In this paper, the temperature dependence of some characteristics of cylindrical gate-all-around Si nanowire field effect transistor (GAA-Si-NWFET) is investigated to representing the temperature nano-sensor structures and improving their performance. Firstly, we calculate the temperature sensitivity of drain-source current versus the gate-source voltage of GAA-Si-NWFET to propose the temperatu...

Recent developments in shape-controlled synthesis of metallic nano-particles present a promising path for precisely tuning chemical activity, selectivity, and stability of nano-materials. While previous studies have highlighted the macroscopic description of synthesis processes, there is less understanding as to whether individual atomic-scale processes possess any significant role in controlli...

This paper is focused on the template-free synthesis of nanosized ferric oxide (nano-Fe(2)O(3)) and its application in quartz crystal microbalance (QCM) resonators to detect dimethyl methylphosphonate (DMMP), a simulant of Sarin. The X-ray diffraction (XRD) patterns confirm that the synthesized samples are made of Fe(2)O(3) and the scanning electron microscopy (SEM) pictures show that the sampl...

Treating cancer tumors is a main goal of cancer research. The author of this paper identifies a new manner to treat cancer tumors more effectively using a recommended architecture of a nanorobot called CANBOT. It contains a number of nano-components: an actuator, temperature sensor, chemical sensor, and microcontroller. CANBOT starts its role by moving toward the tumor cells using the actuator....

Pristine complex quaternary hydride (LiBH4/2LiNH2) and its destabilized counterpart (LiBH4/2LiNH2/nanoMgH2) have recently shown promising reversible hydrogen storage capacity under moderate operating conditions. The destabilization of complex hydride via nanocrystalline MgH2 apparently lowers the thermodynamic heat values and thus enhances the reversible hydrogen storage behavior at moderate te...

a  facile  effective  stirring  aging  at  room  temperature  prior  to  conventional  hydrothermal treatment was employed in the template-free synthesis of micro- and nano-crystalline sodalites with  two  different  initial  gel  compositions.  the  effect  of  initial  si/al  molar  ratio,  naoh concentration and stirring aging time were investigated on the morphology and particle size of the...

in this paper, we have studied the electrical properties of the randomly distributed metallic (co and fe) nano/ micro wires on silicon substrate. deposition was carried out potentiostatically into the pores of the track-etch polycarbonate membrane spin coated onto the si substrate. spin coated films were irradiated with 150mev ni (+11) ions at a fluence of 8e7 ions/cm2, followed by uv irradiati...

nano-zeolite coapo-5 as a member of afi family, was synthesized via a hydrothermal treatment, and structurally characterized using x-ray diffraction (xrd), scanning electron microscope (sem), and energy dispersive x-ray analysis (edax). the effects of crystallization temperature and time on the structure of these powder products were studied. xrd patterns of the synthesized powders revealed a h...

We investigate the PL characteristics of the equivalent-size controlled Si-QDs by employing the nano-porous AAO membrane as the template for growing Si-rich SiOx nano-rods to achieve the spatially confined synthesis of Si-QD. The ultra-bright PL can be emitted from the SiOx nano-rod in nano-porous AAO membrane. In addition, we preliminarily demonstrate the in-situ high-temperature synthesis of ...

An efficient and environmentally benign   method for the synthesis of aryl iodides have been developed by diazotization of aromatic amines with NaNO2 and nanosilica periodic acid (nano-SPIA) as a green catalyst via grinding followed by a sandmeyer iodination by KI under solvent-free conditions at room temperature. The ensuing aryl diazonium salts supported on nano-SPIA were sufficiently stable ...
