In this paper, we discuss nanoliter metering, transportation, merging, and biochemical reaction on a nanoliter fluidic chip. The proposed nanoliter fluidic handling is based on passive fluidic control using hydrophobic valving and liquid flow control by selective wettability patterning. For the selective patterning of the wettability, a hydrophobic fluorocarbon (FC) film (a mixture of FluoradTM...

Wave lensing produces the highest level of transient solar irradiances found in nature, ranging in intensity over several orders of magnitude in just a few tens of milliseconds. Shallow coral reefs can be exposed to wave lensing during light-wind, clear-sky conditions, which have been implicated as a secondary cause of mass coral bleaching through light stress. Management strategies to protect ...

Sprinkler irrigation is a common farming practice in those states where the semi-arid climate and lack of sufficient rainfall during critical growing periods necessitate the use of supplemental water. The source of most irrigation water is groundwater which can be contaminated with volatile organic compounds (VOCs). Since the groundwater may be the primary or only source of drinking water for a...

We present a laterally emitting, coupled cavity micro fluidic dye ring laser, suitable for integration into lab-on-a-chip micro systems. The micro-fluidic laser has been successfully designed, fabricated, characterized and modelled. The resonator is formed by a micro-fluidic channel bounded by two isosceles triangle mirrors. The micro-fluidic laser structure is defined using photo lithography i...

J. Econ. Entomol. 72: 261-264 (1979) Potatoes grown under furrow irrigation sustained over 58 times greater infestation by Phthorimaea operCIIlella (Zeller) and 3 times more green tubers than potatoes grown under sprinkler irrigation even though foliage tuberworm populations, soil type, and soil moisture levels were similar. Water usage on a per ha basis was more efficient under sprinkler irrig...

The concept of fluidic multipoles, in analogy to electrostatics, has long been known as a particular class of solutions of the Navier-Stokes equation in potential flows; however, experimental observations of fluidic multipoles and of their characteristics have not been reported yet. Here we present a two-dimensional microfluidic quadrupole and a theoretical analysis consistent with the experime...

Due to the lack of continuous flows that would wash unwanted specifies and impurities off from a target location, droplet microfluidics commonly employs a long serial dilution process to purify target species. In this work, we achieve high-purity separation for the case of electrowetting-on-dielectric (EWOD) based droplet microfluidics by introducing a "fluidic conduit" between a sample droplet...

The article describes design and realization of an airflow structure for measurement. There are structure and electronic circuits design in the paper are described The principle of a flowmeter sensor operation is based on the mechanism of a fluidic oscillator. It uses fluidic paths in feedback. Oscillator samples have been made using different technologies and materials. Micromechanical shaping...
