physical vapor deposition, electron beam evaporation, chemical vapor deposition, boil deposition, solvo-thermal, thermal evaporation, dip coating, electrochemi- cal, wet impregnation, sol-gel process, hydrothermal, and pulsed laser deposition method among others [6,8]. Of all these meth- ods, the sol-gel technique appears to be the most promising and simple to use due to the production of... a sol-gel solution of 8% polyacrylonitrile (PAN)/dimethylformamide (DMF)/TiCl₄. The influence of the pyrolysis temperature and holding time on the morphological characteristics, particle sizes and surface area of the prepared catalyst was investigated. The prepared catalysts were characterized by several analytical methods: high resolution scanning electron microscopy (HRSEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), and X-ray photoelectron... -

a way to solve these problems using the sol-gel method. Unlike the high- ly exothermic combustion process, the sol-gel method is easy and simple to control and suitable for scale-up to the kilogram level [18]. In general, the sol-gel process involves the evolution of inorganic networks through formation of a colloidal suspen- sion (sol) and gelation of the sol to form a three dimensional... -

high purity products to friable agglomerates of very fine particulates. The purpose of the present study was to evaluate porous HAp, the powders of which were prepared by a novel aqueous solution combustion technique, as a bone substitute in healing bone defects. Materials and Methods Synthesis of nano-crystalline HAp by an aqueous solution combustion method Calcium nitrate tetrahydrate (S.D.... a novel aqueous solution combustion technique, as a bone substitute in healing bone defects in vivo, as assessed by radiologic and histopathologic methods, oxytetracycline labeling, and angiogenic features in Bengal goat. Bone defects were created in the diaphysis of the radius and either not filled (group I) or filled with a HAp strut (group II). The radiologic study in group II showed the presence of unabsorbed implants which acted as a scaffold for new bone growth across the defect, and the... -

to combustion of as-spun PAN fiber by heat and oxygen [18]. These three zones of the TiO 2-AC fibers prepared are also shown in the Fig. 5. From the results of Fig. 5(a), the water evaporation of the electrospun PAN fiber mainly occurred in the zone II (temperature<298 oC) and almost no thermal decomposition of PAN was taken place. Due to inner molecular cyclizing, inter-molecular cross-linking,... -

for production on a commercial scale, such as the radio-frequency-plasma technique or the arc plasma technique. Even commercial production has the same drawbacks as the laser irradiation method. These above men- tioned methods are referred as the I-G method for synthesis of fullerene. The I-G method is a combustion-based process for the synthesis of fullerenes, and it results in >98% pure... The element carbon has been used as a source of energy for the past few hundred years, and now in this era of technology, carbon has played a significant and very prominent role in almost all fields of science and technology. So as an honour to this marvellous element, we humans should know about its various forms of existence. In this review article, we shed light on all possible carbon-allotropes; similarities in their synthesis techniques and the starting materials; their wide range of... -

exhibited better effciency in fre retardancy compared to the MWCNT buckypaper. This was due to the smaller median pore size of the MWCNT-g-POSS hybrid buckypaper and char formation during combustion, which could effectively limit the heat and mass transfer and the diffusion of fammable gases and therefore slow down the combustion and degradation of the resin. 5. Superhydrophobicity on... Materials with appropriate surface roughness and low surface energy can form superhydrophobic surfaces, displaying water contact angles greater than 150°. Superhydrophobic carbon-based materials are particularly interesting due to their exceptional physicochemical properties. This review discusses the various techniques used to produce superhydrophobic carbon-based materials such as carbon fibers, carbon nanotubes, graphene, amorphous carbons, etc. Recent advances in emerging fields such as... -
