Pixelation‐Free, Monolithic Iontronic Pressure Sensors Enabling Large‐Area Simultaneous Pressure and Position Recognition via Machine Learning

open access: yesAdvanced Functional Materials, EarlyView.
A pixelation‐free, monolithic iontronic pressure sensor enables simultaneous pressure and position sensing over large areas. AC‐driven ion release generates spatially varying impedance pathways depending on the pressure. Machine learning algorithms effectively decouple overlapping pressure–position signals from the multichannel outputs, achieving high ...

Thermally Activated Delayed Fluorescence in Phase‐Separated Nanostructures

open access: yesAdvanced Functional Materials, EarlyView.
A supramolecular, phase‐separation driven strategy yields charge transfer (CT) complexes from alternating electron‐deficient pyromellitic diimide and electron‐rich 4,5‐dibromoveratrole. The resulting CT complexes self‐assemble into lamellar nanosheets with nanometer‐sized domains that exhibit thermally activated delayed fluorescence (TADF) at room ...

Timbre differences of an individual voice in solo and in choral singing

open access: yesArchives of Acoustics, 2015
The object of the study was to analyze differences between solo and choral production of the same singer. Six female and six male chorus singers sang the same musical material solo, in vocal groups, and as a choir.

s‐Orbital Mediated Metavalent Bonding Enables State‐Of‐The‐Art n‐Type AgBiSe2 Thermoelectrics

open access: yesAdvanced Functional Materials, EarlyView.
Metavalent bonding (MVB) underpins the exceptional property portfolio of chalcogenides. Typical MVB solids are mainly found in p‐bonded systems. This work reveals that MVB can also be formed with s‐p orbital interactions upon forming a single‐electron σ‐bond, as exemplified in AgBiSe2.

Ultrasound‐Triggered Gelation for Restoring Biomechanical Properties of Degenerated Functional Spinal Units

open access: yesAdvanced Healthcare Materials, EarlyView.
This study introduces an innovative approach to treating intervertebral disc degeneration using ultrasound‐triggered in situ hydrogel formation. Proof‐of‐concept experiments using optimized biomaterial and ultrasound parameters demonstrate partial restoration of biomechanical function and successful integration into degenerated disc tissue, offering a ...

Simplified prediction models for acoustic installation effects of train-mounted equipment

open access: yesRailway Engineering Science
Acoustic models of railway vehicles in standstill and pass-by conditions can be used as part of a virtual certification process for new trains. For each piece of auxiliary equipment, the sound power measured on a test bench is combined with measured or ...
