Thermally Pre‐Formed Reconfigurable Resistive Random‐Access Memory Crossbar Arrays: A Dual‐Mode Platform for Robust Physically Unclonable Functions and In‐Memory Computing

open access: yesAdvanced Functional Materials, EarlyView.
A reconfigurable RRAM platform utilizing thermally pre‐formed filaments (TPFs) is developed to realize robust hardware security. By exploiting the thermodynamic stochasticity of TPFs, exceptionally reliable physically unclonable functions (PUFs) are achieved.

Atomized Oxidative Polymerization as a 3D Printing Platform for Binder‐Free, Bulk Conductive Polymer Architectures

open access: yesAdvanced Functional Materials, EarlyView.
Co‐delivery of electrosprayed EDOT and oxidant enables bulk oxidative polymerization during layer‐by‐layer fabrication, creating stable, highly conductive 3D PEDOT structures. This Atomized Oxidative Polymerization (AOP) overcomes the surface deposition‐only and matrix‐limited conductivity of conventional Vapor Phase Polymerization (VPP) and PEDOT:PSS ...

Support‐Controlled Reaction Pathways via Dynamic Sulfur‐Mediated Interfaces for Selective Urea Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
Sulfur‐doped graphitized carbon nanofibers act as adaptive catalyst–support platforms, enabling dynamic sulfur‐mediated reconstruction and strong metal–support interactions. This unique behavior enhances catalyst stability and controls reaction pathways, achieving highly selective urea oxidation (∼92% N2) coupled with efficient hydrogen evolution ...

Chemical composition of volatile components of Capsicodendron dinisii Schwancke (Canellaceae) [PDF]

open access: yes, 2010
The volatile components of the stem bark of Capsicodendron dinisii were obtained by hydrodistillation using a modified Clevenger-type apparatus. The chemical compounds were identified using the arithmetic index and confirmed by GC-MS.

Nano‐Scale Characterization of Impurities Segregation in Solid Oxide Electrolysis Cells

open access: yesAdvanced Functional Materials, EarlyView.
Cathodic polarization induces impurity segregation in Ni, forming an amorphous Na─Al─Si─O amorphous phase at grain boundaries. Under ultralow oxygen partial pressure, multiple elements dissolve, migrate, and reoxidize within the metal. A patterned model system provides direct nanoscale evidence, clarifying the mechanism of polarization‐driven impurity ...
