Advances in science and technology of modern energetic materials: an overview.

Energetic salts offer many advantages over conventional energetic molecular compounds. The use of nitrogen containing anions and cations contributes to high heats of formations and high densities. Their low carbon and hydrogen content gives rise to a good oxygen balance. The decomposition of these compounds is predominantly through the generation of dinitrogen which makes them very promising candidates for highly energetic materials for industrial or military applications.

Energetic nitrogen-rich salts and ionic liquids.

In agreement with the current trend of giving value to natural and renewable resources, the use of natural antimicrobial compounds, particularly in food and biomedical applications, becomes very frequent. The direct addition of natural compounds to food is the most common method of application, even if numerous efforts have been made to find alternative solutions to the aim of avoiding undesirable inactivation. Dipping, spraying and coating treatment of food with active solutions are currently applied to product prior to packaging as valid options. The aim of the current work is to give an overview on the use of natural compounds in food sector. In particular, the review will gather numerous case-studies of meat, fish, dairy products, minimally processed fruit and vegetables and cereal-based products where these compounds found application.

Applications of nano-catalyst in new era

New approximate formula for Arrhenius temperature integral

Ring-substituted arylammonium perchlorates have been prepared and characterized gravimetrically. Thermal and explosive characteristics or these salts are studied by TG and explosion delay measurements. The explosion temperatures (ET), energies or activation for decomposition (E d ), and explosion (E * ) were round to be linearly related with pK a values or the corresponding arylamines. Further, these parameters have also been round to be related with Hammett substituent constant (a). The proton-transfer process seems to be the primary step involved during decomposition and explosion reactions or these salts

In present study, a series of rare earth metal oxide (CeO2, Pr2O3, and Nd2O3) nanoparticles have been prepared by sol–gel route using Ce(NO3)3·6H2O, Pr(NO3)3·6H2O and Nd(NO3)3·6H2O, and citric acid as precursor materials. Powder X-ray diffraction, scanning electron microscopy, and transmission electron microscopy are employed to characterize the size and morphology of the nano oxide particles. The particles are spherical in shape and the average particle size is of the order of 11–30 nm. Their catalytic activity was measured on the thermal decomposition of ammonium perchlorate and composite solid propellants (CSPs) by thermogravimetry (TG), TG coupled with differential thermal analysis (TG–DTA), and ignition delay measurements. The ignition delays and activation energies are found to decrease when rare earth metal oxide nanoparticles were incorporated in the system. Addition of metal oxide nanoparticles to AP led to shifting of the high temperature decomposition peak toward lower temperature and the burning rate of CSPs was also found to enhance. However, E
 a activation energy for decomposition was also found to decrease with each catalyst.
