Hot Filament Chemical Vapor Deposition (HFCVD) offers the ability to tailor the chemistry of films with polymeric structure. In particular, HFCVD allows for more control over precursor fragmentation pathways than conventional plasma-enhanced CVD (PECVD). HFCVD uses thermal activation in the gas phase to generate reactive species, and allows independent control of the substrate temperature to be...

surface ozone (surface o3)is a secondary pollutant and there are only limited studies on ozone in south india. studies have revealed a strong correlation between higher ozone levels and warmer days. surface o3 along with its precursors like no2, co and ch4 are being measured at kanyakumari (8.0780° n, 77.5410° e), tamilnadu, india and in this paper we present the summer time variation of ozone ...

Abstract: Nanocrystalline MgAl2O4 spinel powder was synthesized using metal nitrates and a polymer matrix-based composed of sucrose and polyvinyl alcohol (PVA). The precursor and the calcined powders were characterized by simultaneous thermal analysis (STA), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM). According to XRD res...

The synthesis and characterization of superparamagnetic iron(iii) oxide nanowires confined within double-walled carbon nanotubes by capillary filling with a melted precursor (iron iodide) followed by thermal treatment is reported for the first time.

In the current study, synthesis and characterization of a new nano-structured zirconium(IV)-minoxidil complex (1), where minoxidil, (C9H15N5O; 6-(1-Piperidinyl)-2,4-pyrimidinediamine 3-oxide), have been investigated in two different solvents. The compound 1 has been synthesized by sonochemical method in the presence of methanol and monoethylene glycol (MEG) as solvents and characterized by scan...

a r t i c l e i n f o Thin-films and organic field-effect transistors fabricated from a solution-processable precursor of zinc tetra-benzoporphyrin (ZnTBP) are reported. Amorphous, insulating precursor films were deposited by spin-casting and thermally converted into polycrystalline, semiconducting thin-films comprising grains on the order of 5 μm in diameter. Thin-film X-ray diffraction indica...
