In order to characterize stable composites that will contribute industrial applications, polypyrrole (PPy)/huntite were prepared by the physical method. Polypyrrole produced at various huntite concentrations (10, 20, 30, 40 wt.%). Polypyrrole/huntite was characterized Fourier transform infrared spectroscopy (FTIR), Thermal Gravimetric Analyses (TGA), Differential (DTA), Scanning electron micros...

Emission in the nanostructured materials is important in micro/nanoelectronic devices. We report here a strategy for the processing of micron and submicron fibers from a cobalt-containing hyperbranched polysilazane by electrospinning. The electrospun nanofibers have uniform average diameters of ~600 nm and lengths of ~10 μm. The photophysical properties of polycobaltsilazane (PCSN) are studied ...

Potassium Pentaborate nonlinear optical (NLO) material was synthesized by the solution growth method. The grown crystals were subjected to structural, optical and mechanical property studies. Crystal with excellent transparency were grown with maximum size of 9mm×8mm×5mm and the grown crystals were characterized by single crystal Single crystal XRD, FT-IR, TGA-DTA&DSC, and UV–vis-NIR studies. T...

Growth of bis (thiourea) cadmium formate single crystals from aqueous solution by slow evaporation technique has been reported. To optimize the growth conditions, nucleation parameters such as metastable zone width and induction period values are determined. The grown crystals are characterized by powder XRD technique. Thermal studies by TGA and DTA techniques confirm the decomposition of the s...

A "basophilic method" for phenolic hydroxyl bridged lanthanide coordination polymers (CPs) was developed. With this method, eleven CPs with the general formula of [Ln(HL1)L1·H(2)O](n) (Ln = Tb (1), Nd (2), Eu (3), Gd (4), La (5), Er (6), Y (7), H(2)L1 = 4-methyl salicylic acid) and [Ln(HL2)L2·2MeOH](n) (Ln = Eu (8), Tb (9), Gd (10), La (11), H(2)L2 = 3-hydroxy-2-naphthoic acid) were synthesized...

This work describes the application of oxo-derivatives of fullerene C60 and pristine fullerene as a nanocomposite in polymerous nanofibres. In this work we used oxofullerene derivative, of which preparation was presented by the authors of the State office for nuclear safety (Prague) on Nanocon 2009 and on Nanocon 2010 [1, 2]; there was presented its application in vivo as a radioprotective agen...

Hydrogenated amorphous silicon oxide photoluminescent nanopowders have been synthesized using a simple solution method involving the reaction of lithium with trichlorosilane in tetrahydrofuran at room temperature. The powders exhibited maximum luminescent peak at 1.1 eV and had an average composition of SiO0.92H0.53. They possess inhomogeneous microstructures that contain a-Si clusters (Si3–Si–...

Carbonized eggshell powder a solid lubricant with absorbent capability has proven as reinforcement metallic base composites. In present work, an attempt made investigate effec...

Novel metal(II) complexes derived from 2-hydroxy-N'-((Z)-3-(hydroxyimino)-4-oxopentan-2-ylidene)benzohydrazide ligand (H2L) were synthesized and characterized by elemental and thermal analyses (DTA and TGA), IR, UV-VIS, (1)H-NMR, ESR and mass spectroscopy, magnetic susceptibilities, and conductivities measurements. The complexes adopt distorted octahedral geometry. The ESR spectra of the solid ...
