Silicon-29 n.m.r. spectra have been obtained for a number of aqueous solutions of sodium and potassium metasilicate. The assignment of peaks to various silicate species is discussed. Linewidth and spin–lattice relaxation time measurements are reported as a function of ageing of the solutions in sealed glass tubes, and…

X‐ray photoelectron spectroscopy (ESCA) has been employed to examine several elemental metal foils which were simultaneously allowed to develop natural passivation (oxidation) layers. The metals considered included representative transition metals and also several Group III and IV elements. Sputter etching was employe…

Differential scanning calorimetry (d.s.c.) and nuclear magnetic resonance (n.m.r.) techniques were used to study the melting of ice in porous solids.At low water contents (less than about three monolayers) no freezing or melting was observed. As the water content was increased, a single melting peak was observed as th…

Microcrystalline cellulose (M.C.C.) having various ratios of crystal region to amorphous one obtained by grinding. Crystallinity was determined for M.C.C. and ground M.C.C. by X ray diffraction method (powder method) using Hermans'theory. Crystallinity was also determined by infrared measurement in converting hydroxyl…

The production of radioactive nuclei during the operation of a light-water reactor is traced, and their decay history is followed. The potential environmental impacts of this waste are calculated and shown to be comparable to those of other materials we produce. Assuming deep burial, it is shown that there are importa…

The syntheses of four binary porphyrins, two of which are constrained to a "face-to-face" conformation, and their Co2+ and Cu2+ derivatives are described. Electron spin resonance indicates that the intermetallic separation in the binuclear "face-to-face" porphyrins is about 6.5-6.8 A. Electronic spectra and proton mag…

Recent theoretical calculations of the properties of rare gases, and in particular Helium, in the common f.c.c. and b.c.c. metals, are reviewed from the viewpoint of the investigator concerned with the behaviour of rare gas in such radiation damage processes as surface blistering and void swelling. Particular attentio…

A new nondestructive technique is described which provides information about the distribution of charges in nonpolar electrets. Changes in the equivalent electret voltage are measured during and after the absorption of a short pulse of heat on one side of an otherwise well thermally isolated electret. The total electr…

Abstract The morphology of porous polysulfone hollow fibers which were spun by the dry–wet spinning process is discussed. It was demonstrated that a relatively moderate quenching medium should be employed in the bore of the nascent fiber in order to produce an isotropic fiber free of macrovoids and intrusion cells. A…

The effect of the presence of gaseous hydrogen on the mechanical properties of steels is presented. This phenomena, generally known as hydrogen embrittlement, is shown to be dependent on the ability of the steel to adsorb hydrogen. A series of crack‐growth and adsorption experiments clearly shows that the supply of hy…
