We demonstrated the surface functionalization of a highly three-dimensional, superhydrophilic wicking substrate using light to immobilize functional biomolecules for sensor or microarray applications. We showed here that the three-dimensional substrate was compatible with photo-attachment and the performance of functionalization was greatly improved due to both increased surface capacity and re...

We have studied the capillary spreading of a Newtonian liquid along hydrophilic microstripes that are chemically defined on a hydrophobic substrate. The front of the spreading film advances in time according to a power law x=Bt(1/2). This exponent of 1/2 is much larger than the value 1/10 observed in the axisymmetric spreading of a wetting droplet. It is identical to the exponent found for wick...

Owing to their high intrinsic thermal conductivity, carbon nanotubes (CNTs) have previously been incorporated into a variety of thermal management applications to improve cooling performance. Implementation of controlled CNT growth techniques and functionalization methods are applied herein to enhance boiling heat transfer from the porous capillary wicking surfaces widely used in high heat flux...

Magnetic resonance imaging (MRI) and other techniques are being used to investigate moisture transport in textiles. MRI revealed that moisture distribution in carpet is significantly influenced by the details of the vacuum extraction procedure used to remove excess water. Industrially relevant through-flow drying of carpet has been simulated on a laboratory-scale dryer as well as inside an MRI ...

Bioinspired Perspiration Wicking Inspired by the active liquid transport phenomenon in nature, article number 2200961, Hao Wu, Zhuo Li, and co-workers develop a biomimetic Au/TPU/CM based e-skin with dual porosity surface energy gradient to unidirectionally drain sweat away from skin, preventing signal degradation wearing discomfort caused perspiration accumulation.
