Power Factor Adaptive DPWM Control Strategy for T-Type Three-Level Inverters

Energies
With the widespread application of multilevel inverters, device losses have become a critical area of research. A key limitation of conventional three-level discontinuous pulse width modulation (DPWM) strategies is their inability to maintain switching ...

Crystallization‐Driven Helical Conjugated Polymer Nanowires for Circularly Polarized Light‐Addressable Ferroelectric Physical Unclonable Functions

Small, EarlyView.
Supramolecular helicity meets ferroelectricity: P3HT‐b‐PMMA helical nanowires enable handedness‐specific modulation of remanent polarization in P(VDF‐TrFE) hybrids. This platform demonstrates the first CPL‐addressable ferroelectric PUF, translating molecular chirality into secure digital authentication.

Interface Engineering for Expanded Stable Polarization Regime Upon Cycling in Ferroelectric Hf0.5Zr0.5O2

Small, EarlyView.
Interfaces can be crucial on the properties of ferroelectric HfO2. In this work, it is demonstrated that a top nanolayer of ZrO2 significantly improves the ferroelectric properties of epitaxial La‐doped HfO2 films on SrTiO3(001). Endurance reaches 1011 cycles with a technological window of 108 cycles, in which the remanent polarization variation is ...

PDA‐Engineered 3D‐Printed Polymer–ZrO2 Hybrid Scaffolds Enabling Enhanced Radiopacity, Photothermal Therapy, and Cell Migration Modulation

Small, EarlyView.
A multifunctional 3D‐printed polymer–ZrO2 scaffold is developed to provide intrinsic radiopacity, photothermal responsiveness, and surface bioactivity. Reinforcement with ZrO2 enables real‐time x‐ray visibility and mechanical robustness, while a polydopamine coating facilitates near‐infrared‐triggered drug release and modulates cell migration, thereby ...

Molecularly Regulated Dynamic Interfaces in 3D/2D Perovskites Enabled by Functional Pyridinium Ionic Liquids

Small, EarlyView.
1‐butyl‐4‐methylpyridinium tetrafluoroborate (BMPyBF4) interacts with excess PbI2 during film formation, driving the formation of a low‐dimensional perovskite phase and enabling the self‐organization of a 3D/2D interfacial structure. This molecularly regulated interface suppresses defect‐mediated recombination and facilitates interfacial charge ...

Multi‐State Resistance in Microtubule‐Templated Gold Nanowires

Small, EarlyView.
The scaling limits of CMOS transistors require alternative, dynamically reconfigurable nanoscale devices. This study demonstrates the multi‐state resistance in pure gold nanowires templated by microtubules. Continuous nanowires with local inhomogeneities enable electromigration‐driven, multistate resistance modulation under voltage pulses, while ...
