Title: Method and system for hydrophobic coating of microfluidic chips
Inventor: LARSEN JOHN
IPC: B01L3/00
Filed: 2017-09-12
Abstract: Due to the hydrophilicity of various materials common in microfluidic chip manufacturing, it is difficult to make a microfluidic chip that results in discrete flows from multiple outlets when a liquid is passed through the chip. Provided is a method of providing a hydrophobic coating on a microfluidic chip that promotes discrete flow of at least one liquid. The method includes applying the hydrophobic coating onto an external surface and edges at an outlet region of the microfluidic chip being about 1-2mm away from the tips of a plurality of outlet channels in order to prevent the hydrophobic coating from filling the outlet channels. The hydrophobic coating acts as guides to direct the liquid along the external surface and promotes discrete flow of the liquid by preventing the outlet flow of each of the plurality of outlet channels from merging together after exiting the outlet channels.

Inventor: BAKHAREV S A
IPC: G01S15/04
Filed: 1995-02-23
Abstract: FIELD: hydroacoustics, in particular, parametric reception of audio-frequency signals with the aid of small-sized antennas. SUBSTANCE: hydroacoustic signals are detected when their source is located in the zone of "acoustic shadow" relative to the receiver within a frequency band below 35 Hz, and scanning of the antenna directivity characteristic is accomplished by a relatively simple method in the conditions of a moving carrier. The method is realized as follows. With the aid of n-radiators positioned in a certain manner on the ship hull, oriented in a certain manner relative to the source of audio-frequency signals a radio-frequency pumping signal at n-frequencies (n= 2,4,6,etc.) is radiated into a non-linear water medium in the direction of the sea ground. The radio- frequency pumping signal modulated in amplitude by the audio- frequency valid signal, being scattered by the sea ground, is received by n-receivers positioned in a certain manner on the ship hull. The audio-frequency signal is discriminated from the signal of heterodyne frequencies by the method of amplitude modulation in the multi-channel (n-channels) processing unit. Forming and scanning of the directivity characteristic in the preset plane is accomplished with the aid of a compensator. Carrying out a spectral analysis of signals and comparing the received signal with the reference one, one can take a decision on quantitative and qualitative characteristics of the source of audio-frequency hydro- acoustic radiations. EFFECT: facilitated procedure.
