Flexible photocatalytic materials: From substrate engineering to multi‐field synergistic enhancement

open access: yesFlexMat, EarlyView.
This review examines flexible photocatalytic systems, covering substrate evolution from polymers to biomass, fabrication methods like electrospinning, and key mechanical and optoelectrochemical metrics under deformation. Enhancement strategies are critically discussed, followed by applications in energy conversion, environmental remediation, and ...

Diffeomorphism invariant tensor networks for 3d gravity

open access: yesJournal of High Energy Physics
Tensor networks prepare states which share many features of states in quantum gravity. However, standard constructions are not diffeomorphism invariant and do not support an algebra of non-commuting area operators.

Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

open access: yesGeological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

THE GEOMETRY OF THE STANDARD MODEL: Deriving the Higgs Mass, Lagrangians, and Gravity Echoes from Lattice Saturation

open access: yes
The Standard Model describes what particles do, but not why they exist. Parameters like the Higgs Mass (125 GeV) are manual inputs. The Selection-Stitch Model (SSM) derives these parameters from geometry. By modeling the vacuum as a K= 12 Cuboctahedral Lattice, we derive the fundamental Lagrangians (Dirac, Yang-Mills) as the elastic limits of the ...

Toward Low‐Power Laser Refrigeration ‐ Cooling a Resonant WGM Crystalline Cavity

open access: yesLaser &Photonics Reviews, EarlyView.
Laser refrigeration offers a method to cool solids to low temperatures by using only light. By illuminating bulk crystals doped with rare‐earth ions one can engineer the emitted fluorescent light to be at shorter wavelengths than the pump light ‐ thus extracting heat/phonons from the solid and cooling the crystals.

Emergent dark matter and dark energy from a lattice model

open access: yesEuropean Physical Journal C: Particles and Fields
We propose a quantum bosonic qubit model on a fcc lattice that realizes the canonical source structure of mimetic dark matter as a defect of a rank-two lattice Gauss law.

Experimental Study on Polymer–Polymer Interfacial Thermal Resistance

open access: yesMacromolecular Theory and Simulations, Volume 34, Issue 2, March 2025.
Interfacial thermal resistance (ITR) in polymer–polymer interfaces is experimentally measured in this paper by the multi‐layered bulk sample approach. Based on numerical simulation and experimental verification, new techniques of layer‐overlapping samples are developed.

An Elasto–Plastic Hydro–Mechanical Model for Analyzing the Swelling Behavior of Heterogeneous Clay–Sulfate Rocks

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Swelling of clay‐sulfate rocks is a concern in geotechnical engineering that can damage infrastructure. In the historic town of Staufen in southwest Germany, geothermal drilling into a swellable anhydrite‐bearing clay formation resulted in water inflow and subsequent swelling, triggering ground heave and damage to more than 250 houses.

Modified Whittle estimation of multilateral models on a lattice. [PDF]

open access: yes
In the estimation of parametric models for stationary spatial or spatio-temporal data on a d-dimensional lattice, for d≥2, the achievement of asymptotic efficiency under Gaussianity, and asymptotic normality more generally, with standard convergence rate,

Discrete Lorentzian quantum gravity [PDF]

open access: yes, 2000
Just as for non-abelian gauge theories at strong coupling, discrete lattice methods are a natural tool in the study of non-perturbative quantum gravity.
