Future Outlook Toward Heavy‐Metal‐Free Metal Chalcogenide Nanocrystals for Optoelectronic Applications

open access: yesSmall Science, Volume 6, Issue 10, October 2026.
Heavy‐metal‐free chalcogenide nanocrystals are a nontoxic alternative for next‐generation optoelectronic applications. This review provides a comprehensive overview of their unique optical properties, surface chemistry, and their performance in photodetectors, solar cells, light‐emitting diodes, and photocatalytic systems.

Seasonal Variations in Aerosol Trace Element Source Contributions and Deposition Fluxes to the North Pacific Subtropical Gyre

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract Trace elements deposited in the marine environment affect ocean biogeochemistry in numerous, complex ways. This study quantifies seasonal aerosol trace element (TE) fluxes and evaluates their variability and potential sources over a 2‐year period in the North Pacific subtropical gyre (NPSG). We established the Hawaii Aerosol Time Series (HATS),

An Analytical Model for the Spectral Induced Polarization of Metallic Particles Including Stern‐Layer Polarization

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Spectral induced polarization (SIP) is sensitive to metallic grains in geologic materials. Classical diffuse‐layer theory predicts a weaker dependence of relaxation time on electrolyte conductivity than is commonly measured, whereas surface‐capacitance models can reproduce the stronger dependence but do not explicitly resolve the diffuse layer

The Transformation of Trace Metal Distributions Across the Mackenzie Shelf and Through the Northwest Passage

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Understanding the distributions of trace elements, like iron (Fe), manganese (Mn), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), cadmium (Cd), lead (Pb), barium (Ba), and vanadium (V) in the Arctic Ocean is motivated in part because they can modulate key biogeochemical rate processes as micronutrients and/or toxins for primary producers ...
