential for applications in chemical analysis and detection. In order to integrate the fundamental knowledge of polymer chemistry, electrochemistry, and analytical chemistry with practical applications and cutting-edge research, we proposed a comprehensive experiment of the preparation,…

Objective: This study examined the liking of fruits and vegetables among college students and the relationship between skin carotenoid levels and liking of fruits and vegetables. Participants: Sixty-six undergraduate students enrolled at a university in the southeastern United States participated in this study beginning August 2019. Methods: Skin…

This dissertation contains findings from two research projects. The first research area focused on assessing engineering students problem solving skills. Problem solving related to two material and energy balance topics--vapor liquid equilibrium and reacting systems with recycle - were examined first followed by a more holistic analysis across two…

A straightforward protocol for the preparation of the colorful and air-stable diphenyl ditelluride is described. In one laboratory session, students isolate their product and characterize it via melting point determination, mass spectrometry, and NMR spectroscopy ([superscript 1]H, [superscript 13]C­{[superscript 1]H}, and [superscript…

In this laboratory experiment, first-semester organic chemistry students use mechanistic reasoning to propose possible outcomes for the reaction of vanillin isobutyrate with a hydride source. The students subsequently run the reaction, isolate the product, and acquire its infrared spectrum. The experiment provides students with the opportunity to…

The dangers of organic dye pollutants and environmental pollution improvement through photocatalytic degradation are important courses in applied chemistry programs in universities. Zinc oxide (ZnO)-based nanomaterials are potent catalytic agents against organic dyes, but few experiments are available for students to understand their role and…

The adulteration of food products, including honeys and syrups, is of growing concern in global food markets. Detecting adulterated food products can be difficult using traditional analytical methodologies because of complex sample matrices or poor separation of key compounds. NMR is an analytical tool that circumvents some of these issues by…

Chemistry undergraduate curricula typically place Nuclear Magnetic Resonance (NMR) lectures under either Organic Chemistry or Spectroscopy courses, aiming for students to acquire basic knowledge for the determination of the structure of simple organic compounds. On the other hand, regarding laboratory practice, NMR is frequently disregarded by…

An ICP-MS simulation was developed to support the teaching of inductively coupled plasma-mass spectrometry. The app enables students to conduct the quantification of selenium in a nutritional supplement, monitor the uptake of metallodrugs by cells, and perform qualitative analysis of gunshot residue. The experiments teach a range of analytical…

A didactic sequence is proposed using an infrared puzzle and a didactic questionnaire for the teaching-learning of infrared spectroscopy at the upper secondary level. The didactic sequence that was designed was implemented in person in the subject of Chemistry IV at the high school level, corresponding to the sixth semester of the curriculum of…

The pharmaceutical and medicine manufacturing industry has become the largest industrial sector for the employment of chemists, indicating a need for experiments with a pharmaceutical sciences context in the undergraduate chemistry curriculum. In the pharmaceutical industry, testing drug dissolution is a key analytical task for solid oral dosage…

Infrared spectroscopy (IR) is a staple structural elucidation and characterization technique because of its ability to identify functional groups and its ease of use. Interestingly, it allows the capture of electronic effects via their influence on the bond strength of "probes", such as the carbonyl group and also offers a wealth of…

Evidence from fMRI research indicates that individual creative thinking ability -- defined as performance on divergent thinking tasks, subjectively assessed by human raters -- can be predicted based on the strength of functional connectivity (FC) between the brain's default mode network (DMN) and frontoparietal control network (FPCN). Here, we…

Ion channel sensors have several applications including DNA sequencing, biothreat detection, and medical applications. Ion channel sensors mimic the selective transport mechanism of cell membranes and can detect a wide range of analytes at the molecule level. Analytes are sensed through changes in signal patterns. Papers in the literature have…
