Nano particles may be more useful in comparison to bulk materials because they can pass the cell membrane of crops because of their general size. Nano-silicon or SiO2 is one of the major and frequently used engineered oxide nano particles in deferent fields. Quick germination of cultivated seeds and good seedling establishment are key factors to lentil production under salinity stress soil acro...

PURPOSE The objective of the present investigation was to evaluate the morphologic characteristics of self-assemblies of diamond (nano-D), silver (nano-Ag), gold (nano-Au), and platinum (nano-Pt) nanoparticles with Staphylococcus aureus (bacteria) and Candida albicans (fungi), to determine the possibility of constructing microorganism-nanoparticle vehicles. METHODS Hydrocolloids of individual...

A self aligned nano scale gap between multiple metal layers has been fabricated using a newly developed technique of controlled undercut and metallization (CUM), and applied for the assembly of an individual carbon nanotube (CNT). The new method enables conventional optical lithography to fabricate nano-gap electrodes and self aligned patterns with nano scale precision. Individual CNTs were ass...

In the current paper, finite element method is employed for numerical simulations and the study of influential parameters on elastic modulus of polymer-matrix nano-composites. Effects of different key parameters including particle elastic modulus, interphase elastic modulus, matrix elastic modulus, interphase thickness and particle volume fraction on total elastic modulus of nano-composite mate...

in this research, al-ni particle composite strips are formed by accumulative roll bonding (arb) process using al strips and ni powder. the rule of arb cycles and volume percentage (vol%) of ni powder on the microstructure, wear resistance and mechanical properties of the formed composites are investigated. according to the tensile test results, the yield stress and tensile strengths of the al -...

Experimental results obtained for Pd/PdO/ZrO2 nano-composite samples are summarized and the underlying physics is discussed. Arata-Zhang’s May 2008 excess heat result was replicated quantitatively. Using Pd/PdO/ZrO2 powders (produced by Santoku Co., Kobe Japan), we obtained: 1) D-gas charge in the first phase (zero pressure interval) gave 20~90% excess heat than H-gas charge. 2) In the second p...

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...

Pattern creating with nano-particle is one of the best application methods in nano-scale that it will be used for new pattern creating and make micro/nano-electromechanical System (MEMS/NEMS) in future. Particle swarm optimization algorithm is one of evolutionary computation techniques and the optimization method based on population and ant algorithm, optimization algorithm is modeled based on ...

Plasmonics based sensors have been a prominent area of research. Plasmonics based sensors are widely used in bio sensing and many other applications. The basic mechanism in which these sensors operate is that there are metal nano particles that are separated by a very small distance between them. The dimensions of these nano particles is much smaller than the incident light [1]. For sensing pur...
