On the wake of a Darrieus turbine [PDF]

, 1981
The theory and experimental measurements on the aerodynamic decay of a wake from high performance vertical axis wind turbine are discussed. In the initial experimental study, the wake downstream of a model Darrieus rotor, 28 cm diameter and a height of ...

Single‐Atom Photocatalyst as Floatable Artificial Leaf for Upcycling Oceanic Plastic Waste

Advanced Materials, EarlyView.
To resolve the catastrophic disaster of oceanic plastic pollution, the novel Ru single atom loaded ZnIn2S4 photocatalysts, in the forms of powder or floatable artificial leaf, were prepared for direct conversion of raw polypropylene plastic into valuable chemicals. The optimized catalyst exhibits exceptional performance, with a total formic/acetic acid

Wake flowfields for Jovian probe [PDF]

The wake flow field developed by the Galileo probe as it enters the Jovian atmosphere was modeled. The wake produced by the probe is highly energetic, yielding both convective and radiative heat inputs to the base of the probe.

Study of a Novel Bi‐Layered Thermoplastic Polyurethane Patch for Congenital Diaphragmatic Hernia

Advanced Materials Interfaces, EarlyView.
Large congenital diaphragmatic hernia remains a challenge due to the poor compatibility of current prostheses. To tackle this problem, a bilayer thermoplastic polyurethane patch with tunable mechanical properties is engineered, whose fibrous side supports rapid fibroblast and myoblast colonization, while the smooth film limits adhesions.
