Preparation, X-ray crystallography and thermolysis of transition metal nitrates of 2,2′-bipyridine (Part 63)

Abstract: Recent work has described the preparation and characterization of the two complexes [Fe2(C10H8N2)4O(OH2)2](NO3)4 and [Co(C10H8N2)3]2[Co(OH2)6]·7(OH2) (NO3)8 in which both the nitrogen atoms of 2,2′-bipyridine are directly bonded with the metals. Their structures were determined by single-crystal X-ray diffraction at 296 K. Thermolysis of these complexes has been detailed by the use of TG–DTA and ignition delay measurements. Kinetics of thermal decomposition has also been established. Model free isoconversional and model fitting kinetic approaches have been applied to isothermal TG data for the decomposition of these complexes.

Studies on energetic compounds: Part 6 synthesis of ring-substituted arylammonium salts of 3-nitro-1,2,4-triazole-5-one(NTO)

Abstract: In continuation of our programme of preparing new energetic materials, fifteen arylammonium (having electron donating or attracting substituents) salts of 3-Nitro-1,2,4-triazole-5-one (NTO) have been synthesised and characterised. These compounds have been found to be ionic in nature.

Nanocobaltite: Preparation, Characterization, and their Catalytic Activity

Abstract: Mixed transition metal oxides (MTMO) nanoparticles of 3rd-series (NiCo2O4, CuCo2O4, and ZnCo2O4) were prepared by a co-precipitation method. These were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The particle size was found to be in the order of 53.0, 43.4, and 21.2 nm, respectively. The thermolysis of ammonium perchlorate (AP), AP-HTPB (hydroxyterminated polybutadiene) composite solid propellants (CSPs), and HTPB was found to be catalyzed with MTMOs and the burning rate of CSPs was also enhanced. TG and ignition delay study demonstrated that the higher temperature decomposition (HTD) of AP is catalyzed enormously by these catalysts and CuCo2O4 is the best candidate.

Kinetics of thermal decomposition of dianilinium sulphate

Abstract: The thermal decomposition of arylammonium sulphate (dianilinium sulphate) has been investigated; sulphanilic acid is found to be the decomposition product. The mean value for the energy of activation (28.27 ± 0.46 kcal mol–1) for the decomposition has been determined from isothermal TGA data [fitted in the Avrami–Erofeev (n= 2, 3)], contracting area, contracting cube, and Jacobs–Kureishy equations. Thus, the decompositon of dianilinium sulphate seems to be controlled by a random nucleation process. The results suggest that the primary step (prior to sulphonation) in the decomposition of this salt is a proton-transfer process.

Studies on energetic compounds part 15 : Transition metal salts of NTO as potential energetic ballistic modifiers for composite solid propellants

Abstract: The combustion of hydroxyl terminated polybutadiene (HTPB) - ammonium perchlorate (AP) composite solid propellants has been studied using transition metal (Mn, Fe, Co, Ni, Cu and Zn) salts of 5-nitro-2,4-dihydro-3H-1,2,4-triazole-3-one (NTO) as energetic burning rate additives. The steady burning rate (r) was considerably enhanced with Cu(NTO)2 and Fe(NTO)2 whereas moderately enhanced with Zn(NTO)2 and Co(NTO)2 at low concentration (2% by wt.). Activity of these salts has been observed during isothermal decomposition of AP at 260°C. The values of ignition delay (tiJ), ignition temperature (Tign.) and activation energy for ignition (E∗) for AP has also been lowered when these salts are added to it at 2% wt. concentration. The processing parameters as well as mechanical properties of the propellants with Cu(NTO)2 as additive have been studied in detail. The r of the propellants (both highly aluminized and less aluminized) with Cu(NTO)2 as additive at various concentrations, has been determined at h...

Energetic nitrogen-rich salts and ionic liquids.

Abstract: 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.

Food applications of natural antimicrobial compounds

Abstract: 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.
