Early Cretaceous–Late Miocene Basin–Mountains Pattern in the Northeastern Margin of the Tibetan Plateau, NW China: Evidence From Detrital Zircon Chronology in the Lanzhou Basin

Geological Journal, EarlyView.
Using DZmix and DZstats models, we quantified the contributions of potential sources of the Lanzhou basin. Our findings indicate that the Cenozoic cooling and denudation signals primarily originated from Qilian and West Qinling, which were the main sediment sources.

Neoarchean Arc Magmatism and Crust Recycling in the Northern Marginal Zone of the Limpopo Complex, Zimbabwe: New Insights From Zircon U‐Pb‐Hf Isotopes of a Charnockite Suite

Geological Journal, EarlyView.
Charnockites with 2691–2607 Ma magmatic ages from the NMZ show arc‐magmatic geochemical signatures. They correspond to the lower‐crustal equivalent of the Chilimanzi Suite Granite in the Zimbabwe Craton. Lu‐Hf isotopic data of magmatic zircons show negative εHf(t) values (−11.18 to −2.20) with TDMC ages of 3699–3158 Ma, suggesting their protolith ...

Ruthenium Nanozyme@Magnesium silicate nanosheets encapsuled in microneedle patches promote repair of radiation‐induced skin defects by remodeling pathological environment

Interdisciplinary Medicine, EarlyView.
In this work, we introduce a novel composite microneedle (MN) patch that integrates ruthenium‐loaded magnesium silicate nanosheets (MSR) as a multifaceted therapeutic platform with oxidative stress mitigation, ROS generation inhibition and cellular signaling pathways restoration for treating RISD.

Combining Density Fractionation and Ca K‐Edge XANES Reveals Contrasting SOM–Mineral Association Patterns Shaped by Parent Material in Forest Soil O Horizons

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Soil organic matter (SOM) accumulation in forest soils is strongly influenced by interactions with inorganic constituents derived from parent material mineralogy. However, their role in the forest floor remains underexplored.

Determining Exchangeable Base Cations in Forest Soils: A Comparison of Three Methods

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Accurately determining exchangeable base cations is critical for assessing base cation depletion in acid forest soils, where various extraction methods may yield different results. Aim The aim was to quantify differences in the effectiveness of BaCl2, NH4OAc (pH 7), and Cohex methods in extracting base cations from acid forest soils

THE HYDRATION OF DICALCIUM SILICATE AND TRICALCIUM SILICATE

Canadian Journal of Research, 1936
Samples of β-dicalcium silicate, γ-dicalcium silicate, tricalcium silicate, hillebrandite and dehydrated hillebrandite were exposed to saturated steam at temperatures between 50° and 375 °C. After drying to constant weight (usually over calcium oxide) the increase in weight and the amount of free calcium hydroxide were determined.

Silicate Urolithiasis

Journal of Urology, 1984
Urinary tract silicate calculi are rare. Occurrence is limited strictly to patients who ingest magnesium trisilicate antacids. We report a case of a renal silicate calculus and review the subject of silicate stones.
