ITO thin films were prepared at 550°C by a sol-gel method using colloidal particles derived from a solution of indium nitrate and tin chloride. The colloidal particles were secondary particles with about 50nm in diameter and were dispersed by adding indium chloride as a peptizer to prepare a dipping solution. Firing o…

In the present work, the electronic structure of polythiophene at several doping levels is investigated by the use of the H\"uckel Hamiltonian with \ensuremath{\sigma}-bond compressibility. Excess charges are assumed to be stored in conformational defects of the bipolaron type. The Hamiltonian matrix elements represen…

The ESR spectra for a series of binuclear trigonal bipyramidal copper complexes show that the SOMO is largely composed of the two equivalent dz2 orbitals on copper; the temperature independence of the ESR parameters shows that this is a relatively strong bond, and since the unpaired electron is antibonding, the σ-bond…

The promotion of oriented calcie crystallization by various polyelectrolytes , in particular their relative efficiency, has been investigated. Gelatin containing polyelectrolytes was found to overcome the compatibility problem between an inert matrix and the water‐soluble polyelectrolytes as sociated with biomineraliz…

Hydrogen uptake in zirconium alloy CANDU (CANada Deuterium Uranium) pressure tubes and other core components is controlled by the rate of transport of atomic/ionic species across the oxide film. The importance of understanding the mechanism of transport stems from the need to predict and control the rate of uptake. Sa…

Prolonged photolysis of aqueous solutions containing [V4O12]4– and MeOH at pH 9 (pH adjusted by use of K2CO3) led to the formation of K5H2[V15O36(CO3)]·1 4.5H2O. A single-crystal X-ray structural analysis of dark green crystals of K5H2[V15O36(CO3)]·14.5H2O [triclinic, space group Pa= 12.361 (4), b= 18.149(5), c= 11.41…

Drying processes are complex because of the non-linearity of physical phenomena and of the distributed parameter character on many levels of consideration. At different scales the relative importance of phenomena will differ. A discussion of the level structure is presented and the concept of “critical grain size” is…

The isotopic distribution of carbon dioxide desorbed from an MgO surface containing adsorbed 18O-labelled carbon dioxide (C18O2) has been measured by temperature-programmed desorption (TPD), in order to study acid–base pair sites on the surface. Three desorption peaks, differing in both isotopic distribution and tempe…

Catalysis of Diels–Alder reactions by various clay minerals exchanged with a variety of transition metal cations was shown to occur readily at ambient temperatures in a variety of solvents. Nontransition and lanthanide cation-exchanged clays were found to be ineffective. α,β-Unsaturated carbonyl compounds (such as met…

To understand the mechanisms of photo-induced vitreous liquefaction, this study investigated the effects of free radicals on collagen and hyaluronic acid (HA). Bovine vitreous collagen or HA was irradiated by visible light in the presence of riboflavin (RF) as a photosensitizer. The changes in the molecular weight of…
