Elucidating the Interplay Between Structure and Electrochemical Behavior in Lignin‐Based Polymer Electrolytes for Potassium Batteries

open access: yesBattery Energy, Volume 4, Issue 2, March 2025.
Three biobased membranes are synthesized by crosslinking oxidized Kraft lignin with poly(ethylene glycol) diglycidyl ether of increasing molecular weights. After incorporation of solvated potassium salts, potassium batteries including these biobased gel polymer electrolytes are able to deliver a maximum specific capacity at 0.05 A g−1 as high as 130 ...

Nitrogen‐Stitched rGO/Graphite Bilayer Anodes for Accelerated Li‐Ion Transport and Interfacial Charge Regulation

open access: yesCarbon Energy, EarlyView.
Nitrogen‐stitched rGO forms an active charge‐regulating bilayer on graphite that pre‐adsorbs, guides, and delivers Li+ into the lattice. This adsorption–migration–diffusion pathway accelerates Li+ transport, stabilizes the interface, and enables fast‐charging performance beyond conventional graphite limits.

Seismic Response Analysis of Continuous Girder Bridges Crossing Faults with Assembled Rocking-Self-Centering Piers

open access: yesBuildings
Under the action of cross-fault ground motion, bridge piers can experience significant residual displacements, which can irreversibly impact the integrity and reliability of the bridge structure.

Deciphering Polarity Effects of Polymer to Regulate Li+ Ionic Environment in Solid Polymer Electrolytes for Solid‐State Lithium Batteries

open access: yesCarbon Energy, EarlyView.
We elucidate the fundamental influences of polymer polarity on Li+ ionic environments in solid polymer electrolytes by considering four critical components: Li+, FSI−, residual solvents, and polymer matrix. Beyond facilitating LiFSI dissociation and Li+ transport, our findings underscore previously overlooked roles of polymer polarity, thereby ...

Statistical valuation of vibrations at the rock drilling

open access: yesActa Montanistica Slovaca, 2006
The paper describes a measuring device providing a monitoring of forced vibrations arising at the rock cutting by impregnated diamond drilling tools at quasi-constant revolutions and thrust levels. The forced vibrations were measured by a capacity acceleration transducer.

In‐situ asphaltene capture with iron oxide nanoparticles in steam‐assisted gravity drainage (SAGD) for improved recovery and partial upgrading of bitumen

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Key improvements obtained by incorporating nanoparticles into a lab‐scale SAGD process configuration. The bar plots show enhanced oil recovery, reduced viscosity, and increased asphaltene adsorption in nanoparticle‐assisted scenarios compared with conventional SAGD.

An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system

open access: yesDeep Underground Science and Engineering, EarlyView.
The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an

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

Exploring wave propagation behaviors in rock: A grain‐based perspective on mineral structures

open access: yesDeep Underground Science and Engineering, EarlyView.
This study investigates wave propagation in rock at the grain scale using a grain‐based model, revealing that mineral elastic modulus significantly influences wave attenuation while grain size and distribution have limited effects. A novel peak particle velocity attenuation prediction model is proposed and validated for grain‐scale wave propagation ...
