Advanced Materials, EarlyView.Carbon‐based piezoelectric materials are systematically categorized based on their structural and functional properties. The mechanisms of stress‐induced charge transfer are elucidated, and their applications are explored across three key domains: piezoelectric catalysis for energy conversion and environmental remediation, piezoelectric biomedical ...

3-Dimensional Mapping of Corneal Topography and Thickness [PDF]
arXiv, 2003 Optical sections of the cornea are obtained by illumination with a collimated beam expanded in a fan shape by a small rotary cylindrical lens. The light diffused from the cornea is observed by two cameras and processed in order to yield the surfaces' profiles.

Blind De-Blurring of Microscopy Images for Cornea Cell Counting [PDF]
arXiv, 2020 Cornea cell count is an important diagnostic tool commonly used by practitioners to assess the health of a patient's cornea. Unfortunately, clinical specular microscopy requires the acquisition of a large number of images at different focus depths because the curved shape of the cornea makes it impossible to acquire a single all-in-focus image.

Finite element modelling of cornea mechanics: a review.
Arquivos Brasileiros de Oftalmologia, 2014 The cornea is a transparent tissue in front of the eye that refracts light and facilitates vision. A slight change in the geometry of the cornea remarkably affects the optical power.

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.This review focuses on the application of synthetic biodegradable microarray patches (MAPs) in sustained drug delivery. Compared to conventional MAPs which release drugs into the skin in an immediate manner, these implantable MAPs release drugs into skin microcirculation gradually as the biodegradable polymers degrade, thus offering sustained release ...

Inflammation-induced lymphangiogenesis in the cornea arises from CD11b-positive macrophages.
Journal of Clinical Investigation, 2005 In the inflamed cornea, there is a parallel outgrowth of blood and lymphatic vessels into the normally avascular cornea. We tested whether adaptive and/or innate immune cells were actively involved in the genesis of new lymphatic vessels.

Advanced Optical Materials, EarlyView.For an amphibious high‐resolution compound eye vision system, environment‐adaptive self‐aligned waveguides are integrated with high‐density flat microlenses. Fabrication, optical performance, and environmental adaptability are investigated, demonstrating stable focusing, efficient light collection, and enhanced spatial resolution.

In vivo Terahertz Sensing of Skin Cancer Patients
Advanced Photonics Research, EarlyView.This study presents the first in vivo measurements of skin cancer patients in a hospital setting using a handheld THz probe. Furthermore, a new analysis approach is developed to generate a patient‐normalized THz response function, which enables clear contrast to be seen between cancer and healthy skin of the same patient.The first in vivo study of skin

Nearly-incompressible transverse isotropy (NITI) of cornea elasticity: model and experiments with acoustic micro-tapping OCE [PDF]
arXiv, 2020 The cornea provides the largest refractive power for the human visual system. Its stiffness, along with intraocular pressure (IOP), are linked to several pathologies, including keratoconus and glaucoma. Although mechanical tests can quantify corneal elasticity ex vivo, they cannot be used clinically. Optical coherence elastography (OCE), which launches
