Abstract— The photosensitized oxidation of L‐tryptophan by gallium phthalocyanines sulfonated to different degrees is studied as a function of both substrate and sensitizer concentrations in water and 50% MeOH‐H 2 O solutions. The maximum quantum yield of singlet oxygen was found to be nearly 0.5 for all sulfonated ga…

Abstract Extensive areas of soils in northern New York have formed in parent materials deposited in late Quaternary water bodies. In previous studies, distinctions among these lacustrine, marine, and brackish‐water deposits have relied on the identification of fossils and continuous shoreline features; however, eviden…

Circular disc-crack-like defects randomly distributed on {111} planes have been discovered by 300kV transmission electron microscopy in diamond that had crystallized on non-faceted growth surfaces of mean orientation {100}. In a sample of ∼ 100 defects, disc diameters were narrowly distributed about a mean of 1·2 μm a…

The resistivity anomaly near 170 K in alpha -YH(D)x solid solutions due to the ordering of hydrogen into a paired configuration is analysed in detail. Defects are introduced into the ordered structure by a quench from room temperature and by electron irradiation at 20 K (Ee-=0.35 to 0.8 MeV) resulting in residual resi…

Dissolution of glass coupons with the general composition χNa 2 O.(100–χ)[0.33B 2 O 3 ·0.67SiO 2 ], with χ varying from 3 to 11, has been monitored with and without prior phase separation of the glasses. A major reduction in dissolution rates was noted upon phase separation of glasses with χ≃ 3. This was correlated wi…

Among the vinyl monomers, acrylonitrile is the only monomer used for the production of synthetic fibers. Other vinyl monomers lack cohesive forces between the molecular chains of their polymers and, hence, can not compete with acrylonitrile [1]. Acrylic fiber has replaced wool in many major applications, particularly…

The metastable chiral smectic C phases of the compounds have been made technically useful by alloying to different two- and three-component systems with enantiotropic behaviour. These systems can serve as a base for multi-component systems of higher order for optimizing various properties. In a similar way, the inconv…
