Guiding and Manipulating Light Fields in Microstructured Liquid Crystals

Advanced Physics Research, EarlyView.
This review summarizes recent advances in guided‐wave optics enabled by microstructured liquid crystal (LC) devices, covering their fundamental material properties, key degree of freedom for dynamic light field manipulations. The advances of linear guided‐wave optics, nonlinear‐optics with spatial optical solitons, and microlasers in LC‐based devices ...

Sintering‐Driven Modulation of Lattice Dynamics, Elastic Behavior, and Dielectric Response in Al–Sn Co‐Doped Zinc Ferrite Nanoparticles

Advanced Physics Research, EarlyView.
Sintering ZnAl0.1Sn0.1Fe1.8O4 nanoparticles at 1200°C optimizes structural lattice dynamics, significantly enhancing both macroscopic elastic stiffness and high‐frequency dielectric response through synergistic Al3+ stabilization and Sn4+‐driven charge transport. ABSTRACT In this work, ZnAl0.1Sn0.1Fe1.8O4 (ZASFO) ferrites were synthesized via a sol–gel

Developing a critical caste analysis within information science and technology: A research review: An annual review of information science and technology paper

Journal of the Association for Information Science and Technology, EarlyView.
Abstract Caste—an ascriptive social hierarchy in South Asia and its diaspora—is a globalized phenomenon. Recent caste‐based discrimination, particularly in technology companies and anti‐caste efforts to address it, has compelled academia, policy, and the technology industry to better understand contemporary mechanics of caste.

Infinite Functional Versatility, Formidable Limits: Evaluating Gallium‐Based Liquid Metals in Rechargeable Batteries

Carbon Energy, EarlyView.
Beyond the hype surrounding the self‐healing properties of gallium‐based liquid metals (Ga‐LMs), this perspective critically examines their functional roles in metal‐ion batteries, highlighting both their underlying merits and the often‐overlooked challenges, including non‐representative design and testing configurations, performance overestimations ...

Single‐Step Synthesis of Dithieno[3,2‐b:2′,3′‐e]Pyridines and Their Acid‐Dependent Optical and Photosensitising Properties

Chemistry – A European Journal, EarlyView.
The synthesis of dithieno[3,2‐b:2′,3′‐e]pyridines (DTPs) is herein reported, and their optical properties are studied both experimentally and computationally. Protonation or methylation of the nitrogen atom induced bathochromic shifts in their absorption and emission spectra.

Asymmetric Diphosphane Dioxides With A–π–A–π’–D Scaffolds for High‐Purity Deep‐Blue Luminescence

Chemistry – A European Journal, EarlyView.
Diphosphane dioxide‐based luminophores with donor–π–acceptor– π’–acceptor scaffold enable efficient deep‐blue emission from tunable charge‐transfer states affording high photoluminescence up to 95%. OLEDs reach EQE 4.9%, aided by triplet–triplet annihilation, highlighting a practical route to high‐performance blue emitters.

Front Propagation Through a Perforated Wall

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We consider a bistable reaction– diffusion equation ut=Δu+f(u)$u_t=\Delta u +f(u)$ on RN${\mathbb {R}}^N$ in the presence of an obstacle K$K$, which is a wall of infinite span with many holes. More precisely, K$K$ is a closed subset of RN${\mathbb {R}}^N$ with smooth boundary such that its projection onto the x1$x_1$‐axis is bounded and that ...
