Facile green synthesis of silicon nanoparticles from for fluorescence based detection of Fe(iii) ions.

Fluorescent silicon nanoparticles (SiNPs) might be one of the excellent candidates for use as optical markers in biological profiling and diagnostic applications. To exploit this perspective, they ought to be essentially synthesized from any green precursor rich in silicon. Stable dispersibility in water along with prolonged luminescence under different conditions is also desired.

Efficient chemical vapour deposition and arc discharge system for production of carbon nano-tubes on a gram scale.

Three indigenous systems-the underwater arc discharge setup, the inert environment arc discharge system, and the chemical vapor deposition (CVD) system-for the gram-scale production of carbon nanotubes were designed and fabricated. In this study, a detailed description of the development and fabrication of these systems is given. Carbon nanotubes were synthesized by using all the three systems, and comparative analyses of the morphology, composition, and purity were done.
