And so we finished our proposal + presentation...

yay!
finally can take a rest.
Thanks for all your work!

Just a glimse at the crystals I grown..

Didn't have time to write comments. Just take a peek at those beakers.

Here's some photos of them.

NiSO4 crystals grown on microslide. Nice rod shape crystal formed with branches.

CuSO4 crystals grown on microslide. The usual rhombic shape.

NiSO4 crystals and CuSO4 crystals grown on glass capillary tube.
NiSO4 crystals tend to grow around the capillary tube, while the CuSO4 crystal grow on one end of the tube.

NiSO4 crystals grown on polypropylene rod

CuSO4 crystals grown but not on the PP rod

NiSO4 crystals grown but not on the surface of steel epoxy resin

CuSO4 crystals grown but not on steel epoxy resin

update

most of the parts are finished. yay!

And someone told me that he / she cannot comment here. I've checked the settings and please try again. This time it should work. Thanks.

Progress so far..

I've finally finished my part (Network diagram / Gantt chart / WBS / combining all our group work together into a single file). But still some parts are missing. The files have been emailed to you guys and gals already.

My body is still crying in pain and so I am going to take some sleep now. Considering taking a sick leave tomorrow. Too tired.

miss the old times..

Missing the old times (okay, a few years ago to be exact) that we're still using MS office 2000.
Just found out that the new one (MS office 2010) sucks.

(為了畫WBS同network diagram同gantt chart而暴走中.......)

progresses so far...

On 16/3/12 I have prepared three beakers with different solutions and substratum.

First, the beakers were cleaned and the saturated solutions of nickel (II) sulphate (NiSO4) and copper (II) sulphate (CuSO4) are prepared.
Then fishing lines were cut and weighed and put into the different solutions as substratum.

The first beaker is NiSO4 with fishing line immersed.
The second beaker is CuSO4 with fishing line immersed.
The third beaker is CuSO4 with fishing line immersed.

The beakers were put at a corner in Chemistry lab and wait.


Then on 19/3/12, the beakers were taken out for observation.
For the first beaker (NiSO4 with fishing line), crystals grow on the surface of the substratum.

For the second beaker (supersaturated CuSO4 with fishing line), crystals grow at the bottom of the beaker and not on the surface of substratum.

For the third beaker (CuSO4 with fishing line), no crystals was grown on the surface of the substratum so far.

Next, 8 different beakers of solutions were prepared (4 of them were NiSO4 and 4 of them were CuSO4), and different substratum were added to the solution.
The substratum added were:
- glass microscopic slide (cut into small pieces)
- glass capillary tube & glass ball (dia. 2.5 - 3mm)
- plastic rod
- steel epoxy (rolled into rod shape and left dry)
The substratum were weighed and put into one set of solutions (1 beaker of NiSO4 and 1 beaker of CuSO4).
The beakers were again put at a corner in lab and wait.

communication is king!

Just started this blog mainly for our project.
We can share photos and progress here.

Let's start then.
