Characterization of a Volcanic Gas Reservoir Using Seismic Dispersion and Fluid Mobility Attributes

Lithosphere, 2021
Seismic dispersion and fluid mobility attributes are used to characterize a volcanic gas reservoir in the Songliao Basin of China. A rock physics model is constructed to describe poroelastic behaviors associated with heterogeneous fluids saturation ...

The Elvans and Volcanic Rocks of Dartmoor [PDF]

Quarterly Journal of the Geological Society of London, 1889
In the course of an inquiry into the physical history of Dartmoor, which led to the conclusion that this great granitic upland represents the basal portion of a volcano some 16,000 feet high, special attention was necessarily paid to the felsites or elvans of the district, as filling the gap between the plutonic members of the series, the ...

Strong Stabilization of Co Nanoparticles by CeO2‐x Clusters in Inverse CeOx/Co Catalysts for Enhanced CO2 Methanation

Advanced Materials, EarlyView.
Inverse CeOx/Co catalysts are promising new materials for CO2 methanation. Operando spectroscopy reveals that small, reducible CeO2‐x clusters effectively stabilize Co nanoparticles from sintering during H2 reduction and promote CO2 activation at the Co‐CeO2 interface.

A stress-controlled mechanism for the intensity of very large magnitude explosive eruptions [PDF]

, 2011
Large magnitude explosive eruptions are the result of the rapid and large-scale transport of silicic magma stored in the Earth's crust, but the mechanics of erupting teratonnes of silicic magma remain poorly understood.

Clay Reimagined: Phyllosilicates as Future Membrane Technologies

Advanced Materials Interfaces, EarlyView.
Recent advancements in membrane technologies based on 2D materials have drawn attention for molecular‐scale separations owing to these materials’ tunable nanoscale interlayer properties. Phyllosilicates, natural and abundant layered clay minerals, have emerged as scalable and cost‐effective candidates.

Lifespan‐Regulated CAR‐Macrophages from Myeloid Progenitors for Enhanced Colorectal Cancer Therapy

Advanced Science, EarlyView.
Using a tamoxifen‐inducible Hoxb8 system, proliferative bone marrow progenitors can be generated, which are subsequently engineered with an anti‐CEA CAR construct containing a suicide gene (iCas9) and differentiated into CAR‐macrophages. This method facilitates scale up the production of CAR‐macrophages.

The Archaean to Proterozoic igneous rocks of the Pilbara region, Western Australia –internationally significant geology of a globally unique potential geopark

International Journal of Geoheritage and Parks, 2019
The Pilbara region of Western Australia, covering some 500 km × 500 km, provides a diversity of Archaean to Proterozoic igneous rocks in a relatively compact area that records a younging southward crustal history of igneous activity, sedimentation, early
