چکیده

Ambient S annealing was adopted to regulate the crystallinity of a ZnS microsphere, which resulted in a significant improvement in the photocatalytic hydrogen production activity (PHPA). Moreover, with S ambient treatment, wurtzite ZnS showed better PHPA than sphalerite ZnS, possibly because the inter-polar electric field of the wurtzite phase could promote the separation of photo-excited electron–hole pairs.

Performance of the Atmospheric Cherenkov Imaging Cam- era for the CANGAROO-III Experiment

A Cherenkov imaging camera was developed and installed in the second telescope of the CANGAROO-III project for observing gamma-rays having energies above 10eV. The camera consists of 427 pixels, arranged in a hexagonal shape at 0.17◦ intervals, each of which is a 3/4-inch diameter photomultiplier with a Winston-cone–shaped light guide. The camera discussed in this paper offers a wider field of ...

Model-driven Transformation and Validation of Adaptive Educational Hypermedia using CAVIAr

Authoring of Adaptive Educational Hypermedia is a complex activity requiring the combination of a range of design and validation techniques. We demonstrate how Adaptive Educational Hypermedia can be transformed into CAVIAr courseware validation models allowing for its validation. The model-based representation and analysis of different concerns and model-based mappings and transformations are k...
