The reaction is performed in the presence of ascorbic acid as a reducing agent and polyvinyl pyrrolidone as capping agent via four different procedures: (1) mixture of 90% HAuCl4 and 10% CuSO4.5H2O precursors, (2) mixture of 75% HAuCl4 and 25% CuSO4.5H2O precursors, (3) mixture of 50% HAuCl4 and 50% CuSO4.5H2O precursors (4) mixture of 25% HAuCl4 and 75% CuSO4.5H2O precursors. Effect of different percentages of Cu on Au nanoparticles has been analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM with EDAX analysis), DRS UV-Vis, and Fourier transform IR spectra (FTIR) analysis. X-ray diffraction (XRD) analysis revealed that the nanoparticles are of cubic structure without an impure phase. The successful doping of the Cu into the Au host was evident by XRD line shiftings. The increasing percentage of copper leads to the decreasing grain size. With the increase of Cu2+ to Au3+ ratio in the Cu2+/Au3+ mixed solution (> 50% Cu), XRD lines show no shifting. The average crystal sizes of the particles at room temperature were less than 9.9 nm. The surface plasmon resonance peak shifts from 380 to 340 nm, party due to the change in particle size. SEM images show a spherical shape and the size of nanoparticles becomes smaller with increasing the percentage of copper. Moreover, in the molar ratio of Cu2+/Au3+ = 75/25 (>50% Cu), mixture of spherical and trigonal nanoparticles were prepared. Fourier transform infrared spectroscopy (FT-IR) showed the coordination and conjugation nanoparticles with N and O atoms of C-N and C=O bonds.http://www.nanochemres.org/article_16668_1557178a2c1f6400137d604a8604c5e4.pdfIranian Chemical SocietyNanochemistry Research2538-42791220160701A New Nano-Chitosan Irrigant with Superior Smear Layer Removal and Penetration1501563408810.7508/ncr.2016.02.002ENMohammad KassaeeDepartment of Chemistry, Collage of Sciences, Tarbiat Modares University, Tehran, IranShabnam HosseiniDepartment of Chemistry, Collage of Sciences, Tarbiat Modares University, Tehran, IranS.Hossein ElahiDepartment of Mechanical Engineering, Arak University of Technology, Arak, IranBehnam BolhariDepartment of Endodontics, School of Dentistry, Tehran University of Medical Science, Tehran, IranJournal Article20150530Our primary objective was to measure root canal penetrations of aqueous antibacterial nano-chitosan (Nano-CS), for the first time. The second objective was to compare and contrast such penetrations to those of chitosan (CS) itself, as well as sodium hypochlorite (NaOCl), chlorhexidine (CHX) and ethylenediamintetraacetic acid (EDTA), at the routinely used concentrations. Molar roots were split longitudinally by a rotary diamond saw. Nano-CS was made by dissolving CS in acetic acid and adding tripolyphosphate (TPP), followed by a freeze-drying process. Dentin penetrations are estimated through measurements of sessile contact angles. Penetrations of the probed irrigants were assessed as inverse functions of their sessile contact angles. Accordingly, all Nano-CS solutions showed smaller sessile angles compared to those of NaOCl, CS, and EDTA samples. Hence, Nano-CS appeared to be a superior irrigant for demonstrating a higher penetration than the latter three. It fell only behind CHX, yet, the superb chelating ability of Nano-CS enabled it to remove smear layer to a larger extend than all of our other irrigants including CHX. Nano-CS could be considered as a new irrigant. Higher penetration was its main advantage over CS, and commercial NaOCl, and EDTA. This was verified by the smaller sessile contact angle of Nano-CS. Anticipated chelating effect of Nano-CS could anchor more efficient removal of smear layer. This was another advantage of Nano-CS over other irrigants including CHX. Other advantages of Nano-CS included its reported biocompatibility, biodegradability and antibacterial effects. Commercialization of Nano-CS was deemed in the near horizon.http://www.nanochemres.org/article_34088_fd8c9139c9dcdaee9e88f93e7d90e8c7.pdfIranian Chemical SocietyNanochemistry Research2538-42791220160701Synthesis and Characterization of a Novel Nanosilica Supported Bipyridinium Chloride Nanocomposite and its Application as a Basic Catalyst in the One-pot Preparation of Tetrahydrobenzo[b]pyran, Dihydropyrano[3,2-c]chromene and Dihydropyrano[4,3-b]pyran Derivatives1571651761010.7508/ncr.2016.02.003ENAli Reza KiasatChemistry Department, Faculty of Sciences, Shahid Chamran University of Ahvaz, Ahvaz, IranSheida HamidChemistry Department, Faculty of Sciences, Shahid Chamran University of Ahvaz, Ahvaz, IranSeyyed Jafar SaghanezhadACECR-Production Technology Research Institute, Ahvaz, IranJournal Article20151223A novel rice-husk-silica supported n-propyl bipyridinium chloride (RHPrBPCl) has been prepared.

Among six magnetically recoverable catalytic systems denoted as [γ-Fe2O3@HAp-MII], the catalyst in which M designated as Fe(II) showed the best efficiency as well as regio-selectivity in amination of oxiranes under an ambient reaction condition. A wide variety of aromatic and aliphatic amines were reacted with epoxides using magnetically separable iron catalyst to give the corresponding amino alcohols in excellent yields and selectivities in water as solvent at room temperature. In addition, recovery of the catalyst was successfully carried out in subsequent runs without any decrease in activity even after 5 runs. High regio-selectivity toward terminal ring-opening, efficient catalyst reusability using simple magnetic separation, high yields, simplicity in operation and diversity for various substrates are of advantages of this study.http://www.nanochemres.org/article_17358_9b9eebad564279d1015d2dcac6885146.pdfIranian Chemical SocietyNanochemistry Research2538-42791220160701A Facile and Green Biosynthesis of Silver Nanostructures by Aqueous Extract of Suaeda Acuminata after Microwave Assisted Extraction1771821742810.7508/ncr.2016.02.005ENHamid Reza RajabiChemistry Department, Yasouj University, Yasouj, IranHoda DerisChemistry Department, Yasouj University, Yasouj, IranHame Sadat FarajiChemistry Department, Yasouj University, Yasouj, IranJournal Article20160119In the present study, a simple, efficient and fast synthetic strategy was reported for the green biosynthesis of silver nanostructures (<em>i.e.</em> nanoroads and nanoparticles) by the extract of <em>Suaeda Acuminata</em> plant, without any catalyst, template or surfactant. Aqueous extracts were obtained by maceration and microwave assisted extraction (MAE) methods. In MAE procedure, the effect of microwave power on the extracted compounds was studied at 90, 270 and 450 W. Colloidal nano-scaled silver samples were synthesized by reacting aqueous silver nitrate with <em>Suaeda Acuminata</em> leaf extract at non-photomediated conditions. Comparative characterizations of the prepared Ag nanostructures were carried out by different techniques including UV-Vis absorption spectroscopy, scanning electron microscopy, X-ray diffraction, and FT-IR spectroscopy. The SEM images showed that it can be synthesized Ag nanoroads and nanoparticles with the average size of 132 nm and 73 nm, by maceration and MAE methods, respectively. According to UV-Vis absorption spectra, a broad absorption peak around 400 nm was observed for all prepared Ag nanostructure samples synthesized by maceration and MAE methods, at different reaction times and irradiation microwave powers. The band can be corresponded to the plasmon absorbance of nano-scaled silver samples.http://www.nanochemres.org/article_17428_fda84e47a080a15f6a9c2d72ff1848b9.pdfIranian Chemical SocietyNanochemistry Research2538-42791220160701Glucose-based Biofuel Cells: Nanotechnology as a Vital Science in Biofuel Cells Performance1832041744810.7508/ncr.2016.02.006ENHamideh AghahosseiniDepartment of Chemistry, University of Zanjan, Zanjan, IranAli RamazaniDepartment of Chemistry, University of Zanjan, Zanjan, Iran0000-0003-3072-7924Pegah Azimzadeh AsiabiDepartment of Chemistry, University of Zanjan, Zanjan, IranFarideh GouranlouDepartment of Bioscience and Biotechnology, Malek Ashtar University of Technology, Tehran, IranFahimeh HosseiniDepartment of Chemistry, University of Zanjan, Zanjan, IranAram RezaeiDepartment of Chemistry, University of Zanjan, Zanjan, IranBong-Ki MinCenter for Research Facilities, Yeungnam University, Gyeongsan, Republic of KoreaSang Woo JooSchool of Mechanical Engineering, Yeungnam University, Gyeongsan, Republic of KoreaJournal Article20151211Nanotechnology has opened up new opportunities for the design of nanoscale electronic devices suitable for developing high-performance biofuel cells. Glucose-based biofuel cells as green energy sources can be a powerful tool in the service of small-scale power source technology as it provides a latent potential to supply power for various implantable medical electronic devices. By using physiologically produced glucose as a fuel, the living battery can recharge for continuous production of electricity. This review article presents how nanoscience, engineering and medicine are combined to assist in the development of renewable glucose-based biofuel cell systems. Here, we review recent advances and applications in both abiotic and enzymatic glucose biofuel cells with emphasis on their “implantable” and “implanted” types. Also the challenges facing the design and application of glucose-based biofuel cells to convert them to promising replacement candidates for non-rechargeable lithium-ion batteries are discussed. Nanotechnology could make glucose-based biofuel cells cheaper, lighter and more efficient and hence it can be a part of the solutions to these challenges.http://www.nanochemres.org/article_17448_807eca966d900e289b05840a7b8d4bca.pdfIranian Chemical SocietyNanochemistry Research2538-42791220160701A Systematic Study on the Effect of Desilication of Clinoptilolite Zeolite on its Deep-Desulfurization Characteristics2052131761110.7508/ncr.2016.02.007ENRahman MahmoudiChemical Engineering Department, Mahshahr Campus, Amirkabir University of Technology, Mahshahr, IranCavus FalamakiChemical Engineering Department, Mahshahr Campus, Amirkabir University of Technology, Mahshahr, IranChemical Engineering Department, Amirkabir University of Technology, Tehran, IranPetrochemical Center of Excellence, Amirkabir University of Technology, Tehran, IranJournal Article20160106Natural clinoptilolite zeolite (CLP) in its original or metal ion- exchanged form (Ni2+) is a weak adsorbent for relatively large thiophene derivative molecules like benzothiophene (BT) and di-benzothiophene (DBT), due to its rather restricted micro-channel structure. A novelty of this work is that upon desilication treatments, it is possible to enhance the adsorption behavior of Ni2+-exchanged CLP for such large sulfur- containing molecules. A natural CLP zeolite has been desilicated using NaOH solutions in a concentration range of 0.2-2.0 M. The resulting powders have been subjected to XRF, XRD, FTIR, nitrogen adsorption/desorption, TEM and TGA analyses. The adsorption isotherms for the removal of thiophene (TP), BT, DBT and iso-propyl mercaptan (IPM) have been obtained experimentally at 20 °C from simulated liquid fuels using iso-octane as solvent. The sample treated with 1.5 M NaOH solution showed the most significant enhancement in adsorptive properties. The selectivity order is IPM > TP > BT > DBT. Regenerability tests show a quasi constant adsorption capacity after the first cycle. The observed phenomena have been thoroughly discussed based on the physico-chemical analyses of the samples.http://www.nanochemres.org/article_17611_272eca5821e5cc7ecc3561efbe261020.pdfIranian Chemical SocietyNanochemistry Research2538-42791220160701Graphene Oxide-terpyridine Conjugate: A Highly Selective Colorimetric and Sensitive Fluorescence Nano-chemosensor for Fe2+ in Aqueous Media2142211754210.7508/ncr.2016.02.008ENBagher Eftekhari-SisDepartment of Chemistry, University of Maragheh, Maragheh, IranSomayeh MirdoraghiDepartment of Chemistry, University of Maragheh, Maragheh, IranJournal Article20160130A graphene oxide-terpyridine conjugate (GOTC) based colorimetric and fluorescent nano-chemosensor was synthesized.

The structure and properties of microemulsion were characterized by Transmission Electron Microscopy (TEM), Fourier Transform Infrared Spectroscopy (FT-IR), Photo Correlation Spectroscopy (PCS). The effect of the variation in pH value, amount of catalyst, emulsifier and monomer dropping rate on the properties of microemulsion were investigated and discussed. The results showed that the particle size of the latex becomes smaller, and the distribution size becomes wider with increasing the content of catalyst and emulsifier. When pH value changed, the reaction rate of ring-opening of D4 was faster with strong acid than that under the weak acid condition. The emulsification of 2 % OP-10 (Alkylphenol polyoxyethylene ether) and 3.0% DBSA (Dodecyl benzenesulfonic acid) reached to equilibrium in microemulsion. As the amount of OP-10 increases, the size of particles lowered and their corresponding distribution widened. It is observed that emulsifier (OP-10) does not affect the transparency of the microemulsion in the case of the application of DBSA. As the monomer dropping time increased, the grain size diminished and the size distribution widened. PCS results showed that the smallest particle size was around 20nm. Taking into account of the stability of the microemulsions, the dropping time of the monomer was around 30 min.http://www.nanochemres.org/article_39361_9b42daffecde929742ad6ebbd30bc15a.pdfIranian Chemical SocietyNanochemistry Research2538-42791220160701Palladium nanoparticles immobilized on multifunctional hyperbranched polyglycerol-grafted magnetic nanoparticles as a sustainable and efficient catalyst for C-C coupling reactions2372483939410.7508/ncr.2016.02.011ENMina AminiDepartment of Chemistry, Catalysis Division, University of Isfahan, Isfahan, IranMarzieh HajjariDepartment of Chemistry, Catalysis Division, University of Isfahan, Isfahan, IranAmir Landarani-IsfahaniDepartment of Chemistry, Catalysis Division, University of Isfahan, Isfahan, IranValiollah MirkhaniDepartment of Chemistry, Catalysis Division, University of Isfahan, Isfahan, IranMajid MoghadamDepartment of Chemistry, Catalysis Division, University of Isfahan, Isfahan, IranSharam TangestaninejadDepartment of Chemistry, Catalysis Division, University of Isfahan, Isfahan, IranIraj Mohammadpoor-BaltorkDepartment of Chemistry, Catalysis Division, University of Isfahan, Isfahan, IranMohammad AhmadiDepartment of Chemistry, Catalysis Division, University of Isfahan, Isfahan, IranJournal Article20150822This study offers an exclusive class of magnetic nanoparticles supported hyperbranched polyglycerol (MNP/HPG) that was functionalized with citric acid (MNP/HPG-CA) as a host immobilization of palladium nanoparticles.
