Tuning high power impulse magnetron sputtering discharge and substrate bias conditions to reduce the intrinsic stress of TiN thin films

Thin Solid Films, 2019
Ion bombardment during film growth usually induces high compressive stress in compound thin film materials, resulting in rupture and failure of coated tools used in tribological applications. Hence‚ intrinsic stress generated during film growth can drastically limit the industrial appeal of deposition technologies such as high power impulse magnetron ...

Experimental and numerical investigation of design optimization of a partial admitted supersonic turbine

Propulsion and Power Research, 2013
To obtain a high specific work output, the large pressure ratios across the turbine are required. This can be achieved using a supersonic turbine. When the fluid mass flow is low, the impulse kind of one or two stages supersonic turbine is employed.

Phase-response analysis of synchronization for periodic flows

, 2018
We apply the phase-reduction analysis to examine synchronization properties of periodic fluid flows. The dynamics of unsteady flows are described in terms of the phase dynamics reducing the high-dimensional fluid flow to its single scalar phase variable.

Evaluation of a pulsed quasi-steady MPD thruster and associated subsystems [PDF]

The performance of quasi-steady magnetoplasmadynamic (MPD) thrusters at high power levels is discussed. An axisymmetric configuration is used for the MPD thruster, with various cathode and anode sizes, over a wide range of experimental conditions. Thrust

A comprehensive test of order choice theory: recent evidence from the NYSE [PDF]

, 2003
We perform a comprehensive test of order choice theory from a sample period when the NYSE trades in decimals and allows automatic executions. We analyze the decision to submit or cancel an order or to take no action.

High-Power Impulse Magnetron Sputter Deposition of Ag on Self-Assembled Au Nanoparticle Arrays at Low-Temperature Dewetting Conditions [PDF]

ACS Applied Materials & Interfaces
Plasmons have facilitated diverse analytical applications due to the boosting signal detectability by hot spots. In practical applications, it is crucial to fabricate straightforward, large-scale, and reproducible plasmonic substrates. Dewetting treatment, via applying direct thermal annealing of metal films, has been used as a straightforward method ...

Characterization of Electromagnetic Properties of In Situ Soils for the Design of Landmine Detection Sensors: Application in Donbass, Ukraine

Remote Sensing, 2019
To design holographic and impulse ground penetrating radar (GPR) sensors suitable for humanitarian de-mining in the Donbass (Ukraine) conflict zone, we measured critical electromagnetic parameters of typical local soils using simple methods that could be
