In this paper, local field enhancement factor (LFEF), refractive index and optical absorbance of nanocomposite are analyzed by varying core size, thickness of spacer and shell as well as dielectrics function of the spacer for the size of the nanocomposite with the range of 20 nm to 40 nm. For both quantum dot and quantum wire triple layered core shell nanostructure (CSNS), there are two resonances in visible and near/in infrared spectral region with high tunability. When the shell thickness increase and therefore increasing the gold content, the surface plasmon resonance (SPR) at the outer interface shifts to higher energy (blue-shifted) and at the inner interface weak peaks and shifted to lower energy (red-shifted). All of three optical properties, depend on core size, dielectrics and thickess of spacer, thickness of shell, shape of composite and filling factor. For the same thickness of spacer and shell of the two configurations, cylindrical triple layered CSNS less pronounced and shifted to infrared red (IR) spectral region which is recommendable for biological and photocatalysis application. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</p> 2019-01-12T09:36:09+00:00 ##submission.copyrightStatement## https://journals.aijr.in/index.php/anr/article/view/1482 Mechanical Characterization of Nanomaterial Reinforced Aluminum-based Hybrid Nanocomposites 2019-10-20T13:59:10+00:00 Girisha L girisha@pestrust.edu.in Malteshkumar Deshpande malteshkumar.d@pestrust.edu.in Gururaja Lakshman Naik gururajalnaik@gmail.com Mahanthesh M R mrm.maha@gmail.com <p>Nanostructures are viewed as definitive fiber materials as a reinforcement for matrices because of their impressive properties. Because of their phenomenal mechanical properties Carbon nanotubes (CNTs), graphene (GR), and nanodiamond (ND) have made an enormous proportion of intensity in research over the world. Multiwalled carbon nanotubes (MWCNTs), Graphene, and Nano Diamond were utilized as reinforcements for the current work. Nanostructures with their extraordinary strength, minute size, and high aspect ratio were used as reinforcements in commercial-purity Al matrix. These nanocomposites were manufactured by various different routes such as casting and powder metallurgy techniques. Both of these methods are helpful for the preparation of MWCNTs/Al nanocomposites. These nanocomposites were manufactured with various weight fractions of reinforcements and characterized for their mechanical properties and indicated improved properties in contrast with the base Al matrix. Al/MWCNT nanocomposites, Al/MWCNT/GR hybrid nanocomposites and Al/MWCNT/GR/ND hybrid nanocomposites samples were tested for their mechanical properties such as Young’s modulus, percentage elongation yield strength, and ultimate Strength. Mechanical characterization of these prepared composite samples demonstrated improved strength when compared with the casted samples.</p> 2019-05-25T09:46:27+00:00 ##submission.copyrightStatement## https://journals.aijr.in/index.php/anr/article/view/1959 Mechanistic Study of Antibacterial Properties of Chemically Synthesize Zinc Oxide Nanoparticles 2019-10-21T14:34:18+00:00 Abdur Rehman rehman392138@gmail.com Saira Ahmad saira.phd.sbs@pu.edu.pk Abdul Mateen a-mateen@hotmail.com Huma Qamar ad@cau.edu.cn Mudabber Ahmad ad@cau.edu.cn Ali Raza ad@cau.edu.cn Waqas Ali ad@cau.edu.cn Adnan Arshad ad@cau.edu.cn <p>Nanotechnology is the science, engineering and technology conducted at the scale that ranges between 1-100 nanometers. For the bio-application, evolution of nanotechnology is creating the concern of scientists towards the synthesis of nanoparticles. The nanoparticles have unique characteristics as compare to bulk materials. Zinc oxide (ZnO) is a matchless semiconductor and it has been under investigation due to its wide range of applications in various areas like biomedical, electronics, material science and optics. In the present work synthesis of ZnO nanoparticles was carried out by using simple chemical approach, Sol-gel method for being effective and inexpensive, by employing zinc acetate dehydrate Zn (CH<sub>3</sub>CO<sub>2</sub>)<sub>2</sub>.2H<sub>2</sub>O as a precursor and sodium hydroxide (NaOH) starch as a constant agent. The structural properties of resultant zinc oxide nanoparticles were investigated by X-ray diffraction (XRD) technique. The XRD data confirmed the hexagonal wurtzite structure of ZnO powder confirmed by JCPDS 36-1451 data. Particles size was calculated by Scherrer formula and calculated size was 30.14 nm. These nanoparticles were investigated for inhibition zone of bacterial strain <em>Escherichia coli</em>, a gram-negative microbe, at various concentrations of ZnO nanoparticles. Zinc oxide nanoparticles were very proficient for inhibition of growth of bacterial strain <em>E. coli</em>. The mechanism of ZnO NPs for antibacterial activity is release of reactive oxygen species which not only hydrolyze cell wall but cell membrane and cellular components as well providing a potential bactericidal effect.</p> 2019-10-21T14:34:18+00:00 ##submission.copyrightStatement## https://journals.aijr.in/index.php/anr/article/view/1218 Green Peptide–nanomaterials; A Friendly Healing Touch for Skin Wound Regeneration 2019-10-20T13:59:10+00:00 Debjani Nath nath_debjani@yahoo.co.in Pratyusha Banerjee bandyo.prat86@gmail.com Anugrah Ray anugrahray@yahoo.in Baishakhi Bairagi baisakhi91@yahoo.com <p>The complex phenomenon by which the body responds to any injury of skin or tissue is known as wound healing. A number of phases like exudative, proliferative, and extracellular matrix remodeling are orchestrated events to be occurred involving blood cells, parenchymal cells, and different soluble mediators. Different internal, as well as external factors, regulate the speed and quality of healing. The delay in wound healing process causes the chronic wound or scar formation. At the present moment, the upscale research for identification of agents causing accelerated healing is important. Moreover, the biocompatibility of the accelerators needs to be investigated. Recent biomedical researches for wound care target to provide antimicrobial protection as well as matrix scaffolding for quick repairing of the skin tissue. In recent studies with natural peptides have shown that they are important components in developing the nano-medicines for their usefulness and therapeutic efficiency. New therapeutic formulations can be developed using these natural peptides utilizing different nanoparticle delivery system. This review deals with the developmental study on efficient wound care system where the possible use of natural peptides in combination with nanomaterials has been explored. A trial has also been made on the findings made over the past few years on the use of peptides as tissue regenerating agents through effective wound healing pathway.</p> 2019-03-22T16:18:41+00:00 ##submission.copyrightStatement##
