Since its first appearance in 1954, polypropylene (PP) has become one of the most important commodity polymers. Among the outstanding properties of polypropylene are: low density, high melting point (167°C), high tensile strength, great rigidity, better stress crack resistance than high density polyethylene, and high…

Closed formulas are given for the calculation of the orientation matrix and the angles for a given reflection in a `z-axis' diffractometer geometry. These equations are derived for the conditions where the angle of incidence of the primary beam to the surface of the crystal is specified. Comparison is made with the st…

Crystalline silver( III ) oxide , which is stable over prolonged periods at −20°C, was obtained by anodic oxidation of AgClO 4 , AgBF 4 or AgPF 6 (not AgNO 3 ) in aqueous solution. The oxide of definite composition Ag 2 O 3 was hitherto unknown. It arouses interest as a possible component of the anodes in zinc/silver…

The reaction of zinc octaethylporphyrin with N 2 O 4 in dichloromethane gives, in a stepwise reaction, the zinc complexes of mono-, di-, tri-, and tetra-nitrooctaethylporphyrins. Demetallation, under acidic conditions, gives the corresponding free base porphyrins. The meso-nitro groups exert both steric and electronic…

The corrosion processes occurring in archaeological iron artifacts are discussed in the light of published measurements of electrode potentials and pH, and the relevance of this to the selection of conservation procedures is considered. In particular it is concluded that wet anaerobicstorage of ironwork should be succ…

Abstract The instability of palygorskite and sepiolite under soil conditions was investigated to determine if these fibrous minerals transform directly to smectite under laboratory conditions. The treatment of 100 mg (0.12 mmole) of palygorskite with 1 mmole of NaOH solution (17 ml) at 150°C for 24 hr yielded a smecti…

Pseudomonas fluorescens PHK uses 4,5-dihydroxyphthalate as the sole carbon source for o-phthalate catabolism. This intermediate is the substrate for a decarboxylase of the pathway yielding protocatechuate. The decarboxylase was purified to homogeneity by an affinity chromatography procedure in which the reaction produ…

Partition ratios of zinc and lead between synthetic granitic melts and aqueous phase were determined at 800 degrees C and under P (sub H 2 O) = 3.5 + or - 0.25 kb. Two starting glasses in the system SiO 2 -Al 2 O 3 -CaO-Na 2 O were prepared. Their bulk chemical compositions are similar, i.e., SiO 2 content of 75.65 pe…

The effect of fluorine substitution into a mesogenic system depends critically on the manner in which it is introduced. The relative stabilities of smectic and nematic phases may be inverted by altering the site of substitution, and lateral fluorination is particularly interesting for the strong suppression of smectic…

Cellulose samples from cotton and wood pulps with varying low degrees of crystallinity (mechanically decrystallized) were studied. The influence of initial cellulose crystallinity on sugar yield after enzymatic hydrolysis was determined by two different methods. As expected, samples with low crystallinity were much mo…
