The three-dimensional leading-edge vortex of a "hovering' model hawkmoth [PDF]

, 1997
Recent flow visualization experiments with the hawkmoth, Manduca sexta, revealed a small but clear leading-edge vortex and a pronounced three-dimensional flow.

Thresholds and influencing factors on vortex bursting of an ogive-cylinder body-delta wing: an experimental and numerical approach

Advances in Aerodynamics
Despite the exceptional aerodynamic performance of delta wing-body configurations, the phenomenon of vortex bursting and its influencing factors remain inadequately understood.

Advancements in Hypersaline Wastewater Treatment: The Promise of Quasi‐Liquid Surfaces to Reduce Salt Scaling

Advanced Functional Materials, EarlyView.
Durable quasi‐liquid polymer brush surfaces provide an anti‐scaling strategy for hypersaline brine evaporation and zero‐liquid‐discharge desalination. The smooth, liquid‐like QLS interface suppresses substrate‐side salt nucleation, promotes compact crystallization and dewetting, reduces crystal–surface contact area, and enables low‐adhesion salt ...

On the competition between leading-edge and tip-vortex growth for a pitching plate [PDF]

, 2013
The interaction between leading-edge-vortex and tip-vortex development on a low-aspect-ratio plate has been investigated and compared to a nominally two-dimensional rectangular flat plate.

Mechanically Mutable Matrices: A Hierarchical Investigation of Decellularized Sea Cucumber Collagen as an Adaptable Scaffold Material

Advanced Functional Materials, EarlyView.
Sea cucumber mutable collagenous tissue (MCT) is a remarkable collagen‐based material which can rapidly undergo large changes in stiffness through transiently bound effector proteins. Here, we investigate the hierarchical structure and mechanical response of MCT from Cucumaria frondosa across length scales with a wide range of methods, also exploring ...

Interactions Of A Quasi-two-dimensional Vortex With A Stationary And Oscillating Leading Edge. [PDF]

, 1996
Interactions of a quasi-two-dimensional vortex with a stationary and oscillating leading-edge were examined using a scanning laser version of high-image-density particle image velocimetry (PIV).

Si‐Doped Nanocrystalline Diamond as Highly Sensitive Luminescence Thermometer for the Physiological Temperature Range

Advanced Functional Materials, EarlyView.
In this work, diamonds with negative charged silicon‐vacancy (SiV−) centers have been designed for use as thermometers in biomedical applications. Multiparametric analysis of the emission characteristics of the SiV− centers provides extraordinary sensitivity for temperature detection in the physiological temperature range.
