Engineering Polar Nanoregions in COFs via Controlled Symmetry Breaking Toward Piezocatalysis

Angewandte Chemie, EarlyView.
Polar nanoregions (PNRs) are engineered within covalent organic frameworks via asymmetric grafting of highly polar polyfluoroalkyl chains, which enables controlled symmetry breaking. These randomly oriented artificial PNRs dynamically respond to mechanical stimuli and impart relaxation behavior to the COFs (TFB‐TAPT‐FA).

Parametric Analysis of Spiking Neurons in 16 nm Fin Field‐Effect Transistor Technology

Advanced Intelligent Discovery, EarlyView.
Energy efficient computing has driven a shift toward brain‐inspired neuromorphic hardware. This study explores the design of three distinct silicon neuron topologies implemented in 16 nm fin field‐Effect transistor technology. While the Axon‐Hillock design achieves gigahertz throughput, its functional fragility persists. The Morris–Lecar model captures

Light‐Driven Control of Polar Order in Ferroelectric Nematic Liquid Crystals

Angewandte Chemie, EarlyView.
Light‐responsive ferroelectric nematics are achieved by molecularly matching azobenzene photo‐switches to the polar packing motif of DIO. This design yields intrinsically photo‐responsive ferroelectric nematic mesogens and optically addressable DIO blends, in which light reversibly modulates spontaneous polarization and switches between high‐ and low ...

Mirror versus Inversion Symmetry Breaking in Mesogenic Dimers: NTB versus NF Phase

Angewandte Chemie, EarlyView.
Two non‐conventional nematic phases, twist‐bend NTB and ferroelectric NF, are observed within the same homologous series of dimers built of two strongly dipolar mesogenic units linked by a flexible spacer. The type of the phase formed depends on the molecular geometry, defined by parity of internal linkage.

Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation

Advanced Intelligent Systems, EarlyView.
Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired
