Electrolyte Design for Fast‐Charging Lithium‐Based Batteries

Advanced Materials, EarlyView.
A decade of progress in fast‐charging electrolytes for lithium batteries is reviewed. Electrolyte design strategies spanning solvents, salts, additives, and advanced systems, such as localized high‐concentration electrolytes (LHCEs), are summarized. Advanced diagnostic tools for lithium plating and interphase chemistry are discussed, with perspectives ...

Effect of Magnetic Field on Electric and Acoustic Properties of the PDMS Ferromagnetic Gel

Archives of Acoustics, 2008
A polymer gel (ferrogel) is an assembly of ferromagnetic nanoparticles embeded in gel. In the ferrogel, the finely distributed magnetic particles are suspended in the swelling liquid and forma flexible matrix due to adhesive forces.

Wearable Morphology‐Adaptive in‐Ear Device With Active Cleansing Capability for Multimodal Health Monitoring

Advanced Materials, EarlyView.
We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.

Acoustic Features of Filled Pauses in Polish Task-Oriented Dialogues

Archives of Acoustics, 2013
Filled pauses (FPs) have proved to be more than valuable cues to speech production processes and important units in discourse analysis. Some aspects of their form and occurrence patterns have been shown to be speaker- and language-specific.

“It’s a Bit Tricky, Isn’t It?”—An Acoustic Study of Contextual Variation in /ɪ/ in the Conversational Speech of Young People from Perth

Languages
This study presents an acoustic analysis of vowel realisations in contexts where, in Australian English, a historical contrast between unstressed /ɪ/ and /ə/ has largely diminished in favour of a central schwa-like variant.
