3D Propulsions of Rod‐Shaped Micropropellers
Advanced Intelligent Systems, 2021 Untethered, magnetically driven microrobots have great potential in practical applications such as minimally invasive surgery. Microrods, also known as “nanowires,” are the most commonly used type of structure for microrobots due to the easy fabrication ...

Turbulent diffusion of chemically reacting gaseous admixtures [PDF]
Physical Review E, Volume 90, Issue 5, id.053001 (2014), 2014 We study turbulent diffusion of chemically reacting gaseous admixtures in a developed turbulence. In our previous study [Phys. Rev. Lett. {\bf 80}, 69 (1998)] using a path-integral approach for a delta-correlated in time random velocity field, we demonstrated a strong modification of turbulent transport in fluid flows with chemical reactions or phase ...

Chloride‐Mediated Electron Buffering on Ni‐Fe Anodes for Ampere‐Level Alkaline Seawater Electrolysis
Advanced Functional Materials, EarlyView.Utilizing abundant chloride ion (Cl−) of seawater, the small organic molecule (SOM) layer on the electrocatalyst surface is converted to SOM‐Cl layer. Meanwhile, the conjugated structure of SOM is modified. SOM‐Cl layer can effectively mitigate the damage caused by the highly oxidative environment.

On two distinct Reynolds number regimes of a turbulent square jet
Theoretical and Applied Mechanics Letters, 2015 The effects of Reynolds number on both large-scale and small-scale turbulence properties are investigated in a square jet issuing from a square pipe. The detailed velocity fields were measured at five different exit Reynolds numbers of 8×103≤Re≤5×104. It

Properties and selected implications of magnetic turbulence for interstellar medium, Local Bubble and solar wind [PDF]
, 2008 Astrophysical fluids, including interstellar and interplanetary medium, are magnetized and turbulent. Their appearance, evolution, and overall properties are determined by the magnetic turbulence that stirs it. We argue that examining magnetic turbulence at a fundamental level is vital to understanding many processes.

Influence of Flow-induced Vibration of a D-VAWT With and Without Leading-edge Rod at Various Pitch Angles [PDF]
Journal of Applied Fluid MechanicsUnder specific incoming wind speeds, Darrieus- Vertical Axis Wind Turbines (D-VAWT) have been found to display significant amplitude vibrations. Previous studies mainly examined the D-VAWT's aerodynamics, ignoring flow-induced vibration (FIV).
