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 ...

Abstract Battery‐type supercapacitors have drawn significant attention due to their high charge storage ability resulted from the combined surface and intercalation redox phenomenon. In this regard, nickel chalcogenides are expected deliver specific capacity accompanied by dominant battery‐type supercapacitor features. Herein, we developed a facile one step solvothermal route prepare pure phase...

A supercapacitor, also called an ultracapacitor, is a high-capacity capacitor with capacitance value much higher than other capacitors, but lower voltage limits, that bridges the gap between electrolytic capacitors and rechargeable batteries. To synthesize graphene oxide/polypyrrole (GO/PPy) composite, sacrificial template needed such as MnO2 through polymerization of pyrrole in presence GO use...

Plasmonic nanostructures have been shown to act as optical antennas that enhance optical devices. This study focuses on computational electromagnetic (CEM) analysis of GaAs photodetectors with gold interdigital electrodes. Experiments have shown that the photoresponse of the devices depend greatly on the electrode spacing and the polarization of the incident light. Smaller electrode spacing and...

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...
