Zinc Chloride–Polyethylene Oxide Gel Polymer Electrolytes for Wearable and Flexible Energy Storage Applications

Advanced Materials Technologies, EarlyView.
We investigate gel polymer electrolyte ZnCl2‐PEO as energy storage materials in flexible electrochemical capacitors, aiming to provide new insights into energy solutions for low‐powered portable electronics. ABSTRACT We prepared and evaluated the properties of hydrated ZnCl2‐Polyethylene oxide (PEO) gel polymer electrolyte (H‐GPE) for flexible ...

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation

Advanced Optical Materials, EarlyView.
A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.

Basis‐Independent Geometric Phase Modulation in Circularly Birefringent Plasmonic Structures

Advanced Optical Materials, EarlyView.
Here we introduce a plasmonic metasurface composed of spatially rotated chiral spiral unit cells designed to produce space‐variant circular retardance. This generates a geometric phase ramp equivalent to a blazed grating, leading to polarization dependent diffraction orders in momentum space.

Hyperuniform Disorder in Photonic Crystal Slabs With Intrinsic Non‐Hermiticity

Advanced Optical Materials, EarlyView.
Light propagation in photonic crystal slabs with imposed hyperuniform disorder is investigated theoretically and numerically. The hyperuniform disorder is imposed by varying the hole size. The photonic crystal is intrinsically non‐Hermitian due to radiative loss, with non‐Hermiticity appearing as a complex effective mass of a quadratic photonic band ...

From Rigid to Soft Robotic Approaches for Neuroendoscopy

Advanced Robotics Research, EarlyView.
Robotic assistance has had minimal impact on deep intraventricular surgeries, where small‐scale, precision, and reduced invasiveness can contribute to improved patient outcomes. Emerging technologies in rigid, soft, and hybrid robotics are reviewed to identify the most promising mechanisms for deep brain navigation in addition to an attempt to identify
