XTRUDE: A Process‐Informed Framework for High‐Fidelity Analysis of Hydrogel Extrusion

Advanced Functional Materials, EarlyView.
Extrusion performance emerges from the interplay between material properties and processing conditions. XTRUDE (eXTrusion Rheology for Understanding and Defining Extrudability) recreates the extrusion environment with in situ pressure and temperature sensing, enabling characteristic pressure signatures to quantify extrusion‐specific phenomena and ...

Effect of single straight, intersecting and T-shaped natural fractures on horizontal wellbore stability in shale reservoirs

Journal of Petroleum Exploration and Production Technology
The development of natural fractures can easily lead to horizontal wellbore instability caused by stress concentration after drilling in shale reservoirs, which is not conducive to the safe development of shale gas, but how different natural fractures ...

Investigation of the propagation behavior of hydraulic fractures and its influencing mechanisms in fractured reservoirs based on a hydromechanical coupling numerical model

Scientific Reports
Numerous discontinuities, such as bedding planes and natural fractures, occur in reservoir rocks and significantly influence the propagation behavior of hydraulic fractures during reservoir stimulation.

Mechanistic Origins of Chemo‐Mechanical Instability and Failure in Solid‐State Lithium‐Sulfur Electrodes

Advanced Functional Materials, EarlyView.
Conversion‐induced sulfur expansion generates strong mechanical constraints and localized stresses within solid‐state Li‐S cathodes. Heterogeneous solid‐electrolyte confinement creates tensile strain‐energy hotspots that govern particle cracking. Larger sulfur particles accelerate fracture, while higher porosity relaxes constraint and delays damage ...

Fractures of the Forearm

, 1981
We began functional bracing of fractures of the forearm after having gained experience with bracing of tibial and femoral fractures. It was initially suspected that braces similar to prostheses worn by amputees could successfully stabilize the fragments ...

Utilizing the Metastability of Spidroins as a Strategy for Improving Mechanical Properties of Biomimetic Spider Silk Fibers

Advanced Functional Materials, EarlyView.
Phase transitions are central for the assembly of recombinant silk proteins into fibers. Soluble protein can transition into condensed states such as condensates and gels. These states are metastable and evolve in a time‐dependent way. Metastability depends on the protein sequence, and this relationship can be used to enhance the mechanical properties ...

Study on the Influence of Network Characteristics of Artificial Main Fractures and Natural Fractures on the Effectiveness of Acid Fracturing

Carbonate reservoirs typically develop natural fractures, which significantly impact the effectiveness of acid fracturing processes. This study integrates the two-scale continuum model (TSC) and the embedded discrete fracture model (EDFM) to develop an ...
