Today was a campus-wide orientation (Imagine Day) for new undergraduate students at UBC. Alongside orientation are a bunch of free things to collect, including this mug that changes to a blue colour upon cooling down (see left to right)!

Bless UBC Science.

Also, the head of the Department of Chemistry and one of the professors did the ALS Ice Bucket Challenge with reaaaaally cold water (i.e. cooling it down with liquid nitrogen). It was pretty cool (pun intended).

Nothing like holding a pure compound that you have just synthesized.
(bottom picture shows the structure of the synthesized compound)

The last steps in the synthesis involves hydrolysing the ester bond on the naphthalene ring and then coupling the carboxylic acid to a dipeptide chain.

These molecules are being synthesized and studied due to their anti-cancer activity shown in both lung cancer and malignant melanoma cell lines. Although past research is all ‘in vitro’, we hope to push for ‘in vivo' testing in the future.

The intense blue color of a freshly prepared copper(II)-amine complex. 
Did you know that only the copper(II) amine complex has a blue color? If elemental copper is added to an e.g.: tetraamminecopper(II) chloride ([Cu(NH3)4]Cl2) solution and it is heated, the intense blue color will fade and a colorless or white powder will precipitate, the copper(I) complex. What happens? The copper(II) is reduced by elemental (0) copper to give the +1 oxidation state metal. Cu(+2) + Cu(0) = 2 Cu(+1)
