Atomic Layer Deposition of Disordered p‐Type SnO Using a Heteroleptic Tin(II) Precursor: Influence of Disorder on P‐Channel SnO Thin‐Film Transistor Characteristics

open access: yesAdvanced Electronic Materials, EarlyView.
Disordered p‐type SnO thin‐films are deposited via atomic layer deposition using a novel heteroleptic precursor. These films enable low‐temperature fabrication of thin‐film transistors with excellent stability and mobility. Their potential compatibility with flexible substrates and integration with n‐type IGZO transistors makes them candidates for ...

Spatial and Dynamical Biases in Velocity Statistics of Galaxies

open access: yes, 2003
We present velocity statistics of galaxies and their biases inferred from the statistics of the underlying dark matter using a cosmological hydrodynamic simulation of galaxy formation in low-density and spatially flat cold dark matter cosmogony.

Six months follow up of a single intravitreal injection of ocriplasmin for symptomatic vitreomacular adhesion [PDF]

open access: yes, 2016
Purpose: To evaluate the efficacy and the safety of the enzymatic vitreolysis with a single intravitreal injection of ocriplasmin 125 μg across a group of patients with symptomatic vitreomacular adhesion (sVMA) during 6 months follow up.

Enhanced Resistive Switching Uniformity in Tantalum Oxide Memristor Devices via Copper Implantation

open access: yesAdvanced Electronic Materials, EarlyView.
Metal oxide memristor devices typically suffer from uncontrolled forming processes and limited resistive switching uniformity due to the stochastic formation of an oxygen vacancy filament. Improved resistive switching uniformity in Ta2O5 memristor is developed by Cu implantation in the switching oxide.

Tribología de nuevas capas autolubricantes producidas mediante PVD

open access: yesRevista de Metalurgia, 2005
Las capas de MoS2 depositadas mediante PVD tienen baja fricción en vacío pero se degradan con facilidad al aire, especialmente en presencia de humedad. Este trabajo describe el desarrollo de nuevas capas de MoSx modificadas con WC.

Determinants of fibrinogen in an Italian population suffering from claudication. Lower fibrinogen in the south compared to middle and north of Italy. The ADEP Group. [PDF]

open access: yes, 1998
Prospective studies have shown that high plasma levels of fibrinogen are independently associated with the risk of cardiovascular complications. In patients suffering from peripheral vascular disease (PVD) fibrinogen has been shown to be an independent ...

Multiscale Perspectives on Perovskite Instability: From Atomistic Deformation to Device Degradation in Perovskite Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Multiscale perspectives on how excess charges in soft lead halide perovskites induce operational instability in photovoltaic devices are presented. Localized carriers formed under thermodynamic non‐equilibrium states modify atomistic interactions and drive lattice distortions, accelerating device degradation.

High Capacity Image Steganography Using Modified LSB Substitution and PVD against Pixel Difference Histogram Analysis

open access: yesSecur. Commun. Networks, 2018
The combination of pixel value differencing (PVD) and least significant bit (LSB) substitution gives higher capacity and lesser distortion. However, there are three issues to be taken into account: (i) fall off boundary problem (FOBP), (ii) pixel ...

Atomistic Insights Into Lithium Alloying and Crystallization at Metal Interlayers in Zero‐Excess Lithium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Molecular dynamics simulations with machine learning potentials, combined with experiments, reveal how interlayer metals govern Li alloying and crystallization in zero‐excess lithium batteries. Mg and Zn promote solid‐solution alloy‐mediated pathways that influence Li diffusion and structural uniformity, while Bi forms ordered intermetallics with more ...
