Advanced Materials, EarlyView.High‐entropy materials (HEMs), typically composed of five or more principal elements in near‐equimolar ratios, offer significant potential due to their unique properties. This review outlines the emergence and structural evolution of HEMs, followed by an in‐depth discussion of the elemental roles (active sites, promoters, or stabilizers) for water ...

Quantum gravity kinematics from extended TQFTs
New Journal of Physics, 2017 In this paper, we show how extended topological quantum field theories (TQFTs) can be used to obtain a kinematical setup for quantum gravity, i.e. a kinematical Hilbert space together with a representation of the observable algebra including operators of

Breaking the Selectivity Barrier of Single‐Atom Nanozymes Through Out‐of‐Plane Ligand Coordination
Advanced Materials, EarlyView.Here, Ru SAzyme with out‐of‐plane chlorine ligands is reported as a monofunctional, high‐performance peroxidase‐like nanozyme. Incorporating out‐of‐plane ligand coordination emulates enzyme selectivity and regulates reaction pathways for an identical substrate.

Local gauge theory and coarse graining
, 2012 Within the discrete gauge theory which is the basis of spin foam models, the problem of macroscopically faithful coarse graining is studied. Macroscopic data is identified; it contains the holonomy evaluation along a discrete set of loops and the ...

Biomimetic Cell Membrane‐Coated Scaffolds for Enhanced Tissue Regeneration
Advanced Materials, EarlyView.This review examines the development and use of cell membrane‐coated scaffolds in tissue engineering. Bioinspired phospholipid and glycocalyx coatings enhance anti‐fouling, anti‐thrombogenic, and selective molecular recognition properties. Native cell membrane coatings further support cell‐specific interactions, immune modulation, and reduced bacterial

Quantum Gravity as a Broken Symmetry Phase of a BF Theory
Symmetry, Integrability and Geometry: Methods and Applications, 2006 We explain how General Relativity with a cosmological constant arises as a broken symmetry phase of a BF theory. In particular we show how to treat de Sitter and anti-de Sitter cases simultaneously.

N=2 supersymmetric spin foams in three dimensions
, 2007 We construct the spin foam model for N=2 supergravity in three dimensions. Classically, it is a BF theory with gauge algebra osp(2|2). This algebra has representations which are not completely reducible.

Biopolymer Membranes for Osmotic Power Generation in Bionic Applications
Advanced Materials, EarlyView.This review provides an overview of biopolymer‐based osmotic power generation for bionic applications. It uniquely bridges biopolymer membranes, reverse electrodialysis(RED), and bionic applications, addressing a critical research gap by integrating biopolymer membranes with RED technologies for biomedical use.

Ce Single Atom‐Engineered Amorphous/Crystalline Nanosheets for Enhanced Alkaline Water Electrolysis
Advanced Materials, EarlyView.We leveraged Ce single‐atom engineering to generate short‐range ordered crystalline nanodomains in amorphous RuOx for creating amorphous/crystalline nanojunctions, in an effort to regulate the water dissociation kinetics for enhanced HER. Specifically, the Ce‐doped crystalline nanodomains greatly reduce the energy barrier to water dissociation and ...
