Bishi Bashi + Harbour Town-ed + Cheesecake

Went to the city on Friday, being coop up in St Lucia kampung isnt too healthy, suddenly large crowds scare me!!! Like where did all these ppl came from? hurhurhur. Will be back to normal in Singapore, since the Sg's toowong equivalent, WESTMALL is so friggin crowded every single day. Had dinner at Pancake Manors, Mexicana crepe and Macadamia nut pancake which was super good!!! tested my Bishi-bashi skills, sad to say, i lost the magical bashibashi touch alr! OH NOS!!

Harbour Town on Saturday!!!
YAAAAAAAAY!!! Lotsa DFO, so presumably, lotsa great bargains and shopping? Not for me though?! Only got 1 FCUK tee, and... thats about it?! Wanted to get a Adidas jacket at $50, but i wanted to get the UQ jacket more... and its quite ridiculous to buy both, so gave up the Adidas one. the $59 polo ralph lauren doesnt interest me either. huh. and all the levis is like high waist which is quite dortsie... luckily, managed to have a somewhat good lunch there to justify the trip.
PS: i bought the UQ jacket alr...

Cheesecake sunday
Baked a Lemon-Lime cheesecake on Sunday. Kinda failed.
1) biscuit crumbs too fine, no crunchy bits
2) added too much liquid => soggy
3) forgot to bake the crust first, resulting in super soggy cheesecake base
4) fogot to add eggs while beating the cream cheese, no idea whats the implication, prolly not fluffy?
5) pan kinda too big, resulting in super thin cake...
at least the taste is still alright... shall bring it to the lab and HOPE that they wont mind a baseless cheesecake.

Monday - Peptide day!
coupled the last amino acid and azide... hopefully the unbrowness is not a cause for concern!
DONE WITH PEPTIDE SYNTHESIS. YAY!!!

*pics to be uploaded tml. kinda sleepy alr. *

work hazards!!!

OMG. i just checked some chemical webby and this was what i saw...

" Dimethylformamide is the organic compound with the formula (CH3)2NC(O)H. Commonly abbreviated DMF, this colourless liquid is miscible with water and the majority of organic liquids. DMF is a common solvent for chemical reactions.

DMF has been linked to cancer in humans, and it is thought to cause birth defects. In some sectors of industry women are banned from working with DMF. For many reactions, it can be replaced with dimethyl sulfoxide. Most manufacturers of DMF list (Life) or (Chronic) as a health hazard in their MSDS since DMF is not readily disposed of by the body. According to IARC, DMF is a possible carcinogen. "

yup! And i use it like water in the lab... i think i'm gonna get thumb cancer cos my right thumb is extremely wrinkled noww. =|


and then i used this too, though lessss frequently...

" Dichloromethane (DCM) or methylene chloride is the chemical compound with the formula CH2Cl2. It is a colorless, volatile liquid with a moderately sweet aroma. It is widely used as a solvent, the general view being that it is one of the less harmful of the chlorocarbons.

Dichloromethane is the least toxic of the simple chlorohydrocarbons, but it is not without its health risks as its high volatility makes it an acute inhalation hazard. Dichloromethane is also metabolised by the body to carbon monoxide potentially leading to carbon monoxide poisoning. Prolonged skin contact can result in the dichloromethane dissolving some of the fatty tissues in skin, resulting in skin irritation or chemical burns.It causes cold burns. "

Dont know about others but it certainly doesnt have a moderately sweet aroma.


and this...

" Acetone is a colorless, mobile, flammable liquid. It is the simplest example of the ketones. Acetone is miscible with water, ethanol, ether, etc., and itself serves as an important solvent.

The most common hazard associated with acetone is its extreme flammability. Acetone is an irritant and inhalation may lead to hepatotoxic effects (causing liver damage). The vapors should be avoided. In no circumstance should it be consumed directly or indirectly. Always use goggles when handling acetone; it can cause permanent eye damage (corneal clouding). "

ohhh, and i recall the times where i wash the vials without wearing googles, drying them with acetone. Have seen the clouding thing before, tried cleaning my cuvette and it become clouded..hah... permanently too.
