Calculating Societal Cost for Gas your vehicle emit
Thursday, March 15th, 2007I found this very interesting to find out, how to quantify potential loss, societal cost due to gas emission from our transportation. Let's do the math now!

Planning ahead: theses
Wednesday, March 14th, 2007Right, I am trying to list here what I am planning to do within short time: At the moment, I am cleaning my all membranes after TiO2-UV batch: 1 kD, 15 and 50 kD, two pieces for each.
TiO2 coating procedures
Tuesday, March 13th, 2007There are various methods available to coat TiO2 onto the surface of the membrane. I will explain briefly some of them, and the method I used. Ion assisted deposition This method was used for coating on super-hydrophobic porous teflon membrane. The author stated that the coating of TiO2 by the chemical wet ...
Water treatment: impure water, back to history
Sunday, March 11th, 2007Impure water is a water that contaminated by unwanted elements. It can be particles, colloids, debris. Of course, for both drinking water or clean water for household activities, these impurities are not wanted. Thus, it is important for us to treat source water to remove these elements. That is why ...
TiO2-UV batch for UF fractionation
Saturday, March 10th, 2007The result of my experiment employing TiO2-UV was not satisfying. In terms of flux, TiO2-UV membrane showed severe decline after 30, 60, and around 90 minutes. Not only that, the rejection of membrane coated by TiO2 under UV exposure was lower than naked membrane. This probably due to smaller ...
