  • Application of nanoelements in plant nutrition and its impact in
           ecosystems

    • Authors: América Berenice Morales-Díaz; Hortensia Ortega-Ortíz, Antonio Juárez-Maldonado, Gregorio Cadenas-Pliego, Susana González-Morales Adalberto Benavides-Mendoza

      Abstract: Agriculture stands to benefit from nanotechnology in areas such as combating pests and pathogens, regulating the growth and quality of crops, and developing intelligent materials and nanosensors. The objective of this paper is to provide an overview of the use of nanomaterials (NMs) and nanoparticles (NPs) in plant nutrition, highlighting their advantages and potential uses, but also reviewing their possible environmental destination and effects on ecosystems and consumers. NPs and NMs have been shown to be an attractive alternative for the manufacture of nanofertilizers (NFs), which are more effective and efficient than traditional fertilizers. Because of their impact on crop nutritional quality and stress tolerance in plants, the application of NFs is increasing. However, there are virtually no studies on the potential environmental impact of NPs and NMs when used in agriculture. These studies are necessary because NPs and NMs can be transferred to ecosystems by various pathwa...

  • Biocompatible nanomaterials based on dendrimers, hydrogels and hydrogel
           nanocomposites for use in biomedicine

    • Authors: Cuu Khoa Nguyen; Ngoc Quyen Tran, Thi Phuong Nguyen Dai Hai Nguyen
      First page: 015001
      Abstract: Over the past decades, biopolymer-based nanomaterials have been developed to overcome the limitations of other macro- and micro- synthetic materials as well as the ever increasing demand for the new materials in nanotechnology, biotechnology, biomedicine and others. Owning to their high stability, biodegradability, low toxicity, and biocompatibility, biopolymer-based nanomaterials hold great promise for various biomedical applications. The pursuit of this review is to briefly describe our recent studies regarding biocompatible biopolymer-based nanomaterials, particularly in the form of dendrimers, hydrogels, and hydrogel composites along with the synthetic and modification approaches for the utilization in drug delivery, tissue engineering, and biomedical implants. Moreover, in vitro and in vivo studies for the toxicity evaluation are also discussed.

  • Characterization of the paclitaxel loaded chitosan graft Pluronic F127
           copolymer micelles conjugate with a DNA aptamer targeting HER-2
           overexpressing breast cancer cells

    • Authors: Kim Thach Nguyen; Thu Ha Nguyen, Dinh Ho Do Quang Huan Le
      First page: 015002
      Abstract: In this work we report the isolation of DNA aptamer that is specifically bound to a HER-2 overexpressing SK-BR-3 human breast cancer cell line, using SELEX strategy. Paclitaxel (PTX) loaded chitosan graft Pluronic F127 copolymer micelles conjugate with a DNA aptamer was synthesized and its structure was confirmed by TEM image. This binary mixed system consisting of DNA aptamer modified Pluronic F127 and chitosan could enhance PTX loading capacity and increase micelle stability. Morphology images confirmed the existence of PTX micelles, with an average size of approximately 86.22 ± 1.45 nm diameters. Drug release profile showed that the PTX conjugate maintained a sustained PTX release. From in vitro cell experiment it was shown that 89%–93%, 50%–58%, 55%–62%, 24%–28% and 2%–7% of the SK-BR-3, NS-VN-67, LH-VN-48, HT-VN-26 and NV-VN-31, respectively, were dead after 6–48 h. These results demonstrated a novel DNA aptamer-micelle assembly for efficient detection and a system f...

  • Fabrication of 25 μ m-filter microfluidic chip on silicon substrate

    • Authors: Nguyen Ngan Le; Kim Khanh Huynh, Thi Cam Hue Phan, Thi My Dung Dang Mau Chien Dang
      First page: 015003
      Abstract: This paper presents the entire fabrication process including photolithography, sputtering, deep reactive ion etching (Bosch DRIE process) on silicon substrate and bonding process between the lid and silicon substrate to create a designed filtration microfluidic chip with dimension of 28 mm × 7 mm, one inlet port and one outlet port. A pattered silver thin film was deposited on a silicon sample by the lift-off method. Subsequently the newly fabricated sample was anisotropically etched by Bosch DRIE process. Some parameters of Bosch DRIE process such as bias power, duration of etching step and passivation step, oxygen presence were studied to explore the dependence of silicon channel depth and etched shape profile on these parameters. An optimized process was utilized to fabricate a featured silicon channel with vertical, smooth sidewalls and an overall good uniformity. The silicon channel has four arrays of microposts with various distances between microposts from 25 μ m to...

  • Influence of surface topography on RBS measurements: case studies of
           

    • Authors: M Krupinski; M Perzanowski, Y Zabila, A Zarzycki M Marszałek
      First page: 015004
      Abstract: In this paper the influence of surface topography on Rutherford backscattering spectrometry (RBS) is discussed. (Cu/Fe/Pd) multilayers with total thickness of about 10 nm were deposited by physical vapor deposition on self-organized array of SiO 2 nanoparticles with the size of 50 nm and 100 nm. As a reference, the multilayered systems were also prepared on flat substrates under the same conditions. After the deposition, morphology of the systems was studied by scanning electron microscopy (SEM), while chemical analysis was performed using Rutherford backscattering spectrometry. It was found that the RBS spectra and determined compositions for flat and patterned multilayers differ. The difference is discussed by taking into account the effect of additional inelastic scattering and energy straggling occurring due to developed topography of patterned systems. Then, the multilayers were annealed in 600 °C in order to obtain FePdCu alloy. The phenomenon of solid-state dewe...

  • Hydrogen absorption in uranium-based alloys with cubic γ -U
           structure

    • Authors: L Havela; N-T H Kim-Ngan
      First page: 015005
      Abstract: UH 3 -type hydrides were formed by hydrogenation of splat-cooled U-based alloys upon applying high H 2 pressures (>2.5 bar). Hydrogenation of U 1− x Mo x alloys (with x   ⩾  0.12 (12 at.% Mo) containing the cubic γ -U phase leads to a formation of nanocrystalline β -UH 3 , why those of U 1− x Zr x alloys (with x   ⩾15 at.% Zr) implies a pure α -UH 3 . The Curie temperature of hydride (UH 3 ) 0.85 Mo 0.15 reaches 200 K; it may be the first U-based ferromagnet with such high T C . The results reflect the dominant U–H interaction.

  • High-resolution x-ray diffraction of epitaxial bismuth chalcogenide
           topological insulator layers

    • Authors: V Holý; D Kriegner, H Steiner, J Stangl, G Bauer G Springholz
      First page: 015006
      Abstract: Stoichiometry and lattice structure of epitaxial layers of topological insulators Bi 2 Te 3 and Bi 2 Se 3 grown by molecular-beam epitaxy is studied by high-resolution x-ray diffraction. We show that the stoichiometry of Bi 2 X 3 – δ (X  =  Te, Se) epitaxial layers depends on the additional flux of the chalcogens Te or Se during growth. If no excess flux is employed, the resulting structure is very close to Bi 1 X 1 ( δ   =  1), whereas with a high excess flux the stoichiometric Bi 2 X 3 phase is obtained. From the x-ray data we determined the lattice parameters of the layers and their dependence on composition δ , as well as the degree of crystal quality of the layers.

  • Electronic structure ‘engineering’ in the development of materials for
           Li-ion and Na-ion batteries

    • Authors: Janina Molenda
      First page: 015007
      Abstract: Transition metal oxides with a general formula A x M a O b (A  =  Li, Na, M  =  transition metal) constitute a group of potential electrode materials for a new generation of alkaline batteries. This application is related to the fact that these compounds can reversibly intercalate high amounts of alkaline ions (1 or more moles per mole of M a O b ) already at room temperature, without significant changes in their crystallographic structure. The author of this work basing on her own investigations of A x M a O b (A  =  Li, Na; M  =  3 d , 4 d , 5 d ) has demonstrated that the electronic structure of these materials plays an important role in the intercalation process. Electronic model of intercalation process is presented. Author’s studies show that electronic structure ‘engineering’ is an excellent method of controlling ...

  • Enhanced anticancer efficacy and tumor targeting through folate-PEG
           modified nanoliposome loaded with 5-fluorouracil

    • Authors: Van Minh Le; Trung Duc Tran Nho, Hai Trieu Ly, Thanh Sang Vo, Hoang Dung Nguyen, Thi Thu Huong Phung, Aihua Zou Jianwen Liu
      First page: 015008
      Abstract: Cancer targeted therapies have attracted considerable attention over the past year. Recently, 5-fluouracil (5-FU), which has high toxicity to normal cells and short half-life associated with rapid metabolism, is one of the most commonly used therapies in the treatment of cancer. In this study the folic acid-conjugated pegylated nanoliposomes were synthesized and then loaded into them with 5-FU to improve the anti-tumor efficacy. The average size of liposomes (LPs) was about 52.7 nm which was identified by TEM. In the liposome uptake studies, the level uptake of folate-conjugated liposomes has increased compared to non-conjugated LPs according to LPs concentration, incubation time and presence of concentration of free folic acid (FA). The MTT assay and apoptotic test were carried out in HCT116 and MCF-7 cells for 24 or 48 h. The results revealed that the folate-PEG modified 5-Fu loaded nanoliposomes had strong cytotoxicity to cancer cell compared to pure 5-FU or PEG modified 5-FU...

  • Fabrication of a TiO 2 @porphyrin nanofiber hybrid material: a highly
           efficient photocatalyst under simulated sunlight irradiation

    • Authors: Duong Duc La; Anushri Rananaware, Hoai Phuong Nguyen Thi, Lathe Jones Sheshanath V Bhosale
      First page: 015009
      Abstract: The solar spectrum consists of 8% UV radiation, while 45% of solar energy is from visible light. It is therefore desirable to fabricate a hybrid material which is able to harvest energy from a wide range of photons from the sun for applications such as solar cells, photovoltaics, and photocatalysis. In this study we report on the fabrication of a TiO 2 @porphyrin hybrid material by surfactant-assisted co-assembly of monomeric porphyrin molecules with TiO 2 nanoparticles. The obtained TiO 2 @porphyrin composite shows excellent integration of TiO 2 particles with diameters of 15–30 nm into aggregated porphyrin nanofibers, which have a width of 70–90 nm and are several µm long. SEM, XPS, XRD, FTIR, UV–Vis and fluorescence spectroscopy were employed to characterize the TiO 2 @TCPP hybrid material. This material exhibits efficient photocatalytic performance under simulated sunlight, due to synergistic photocatalytic activities of the por...

  • Structure, characterization, and magnetic/electrochemical properties of
           Ni-doped BiFeO 3 nanoparticles

    • Authors: Jessada Khajonrit; Natkrita Prasoetsopha, Tanayt Sinprachim, Pinit Kidkhunthod, Supree Pinitsoontorn Santi Maensiri
      First page: 015010
      Abstract: The BiFe 1− x Ni x O 3 ( x   =  0, 0.05, 0.1, 0.2, and 0.3) nanoparticles were prepared by a simple solution method. Their nanostructures were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), x-ray absorption spectroscopy (XAS) and gas absorption techniques. The magnetic properties of the nanoparticles were studied by using a vibrating sample magnetometer (VSM). The increasing of Ni content with decreasing of crystallize size can improve magnetization. Moreover, the samples were fabricated as electrodes to study the electrochemical properties by cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) and electrochemical impedance spectroscopy (EIS). The high specific capacitances of the electrodes are in the range of 193–514 F g −1 . Although the increasing of the Ni content leads to decreasing of the specific capacitances, the 5% Ni-doped BiFeO
