Graphical abstract
Highlights► Models of increase in dispersion and solubility of chitosan-wrapped SWCNTs. ► MD simulations with three different chitosan concentrations were performed. ► Pristine CNT aggregates due to tube-tube hydrophobic and vdW interactions. ► At low concentration, chitosan on one tube bridges another to aggregate. ► Charge-charge repulsion leads to well dispersion of wrapped CNTs in solution. | | | 4. | How does organic matter constrain the nature, size and availability of Fe nanoparticles for biological reduction? Original Research Article Journal of Colloid and Interface Science, In Press, Accepted Manuscript, Available online 24 March 2011 Mathieu Pédrot, Ange Le Boudec, Mélanie Davranche, Aline Dia, Odile Henin
Graphical abstractTransmission Electron Microscopy micrographs of Fe nanoparticles: (a) and (b) correspond to pure Fe system; whereas (c) and (d) correspond to Fe-HA system. Highlights► New data demonstrating the impact of HS on the formation and reactivity of iron oxides ► Humic substances slow down and reduce the extent of the Fe oxidation-hydrolysis reaction ► Humic substance directly impact the size and the nature of formed Fe oxides ► A fraction of Fe does not contribute to the genesis of nanoparticles, forming instead stable HS-Fe2+ and HS-Fe3+ complexes - Mixed Fe nanoparticles-organic colloids are much more bioavailable and more labile than Fe oxides formed in organic-depleted environment. | | | 5. | Fast functionalization of multi-walled carbon nanotubes by an atmospheric pressure plasma jet Original Research Article Journal of Colloid and Interface Science, In Press, Accepted Manuscript, Available online 24 March 2011 Daniel Kolacyak, Jörg Ihde, Christian Merten, Andreas Hartwig, Uwe Lommatzsch
Graphical abstractFunctionalization of multi-walled carbon nanotubes with a novel atmospheric pressure plasma process incorporates about 6.6 at-% of oxygen and is proposed as an alternative to acidic treatment. Highlights►Atmospheric pressure plasma enhances dispersibility of multi-walled carbon nanotubes ► Plasma treatment introduces hydroxylic and carboxylic functional groups ► Functionalization occurs within less than 1 s of effective plasma treatment ► CNT morphology is largely preserved in plasma treatment | | | 6. | Spherical shape with fast decaying property of solvothermally grown (Y,Gd)BO3:Eu3+ nanophosphor Original Research Article Journal of Luminescence, In Press, Accepted Manuscript, Available online 24 March 2011 Sungho Choi, Byung-Yoon Park, Ha-Kyun Jung
Highlights► Solvothermally grown spherical with fast-decaying (Y,Gd)BO3:Eu3+ phosphor. ► Understanding the emission decay related to surface-induced radiative transitions. ► Applicable to the promising red-emitting phosphor for ongoing 3D PDP devices. | | | 13. | Surface characteristics, nano-indentation and corrosion behavior of Nb implanted NiTi alloy Original Research Article Surface and Coatings Technology, In Press, Accepted Manuscript, Available online 24 March 2011 Tingting Zhao, Yan Li, Yan Xiang, Xinqing Zhao, Tao Zhang
Research highlights►Nb implantation is able to form Nb2O5/TiO2 nano-film on NiTi alloy. ►Nb implantation decreases the Nano-hardness and Young's modulus of NiTi. ►Corrosion resistance behavior of NiTi is improved by Nb2O5/TiO2 nano-film. ►A moderate incident dose or current causes better corrosion resistance ability. | | | 14. | Nano composite Si2Sb2Te film for phase change memory Original Research Article Thin Solid Films, In Press, Accepted Manuscript, Available online 24 March 2011 Feng Rao, Kun Ren, Yifeng Gu, Zhitang Song, Liangcai Wu, Xilin Zhou, Bo Liu, Songlin Feng, Bomy Chen | | | 20. | Desorption induced formation of negative nanowires in GaN Original Research Article Journal of Crystal Growth, In Press, Accepted Manuscript, Available online 23 March 2011 Bong-Joong Kim, Eric A. Stach
Highlights► Negative nanowires are grown via solid-vapor and solid-liquid-vapor mechanisms in the GaN system. ► Vertical negative nanowires show hexagonal shape while lateral negative nanowires are kinked. ► Rate limiting step of lateral negative nanowires is thermally activated − Ga catalyzed dissociation of GaN. | | | 22. | Tuning the growth of ZnO nanowires Original Research Article Physica B: Condensed Matter, In Press, Accepted Manuscript, Available online 23 March 2011 Z.
