Advanced Materials, EarlyView.Inspired by the octopus and the golden wheel spider, soft robots with liquid crystal elastomer arc fibers as appendages are fabricated to transcend surface constraints through an elevated center of mass and minimal contact footprints. By leveraging curvature‐encoded deformation‐recovery cycles, these robots exhibit contractile, torsional, and flexural ...

Numerical Research on Cooling Performance of Magnetic Nanofluids in a Natural Convection Transformer
Chemical Engineering TransactionsThe transformer is extensively cooled internally by natural convection, which can handle most electrical load conditions and ensure that the maximum internal temperature (hot spot temperature) does not exceed the allowable value.

Covering convection with thermal blankets: fluid–structure interactions in thermal convection
Journal of Fluid MechanicsThe continental plates of Earth are known to drift over a geophysical time scale, and their interactions have led to some of the most spectacular geoformations of our planet while also causing natural disasters such as earthquakes and volcanic activity. Understanding the dynamics of interacting continental plates is thus significant.
