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

Limnology 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 ...

Reaction kinetics of ultracold molecule-molecule collisions

Nature Communications, 2018
Chemical few-body reactions at ultralow temperatures exhibit scaling laws which are directly linked to the nature of the involved particles and their interactions. Here, the authors investigate the kinetics of four-body collision processes where diatomic

Recent Advances in Photonic Bound States in the Continuum: From Fundamentals to Engineering and Implementation

Laser &Photonics Reviews, EarlyView.
This review summarizes recent progress in meta‐photonics with a focus on bound states in the continuum (BICs) as a powerful platform for light confinement and control. It covers fundamental concepts, design strategies across optical regimes, symmetry breaking for practical quasi‐BICs, tunable and AI‐assisted BIC devices, and emerging applications in ...

The effects of seasonality and parasitism on diet and habitat selection in the common periwinkle

Oikos, EarlyView.
The common periwinkle Littorina littorea is an ecologically important grazer, known for its strong influence on algal communities and its role in structuring ecosystems. It serves as the first intermediate host for several trematode species in the Baltic Sea, especially for the fluke Cryptocotyle lingua.

Deep Proteomic Profiles of the Antarctic Diatom Fragilariopsis Cylindrus Under Varying Iron and Manganese Conditions

PROTEOMICS, EarlyView.
ABSTRACT Fragilariopsis cylindrus is a key diatom in the Southern Ocean, where low iron and manganese availability constrain primary production and biogeochemical activity. The molecular mechanisms used by polar diatoms, including F. cylindrus, to cope with trace metal limitations remain largely unexplored.

Collaborative Sampling and Imaging of Phytoplankton Communities by Two Long‐Range Autonomous Underwater Vehicles Using Acoustic Tracking and Messaging

Journal of Field Robotics, EarlyView.
ABSTRACT Collaborative operation of multiple autonomous underwater vehicles (AUVs) can effectively achieve scientific goals that are hard to achieve by independently operated vehicles. Some science payloads are large, expensive, and need to be installed in the vehicle's nose cone. A vehicle can only carry one such payload.
