Vibrating lubricant-infused porous surface for enhanced liquid droplet transport
… porous surfaces (SLIPS) demonstrate extreme liquid repellency such that a droplet immiscible with the lubricant can roll off at a very small tilt angle < 5°. There have been many applications in using SLIPS to achieve complex fluids handling, anti-fouling, self-cleaning, anti-icing, and …

Modelling of liquid droplet dynamics in a high DC magnetic field
The oscillating droplet technique is an experimental technique that is used to measure the surface tension and viscous damping coefficients of a liquid droplet. This technique has been the subject of much analysis; theoretical, numerical, and experimental with a number of different external forces …

A deep dive into the liquid droplet state of α-synuclein
… shedding light on its transition from liquid droplets/condensates to amyloid-rich hydrogels reminiscent of Lewy bodies. Utilising both in vitro assays and a Caenorhabditis elegans model of PD, we elucidate the influence of cellular components on the maturation of α-synuclein condensates …

Exploration of a liquid droplet state for α-synuclein in vitro and in vivo
… that many proteins can phase separate into dense droplets with liquid properties. Aberrant phase separation facilitates the formation of amyloid and intracellular inclusions. As such, we proposed that phase separation by a-synuclein into a liquid droplet state is a critical step in the formation …

Micro-textured surfaces for omniphobicity and drag-reduction
When a liquid droplet contacts a surface possessing the appropriate combination of surface texture and solid surface energy, the liquid may not penetrate into the surface texture. Instead, the droplet sits partially on air, forming a solid-liquid-air composite interface. Entrapped air pockets of …

Parametric studies on dropwise condensation heat transfer
Wettability of a solid surface with liquids could be tuned based on surface morphologies. This is significant in condensation heat transfer. Condensation is a critical heat transfer mechanism in industrial processes; Dropwise (DWC) and Filmwise (FWC) condensation processes are important and are …

Condensation Frosting: From Ice Bridges to Dry Zones
… during condensation frosting each supercooled droplet in the condensate population freezes in isolation by heterogeneous nucleation at the solid-liquid interface, quite analogous to the mechanism of icing. This assumption has very recently been invalidated with strong experimental evidence …

Capillary Force in High Aspect-Ratio Micropillar Arrays
… micropillar arrays. We have shown that when a liquid is evaporated off the micropillar arrays, the pillars bend and cluster together due to a much smaller capillary meniscus interaction force while still surrounded by a continuous liquid body, rather than due to often reported Laplace pressure …

Analysis of heat transfer and fluid flow in an evaporating sessile droplet for evaporative cooling applications
… technology. The evaporation of the sessile liquid droplet facilitates the phase change of that liquid and provides cooling to the system, because a large amount of latent heat is required to change the phase. Evaporation takes place at the liquid-vapour interface, so to enhance the phase …

Experimental studies of liquid marbles and superhydrophobic surfaces
The interaction of water droplets with hydrophobic or rough, superhydrophobic solid surfaces has been studied. Such surfaces may be found in the natural world and their potential applications range from waterproof and self-cleaning surfaces to droplet microfluidics. A measure of hydrophobicity is …

Phase transfer in a collision between a droplet and solid spheres
The hydrodynamics of a liquid droplet impinging on a particle is of direct relevance to many engineering applications. The mechanism of heat and mass transfer during the droplet solid collision is essential to the design and operation of many industrial systems. However, very limited systemic …

The impact of Arctic cloud water and ice on cloud radiative forcing during the Arctic Summer Cloud-Ocean Study in August 2008
… are used together to constrain estimates of liquid droplet radius; constraining these radii shows the sensitivity of shortwave cloud radiative forcing and the insensitivity of long wave cloud forcing to changes in drop size.

Micron-scale thermistors for rapid transients in interfacial temperature
The shape of freezing droplets is controlled by the motion of the molten interface, or contact line, between the liquid droplet and the solid target. The solution for the heat transfer between the liquid and solid has an analytical singularity at the contact line. We therefore wish to closely …

Voltage induced spreading and liquid optical devices
… investigation has been carried out into Liquid dielectrophoresis (LDEP), in which dielectric forces are used to actuate bulk liquid spreading and to imprint a deformation pattern at a liquid air surface. Our basic conguration uses a set of co-planar stripe interdigital electrodes to …

A microfluidic culture for two populations of dorsal root ganglia for differential staining

Fiber Optic Sensors for Liquid Identifications

The acceptability of alcohol fuels for automobile engines
… was determined that a `take off' of about 5% v/v liquid in the vapour phase would be sufficient for starting. Additions such as iso-pentane and n-pentane were used to improve the front end volatility. This proved to be successful.The lower heat content of the alcohol fuels also meant that a …
