Liquid metals are widely applied in various fields, including chemistry, catalysis, energy storage, chemical sensing, and stretchable electronics, due to their unique deformabilities. However, their behavior under a rod or ring electrode has never been analyzed. Furthermore, research on the deformation behavior of eutectic Ga--In (EGaIn), the most…

A novel teaching approach is aimed at elucidating the concept of bond enthalpy for general chemistry students. Through the integration of a hands-on candy pulling activity, students in a large lecture class were provided a tangible experience to explore bond strengths using rope candy and a luggage scale. Feedback from students indicated a clear…

Socio-scientific issues-based science instruction addresses societal-related issues to promote contemporary science education. Societal-related issues almost always have to be considered in the cultural environment to which they are relevant. This means that the cultural aspects of socio-scientific issues need to be taken into account to develop…

Synthesis of (Z)-alkenes is challenging because the (E) stereoisomers are usually more stable. Energy transfer photocatalysis has emerged as an efficient strategy for (E) [right arrow] (Z) alkene isomerization. We report the development of an advanced undergraduate laboratory experiment that introduces students to contemporary organic…

Herein we describe an accessible and safe at-home experiment to separate lycopene from tomatoes via liquid-liquid extraction. As a qualitative experiment, it is a canonically elementary instance for high school students to digest the conception of miscibility, immiscibility, and density difference of the two solvents. This experiment was performed…

The activity proposed in this study aims to investigate the equilibrium between the liquid and vapor phases in a mixture of water and acetic acid, both of which are volatile substances. High school students can easily determine the composition of the liquid phase and its corresponding vapor phase at equilibrium using a simple and conceptually…

We are all users of lithium-ion batteries (LIBs), the electrochemical energy storage devices that revolutionized our life, making the diffusion of portable and wearable devices possible and now driving the switch from a combustion engine to electric vehicles in the transportation sector. These positive trends are however leading to two whiplash…

Though job opportunities in science, technology, engineering, and math (STEM) continue to expand in the United States, people on Individualized Education Programs (IEPs) while in school are continually disadvantaged in future STEM-based career possibilities. Studies have shown that students on IEPs are far less likely to major in a STEM degree…

Artificial intelligence (AI) and data science (DS) are receiving a lot of attention in various fields. In the educational field, the need for education utilizing AI and DS is also being emerged. In this context, we have created an AI/DS integrating program that generates a compound classification/regression model using characteristics of compounds…

Aqueous solutions have proved to be a challenging topic for chemistry students at all levels. An understanding of what is happening at the molecular level in aqueous processes such as dissolution is key to understanding the macroscopic properties of the system as well as to communicating fluently with chemical symbols. In this study, we examined…

A traditional laboratory course with the primary learning outcome of improving students' theoretical knowledge has received much criticism over the years due to the lack of evidence that these goals have achieved. We report our efforts to redesign a traditional first-year organic and inorganic (also known as synthetic) laboratory course from…

The effects of kinetic vs thermodynamic control on "endo"/"exo" stereoisomer ratios can be observed in a simple Diels-Alder reaction between "N"-phenylmaleimide and furan. The use of microwave-promoted synthesis affords the cycloadducts in yields ranging from 65-100%, employing reaction times of 1-10 min at…

A parallel series of general chemistry courses for Life Science Majors was created in an effort to support students and improve general chemistry outcomes. We created a two-quarter enhanced general chemistry course series that is not remedial, but instead implements several evidence-based teaching practices including Process Oriented Guided…

SSurfactants or surface-active agents are interesting groups of compounds with characteristic structures, allowing them to decrease the surface tension. A surfactant consists of a hydrophilic head and a hydrophobic tail. Typically, surfactant molecules aggregate into micelles at the critical micelle concentration. In this work, the concept of…

Approximations can help to orient the student in an organic chemistry laboratory. There the student needs to develop the solvent systems for the reaction and isolation of organic reactants and products. The adage "like dissolves like" helps in this regard, but this approach is vague and entirely qualitative. More quantitative approaches…
