Mapping the magnetic coupling of self-assembled Fe3O4 nanocubes by electron holography
The nanoscale magnetic configuration of self-assembled groups of magnetite 40 nm cubic nanoparticles has been investigated by means of electron holography in the transmission electron microscope (TEM). The arrangement of ...
Further insights in trichothiodistrophy: a clinical, microscopic, and ultrastructural study of 20 cases and literature review
Background: Trichothiodistrophy (TTD) is a rare autosomal recessive condition that is characterized by a specific congenital hair shaft dysplasia caused by deficiency of sulfur associated with a wide spectrum of multisystem ...
The Bartonian-Priabonian marine record of the eastern South Pyrenean Foreland Basin (NE Spain): A new calibration of the larger foraminifers and calcareous nannofossil biozonation
This study presents a combined biostratigraphic (calcareous nannofossils, larger foraminifers) and magnetostratigraphic study of the Middle and Late Eocene marine units of the Igualada area, eastern Ebro Basin. The studied ...
Applicability of magnetic fabrics in rocks associated with the emplacement of salt structures (the Bicorb-Quesa and Navarrés salt walls, Prebetics, SE Spain)
This work assesses the applicability of the analysis of the anisotropy of magnetic susceptibility (AMS) to rocks associated with salt structures.Magnetic fabrics from16 sites sampled on Upper Triassic clays (Keuper facies) ...
Towards Cellular Ultrastructural Characterization in Organ-on-a-Chip by Transmission Electron Microscopy
Organ-on-a-chip technology is a 3D cell culture breakthrough of the last decade. This rapidly developing field of bioengineering intertwined with microfluidics provides new insights into disease development and preclinical ...
Construction of Zn(II) Linear Trinuclear Secondary Building Units from A Coordination Polymer Based on α-Acetamidocinnamic Acid and 4-Phenylpyridine
The synthesis and characterization of one coordination polymer and two trinuclear complexes are presented. The coordination polymer [Zn2( -O,O'-ACA)2(ACA)2(4-Phpy)2]n (1) has been obtained by the reaction between Zn(OAc)2 ...
Occurrence of a new sulphate mineral: Ca7Na3K(SO4)9 in the Emet borate deposits, western Anatolia (Turkey)
This paper is a preliminary report on the petrographic and geochemical characteristics of a new sulphate mineral associated with lacustrine glauberite layers. This mineral is present in two boreholes recently drilled in ...
A comprehensive characterisation of beer polyphenols by high resolution mass spectrometry (LC-ESI-LTQ-Orbitrap-MS)
Beer is the second most consumed alcoholic beverage in Europe and shown by the European Prospective Investigation into Cancer and Nutrition cohort study to be the main food contributor to hydroxybenzoic acid intake. About ...
Microbial community dynamics in two-chambered microbial fuel cells: effect of different ion exchange membranes
The utilization of different kinds of ion exchange membrane is a common practice in bioelectrochemical systems such as two-chambered microbial fuel cells (MFCs). However, little is known on the effect of the membrane ...

Gut bacterial community of the xylophagous cockroaches Cryptocercus punctulatus and Parasphaeria boleiriana
Cryptocercus punctulatus and Parasphaeria boleiriana are two distantly related xylophagous and subsocial cockroaches. Cryptocercus is related to termites. Xylophagous cockroaches and termites are excellent model organisms ...
Synthesis of Cyclopalladated Derivatives of (E)-N2 Benzylidene-2-(2,6-dichlorophenyl)ethanamine and Their Reactivity towards Monodentate andSymmetric Bidentate Lewis Bases
Treatment of the monoimine (E)-N-benzylidene-2-(2,6-dichlorophenyl)ethanamine (1) with a stoichiometric amount of Pd(OAc)(2) in acetic acid at 60 degrees C under nitrogen produced the corresponding acetato-bridged endo ...

Gene expression following induction of regeneration in Drosophila wing imaginal discs
Background: Regeneration is the ability of an organism to rebuild a body part that has been damaged or amputated, and can be studied at the molecular level using model organisms. Drosophila imaginal discs, which are the ...
Probing the Kinetic and Thermodynamic Fingerprints of Anti-EGF Nanobodies by Surface Plasmon Resonance
Despite the widespread use of antibodies in clinical applications, the precise molecular mechanisms underlying antibody-antigen (Ab-Ag) interactions are often poorly understood. In this study, we exploit the technical ...

In Situ visualization of the local photothermal effect produced on α-CycloNataly Silvadextrin inclusion compound associated with gold nanoparticles
Evidence of guest migration in α-cyclodextrin-octylamine (α-CD-OA) inclusion compound (IC) generated via plasmonic heating of gold nanoparticles (AuNPs) has been studied. In this report, we demonstrate local effects generated ...
Simulation of STEM-HAADF image contrast of Ruddlesden-Popper faulted LaNiO<sub>3</sub> thin films
LaNiO3 (LNO) thin films are widely used as electrode materials. Yet, their properties greatly depend on such parameters as strain state and defect density. In this work we present a detailed structural characterization of ...
Limit to the erbium ions emission in silicon-rich oxide films by erbium ion clustering
We have fabricated a series of thin (~50 nm) erbium-doped (by ion implantation) silicon-rich oxide films in the configuration that mitigates previously proposed mechanisms for loss of light emission capability of erbium ...
