Spatial‐Compatibility‐Assisted Molecular Intercalation in MXenes

Advanced Materials, EarlyView.
This work demonstrates a solvent–free NH4F–mediated route for simultaneous Al removal and molecular intercalation in MXenes. Intercalants are selected by comparing their crystallographic X, Y, and Z dimensions with the MXene interlayer spacing, establishing a spatial‐compatibility criterion that rationalizes guest–host matching and enables predictive ...

Inductively Expandable Supraparticles as Microscopic Force Generators for Remote Mechanical Actuation

Advanced Materials, EarlyView.
This study demonstrates the combination of magnetic nanoparticles and functional blowing agents into supraparticles. Upon induction heating, they actuate via rapid gas generation or extensive volume expansion. These supraparticles lift up to 25 000 times their own mass and rapidly open cured epoxy resins, providing a versatile strategy for fast micron ...

The Challenge of Measuring Airflow Through Mine Regulators to Allow Real Time Ventilation Monitoring

, 2002
The mathematical modeling of airflow through operating mine regulators is discussed. Results are used in the development of a computerized monitoring and simulation system to provide immediate or real time data on air behavior within each branch within ...

Theoretical knowledge enhanced genetic algorithm for mine ventilation system optimization considering main fan adjustment

Complex & Intelligent Systems
Mining safety heavily depends on ventilation, which constitutes a significant portion of the energy costs in operations. Optimizing mine ventilation systems (MVSO) is crucial for minimizing this energy expenditure.

On the Ventilation of Coal Mines [PDF]

Proceedings of the Yorkshire Geological Society
I shall make no apology for the introduction of this subject before the Geological and Polytechnic Society, as it is certain that the person who would discover any safer modes of ventilation, or even any additional precautions to those now in use, and should succeed in having them generally adopted, would be for ever conferring a lasting benefit upon ...

BAP31 Drives Cartilage Calcification through Disruption of Autophagosome–Lysosome Fusion in Osteoarthritis

Advanced Science, EarlyView.
Mechanical stress activates BAP31 in chondrocytes. BAP31 competes with ATG14 for binding to STX17, disrupting the STX17–ATG14 complex required for autophagosome–lysosome fusion. The resultant autophagic flux blockade drives the generation of autophagy‐derived exosomes, which mediate pathological cartilage calcification in OA. Chondrocyte‐targeted BAP31

Optimizing Mine Ventilation Systems: An Advanced Mixed-Integer Linear Programming Model

Mathematics
In the underground mine ventilation area, the absence of robust solutions for nonlinear programming models has impeded progress for decades. To overcome the enduring difficulty of solving nonlinear optimization models for mine ventilation optimization, a

Pre‐Regenerative Endothelial Cells Empowered by Antler Blood Exosomes Orchestrate Peripheral Nerve Repair

Advanced Science, EarlyView.
The pre‐regenerative vascular niche (PVN) is essential for nerve repair, yet its endothelial blueprint remains unclear. We identified angiogenic ECs (AECs) as the dominant pre‐regenerative subset and found that antler blood–derived exosomes (AB‐EXO) promote repair via IMP3.
