Using Recycled Materials in a Novel Dual Binder System for Hard Carbon Anodes: Closing the Loop Toward Sustainable Li‐/Na‐ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The study explores for the first time the use of polyvinyl butyral (PVB), particularly recycled PVB, as a sustainable binder for Li/Na‐based electrodes in the framework of the H2020 SUNRISE EU project. Findings revealed that electrodes bound with a sustainable PAA/PVB mixture demonstrated exceptional rate capability and high initial Coulombic ...

State dependence of Krylov complexity in 2d CFTs

open access: yesJournal of High Energy Physics, 2023
We compute the Krylov Complexity of a light operator O $$ \mathcal{O} $$ L in an eigenstate of a 2d CFT at large central charge c. The eigenstate corresponds to a primary operator O $$ \mathcal{O} $$ H under the state-operator correspondence.

Fibered Correspondence [PDF]

open access: yesarXiv, 2007
Base of fibered correspondence is arbitrary correspondence. Fibered correspondence is interesting when we consider relationship between different bundles. However composition of fibered correspondences may not always be defined. Reduced fibered correspondence is defined only between fibers over the same point of base.

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Omnidirectional Transmissive Acoustic Metasurfaces Based on Goldberg Polyhedra

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces omnidirectional acoustic metasurfaces capable of manipulating wavefronts in multiple arbitrary directions simultaneously. A full‐stack pipeline for design, optimization, and fabrication is presented to construct near‐spherical holograms based on Goldberg polyhedra.

Native Lignin Migration and Clustering in Wood: Superhydrophobic, Antimold, and Tribonegative Layers for Rain‐Driven Electrification

open access: yesAdvanced Functional Materials, EarlyView.
This study proposes a sustainable solution for rainwater‐driven energy harvesting by harnessing the intrinsic properties of lignin in wood. The first demonstration of an all‐wood tribonegative material for liquid–solid triboelectric nanogenerators is presented, eliminating the need for fluorine‐containing polymers and functional additives. Abstract The

Holographic meson decays via worldsheet instantons

open access: yesJournal of High Energy Physics, 2018
We study meson decays using instanton methods in two string models. The first model is the old string model in flat space which combines strings and massive particles and the second is the holographic, Sakai-Sugimoto model. Using the old string model, we

The Twistor correspondence of the Dolbeault complex over $\C^n$ [PDF]

open access: yesarXiv, 1995
With respect to the Dolbeault complex over the flat manifold $\C^n$, an explicit description of the inverse correspondence of the twistor correspondence is given.

Fluoride‐Free Molten Salt Hydrate‐Assisted Synthesis of MXene in Air Down to 150 °C

open access: yesAdvanced Functional Materials, EarlyView.
A novel low‐temperature shielded salt (LSS) approach enables the synthesis of MXenes in air at temperatures as low as 150 °C using MgCl2·6H2O/LiCl. This method demonstrates successful etching of challenging MXenes like Cr2CTx and Nb2CTx through the synergistic effects of Li+ ions and salt hydrate phase changes, while eliminating the need for inert ...

Learning the Alpha-bits of black holes

open access: yesJournal of High Energy Physics, 2019
When the bulk geometry in AdS/CFT contains a black hole, boundary subregions may be sufficient to reconstruct certain bulk operators if and only if the black hole microstate is known, an example of state dependence.
