Study on Pressure Fluctuation Characteristics of Hydraulic Pulsed Jet
Shiyou jixie, 2016 By producing instantaneous negative pressure and pulse shock at the bottomhole,the pulsed jet could reduce the pressure holding effect on the cuttings and improve the efficiency of rock breaking and cutting removing.On the basis of the established ...

Multifunctional Microstructured Surfaces by Microcontact Printing of Reactive Microgels
Advanced Functional Materials, EarlyView.Reactive poly(N‐vinylcaprolactam‐co‐glycidyl methacrylate) microgels are used as functional inks to create surface‐grafted arrays on glass via microcontact printing. The patterns (10–50 µm widths and spacings) enable stable binding and post‐functionalization with dyes and peptides.

Effects of sidewall geometry on the installed performance of nonaxisymmetric convergent-divergent exhaust nozzles [PDF]
The investigation was conducted at static conditions and over a Mach number range from 0.6 to 1.2. Angle of attack was held constant at 0 deg. High pressure air was used to simulate jet exhaust flow at ratios of jet total pressure to free-stream static ...

Three‐dimensional Antimony Sulfide Based Flat Optics
Advanced Functional Materials, EarlyView.This work presents the development of a grayscale electron beam lithography (g‐EBL) method for fabricating antimony trisulfide (Sb2S3) nanostructures with customizable 3D profiles. The refractive index of g‐EBL patterned Sb2S3 is determined based on the synergy of genetic algorithm and transfer matrix method.

INCREASE IN TRACHEAL PRESSURE DURING JET VENTILATION
British Journal of Anaesthesia, 1989 Gas injection systems used in several techniques of ventilation cause increases in airway pressure and physiological changes which are frequently overlooked. The momentum flux theory describes such phenomena most appropriately. We have defined and measured the characteristics of such increases in airway pressure, using a lateral tracheal injection ...

Two Types of Magnetohydrodynamic Sheath Jets
, 2009 Recent observations of astrophysical jets emanating from various galactic nuclei strongly suggest that a double layered structure, or a spine-sheath structure, is likely to be their common feature.
