An ultraviolet–visible spectroscopy system for studying real‐time pressure effects on enzyme activity

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Investigations of hydrostatic pressure effects on microbial enzymatic processing are challenging but critical for understanding element cycling in the world's oceans. In this study, we developed and tested a stainless‐steel pressure cell capable of withstanding up to 110 MPa of hydrostatic pressure (equivalent to ~ 11,000 m depth), featuring ...

Deep‐UV Photonic Crystal Surface‐Emitting Lasers

open access: yesLaser &Photonics Reviews, EarlyView.
The first deep‐UV photonic crystal surface‐emitting lasers (PCSELs) at 279 nm are demonstrated under pulsed optical pumping. The PCSELs have single‐mode emission with a 17‐pm linewidth and a divergence angle of less than 1∘$^{\circ }$. Experimental results highlight the impact of the filling factor choice on the lasing mode and the far‐field emission ...
