Energy‐Resolved Femtosecond Dynamics of Plasmon‐Induced Hole Injection at Au/GaN Heterointerfaces

Advanced Science, Volume 13, Issue 33, 15 June 2026.
We reveal the spectral signature of ultrafast nonthermal hot‐hole transfer at plasmonic heterointerfaces, which reshapes hot‐carrier relaxation dynamics and significantly enhances hydrogen evolution, providing a mechanistic basis for optimizing hot‐carrier utilization in photocatalysis.

Gecko‐Like Multi‐Directional High‐Power Magneto–Mechano–Electric Energy Harvesters for Self‐Powered, Hundred‐Meter‐Scale LoRa Communication

Advanced Science, Volume 13, Issue 32, 9 June 2026.
Gecko like multi directional high power magneto mechano electric energy harvester (MME EH) for self powered, hundred meter scale LoRa communication. Inspired by the symmetric and flexible limb motion of geckos, the biomimetic harvester enables coordinated bending twisting responses to weak, low frequency (50/60 Hz) stray magnetic fields from power ...

Maximum likelihood sequence estimation for optical complex direct modulation.

Optics Express, 2017
Semiconductor lasers are versatile optical transmitters in nature. Through the direct modulation (DM), the intensity modulation is realized by the linear mapping between the injection current and the light power, while various angle modulations are ...

Controls on Valley‐Floor Width in the Western Andes

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract River‐valley floors are low relief, confined parts of the landscape that store sediment en route from mountains to lowlands. Transient sediment storage influences sediment budgets, biogeochemical cycles, and the preservation of environmental signals. The controls on valley‐floor width remain poorly understood, limiting the ability to reproduce

Deep Learning Enabled Ultrafast Optical Spectral Phase Retrieval via Unbalanced‐Intensity Autocorrelation

Nanophotonics, Volume 15, Issue 10, 27 May 2026.
Phase‐enabled nonlinear gating with unbalanced intensity (PENGUIN) enables reconstruction of the complete ultrafast optical field from one‐dimensional nonlinear interferometric autocorrelation traces. Combined with deep learning, the DeepPENGUIN framework enables real‐time spectral phase retrieval without spectrally resolved detection or iterative ...
