A coupled fully kinetic hydrogen transport and ductile phase-field fracture framework for modeling hydrogen embrittlement

This paper presents a novel coupled fully kinetic hydrogen transport and ductile phase-field fracture framework that successfully models hydrogen embrittlement by capturing the critical role of dislocation segregation and the competition between loading rates and diffusion kinetics, thereby reproducing experimental observations of crack initiation shifts, multiple surface cracking, and the transition from ductile tearing to brittle fracture.

A Physics-Informed Chemical Rule for Topological Materials Discovery

This paper introduces a physics-informed, interpretable linear framework that integrates compositional, orbital, and crystallographic descriptors to rapidly and accurately identify topological materials, overcoming the limitations of composition-only heuristics by distinguishing polymorphs and enabling high-throughput discovery where conventional symmetry indicators fail.

The effect of Nb and O on the martensitic transformation in the Ti-Nb-O alloys

This study reveals that while niobium primarily governs the evolution and symmetry of α"\alpha" martensite in Ti-Nb-O alloys by stabilizing the β\beta phase, oxygen distinctly modifies transformation pathways by suppressing ω\omega phase formation at lower niobium levels but inhibiting long-range martensitic transformation at higher levels due to local lattice distortions.

Near 13% efficient semitransparent Cu(In,Ga)S2 solar cells with band gap of 1.6 eV on transparent back contact

This study demonstrates that wide-gap (1.6 eV) semitransparent Cu(In,Ga)S₂ solar cells with In₂O₃:Sn transparent back contacts can achieve efficiencies near 13% by optimizing sodium supply and high-temperature growth, while balancing GaOₓ interfacial layer thickness to prevent current blocking.

Loss analysis of Low Bandgap (Ag,Cu)(In,Ga)Se2 Solar Cells for Tandem Applications

This study analyzes 18.5% efficient 1.0 eV (Ag,Cu)(In,Ga)Se2 solar cells for tandem applications, identifying that while current losses stem from absorption, the most significant performance limitations arise from non-radiative recombination affecting open-circuit voltage and a high diode factor indicating strong space charge region recombination.

Additive-Induced Stabilization of the Energetic Landscape of PM6:Y12 Organic Solar Cells

This study demonstrates that incorporating the solvent additive 1-chloronaphthalene (1-CN) significantly enhances the photostability of PM6:Y12 organic solar cells by stabilizing the donor's HOMO energy level and preserving nanostructural integrity, thereby preventing the driving force loss and efficiency degradation observed in additive-free devices.

ALD Zinc Tin Oxide Buffers for Chalcopyrite Solar Cells: Electrical Barriers and Conduction Band Cliffs

This study demonstrates that the tin content in atomic layer deposition-grown ZnSnO buffer layers for chalcopyrite solar cells directly correlates with the conduction band minimum, where low tin induces detrimental conduction band cliffs that lower open-circuit voltage, while high tin creates electron transport barriers that reduce fill factor and short-circuit current.
