Since PAH is improved by HO-1 induction [33,34], PETN
is a potential candidate drug for treatment of this severe disease, currently investigated within the CAESAR clinical trial ("ClinicAl Efficacy Study of Pentalong[R] for PulmonAry Hypertension in HeaRt Failure"; EudraCT Number: 2009-015059-26).
The effect of the source-detector-target angle on the IR spectra of PETN
overlain on RDX was used to obtain the required thickness.
They also found 9.8 grammes of PETN
, a powerful secondary explosive which if detonated by itself could cause serious, if not fatal injuries, but would not be subject to spontaneous combustion.
In an earlier study by the authors , detection and discrimination of explosives such as PETN
, TNT, and RDX were demonstrated using tape-cast ceramic mixed potential sensors based on a zirconia solid electrolyte.
Entre los explosivos mas energeticos esta el tetranitrato depentaeritritol (PETN
), el cual se sintetiza mediante la nitrificacion de derivados de alcoholes formando enlaces ester de dificil degradacion (White et al.
was used by the "underpants bomber" Umar Abdulmutallab when he tried to blow up a plane on Christmas Day, 2009.
Summary: TEHRAN (FNA)- Scientists have developed an extremely sensitive explosives sensor that is capable of detecting even slight traces of the high-explosive chemical compound pentaerythritol tetranitrate (PETN
Such a pouch would blend in with the scanned body in the image created by the scanner and "be easily confused with normal anatomy." The authors of the study note that if a dangerous amount of the high-explosive PETN
powder were affixed to the body in this way, it would be easily detected in a traditional pat-down, thanks to its bulk.
The hidden bomb, a printer cartridge packed with the explosive PETN
attached to a concealed mobile SIM card, was posted via freight firm FedEx, and the second device - which was posted via UPS in Yemen - was also found at East Midlands Airport in the UK.
The editors' boast that they chose printer cartridges in which to hide the explosive because toner is carbon-based, with a molecular composition "close to that of PETN
," so it would not be detected.
Experts in Germany said the bomb, and another found in Dubai, contained at least 300g (10.58oz) of the powerful explosive PETN
. It had travelled through a UPS hub at Germany's Cologne airport before being detected in the UK following the tip-off, officials said.
