Interface Rectification via Roll‐to‐Roll Dual‐Confinement Nanocoatings for High‐Temperature Polymer Capacitors

Advanced Science, EarlyView.
Dual confinement in self‐assembled nanocoatings regulates polymer dynamics and hot‐carrier transport, enabling an interface‐rectification strategy for high‐temperature polymer capacitive energy storage. ABSTRACT Polymer film capacitors are indispensable for energy storage and power conversion, yet their energy density and efficiency deteriorate rapidly

Discrete JT gravity as an Ising model

Journal of High Energy Physics
Inspired by the program of discrete holography, we show that Jackiw-Teitelboim (JT) gravity on a hyperbolic tiling of Euclidean AdS2 gives rise to an Ising model on the dual lattice, subject to a topological constraint.

Habitat‐Specific Design Strategies for Untethered Soft Robots

Advanced Science, EarlyView.
Habitat shapes the design of untethered soft robots. Across land, water, air, and living tissues, environmental constraints govern viable combinations of compliant structures, actuation mechanisms, and energy delivery. This review connects these constraints with robotic performance and identifies design principles for advancing adaptable, durable, and ...

Zr Incorporation Into Lithium Nickel Oxides: Bulk or Surface Substitution?

Advanced Science, EarlyView.
Mechanism of Zr incorporation into lithium nickel oxide (LNO) cathodes is studied from atomistic to macroscale. Zr doping enhances cyclability of Li‐ion batteries with LNO via bulk, interface, and grain boundary optimization leading to structural integrity at atomistic‐ and micro‐scale of secondary particle aggregates.

Gravity Equation and Trade Agreements: A Different Econometric Approach [PDF]

This paper is aimed at multiplicatively estimating the parameters of the gravity equation by using the Poisson Pseudo-Maximum-Likelihood (PPML) estimator, and taking heteroskedasticity into account at the same time.

Evolution of Physical Intelligence Across Scales

Advanced Intelligent Discovery, EarlyView.
By following the evolution of physical intelligence across scales, this article shows how intelligence arises from materials, structures, physical interactions, and collectives. It establishes physical intelligence as the evolutionary foundation upon which embodied intelligence is built.

Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

Lethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

ESTIMATION ISSUES IN SINGLE COMMODITY GRAVITY TRADE MODELS [PDF]

Recently gravity trade models are applied to disaggregated trade data. Here many zeros are characteristic. In the presence of excess zeros usual Poisson Pseudo Maximum Likelihood (PPML) is still consistent, the variance covariance matrix however is ...

Smart holes: analogue black holes with the right temperature and entropy

Journal of High Energy Physics
In analogue gravity studies, the goal is to replicate black hole phenomena, such as Hawking radiation, within controlled laboratory settings. In the realm of condensed matter systems, this may happen in 2D tilted Dirac cone materials based on honeycomb ...
