Strain and Band Modulation of WO3/SnSe Micro‐Nano Composites Achieving Superior Photocatalytic Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
WO3/SnSe micro‐nano composites demonstrate exceptional photocatalytic performance through synergistic strain and band modulation. Lattice strain modulation enhances methyl orange adsorption and visible light absorption, while Z‐scheme band alignment promotes efficient charge separation. The 2.5% WO3/SnSe composite achieves 99.71% degradation efficiency,

Weak‐Story Mitigation and Drift Redistribution in Moment‐Resisting Frames Using Stepping Rocking Walls

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This study investigates the seismic response of moment‐resisting frames retrofitted with a stepping rocking wall, with emphasis on weak‐story mitigation and residual drift reduction under both ordinary and pulse‐like ground motions. Nonlinear response‐history analyses are conducted on 9‐story and 20‐story SAC Los Angeles frames.

Iron Energy Carrier: Experimental Characterisation, Combustion Diagnostic and Benchmarking with Other Clean Metal Fuels

open access: yesEnergy Science &Engineering, EarlyView.
This study investigates how iron particles burn across a wide size range, revealing late‐stage nanoparticle release and a previously unrecognised shift in combustion behaviour near 118 µm. High‐speed imaging, PMT diagnostics and SEM analyses have been conducted.

Exact Computation of the Color Function for Triangular Element Interfaces

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
We propose a robust algorithm, the Front2VOF algorithm, to compute the color function for triangular element interfaces in Front‐Tracking methods on a Cartesian mesh. ABSTRACT The calculation of the volume enclosed by curved surfaces discretized into triangular elements and a cube is of great importance in different domains, such as computer graphics ...

Investigation of Some Conditions on N (k)-Quasi Einstein Manifolds [PDF]

open access: yes, 2011
. We consider N (k)-quasi Einstein manifolds satisfying the conditions R(ξ, X) · H = 0, H(ξ, X) · S = 0, P (ξ, X) · H = 0, R(ξ, X) ·P = 0 and P (ξ, X)·S = 0 where H, P andP denote the conharmonic curvature tensor, the projective curvature tensor and ...

Perfect fluid spacetimes with harmonic generalized curvature tensor [PDF]

open access: yes, 2019
We show that n-dimensional perfect fluid spacetimes with divergence-free conformal curva- ture tensor and constant scalar curvature are generalized Robertson Walker (GRW) spacetimes; as a consequence a perfect fluid Yang pure space is a GRW spacetime. We

Kuga–Satake Construction on Families of K3 Surfaces of Picard Rank 14

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT The isometry between the type IV6 and the type II4 hermitian symmetric domains suggests a possible relation between suitable moduli spaces of K3 surfaces of Picard rank 14 and of polarized abelian 8‐folds with totally definite quaternion multiplication. We show how this isometry induces a geometrically meaningful map between such moduli spaces

Anisotropic Initial Damage and Its Effect on Tensile Response of Plain Concrete

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Damage is often described as isotropic, implying that a scalar value describes its initial state. However, the prior micro‐cracking pattern at points of an existing building, that is, the initial damage, may be oriented by a preload. The degradation of the Volume Element due to oriented preloads shall be described as anisotropic and ...

Overshooting of Hypoplastic Models With Intergranular Strain: Manifestation, Implications and Remedy

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Intergranular strain extensions of hypoplasticity (IGS, ISA, GIS) are widely used to model small‐strain and cyclic soil behaviour. However, recent studies and our own simulations reveal that these models can exhibit stress overshooting not only under repeated small loading cycles but also during monotonic loading.
