Effects of the hydrophobic coating on the initiation of frost formation.
… freezing process of water droplets forming on hydrophobic coated surface were investigated by using a digital high-speed microscopy system. The images indicated that hydrophobicity of surfaces can affect the fusion of inter-droplets to form some relative dry areas between droplets and further …

Mass transfer diffusion coefficient as a proxy for hydrophobic coating durability
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2026-05-01

Experimental and numerical investigation of the flow structures at the rear of three-dimensional bluff bodies
… × 105. In the second method, the effect of a hydrophobic coating on the flow structure of the SAB and EAB is investigated experimentally using the PIV technique and for the same Reynolds numbers stated above. For both methods, the coherent structures are evaluated using advanced analysis …

Hydrophobic coatings for film boiling based drag reduction on a torpedo model
Previous research has shown that porous, hydrophobic surfaces exhibit a dramatic reduction in critical heat flux (CHF), the amount of heat over a surface area required to initiate film boiling. Film boiling is characterized by the presence of a vapor layer which remains as long as the surface …

High speed air pneumatic wind shield wiping design
… showed potential especially when coupled with a hydrophobic coating covering the windshield. The design using the high-speed squirrel cage blowers was implemented on an actual car in which it revealed positive results, which will be further assessed for patenting potential.

STUDIO DELLA COMPOSIZIONE CHIMICA DEL DEPOSITO DI PARTICOLATO ATMOSFERICO E DELLA SUA INFLUENZA SULLA CONDUCIBILITÀ ELETTRICA DEGLI ISOLATORI DELLA RETE DI TRASMISSIONE
… vertical profile of and the presence of a hydrophobic coating were the studied factors. Weathering effect was predominant and synergic with the complex system of phenomena in act: vertical profile was in fact responsive to rain wash-off, while correlation with face factor was masked. The …

Optimization of hydrophobic meshes for oil spill recovery
… development of functionalized steel meshes with hydrophobic and oleophilic surfaces. These meshes can perform oil/water separation in situ, continuously, via capillary action. The goal of this study is to determine the potential of hydrophobic meshes as oil spill recovery devices. A fabrication …

Sessile Droplet Microfluidic Platforms for Improvements in Mass Spectrometry Sample Preparation
… be made rapidly and reproducibly by applying a hydrophobic coating to a glass surface, then milling surface energy traps (SETs) into the surface using picosecond laser micromachining. Resulting SETs serve as anchor points to hold liquid droplets and can be filled spontaneously by discontinuous …

Impact of pre-acidification, fat replacers and exopolysaccharide producing starter cultures on functionality of low fat mozzarella cheese
… of low fat Mozzarella cheeses (including coating the surface of cheeses with a hydrophobic coating of oil) made by combining the use of EPS producing starter cultures, pre-acidification of cheese milk with citric acid to pH 6.1 and co-culturing and supplementation with WPC (as identified …

Force and Energy Measurement of Bubble-Particle Detachment
… (KSV Sigma 70 tensiometer) and using a submerged hydrophobic plate in water. Three experiments were used; direct force measurement of bubble-particle detachment, detachment force and energy of a bubble from a submerged hydrophobic plate, and detachment force and energy of a cetyltrimethylammonium …

Design and Fabrication of Out-of-Plane Silicon Microneedles with Integrated Hydrophobic Microchannels
… with inner structures as a method of creating hydrophobic surfaces on the inner walls of the channels. It was found that the channels developed had far too much variability in the diameter to accurately create a measurable reduction in flow; however, a loss coefficient was calculated showing …

Analysis of Viscous Drag Reduction and Thermal Transport Effects for Microengineered Ultrahydrophobic Surfaces
… on the channel walls. When treated with a hydrophobic coating, the liquid flowing in the microchannel wets only the top surfaces of the ribs, and does not penetrate into the cavities, provided the pressure is not too high. The net result is a reduction in the surface contact area between …

Introduction of a thermo-sensitive non-polar species into polyelectrolyte multilayer capsules for drug delivery
… charged wax particles. The incorporation of this hydrophobic coating leads to a reduced water sensitivity particularly after heating, which melts the wax, forming a barrier layer. This conclusion was proven with Neutron Reflectivity by showing the decreased presence of D2O in planar …

Numerical Study of Fully Developed Laminar and Turbulent Flow Through Microchannels with Longitudinal Microstructures
… in the channel wall that are then treated with a hydrophobic coating. Such surfaces have been termed super- or ultrahydrophobic and the contact area between the flowing liquid and the solid wall is greatly reduced. Further, due to the scale of the micropatterned structures, the liquid is unable to …

Environmental consequences associated with ash-stabilisation of organic sludges from the synthol process
… of the toxicity of synthol gunk is due to the hydrophobic coating of roots resulting in inadequate water intake by the plant.
