Cobalt‐Free Single‐Crystal Cathodes for Next‐Generation Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cobalt‐free single‐crystal cathodes enhance lithium‐ion battery stability by mitigating fracture, degradation, and phase transitions. This review highlights Ni‐rich layered, Li‐Mn‐rich, spinel, and olivine frameworks, synthesis strategies enabling morphology and defect control, and structural tuning via doping and coatings, offering pathways toward ...

A comprehensive analysis of the (R13xR13)R13.9{\deg} type II structure of silicene on Ag(111)

, 2016
In this paper, using the same geometrical approach than for the (2R3x2R3) R30{\deg} structure (H. Jamgotchian et al., 2015, Journal of Physics. Condensed Matter 27 395002), for the (R13xR13)R13.9{\deg} type II structure, we propose an atomic model of the

Wide‐Field Autostereoscopic 3D Display Enabled by Isolated Microlens Array and Gradual Radius Lens Design

Journal of the Society for Information Display, EarlyView.
This paper proposes an Isolated Microlens Array (I‐MLA) with Gradual Radius Lens (GRL) design for a wide‐field autostereoscopic floating 3D display in compact form. Extended coding pitch and directional mesh eliminate crosstalk, while radially varying microlens curvature maintains sharp images at large angles. Simulations show a practical continuous 40°

Robustness of Planar Fourier Capture Arrays to Colour Changes and Lost Pixels

, 2012
Planar Fourier capture arrays (PFCAs) are optical sensors built entirely in standard microchip manufacturing flows. PFCAs are composed of ensembles of angle sensitive pixels (ASPs) that each report a single coefficient of the Fourier transform of the far-

Deep Optical Cryptography: Joint Encryption and LC Lens Key Generation for Secure Displays

Journal of the Society for Information Display, EarlyView.
We propose a learning‐based visual cryptography system using a liquid crystal modulator for distance‐dependent optical decryption. By jointly optimizing ciphertext images and LC‐based optical keys with shift‐aware training, the framework ensures secure plaintext recovery only at designated distances.

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

Laser &Photonics Reviews, EarlyView.
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

Robust flat bands in twisted trilayer graphene moiré quasicrystals

Nature Communications
Moiré structures formed by twisting three layers of graphene with two independent twist angles present an ideal platform for studying correlated quantum phenomena, as an infinite set of angle pairs is predicted to exhibit flat bands.

Multifunktionale DNA‐Moiré‐Supergitter: Moiré‐Strukturen aus den Bausteinen des Lebens

Physik in unserer Zeit, EarlyView.
Moiré‐Strukturen sind längst ein Schlüsselbegriff in der modernen Festkörperphysik. Sie entstehen, wenn sich zwei periodische Materialgitter mit leicht unterschiedlichen Gitterkonstanten oder Orientierungen übereinanderlagern. Das so entstehende großflächige Interferenzmuster, das als Moiré‐Muster bezeichnet wird, kann die physikalischen Eigenschaften ...
