Role of the Recombination Zone in Organic Light‐Emitting Devices

Advanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

Giant Anisotropic Spin Absorption in Chiral Hybrid Semiconductors

Advanced Materials, EarlyView.
Researchers uncover that chiral hybrid organic–inorganic semiconductors absorb spin differently depending on its polarization direction. This anisotropic spin absorption is primarily driven by the local symmetry breaking within the layered structure.

Best Proximity Pairs for Upper Semicontinuous Set-Valued Maps in Hyperconvex Metric Spaces

Fixed Point Theory and Applications, 2008
A best proximity pair for a set-valued map with respect to a map is defined, and new existence theorems of best proximity pairs for upper semicontinuous set-valued maps with respect to a homeomorphism are proved in hyperconvex metric spaces.

ON EXISTENCE OF OPTIMAL SOLUTIONS TO Ψ-RIEMANN LIOUVILLE FDE VIA BEST PROXIMITY RESULTS FOR GENERAL CONDENSING OPERATORS [PDF]

The paper utilizes the concept of measure of noncompactness to achieve the existence result; the existence of an optimal solution to a fractional system constituted by ψ-Riemann Liouville derivative and a nonlinear function of integral type.

Quantification of Magnetic Interactions in van der Waals Heterostructures Using Lorentz Transmission Electron Microscopy and Off‐Axis Electron Holography

Advanced Materials, EarlyView.
Cross‐sectional Lorentz TEM and off‐axis electron holography visualize the magnetic domain structure and quantify interlayer coupling in Fe3GeTe2/graphite/Fe3GeTe2 heterostructures. A stray‐field coupling length of 37±$\pm$7 nm marks the onset of domain misalignment between the layers.

Optimum solution of ( k , ℷ ) $(k,\gimel )$ -Hilfer FDEs by A $\mathcal{A}$ -condensing operators and the incorporated measure of noncompactness

Journal of Inequalities and Applications
The notion of A $\mathcal{A}$ -condensing operators via the measure of noncompactness is proposed, which retains the existing classes of condensing operators.

Best proximity point (pair) theorem using ( α − ς ) Meir-Keeler condensing operators in Busemann convex spaces

Applied General Topology
Two new class of condensing operators, called  ( α − ς ) and ( β − ς ) Meir-Keelercondensing operators, are introduced and used to investigate the existence of best proximity points (pairs) for cyclic (noncyclic) relatively nonexpansive mappings to more ...

Existence of generalized equilibrium pair in best proximity settings

Applied Mathematical Sciences, 2015
In this paper, using a general best proximity theorem, we will prove an existence theorem of equilibrium pair for a free n-person game, which generalizes the previous existence theorem of equilibrium pair for a free 1-person in [7].

Quantum Saturation of the Electro‐Optic Effect

Advanced Materials, EarlyView.
At low temperatures, quantum fluctuations saturate the ferroelectric soft mode, suppressing thermal sensitivity in functional properties. By tuning the phase boundaries of ferroelectric materials to 0 K, large temperature insensitive electro‐optic effects are realized, establishing a pathway toward high‐efficiency optical modulation for quantum ...
