Towards defect-free 1-D GaAs/AlGaAs heterostructures based on GaAs nanomembranes.

Nanoscale

Tutuncuoglu G, de la Mata M, Deiana D, Potts H, Matteini F, Arbiol J, Fontcuberta i Morral A.
PMID: 26416625
Nanoscale. 2015 Dec 14;7(46):19453-60. doi: 10.1039/c5nr04821d. Epub 2015 Sep 29.

We demonstrate the growth of defect-free zinc-blende GaAs nanomembranes by molecular beam epitaxy. Our growth studies indicate a strong impact of As4 re-emission and shadowing in the growth rate of the structures. The highest aspect ratio structures are obtained...

Crystallographically Textured Nanomaterials Produced from the Liquid Phase Sintering of Bi .

Nano letters

Liu Y, Zhang Y, Ortega S, Ibáñez M, Lim KH, Grau-Carbonell A, Martí-Sánchez S, Ng KM, Arbiol J, Kovalenko MV, Cadavid D, Cabot A.
PMID: 29546994
Nano Lett. 2018 Apr 11;18(4):2557-2563. doi: 10.1021/acs.nanolett.8b00263. Epub 2018 Mar 20.

Bottom-up approaches for producing bulk nanomaterials have traditionally lacked control over the crystallographic alignment of nanograins. This limitation has prevented nanocrystal-based nanomaterials from achieving optimized performances in numerous applications. Here we demonstrate the production of nanostructured Bi

p-GaN/n-ZnO heterojunction nanowires: optoelectronic properties and the role of interface polarity.

ACS nano

Schuster F, Laumer B, Zamani RR, Magén C, Morante JR, Arbiol J, Stutzmann M.

ACS Nano. 2014 May 27;8(5):4376-84. doi: 10.1021/nn406134e. Epub 2014 Apr 23.

In this work, simulations of the electronic band structure of a p-GaN/n-ZnO heterointerface are presented. In contrast to homojunctions, an additional energy barrier due to the type-II band alignment hinders the flow of majority charge carriers in this heterojunction....

Size and aspect ratio control of Pd₂Sn nanorods and their water denitration properties.

Langmuir. 2015 Apr 07;31(13):3952-7. doi: 10.1021/la504906q. Epub 2015 Mar 23.

Monodisperse Pd2Sn nanorods with tuned size and aspect ratio were prepared by co-reduction of metal salts in the presence of trioctylphosphine, amine, and chloride ions. Asymmetric Pd2Sn nanostructures were achieved by the selective desorption of a surfactant mediated by...

Validating the use of intrinsic markers in body feathers to identify inter-individual differences in non-breeding areas of northern fulmars.

Mar Biol. 2016;163:64. doi: 10.1007/s00227-016-2822-1. Epub 2016 Feb 29.

Many wildlife studies use chemical analyses to explore spatio-temporal variation in diet, migratory patterns and contaminant exposure. Intrinsic markers are particularly valuable for studying non-breeding marine predators, when direct methods of investigation are rarely feasible. However, any inferences regarding...

Identifying the physical features of marina infrastructure associated with the presence of non-native species in the UK.

Marine invasive non-native species (NNS) are one of the greatest threats to global marine biodiversity, causing significant economic and social impacts. Marinas are increasingly recognised as key reservoirs for invasive NNS. They provide submersed artificial habitat that unintentionally supports...

Larvae of the tunicate Ciona start metamorphosis between some hours and a few days after hatching. Several substances were found to reduce this time span, such as vital dyes [Cloney (1961) Am Zool 1:67-87; Hirani (1961) Bull Mar Biol...

Fused is a segmentation gene belonging to the segment-polarity class. Mutations at thefused locus are known to display pleiotropic effects, causing zygotically determined anomalies of ovaries and of some adult cuticular structures, and maternally determined embryonic segmentation defects. In...

Growth rates of newly-metamorphosed urchins from a single spawning event (three males and three females) were highly variable, despite being held en masse under identical environmental and nutritional conditions. As individuals reached ~5 mm diameter (0.07-0.10 g wet weight),...

DMSP-consuming bacteria (DCB) were recovered from the body and fecal pellets of the copepod Acartia tonsa (Dana). The most probable number of DCB associated with starved A. tonsa was 9.2x10(2) cells copepod(-1). The abundance of DCB recovered from the...
