Copper Doping Enhances the Activity and Selectivity of Atomically Precise Ag44 Nanoclusters for Photocatalytic CO2 Reduction

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
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 ...

Integrated Experimental and Theoretical Insights into Defect‐Induced Functionalities of Cobalt Doped NiO for Multifunctional Solar‐Driven Applications

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
Rational defect engineering in Co‐doped NiO nanostructures, synthesized via a sustainable green route, enables precise bandgap modulation and defect‐state tailoring. Combined experimental–density functional theory analysis identifies 15% Co doping as the optimal threshold for maximizing photocatalytic degradation, photothermal response, and hydrogen ...

Evaluating Feynman integrals by the hypergeometry

Nuclear Physics B, 2018
The hypergeometric function method naturally provides the analytic expressions of scalar integrals from concerned Feynman diagrams in some connected regions of independent kinematic variables, also presents the systems of homogeneous linear partial ...

Theoretical Understanding of Mechanical and Thermal Performance of Mo2Ti‐Based Nitride and Carbonitride MXenes

Annalen der Physik, Volume 538, Issue 3, March 2026.
Our density functional theory results reveal that ligand‐mediated bonding and charge redistribution fundamentally govern the electronic, mechanical, and thermal behavior of double transition metal MXenes, providing a unified and mechanistic understanding of their structure–property relationships.

The Feyn-structure of Yangian symmetry

Journal of High Energy Physics
Yangian-type differential operators are shown to constrain Feynman integrals beyond the restriction to integrable graphs. In particular, we prove that all position-space Feynman diagrams at tree level feature a Yangian level-one momentum symmetry as long

Two-Loop Vertices in Quantum Field Theory: Infrared and Collinear Divergent Configurations

, 2006
A comprehensive study is performed of two-loop Feynman diagrams with three external legs which, due to the exchange of massless gauge-bosons, give raise to infrared and collinear divergencies.

Hawking radiation from Feynman diagrams [PDF]

Physical Review D, 1999
The aim of this letter is to clarify the relationships between Hawking radiation and the scattering of light by matter falling into a black hole. To this end we analyze the S-matrix elements of a model composed of a massive infalling particle (described by a quantized field) and the radiation field.

Feynman's Diagrams, Pictorial Representations and Styles of Scientific Thinking [PDF]

, 2017
In this paper we argue that the different positions taken by Dyson and Feynman on Feynman diagrams’ representational role depend on different styles of scientific thinking.

α‐Al2O3 Networks on MLG Membranes for Continuous Lithium Ion Extraction from Artificial Sea Water with Enhanced Selectivity and Durability

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 2, March 2026.
An α‐Al2O3‐decorated multilayer graphene membrane enables highly selective lithium ion extraction from artificial seawater via electrodialysis. The confined ion channels and competitive ion transport dynamics enhance lithium selectivity, achieving 88.9% purity and 88.6% recovery over three extraction cycles while maintaining stable ion flux.
