We report the use of bis-catecholic polymers as candidates for obtaining effective, tunable gatekeeping coatings for mesoporous silica nanoparticles (MSNs) intended for drug release applications. In monomers, catechol rings act as adhesive moieties and reactive sites for polymerization, together with middle linkers which may be chosen to tune the physicochemical properties of the resulting coating.

25 p, 779.1 KB Colloidal Silicon-Germanium Nanorod Heterostructures / Lu, Xiaotang (University of Texas. Texas Materials Institute) ; De La Mata, Maria (Institut Català de Nanociència i Nanotecnologia) ; Arbiol i Cobos, Jordi (Institut Català de Nanociència i Nanotecnologia) ; Korgel, Brian A. (University of Texas. Texas Materials Institute)
Colloidal nanorods with axial Si and Ge heterojunction segments were produced by solution-liquid-solid (SLS) growth using Sn as a seed metal and trisilane and diphenylgermane as Si and Ge reactants. The low solubility of Si and Ge in Sn helps to generate abrupt Si-Ge heterojunction interfaces. [...]

28 p, 1.9 MB Reduction of Thermal Conductivity in Nanowires by Combined Engineering of Crystal Phase and Isotope Disorder / Mukherjee, Samik (Polytechnique Montréal. Département de génie physique) ; Givan, Uri (Max Planck Institute of Microstructure Physics) ; Senz, Stephan (Max Planck Institute of Microstructure Physics) ; De La Mata, Maria (Institut Català de Nanociència i Nanotecnologia) ; Arbiol i Cobos, Jordi (Institut Català de Nanociència i Nanotecnologia) ; Moutanabbir, Oussama (École Polytechnique de Montréal. Department of Engineering Physics)
Nanowires are a versatile platform to investigate and harness phonon and thermal transport phenomena in nanoscale systems. With this perspective, we demonstrate herein the use of crystal phase and mass disorder as effective degrees of freedom to manipulate the behavior of phonons and control the flow of local heat in silicon nanowires.

11 p, 773.1 KB Fabrication of well-ordered silicon nanopillars embedded in a microchannel : Via metal-assisted chemical etching: A route towards an opto-mechanical biosensor / Solís Tinoco, Verónica Iraís (Institut Català de Nanociència i Nanotecnologia) ; Márquez, Salomón (Institut Català de Nanociència i Nanotecnologia) ; Sepúlveda, Borja (Institut Català de Nanociència i Nanotecnologia) ; Lechuga, Laura M (Institut Català de Nanociència i Nanotecnologia)
Ordered nanopillars have been used as a smart configuration to design and fabricate localized surface plasmon resonance (LSPR) sensors. Importantly, these nanostructures can be integrated within microfluidic channels as a novel opportunity to enhance the response of biosensors and also to control the fluid flow by modifying the wettability surface of the walls.

9 p, 1.3 MB Thermal conductivity in disordered porous nanomembranes / Sledzinska, Marianna (Institut Català de Nanociència i Nanotecnologia) ; Graczykowski, Bartlomiej (Max Planck Institute for Polymer Research) ; Alzina, Francesc (Institut Català de Nanociència i Nanotecnologia) ; Melia, Umberto (Universitat Politècnica de Catalunya. Departament d'Enginyeria de Sistemes, Automàtica i Informàtica Industrial) ; Termentzidis, Konstantinos (Centre National de la Recherche Scientifique (França)) ; Lacroix, David (Centre National de la Recherche Scientifique (França)) ; Sotomayor Torres, Clivia M. (Institut Català de Nanociència i Nanotecnologia)
In this work we study the effects of disorder on the thermal conductivity of porous 100 nm thick silicon membranes, in which the size, shape and position of the pores were varied randomly. Measurements using two-laser Raman thermometry on both non-patterned and porous membranes revealed more than a 10-fold reduction of the thermal conductivity compared to that of bulk silicon and a six-fold reduction compared to non-patterned membranes for the sample with random pore shapes.

15 p, 4.0 MB Metamirrors Based on Arrays of Silicon Nanowires with Height Gradients / Otte Ortiz, Marinus Albertus (Institut Català de Nanociència i Nanotecnologia) ; García Martín, Antonio (Instituto de Microelectrónica de Madrid) ; Borrisé, Xavier (Institut Català de Nanociència i Nanotecnologia) ; Sepúlveda, Borja (Institut Català de Nanociència i Nanotecnologia)
Arrays of silicon nanowires with height gradients fabricated using metal-assisted chemical etching act as tunable metamirrors enabling light focusing the reflected light in arbitrary shapes. Metamirrors with non-cylindrical nanowires can simultaneously focus the reflected light and induce strong polarization conversion effect.
