Sensory comfort evaluation of wool fabrics by objective assessment of surface mechanical properties [PDF]
, 2010 The sensorial comfort is one of the most important aspects of clothing, mainly for next-to-skin garments such as trousers for summer. The perceived comfort of wearers of these garments depends to a great extent on the tactile properties of the fabrics ...

Effects of a nonadiabatic wall on supersonic shock/boundary-layer interactions [PDF]
, 2018 Direct numerical simulations are employed to investigate a shock wave impinging on a turbulent boundary layer at free-stream Mach number M=2.28 with different wall thermal conditions, including adiabatic, cooled, and heated, for a wide range of ...

Physical Intelligence in Small‐Scale Robots and Machines
Advanced Materials, EarlyView.“Physical intelligence” (PI) empowers biological organisms and artificial machines, especially at the small scales, to perceive, adapt, and even reshape their complex, dynamic, and unstructured operation environments. This review summarizes recent milestones and future directions of PI in small‐scale robots and machines.

BLOC: Buildable and Linkable Organ on a Chip
Advanced Materials Technologies, EarlyView.We developed a “Buildable and Linkable Organ on a Chip” (BLOC) that can construct diverse microphysiological systems (MPSs). The BLOC is standardized to the same size and has one of the functions of “Culture,” “Control,” or “Analysis.” Users can freely configure various MPSs, including developing perfusion, cytotoxicity analysis, and biochemical ...

Skin-Friction and Forced Convection from Rough and Smooth Plates
, 2020 The current models for skin-friction drag from a plate with a rough surface are derived by analogy to flow within pipes having rough interiors. But this analogy fails at low Reynolds number (Re) flow rates because the boundary-layer must compress into ...
