protein memories are novel technologies which use the hidden abilities of bacteria proteins and biological molecules in order to the electronic processes. four decades before baceriorhdopsin ( br) protein was extracted from the membrane of halobacerinum salina rum found in high salt water depositions after its original discovery in 1967. in this study, for immobilizing the protein a film has be...

in this study, silver nanoparticles were synthesized by chemical reduction method at different concentrations of ag colloid in the range of 500-16000 ppm. nanoparticles were deposited by spin coating method on pre-etched glass and si substrates. structural, optical and electrical properties of the samples were studied using scanning electron microscopy equipped with edax, uv-vis spectrophotomet...

We report on the effect of dopant concentration and substrate temperature on the electrical, optical and structural propertie of In-doped ZnO thin films via sol-gel method using spin coating technique to tackle the problem of high instrumental costs for film deposition. In particular, the effect of In dopant concentration will study at wide range (from 1% up to 10%) by using spin coating techni...

We report using doctor-blading to replace conventional spin coating for the deposition of the hole-transport material spiro-OMeTAD (2,20 ,7,70-tetrakis-(N,N-di-p-methoxyphenylamine)-9,90-spirobifluorene) in solid-state dye-sensitized solar cells. Doctor-blading is a roll-to-roll compatible, large-area coating technique, is capable of achieving the same spiro-OMeTAD pore filling fraction as spin...

Fabricating large single crystals with colloidal spheres as building blocks is challenging and of competitive interest. Spin-coating of colloids offers a robust technique, which is highly reproducible in obtaining colloidal crystals even at fast dynamical regimes; however, these crystals are intrinsically polycrystalline due to the axial symmetry of spin-coating. We report a new method that app...
