Spectral Overlap Limits Optical Gain in Quantum Heterostructure Photonic Devices

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
Increasing carrier density is commonly expected to enhance optical gain. Here, a universal crossover is identified in which interaction‐induced spectral broadening competes with the intrinsic energy separation of optical states. When Γavg/Δ approaches unity, spectral overlap suppresses transition selectivity and limits gain, revealing a fundamental ...

Shannon Entropy and Lévy Statistics for Machine Learning‐Assisted Spectral Sensing in Random Fiber Lasers With Magnetic Core–Shell Nanoscatterers

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
Random laser emission was observed in a polymer optical fiber structure doped with magnetic Fe3O4@SiO2 core–shell nanoparticles. A direct relationship was demonstrated between Shannon entropy and Lévy statistics regarding intensity fluctuations in the emission modes. The analysis indicated a potential application in a proposed magnetic field and energy

On–Off Switchable Micromotors for Use in Steerable Microvehicles

Advanced Robotics Research, Volume 2, Issue 4, August 2026.
Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,

Engineering Neuronal Network Connectivity Through Precise and Scalable Electrical Modulation

Advanced Science, Volume 13, Issue 43, 3 August 2026.
This study presents a scalable all‐electrical method for precise neuronal‐circuit reconfiguration based on high‐density microelectrode arrays. By employing biologically inspired plasticity rules, targeted connectivity changes were successfully induced and quantified across diverse neuronal preparations.

Spatial Strategies in Coral Transplantation: A Systematic Review of Clustered Versus Widespread Configurations

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 8, August 2026.
ABSTRACT Active coral reef restoration incorporates ecological engineering principles. Yet, the spatial arrangement of transplanted colonies, one of the few design parameters directly controlled by practitioners, remains poorly explored empirically. We conducted a systematic review following PRISMA guidelines to evaluate how clustered (high‐density ...
