Enhancement of Modulation Bandwidth for VLC Utilizing Green Mini‐LED Light Source

open access: yesAdvanced Physics Research, EarlyView.
This paper investigates three sizes of green Mini‐LEDs for visible light communication, focusing on modulation bandwidth and the impact of atomic layer deposition (ALD) sidewall passivation. ALD significantly enhances bandwidth (up to 21.6%), confirming suppression of nonradiative recombination.

The tiger salamander as a promising alternative model organism to the axolotl for fracture healing and regenerative biology research

open access: yesThe Anatomical Record, EarlyView.
Abstract Scientists have been captivated by the ability to regenerate, focusing on uncovering the mechanisms of epimorphic regeneration and applying them to human medicine. The axolotl (Ambystoma mexicanum) has become the most intensively studied model in tetrapod regeneration research, particularly concerning limb regeneration.
