Rare Mononuclear Lithium-Carbene Complex for Atomic Layer Deposition of Lithium Containing Thin Films. [PDF]

Angew Chem Int Ed Engl
A new N‐heterocyclic carbene (NHC) stabilized lithium complex is introduced as a thermally stable atomic layer deposition (ALD) precursor. It features a rare mononuclear structure, suitable volatility, and a low melting point of 55 °C. ALD trials yielded lithium silicate films.

Study on the flow and heat transfer characteristics of Li4SiO4 pebble bed based on DEM-CFD coupling

International Journal of Advanced Nuclear Reactor Design and Technology
The blanket is a key component for producing tritium in fusion reactors. To ensure the blanket operates effectively and safely, it is crucial to maintain efficient heat transfer in the pebble bed. Furthermore, the breeder material needs to operate within

Enhancing properties of Li2TiO3/Li4SiO4 tritium breeding ceramics by chitosan addition

Nuclear Materials and Energy, 2023
Li2TiO3/Li4SiO4 ceramics have been regarded as promising tritium breeders due to their numerous merits. In this work, chitosan was employed as an effective binder to provide adhesion of Li2TiO3 particles to Li4SiO4 particles, resulting in Li2TiO3/Li4SiO4

Annihilation kinetics of irradiation defects in promising tritium breeding pebbles

Nuclear Materials and Energy, 2021
Lithium-based tritium breeding materials will be adopted to produce tritium in the D-T fusion reactor. Li2TiO3 and Li4SiO4 pebbles have been proposed as candidates in water-cooled ceramic breeder blanket (WCCB) and helium-cooled ceramic breeder blanket ...

Acidity-Mediated Metal Oxide Heterointerfaces: Roles of Substrates and Surface Modification. [PDF]

Adv Mater
The role of local space charge, not only at heterointerfaces, but also at grain boundaries, influenced by surface acidity modulation is elucidated through model platforms composed of Pr‐doped ceria (mixed ionic‐electronic conducting oxide) nanowire arrays.

Characterization of Aged Li4sio4 Pebbles Performance

Fusion Engineering and Design, 2023
Many studies and research have been carried out in the recent years to identify which breeder material and (in which) form, solid or liquid, are most suitable to be used in the Breeder Blanket (BB) modules. Nonetheless, the choice of a stable material, with high thermal conductivity and melting point remains unsolved and becomes even more complex when ...

Li4SiO4-based Adsorbents for CO2 Capture at High Temperature: Performance Enhancement by Ball-milling Process

Chemical Engineering Transactions, 2023
Post-combustion capture technologies based on regenerable solid sorbents are attracting increasing attention as ways to reduce CO2 emissions. The present study focused on the fabrication at industrial lab-scale of lithium orthosilicate (Li4SiO4) sorbents

Preliminary investigation of Li4SiO4 pebbles structural performance

Fusion Engineering and Design, 2021
Abstract One of the main purposes of a breeder blanket is to remove the heat produced in the blanket by the fusion reaction neutrons, and to breed the tritium required to sustain it. To achieve these requirements, several breeder materials (solid or liquid lithium-bearing ones) have been investigated in the past decades.

Lithium orthosilicate as nuclear fusion breeder material: Optimization of the drip casting production technology

Nuclear Materials and Energy, 2022
The production of nuclear fusion energy, in the future DEMOnstration power plant (DEMO), is based on tritium self-sufficiency, achievable exploiting neutron-lithium reaction occurring in the breeding blanket modules. To fulfil the plant design conditions
