Corrigendum to ‘‘The effect of surface treatment on CaP deposition of Ti6Al4V open cell foams in SBF solution.’’ [Ceram. Int. 39 (2010) 1805–1816]

open access: yes, 2011
The authors regret that they accidentally omitted to refer to Prof. A.C. Tas, who originally found the SBF solution used in the experiments. The corrections to the affected sentences are listed below.

Kinetic‐Directed Thermodynamic Repair Enables the Synthesis of High‐Strain 2D Sub‐Stoichiometric COFs

open access: yesAdvanced Science, EarlyView.
2D covalent organic frameworks are promising photocatalysts. Yet, precise synthesis of sub‐stoichiometric COFs remains challenging due to poor kinetic control. We propose a general strategy: tuning polymerization degree of kinetic intermediates via time or solvent polarity directs their thermodynamic repair into highly crystallization. Using [4+3]‐type

The Regional Economic Effects of Immigration [PDF]

open access: yes
The effects of immigration on the host country are pervasive and long-term. It is not surprising that they have been extensively analysed, not least the economic effects which have been the subject of both theoretical and empirical research.

Optical Charge Trap Memory Based on Graphene/ZnO Heterostructures for Long‐Term Retention and Adaptive Learning

open access: yesAdvanced Electronic Materials, EarlyView.
A biocompatible graphene/ZnO optical charge trap memory (CTM) is reported with over 54 h retention, enabled by interfacial photodoping. Using transient absorption spectroscopy and electrical analysis, charge transfer quenching is elucidated and reveal that a large energy barrier at the interface is responsible for long‐term memory retention.

Non‐Destructive, Reference‐Free Quantitative Analysis of TaOx Memristive Devices Using Soft X‐Ray Radiation

open access: yesAdvanced Electronic Materials, EarlyView.
A non‐destructive, quantitative approach has been developed to explore the nanoscale dynamics of TaOx‐based memristive devices. The utilization of nano‐X‐ray fluorescence analysis enables the direct probing of spatially resolved elemental distributions, including those present in buried layers, that are critical for the resistive switching.

Dystonia Versus Redox Balance: A Preliminary Assessment of Oxidative Stress in Patients

open access: yesAntioxidants
Dystonia is defined as a movement disorder, the etiology of which may be linked to oxidative stress. The objective of this study was to evaluate the serum levels of zinc, copper, and selenium, as well as oxidative stress parameters, in patients diagnosed

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.
