Batteries are a major technological challenge in this new century as they are a key method to make use of energy efficiently. Nowadays Lithium-ion batteries (LIBs) appeared to be one of the most important energy storage technologies. Today’s Li-ion technology has conquered the portable electronic markets and still on the track of fast development. The success of lithium-ion technology will depend largely on the cost, safety, cycle life, energy, and power, which are in turn determined by the component materials used for its fabrication. Accordingly, this review focuses on the challenges of organic based materials and prospects associated with the electrode materials. Specifically, the issues associated with organic based batteries, advances and prospects are presented. This review aims to summarize the fundamentals of the polymer-based material for lithium-ion batteries (LIBs) and specifically highlight its recent major advancement in material design, challenges, performance and finally its prospects. We anticipate that this Review will inspire further improvement in organic electrolyte materials and the electrode for the battery as energy device storages. Some of these concepts, relying on new ways to prepare electrode materials by the use of eco-efficient processes, on the use of organic rather than inorganic materials in order to overcome environmental issues associated with their use. Organic electrodes are important for solid electrode batteries because they can make device cost-effective, allow flexibility, and can also enable the use of multivalent ions without the problems typically associated with inorganic compounds. https://www.ajnanomat.com/article_75266_bcb34341e933a6a6de21517e6f794b7c.pdf Polymer Lithium ion Battery performance eng Sami Publishing Company (SPC) Asian Journal of Nanosciences and Materials 2645-775X 2588-669X 2019-01-01 2 1 27 36 10.26655/ajnanomat.2019.1.2 75244 مقاله پژوهشی Parvin Gharbani [email protected] 1 Amir Mehalizadeh [email protected] 2 Department of Chemical Engineering, Ahar Branch, Islamic Azad University, Ahar, Iran Department of Chemical Engineering, Ahar Branch, Islamic Azad University, Ahar, Iran The zinc oxide nano sheets were prepared by zinc sulfate and sodium hydroxide via precipitated method and, then, calcinated at 300 oC. In order to have a reliable characterization of the synthesized ZnO nanosheets, FTIR, XRD, FESEM, XRF, TGA and Raman techniques were applied. The phase and purity of zinc oxide nanosheets were confirmed by XRD and XRF, respectively. FESEM results showed the morphology of zinc oxide and revealed that the size of the prepared powder is in the range of nanometer. TGA analysis revealed that there are two endothermic reactions which have occurred at 35-200oC and 300 - 400oC temperatures. Optical spectra indicated that the band gap of the prepared nanosheets transmitted a red shift. https://www.ajnanomat.com/article_75244_64471746e1887d547d94463473ee8b17.pdf Zinc oxide Synthesis Optical properties Nano Sheet eng Sami Publishing Company (SPC) Asian Journal of Nanosciences and Materials 2645-775X 2588-669X 2019-01-01 2 1 37 48 10.26655/ajnanomat.2019.1.3 73762 مقاله پژوهشی Soghra Fathalipour [email protected] 1 Mahdiye Ghanbarizadeh [email protected] 2 Department of Chemistry, Payame Noor University, PO Box 19395-3697 Tehran, Iran.

Obtainedcysteine-hydrogel (Chydrogel) having different functional groups could stabilize Ag NPs better than un-modified hydrogel due to the presence of disulfid bondings. First, obtained PAA hydrogel from radical polymerization was conjugated with cysteine-hydrochloride (Cys) through amidation reaction and then was used as a substrate and stabilization reagent for Ag ions. Ag ions were reduced on Chydrogel in the presence ofNaBH4 as reducing reagent. The resultant nanocomposite was well characterized by using UV–vis, FT-IR, XRD and SEM techniques. Furthermore, the resultant Ag NPs on the surface of Chydrogel showedhigh antibacterial behavior against Gram-negative E. coliand Gram-positive S. aureusdue to the high reaction of thiol-functions with the outer cell surface. https://www.ajnanomat.com/article_73762_575158cc3cf3fcd85ba3df0bc973b90a.pdf hydrogels Composites antibacterial inorganic materials Ag NPs eng Sami Publishing Company (SPC) Asian Journal of Nanosciences and Materials 2645-775X 2588-669X 2019-01-01 2 1 49 65 10.26655/ajnanomat.2019.1.4 75234 مقاله پژوهشی Fatemeh Houshmand [email protected] 1 Hamide Neckoudaria 2 Majid Baghdadi [email protected] 3 Computational Physical Sciences Research Laboratory, School of Nano-Science, Institute for Research in Fundamental Sciences (IPM), P.O.

In this system a component is, MX (3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone) a mutagenic halogenated disinfection by products which present in drinking water. And, chitosan is an eco-friendly nano-adsorbent to remove oils, grease, heavy metals and the fine particulate matter from water solution. Electronic and structural properties of chitosan during functionalization by metal were studied by density functional theory (DFT) calculations. Isolated and functionalized chitosan were optimized and their properties were evaluated. The results indicated that the properties of linking sites detect the most significant effects of functionalization process.<br /> Degradation efficiency of MX and its analogous in water solvent and also the possibility of absorption of MX by chitosan nanoparticles in aqueous solution were studied via different level of theory. https://www.ajnanomat.com/article_75234_f855570545c3164d7d44107a9f55621d.pdf Halogenated furanone (MX) MX analogous Disinfection Byproducts Chitosan Density functional theory eng Sami Publishing Company (SPC) Asian Journal of Nanosciences and Materials 2645-775X 2588-669X 2019-01-01 2 1 66 91 10.26655/ajnanomat.2019.1.5 79350 Somayeh Deljoo [email protected] 1 Navid Rabiee [email protected] 2 Mohammad Rabiee [email protected] 3 Department of plant sciences, Faculty of natural sciences, University of Tabriz, Tabriz, Iran Department of Chemistry, Shahid Beheshti University, Tehran, Iran 1. Biomaterials Group, Faculty of Biomedical Engineering, Amirkabir University of Technology, Tehran, Iran Extensive studies on curcumin has improved that it has certain therapeutic role for different kinds of diseases such as cancer. Regardless of its positive features, its application is hampered by its low water solubility, bioavailability, and low cellular uptake. During last year’s several ways have been developed to protect curcumin from degradation and increase its capability to targeting unhealthy cells. The progress in nanotechnology encouraged nanotechnologists to formulate nanoparticles encapsulating curcumin, such as polymer nanoparticles, solid nanoparticles, liposome/lipid nanoparticles, micelles, dendrimers, polymer conjugates, etc. to enhance sustained release of curcumin at target cells and to improve curcumin bioavailability. Nowadays newer formulations of nanoparticles as called Hybrid nanoparticles are designed in order to efficient and specific targeting of curcumin that result in improved therapeutic efficacy of curcumin with high biocompatibility with the aid of aptamers, folic acid, chitosan coated halloysite loaded with curcumin-Au hybrid nanoparticle and so on. This review describes a number of hybrid nanoparticles formulated and their efficacy in specific targeting to cancerous cells. https://www.ajnanomat.com/article_79350_ab1397dcb9ea1dfb47f4db92ec6bbbc8.pdf curcumin hybrid nanoparticles Drug delivery system eng Sami Publishing Company (SPC) Asian Journal of Nanosciences and Materials 2645-775X 2588-669X 2019-01-01 2 1 92 98 10.26655/ajnanomat.2019.1.6 79380 Alagappan Subramaniyan [email protected] 1 Veeraiah Veeraganesh [email protected] 2 Department of Physics,Thiagarajar College of Engineering,Madurai 625015,India Department of Physics,Thiagarajar College of Engineering,Madurai 625015,India Nanocomposites are novel materials which are yet to be explored and utilised to its complete potential. Nanocomposites can be tailored by the volume fraction of the matrix, fibre and also by the size and shape of the nanophase material in the composite. Preparing nanocomposite with a desired shape and size remains a challenge. In the present work nanocomposites of SnO–Fe2O3.are prepared by a sol gel route with Ferric chloride and Tin chloride as precursors.
