Energy Science &Engineering, EarlyView.The novelty of the current study is that the unsteady MHD Cross nanofluid model is, for the first time, coupled with the melting heat transfer at the stagnation point over a horizontally extended cylinder in a Darcy–Forchheimer porous medium. This work connects complex rheological behaviors and phase‐change phenomena in a unique way, with the only ...

Energy Science &Engineering, EarlyView.Three‐turbine guided Savonius arrays installed along highway corridors extract up to 697 J under multi‐vehicle wake conditions when spaced 12 rotor diameters apart—68% more than compact arrangements. Guide vanes boost output by 80–120%, and interior turbines respond most strongly to spacing, governing overall array performance. ABSTRACT Highway‐induced

Synchronization and metachronal waves of elastic cilia caused by unsteady viscous flow
Physical Review ResearchHydrodynamic coordination of cilia is ubiquitous in biology. It is commonly modeled using the steady Stokes equations. The flow around ciliated cells, however, exhibits finite-time vorticity diffusion, requiring a dynamical description.

Exploration, EarlyView.Inspired by the germination of probiotic spores, we utilize the excellent characteristics of spores to break through multiple barriers of oral brain‐targeted delivery. Besides the probiotics mediated gut‐brain communication, the spore coat proteins derived nanosystems with multiple‐barriers‐crossing ability alleviate neurodegeneration.

NOx Formation in Unsteady Counterflow Diffusion Flames
, 2003 The formation of NO and NO2 are sensitive indicators of both temperature and residence time. In this work, the NOx emission index is measured in an unsteady counterflow diffusion flame for methane, propane and ethylene, as a function of average strain ...
