    Buckyballs surface chemistry

    I've got a project I'm interested in. Essentially its modifying a melamine foam so its thermal conductivity is at least halved. Was thinking some type of buckyball filler in the matrix might be a ticket. However someone pointed out it maybe a worry about how it would affect the cell...

    What would the products of photolysis degredation of PET plastic be?

    Interested in this because plastic drinking bottles have a taint to them when left out in the sun. I gather its from UV degredation of the PET plastic. I'd like to find a catalyst that would allow the PET byproducts to be non water soluble/sequester or even evaporate.

    Looking for a specific dye

    Hi folks, I'm looking for a dye that absorbs strongly around the 490nm range. Sort of a red/orange I guess. I cannot find a lot of data on absorbency by dye manufacturers, will begin emailing them shortly. Key word searches tend to bring up dye absorbency in relation to materials not light...

    How would I find a UV-VIS spectra of human urine?

    found something useful, for me at least. 450nm. Where Bilirubin absorbancy peaks. Bilirubin giving urine its hue.

    How would I find a UV-VIS spectra of human urine?

    That is my plan B. But a spectrophotometer costs 125NZD/hour :(

    How would I find a UV-VIS spectra of human urine?

    Preferably I would like to find a UV-VIS absorbance spectra of urine. I have found ones that focus on the deep UV range, and one that had fluorescence peak information. Any help would be appreciated.
