All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

Advanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Tuning the Dielectric Properties of Individual Clay Nanosheets by Interlayer Composition: Toward Nano‐Electret Materials

Advanced Functional Materials, EarlyView.
The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of

Thermal Energy Storage, Heat Pump and Thermal Energy Transportation Technologies. Cold Heat Storage Performance of Amine/Water Solutions.

KAGAKU KOGAKU RONBUNSHU, 1998
主に液化天然ガス冷熱の蓄冷を目的として, -20～-50℃で有効な新たな蓄冷媒体の探索を行った.2成分水溶液系について検討を行い, アミン系水溶液に可能性を見出した.固液平衡測定実験から, この溶液群は2段階の凝固過程を持つ共晶性を示した.最も低い温度での蓄冷性能が期待されたメチルアミン水溶液について相変化観察試験を行った.メチルアミン水溶液は第1段階の凝固にて樹枝状デンドライト結晶を形成し流動性の高いスラリー性状を示した.実験結果を基に流動性を伴った潜熱型高密度蓄冷媒体として, この共晶性溶液の可能性を検討した.
