Redox dual‐defects (Cs substitution and O vacancies) in 2D hydrated WO3 steer O2 activation toward selective singlet oxygen evolution. WO‐CO achieves 8.6–15.8 times higher 1O2 production than single‐defect or pristine catalysts, enabling efficient pollutant mineralization via a pathway‐selective photocatalytic mechanism.

Lower-modular elements of the lattice of semigroup varieties [PDF]
We call a semigroup variety modular [upper-modular, lower-modular, neutral ] if it is a modular [respectively upper-modular, lower-modular, neutral] element of the lattice of all semigroup varieties.

Review of Thermally Activated Twisted Coiled Polymer Actuators: A Materials Science Perspective
Thermally activated twisted and coiled polymer actuators (TCPAs) combine lightweight design, large deformation, and scalable fabrication for soft robotic and wearable applications. This review connects polymer structure, processing history, helix geometry, and thermomechanical characterization to actuator performance, highlighting current challenges in

Special Elements in the Lattice of Overcommutative Semigroup Varieties Revisited [PDF]
We completely determine all distributive, codistributive, standard, costandard, and neutral elements in the lattice of overcommutative semigroup varieties, thus correcting a gap in a previous paper. © 2010 Springer Science+Business Media B.V.The work was

DEFINABILITY OF THE VARIETY GENERATED BY A COMMUTATIVE MONOID IN THE LATTICE OF COMMUTATIVE SEMIGROUP VARIETIES [PDF]
. Let M be a commutative monoid. We construct a first-order formula that defines the variety generated by M in the lattice of all commutative semigroup varieties.

Diagnostic analysis via the heterojunction validation funnel. The funnel illustrates the hierarchical stratification of 30 reported Type‐II systems based on the three‐phase, seven‐step diagnostic framework. Complete validation through all phases is achieved by only 3.3% of systems, while 96.7% lack full mechanistic validation, revealing a pervasive ...

On universality of semigroup varieties [PDF]
summary:A category $K$ is called $\alpha $-determined if every set of non-isomorphic $K$-objects such that their endomorphism monoids are isomorphic has a cardinality less than $\alpha $.

CuFeS2 is found to induce the formation of intermediate phases, highlighting a strong Cu–Fe synergistic effect during conversion reactions in lithium all‐solid‐state batteries (Li‐SSBs). The integrated reaction pathway effectively suppresses phase separation and accelerates reaction kinetics, leading to enhanced electrochemical reversibility and ...

Submicron Metasurface Reconfigured Multiband Smart Windows
This work presents a submicron metasurface reconfigured multiband thermochromic smart window. By integrating subwavelength nanostructures into a Fabry−Perot resonator configuration, it mitigates conventional trade‐offs to simultaneously deliver high luminous transmittance and robust solar heating and radiative cooling modulation capabilities ...

Shaping Matter with Acoustic Waves: From Particles to Functional Structures
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward
