Directional Confinement Governed Ion Transport for Efficient Actuation

open access: yesAdvanced Materials, EarlyView.
Structural anisotropy provides an effective means to regulate ion transport in polymer electrolytes. Directionally aligned channels formed by freeze‐drying provide continuous pathways for ion migration, enhancing ion mobility and simultaneously improving the strain and blocking force of ionic actuators.

Thickness‐Defined Transport Regime Toward Near‐Ideal Area‐Type Switching

open access: yesAdvanced Materials, EarlyView.
By thinning the oxide layer, memristors pass from diode‐like and battery‐effect‐dominated behavior toward eventual short‐circuit failure. Within the intermediate 5–6 nm window, they reach a near‐ideal analog area‐type switching regime, featuring symmetric hysteresis, area‐dependent conductance, and continuous linear programming of HRS and LRS with ...

Tear film stability in patients with pterygium and normal healthy subjects: A cross-sectional comparative study.

open access: yes
Background Pterygium is a fibrovascular ocular surface disorder that can disturb tear distribution and produce symptoms of dry eye. Tear film instability is clinically important because it affects ocular comfort, visual quality and surface protection ...

Integrating secretagogues into clinical dry eye care: Insights from Asian clinical experience

open access: yesTaiwan Journal of Ophthalmology
Dry eye is a multifactorial condition characterized by tear film instability, leading to visual disturbances and discomfort. In Asia, clinical management often follows a tear film–oriented approach that emphasizes restoring specific tear components ...

Monolithically 3D‐Printed Spectral‐Spatial Meta‐Authenticators

open access: yesAdvanced Materials, EarlyView.
A single height map printed in a low‐index resin by two‐photon lithography encodes multiple visible wavelengths in one metasurface without any polarization optics. A fabrication‐aware optimization folds the printable height levels into the design, so the device is printed as optimized.

Importance of the lipid layer in providing tear stability

open access: yes
Previous tear film investigations on patients with rheumatoid arthritis (Craig et al., 1995) suggested that a poor meibomian lipid layer on the surface of the tears resulted in tear film instability and could allow increased evaporation of the tears ...
