Rates of adsorption and desorption, of di-isopropyldithiophosphoric acid and tetraisopropylthioperoxydiphosphate from hexade-cane on to steel, have been measured wing 14C radiolabelled compounds. Concentration, temperature, and stirring dependence have been examined. The adsorption is surface controlled and the kineti…

The maturation process of collagen fibres was investigated by the picro-sirius red/polarization light technique in experimental wound healing, in allyl-alcohol induced subacute and chronic liver fibrosis and in human biopsy material. Evidence was obtained that collagen fibres undergo a rapid maturation in fibrotic pro…

A review is presented on the pitting corrosion of zirconium and Zr alloys when immersed in aqueous solutions at temperatures less than 100 C. The electrochemical methods (potentiokinetic, potentiostatic, and scratch) used to evaluate pitting susceptibility are described briefly. Zirconium is susceptible to pitting in…

The foliated calcite of living scallops (Pectinacea), oysters (Ostreacea), window-pane and jingle shells (Anomiacea) consists of approximately 250 nm thick sheets (folia) formed of subparallel laths joined laterally. The surfaces of these very thin folia are not the basal pinacoid of calcite (0001), as has previously…

Variations in the electrical resistivity and in the deviation from Matthiessen’s rule (DMR) during quench-ageing have been observed on low-carbon aluminium-killed steels containing varied amounts of manganese. The DMR is measured by the difference between the resistivities at 273 K and at the liquid-nitrogen temperatu…

The dimeglumine salt of the Gd-DTPA complex has a strong paramagnetic effect and a very low toxicity in animals. This report of its use in human volunteers confirms its low toxicity and indicates its usefulness in the enhancement of signal intensity of the kidney and bladder.

Liposomes, microscopic particles composed of lipid bilayer membranes, can carry water-soluble drugs in their aqueous compartments and lipid soluble drugs in their bilayers. Over the last 10 years, they have been studied more intensively than any other type of drug carrier. The first impulse, as with other pharmaceutic…

Solid-state polymorphic transformations can have a profound influence on the processing and storage of some crystalline powders. Using classical models of nucleation and growth a framework is developed which highlights the importance of crystal size on the transformation rate. A key parameter in this theory is the rat…
