single-walled carbon nanotubes (swnts) with high yield and quality were synthesized using chemical vapor deposition (cvd) over co-mo/ mgo nanocatalyst in a fluidized bed reactor. different parameters such as temperature, the ratio of hydrocarbon source to hydrogen, the flow rate of gas, growth time, the size of catalyst particles, heating rate, and the kind of hydrocarbon source were examined t...

Two alkaline earth metal-based carboxylate systems, [Mg(HL)(H2O)2]n (1) and [Ca(H2L)2]n (2) (H3L = chelidamic acid) have been hydrothermally synthesized, and characterized by single-crystal X-ray diffraction, IR, elemental analysis, and thermo-gravimetric analysis. Compound 1 has a 2D structure incorporating two water molecules. The dehydrated species, 1a, generated from 1 by removal of the coo...

Some new mononuclear complexes [ML1L2(NO3)2 ] {where M = [Co(II), Ni(II), Cu(II) and Zn(II)], L1 = 2Hydroxy-5-nitrobenzaldehyde and L2 = diketones (Pentane-2,4-dione, 1-phenylbutane-1,3-dione, 1,3diphenylpropane-1,3-dione)}, have been synthesized and were characterized by elemental analysis, molar conductance, , FTIR spectra, UV, magnetic moment and thermo gravimetric analysis (TGA). The relati...

Intercalation products based on ionic exchange reaction between cationic dye methylene blue and Na-montmorillonite were prepared. Montmorillonite particles intercalated with methylene blue were characterized using X-ray diffraction, infrared spectroscopy, elemental and thermo-gravimetric analysis. The results showed that intercalation of dye molecules within the interlayer spaces of montmorillo...

A series of pyridinol-blocked isophorone isocyanates, based on pyridinol including 2-hydroxypyridine, 3-hydroxypyridine, and 4-hydroxypyridine, was synthesized and characterized by ¹H-NMR, 13C-NMR, and FTIR spectra. The deblocking temperature of blocked isocyanates was established by thermo-gravimetric analysis (TGA), differential scanning calorimetry (DSC), and the CO₂ evaluation method. The d...

The co–polymer (Poly-ClBN) of 1, 2 Di-ChloroBenzene and Naphthalene has been synthesised. The copolymer (Poly-ClBN) has been characterised by X Ray Diffraction (XRD) and UV spectroscopic method. Thermo Gravimetric analysis (DTA, DTG and TG) has been used for analysis of thermal stability of the copolymer.

Caffeine loaded magnetic nanoparticle was successfully synthesized and were characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDX), thermo gravimetric analysis (TGA), differential thermal analysis (DTA) and vibrating sample magnetometer (VSM). The resulting nanocom...
