▪ Abstract Metal-hydrogen (M-H) systems are interesting from both a theoretical and practical point of view. M-H utilized for energy-storage systems, in sensor applications, catalysis. These often exploited as models studying basic material properties, especially when the size these is small nonbulk-like contributions become dominant. Surfaces, nanocrystals, vacancy- dislocation-rich materials, thin films, multilayers, clusters major interest addressed this review. We show that hydrogen...
Hydrogen interactions with imperfections in crystalline metals and semiconductors are reviewed. Emphasis is given to mechanistic experiments theoretical advances contributing predictive understanding. Important directions for future research discussed.
Grain refinement through severe plastic deformation enables synthesis of ultrahigh-strength nanostructured materials. Two challenges exist in that context: First, deformation-driven grain is limited by dynamic dislocation recovery and crystal coarsening due to capillary driving forces; second, boundary sliding hence softening occur when the size approaches several nanometers. Here, both have been overcome drawing a pearlitic steel wire (pearlite: lamellar structure alternating iron carbide...
Abstract Current greenhouse gas emissions suggest that keeping global temperature increase below 1.5 degrees, as espoused in the Paris Agreements will be challenging, and to do so, achievement of carbon neutrality is utmost importance. It also clear no single solution can meet neutral challenge, so it essential for scientific research cover a broad range technologies initiatives which enable realization free energy system. This study details broad, yet targeted themes being pioneered within...
Hydrogen concentration-pressure isotherms of surfactant-stabilized palladium clusters and polymer-embedded with diameters 2, 3, 5 nm are measured the gas sorption method at room temperature. The results show that, compared to bulk palladium, hydrogen solubility in \ensuremath{\alpha} phase is enhanced fivefold tenfold, miscibility gap narrowed. Both can be explained by assuming that occupies subsurface sites clusters. Pd-H all existence hysteresis, even though formation misfit dislocations...
