Sentiment analysis of Twitter data is quite valuable for determining the market opinion.
Twitter sentiment analysis is more challenging than generic sentiment analysis owing to …

The classical Hertzian contact model establishes a monotonic correlation between contact
force and area. Here, we showed that the interplay between local friction and structural …

Everyday experience confirms the tendency of adhesive films to detach from spheroidal
regions of rigid substrates—what is a petty frustration when placing a sticky band aid onto a …

Thin elastic films can spontaneously attach to liquid interfaces, offering a platform for
tailoring their physical, chemical, and optical properties. Current understanding of the …

We revisit the delamination of a solid adhesive sheet under uniaxial compression from a flat,
rigid substrate. Using energetic considerations and scaling arguments, we show that the …

The diverse chemical and physical reactions encountered during cooking connect us to
science every day. Here, we theoretically and experimentally investigate the swelling and …

Bio-surfaces are curvilinear and rough. Electronics that can conform to complex three-
dimensional (3D) bio-surfaces hold the key to the next generation bio-integrated electronics …

The injection of a fluid into another fluid causes a spatiotemporal pattern along the injection
front. Viscous fingering is a well-known example when the replaced material is a viscous …

Stretchable and flexible electronic sensors have been attracted to novel applications due to
their conformal integration onto complex curved surfaces, whereas the mounting strains …
