In Situ Amidation‐Derived Interfacial Modulation for Homogeneous Ultra‐High Nanoparticle Loading Toward Robust and Flexible Piezoelectric Composites

open access: yesAdvanced Functional Materials, EarlyView.
Synergistic interfacial strategy between inorganic ceramic fillers and polymer chains effectively inhibit particle aggregation and interfacial incompatibility. complex covalent and non‐covalent interfacial interactions promote superior uniformity, ultra‐high ceramic filler loading, and strong grain‐to‐grain connectivity, thereby enabling the ...

2D GRAVITY COUPLED TO TOPOLOGICAL MINIMAL MODELS [PDF]

open access: yesInternational Journal of Modern Physics A, 1995
We discuss the properties of genus 0 correlation functions of a topological minimal model (the model Ak+1) coupled to 2D topological gravity. The action of the twisted minimal model is perturbed by nontrivial couplings to gravitational descendants, which, in turn, are constructed entirely from the fields in the matter sector of the theory.

Hybrid quantum states in 2D dilaton gravity

open access: yesPhysical Review D, 2023
The classical black hole spacetime is modified semiclassically, depending strongly on the choice of the quantum states. In particular, for the Boulware state the spacetime often takes a wormhole structure mimicking closely a spacetime with a horizon.

Probing Hawking radiation through capacity of entanglement

open access: yesJournal of High Energy Physics, 2021
We consider the capacity of entanglement in models related with the gravitational phase transitions. The capacity is labeled by the replica parameter which plays a similar role to the inverse temperature in thermodynamics.

Shaping of Biohybrid Functional Living Materials

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates a strategy for shaping living mycelium into functional materials by directing its natural growth. Nanoparticles armor hyphae, micron‐scale particles entangle within the network, and printed hydrogel architectures steer expansion, creating defined geometries.

Quantum effects of the conformal anomaly in a 2D model of gravitational collapse

open access: yesJournal of High Energy Physics, 2023
The macroscopic effects of the quantum conformal anomaly are evaluated in a simplified two-dimensional model of gravitational collapse. The effective action and stress tensor of the anomaly can be expressed in a local quadratic form by the introduction ...

Thermo‐Mechanically Recyclable Smart Textiles from Circularly Knitted Liquid Crystal Elastomer Fibers

open access: yesAdvanced Functional Materials, EarlyView.
Reprogrammable multi‐material smart textiles knitted from liquid crystal elastomer fibers undergo 2D and 3D deformation under thermal and photo stimuli. Circularly knitted tubular structures reversibly contract in radial and axial directions, enabling autonomous climbing, liquid release, and micro pumping.

Stabilization of 2D Quantum Gravity by branching interactions [PDF]

open access: yes, 1995
In this paper the stabilization of 2D quantum Gravity by branching interactions is considered. The perturbative expansion and the first nonperturbative term of the stabilized model are the same than the unbounded matrix model which define pure Gravity ...

Covariant Effective Action and One-Loop Renormalization of 2D Dilaton Gravity with Fermionic Matter

open access: yes, 1993
Two dimensional dilaton gravity interacting with a four-fermion model and scalars is investigated, all the coefficients of the Lagrangian being arbitrary functions of the dilaton field.

Triblock Polymer Engineering Enables Hydration‐Rich, High‐Performance, Fouling‐Resistant Interfaces

open access: yesAdvanced Functional Materials, EarlyView.
A molecularly engineered triblock polymer (PHZ) rapidly reorganizes into a hydration‐rich interfacial layer on diverse surfaces, strongly suppressing hydrophobic attraction and fouling. The triblock polymer provides robust energy and steric barriers to oily foulants, enabling high‐performance antifouling at ultralow dosage.
