OcuPair, a Novel Photo‐crosslinkable PAMAM Dendrimer‐Hyaluronic Acid Hydrogel Bandage/Bioadhesive for Corneal Injuries and Temporary Corneal Repair

open access: yesAdvanced Science, EarlyView.
A schematic diagram showing the OcuPair adhesive hydrogel formulation loaded into the final delivery device and applied over the full‐thickness corneal wound in an in vivo rabbit model of corneal injury followed by in situ crosslinking to form a transparent hydrogel bandage sealing the wound.

To Upgrade a Telescope? [PDF]

open access: yesSymposium - International Astronomical Union, 1974
The effectiveness of existing telescopes can often be greatly enhanced through upgrading. Two important questions which should be answered in the planning stage are discussed, based on recent experience in upgrading two Lowell Observatory telescopes.

A correction method of encoder bias in satellite laser ranging system

open access: yesGeodesy and Geodynamics, 2013
In a satellite laser ranging telescope system, well-aligned encoders of the elevation and azimuth axes are essential for tracking objects. However, it is very difficult and time-consuming to correct the bias between the absolute-position indices of the ...

A Review of Ga₂O₃ Heterojunctions for Deep‐UV Photodetection: Current Progress, Methodologies, and Challenges

open access: yesAdvanced Electronic Materials, EarlyView.
This paper provides a comprehensive review of the existing literature related to the fundamentals of gallium oxide (Ga2O3), growth methods, substrates, and particularly a focused examination of Ga2O3‐based heterojunctions. Particular attention has also been given to the state‐of‐the‐art Ga2O3‐based heterojunctions for photodetectors. The key challenges

The Melbourne Telescope [PDF]

open access: yesNature, 1872
MR. ELLERY has been so good as to send me an enlargement of the lunar photograph taken with the great Melbourne telescope, to which you allude at p. 228, No. 142 of your Journal. This picture, Mr. Ellery tells me, was taken on the second evening of trial; it is very beautiful, although not so critically sharp as several I have obtained with my ...

SST-GATE: A dual mirror telescope for the Cherenkov Telescope Array [PDF]

open access: yes, 2013
The Cherenkov Telescope Array (CTA) will be the world's first open observatory for very high energy gamma-rays. Around a hundred telescopes of different sizes will be used to detect the Cherenkov light that results from gamma-ray induced air showers in ...

Determining Exciton Diffusion Length in Organic Semiconductors: Unifying Macro‐ and Microscopic Perspectives

open access: yesAdvanced Energy Materials, EarlyView.
Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...

Imaging Parhyale hawaiensis embryogenesis with frequency domain photoacoustic microscopy: A novel tool in developmental biology

open access: yesJournal of Biophotonics, Volume 15, Issue 12, December 2022., 2022
We introduce a novel, low‐cost photoacoustic microscope, which is capable of listening to the laser light interactions with developing embryos of Parhyale hawaiensis emerging model organism. The presented label‐free imaging approach delineates the morphological features of the specimens with high resolution and contrast specificity, shedding light on ...

A Physics‐Informed Neural Network as a Digital Twin of Optically Turbid Media

open access: yesAdvanced Intelligent Systems, EarlyView.
In this work, a physics‐informed neural network is presented as a digital twin for modeling and studying optically turbid media without requiring reference light. The model learns and integrates complex wavefront modulation behavior, ensuring robustness without explicit calibration.
