We report a study of the self-assembled monolayer (SAM) growth of bis[3(triethoxysilane)propyl]tetrasulfide (Tetrasulfide) on low dielectric constant (low-k) aromatic hydrocarbon SiLK whose surface chemistry was modified using sulfuric acid, He plasma treatment, and N2 plasma treatment. X-ray photoelectron spectroscopy (XPS) spectra show that there is no detectable growth of Tetrasulfide SAM on...

Abstract This article presents the assessment of bulk and in situ mechanical properties rubber–wood–plastic composites (RubWPC) their correlations, aiming to obtain a thorough understanding behaviour RubWPC, which is an essential prerequisite realising optimal design applications. Dynamic analysis results showed that treated with multiple coupling agents (combination maleic anhydride polyethyle...

Sulfonic acid-incorporated-MCM-41 mesoporous materials prepared using a silane containing tetrasulfide linkages showed exceptional yields of the acetylated product in the acetylation of anisole due to their high content of strong acid sites.

Activation of bis-o-phenylene tetrasulfide to render it a practical benzodithiete equivalent for [4+2] cycloadditions with alkenes has been achieved with catalytic amounts of Mo(tfd)(2)(bdt) (tfd = S(2)C(2)(CF(3))(2); bdt = S(2)C(6)H(4)). Substituted 2,3-dihydro-1,4-benzodithiins are produced.

Well-defined lanthanide polysulfide complexes containing S4(2-) and S5(2-) ligands, the samarium(iii) pentasulfide complex Sm(Tp(iPr2))(κ(1)-3,5-(i)Pr2Hpz)(S5) and the tetrasulfide-bridged binuclear ytterbium(iii) complex (μ-S4)[Yb(Tp(iPr2))(κ(1)-3,5-(i)Pr2Hpz)(κ(2)-3,5-(i)Pr2pz)]2 (Tp(iPr2) = hydro-tris(3,5-diisopropylpyrazolyl)borate), have been synthesized and structurally characterized by s...

The title compound, C(16)H(22)N(4)O(8), is a glycoluril derivative with two propoxycarbonyl substituents on the convex face of the glycoluril system. The dihedral angle between the five-membered rings in the glycoluril unit is 72.70 (2)°. The oxadiazinane six-membered ring displays a normal chair conformation. One of the propyl groups is disordered over two positions with site occupancies of 0....

Single crystals of Cu(2)ZnSiS(4), dicopper(I) zinc silicon tetrasulfide, have been prepared via high-temperature solid-state synthesis. Cu(2)ZnSiS(4) was found to have the wurtz-stannite structure type, like that of Li(2)CdGeS(4), Li(2)CdSnS(4), and Cu(2)CdSiS(4). Each sulfur anion is tetra-hedrally coordinated by two Cu cations, one Si cation, and one Zn cation, forming a three-dimensional hon...
