Motif Editing for Reaction Pathway Switching From Formate to CO in Single‐Atom Indium Catalysts via Adjacent Carbon Site Manipulation

Advanced Functional Materials, Volume 36, Issue 62, 3 August 2026.
This work presents manipulation of adjacent carbon site in single‐atom indium catalysts via editing In‐N4 motif to In‐N2O2 for reaction pathway switching. Incorporation of O atoms leads to significant electron enrichment on the adjacent carbon sites surrounding the In‐N2O2 motif, which facilitates *COOH adsorption and CO formation with high selectivity.

Ni–Cr Substitution in TiFe: An Integrated Experimental–Modeling Study of Phase Stability and Hydride Thermodynamics

Advanced Energy and Sustainability Research, Volume 7, Issue 8, August 2026.
Combined experimental and theoretical approaches reveal how Cr and Ni substitution in TiFe‐based alloys tune lattice expansion and hydride thermodynamics. While both elements increase hydride stability, they exert opposite effects on the entropy of hydrogen desorption, providing new insight into thermodynamic design of AB‐type hydrogen storage ...

Tuning the Magnetic Phase Transitions in TbMn2‐xTixSi2 (x = 0–0.3)

Advanced Physics Research, Volume 5, Issue 8, August 2026.
ABSTRACT Magnetocaloric materials receive considerable attention as promising candidates for next‐generation energy‐efficient and environmentally benign solid‐state refrigeration technologies. These materials exhibit the magnetocaloric effect (MCE), whereby heat is absorbed or released upon the application or removal of a magnetic field. In this study,

Quantum Phenomena in Molecular and Biological Systems: A Decoherence‐Based Decision Framework With Falsifiable Predictions and a Failure‐Mode Taxonomy

Advanced Physics Research, Volume 5, Issue 8, August 2026.
A physics‐grounded framework based on decoherence timescales (τ_dec vs τ_func), Markovian validity, and falsifiability criteria is applied across molecular systems to distinguish where quantum effects are necessary, marginal, or irrelevant. The analysis integrates quantum chemistry, biological quantum mechanisms, and quantum computing under a unified ...

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic

Communications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1973-2102, August 2026.
ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

Transient Response Analysis of Quasi‐Synchronization and Self‐Synchronization Grid‐Connection Processes for Nuclear Power (N + X) Emergency Diesel Generator Units

Engineering Reports, Volume 8, Issue 8, August 2026.
The upper portion condenses the five‐unit EDG arrangement into repeated diesel–governor and generator–AVR modules, distinguishing four operating units from one standby unit. Measured data and the equipment configuration jointly support a calibrated full‐system model, which then feeds two parallel research tracks covering self‐synchronization and quasi ...

On Kotzig's Perfect Set Problem of Hamiltonian Cycle Decompositions of the Complete Graph

Journal of Combinatorial Designs, Volume 34, Issue 8, Page 388-409, August 2026.
ABSTRACT A Hamiltonian cycle decomposition (HCD) of K n is a set of Hamiltonian cycles in which each 1‐path of K n appears exactly once. A Dudeney set of K n is a set of Hamiltonian cycles in which each 2‐path of K n appears exactly once. Kotzig's perfect set of HCDs of K n is a set of HCDs whose union forms a Dudeney set.

Tight Bounds for Hypercube Minor‐Universality

Journal of Graph Theory, Volume 112, Issue 4, Page 433-437, August 2026.
ABSTRACT A graph G is m‐minor‐universal if every graph H with at most m edges and no isolated vertices is contained as a minor in G. Recently, Benjamini, Kalifa and Tzalik proved that there is an absolute constant c > 0 such that the d‐dimensional hypercube Q d is ( c ⋅ 2 d / d)‐minor‐universal, while there is an absolute constant K > 0 such that Q d ...
