鄂尔多斯盆地姬塬地区长6 储层矿物含量与孔隙度的线性关系 [PDF]

, 2019
矿物含量是影响储层物性的重要因素之一。为了较全面地分析不同类型矿物含量对储层孔隙度的影响，以鄂尔多斯盆地姬塬地区长6 砂岩储层为例，探索性地运用多元逐步线性回归法分析了石英含量（x1）、长石含量（x2）、岩屑含量（x3）、绿泥石含量（x4）、伊利石含量（x5）、高岭石含量（x6）、硅质含量（x7）以及铁方解石含量（x8）与孔隙度（y）的关系，建立了矿物含量（xi）与孔隙度（y）之间的回归模型：y = 21.131-0.086 x2-0.113 x3-0.554 x4-0.370 x5-0.199 x6 ...

Mechanistic Investigation of Salt Precipitation Induced by Supercritical CO2 in Saline Aquifers

Water Resources Research, Volume 61, Issue 10, October 2025.
Abstract Salt precipitation near injection wells critically influences both the efficiency and integrity of CO2 geological storage in saline aquifers, especially under high‐salinity conditions. To clarify the dominant mechanisms of supercritical CO2 (ScCO2)‐induced salt crystallization and inform mitigation strategies, we conducted static high ...

Ultra‐High‐Capacity of Earth‐Abundant Cathodes Enabled by Excess Fluoride‐Ion Insertion/Extraction

Advanced Energy Materials, Volume 15, Issue 29, August 5, 2025.
A perovskite oxyfluoride SrFeO2Fx can accomodate excess F– beyond x = 1 in the structure with oxygen redox (O–O bond formation). The Sr‐substituted CaFeO2Fx (Ca0.8Sr0.2FeO2Fx) provides an extremely large capacity of 580 mAh g−1 (2595 mAh cm−3). This research will provide new design principles for the development of all‐solid‐state fluoride‐ion battery ...

Exit from Exit Resetting the Cell Cycle through Amn1 Inhibition of G Protein Signaling [PDF]

, 2003
In S. cerevisiae cells undergoing anaphase, a ras-related GTPase, Tem1, is located on the spindle pole body that enters the daughter cell and activates a signal transduction pathway, MEN, to allow mitotic exit.

Recovery of lacustrine ecosystems after the end-Permian mass extinction [PDF]

, 2020
The end-Permian mass extinction (EPME; ca. 252 Ma) led to profound changes in lacustrine ecosystems. However, whether or not post-extinction recovery of lacustrine ecosystems was delayed has remained uncertain, due to the apparent rarity of Early and ...

The Role of MCPIP1 in Macrophage Polarization and Cardiac Function Post‐Myocardial Infarction

Advanced Science, Volume 12, Issue 25, July 3, 2025.
Following myocardial infarction, MCPIP1 deficiency in macrophages triggers ferroptosis, driving proinflammatory M1 dominance over reparative M2 phenotypes. This imbalance amplifies splenic monocyte release and sustains cardiac inflammation. Concurrently, excessive inflammatory mediators and insufficient TGF‐β impair fibroblast activation, delaying ...
