Nanoparticle synthesis is an important area of nanotechnology and has been performed by undergraduate students from various universities across the globe. Due to the availability of massive data on the synthesis of a wide variety of metallic nanoparticles, including silver, gold, selenium, zinc, copper, iron, palladium, platinum, titanium, etc.,…

A simple bioassay was designed for the detection of adenosine, a human metabolite involved in several physiological processes, on the basis of the functionalization of gold nanoparticles with DNA oligonucleotides selectively binding adenosine. The test was possible thanks to the selective and sensitive binding of adenosine by two DNA…

Preceding even the Hartree-Fock method, molecular integrals are the very foundation upon which quantum chemical molecular modeling depends. Discussions of molecular integrals are normally found only in advanced and technical texts or articles. The objective of the present article is to provide less experienced readers, or students in a…

In this organic chemistry laboratory experiment, students are guided through a series of exercises to understand the behavior of compounds during liquid-liquid extraction. Aspects of density, structure, solubility, acid-base theory, and pK[subscript a] are all incorporated into activities that students complete in groups. After using their initial…

Reported herein is a multidisciplinary laboratory experiment for advanced undergraduate students that includes elements of material synthesis, in the synthesis of cyclodextrin-containing metal-organic frameworks (CD-MOFs), and environmental chemistry, in the use of these MOFs for pollutant removal. This multiday laboratory experiment starts with…

Many students find the transition from first-year general chemistry to second-year organic chemistry a daunting task. There are many reasons for this, not the least of which is their lack of a solid understanding and appreciation of the importance of some basic concepts and principles from general chemistry that play an extremely critical role in…

Presented is an introduction to the interpretation of electron spin resonance spectra of organic radicals. The article is written for undergraduate college students. (RH)

Introduced is a method for estimating carbon-13 nuclear magnetic resonance (NMR) shifts. The method is brief and simple so that students can use it with ease. (RH)
