Deep learning approach for an interface structure analysis with a large statistical noise in neutron reflectometry

Scientific Reports, 2021
Neutron reflectometry (NR) allows us to probe into the structure of the surfaces and interfaces of various materials such as soft matters and magnetic thin films with a contrast mechanism dependent on isotopic and magnetic states.

Observation of a shape resonance of the positronium negative ion

Nature Communications, 2016
The Positronium negative ion is formed by two electrons bound to a positron, and experimental investigations of its states and energy levels are difficult due to its short lifetime.

Secondary ligand engineering of nanoclusters: Effects on molecular structures, supramolecular aggregates, and optical properties

Aggregate, 2023
Developing new templates to evaluate the ligand engineering effect in manipulating nanoclusters from both molecular and supramolecular aspects remains highly desired in cluster science because it allows for an in‐depth understanding of structure‐property

Sulfur Line Vacancies in MoS₂ for Catalytic Hydrogen Evolution Reaction

Crystals, 2022
Defects in transition metal dichalcogenides play important roles in the field of the catalytic hydrogen evolution reaction (HER). However, the use of defective MoS2 as HER catalysts remains controversial because the types of defects are various ...

J/ψ production within a jet in high-energy proton-proton and nucleus-nucleus collisions [PDF]

EPJ Web of Conferences
We report a systematic study of J/ψ production within a jet in pp and its modification in heavy-ion collisions. Within the framework of leading power factorization formalism of nonrelativistic QCD, we calculate the jet fragmentation function for high-pT ...

Electrically driven photon emission from individual atomic defects in monolayer WS2. [PDF]

, 2019
Quantum dot-like single-photon sources in transition metal dichalcogenides (TMDs) exhibit appealing quantum optical properties but lack a well-defined atomic structure and are subject to large spectral variability.
