Flipped and Free: an inverted, active-learning general chemistry course using exclusively OER

Presentation on using a flipped course format and including an open textbook, OpenStax: Chemistry 2e. Flipped courses provide lecture content that is accessible online, and they use class time for active learning activities. It is a part of 2022 University of North Texas Open Access Symposium that was held on March 8, 2022.

Comments on “Thermodynamic modeling studies of aqueous solubility of caffeine, gallic acid and their cocrystal in the temperature range of 303 Ke363 K” (open access)

Comments on “Thermodynamic modeling studies of aqueous solubility of caffeine, gallic acid and their cocrystal in the temperature range of 303 Ke363 K”

This article comments on activity coefficients based on a thermodynamic relationship that failed to properly take into account the solid phase transition that both caffeine and gallic acid exhibited prior to melting.

A theoretical study of M–M′ polar-covalent bonding in heterobimetallic multinuclear organometallic complexes of monovalent group 11 metal centres (open access)

A theoretical study of M–M′ polar-covalent bonding in heterobimetallic multinuclear organometallic complexes of monovalent group 11 metal centres

Article describes how complexes with closed-shell (d10–d10) interactions have been studied for their interesting luminescence properties in organic light-emitting diode (OLED) devices. The present computational study aims at understanding the chemical bonding/interactions in a series of molecules with unusually short metal–metal bond distances between monovalent coinage-metal (d10–d10) centres.

Solvation Descriptors for Zwitterionic α-Aminoacids; Estimation of Water–Solvent Partition Coefficients, Solubilities, and Hydrogen-Bond Acidity and Hydrogen-Bond Basicity (open access)

Solvation Descriptors for Zwitterionic α-Aminoacids; Estimation of Water–Solvent Partition Coefficients, Solubilities, and Hydrogen-Bond Acidity and Hydrogen-Bond Basicity

This article uses the literature data on solubilities and water–solvent partition coefficients to obtain properties or “Absolv descriptors” for zwitterionic α-aminoacids: glycine, α-alanine (α-aminopropanoic acid), α-aminobutanoic acid, norvaline (α-aminopentanoic acid), norleucine (α-aminohexanoic acid), valine (α-amino-3-methylbutanoic acid), leucine (α-amino-4-methylpentanoic acid), and α-phenylalanine.

Reference materials for phase equilibrium studies. 1. Liquid–liquid equilibria (IUPAC Technical Report) (open access)

Reference materials for phase equilibrium studies. 1. Liquid–liquid equilibria (IUPAC Technical Report)

This article is the first of three projected IUPAC Technical Reports resulting from IUPAC Project 2011-037-2-100 (Reference Materials for Phase Equilibrium Studies). This report proposes seven systems for liquid–liquid equilibrium studies, covering the four most common categories of binary mixtures: aqueous systems of moderate solubility, non-aqueous systems, systems with low solubility, and systems with ionic liquids.

AFLOW-QHA3P: Robust and automated method to compute thermodynamic properties of solids (open access)

AFLOW-QHA3P: Robust and automated method to compute thermodynamic properties of solids

Article introducing the quasiharmonic approximation three-phonon method to calculate the thermodynamic properties of both nonmetallic and metallic compounds. This study demonstrates that QHA3P is an ideal framework for the high-throughput prediction of finite-temperature material properties, combining the accuracy of QHA with the computational efficiency of SC-QHA.
