Adsorption of linear macromolecules (modeled as infinitesimally thin needles), on a two-dimensional continuum substrate is studied using RSBA model.

Synthesis of gold and silver nanoparticles anchoring on the pores of S-layer is achieved by chemical reduction of respective metal salt laden protein template. Transmission electron microscopy reveals formation of well ordered and separated gold and silver nanoparticles with an average diameter of 6 +/- 1 nm and 4 +/- 1 nm, respectively.

Magnetosome membranes along with some specific membrane proteins regulate crystal nucleation and morphology of magnetite. Several previous works have indicated that the morphology of mature magnetite crystals is largely unaffected by environmental conditions, though some recent studies have shown the possibility of manipulation of the biomineralization process. In this study we have examined the effects of high concentrations of Zinc and Nickel on the growth of Magnetospirillum magnetotacticum (MS-1) and the corresponding magnetosome formation. Using various characterizations it is shown that the growth of the bacterial cells, as well as the size, shape and magnetosome chain alignment is significantly influenced in the presence of high concentrations of Zn or Ni.

Arrays of well-aligned ZnO nanorods of uniform diameter have been synthesized on the Si substrate precoated with Au, using a simple electron beam evaporation method without the flow of any carrier gas. Scanning electron microscopy and atomic force microscopy characterizations show that as-grown nanorods are well aligned and uniform in diameter. X-ray diffraction measurements and clear lattice fringes in high-resolution transmission electron microscopy image show the growth of good quality polycrystalline hexagonal ZnO nanorods and a &lt; 0 0 2 &gt; growth direction. The polarization-dependent studies of near edge x-ray absorption fine structure (NEXAFS) are performed to investigate the electronic structure of the zinc and oxygen ions. The analysis of NEXAFS spectra at different angles of incidence of photon flux indicates the formation of ZnO nanorods having anisotropic behaviour of O and Zn states. The photoluminescence spectrum exhibits strong ultraviolet emission at 385 nm and the UV-visible spectrum also shows a band-gap transition around 390 nm indicating the good quality of nanorods. The catalytic growth mechanism of the ZnO nanorods is discussed on the basis of experimental results in this work.</p>1 aAgarwal, Dinesh, C.1 aChauhan, R., S.1 aAvasthi, D., K.1 aSulania, I.1 aKabiraj, D.1 aThakur, P.1 aChae, K., H.1 aChawla, Amit1 aChandra, Ramesh1 aOgale, S., B.1 aPellegrini, G.1 aMazzoldi, P.  uhttps://library.ncl.res.in/content/vls-growth-and-characterizations-dense-zno-nanorods-grown-e-beam-process-002190nas a2200277   4500008004100000022001400041245009100055210006900146260009200215300001200307490000600319520125600325653001601581653001801597653001201615653001301627653001701640100001801657700001801675700001901693700002401712700001801736700002001754700001801774856012001792       2011                        eng d  a1936-661200aControlling stoichiometry in low temperature synthesis of La0.7Sr0.3MnO3 nanoparticles0 aControlling stoichiometry in low temperature synthesis of La07Sr  a26650 THE OLD RD, STE 208, VALENCIA, CA 91381-0751 USAbAMER SCIENTIFIC PUBLISHERScFEB  a424-4300 v43 a<p>Nanoparticles of complex oxides (&lt;20 nm) are desirable for several applications in view of the diverse range of physical properties of such oxides. However the simultaneous presence of multiple cation precursors makes the corresponding chemical synthesis non-trivial with possible intermediate evolution of secondary phases. Such phases could react at high temperatures to form the desired stoichiometry, but this process is diffusion limited and can lead to larger particles. In this work we examine the role of three different reaction and growth controlling additives, namely dextran, citric acid and hexamine, on the synthesis of the well known colossal magneto-resistive (CMR) manganite La0.7Sr0.3MnO3. We demonstrate that phase evolutions differ significantly in the three cases, and the physical properties of the products also differ dramatically. Only dextran is shown to yield the desired phase with faceted nanoparticles at as low a temperature as 600 degrees C. A high saturation moment of similar to 47 emu/gm is realized at 10 K with a good square hysteresis loop. In 650 degrees C annealed sample, room temperature magnetization of similar to 15 emu/gm was obtained, which brings the nanoparticles in the applicability domain.</p>10aCitric acid10aComplex Oxide10aDextran10aHexamine10ahydrothermal1 aAzarifar, Ali1 aYadav, P., A.1 aChawla, A., K.1 aJog, Jyoti, Prakash1 aPatil, S., I.1 aChandra, Ramesh1 aOgale, S., B.  uhttps://library.ncl.res.in/content/controlling-stoichiometry-low-temperature-synthesis-la07sr03mno3-nanoparticles-001985nas a2200217   4500008004100000022001400041245011800055210006900173260012500242300002300367490000600390520111300396100002001509700002001529700001501549700001801564700002301582700002401605700001801629856012001647       2012                        eng d  a2158-322600aFrom small aromatic molecules to functional nanostructured carbon by pulsed laser-induced photochemical stitching0 aFrom small aromatic molecules to functional nanostructured carbo  aCIRCULATION & FULFILLMENT DIV, 2 HUNTINGTON QUADRANGLE, STE 1 N O 1, MELVILLE, NY 11747-4501 USAbAMER INST PHYSICScJUN  aArticle No. 0221300 v23 a<p>A novel route employing UV laser pulses (KrF Excimer, 248 nm) to cleave small aromatic molecules and stitch the generated free radicals into functional nanostructured forms of carbon is introduced. The process differs distinctly from any strategies wherein the aromatic rings are broken in the primary process. It is demonstrated that this pulsed laser-induced photochemical stitching (PLPS) process when applied to routine laboratory solvents (or toxic chemical wastes when discarded) Chlorobenzene and o-Dichlorobenzene yields Carbon Nanospheres (CNSs) comprising of graphene-like sheets assembled in onion-like configurations. This room temperature process implemented under normal laboratory conditions is versatile and clearly applicable to the whole family of haloaromatic compounds without and with additions of precursors or other nanomaterials. We further bring out its applicability for synthesis of metal-oxide based carbon nanocomposites. Copyright 2012 Author(s).
