Opis:
Synthesis of materials with acceptable performance and low sensitivity to physical stimuli is one of the overall goals of energetic materials. The creation of networks of hydrogen bonds affords good stability to the trigger bonds. In this respect azole-based ionic high-energy materials (especially aminotetrazoles) and other nitrogen-rich compounds have strong hydrogen bonds. Significant stability, insensitivity to a physical stimulus and also good performance are thus created. In this study salts derived from N-(1-carboxymethyl-1H-tetrazole-5-yl)-hydrazinium chloride were synthesized. Anion exchange of the chlorine with nitrate, 5-aminotetrazolate, (5-amino-tetrazole-1-yl)-acetate and (5-nitriminotetrazole-1-yl)-acetate was performed, with precipitation of AgCl. All of the products were characterized using 1H NMR, 13C NMR, FTIR spectroscopy, differential scanning calorimetry (DSC), impact sensitivity and UV-Vis spectroscopy. Among the advantages of this study are the use of methods and available equipment and low-risk solvents during the reaction and the formation of minimum by-products.

Opis:
Montmorillonite is an important clay mineral due to its cation exchange capacity and technological properties such as swelling and gelling. It has been widely used in many scientific applications like organoclay. Adsorption studies, involving montmorillonite in the presence of variety of organic compounds, like ammonium and phosphonium salts, are very important because of their application in organoclay and polymer nanocomposites. These materials have a high thermal resistivity. Different types of phosphonium salts, including hexadecyl triphenyl phosphonium bromide (HTPB), hexadecyl tributyl phosphonium bromide (HTBPB), and tetraphenyl phosphonium bromide (TPB), were used to investigate their adsorption on Na-montmorillonite. They have different structures and TPB contains only one aromatic part without any organic chain, HTBPB possess an organic chain with three branches while HTPB has an organic chain and an aromatic part. The adsorption of the surfactants was supplemented with other properties such as zeta potential, surface tension, and ability to flocculation. The results indicated that the adsorption behavior of these surfactants depended on their structure.

Opis:
This paper presents the results of a fi eld study on using mineral materials (fine-grained sand and medium- -grained gravel) to reduce the concentration of readily soluble salts in a roadside environment. The investigated soils were Rendzic Sceletic Leptosols from an urban area characterized by a shallow humus horizon with a high content of skeletal parts, as well as a lack of homogeneity of the material in the soil profile. All soil samples were taken from five plots located along the main streets in the city of Opole (Southern Poland). It was revealed that the use of fine-grained sand and medium-grained gravel improved the structure of the surface soil layer, and thus favoured the migration of Na+ and Cl- ions into the soil profile. In comparison to control surfaces readily soluble salts were reduced with gravel and sand application. Furthermore, the mineral materials introduced on the soil surface for salinity neutralization did not affect the quality of the tested roadside calcareous soils. The results indicate that the use of mineral materials reduces soil salinity caused by NaCl. They also show the need to find new methods of salt neutralization, especially of roadside soils in order to improve and protect the quality of the environment.

Opis:
The study was aimed at mineralogical and geochemical characteristics of secondary phases related to deterioration of historic building materials. The investigations, carried out in the Holy Trinity Basilica in Kraków, Poland, focused on the southern facade of the 17th-century Myszkowskis Chapel, built of the Miocene Pińczów limestone. Lower part of the facade is covered with a cement render, and the exposed foundations are made of Jurassic limestone and Cretaceous sandstone, both of local origin from the Kraków region and neighbouring Carpathians, in the form of irregular blocks bound with a cement mortar. The wall surface exhibits clear signs of damage; from dark grey soiling and scaling to efflorescences. Sampled materials, deteriorated, altered crusts and efflorescences were analysed with optical and scanning electron microscopy, X-ray diffraction, and Raman microspectroscopy methods. The secondary minerals distinguished include abundant gypsum CaSO42H2O, less common thenardite Na2SO4 (and/or mirabilite Na2SO410H2O), aphthitalite (K, Na)3Na(SO4)2, darapskite Na3(SO4)(NO3)H2O, ettringite Ca6Al2(SO4)3(OH)12 26H2O, monosulphite Ca4Al2O6SO311H2O, as well as scarce nitre KNO3, nitratine NaNO3 and halite NaCl. Gypsum usually forms surface crusts and fills the pores inside some materials. The efflorescences, sampled from the exposed foundations, consisted of thenardite and/or mirabilite, aphthitalite and darapskite, whereas ettringite and monosulphite were connected with cement renders. Traces of nitre, nitratine and halite were detected at various elements of the chapel facade and foundations. The origin of the salts is related to composition and physicochemical properties of the building materials, as well as to anthropogenic factors.

Opis:
Aminoguanidinium perchlorate (2, AGClO4) was formed by the reaction of aminoguanidinium bicarbonate (1) with aqueous perchloric acid solution. Triaminoguanidinium perchlorate (3, TAGClO4) was synthesized by nucleophilic attack of aqueous hydrazine solution on aminoguanidinium perchlorate under release of ammonia. The new and highly explosive azidoformamidinium perchlorate (4, AFClO4) was formed by the reaction of aminoguanidinium perchlorate with potassium nitrite under acidic conditions. The structures of the perchlorate salts in the crystalline state were determined using low temperature single crystal X-ray diffraction yielding monoclinic as well as orthorhombic structures. The compounds were characterized comprehensively using vibrational spectroscopy (IR and Raman), multinuclear (1H, 13C and 15N) NMR spectroscopy, elemental analysis and mass spectrometry. The thermal behavior as well as the decompositions were investigated using DSC (differential scanning calorimetry) and the heats of formation were calculated using heats of combustion determined by bomb calorimetric measurements. In addition, the sensitivities were evaluated using BAM methods (drophammer and friction tester), whereby the perchlorate salts are all sensitive towards impact as well as friction.

Opis:
The effect of cyanide salts as depressants, i.e. sodium cyanide (NaCN) and complex cyanide salts such as potassium ferricyanide (K3Fe(CN)6) and potassium ferrocyanide (K4Fe(CN)6), as well as combination of sodium cyanide with ferrous sulphate (FeSO4/NaCN) on pyrite flotation was investigated. Tests covered the frothless flotation of pyrite under different concentrations of depressants at various solution pH’s with potassium butyl xanthate (KBX) as collector. Flotation test results have shown that NaCN, and even more the combination of reagents FeSO4/NaCN are more successful in pyrite depression than complex cyanide salts, such as K3Fe(CN)6 and K4Fe(CN)6. Surface characteristics of pyrite were studied using rest potential (Eh) measurements and infrared attenuated total reflection spectroscopy (ATR-IR). In the presence of tested reagents in the flotation system, iron cyanide compounds and hydrated iron oxides were formed on pyrite surface. The composition of formed compounds depends not only on cyanide ions in the solution, but also on the pH of the system and solution species. These compounds, depending on the reagents used, are responsible for the resulting efficiency of the pyrite depression.

The impact of winter addition of salts to roadside soils was studied for the national road No. 28 in Poland, in Małopolska Region. The measured sections of the road No. 28 are two access ways to the city of Grybów. According to instructions of GDDiKA (General Directorate for National Roads and Motorways) both sampled routes: Grybów–Gorlice (sampling section G-G) and the section Nowy Sącz-Grybów (N-G) were included in II standard of winter road maintenance. The general increase in soil salinity, chloride concentration and pH values from the roadside soils was evidenced by the difference of results of two sampling campaigns, before and after winter season of 2015/16. Salinity indicators showed significant increase, even though weather winter season 2015/16 was rated as mild and road de-icing salts were applied at less-than-average rate. Soil hydraulic properties were calculated estimated from soil texture using pedo-transfer functions for estimating the dynamics of salts into soils, suggesting easy leaching of salts from topsoil.

Opis:
Energetic salts as a unique class of energetic materials have recently been investigated widely, since they possess advantages over their atomically similar nonionic analogues – they tend to exhibit lower vapor pressures, higher densities and better thermal stabilities. Furthermore, these salts are readily improved upon by the appropriate combination of different cations and anions. Over the last twenty years, our group has continued to synthesize and study novel ionic energetic materials. Here, we have summarized all of the series of nitrogen-rich energetic salts. This review gives an overview of the various studies dealing with synthetic aspects and some of the physicochemical properties of ionic compounds that are based on ammonia, guanidine, semicarbazide, carbohydrazide, tetrazine, tetrazole, triazole and imidazole. In addition, their potential applications in the fields of explosives and propellants are discussed. We hope these investigations will be helpful in providing a wider insight for future research in the area of energetic salts.

Opis:
For last several years we have studied modifications of montmorillonite (MMT) with different agents and the structural changes resulting from the processes. The aim of present work was focused on the preparation of polymer composites from epoxy resin and dispersed phase modified chemically and subsequently activated by irradiation. The paper presents investigations concerning intercalation of MMT by the synthesized unsaturated organophilic agents (on the basis of quaternary ammonium salts). The process was studied by: wide-angle X-ray scattering (WAXS), Fourier- -transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA); additionally mechanical properties of the polymer composite as well as its microscopic structure were tested. It was found that unsaturated quaternary ammonium salts can intercalate between MMT layers. The possibility of radiation-induced compatibilization between modified MMT particles and polymeric matrix was also studied. It was confirmed by electron paramagnetic resonance (EPR) spectroscopy that in the synthesized salts stable radicals are formed during irradiation, however their influence on mechanical properties of the final composite is insignificant.

Tak zwane sole bitumiczne są rodzajem skał solnych wykazującym znaczną zawartość węglowodorów nadającą im specyficzny kolor i zapach. W wysadzie kłodawskim występują w formie nagromadzeń o różnych wielkościach i kształtach. Najczęściej tworzą one nieregularne smugi, soczewki lub pasma o zróżnicowanych barwach zmieniających się od jasnożółtego po ciemnobrązowy. Badania petrologiczne tych utworów w płytkach grubych wykazały obecność bardzo różnorodnie wykształconych zespołów inkluzji fluidalnych. Zmienność ta dotyczy zarówno rozmiarów i kształtów inkluzji, jak i stosunku fazy gazowej do ciekłej oraz roztworów do zawartości węglowodorów. Pod tym względem wyróżnionych zostało siedem głównych typów zespołów inkluzji, pomiędzy którymi występują typy pośrednie. Występujące w poszczególnych zespołach inkluzji węglowodory także wykazują dużą różnorodność pod względem własności optycznych zarówno w świetle widzialnym, jak i ultrafioletowym.
The so-called bituminous salts are a kind of salt rocks, which display considerable amounts of hydrocarbons giving them a specific colour and smell. In Kłodawa Salt Dome they occur as concentrations of various size and shape. Most often they form irregular streaks, lenses or bands of salts with different colours changing from light yellow to dark brown. The petrological investigations of such salts in thick plates showed a presence of very different fluid inclusion assemblages (FIA). They vary in size of inclusions, their shapes, the ratio of the gas to liquid phase and the ratio of solutions to hydrocarbons. In this respect, seven main types of FIA were distinguished including intermediate types, as well. Hydrocarbons occurring in singular FIA also show diversity in terms of optical properties in visible and ultraviolet light.

Opis:
Pathogenic microorganisms like fungi, bacteria and algae are harmful to human beings and animals. Moreover, they contribute to the destruction of building materials by their biodegradation. Therefore, they create serious hazard for the natural environment. To prevent these phenomena, different materials with biocidal activity are being developed. In elaboration of such materials, one of the most difficult problems to be solved is the achievement of their high effectiveness in controlling harmful microorganism population with the guarantee of safety of their application to the natural environment and humans. As a result of investigation carried out in the INCT on new biocides based on quaternary N-alkylammonium salts (QAC), mainly benzalkonium chloride, and water glass (WG) large group of new silica materials with biocidal activity were synthesised. Possibilities of technology modification in order to obtain different profitable properties of materials are presented in the paper. Preliminary investigations concerning biocidal activity against selected mould fungi, bacteria and algae were performed. Results of microbiological investigations proved stable effectiveness of biocides for protection from harmful microorganisms growth, which does not decrease even after washing of biocidal material with water. Silica materials with biocidal activity due to structural binding of biocidal agent (QAC) can be applied in building industry as materials of high ecological safety.
