Unraveling the Effects of Depolarization in Ultrathin Barium Titanate
Advanced Science, EarlyView.This article employs synchrotron‐based spectroscopy, time‐resolved electrical measurements, and phase‐field simulations to establish reverse‐domain formation as the mechanism of polarization loss in ultrathin BaTiO3${\rm BaTiO}_3$ films as a critical obstacle to low‐voltage ferroelectric devices.

Advanced Science, EarlyView.Diabetic bone defects remain a critical clinical challenge. A 3D‐printed BCPG‐MF@Y scaffold, embedding Yoda1‐functionalized manganese dioxide‐ferritin nanozymes, scavenges mtROS, suppresses the cGAS–STING pathway, and reverses cellular senescence, while Yoda1 activates Piezo1 to direct BMSCs fate to synergistically reprogram the osteoimmune ...

Design and characterization of a tunable polarization-independent resonant grating filter
, 2005 We present the design, analysis and characterization of a polarization-independent tunable resonant grating filter. Polarization independence is achieved by setting the plane of incidence parallel to the grating grooves and optimizing the fill factor to ...

Intrinsic i$i$‐Wave Altermagnetism in 2D Graphene Superlattices
Advanced Science, EarlyView.Altermagnetism has so far been mostly proposed in transition metals compounds. Here we show that monolayer and bilayer graphene antidot superlattices realize a carbon‐based i‐wave altermagnet. This is demonstrated with a combination of symmetry analysis, first principles methods and effective models, featuring a six‐fold spin splitting texture in ...

Generation and characterization of polarization scrambled optical signals [PDF]
, 2012 Controlling the state of polarization of a light beam of an optical fiber is of crucial importance. Non-Linear Polarization Pulling (NLPP) is an all-optical way to control the state of polarization of signals which has been proposed in recent years ...
