A New Customizable Surfactant LLPS Strategy for Sustainable and Highly Efficient Radioactive Metal Ion Separation

open access: yesAdvanced Science, EarlyView.
A diluent‐free, customizable liquid–liquid phase separation (LLPS) platform enables highly efficient radioactive metal ion extraction and stripping. By encapsulating hydrophobic extractants into an ionic surfactant‐rich condensed phase, this LLPS system leverages synergistic electrostatic and coordination interactions.

Sticky Yet Slippery: Molecular Ordering Reconciles Bubble‐Surface Affinity With Ultralow Friction at the Nanoscale

open access: yesAdvanced Science, EarlyView.
By engineering the molecular order and thickness of PDMS layers, we reconcile the stickiness and slipperiness during bubble transport. AFM measurements and MD simulations further reveal how these nanoscale architectures tune hydrophobic interaction FHB and friction force f.

Shear‐Induced Emergence of Aromatic Superlow‐Friction Interfaces in Amorphous Carbon: Triggering Chemical Impurities and Atomic‐Scale Mechanisms

open access: yesAdvanced Science, EarlyView.
High‐throughput quantum‐mechanical simulations reveal that amorphous carbon undergoes shear‐driven structural transformation into aromatic, graphene‐like interfaces. This mechanochemical process is governed by dopant chemistry: dopants with valency less than four promote the emergence of superlow‐friction amorphous graphene, whereas tetra‐valent ...

Observation of Excitonic Instability in a Monolayer Ta2NiSe5 With Strain Disorder

open access: yesAdvanced Science, EarlyView.
Monolayer Ta2${\rm Ta}_2$NiSe5${\rm NiSe}_5$ sustains an excitonic insulating phase up to 190 K, with Raman signatures of gap opening and critical excitonic fluctuations. Thickness‐independent large gap ratios highlight strong exciton‐phonon coupling, while substrate‐induced strain disorder depresses Tc, establishing monolayer Ta2${\rm Ta}_2$NiSe5${\rm

Instability of shock waves in a van der Waals gas

open access: yesInstability of shock waves in a van der Waals gas
航空宇宙技術研究所 6-7 JUN. 1996 東京 日本 National Aerospace Laboratory 6-7 JUN. 1996 Tokyo Japan ファンデルワールス気体中の衝撃波の不安定性あるいは安定性を数値的に検討した。まず、いくつかの型の衝撃遷移が存在する可能性を明らかにした。次いで、これらの衝撃の時間発展を数値的に求めた。その結果、超音速-亜音速衝撃だけが安定して存在出来ることが分かった。しかし、全ての超音速-亜音速衝撃が必ずしも安定ではなく、超音速-亜音速条件は衝撃が安定しているための必要条件の一つに過ぎない。衝撃分離過程、あるいは不安定衝撃遷移の時間発展についてもシミュレーションを行った。 Instability or stability of shock ...
