A Statistical Algorithm for Estimating Chlorophyll Concentration in the New Caledonian Lagoon
Spatial and temporal dynamics of phytoplankton biomass and water turbidity can provide crucial information about the function, health and vulnerability of lagoon ecosystems (coral reefs, sea grasses, etc.). A statistical algorithm is proposed to estimate

Inversion of inherent optical properties in optically complex waters using sentinel-3A/OLCI images: A case study using China\u27s three largest freshwater lakes [PDF]
Inherent optical properties (IOPs) play an important role in underwater light field, and are difficult to estimate accurately using satellite data in optically complex waters.

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

An Optical Reporting Patch for Spatiotemporal Measurements of Water Activity in Complex Environments
Water activity, aw, is an important state parameter in a wide variety of natural and technological contexts. Existing tools to measure water activity in situ and with spatial and temporal resolutions are limited. Here, we present the development of a composite silicone patch, AquaSheet, that reports water activity as a fluorescence signal.

Remote Sensing of Optically Complex Waters - The Multivariate Approach
Optically complex waters, often referred to as case-2 waters, are characterised by the fact that several optically active constituents are present in the water body where the individual concentrations may vary independently of each other. In addition the

Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated
