Day 3!

Our day began with a quick lunch at Canteen 1 near the Hall of Residence, where some fellow researchers and students stay! After that, we continued touring around the campus to the Sports & Recreation Centre, where the facilities there serve as an avenue for the students to have fun and relax~

From there, we made our way to the Nanyang House, where we had a fun game of pool~

*Focused on the game*

After a few games, we visited the ADM (School of Arts, Design and Media), where its exterior made the whole building stand out~

ADM!

SMILE~

 When the rain came, we made our way back to MSE to resume the Contact Angle experiment. First, we stopped by the Heat Treatment Lab to collect samples of Graphene Oxide chips which we left in the oven on Monday.

GO chips in oven~

All ready for experiment~

We resumed the experiment back at the lab with the Contact Angle Measurement Machine.

The reason why we had to redo the experiment was because the results obtained on Day 1 was not within the expectation. Also, more readings means better average readings, thus more accurate results~

We also had the honour of carrying out the experiment on our own!

Let's begin~

Step 1: Place GO chip under syringe~ 

Step 2: Select "Pump Out" to release water~

Slowly~ 1 drop is enough~

 

Controlling the output of water~

 The rate at which water is released. 1.8 microlitres/s~

Step 3: After 1 drop, select "Pump In"~

This prevents any more water to be pumped out.

Step 3*: Once water is fully pumped in, deselect "Pump In"~

Step 4: Take a snapshot of the current image~

Step 5A: Select "Contact Angle" to have the computer automatically measure the contact angle~

Step 5B: Select "Zoom" to manually select points to calculate the contact angle~

Opps! There's an error~

Incorrect(Left)/Accurate(Right)

After all the experimentation, we finished the day off with a tour around more labs, where we found some quite interesting equipment, and work places~ 

Samples after samples after samples~

And even more samples~

With this amount of samples, experimentation is going to take awhile~

 An ultrasonicator used for cleaning~

 

 An evaporator~

A Glove Box~ CAREFUL OF THE EXPLOSIVE SUBSTANCE INSIDE!

Today couldn't have been any better, a day of work and play~
Tomorrow, we'll be attending the UK-Singapore Materials Workshop 2012 “Materials for Tomorrow” at The Matrix, Biopolis.

STAY TUNED FOR MORE UPDATES AND PHOTOS OF TOMORROW~
