Mesoporous Catalytic‐Adsorptive Nanoregulator Orchestrates Biofilm eDNA/LPS Disassembly and TLR9/TLR4 Immune Reprogramming to Resolve Diabetic Foot Infections

Advanced Science, EarlyView.
Chronic diabetic wounds are hindered by a “dual trap” of biofilm resistance and hyperinflammation. A mesoporous catalytic‐adsorptive nano‐regulator is developed to dismantle this barrier through simultaneous eDNA degradation and LPS sequestration. By silencing TLR4/9‐mediated signaling, the platform clears resilient pathogens and reprograms the immune ...

Ferroelectric Behavior of Micro‐ to Submicron‐Scale HZO Capacitors: Impact of the Perimeter‐to‐Area Ratio

Advanced Electronic Materials, EarlyView.
Using C‐AFM, W/HZO/p‐Ge capacitors with areas down to 0.26 µm2 are investigated. Frequency‐dependent voltage ramps reveal switching currents that confirm complete polarization reversal across the entire electrode area, while PUND enables reconstruction of P–V loops.

Advancing Energy Materials by In Situ Atomic Scale Methods

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Alcohol‐Adduct Mediated Precursor Stabilization Strategies for Conformal SnO2 Layers in Highly Efficient and Stable Perovskite Solar Modules

Advanced Energy Materials, EarlyView.
An alcohol‐adduct‐mediated strategy is employed to stabilize tin isopropoxide for the formation of a homogeneous double electron transport layer (ETL) incorporating SnO2 nanoparticles (NPs). This double‐ETL exhibits improved optical and charge‐transport properties due to reduced defect density and better energy level alignment, resulting in high ...

Lattice Coherency‐Driven (111)‐Oriented Wide Bandgap Perovskite Films

Advanced Energy Materials, EarlyView.
Methylammonium lead chloride (MAPbCl3)‐derived seed templates regulate wide‐bandgap perovskite crystallization through coupled thermodynamic and kinetic effects. Lattice‐coherent templating lowers the energy cost for (111) epilayer growth, while growth retardation controls crystallization kinetics, ultimately producing highly crystalline face‐up (111 ...

Investigation into low power active electromagnetic damping for automotive applications

, 2015
Automobile suspension systems carry out two important functions; road handling and passenger comfort. Hydraulic passive dampers are the most common system employed on vehicles, yet it is well known that passive suspension systems are less effective on ...
