Manipulating structure, defects and composition of a material at the atomic scale for enhancing its physical or mechanical properties is referred to as nanostructuring. Here, by combining advanced microscopy techniques, we unveil how formation of highly regular nano-arrays of nanoparticles doubles the strength of an Fe-based alloy, doped with Ti, Mo, and V, from 500 MPa to 1 GPa, upon prolonged...

Monolayer transition metal dichalcogenides MX2 (M = Mo, W; X = S) exhibit remarkable electronic and optical properties, making them candidates for application within flexible nano-optoelectronics. The ability to achieve a high optical signal, while quantitatively monitoring strain in real-time is the key requirement for applications in flexible sensing and photonics devices. Surface-enhanced Ra...

In this project, versatile processing techniques are established for improving the internal and external quantum efficiencies of Si MOSLEDs via the detuning the size and density of high-aspect-ration Si nano-rod and buried Si nanospheres. A rapid thermal annealing synthesis of metallic nanodot array is realized to control the size and density control of metallic nanodots as an etching mask for ...

BACKGROUND Carcinogenicity of nickel compounds has been well documented. However, the carcinogenic effect of metallic nickel is still unclear. The present study investigates metallic nickel nano- and fine particle-induced apoptosis and the signal pathways involved in this process in JB6 cells. The data obtained from this study will be of benefit for elucidating the pathological and carcinogenic...

Nickel based nano particles are metallic Ni and NiO. These materials find wide utility in various fields in view of their high surface potentials, surface area, semi conducting nature, reduction and complexing tendencies. The present review is mainly aimed at the investigations made in using these nano nickel particles as adsorbents in purifying water. The synthesis of nano particles of Ni/ NiO...

There has been a significant interest on plasmonics in a metallic structure with very narrow gaps for studies of nanophotonics. However, little attention has been paid to the behavior of surface plasmons (SPs) in quasi-continuous metallic structures. This study observes and analyzes intermediate characteristics between propagating SPs (PSPs) and localized SPs (LSPs) in a quasi-continuous metall...

In this paper, we analyzed the influence of changing the material of electrodes on the transport properties of single junction comprising GNR (Graphene Nano Ribbon) stringed to two semi-infinite electrodes using semi empirical model. The investigation of electron transport through GNR was accomplished by linking it to different metallic electrodes (Pt, Au and Ag) under different bias voltages w...

nowdays,  iron  nanoparticles  due  to  their  unique  characteristics  are used  in  all  of  sciences  and  technology.  these  nano  particles  due  to their  electrical, magnetic,  optical  and  catalytic  properties  and  having high  area  and  activity  that  is  promped  by  their  small  size  and most importantly  many  scientists  from  the  entire  world  are  interested  in their  ...

Metallic nanoparticles can exhibit very large optical extinction in the visible spectrum due to localized surface plasmon resonance. Spherical plasmonic nanoparticles have been the subject of numerous studies in recent years due to the fact that the scattering response of spheres can be analytically evaluated using Mie theory. However a major disadvantage of metallic spherical nanoparticles is ...
