Surface tension driven transport of liquids on open substrates offers an enabling tool for micro total analysis systems that are becoming increasingly popular low-cost biomedical diagnostic devices. The present study uses a facile wettability patterning method to produce microfluidic tracks - due their shape, surface texture and chemistry capable transporting wide range liquid volumes (~1-500 μL) on-chip, overcoming viscous other opposing forces (e.g., gravity) at the pertinent length...
Dropwise condensation (DWC) heat transfer depends strongly on the maximum diameter (Dmax) of condensate droplets departing from condenser surface. This study presents a facile technique implemented to gain control Dmax in DWC within vapor/air atmospheres. We demonstrate how this approach can enhance corresponding rate by harnessing capillary forces removal examine various hydrophilic–superhydrophilic patterns, which, respectively, sustain and combine filmwise substrate. The material system...
Marine oil spills seriously endanger sea ecosystems and coastal environments, resulting in a loss of energy resources. Environmental economic demands emphasize the need for new methods effectively separating oil-water mixtures, while collecting content at same time. A surface-tension-driven, gravity-assisted, one-step, separation method is presented sustained filtration collection from floating spill. benchtop prototype device uses selective-wettability (superhydrophobic superoleophilic)...
Self-driven surface micromixers (SDSM) relying on patterned-wettability technology provide an elegant solution for low-cost, point-of-care (POC) devices and lab-on-a-chip (LOC) applications. We present a SDSM fabricated by strategically patterning three wettable wedge-shaped tracks onto non-wettable, flat surface. This operates harnessing the wettability contrast geometry of patterns to promote mixing small liquid volumes (µL droplets) through combination coalescence Laplace pressure-driven...
Abstract Preparing surfaces that repel low‐surface‐tension liquids, such as oils and hydrocarbon fuels with surface tensions below 30 mN m −1 , poses more challenges than attaining water repellency. Oleophobic are needed when organic fluids must be contained to avoid pollutant spreading. A composite material system is presented comprised of fluorinated silica (filler), a perfluoroalkyl methacrylate copolymer (binder), polyhedral oligomeric silsesquioxane (additive; considered the lowest...
Humans emit approximately 30 million microbial cells per hour into their immediate vicinity. However, sampling of aerosolized taxa (aerobiome) remains largely uncharacterized due to the complexity and limitations techniques, which are highly susceptible low biomass rapid sample degradation. Recently, there has been an interest in developing technology that collects naturally occurring water from atmosphere, even within built environment. Here, we analyze feasibility indoor aerosol...
Reliable thermal management is a key aspect in the operation of telecommunications equipment, both photonic and electronic. In liquid-cooled management, conventional pump designs incorporate moving parts, introducing reliability concerns. The magnetohydrodynamic (MHD) phenomenon can be used to fabricate highly reliable, compact, solid-state pumps that avoid parts make it suitable for rack level integration equipment. However, pumping efficiency performance limited by pressure losses pump....
