Advanced Functional Materials, EarlyView.By a simple anti‐Galvanic reaction, up to six copper atoms could be preferably doped into the Ag2(SR)5 staple motifs and Ag20 dodecahedral shell of an atomically precise Ag44(SR)30 nanocluster. When anatase TiO2 is used as substrate, the (AgCu)44/TiO2 photocatalyst exhibited much improved activity in photocatalytic CO2 reduction compared to Ag44/TiO2 ...

Magnetically Guided Mechanoactive Mineralization Scaffolds for Enhanced Bone Regeneration
Advanced Functional Materials, EarlyView.A 3D‐printed ‘rebar‐concrete’ inspired scaffold (PGS‐P@MGel) synergizes spontaneous biomineralization with magneto‐mechanical stimulation through PDA@Fe3O4‐embedded hydrogel. This dual biointerface activates Piezo1/β‐catenin/YAP mechanotransduction axis, enhancing BMSCs osteogenesis and angiogenesis simultaneously.

Automata theory for XML researchers [PDF]
ACM SIGMOD Record, 2002 The advent of XML initiated a symbiosis between document research, databases and formal languages (see, e.g., the survey by Vianu [38]). This symbiosis resulted, for instance, in the development of unranked tree automata [3]. In brief, unranked trees are finite labeled trees where nodes can have an arbitrary number of children.

Substrate Engineering for Durable Omniphobic Liquid‐Like Surfaces
Advanced Functional Materials, EarlyView.The significant yet less investigated role of substrates in determining the liquid‐repellency and mechanical durability of liquid‐like surfaces (LLSs) is explored. Thick and crack‐free sol–gel silica intermediary layers are developed that can smoothen substrate asperity roughness even at the micron scale, enabling omniphobic polydimethylsiloxane‐based ...

Conformally Perforated Shellular Metamaterials with Tunable Thermomechanical and Acoustic Properties
Advanced Functional Materials, EarlyView.This study introduces Conformally Perforated Shellular Metamaterials (CPSMs), which overcome TPMS design limitations by mapping 2D cellular layouts onto 3D surfaces. CPSMs exhibit enhanced elastic stiffness, thermal conductivity, and acoustic performance compared to intact P‐type shellulars, demonstrating their potential as multifunctional ...

Chemo‐Mechanical Coupling in Hydrogels: Dynamics in the Diffusion‐Limited Regime
Advanced Functional Materials, EarlyView.A time‐dependent continuum model is developed to capture the transient swelling dynamics of chemo‐mechanical hydrogels. By coupling chemical reactions, solvent transport, and polymer deformation, volume phase transitions, reaction kinetics, and transient mechanical instabilities are analyzed.

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

The automata theory of semigroup embeddings [PDF]
Journal of the Australian Mathematical Society, 1968 AbstractThe theorem of Trevor Evans [1] that every countable semigroup can be embedded in a two-generator semigroup becomes obvious in automata theory as the statement that every countable automaton can be embedded in one with binary inputs. Standard techniques of automata theory [1], [3] yield a proof of the Evans Theorem using wreath products, as in ...
