Does anyone knows why does a MRT station needs the gas bromo-trifluoromethane? I found that every MTR (MRT in HK is known as MTR) station in HK contains this gas.

I've checked with 赵宇 (Frankie's room mate from 北京) and he told me that 溴 means bromine, 氟 means chlorine and the last 3 words mean methane. Piecing up the words it means "bromo-trifluoromethane". The worst thing is, it's toxic! o_O

I'm not feeling well as I'm down with a pretty bad flu; was sneezing and coughing for the whole of last night and today. Nonetheless, I still went for the Chemistry seminar at HK Baptist University this morning at 1130. The presentation is pretty interesting; it's about using camphor as chiral auxillaries in asymmetric synthesis. The prof. is from Taiwan National Tsing Hua University and he's the expert in this area in this region. His synthetic routes and proposed mechanisms were elegant and I enjoyed the presentation. The only drawback is that I am sick and so can't really concentrate. Sigh.

Anyway the long weekend that has just past was pretty adventurous. Sat and Sun, I went to 深圳 together with 书成, 赵宇, Yuin Yee and Daniel. Sat was mainly shopping at 东门 and we had dinner at 书成's place. We stayed over at his place before going for book hunt and 世界之窗 the next day.

The catch phrase for 世界之窗: "您给我一天，我给您一个世界!". Hmm 世界之窗 has been rather disappointing as it's not as real as I expected it to be. The picture painted by the web and media appeared too rosy.

Mon, I went to find Teck Loon as he came over to Macau and HK for a short tour. We had dim sum and spent some time walking along Nathan Road and 尖沙咀 area.

Ahh, sneezing again; better go and catch some sleep. zzz...
