Flexible Unusual Ternary‐Component Graded‐Modulus Dielectric Films with High‐Density Capacitive Energy Storage

open access: yesAdvanced Science, EarlyView.
Hierarchical PP–LSR107–BaTiO3 nanocomposite films are fabricated by one‐step extrusion and stretching for roll‐to‐roll manufacture, combining high energy storage and processing flexibility. LSR107 surrounds BaTiO3‐rich regions, locating amorphous PP, decreasing defects, and introducing deep traps that homogenize the electric field and suppress charge ...

Scalable Engineering of Bio‐Manufactured Extracellular Vesicles for Selective Delivery in Ovarian Cancer Patient‐Derived Models

open access: yesAdvanced Science, EarlyView.
Engineered extracellular vesicles displaying Ephrin‐B2 selectively target Ephrin‐B4–expressing ovarian cancer cells, enabling precise delivery in patient‐derived models. This scalable bio‐manufacturing platform reveals a versatile strategy to exploit Ephrin signaling for highly specific therapeutic payload delivery and motivates exploration of tailored

Arrangements of Submanifolds and the Tangent Bundle Complement

open access: yes, 2011
. Drawing parallels with hyperplane arrangements, we develop the theory of ar-rangements of submanifolds. Given a smooth, finite dimensional, real manifold X we consider a finite collection A of locally flat, codimension-1 submanifolds that intersect ...

Electrostatic Self‐Assembly Induced Nest‐Like MXene Networks on Fabric for Ultra‐Broadband Flexible Absorption

open access: yesAdvanced Science, EarlyView.
In this study, an electrostatically self‐assembled WPU‐MXene@FC flexible fabric constructs a “nest‐like” structure on fibers, building construct MXene multiple loss paths, achieving ultra‐wideband absorption of 25.3–1200 GHz in a thickness of 1.8 mm, while also exhibiting superhydrophobicity, acid and alkali resistance, and bending resistance ...

A Recursive Scheme of First Integrals of the Geodesic Flow of a Finsler Manifold

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2007
We review properties of so-called special conformal Killing tensors on a Riemannian manifold $(Q,g)$ and the way they give rise to a Poisson-Nijenhuis structure on the tangent bundle $TQ$.

Tailoring Successive Magnetic‐Dielectric Synergy for Enhancing Electromagnetic Absorption in Ultralong Heterostructure Chains Assisted by High Static Magnetic Field

open access: yesAdvanced Science, EarlyView.
This work proposes a high static magnetic field (HSMF) driven dual‐low‐dimension strategy for fabricating magnetic‐dielectric heterostructure (Fe3O4@MoS2) chains with programmable lengths. The constructed successive magnetic‐dielectric synergy, arising from uniaxial anisotropy‐enhanced magnetic response and abundant heterointerfaces that boost ...

Ultra‐Low Intensity Continuous Wave Laser Ablation Propulsion With Graphene‐Engineered Wood

open access: yesAdvanced Science, EarlyView.
Graphene delignified wood converts continuous wave laser energy into thrust. Laser propulsion experiments in vacuum reveal the lowest laser ablation threshold intensities and the greatest density‐normalized specific impulse in literature. The results highlight graphene delignified wood as a potential efficient, sustainable, strong, and lightweight ...

Self‐Assembly Ordered Layered Gels for Thermochromic Smart Windows With Excellent Electromagnetic Shielding Properties

open access: yesAdvanced Science, EarlyView.
Metal‐ion‐coupled self‐assembled layered gels were prepared using a simple sol–gel method, successfully integrating electromagnetic shielding and thermochromic functions into the material. SCa‐1, which exhibits the best overall performance, achieves an electromagnetic shielding efficiency of up to 72.49 dB, while maintaining a visible light ...
