摘要:
A method of etching capable of rapidly and flatly performing wet etching on a Si substrate using fluonitric acid represented by HF(a)HNO3(b)H2O(c) (where the unit of a, b and c is wt % and a+b+c=100). The etching rate of an SiO2 layer with the highly concentrated fluonitric acid is significantly lowered by the appropriate selection of its composition as compared with the etching rate of the Si substrate, and etch the Si substrate until the SiO2 layer is exposed. In this way, it is possible to rapidly etch the Si substrate and significantly enhance the flatness of the etched surface.

A blood storage system. The system has a collection bag for red blood cells; an oxygen/carbon dioxide depletion device; a storage bag for red blood cells; and tubing connecting the collection bag to the depletion device and the depletion device to the storage bag. The depletion device includes a receptacle of a solid material having an inlet and an outlet adapted to receiving and expelling a flushing gas; a plurality of hollow fibers or gas-permeable films extending within the receptacle from an entrance to an exit thereof. The hollow fibers or gas-permeable films are adapted to receiving and conveying red blood cells.

摘要:
A substrate supporting apparatus for supporting a substrate or wafer in a non-contact state by Bernoulli theorem is disclosed. The substrate supporting apparatus 1 comprises a housing 2, a rotatable chuck 3 which is disposed in the housing 2, which is provided at its central portion with a hollow 12 and which supports a substrate 6, and a cylindrical nozzle member 4 which is disposed in the housing 2, which has a nozzle hole 7 and which can vertically move in the hollow 12. A nozzle hole 7 is formed in a central portion of the nozzle member 4. Gas is discharged from a gas source 8 through the nozzle hole 7, thereby holding the substrate 6 by an upper surface of the chuck 3 in a non-contact state. When the substrate 6 is to be detached, the nozzle member 4 is moved upward while discharging gas from the nozzle hole 7, thereby floating the substrate 6.

摘要:
A system for assessing the microvascular fitness of a sample of stored red blood cells. The system has a network device having at least one network unit. The network unit has a single inlet and a single outlet for the sample and a plurality of microchannels. The plurality of microchannels receive the sample from the single inlet and drain the sample into the single outlet. The network unit includes an aspiration pressure means for providing movement of liquid sample through the at least one network unit. The system further includes an analysis unit that receives the network device therein. The analysis unit includes a sensor for capturing measurements related to the sample and a processor capable of comparing the captured measurements to measurements stored in a database of healthy red blood cells to determine the microvascular fitness of the stored red blood cells.
