Influence of the thickness absorbing film on the PETN ignition threshold by a laser pulse [PDF]

MATEC Web of Conferences, 2015
Numerical simulation of the PETN ignition by a film, which is heated by a laser pulse was conducted. There are shown that dependence of threshold energy of ignition of PETN by a laser pulse has a linear dependence from the thicknesses of the absorbing ...

Initial Response of Pentaerythritol Tetranitrate (PETN) under the Coupling Effect of Preheating, Shock and Defect via the Molecular Dynamics Simulations with the Multiscale Shock Technique Method

Molecules, 2023
The initial response of PETN under the coupling of preheating, impact and defects was simulated by Multiscale Shock Technique (MSST) method and molecular dynamics. The temperature change of PETN during impact compression can be divided into three stages:

Explanation of the Colossal Detonation Sensitivity of Silicon Pentaerythritol Tetranitrate (Si-PETN) Explosive [PDF]

Journal of the American Chemical Society, 2009
DFT calculations have identified the novel rearrangement shown here for decomposition of the Si derivative of the PETN explosive [pentaerythritol tetranitrate (PETN), C(CH_2ONO_2)_4] that explains the very dramatic increase in sensitivity observed ...

Pentaerithrityl tetranitrate (PETN) for prevention of fetal growth restriction in pregnancy: A systematic review and meta-analysis [PDF]

European Journal of Obstetrics & Gynecology and Reproductive Biology: X
Background: Fetal Growth Restriction (FGR), often due to placental insufficiency, poses significant risks to perinatal outcomes. This review evaluates the efficacy of pentaerythritol tetranitrate (PETN), a nitric oxide donor, in preventing FGR.

PETN-Induced Antioxidative Properties in Endothelial Cells as a Target for Secondary Prevention of Endothelial Dysfunction in Pregnancy

Frontiers in Physiology, 2022
The NO-donor Pentaerytrithyltetranitrate (PETN) has vasodilatative properties and direct protective effects on endothelial cells. We formerly demonstrated that PETN, given to pregnant women during the second and third trimester, influences endothelial ...

The nitric oxide donor pentaerythritol tetranitrate reduces platelet activation in congestive heart failure. [PDF]

PLoS ONE, 2015
Platelet activation associated with endothelial dysfunction and impaired endogenous platelet inhibition is part of the cardiovascular phenotype of congestive heart failure (CHF) and contributes to the increased risk for thromboembolic complications ...
