Research highlights►CHx and CHxO species adsorbed on various sites of a Pd79 nanoparticle are studied. ► For that, density-functional calculations are performed. ► The structures, energies and vibrations of the adsorption complexes are considered. ► Low coordinated sites can bind by up to 20-50 kJ/mol stronger than the terrace sites. ► Spectroscopic detection of the adsorbates on terrace and edge Pd sites is addressed. | | | 11. | Interactions of hydrophilic silica nanoparticles and classical surfactants at non-polar oil-water interface Original Research Article Journal of Colloid and Interface Science, In Press, Accepted Manuscript, Available online 2 March 2011 Nasrin Ghouchi Eskandar, Spomenka Simovic, Clive A. Prestidge
Graphical abstractFreeze fracture-SEM of silica-coated oleylamine-stabilised liquid paraffin-in-water emulsions (inset image) showed scattered particle flocs at the droplet surface in line with low magnitude of the attachment energy (E<500 kT) and poor physical stability. Research highlights► This work aims to investigate synergistic stabilisation of paraffin oil-in-water emulsions using conventional surfactants and hydrophilic fasilica nanoparticles. ► The attachment energy silica nanoparticles at the paraffin oil (dissolved lecithin)-water interface was calculated to be 900-4500 kT. ► The attachment energy silica nanoparticles at the paraffin oil (dissolved oleylamine)-water interface was calculated to be 250-550 kT ► Calculated attachment energies correlated well with the long-term emulsion stability, which is significantly higher for lecithin/silica stabilised emulsions. | | | 12. | Sol-gel synthesis of iron(III) oxyhydroxide nanostructured monoliths using Fe(NO3)3·9H2O/CH3CH2OH/NH4OH ternary system Original Research Article Journal of Physics and Chemistry of Solids, In Press, Accepted Manuscript, Available online 2 March 2011 Luísa Durães, Orlando Oliveira, Leandro Benedini, Benilde F.O. Costa, Ana Matos Beja, António Portugal
Research highlights► γ-FeO(OH) xerogels were produced using iron(III) nitrate nonahydrate precursor. ► Monolithic gels were never obtained with this precursor and NH4OH gelation agent. ► Large clusters of well connected nanocrystallites of iron oxyhydroxide. ► NH4NO3 by-product is retained inside the iron oxyhydroxide structure. ► Promising oxidizing composite for the energetic materials area. | | | 13. | Study of nanodispersed aluminum and iron alcosols by photoacoustic spectroscopy Original Research Article Optics Communications, In Press, Uncorrected Proof, Available online 2 March 2011 Vladimir An, Charles de Izarra, Gennady Saveliev
Research Highlights► The photoacoustic signal (PAS) obtained by modulated CO2 laser irradiation (1.026 and 1.096 kHz) of alcosols depends on the nature and method of nanoparticles fabrication. ► The effect does not depend on the sol concentration in the range of 1–5 g/l. ► An explosive chemical reaction initiated by laser irradiation can be a source of a photoacoustic signal. | | | 16. | Nanostructured porous ZnO film with enhanced photocatalytic activity Original Research Article Thin Solid Films, In Press, Accepted Manuscript, Available online 2 March 2011 Lina Wang, Yingying Zheng, Xiaoyun Li, Wenjun Dong, Weihua Tang, Benyong Chen, Chaorong Li, Xiao Li, Tierui Zhang, Wei Xu | | | 17. | Micropatterned nanocrystalline zinc oxide thin films obtained through metal-loaded hydrogels Original Research Article Thin Solid Films, In Press, Accepted Manuscript, Available online 2 March 2011 I.G.

Graphical abstractA novel amphiphilic three-armed peptide, in which three β-sheet formable peptides (L4K8L4) were connected by Lys residue, showed the pH-dependent self-assembly into shape-specific nanofibers with morphologically kinked structures. Research highlights► A novel amphiphilic branched peptide containing three ®-sheet formable peptides was newly prepared as a building block for self-assembly. ► Conformation of the branched peptide could be easily controlled by manipulating the solution pH. ► The branched peptide was found to form a shape-specific ®-sheet-based nanofiber with morphologically kinked structure via self-assembly. | | | 23. | Carbon Nanoparticle Ionic Liquid Hybrids and Their Photoluminescence Properites Original Research Article Journal of Colloid and Interface Science, In Press, Accepted Manuscript, Available online 1 March 2011 Ying Wei, Yang Liu, Haitao Li, Xiaodie He, Qingguo Zhang, Zhenhui Kang, Shuit-Tong Lee
