Nanoplasmonics Reveal Ionic‐Strength‐Driven Hydration of Nanoparticles

Advanced Functional Materials, EarlyView.
Localized surface plasmon resonance (LSPR) of gold nanoparticles (AuNPs) is modulated by ionic‐strength‐dependent hydration shell compression. A predictive model connects shell thickness to non‐radiative damping and spectral shifts over seven orders of magnitude.

Sensitivity of Ocean Carbon Sink Estimates to Rare Observations

Geophysical Research Letters
We evaluate the impact of new data in the annual release of SOCATv2024 on air‐sea carbon dioxide (CO2) flux reconstructions. Using the pCO2‐Residual and LDEO‐HPD methods, we reconstruct surface ocean fCO2 based on SOCATv2023 and SOCATv2024.

Spatial variations in silicate-to-nitrate ratios in Southern Ocean surface waters are controlled in the short term by physics rather than biology [PDF]

Biogeosciences, 2020
The nutrient composition (high in nitrate but low in silicate) of Subantarctic Mode Water (SAMW) forces diatom scarcity across much of the global surface ocean. This is because diatoms cannot grow without silicate. After formation and downwelling at the

Cr3+‐Activated Tunable Near‐Infrared Mechanoluminescence Materials for Potential Water Pollutant Monitoring

Advanced Functional Materials, EarlyView.
Four kinds of magnetite type NIR‐ML materials are synthesized by high‐temperature solid‐state reaction method. The continuous spectral tuning from a sharp R line (698 nm) to a broadband range (650–1000 nm) is realized based on composite engineering, concentration engineering, and lattice engineering strategies.

Antarctic Bottom Water Sensitivity to Spatio‐Temporal Variations in Antarctic Meltwater Fluxes

Geophysical Research Letters, 2023
Ice sheet melting into the Southern Ocean can change the formation and properties of the Antarctic Bottom Water (AABW). Ocean models often mimic ice sheet melting by adding freshwater fluxes in the Southern Ocean under diverse spatial distributions.

Carbon Isotope Constraints on the Deglacial CO2 Rise from Ice Cores [PDF]

, 2012
The stable carbon isotope ratio of atmospheric CO2 (d13Catm) is a key parameter in deciphering past carbon cycle changes. Here we present d13Catm data for the past 24,000 years derived from three independent records from two Antarctic ice cores.
