Temporal methane dynamics in the surface waters of a stratified eutrophic lake over four years

open access: yesLimnology and Oceanography, EarlyView.
Abstract The occurrence of oxic methane production (OMP) has been reported for numerous aquatic ecosystems. Its seasonal dynamics and contribution to global methane (CH4$$ {\mathrm{CH}}_4 $$) emissions remains uncertain, however, due to the lack of measurements constraining the spatial and temporal variability of OMP.

Programmable Dual‐Wavelength Switchable All‐fiber Laser via Hybrid Optical Amplifier in the NIR‐III Region for Multi‐Contrast Photoacoustic Microscopy

open access: yesLaser &Photonics Reviews, EarlyView.
A novel dual‐wavelength switchable all‐fiber laser operating in the NIR‐III region, utilizing a hybrid optical amplifier, is presented. This laser generates high power‐spectral‐density pulses with flexible pulse widths and high switching frequencies, enabling efficient multi‐contrast photoacoustic microscopy for the detection of microplastics in ...
