Vimoshini Pragash; Meran Keshawa Ediriweera – Biochemistry and Molecular Biology Education, 2025
The Folch method is a commonly employed, simple biochemical procedure used to extract fat from food items and biological samples in biochemistry laboratories. The iodine number of fat reflects its degree of unsaturation. In the present study, the iodine number of fat extracted using the Folch method from cow milk, goat milk, chicken egg yolk and…

Ângelo Luís; Fernanda Domingues – Biochemistry and Molecular Biology Education, 2025
Bacteria have developed a cell-to-cell communication system called quorum sensing (QS), allowing them to regulate group behavior and synchronize the expression of virulence factors, responsible for increasing their infection capacity and resistance to antimicrobials. Although the control of microbial infections through the inhibition of microbial…

Fluorescence-related experimental techniques play an important role in biochemistry, molecular biology, and cell biology. However, fluorescence-related experiments are rarely included in the laboratory courses of most Chinese universities. This is mainly due to the conflict between large class size (50-60 students in one room) and funding/space…

Owing to the critical role of stereochemistry in biotechnology, medicine, and industry, it must be well represented in undergraduate lab curricula. To achieve these stereochemical laboratory requirements without sacrificing existing lab techniques, we modified two standard laboratory experiments to include chiral GC analysis as follows. (1) The…

The ability to elucidate the structure of organic compounds from their nuclear magnetic resonance (NMR), infrared (IR), and mass spectrometry (MS) spectra is an essential skill, particularly for those engaged in the fields of synthetic and analytical organic chemistry. Spectral analysis constitutes a fundamental component of the curriculum for all…

Jixin Wang; Wenshui Zhou; Yin Li; Mei Yu; Zheng Zhu – Journal of Chemical Education, 2024
By hosting a college students' laboratory skills contest, we provide an interesting activity for students to cultivate good laboratory practices and thereby improve their laboratory skills. The substance of this contest is the detection of the hardness of water, which involves numerous laboratory skills such as solution preparation, weight by…

We present the development and evaluation of "da Vinci's Curse", a chemistry escape room experience designed to consolidate laboratory skills in a fun and interactive setting. Inspired by the maestro, Leonardo da Vinci, the escape room challenges students to complete a series of puzzles in teams to escape "da Vinci's Curse".…

Understanding potentiometry is a difficult task when students in initial courses of Analytical Chemistry are first introduced to instrumental techniques. The closest instrument to them is a pH meter, which is frequently used as a "black box", without a real understanding of how it works. Here we present the assembly of jelly modules that…

Affect and emotions matter to science learning. They also matter because they are integral to science identity formation and sense of belonging. This study aims to foreground the epistemic and affective character of laboratory work in higher science education by conceptualizing it as epistemic practice, in which students activate their body and…

Chemometric techniques such as partial least-squares (PLS) regression have been applied with huge success to a wide array of chemical problems including multicomponent analysis of analytes in complex mixtures. Despite this, there are few examples of laboratory pedagogical exercises that involve students in the acquisition of chemical data from…

Margaret K. Meadows – Journal of Chemical Education, 2024
This paper describes the design, implementation, and evaluation of an inquiry-based laboratory for sophomore-level organic chemistry into a mostly cookbook, existing laboratory curriculum. For the laboratory, students were required to generate their own procedures and use their own recorded data from prior laboratory assignments to identify an…

Andrea D. Merry; John A. Means; Tim E. Hall – Journal of Chemical Education, 2024
In this laboratory activity, students were tasked with determining the heat of combustion for each of three common sugar substitutes: saccharin, aspartame, and sucralose. The heats of combustion were determined via three different methods: bomb calorimetry, heats of formation derived from semiempirical calculations, and tabulated average bond…

The concept of co-amorphous systems is introduced in an integrated laboratory experiment, designed for advanced chemistry students, using solvent-free, environmentally friendly mechanochemistry. The dual-drug naproxen-cimetidine co-amorphous system (NPX-CIM) is investigated as an example of the emergent field of medicinal mechanochemistry.…
