15 صفحه اولPreparation and growth of SnS thin film deposited by spray pyrolysis technique
In this paper thin films of tin sulfide (SnS) were deposited on the glass substrates using spray pyrolysis method with the substrate temperatures in the range of 400–600℃, keeping the other deposition parameters constant. In this work the characteristic of SnS thin films investigated. The XRD pattern and optical transmittance of thin films also are discussed. With the change in concen...
متن کاملPyrolysis Kinetics of Physical Components of Wood and Wood-Polymers Using Isoconversion Method
Two hardwood species, namely red oak and yellow-poplar, were separated into their bark, sapwood and heartwood components. The samples were tested for calorific value, specific gravity, proximate analysis, mineral composition, chemical composition, ultimate analysis, and thermo-chemical decomposition behavior. In addition, the thermo-chemical decomposition behaviors of cellulose, xylan, and lign...
متن کاملEffect of Catalytic Pyrolysis Conditions Using Pulse Current Heating Method on Pyrolysis Products of Wood Biomass
The influence of catalysts on the compositions of char and pyrolysis oil obtained by pyrolysis of wood biomass with pulse current heating was studied. The effects of catalysts on product compositions were analyzed using GC-MS and TEM. The compositions of some aromatic compounds changed noticeably when using a metal oxide species as the catalyst. The coexistence or dissolution of amorphous carbo...
متن کاملStructural and electrical properties of In-doped vanadium oxide thin films prepared by spray pyrolysis
The In-doped vanadium pentoxide nanostructures with different doping levels including 0, 10, 20 and 30 at.% were prepared by the spray pyrolysis technique. The prepared thin films were characterized by the x-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD results revealed that the films were crystalline in tetragonal phase. Increasing the In-doping level made the structure...
