this paper is the first multi-scale characterization of the fluidize-dried gum extracted from the fresh fruits of the plant abelmoschus esculentus. it describes the physical, thermal, sorptional and functional properties of this natural gum. elemental analysis, scanning electron microscopy (sem), particle size analysis, x-ray powder diffraction (xprd), thermo-gravimetric analysis (tga), differe...

this study focuses on achieving high stiffness/strength and good fr characteristic of nylon 66/mca/nc nanocomposites, prepared via melt compounding by twin screw extruder. a synergistic effect of flame retardant systems based on melamine cyanurate and zinc borate on the flammability and mechanical behaviours of crysnanoclay reinforced nylon 66 nanocomposites have been reported. mechanical test ...

b1-xlaxfeo3 (x = 0.0, 0.025) crystallites were prepared by chemical solution route. xrd analysis confirmed the phase formation of the materials. thermal characterization was done by dsc-tga to confirm crystallization and thermal behavior for phase development. morphological studies by fesem showed the agglomerated nature of the ferrite and edx analysis confirmed the degree of doping. ftir studi...

In current study, the synthesis and characterization of novel thermally stable polyimides (PIs) containing an 1,3,4-oxadiazole moiety based on a diamine, i.e. 2,5-bis(3-amino-4-methyl benzene)-1,3,4-oxadiazole (BAMO), have been reported. The polymers were characterized using FT-IR and elemental analysis (CHN). Thermal and mechanical behaviours of the prepared PIs were studied by thermo-gravimet...

Electrical methods for thermal characterization, like 3ω method, micro-bridge method and TET method have been widely used in the thermal property measurement, while always been limited by the electrical conductance of samples or other temperature dependent thermal resistors. As an optical method, Raman thermometry has been developed and broadly applied in thermal characterization in recent year...

in the present work, we report the synthesis of binary nano metal oxides such as zinc /copper oxide via novel dry synthetic methods such as thermal decomposition of oxalate precursor. the synthesis route involves facile solid-phase mechanochemical activation of a physical mixture of simple copper/zinc salts and oxalic acid, followed by calcination of the as-ground oxalate precursors at 450◦c. x...

this study is devoted to the morphological, chemical and physical characterization of raw material of the fruit of luffa cylindrica. by microscopic analysis, it can be observed that the fruit is composed of an assembly of dependent cords, where four parts are differentiated: external, internal wall, core and bond. each cord consists of hollow and flexible cylindrical fibers.the external part is...

the effects of different sources of carbon, nitrogen and some of trace elements on cultivation of bacillus thuringiensis h14 were studied. glucose, glycerol, sodium acetate, (nh4)2so4, corn steep liquor, yeast extract, hydrolyzed casein, ca2+, mg2+ and mn2+ were the main parameters evaluated by plackett-burman statistical method. all elements have insignificant effect on germination while spore...

in this research nanoparticles of nickel (ii) chloride were synthesized and characterized using fourier transform infrared (ft-ir) spectra. nanoparticles of nickel (ii) chloride were prepared by using of ball mill device. a ball mill is one kind of grinding machine, and it is a device in which media balls and solid materials (the materials to be ground) are placed in a container. in the researc...
