Abstract Nonvolatile control of electron spin using electric polarization offers a promising route toward energy-efficient spintronic devices. Early studies of conventional ferroelectrics, from GeTe to perovskite oxides, demonstrated that polarization switching can reversibly control spin textures…
Abstract On-chip optoelectronics underpins modern telecommunications, yet its integration density is fundamentally bottlenecked by the diffraction limit of light. Hyperbolic polaritons─hybrid light-matter excitations in materials with opposite-signed dielectric permittivity tensor components─emerge…
The persistent shortage of donor organs and the inherent drawbacks of autologous grafts highlight the urgent need for advanced biomaterial scaffolds in regenerative medicine. Synthetic polymers and animal-derived matrices offer structural support, yet they frequently lack the biological complexity…
ABSTRACT Helicenes are attractive emitters of circularly polarized light, yet strategies to enhance their luminescence dissymmetry factor ( g lum ) remain underdeveloped. Herein, we report a scalable, facile synthetic route to hetero[9]helicenes utilizing a benzofuran scaffolding strategy. This eff…
Abstract Polymers are remarkable macromolecules that can be fabricated with ease for the required potential applications, including biotechnology, medicine, engineering, and nanotechnology. Biocompatible and biodegradable polymers are now widely adopted in pharmaceutical formulations, since they of…
Although Ethiopia’s road network has expanded significantly in recent years, maintaining long-term pavement performance remains a major challenge. In response to increasing sustainability concerns, modern road construction practices emphasize the recycling and reuse of existing asphalt materials, a…
ABSTRACT The vicious cycle of “oxidative stress‐ferroptosis‐inflammatory response” is a key cause of the progression of myocardial ischemia‐reperfusion injury (MIRI), but single antioxidant or anti‐inflammatory therapies have not yielded satisfactory therapeutic effects. In this study, we developed…
The ambient-pressure superconducting transition temperature of nickelate thin films has progressed from 45 K in (La,Pr)₃Ni₂O₇ epitaxial films (Nature 2025) to above 60 K in pure bilayer structures (team reports, 2026). The next application-critical quantities are the critical current density Jc and…

The bottom-up assembly of colloidal quantum dots (CQDs) into superlattice structures is attractive for leveraging nanocrystal quantum features into films and optoelectronic devices. However, current CQD superlattices often require tedious control of the assembly kinetics, and they suffer from eithe…
Conspectus The development of host molecules has long been central to the progress of supramolecular chemistry and the design of advanced functional materials. Over the past several decades, a wide variety of host architectures─including crown ethers, cyclodextrins, cucurbiturils, calixarenes, cali…
The increasing demand for broadband and self-powered optoelectronic devices has stimulated the development of two-dimensional (2D) material-based photodetectors. Here, we construct a self-powered photodetector based on a MoSe2/SnS2 van der Waals (vdW) heterostructure. The unique combination of MoSe…
FINDING: IMO 2011 Q2 "windmill" problem reveals invariant parity structure in finite point configurations under rotating lines. | MATH: For \(n\) points in general position, a rotating line through a point \(p\) sweeps through all points; the parity of the number of points on each side of the line…
In this theoretical study, we employ first-principles density functional theory calculations using the generalized gradient approximation to systematically investigate the structural, electronic, and thermodynamic properties of alkali–ammonium compounds XNH 4 (X = Li, Na, K) intended for solid-stat…
We introduce Nonlinear GENERIC-Embedded Neural Networks (N-GENNs), a deep learning framework for discovering evolution equations of systems governed by the nonlinear GENERIC formalism (General Equation for Non-Equilibrium Reversible–Irreversible Coupling). Such systems exhibit coupled conservative…

Abstract In this study, a slurry-coating procedure was successfully employed to deposit a Cu0.2Zn0.8S film on glass substrates. X-ray diffraction (XRD) and Raman spectroscopy analyses confirmed the formation of a polycrystalline, phase-pure cubic structure. Scanning electron microscopy (SEM) reveal…
