We show that two distinct methods, electropolymerization and initiated chemical vapour deposition (iCVD), can be adapted to generate ultrathin polymers (30–50 nm thick) at three dimensionally (3D) porous conductive substrates comprising ∼300 μm-thick carbon-coated silica fiber paper (C@SiO2).

The η-cyclopentadienyl (Cp) and η-allyl (C3H5) complexes [RhCp(CO)2], [RhCp(cod)] where cod = 1,5-cyclooctadiene, [Rh(η-C3H5)(CO)2], and [Rh(η-C3H5)3] have been shown to be useful precursors for the chemical vapour deposition (CVD) of rhodium films. The rhodium films contain carbon impurities but these can be greatly reduced if CVD is carried out in the presence of hydrogen. The films adhere well to a silicon substrate. The pyrolysis of [RhCp(CO)2] gives CO and [Rh2Cp2(CO)2(μ-CO)] and [Rh3Cp3(μ-CO)3] at intermediate stages. Pyrolysis of [Rh(η-C3H5)3] or [Rh(η-C3H5)(CO)2] gives 1,5-hexadiene as the only organic product, but similar pyrolysis in the presence of hydrogen gives much propene as well as 1,5-hexadiene. Key words: rhodium, deposition, allyl, cyclopentadienyl.

ABSTRACTSi1−xGexY alloy nanocluster materials are synthesized by the chemical vapour deposition of Si2H6/Ge2H6 mixtures within the diamond lattice of 13Å supercages in acid zeolite Y. A multianalytical approach to the study of these Si1−xGexY nanomaterials over the full compositional range 0<x<1 provides information concerning the mode of formation, geometric and electronic structures, trends in the optical properties of the encapsulated alloy nanoclusters.

The presence of active catalyst during graphene growth by alcohol catalytic chemical vapour deposition is a compulsory. This study is aimed to validate the effect of annealing temperature for the formation of active cobalt oxide (Co3O4 ) film on the graphene growth by alcohol catalytic chemical vapour deposition technique. Active Co3O4 film was prepared on silicon wafers by sol-gel process, using cobalt acetate tetrahydrate as the precursor compound and absolute ethanol as the solvent. The active Co3O4 phase was achieved by annealing process at 450, 500, 550 and 600 °C. The graphene is grown from active Co3O4 film under 900 °C of chemical vapor deposition (CVD) processing temperature for 5 minutes. The obtained Co3O4 was characterized by x-ray diffraction and Raman spectroscopy. The as-grown graphene from active Co3O4 film annealed at 450 ⁰C was characterized by Raman spectroscopy and field emission scanning electron microscope (FESEM). The results demonstrate that spinel type cubic structure of Co3O4 could be produced at the varied annealing temperatures but the optimum XRD result was at 500 ⁰C annealing temperature. The presence of active Co3O4 phase was supported with the exhibited peaks of four Raman-active phonon modes in the Raman spectra. The quality of as-grown graphene determined from the ratio of 2D-band over G-band intensities is 1.010; an indication of few layers of graphene. Active Co3O4 film is able to produce good quality of graphene comparable with Ni and Cu catalysts. And graphene can be used in many devices, including electronic device, energy storage device, power device, and others.

The current study aimed to describe the fabrication of a composite patch by incorporating marine algae powders (MAPs) into poly-lactic acid (PLA) for bone tissue engineering. The prepared composite patch was functionalized with the co-polymer, poly (2-hydroxyethyl methacrylate-co-ethylene glycol dimethacrylate) (p(HEMA-co-EGDMA)) via initiated chemical vapor deposition (iCVD) to improve its wettability and overall biocompatibility. The iCVD functionalized MAP–PLA composite patch showed superior cell interaction of human osteoblasts. Following the surface functionalization by p(HEMA-co-EGDMA) via the iCVD technique, a highly hydrophilic patch was achieved without tailoring any morphological and structural properties. Moreover, the iCVD modified composite patch exhibited ideal cell adhesion for human osteoblasts, thus making the proposed patch suitable for potential biomedical applications including bone tissue engineering, especially in the fields of dentistry and orthopedy.
