Ion recombination correction in carbon ion beams
Ion recombination correction in carbon ion beamsPurpose: In this work, ion recombination is studied as a function of energy and depth in carbon ion beams. Methods: Measurements were performed in three different passively scattered carbon ion beams with energies of 62 MeV/n, 135 MeV/n, and 290 MeV/n using various types of plane-parallel ionization chambers. Experimental results were compared with two

Advanced Functional Materials, EarlyView.Sulfur‐doped graphitized carbon nanofibers act as adaptive catalyst–support platforms, enabling dynamic sulfur‐mediated reconstruction and strong metal–support interactions. This unique behavior enhances catalyst stability and controls reaction pathways, achieving highly selective urea oxidation (∼92% N2) coupled with efficient hydrogen evolution ...

Protons and Carbon Ions: The Japanese Carbon Ion Experience and Ideas for Further Investigation
Protons and Carbon Ions: The Japanese Carbon Ion Experience and Ideas for Further InvestigationRadiation oncology has never seen such rapid change before this decade, with a panoply of new technologies available. What kind of studies should be carried out to sort out their indications, advantages, and disadvantages? The paradigm of drug development in medical oncology from phase I to phase II to phase III trials remains unaltered, however it is ...

Bio‐Inspired Synthesis of Macroporous Single Crystal Particles as Scattering Agents
Advanced Functional Materials, EarlyView.A general strategy is presented that delivers unique, single‐crystal microparticles that combine submicron macroporosity and uniform particle shapes. A bioinspired approach is used to occlude three distinct types of additives – polystyrene microspheres, polymer vesicles and amino acids – within calcite single crystals, and subsequent thermal annealing ...

Nano‐Scale Characterization of Impurities Segregation in Solid Oxide Electrolysis Cells
Advanced Functional Materials, EarlyView.Cathodic polarization induces impurity segregation in Ni, forming an amorphous Na─Al─Si─O amorphous phase at grain boundaries. Under ultralow oxygen partial pressure, multiple elements dissolve, migrate, and reoxidize within the metal. A patterned model system provides direct nanoscale evidence, clarifying the mechanism of polarization‐driven impurity ...
