Macromolecular Condensates as Tunable Scaffolds for Bio‐Inspired Silica Hybrids

Angewandte Chemie, Volume 138, Issue 14, 27 March 2026.
Dense bio‐inspired silica formation is achieved by coupling polyamine liquid–liquid phase separation with pH‐dependent silica polymerization. Silicification within polyamine condensates, enables precise control over particle size, density, and morphology.

When do we need pan-global freeze to explain ^(18)O-depleted zircons and rocks? [PDF]

, 2011
Rocks with δ^(18)O values of less than 5‰ SMOW (Standard Mean Ocean Water) contain oxygen derived from ∼0‰ seawater or meteoric (rain or melted snow,

Thermal Buffering, Heat Advection and Crustal Thinning in the Ryoke Metamorphic Complex, Yanai, Southwest Japan

Journal of Metamorphic Geology, Volume 44, Issue 4, Page 287-310, May 2026.
ABSTRACT The metamorphic zoning and geothermobarometry of the Ryoke metamorphic complex in the Yanai area, southwest Japan, show that its thermobaric structure was buffered by the dehydration melting of biotite. The temperatures over most of the area covered by the three high‐grade zones (8.5‐ to 19.0‐km depth) are consistent with those of the ...

Marine Volcaniclastic Record of Early Arc Evolution in the Eastern Ritter Range Pendant, Central Sierra Nevada, California

Geochemistry, Geophysics, Geosystems, 2018
Marine volcaniclastic rocks in the Sierra Nevada preserve a critical record of silicic magmatism in the early Sierra Nevada volcanic arc, and this magmatic record provides precise minimum age constraints on subduction inception and tectonic evolution of ...

High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.

Identifying the Extent of River‐Influenced Waters of the Transpolar Drift With In Situ Measurements of Dissolved Organic Matter Fluorescence and Seawater Density

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The oceanic component of the Transpolar Drift (TPD) is a key component of Arctic Ocean surface circulation. However, our understanding of its spatial extent and influence on the underlying water column remains limited. This study leverages a unique high spatial resolution oceanographic transect from August 2022 (late summer), first to identify

Fractal Dimensions of Venusian Lava Flows: New Findings for Atla Regio and Review of Previous Analyses

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract The fractal dimensions of lava flow margins on Earth often correlate with their flow morphologies and have been used to tentatively identify flow morphology on other rocky planets where fine‐scale observations are limited. Previous studies of lava flow margins on Venus have reported fractal dimensions (D) mostly within the range between 1.05 ...
