Abstract Intercalation of naphthalene and anthracene into alkyltrimethylammonium (C n H 2n+1 (CH 3 ) 3 N + ; n = 8, 12, 14, 16, and 18)-montmorillonites was carried out by novel solid-solid reactions at room temperature. Octyltrimethylammonium(C8)-montmorillonite did not form an intercalation compound with either naph…

The development of heat affected zone microstructures in super duplex stainless steels (nominal composition Fe–25·0Cr–3·5Mo–7·5Ni–O·5Cu–0·25N–0·5W wt-%) has been examined on multipass welds, bead-on-plate welds, and simulated weld samples. Three-dimensional heat flow equations, for different plate thicknesses, have be…

Magnesium sulfate's attack on cement‐based materials results in massive deposition of gypsum and brucite accompanied by decalcification of calcium silicate hydrate (CSH) (the binding material of the cement). Magnesium silicate hydrate (MSH) appears as a late‐stage product, mainly on deteriorated surfaces, and replaces…

Abstract An efficient method is reported for the preparation of metallophthalocyanines (MtPcs) with D2h symmetry (di-substituted type). A ZnPc with D2h symmetry thus obtained has been characterized by NMR, absorption, fluorescence emission and excitation and magnetic circular dichroism (MCD) spectroscopy, together wit…

Abstract The thermal degradation of polymethacrylic acid was found to have two separate decomposition regions. The first decomposition region, due to anhydride formation primarily, was caused by the conversion of polymethacrylic acid to polymethacrylic anhydride. This reaction followed first‐order kinetics and had an…

Abstract Sorption and diffusion of water vapor are investigated gravimetrically for polyimide films. The activity dependence of the solubility and diffusion coefficients, S and D , respectively, is classified under four types: (1) constant S and D type, (2) dual‐mode sorption and transport type, (3) dual‐mode type fol…
