Aerobic transformation of cadmium through metal sulfide biosynthesis in photosynthetic microorganisms

Photoregulated carotenoid biosynthesis in non-photosynthetic microorganisms.

Photoregulated carotenoid biosynthesis consists of an initiating photoactivation which bestows carotenogenic competence upon photochromogenic microorganisms. Subsequent carotenoid biosynthesis is light independent but requires microbial growth. Experimental systems have been developed for several photochromogcnic microorganisms to separate the primary photoact from the following carotenogenic r...

Morphological variations in cadmium sulfide nanocrystals without phase transformation

A very novel phenomenon of morphological variations of cadmium sulfide (CdS) nanorods under the transmission electron microscopy (TEM) beam was observed without structural phase transformation. Environmentally stable and highly crystalline CdS nanorods have been obtained via a chemical bath method. The energy of the TEM beam is believed to have a significant influence on CdS nanorods and may me...

Evolution of nickel sulfide hollow spheres through topotactic transformation.

In this study, a topotactic transformation route was proposed to synthesize single-crystalline β-NiS hollow spheres with uniform phase and morphology evolving from polycrystalline α-NiS hollow spheres. Uniform polycrystalline α-NiS hollow spheres were firstly prepared with thiourea and glutathione as sulfur sources under hydrothermal conditions through the Kirkendall effect. By increasing the r...
