Advanced Functional Materials, EarlyView.In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Advanced Functional Materials, EarlyView.Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...

Advanced Functional Materials, EarlyView.Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Physical model for electroporation of cell membranes
AIP AdvancesBy treating the human cell structure as a layered dielectric capacitor, a physical model has been developed for the electroporation of cell membranes. It is shown, from dielectric physics and using Gibbs potential/free-energy principles, that hydrogen ...

Orbital Geometry‐Governed Response of Pressure‐Tunable Quantum Defects in hBN
Advanced Functional Materials, EarlyView.Defects in hBN act as ultrasensitive quantum manometers when the energy of the intradefect optical transitions is modified by lattice compression. The orbital geometry of the electron wave functions governs how electron hopping and Coulomb interactions react uniquely to the reduction of the van der Waals gap and in‐plane compression, leading to robust ...

A study of the effect of electrical breakdown in dielectric liquids on the needle point structure
, 1993 It has been suggested that the radius of curvature of needle point influences the electrical breakdown process. Optical microscope studies of the effect of consecutive breakdowns on the shape of steel needles in dielectric liquids have been performed ...

Dielectric barriers under lightning impulse stress: Breakdown and discharge-dielectric interaction in short non-uniform air gaps [PDF]
, 2019 Dielectric-air insulation systems can reduce the carbon footprint of medium voltage switchgear, as they can replace SF6-insulated systems. Such replacement is, however, not easy, as the devices are typically compact and complex, with strongly ...

Advanced Functional Materials, EarlyView.Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights
