The shale oil and gas exploration potential of the Jurassic Qianfoya Formation in the Sichuan Basin is promising. However, there is still a lack of understanding regarding the basic sedimentary characteristics and development patterns of fine-grained ...

A preliminary study on the Earth’s evolution and condensation
Through many field geology observations, the authors find that sandstone and carbonate rocks, which were originally thought to be sedimentary, have magmatic characteristics and should classified as magmatic rather than sedimentary rocks.

Evolution of major sedimentary mounds on Mars [PDF]
We present a new database of $>$300 layer-orientations from sedimentary mounds on Mars. These layer orientations, together with draped landslides, and draping of rocks over differentially-eroded paleo-domes, indicate that for the stratigraphically-uppermost $\sim$1 km, the mounds formed by the accretion of draping strata in a mound-shape.

Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Tunable Thermoshrinkable Hydrogels for 4D Fabrication of Cell‐Seeded Channels
A thermoresponsive polymer with methacrylate groups for photo‐cross‐linking, based on polyethylene glycol, N‐isopropylacrylamide, and 2‐hydroxyethyl acrylate is synthetized to yield hydrogels that shrink upon temperature increase. The new polymer enables the fabrication of cell‐laden perfusable channels with diameters below 200 µm by combining ...

Early Cenozoic denudation of central west Britain in response to transient and permanent uplift above a mantle plume [PDF]
Upwelling mantle plumes beneath continental crust are predicted to produce difficult to quantify, modest uplift and denudation. The contribution of permanent and transient components to the uplift is also difficult to distinguish.

NeoCast is a next‐generation, solvent‐free, non‐adhesive liquid embolic designed for indications where deep occlusion is desired (e.g., tumors and chronic subdural hematoma). This novel agent offers ideal embolic properties: injectability, controllability, excellent visibility, and biocompatibility.

Mechanistic Links Between the Sedimentary Redox Cycle and Marine Acid-Base Chemistry [PDF]
The redox state of Earth's surface is controlled on geological timescales by the flow of electrons through the sedimentary rock cycle, mediated largely by the weathering and burial of C‐S‐Fe phases. These processes buffer atmospheric pO₂.
