Self-Assembly of Zinc Oxide Photonic Crystals in Viscous Liquids: Synthesis, Characterization, and Application to Colored Contact Lenses

Photonics
Structural color is a kind of natural color that widely exists in nature. The ordered microstructure of nano materials can absorb or reflect light of specific wavelength, thus showing colorful colors. Structural color is an ideal choice for color contact

Use of the Visante™ OCT to measure the sagittal depth and scleral shape of keratoconus compared to normal corneae: Pilot study

Journal of Optometry, 2013
Purpose: The purpose of this study is to demonstrate and compare the use of optical coherence tomography (OCT) in measuring sagittal depth (SD) and in describing the corneo–scleral junctions with the use of scleral angles, in a population of keratoconics

Grey Filter Contact Lens as Therapeutic Option for Acquired Reduced Binocular Visual Performance

British and Irish Orthoptic Journal, 2021
Disturbing binocular problems can be too complex to be treated in such a way that comfortable binocular single vision is restored. The grey filter contact lens could offer a safe and clinically useful way to help these patients. Background: In unilateral

Boosting the Energy Density of “Anode‐Free” Lithium Metal Batteries via Electrospun Polymeric Scaffolds

Advanced Functional Materials, EarlyView.
While host structures are known to enhance the reversibility and safety of lithium metal deposition, their additional volume and weight often decrease the battery's energy density and specific energy. By combining a lightweight and porous scaffold of electrospun polymer with a thinner separator, this article demonstrates a simultaneous improvement of ...

Relationship of Peripapillary Retinal Perfusion with Peripapillary Retinal Nerve Fiber Layer Thickness in Diabetes Mellitus Patients without Diabetic Retinopathy

IJRETINA (International Journal of Retina), 2021
Introduction: Impaired blood flow is an early sign of retinal dysfunction in diabetes. Impaired blood flow of the radial peripapillary capillaries can affect the Retinal Nerve Fiber Layer (RNFL) or ganglion cell function.

Biomimetic Iridescent Skin: Robust Prototissues Spontaneously Assembled from Photonic Protocells

Advanced Functional Materials, EarlyView.
Uniform nanoparticles are induced to form arrays (photonic crystals) in the cores of biopolymer capsules, endowing these ‘protocells’ with structural color. These protocells are then assembled into large self‐standing objects, i.e., prototissues, with robust mechanical properties as well as iridescent optical properties.

Increase in choroidal thickness after blue light stimulation of the blind spot in young adults

Bioelectronic Medicine
Background Blue light activates melanopsin, a photopigment that is expressed in intrinsically photosensitive retinal ganglion cells (ipRGCs). The axons of ipRGCs converge on the optic disc, which corresponds to the physiological blind spot in the visual ...
