The cover picture shows a pentaerythritol tetracarbamate (PETNC) molecule, a new high explosive, which has a positive oxygen balance, is stable up to 196 °C and could be initiated with a standard detonator. PETNC is much less sensitive than pentaerythritol tetranitrate (PETN) or nitroglycerin but once detonated delivers the same lethal energy to the target. Moreover, due to its positive oxygen balance, it can also be used as a “green” oxidizer in pyrotechnical formulations. Details are discussed in the article by Thomas M. Klapötke et al. on 723 ff.
