Challenges in Simultaneous Microstructuring and Hyperdoping of Germanium with Ultrafast Laser
physica status solidi (a), Volume 223, Issue 8, 22 April 2026.Femtosecond laser processing is explored as a single‐step route to microstructure and hyperdope germanium for extended infrared absorption. Comparative experiments with and without a Ti precursor reveal that Ge's shallow green light absorption and low thermal conductivity drive intense localized melting, evaporation, and redeposition. Post‐cleaning and

Respiration Rates in the Global Mesopelagic Ocean
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Respiration in the mesopelagic layer of the oceans (200–1,000 dbar) is a key factor controlling the biological carbon pump, as it attenuates the downward flux of organic carbon to the ocean interior. Using a global data set of dissolved oxygen and transient tracer gas measurements, we report spatially resolved oxygen utilization rates (OUR ...
