The trend of integrating nanostructure to elevate the MEMS capability is becoming a trend in microelectronic sensor field. Critical functional element of sensors in the scale of 10 -6 and 10 -9 m in any dimension being incorporated with appropriate nanostructure as part of the sensor systems through two basic approaches: topdown and bottom up. The techniques and methods of both approaches will ...

The hexagonal zinc oxide coated nickel (Ni/ZnO) nanostructure photocatalyst has successfully been prepared by the reduction of nickel chloride hexahydrate using hydrazine hydrate through the solvothermal process at 140 °C followed by surface modification of the product by the reflux method at 110 °C for 1 h. The X-ray diffraction (XRD) pattern showed that the 'as prepared' sample consists of fa...

The study describes chitosan membrane platform modified with nanostructure pattern which using nanotechnology to fabricate. The cell-substrate interaction between neuro-2a neuroblasts cell lines and chitosan membrane (flat, nanostructure and nanostructure pattern types) was investigated. The adhered morphology of neuro-2a cells depends on the topography of chitosan surface. We have found that n...

Silicon nanostructure surface fabricated from metal-assisted etching have been demonstrated as high sensitivity matrix-free laser desorption/ionization mass spectrometry chip. The silicon nanostructure morphology was found to have direct effect to the mass spectrometry ionization efficiency. Creation of different silicon nanostructure morphologies by changing the metal thickness, etching time a...

Flower-like ZnO nanostructures were synthesized by decomposing Zn(OH)2 in 1,4- butanediol at 105 °C for 36 h. Size of flower-like ZnO nanostructure can be controlled by pH of the aqueous solution. In the preparation of flower-like ZnO nanostructure, zinc nitrate was used as a precursor. The morphology and microstructure of flower-like ZnO nanostructure have been characterized by scanning electr...

terms and conditions of current drinking water quality standards, including reducing the maximum arsenic concentration from 50 μgl-1 to 10 μgl-1 and predicted stricter standards in future, reveals the necessity for development of new technologies. this study aimed to prepare and evaluate a new nanocomposite membrane using graphene oxide (go) thin layer to remove arsenic (v) from water. to fabri...

in this study, pyrite was produced by hydrothermal precipitation from the reaction between feso4 and na2s2o3 at high pressure and high temperature in a stirred reactor. the solid product was purified by means of solvent extraction to remove sulfur. powder was characterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and thermal analyses. results indicated that pyrite was prod...

in this research, mechanical alloying was used to produce ti-50al, ti-45al-5cr and ti-45al-5w (at%) alloys. the effect of ternary addition (cr and w) on microstructure and production efficiency of tial alloy were investigated. alloying was performed in a planetary mill and the milling time varying from 5 to 70h. the structural evaluation in these powders was done by x-ray diffraction (xrd) tech...

in this work, the synthesis of porous structure of cadmium oxide with multilayered sheet-like morphology in nano-meter size using adipic acid as soft template by solvothermal/thermal decomposition process is reported. chemical analyses exhibited that the formation of porous sheet-like structure is originated from bidentate coordination mode of adipate units to cd-center. it was found that the c...

in this paper, a nanostructured modified electrode was fabricated by incorporating of 2,2′-[1,9-nonanediylbis(nitriloethylidyne)]-bis-hydroquinone (nnh) as a newly synthesized modifier and tio2 nanoparticles to the carbon paste (mtcpe) and then was used for the electroanalysis of epinephrine (ep). the electrochemical studies were carried out by using cyclic voltammetry, chronoamperometry and di...
