OpenKV: LSM-tree-based key-value store for open-channel SSD
Log-structured merge (LSM) tree-based key-value stores, such as LevelDB and RocksDB, have seen great adoption in industry due to their high write speed. However, one major issue with LSM-based databases is the high write amplification. The root cause of this problem is the LSM tree structure that …

Production of single cell anode-supported SOFC using NiO/YSZ-YSZ-LSM/YSZ powder materials
… The materials for single cell are NiO/YSZ, YSZ, LSM/YSZ as anode, electrolyte and cathode, respectively. The cornstarch is used to create anode porosity while the material binder of the powder is polyvinyl alcohol (PVA) to increase green compact strength. The consolidation of anode was done using …
