Clinical signs in cornea and ocular surface

Indian Journal of Ophthalmology, 2018
A careful examination of cornea and ocular surface eliciting the basic signs will help a clinician toward an accurate diagnosis. Flipping the upper lid or pulling the lower lid to look at the inferior fornix may help to pick up any subtle clinical sign ...

Single‐Emitter White OLEDs via Microcavity Spectral Engineering

Advanced Optical Materials, EarlyView.
This research introduces a simple, eco‐friendly approach for fabricating ITO‐free white OLEDs by converting blue emission into broadband white light using microcavity engineering. The emitted color can be adjusted by changing the cavity thickness, offering a scalable method ideal for sustainable lighting applications Abstract White organic light ...

Nanoimprinting of Mesoporous Titania: Direct Patterning and Refractive Index Control in the Visible

Advanced Optical Materials, EarlyView.
Nanoimprinted mesoporous TiO₂ (pTiO₂) films are demonstrated as high‐resolution optical materials with tunable porosity, refractive index, and mechanical response. Sub‐micron patterning of planar optics is shown alongside a refractive index contrast Δn ≈0.7.

Polaritons in Non‐Fullerene Acceptors for High Responsivity Angle‐Independent Organic Narrowband Infrared Photodiodes

Advanced Optical Materials, EarlyView.
High‐performance narrowband NIR organic photodiodes are essential for miniaturized imaging, sensing, and wearable systems, yet existing approaches suffer from angular sensitivity and limited material compatibility. This work demonstrates the first polariton‐enhanced OPDs with angle‐independent response, sub‐45 nm bandwidth, and record responsivity (0 ...

Non-invasive quantification of corneal vascularization using anterior segment optical coherence tomography angiography

Scientific Reports
The presence of corneal vascularization (CV) interferes with the angiogenic and immune privilege of the cornea, risking rejection in eyes following keratoplasty.
