VSEPR Theory and Molecular Geometry
Valence Shell Electron Pair Repulsion (VSEPR) theory coupled with Lewis electron configurations, which identifies lone pair electrons, provides an effective way to predict the molecular geometry, or shape, and bond hybridization of a molecule around a central atom.

The Laws of Thermodynamics, Entropy, and Gibbs Free Energy
Enthalpy, entropy, and the Gibbs Free Energy are measures of the energy, energy distribution and spontaneity of a system respectively. Professor Dave explains each with an analogy and an example. He also shows how systems can spontaneously transition to lower entropy.
Jan 09, 2016
Valence Bond Theory, Hybrid Orbitals, and Molecular Orbital Theory
Hybrid bonds occur when atoms bond with electrons from two different orbitals. Professor Dave presents several examples.
Sep 03, 2018
Lattice Structures in Ionic Solids
Professor Dave uses an animated three dimensional graphics program displaying several molecules to show how their molecular shapes effect the geometry of their crystal lattice.
Dec 27, 2018
Pseudo Noble Gas Electron Configurations
Pseudo Noble Gas Electron Configurations result when transition metals ionize by shedding one or two electrons from their highest s orbital leaving their highest d orbital complete.
Jan 07, 2019
Complex Ion Formation
Professor Dave explains the solvation process when salts dissolve in a liquid. Solvent molecules cluster around the a central metal ion forming a molecular complex ion with solvent molecules as ligands. Dave also displays typical chemical equations for the solvation reaction and explains how to balance the equations.

Coordination Compounds: Geometry and Nomenclature
Here is Professor Dave's introduction to coordination compounds. These are compounds in which a ligand forms a covalent bond with a central metal atom. He provides several examples to explain the electron configuration, shape, number of ligands and ligand types. Then it's time to name them.
Jul 25, 2019
Crystal Field Theory
Professor Dave explains that the "crystal field splitting energy" effects how metal orbitals are filled by the various ligands in the spectrochemical series. Depending on which orbitals are filled first Crystal Field Theory predicts the structure, color and magnetic characteristics of coordination compounds.

Organocuprates (Gilman Reagents)
Organocuprates are less reactive than organolithium and Grignard reagents making them suitable for beta addition to carbonyls.

The Alpha Centauri System
If your interested in taking a trip to another star your closest option is a rocky planet around Proxima Centari. It is the only confirmed planet in the closest star system to Earth. But the star isn't exactly stable and the planet is in a close orbit so it may be tidally locked so you have a choice of the sweltering side of the freezing side of the planet. Even if you like this destination you're in for a long trip as it is over four light years away.

Types of Immune Cell Receptors
Our immune systems contains a variety of immune cell receptors. Some are specific to individual antigens. Other are general purpose pattern recognizing receptors. Here's an inventory with a description of what each receptor detects and what it does.

Vilsmeier Reaction
The Vilsmeier Reagent is produced by the action of various chlorophosphorus compounds on Dimethylformamide. The reagent is an electrophile that readily ads to double bonds. When followed by hydrolysis the result is the addition of an aldehyde group known as formylation.

Metallic Bonds
We naturally perceive metals as different from other materials. In metals the electrons are delocalized. This delocalization gives metals the special properties we observe and results in something of a hybrid bond that has properties between those of ionic and covalent bonds.

Introduction to Inorganic and Organometallic Chemistry
This is an overview of plans for a series on inorganic and organometallic chemistry beginning with a group by group survey of the period table.

The 8 Classes of Minerals Part 1: Native Elements, Oxides, Halides, and Sulfides
Professor Dave explains minerals from the perspective of chemistry.

The Definitive Guide to Debunking Creationists Part 1: Cosmology/Planetary Science
This conversation begins by describing the spectrum beliefs about the rolls of God and physics in creating and controlling the universe which are essential to understand before joining the debate. An explanation of how science addresses Creationist questions follows.

Occupied City

Occupied City

The past collides with the present in this excavation of the Nazi occupation of Amsterdam: a journey from World War II to recent years of pandemic and protest and a provocative, life-affirming reflection on memory, time and what's to come.

Cries from Syria

Cries from Syria

CRIES FROM SYRIA is a searing, comprehensive account of a brutal five-year conflict from the inside out, drawing on hundreds of hours of war footage from Syrian activists and citizen journalists, as well as testimony from child protesters, leaders of the revolution, human rights defenders, ordinary citizens, and high-ranking army generals who defected from the government. Their collective stories are a cry for attention and help from a world that little understands their reality or agrees on what to do about it. A documentary by Evgeny Afineevsky, director of the Oscar-nominated film WINTER ON FIRE, CRIES FROM SYRIA premiered at the 2017 Sundance Film Festival.
