AIM Biomimetic nano-assembly formation offers a convenient and bio friendly approach to fabricate complex structures from simple components with sub-nanometer precision. Recently, biomimetic (employing microorganism/plants) synthesis of metal and inorganic materials nano-particles has emerged as a simple and viable strategy. In the present study, we have extended biological synthesis of nano-pa...

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...

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...

Tungsten carbide cobalt (WC-Co) has been recognized as a workplace inhalation hazard in the manufacturing, mining and drilling industries by the National Institute of Occupational Safety and Health. Exposure to WC-Co is known to cause "hard metal lung disease" but the relationship between exposure, toxicity and development of disease remain poorly understood. To better understand this relations...

Nano- and microscale motors powered by catalytic reactions exhibit collective behavior such as swarming, predator-prey interactions, and chemotaxis that resemble those of biological microorganisms. A quantitative understanding of the catalytically generated forces between particles that lead to these behaviors has so far been lacking. Observations and numerical simulations of pairwise interacti...

Wound healing still remains a challenging problem that is why wound management is necessary. Metal nano particle like, gold and silver shows bacteriostatic and bactericidal activities. Biomaterials like chitosan and collagen play an important role as wound dressing materials. It stimulates wound healing by fibro genesis and increases the development of skin .When we embed any biomaterial with n...

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...
