Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

Advanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Exploring Dipolar Dynamics and Ionic Transport in Metal‐Organic Frameworks: Experimental and Theoretical Insights

Advanced Functional Materials, EarlyView.
In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

Advanced Functional Materials, EarlyView.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Ferrocene Derivatives Enable Ultrasensitive Perovskite Photodetectors with Enhanced Reverse Bias Stability

Advanced Functional Materials, EarlyView.
Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

Ab Initio Study on 3D Anisotropic Ferroelectric Switching Mechanism and Coercive Field in HfO2 and ZrO2

Advanced Functional Materials, EarlyView.
This study uncovers a new switching mechanism in HfO2 and ZrO2, where the absence of a non‐polar layer along the a‐direction induces interaction between polar layers. Consequently, the switching barriers for growth are lower than those for nucleation in this direction, leading to a size‐dependent coercive field that matches experimental observations ...

Synchrotron Radiation for Quantum Technology

Advanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.

Determinación de la participación de la corteza auditiva en los cambios inducidos por estimulación auditiva en el patrón electroencefalográfico de supresión cortical (CS)

, 2019
La supresión cortical (SC) es un patrón electroencefalográfico que puede ser inducido por anestesia general con isoflurano, se caracteriza por periodos de supresión interrumpidos por periodos de alta amplitud y baja frecuencia (ráfagas). La relación entre estos periodos (BSR) puede ser modificada por estimulación externa, las ráfagas pueden ser ...

Autopercepção no Rorschach-SC de idosos com depressão em uma perspectiva idiográfica = Self-perception in the Rorschach-CS of the elderly with depression in a idiographic perspective = Autopercepción en el Rorschach-SC de los ancianos con depresión en una perspectiva idiográfica

Psico, 2019
O uso de instrumentos de autoexpressão pode trazer contribuições na apreensão do trabalho mental. Este estudo propõe avaliar a autopercepção no Rorschach-SC de idosos com depressão em uma perspectiva idiográfica. Foram analisados 31 protocolos de idosos entre 60 e 86 anos de idade, 29 mulheres e dois homens.
