ChemiSTEAM 2021: A Journey to Pure Hexagonal Crystals

CHEMISTEAM

“A Journey to Pure Hexagonal Crystals” received an honourable mention at ChemiSTEAM 2021. Every time that I show this type of picture to lab mates and friends they are intrigued by the shape of the crystals. It leads to a conversation about crystals that can be visualized at the macro or microscopic level. It’s fascinating...

ChemiSTEAM 2020: They grow up so fast

CELEBRATE

When my ChemiSTEAM submission entitled ‘They grow up so fast!’ received an honorable mention and I was asked to write a short piece about it, I knew I was going to have to explain why the title relates to children. I became obsessed with crystals and crystallography during my undergraduate chemistry degree at Memorial University....

ChemiSTEAM 2020: Sublimation of VO(acac)2

CELEBRATE

In this synthesis, we attempted a sublimation of our crude product as an alternative to the usual purification of vanadyl acetylacetonate that involves the recrystallization from dichloromethane and ether. This was a conscious effort to change the synthesis towards methodology that incorporated principles of green chemistry. By making this switch, we tried to make a safer and more efficient synthesis that avoided using dangerous solvents and reduced the waste. I captured this close-up of the sublimed crystals in their vibrant blue and chaotic crystalline texture that showcases this attempt.
