AbstractThe effect of coupling agents on the mechanical properties of nitrile butadiene rubber (NBR)/organophilic montmorillonite (OMMT) clay nanocomposites was studied using three different types of silane coupling agents, which were γ-(aminopropyl)triethoxysilane, γ-(mercaptopropyl) triethoxy silane, and bis-[(γ-triethoxy silane)proply] tetrasulfur. The NBR/OMMT nanocomposites were prepared via the melt compounding with OMMT clay. The effect of silane coupling agents on the dispersion of OMMT in the polymer matrix was studied by X-ray diffraction. Dynamic mechanical analysis was employed to

Abstract:
Abstract S4N4 reacts with NH4+FeBr4- in benzene to give the 1:1 inclusion compound NH4+FeBr4- • S4N4. The dark red crystals are monoclinic, space group Cc with Z = 4 and lattice constants a = 6.430(1), b = 17.644(4), c = 12.180(2) Å , and β = 90.77(3)°. An X-ray analysis shows that the geometry of the S4N4 group is almost identical to that of crystalline tetrasulfur tetranitride. The S4N4 molecule is surrounded by ionic neigbors in such a way that the S atoms form close contacts to Br atoms of the FeBr4- anions and the N atoms are close to the NH4+ cations.

Abstract:
The fast-growing interest in 1,2,5-thiadiazoles and their fused analogues including 2,1,3-benzothiadiazoles in recent years as important compounds in materials science and biomedicine has led to great progress in the synthesis of these heterocyclic systems. In this short review, the development of known procedures together with novel reactions is covered. New starting materials, unknown and unexpected transformations for the construction of the thiadiazole ring are emphasized.1 Introduction2 Synthesis of Monocyclic 1,2,5-Thiadiazoles2.1 From 1,2-Diamines, vic-Dioximes and Related Compounds2.2

Abstract:
For three energetically most stable structures of tetrasulfur, S4, S4+ and S4- (cis-chain, rectangular, and trans-chain forms), equilibrium geometries, harmonic wavenumbers, ionization energies, electron affinities, electronic vertical and adiabatic excitation energies, and electronic transition moments were calculated by ab initio methods. It was found that similarly to the ground state of S4, the S4+ cis-isomer could interconvert, perturbed, however, by vibronic coupling with a very close-lying excited state and large-amplitude vibrations. Moreover, the cis- and rectangular minima are calcul
