Bolapolyphiles With Bulky Carbosilane‐Based Lateral Groups—Reticular Design of Liquid Crystalline Pentagonal Honeycombs

open access: yesChemistry – A European Journal, EarlyView.
T‐shaped bolapolyphiles with highly branched carbosilane‐based side‐groups self‐assemble into liquid crystalline honeycombs composed of type‐2 pentagonal prismatic cells and p2gg plane group symmetry. ABSTRACT Periodic pentagon tessellations are rarely observed in self‐assembled molecular systems.

Modular Assembly of a Biocatalytic Material for Stereoselective C─Si Bond Formation

open access: yesChemistry – A European Journal, EarlyView.
A modular, carrier‐free enzyme foam derived from Rhodothermus marinus cytochrome c combines structural stability with catalytic efficiency for stereoselective C─Si bond formation. Streptavidin (STV)‐mediated protein crosslinking creates a robust, self‐supporting materials platform for next‐generation biocatalysis.

New Insights Into the Three‐Dimensional Mechanics of the Flagellar Beat Cycle

open access: yesCytoskeleton, EarlyView.
ABSTRACT Advances in imaging at the molecular scale have provided greater detail concerning the three‐dimensional structure of the ciliary/flagellar axoneme. Additionally, it has recently been confirmed that electrostatic forces regulate the dynein‐tubulin interaction at the microtubule binding domain (MTBD) of dynein, and at the junction of the nexin ...

Real‐time lithology identification while drilling based on drill cuttings image analysis with ensemble learning

open access: yesDeep Underground Science and Engineering, EarlyView.
A lithology identification while drilling method was developed, integrating an automated cuttings sampling system, a smart drilling rig, and an ensemble learning model. Underground trials achieved 97.42% accuracy in real‐time identification of cuttings lithology and composition, enhancing hazard management and supporting unmanned drilling technology in

Multi‐factor coupling effects in hydraulic fracturing of laminated shale: Experimental insights and physics‐informed neural network‐driven optimization

open access: yesDeep Underground Science and Engineering, EarlyView.
This study establishes a multi‐factor coupling framework for predicting breakdown pressure in laminated shale by integrating experimental hydraulic fracturing tests, physics‐informed neural networks (PINNs), and Sobol sensitivity analysis. It reveals how differential stress, the bedding dip angle, and the injection rate interact to influence fracture ...
