Allotropes matter: A backbone breaking Carbon discovery

A recent discovery of a new carbon allotrope (E Meirzadeh, et al., 2023) has shaken the scientific community. It will have potential implications for the folks dabbling in the quantum computing realm 🖥️. But first, we have to be reminded more then we are taught: Allotropes are different forms of the same chemical element with differingContinue reading “Allotropes matter: A backbone breaking Carbon discovery”

Perflubron Liquid breathing: Is it time to blow off air?

In second year of undergraduate, we walked into what we thought would be a standard anatomy class. But what we didn’t expect to see were to pairs of lungs open on the bench. One infant size. The other much larger. Much darker. The pearly white of the infants lung contrasted with the polluted adults lung.Continue reading “Perflubron Liquid breathing: Is it time to blow off air?”

Gibbs free energy is foundational for HSC chemistry

The universe is ever growing into more and more chaos. This is a law of thermodynamics. Gibbs free energy is able to tell us whether a reaction will occur. The three factors which influence this are whether the reaction creates chaos, whether heat will be released and what the temperature is. Learn. Gibbs free energyContinue reading “Gibbs free energy is foundational for HSC chemistry”
