Reliably In‐Memory Ternary Stateful Logic Computing Based on Tri‐State Memristors with High On/Off Ratio

Advanced Electronic Materials, EarlyView.
A tri‐state Ag/Al2O3/Ta2O5/Pt memristor is introduced to in‐memory stateful logic circuits. The stepped I–V characteristics enable the experimental implementations of the ternary logic gates in a crossbar array. The decoder function is demonstrated using cascaded ternary NOT and NOR gates.

Impact of Transition Metals and Electrocatalyst Layer Thickness on the Pt‐Based Cathodes of Proton Exchange Membrane Fuel Cells – Do Multimetallic Electrocatalysts Necessarily Yield an Improved Performance?

Advanced Energy Materials, EarlyView.
Nonnoble transition‐metals (TMs) in PtCuNi/C catalysts have a dual influence in proton‐exchange membrane fuel cell cathode catalyst layer. While TMs act as a “sacrificial component” of PtCuNi/C, inhibiting Pt dissolution from the PtMx nanoparticles bearing the active sites, they promote the formation of separate catalysts and ionomer domains in the ...

Stability of Organic Photovoltaics: From Root Causes to Advanced Analytical Techniques

Advanced Energy Materials, EarlyView.
This review explains the causes and mechanisms of degradation in organic photovoltaics (OPVs). It explores how various factors, including heat, light, oxygen, and inherent material properties, influence OPV stability. The study categorizes degradation pathways and analyzes their impact on device performance, providing insights into the fundamental ...

Autonomous Intuition for Advanced Manufacturing Systems: Benefits and Tradeoffs of Presampling for Autonomous Parameterization

Advanced Intelligent Discovery, EarlyView.
Sampling a design space to target a class of possible desirable outcomes, creating an artificial intuition, can accelerate future optimizations to those targets. This is tested experimentally with parameterization to achieve various geometries of freestanding structures using direct ink write (DIW) 3D printing.

Rapid and Reversible Morphing to Enable Multifunctionality in Robots

Advanced Intelligent Systems, EarlyView.
This article introduces a rapid, reversible, and repeatable morphing robot through a bistable latch‐mediated, spring actuated (LaMSA) mechanism. This enables an untethered, multifunctional robot to near‐instantaneously (< 50 ms) and reversibly switch between a flying and driving configuration to navigate through different environments.
