    Notes: Abstract Bulb scale propagation makes it difficult to obtain a large number of bulblets from disease-free stocks in a short time. The establishment of improved micropropagation procedures by in vitro culture is therefore desirable. Easter lily (Lilium longiflorum Thunb.) filaments with and without anther were excised and cultured in vitro with different media and culture conditions. In cultures of filaments with anther, callus developed and led to bulb, shoot, and root formation, whereas in cultures of filaments lacking anther, callus development did not occur. Among the various media tested, the B5 medium combined with darkness and the N6 medium combined with darkness or light, both supplemented with 9% sucrose, proved to be superior. A total of 1260 plants were regenerated from callus, acclimatized under a mist, and transferred to the greenhouse with a 100% success rate. No morphological abnormalities were observed among plants regenerated from filament-derived callus and all plants displayed isozyme banding patterns identical to the original cultivar. Chromosome observations revealed that all callus-regenerated plantlets tested were diploid (2n=24). The results suggest that in vitro culture of filaments with anther can be cultured for mass propagation.

    Optimisation of the electrochemical bath for growing device-quality CuInSe2 thin films (1998)

    Notes: The electrochemical bath used for growing device-quality CIS (CuInSe2) thin films by co-deposition as well as layer-by-layer (LBL) deposition was characterised and optimised with respect to the film properties. The bath composition was varied by changing the Cu, In and Se ion concentrations in specific ratios in both co-deposition and LBL deposition. The film properties were analysed using techniques such as SEM (scanning electron microscopy), EPMA (electron probe microanalysis), AES (Auger electron spectroscopy) and XRD (X-ray diffraction). The structural, morphological and compositional properties of the films were characterised and their variation is attributed to the bath composition and growth conditions. © 1998 John Wiley & Sons, Ltd.

    Growth modes of solution-grown CdS thin films (1995)
    New York, NY [u.a.] : Wiley-Blackwell
    Advanced Materials for Optics and Electronics 5 (1995), S. 11-17

    ISSN: 1057-9257
    Keywords: CdS ; chemical deposition ; complexing agent ; sulfurising agent ; Chemistry ; Polymer and Materials Science

    Notes: The growth modes of CdS thin films on glass in a chemical bath were analysed using scanning electron microscopy and optical microscopy. The results of these studies show that the film growth occurs by ion-by-ion condensation and by colloidal particles of CdS adhering to the substrate. Both mechanisms are operative from the initial stages of film growth. The predominance of one or other of these two growth modes depends on the abundance of Cd and S ions present in the solution, which is determined by the amount of complexing and sulphurising agents and ammonia used for the controlled release of Cd and S ions into the solution. The growth mode influences the optical properties of the films.
