Data-driven analysis of hydrogen embrittlement in martensitic steels with interpretable machine learning

Materials & Design
A data-driven analytical framework integrating machine learning (ML), SHAP (SHapley Additive exPlanations) analysis, and symbolic regression (SR) was developed and applied to quantitatively analyze and interpret hydrogen embrittlement behavior in ...

Exploring Dipolar Dynamics and Ionic Transport in Metal‐Organic Frameworks: Experimental and Theoretical Insights

Advanced Functional Materials, EarlyView.
In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

Protection by Inhaled Hydrogen Therapy in a Rat Model of Acute Lung Injury can be Tracked \u3cem\u3ein vivo\u3c/em\u3e Using Molecular Imaging [PDF]

, 2017
Inhaled hydrogen gas (H2) provides protection in rat models of human acute lung injury (ALI). We previously reported that biomarker imaging can detect oxidative stress and endothelial cell death in vivo in a rat model of ALI.

Hydrogen diffusivity in aluminium

Philosophical Magazine Letters, 1988
Abstract The diffusivity and the migration energy of H in Al at high temperatures have been found to be consistent with low-temperature experiments when the possibility of temporary localization of the H atoms at thermal equilibrium vacancies is taken into account. The migration energy in the perfect lattice is determined to be 0·52±0·07eVand DH o ≈ 8 ×

Photoswitchable Conductive Metal–Organic Frameworks

Advanced Functional Materials, EarlyView.
A conductive material where the conductivity can be modulated remotely by irradiation with light is presented. It is based on films of conductive metal–organic framework type Cu3(HHTP)2 with embedded photochromic molecules such as azobenzene, diarylethene, spiropyran, and hexaarylbiimidazole in the pores.

Intermolecular Interactions as Driving Force of Increasing Multiphoton Absorption in a Perylene Diimide‐Based Coordination Polymer

Advanced Functional Materials, EarlyView.
This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.
