Nano-structured copper oxides were successfully prepared through direct calcination of 1D ladderlike metal-organic framework [Cu2(btec)(2,2'-bipy)2]∞, (btec = 1,2,4,5-benzenetetracarboxylate and 2,2'-bipy = 2,2'-bipyridine) and porous coordination polymer [Cu(BDC)(bipy)](BDCH2), (BDC = 1,4-benzenedicarboxylate; bipy = 4,4'-bipyridine). The nano-structure of the as-synthesized samples are charac...

The work presents results of the characterization of dust collected in ASDEX Upgrade, with the special emphasis on size, morphology, structure and composition of the dust particles. The dust particles were collected after 2009 campaign using the filtered vacuum technique. The structure and composition of the particles were examined by scanning electron microscopy (SEM) combined with energy-disp...

   Nickel-molybdenum oxidebimetallic nanoparticles were synthesized in ethylene glycol using the microwave irradiation technique. According to the results, successive reduction of nickel and molybdenum ions, followed by thermal treatment of obtained nanoparticles led to formation of core-shell structured nickel-molybdenum oxide nanoparticles. According to the results, the thickness of the s...

SnCl4/nano-sawdust was prepared as a carbohydrate-based catalyst containing of tin bearing cellulose units. The catalyst was characterized by X-ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM) and energy dispersive X-ray spectroscopy (EDS). The catalyst was applied successfully as a readily available, inexpensive, biodeg...

The reaction of nano-cellulose and antimony pentachloridein dichloromethane gave nano-cellulose-SbCl5. Also nano-cellulose-SbCl5 has beencharacterized by energy dispersive X-ray spectroscopy(EDX), scanning electron microscopy (SEM)and Fourier transform infrared spectroscopy(FTIR).Nano-cellulose-SbCl5has been applied as a nano-catalyst for synthesis of pyrano[2,3-d]pyrimidines from the simple on...

Thin films of indium doped zinc sulfide (ZnS) for different indium (In) concentrations (x=0.0 - 0.8) were deposited onto glass substrate by spray pyrolysis method at 523K temperature. Aqueous solution of zinc acetate, indium chloride and thiorea were used to deposit the In-Zn-S film. The deposited thin films were characterized by Energy dispersive X-ray (EDX), Scanning electron microscopy (SEM)...

the photocatalytic coatings were prepared via incorporating the modified titania nanoparticles into epoxy-based inorganic-organic hybrid coatings. titania nanoparticles were first synthesized from tetra-n-butyl titanate using sol-gel methods by two different calcination treatments, i.e., in mild condition (80°c) and 500°c. the formed anatase nanoparticles were further modified as titania-silica...

The present study investigated the role of alloy microstructure and surface roughness on wear and friction behavior of leaded and unleaded tin bronzes. Ball-on-disk experiments were carried out under dry conditions with steel balls sliding against bronze disks. Scanning electron microscopy (SEM), energy dispersive electron microscopy (EDX), x-ray photoelectron spectroscopy (XPS) and Auger elect...

an aqueous extract of pimpinella anisum was used for green synthesis of silver nanoparticles by bio reduction of an aqueous solution of silver nitrate. silver nanoparticles were characterized by uv–vis spectrometry, fourier transform infrared spectroscopy (ftir), x-ray diffraction (xrd) analysis, scanning electron microscopy (sem) and energy-dispersive x-ray analysis (edax). the increase in abs...
