  • Mechanism of acid corrosion inhibition using magnetic nanofluid

    • Authors: Kinnari Parekh; Smita Jauhari R V Upadhyay
      First page: 045007
      Abstract: The inhibition effect of magneticnanofluid on carbon steel in acid solutions was investigated using gravimetric, potentiodynamic and SEM measurement. The inhibition efficiency increases up to 95% and 75% for 51.7 mM concentration, respectively, in 1 M HCl and 1 M H 2 SO 4 medium. The adsorption of nanoparticles to the steel surface forms a barrier between the metal and the aggressive environment, which is responsible for observed inhibition action. The adsorption of nanoparticles on steel surface is supported by the Langmuir and Freundlich adsorption isotherm and surface morphology scanned through SEM.

  • Effect of potassium on structural, photocatalytic and antibacterial
           activities of ZnO nanoparticles

    • Authors: R Bhaviya Raj; M Umadevi, V Poornima Parvathi R Parimaladevi
      First page: 045008
      Abstract: ZnO and potassium doped ZnO nanoparticles were synthesized through wet chemical method. The samples were characterized by UV, XRD, SEM, TEM and EDAX. XRD analysis reveals that the prepared nanoparticles exhibit hexagonal wurtzite structure. TEM and SEM analyses disclose that synthesized samples were porous structure with needle shape. It also confirms that potassium was dispersed on ZnO surface. The influence of potassium on ZnO surface modulates the degradation of textile dyeing wastewater by improving its rate of decomposition to 0.007 min −1 with decoloration. A better zone of inhibition of about 20 mm against Staphylococci aureus and Pseudomonas aernginosa by ZnO and potassium doped ZnO nanoparticles were measured. The findings suggest that these nanoparticles have the potential to be a good photocatalyst and applied in water treatment to inhibit the bacterial growth.

  • Antibacterial and photocatalytic degradation efficacy of silver
           nanoparticles biosynthesized using Cordia dichotoma leaf extract

    • Authors: R Mankamna Kumari; Nikita Thapa, Nidhi Gupta, Ajeet Kumar Surendra Nimesh
      First page: 045009
      Abstract: The present study focuses on the biosynthesis of silver nanoparticles (AgNPs) along with its antibacterial and photocatalytic activity. The AgNPs were synthesized using Cordia dichotoma leaf extract and were characterized using UV-vis spectroscopy to determine the formation of AgNPs. FTIR was done to discern biomolecules responsible for reduction and capping of the synthesized nanoparticles. Further, DLS technique was performed to examine its hydrodynamic diameter, followed by SEM, TEM and XRD to determine its size, morphology and crystalline structure. Later, these AgNPs were studied for their potential role in antibacterial activity and photocatalytic degradation of azo dyes such as methylene blue and Congo red.

  • Synthesis and characterization of chitosan-coated magnetite nanoparticles
           and their application in curcumin drug delivery

    • Authors: Xuan Nui Pham; Tan Phuoc Nguyen, Tuyet Nhung Pham, Thi Thuy Nga Tran Thi Van Thi Tran
      First page: 045010
      Abstract: In this work anti-cancer drug curcumin-loaded superparamagnetic iron oxide (Fe 3 O 4 ) nanoparticles was modified by chitosan (CS). The magnetic iron oxide nanoparticles were synthesized by using reverse micro-emulsion (water-in-oil) method. The magnetic nanoparticles without loaded drug and drug-loaded magnetic nanoparticles were characterized by XRD, FTIR, TG-DTA, SEM, TEM, and VSM techniques. These nanoparticles have almost spherical shape and their diameter varies from 8 nm to 17 nm. Measurement of VSM at room temperature showed that iron oxide nanoparticles have superparamagnetic properties. In vitro drug loading and release behavior of curcumin drug-loaded CS-Fe 3 O 4 nanoparticles were studied by using UV-spectrophotometer. In addition, the cytotoxicity of the modified nanoparticles has shown anticancer activity against A549 cell with IC 50 value of 73.03 μ g/ml. Therefore, the modified magnetic nanoparticles can...

  • Preparation of Ag/SiO 2 nanocomposite and assessment of its antifungal
           effect on soybean plant (a Vietnamese species DT-26)

    • Authors: Hoai Chau Nguyen; Thi Thuy Nguyen, Trong Hien Dao, Quoc Buu Ngo, Hoang Long Pham Thi Bich Ngoc Nguyen
      First page: 045014
      Abstract: Soybean crop losses due to fungal diseases are considerable and directly depend on the severity of the disease. The objective of this study was to assess antifungal activity of silver/silica (Ag/SiO 2 ) nanocomposite against crop pathogenic fungi ( Fusarium oxysporium and Rhizoctonia solani ) in soybean farming. Firstly, silica particles with a size ranging from 20 to 30 nm were modified with 3-aminopropyl triethoxysilane (APTES) for 2 h. Then these amino acid - functionalized silica particles were exposed to silver ion solution followed by reduction of silver ions with sodium borohydride to form Ag/SiO 2 nanocomposite. The formation of the linkage between APTES and silica particles was confirmed by Fourier transform infrared (FTIR) spectroscopy. The surface plasmon absorption maximum at 400 nm confirmed the nano essence of the silver particles on silica particles. For the seed coating, bentonite from Lam Dong deposit, Vietnam, was used as an encap...

  • Effect of rutile titania dioxide nanoparticles on the mechanical property,
           thermal stability, weathering resistance and antibacterial property of
           styrene acrylic polyurethane coating

    • Authors: Thien Vuong Nguyen; Tuan Anh Nguyen, Phi Hung Dao, Van Phuc Mac, Anh Hiep Nguyen, Minh Thanh Do The Huu Nguyen
      First page: 045015
      Abstract: This study aims to enhance the mechanical properties, thermal stability, weathering resistance and antibacterial property of a styrene acrylic polyurethane coating by adding rutile titania dioxide (R-TiO 2 ) nanoparticles in coating formulation. The styrene acrylic polyurethane/R-TiO 2 nanocomposite had been prepared by using ultrasonication. The effects of nanoparticles on the mechanical properties, thermal stability and weathering resistance of as-prepared coatings were investigated by using the adhesion strength and ball impact tests, the Fourier transform infrared and UV–vis analyses, thermogravimetric analysis (TGA), and UV/condensation weathering chamber equipped with UVA-340 fluorescent lamps, respectively. The disperse quality of nanoparticles in the coating was examined by using the field emission scanning electron microscope (FESEM). The mechanical test results showed that suitable content of R-TiO 2 nanoparticles in the nanocomposite coati...

  • Highly efficient growth of vertically aligned carbon nanotubes on Fe–Ni
           based metal alloy foils for supercapacitors

    • Authors: Raja Noor Amalina Raja Seman; Mohd Asyadi Azam Mohd Ambri Mohamed
      First page: 045016
      Abstract: Supercapacitors are highly promising energy devices with superior charge storage performance and a long lifecycle. Construction of the supercapacitor cell, especially electrode fabrication, is critical to ensure good performance in applications. This work demonstrates direct growth of vertically aligned carbon nanotubes (CNTs) on Fe–Ni based metal alloy foils, namely SUS 310S, Inconel 600 and YEF 50, and their use in symmetric vertically aligned CNT supercapacitor electrodes. Alumina and cobalt thin film catalysts were deposited onto the foils, and then CNT growth was performed using alcohol catalytic chemical vapour deposition. By this method, vertically aligned CNTs were successfully grown and used directly as a binder-free supercapacitor electrode to deliver excellent electrochemical performance. The device showed relatively good specific capacitance, a superior rate capability and excellent cycle stability, maintaining about 96% capacitance up to 1000 cycles.

  • Square-inch 2D-arrays of Au nanodisks fabricated by sputtering Au onto
           anodic aluminum oxide templates for SERS applications

    • Authors: Thi Thuy Nguyen; Thi Dieu Thuy Ung Quang Liem Nguyen
      First page: 045017
      Abstract: Two-dimensional (2D) arrays of gold nanodisks (Au NDs) with different sizes of 75, 95 and 115 nm, with the distances between NDs of 10, 30 and 50 nm were fabricated on square-inch substrates. The optimal conditions regarding the thickness of anodic aluminum oxide (AAO) template, sputtering time and annealing temperature for Au, lift-off the walls of AAO template for getting the highest quality 2D arrays of Au NDs have been determined. Morphology and surface plasmon resonance (SPR) absorption of the 2D arrays of Au NDs were examined by using appropriate techniques. The 2D arrays of fabricated Au NDs show different SPRs peaking in the spectral range of 600–1600 nm, which are very promising for surface-enhanced Raman scattering (SERS)-based sensor applications. As an example for the potential use of fabricated SERS substrates, we have demonstrated the detection of methamidophos at various concentrations ranging from 1 ppb to 10 3 ppm. Moreover, the method we have used to ...

  • Biofabricated zinc oxide nanoparticles coated with phycomolecules as novel
           micronutrient catalysts for stimulating plant growth of cotton

    • Authors: N Priyanka; P Venkatachalam
      First page: 045018
      Abstract: This study describes the bioengineering of phycomolecule-coated zinc oxide nanoparticles (ZnO NPs) as a novel type of plant-growth-enhancing micronutrient catalyst aimed at increasing crop productivity. The impact of natural engineered phycomolecule-loaded ZnO NPs on plant growth characteristics and biochemical changes in Gossypium hirsutum L. plants was investigated after 21 days of exposure to a wide range of concentrations (0, 25, 50, 75, 100, and 200 mg l −l ). ZnO NP exposure significantly enhanced growth and biomass by 125.4% and 132.8%, respectively, in the treated plants compared to the untreated control. Interestingly, photosynthetic pigments, namely, chlorophyll a (134.7%), chlorophyll b (132.6%), carotenoids (160.1%), and total soluble protein contents (165.4%) increased significantly, but the level of malondialdehyde (MDA) content (73.8%) decreased in the ZnO-NP-exposed plants compared to the control. The results showed that there were s...

  • The dual effect of curcumin nanoparticles encapsulated by 1-3/1-6 β
           -glucan from medicinal mushrooms Hericium erinaceus and Ganoderma
           lucidum

    • Authors: Mai Huong Le; Hai Doan Do, Hong Ha Tran Thi, Le Vu Dung, Hoai Nam Nguyen, Hang Nhu Tran Thi, Luyen Dinh Nguyen, Chi Kim Hoang, Huu Cuong Le, Thu Huong Le Thi, Hoang Trung Trinh Phuong Thu Ha
      First page: 045019
      Abstract: Curcumin is a polyphenol from turmeric Curcuma longa L that has been proved to possess numerous biological and pharmaceutical activities, including anti-cancer properties. However, curcumin has only limited clinical applications due to the aqueous insolubility characteristic that reduces its biological availability. On the other hand, using nanoparticles as drug delivery system has potential as it increases solubility of hydrophobic substances such as curcumin. Furthermore, nanoparticles can protect and control release of drug. Therefore, the objective of this project is to prepare nanoparticles by polymeric encapsulating curcumin by 1-3/1-6 β -glucan extracted from Vietnamese mushrooms to increase drug delivery efficiency and biological effect. Method of the preparation is nano-precipitation. The produced curcumin- β -glucan-nanoparticles (NanoGluCur) takes spherical shape with 60–70 nm in diameter. As expected, water solubility of curcumin increases about 180...
