A hydrostatically stressed soft elastic film circumvents the imposed constraint by undergoing
a morphological instability, the wavelength of which is dictated by the minimization of the …

An adhesively stressed thin film of a soft hydrogel confined between two rigid flat substrates
autoroughens with its dominant wavelength (λ) exhibiting pronounced dependence on the …

Nature is filled with various living organisms, ranging from micron scale fungi to large scale
vertebrates, which possess unique adhesion characteristics, including self-cleaning …

Unlike liquids, for crystalline solids the surface tension is known to be different from the
surface energy. However, the same cannot be said conclusively for amorphous materials …

While pressure sensitive adhesives in general consist of a layer of viscoelastic glue
sandwiched between two adherents, we explore here the design of an adhesive embedded …

We study the interaction of small hydrophobic particles on the surface of an ultrasoft elastic
gel, in which a small amount of elasticity of the medium balances the weights of the particles …

We report some experimental observations regarding a new type of long-range interaction
between rigid particles that prevails when they are suspended in an ultrasoft elastic gel. A …

Inspired by recent experiments on hierarchically structured adhesives, we analyze here the
effect of spatial variation in surface topography and shear modulus of an elastomeric …

Large pressures can induce detrimental deformation in micro-and nanofluidic channels.
Although this has been extensively studied for systems driven by pressure and/or capillary …

When two or more closely spaced indenters puncture a soft solid, the puncturing load
diminishes from that required when they are far apart. We have developed a method to …
