Liquid-Liquid Phase Separation in an Elastic Network

open access: yes, 2017
Living and engineered systems rely on the stable coexistence of two interspersed liquid phases. Yet surface tension drives their complete separation. Here we show that stable droplets of uniform and tuneable size can be produced through arrested phase ...

Stretching Folding Instability and Nanoemulsions [PDF]

open access: yesarXiv, 2009
Here we show a folding-stretching instability in a microfluidic flow focusing device using silicon oil (100cSt) and water. The fluid dynamics video demonstrates an oscillating thread of oil focused by two co-flowing streams of water. We show several high-speed sequences of these oscillations with 30,000 frames/s.

Driving Micro‐Objects Using Optical Force due to Fluorescence Emission From Molecules

open access: yesAdvanced Optical Materials, EarlyView.
Emission of fluorescence from a micro‐object in a specific direction is expected to generate an optical force driving the object in the opposite direction of the emission, like a rocket. To demonstrate this ‘photon‐driven micro‐rocket’, we prepared dye‐doped polymer micro‐object (PMO) one surface of which was covered with metallic film; the PMO ...

Pressure‐Induced Structural and Optoelectronic Modulations in 2D Dion‐Jacobson Hybrid Lead Iodide Perovskites With a Rigid Spacer

open access: yesAdvanced Optical Materials, EarlyView.
Compression to ≈2.0 GPa results in a non‐monotonic enhancement of the Pb‐I bond distortion, rarely observed in other 2D lead‐iodide hybrid perovskites. The octahedral distortion together with the rigidity of spacer cation are found to play a dominant role in determining the optoelectronic properties of DPDAPbI4 under high pressure.

Water Drop on Thin Viscous Oil Layers: From Stick-Slip Spreading to Dewetting [PDF]

open access: yesarXiv
The impact of water droplets on thin layers of immiscible viscous liquids, such as oil films, is commonly encountered across contexts ranging from kitchen activities to industrial processes. In this study, we experimentally investigate the short-term and long-term behavior of water drops spreading on silicone oil-coated surfaces.

Droplets moving on a fluid surface: interference pattern from two slits [PDF]

open access: yesarXiv, 2013
The Feynman path integral approach for solving the motion of a droplet along a silicon oil surface is developed by replacing the Planck constant by a surrogate parameter. The latter is proportional to the surface tension of the silicon oil multiplied by the area of the thin air film, separating the droplet from the oil, and by the half-period of the ...

Recent Advances in Variable‐Stiffness Robotic Systems Enabled by Phase‐Change Materials

open access: yesAdvanced Robotics Research, EarlyView.
Phase‐change materials (PCMs), such as shape memory alloys, hydrogels, shape memory polymers, liquid crystal elastomers, and low‐melting‐point alloys, are driving advancements in stiffness‐tunable robotic systems across a wide range of applications. This review highlights recent progress in PCM‐enabled robotics, focusing on their underlying mechanisms,
