The sensor reaction mechanism was verified by various experimental characterizations, including chromatography, UV-Vis absorption and fluorescence spectroscopy, MS and (1)H NMR spectrometry. When fabricated within silica gel TLC plate, the fluo-spot sensor features high sensitivity owing to the large surface area and porous structure of the substrate.
Trace Detection of RDX, HMX and PETN Explosives Using a Fluorescence Spot Sensor. The DCM sensor can also be used as an economical spray kit to directly spot the explosives by naked eyes, implying great potential for quick, low-cost trace explosives detection. The fluo-spot also demonstrated high selectivity towards RDX, HMX and PETN, as no significant fluorescence quenching was observed for other chemical compounds including common nitro-aromatic explosives and inorganic oxidative compounds. The sensor reaction mechanism was verified by various experimental characterizations, including chromatography, UV-Vis absorption and fluorescence spectroscopy, MS and 1H NMR spectrometry. (or NO2+) generated from the UV photolysis of RDX, HMX (or PETN).The sensor molecule is a charge-transfer fluorophore, DCM, which is strongly fluorescent in its pristine state, but non-fluorescent after the quick reaction with NO2Â
Here we present a fluo-spot approach, which can be employed for in situ detection of trace amount of explosives. A quick, sensitive, and low-cost detection method for these non-volatile explosives is eagerly demanded. Wu, Na Xu, Miao Yang, Xiaomei Yu, Li Zang, Lingġ,3,5-trinitroperhydro-1,3,5-triazine (RDX), octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), and pentaerythritol tetranitrate (PETN), the major components in plastic explosives, pose a significant threat to public safety. Wang, Chen Huang, Helin Bunes, Benjamin R. This should be resolved sometime early next year and be official.Trace Detection of RDX, HMX and PETN Explosives Using a Fluorescence Spot Sensor But once this problem is overcome, there is rumours that Tomy will be getting Takara sculptors to work for them - which should further boost the detail in their products! So we just have to sit and wait. Tomy have had a few issues recently, thus they have been announcing and then cancelling their stuff. The Zoids Girls one is a new set that is 'unofficially' going to be released by Tomy. They were produced as completed pre-painted figures on display cards. They dont not often pop up on ebay, but I can take a photo of my friend's set.
There is a Reese, Moonbay, Fiona, Naomi, Leena, and the more recent release would be the Tasker Sisters and Kanon. Thus you will probably not find them that easily. You people have been confused by two TOTALLY different things! The SR DX figures are actually individually packed (NOT RANDOM) figures which were released quite some time ago and have been discontinued already.
