Manganese‐Incorporated Single‐Phase High‐Entropy Oxide Modified Separator Enabled High Performance of Lithium‐Sulfur Batteries at High Sulfur Loading

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study focuses on the fabrication of manganese‐infused high entropy oxides (HEOs) for lithium–sulfur (Li–S) batteries. Incorporating a HEO‐coated Celgard separator at a low material loading (~0.23 mg cm−2), it decreases the HEO content in sulfur composite cathodes, enhancing the catalytic conversion of lithium polysulfides.

Experimental Simulation Investigation on Mechanism and Criterion of Impact‐Induced Rockburst in Gaoloushan Deep Tunnel

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT During the excavation of a deep‐buried tunnel by the drilling and blasting method, the dynamic stress of blasting may cause the disorderly release of high energy in the rock mass during the blasting process of deep high‐energy rock. Blasting vibration is one of the main factors inducing dynamic disasters (such as rockbursts) in the surrounding

Problems of the Metamorphic and Igneous Rocks of the Mojave Desert [PDF]

open access: yes, 1954
The Mojave Desert region, as defined by Baker (1911, pp. 335-336), is the region of desert plains, mountains, and valleys comprising the extreme southwestern portion of the Great Basin (fig. 1).

Worldwide distribution of continental rock lithology: Implications for the atmospheric/soil CO2 uptake by continental weathering and alkalinity river transport to the oceans [PDF]

open access: yes, 2003
The silicate rock weathering followed by the formation of carbonate rocks in the ocean, transfers CO2 from the atmosphere to the lithosphere. This CO2 uptake plays a major role in the regulation of atmospheric CO2 concentrations at the geologic ...

Determination of Groundwater Vulnerability for Protection of the Drinking Water Basins: A Case Study From Türkiye, Kesikköprü Dam Lake Basin

open access: yesGlobal Challenges, EarlyView.
Groundwater vulnerability is evaluated in a critical drinking water basin under the threats of climate change and population growth. Using GIS‐based DRASTIC modeling and field validation, high‐risk zones are identified. The results offer strategic insights for protecting Ankara's groundwater resources against escalating environmental and anthropogenic ...

Reservoir characteristics and hydrocarbon accumulation significance of metamorphic zones of intrusive rocks and surrounding rocks in second member of Paleocene Funing Formation in Qintong Sag, Subei Basin

open access: yesShiyou shiyan dizhi
Volcanic reservoirs play a crucial role in oil and gas exploration. The intrusive rocks in the Qintong Sag of the Subei Basin are widely distributed within active oil and gas deposits, making them a significant area for further exploration and reserve ...

The metamorphic complexes of the Patagonian and Fuegian Andes

open access: yesGeologica Acta, 2008
The Patagonian and Fuegian Andes are made up in part by late Paleozoic to Mesozoic metamorphic complexes. The mostly low grade late Paleozoic Eastern Andes Metamorphic Complex (EAMC) crops out to the East of the Meso-Cenozoic South Patagonian batholith ...
