Electric field induced reversible spreading of droplets into films on lubricant impregnated surfaces [PDF]
Electric fields can be used to force a droplet to wet a solid surface using an applied voltage. However, significant hysteresis usually occurs associated with pinning forces at the contact line.

Wetting of doubly periodic rough surfaces in Wenzel’s regime
In this work we present preliminary results from our numerical study of the shapes of a liquid meniscus in contact with doubly sinusoidal rough surfaces in Wenzel’s wetting regime.

Plastron induced drag reduction and increased slip on a superhydrophobic sphere [PDF]
On low contact angle hysteresis superhydrophobic surfaces, droplets of water roll easily. It is intuitively appealing, but less obvious, that when such material is immersed in water, the liquid will flow more easily across its surface.

Closed-Form Expressions for Contact Angle Hysteresis: Capillary Bridges between Parallel Platens
A closed form expression capable of predicting the evolution of the shape of liquid capillary bridges and the resultant force between parallel platens is derived. Such a scenario occurs within many micro-mechanical structures and devices, for example, in

Micro to nano: Surface size scale and superhydrophobicity
This work looks at the fundamental question of how the surface mobility of drops in the composite state is related to the size scale of the roughness features of the surface.

Numerical Study of Drop Motion on a Surface with Wettability Gradient and Contact Angle Hysteresis
In this work, the motion of a 2-D drop on a surface with given wettability gradient is studied numerically by a hybrid lattice-Boltzmann finite-difference method using the multiple-relaxation-time collision model.

Kinetics of Wetting and Spreading of Droplets over Various Substrates [PDF]
There has been a substantial increase in the number of publications in the field of wetting and spreading since 2010. This increase in the rate of publications can be attributed to the broader application of wetting phenomena in new areas.

Aloe vera for Dry Mouth Denture Patients – Palliative Therapy [PDF]
Introduction: Xerostomia (dry mouth) is dryness of the mouth which is due to reduced salivary flow. Lack of adequate saliva causes discomfort in denture wearing patients and decreases retention of dentures.
