The instability of a viscous sheet floating on an air cushion [PDF]

, 2004
The dynamics of a thin sheet of viscous liquid levitating on an air cushion is studied. Experimentally, it is observed that, after an initial settling stage, a local disturbance grows, eventually leading to the sheet blowing up like a viscous balloon ...

Leidenfrost‐Assisted Synthesis of Indium‐Substituted Mixed Phosphate Cathodes with Superior Cycling Stability and Enhanced Sodium Storage Kinetics

Small, EarlyView.
The work presents a Leidenfrost‐assisted synthesis as a low‐cost and scalable approach for designing In3+‐doped mixed phosphate ([PO4]3−‐[P2O7]4−) cathodes. The optimized cathode composition exhibits exceptional electrochemical performance, with a specific capacity of 129.3 mAh g−1 at 0.05 C, corresponding to an energy density of ∼$\sim $359 Wh kg−1 ...

In Vitro Hemocompatibility of the BiVACOR Total Artificial Heart in Continuous and Pulsatile Flow

Artificial Organs, EarlyView.
BiVACOR's total artificial heart generates remarkably similar hemocompatibility when operated with a pulse or during continuous flow. Under both conditions, hemolysis and von Willebrand Factor multimers were similar to a commercial reference device after 6 h in vitro evaluation.

Shock metamorphic effects in Itokawa phosphates: A comparison with megaregolith‐derived meteorites

Meteoritics &Planetary Science, EarlyView.
Abstract Returned regolith samples from the asteroid Itokawa provide a unique opportunity to compare shock metamorphic effects in unconsolidated regolith materials with those preserved in lithified meteorites, that is, megaregolith. We analyzed four Itokawa particles (Ueda—RA‐QD02‐0519, Narahara—RA‐QD02‐0573, Domon—RA‐QD02‐0588, Ishiuchi—RX‐MD03‐0212 ...
