Circularly Polarized Electroluminescence and Spin‐Polarized Carrier Transport in Chiral‐Doped Polymer Films

Advanced Functional Materials, EarlyView.
Chiral dopants induce supramolecular chirality in an achiral polymer (PFO), generating spin‐polarized carriers via the chiral‐induced spin selectivity (CISS) and suggesting a possible contribution of Spin‐polarized carrier transport to circularly polarized electroluminescence (CPEL).

Amphoteric Cu‐Doping Leading to High Thermoelectric Performance in p‐Type Bismuth Antimony Telluride

Advanced Functional Materials, EarlyView.
This study shows that Cu plays two opposite roles in p‐type Bi0.5Sb1.5Te3 depending on the processing route. Under thermodynamic‐equilibrium bulk‐synthesis, Cu mainly occupies cation sites, increases hole concentration, preserves mobility, and slightly reduces lattice heat transport. The best‐performing composition among the investigated series reaches

Electrocatalytic response of electrodes modified with metal phthalocyanines in the cholinesterase-thiocholine ester system [PDF]

, 2002
Hydrolysis products in the cholinesterase-thiocholine ester system were determined by voltammetry using electrodes modified with metal phthalocyanines (MPc, M = Fe, Co). Specific features of the electrooxidation of the hydrolysis product (thiocholine) at

Sacrificial‐Layer‐Assisted Heat‐Affected‐Zone Suppression in Laser Patterning of PET for High‐Performance Flexible Devices

Advanced Functional Materials, EarlyView.
A removable sacrificial polymer layer engineers the thermal boundary condition during nanosecond laser ablation of PET, suppressing heat‐affected‐zone formation without relying on costly ultrafast lasers. This strategy enables deep, high‐aspect‐ratio trenches with no detectable heat‐affected zone, templating silver‐filled mesh electrodes with record ...

Al3+/Ta5+ Co‐Doping Promotes Homogeneous Li+ Transport Enabling High Performance Ni‐Rich Layered Oxide Cathodes

Advanced Functional Materials, EarlyView.
Al3+/Ta5+ co‐doping refines the primary particles of LiNiO2, reduces Li/Ni antisite disorder, and expands the c‐axis lattice parameter, thereby enabling faster and more homogeneous Li+ transport. Such rapid and homogeneous Li+ transport suppresses high‐voltage phase transitions and microcrack formation, ultimately improving the rate capability and long‐

Chemically modified electrodes applyes to electroanalysis: a brief presentation

, 2015
Chemically modified electrodes (CMEs) have been subject of considerable attention since its inception about 23 years ago. CMEs result of a deliberate immobilization of a modifier agent onto the electrode surface obtained through chemical reactions ...

Nitride MXenes Beyond Carbides: Bridging the Gap Between Computational Prediction and Experimental Realization

Advanced Functional Materials, EarlyView.
Nitride MXenes remain constrained by a persistent gap between computational prediction and experimental realization. This Review identifies the thermodynamic, kinetic, and chemical barriers limiting their synthesis, critically evaluates emerging fabrication routes, and proposes a multidimensional computational‐experimental framework to accelerate the ...
