Microfluidics has attracted widespread interest in the fields of chemicals, materials, pharmaceuticals, biology, etc. Integrating low-cost automation based on open-source hardware/software to improve lab security and reduce time consumption is demanded in microchemical processing. In this work, we developed a "do it yourself"…

Enzymes, enzymatic kinetics, and enzyme inhibition are topics covered in undergraduate biochemistry textbooks, having perceptible relevance to everyday life. The experimental use of enzymes involved in basic physiologic processes may be of utmost pedagogic interest because they bring evidence on how a significant number of drugs are used to…

This paper describes the application of an accessible, benchtop mass spectrometer using an Atmospheric Solids Analysis Probe (ASAP) for easy sample introduction, coupled with Atmospheric Pressure Chemical Ionization (APCI) as a soft ionization technique, to the inquiry-based identification of the metal composition of alloys, including coins.…

A collection of four activities for science outreach events was developed to teach middle school students about the temperature dependence of scientific phenomena. Procedures are described for four interactive demonstrations on phase changes, fluorescence, viscosity effects on diffusion, and conductivity. Each hands-on activity helps students…

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…

We provide an update on the "electrochemistry designette" in relation to its pedagogical effectiveness to students and experiential learning. We have previously proposed that the designette be applied as an assessment tool to measure the students' competence on electrochemical principles through a series of objective metrics. Based on…

A two-part workshop connecting environmental science topics and green chemistry principles for undergraduate students is described. Students first collect acorns and rusted metal for dye and mordant baths. After 2 weeks they are invited back to tie-dye cotton fabric using dye baths prepared from steeped acorns and modify these colors using mordant…

We here propose a simple and fast hands-on activity requiring limited equipment, to introduce students of various levels (bachelor's or high school) and backgrounds (from science to arts) to the chemistry of color. The different colors of stained glass are replicated through the deposition, on ordinary glass slides, of silica coatings colored by…

The COVID-19 pandemic has significantly affected teaching processes worldwide, particularly in laboratory-intensive courses. To adapt, online experiments have been implemented globally. In response, educators at the Department of Chemistry, Chulalongkorn University, developed a Lab@Home chemistry experiment for their general chemistry lab course…

Lampworking is a valuable skill for students in Chemistry and others in science, technology, engineering, and math (STEM) related fields. The activity described here provides instructors the resources to both learn and teach the fundamentals of lampworking. Soft glass, which can be shaped and fused with a Bunsen burner, is used to improve the…

Hands-on chemistry experiments often stimulate students' curiosity about this subject, but blind or visually impaired (BVI) students usually do not get to participate in such hands-on activities. Thanks to adaptive methods and assisting technology, BVI students can actively participate in chemistry experiments. In this study, chemical laboratory…

Green chemistry provides unique opportunities for student engagement through K-12 and community outreach. As a platform for safe, engaging outreach, green chemistry activities allow for hands-on approaches to introducing science and chemistry concepts in informal settings. Green chemistry outreach also is a means for American Chemical Society…

Motivational hands-on workshops for grade-school level future scientists are needed to inspire young and receptive minds. Described here is an educational event, titled "Inspiring Future Rocket Chemists", with hands-on laboratory exercises demonstrating the fundamentals of rocket flight and live chemistry demonstrations illustrating the…

Level 3 characteristics are increasingly important for fingerprint identification, particularly when the fingerprints are problematic and lack level 2 details. In practice, no reliable visualization methods for level 3 features are transferred into a course for the general public, forensic students, or investigators. Our group has reported the…

Electrophoresis is integral to analytical and biochemistry experiences in undergraduate education; however, fundamental principles of the method are often taught in upper-level laboratories through hands-on experiences. A laboratory activity is reported that teaches the concepts of electrophoretic mobility and electroosmotic flow. A single…
