Dolomite geochemistry of the Cambrian Longwangmiao Formation, eastern Sichuan Basin: Implication for dolomitization and reservoir prediction

Petroleum Research, 2017
Based on petrology and mineralogy, the geochemical characteristics of dolomite in the Cambrian Longwangmiao Formation in the eastern Sichuan Basin, were carried out. Results showed that dolomites mainly occurred in the middle and upper parts of Longwangmiao Formation, with most commonly as a crystalline dolomite and less commonly as a gain dolomite ...

Cryogen‐Aided Chromatographic Purification of Millimole Quantities of Methane for Spectroscopic Clumped Isotope Analysis

Rapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale Quantum cascade laser absorption spectroscopy (QCLAS) is a fast and reliable method for analyzing the bulk (𝛿13C‐CH4, 𝛿D‐CH4) and clumped isotopic (∆13CH3D and ∆12CH2D2) composition of methane. However, precise measurements of ∆12CH2D2 require 0.5 to 1.8 mmol of purified methane (equivalent to 15 to 40 mL at STP).

A Copper‐Complexing Lipid Unmasks the Ethanol Hidden Within Liposomes and Highlights the Relevance of Fabrication Method on the Performance of Lipophilic Functional Molecules

Small Science, Volume 6, Issue 8, August 2026.
Liposomes of the same composition obtained with microfluidics (μF) and thin film hydration methods exhibit different physicochemical properties, due to residual traces of ethanol from the μF protocol. This affects the insertion of a synthetic lipophilic ligand (HIOTD) and its ability to complex Cu(II).

Classification and Conceptualization of Karst Recharge Processes Through Spectral and Change Point Analysis of Drip Water Dynamics

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Karst aquifers are notoriously heterogeneous, making it challenging to characterize recharge dynamics using traditional, static indicators. Percolating (drip) water records, when analyzed at high temporal resolution, offer insights into flow mechanisms in karst vadose zones.
