SYNTHESIS OF METALLOPHTHALOCYANINES FROM PHTHALONITRILE WITH STRONG ORGANIC BASES
Abstract Several metallophthalocyanines (MPc: M=Ni(II), Co(II), Zn(II), Pb(II), Fe(II), Sn(II), Cd(II), Mg(II), and Mn(III)) were obtained by heating phthalonitrile with metal salts in alcohols in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene. Metal acetylacetonates as well as metal halides were available as meta…

The chloride corrosion behaviour of four orthodontic wires
Potentiodynamic cyclic polarization of four orthodontic alloys (wires), namely Permachrome, Elgiloy, a beta-titanium alloy and Nitinol in a 1% NaCl solution within -500 mV and +300 mV (SCE) indicated the first three alloys to be passive whereas breakdown of passivity was observed on Nitinol. The SEM examination of the…

Infrared and Raman spectra and X-ray diffraction studies of solid lead(II) carbonates
Four basic lead carbonates were prepared and identified by X-ray powder diffractometry. These were hydrocerussite (Pb 3 (OH) 2 (CO 3 ) 2 ), plumbonacrite (Pb 10 O(OH) 6 (CO 3 ) 6 ), and the two adducts MOH•2PbCO 3 (M = Na, K). New diffraction data are presented for the latter two compounds; they both have primitive he…

Human Pharmacokinetics of Iohexol
The pharmacokinetics of iohexol, a new nonionic, water-soluble contrast medium, have been determined after intravenous injection in 20 healthy volunteers, at four different dose levels (125-500 mg I/kg). The apparent volume of distribution was 0.27 1/kg, indicating distribution in the extracellular water. The biologic…
Vibrational study of CsH2PO4 and CsD2PO4 single crystals
The infrared and Raman spectra of disordered paraelectric and ordered ferroelectric phases of CsH2PO4 and CsD2PO4 single crystals have been investigated at various temperatures in the 4000–10 and 4000–0 cm−1 range, respectively. An assignment of lattice and internal vibrations in terms of symmetry species and approxim…
Thermal Expansion of Alkali Borate Glasses
The thermal expansion behavior of lithium, sodium, potassium, and rubidium borate glasses was measured. The results indicate that the “borate anomaly” in the thermal expansion coefficient occurs at ∼20 mol% alkali oxide. A maximum in the glass transformation and dilatometric softening temperatures also occurs at ∼27 m…
Wetting transitions at models of a solid-gas interface
Using mean field free energy functionals of the type employed by Sullivan, we have investigated the nature of the transition from partial to complete wetting that occurs at a solid-gas interface. We show that this wetting transition can be a first or a second order phase transition. If it is first order, as predicted…
Role of Water Vapor in Crystallite Growth and Tetragonal‐Monoclinic Phase Transformation of ZrO 2
The role of water vapor in crystallite growth and the tetragonal‐to‐monoclinic phase transformation of ZrO 2 was studied using three specially prepared samples: an ultrafine powder of monoclinic ZrO 2 obtained by hydrolysis of ZrOCI 2 , an aggregated powder of tetragonal ZrO 2 obtained by thermal decomposition of Zr(O…

Influence of Substratum Wettability on Attachment of Freshwater Bacteria to Solid Surfaces
We studied the attachment of a number of freshwater bacteria from River Sowe, Coventry, England, to test substrata. The attachment of each organism to hydrophobic and hydrophilic surfaces was evaluated, and further studies evaluated the attachment of selected isolates to a number of substrata with a range of water wet…
Evidence for a repeating 3,4-dihydroxyphenylalanine- and hydroxyproline-containing decapeptide in the adhesive protein of the mussel, Mytilus edulis L.
Previous work has shown that the permanent adhesive of the marine mussel Mytilus edulis is a protein containing large amounts of hydroxyproline (13%) and 3,4-dihydroxyphenylalanine (Dopa, 11%). The protein also known as the polyphenolic protein is produced and stored in the exocrine phenol gland of the mussel and depo…
