In this paper, we present a summary of the main properties and difficulties when performing the characterization, the measurement, the identification and the control of systems dedicated to the micro/nano-world.

Hydroxyapatite (HA)ynano-zirconia composite coatings were successfully produced through high velocity oxy-fuel (HVOF) spraying of radio frequency (RF) plasma synthesized powders. Microstructure characterization and morphology analysis on the nano-structured coatings were conducted using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffractometry (XRD), and d...

The fisheries and livestock sectors capture the highest share of protein-rich animal food and demonstrate accelerated growth as an agriculture subsidiary. Environmental pollution, climate change, as well as pathogenic invasions exert increasing stress impacts that lead the productivity momentum at a crossroads. Oxidative stress is the most common form of stress phenomenon responsible for the re...

In this paper, we study the effect of single Boron/Nitrogen impurityatom on electronic properties of a silicene nano flake. Our calculations are basedon density functional theory by using Gaussian package. Here, one Si atom insilicene nano flake substitutes with a Boron/Nitrogen atom. The results show thatsubstitution of one Si atom with single Boron/Nitrogen atom increases distanceof impurity ...

Plasmonic, metallic nanostructures have attracted much interest for their ability to manipulate light on a subwavelength scale and related applications in various fields. In this work, parabola-like gold nanobowtie (PGNB) sapphire substrate was designed as nano-cavity confining waves nanoscale gap region. The near-field optical properties of the innovative PGNB structure were studied comprehens...

Nano machines can be connected together in a nano network. Molecular communication provides the most practical way in which nano machines can communicate with each other. This paper presents a review of pioneering research work in mathematical modelling and channel characterization of molecular communication for nano networks. It is reported that propagation of molecules can be modelled as dete...

Superior first-cycle Coulomb efficiency (above 80%) is displayed by filter paper-derived micro-nano structure hard carbon, and it delivers a high reversible capacity of 286 mAh g-1 after 100 cycles as the anode for Na-ion battery at 20 mA g-1. These advantageous performance characteristics are attributed to the unique micro-nano structure, which reduced the first irreversible capacity loss by l...

background: many attempts have been performed and continued for improvement of dental amalgam properties during last decades. the aim of present research was fabrication and characterization of amalgam/titania nano composite and evaluation of its corrosion behavior. materials and methods: in this experimental research, nano particles of titania were added to initial amalgam alloy powder and the...

Introduction Scaling and integration of complementary metaloxide-semiconductor devices have made great development in the pursuit of higher performance and lower power consumption. Elemental devices of field effect transistors have been going through a transition from planar to three-dimensional structures for overcoming the physical limitation of thickness for the gate insulator. However, due ...

To closely analyze the dislocation structure evolution during nano-indentation, a multi-scale discrete dislocation plasticity code is modified to include nano-indentation loading. This code couples two length scales, discrete dislocation dynamics and continuum finite element analysis and has been successfully applied to analyze various problems in mechanics and materials science. Description of...
