The properties of thin films are often influenced by the crystal’s preferred orientation. In present study, we report strong dependence surface conductivity on orientation TiN film that acts as coating material for Ti bipolar plate. is successfully controlled along (111) or (200) planes adjusting N2 flow rate substrate temperature during deposition process via DC (direct current) reactive magne...

The bipolar plate is the fundamental structural element of hydrogen fuel cell, and its flow field design has a significant impact on performance cell. cell employed as an important energy supply source for vehicle power. classification operation cells, well benefits drawbacks conventional fields, are discussed in this paper contrasted with state research recent years. Comprehensive analysis don...

In this research study, we present a novel frame work for handling bipolar fuzzy soft information by combining bipolar fuzzy soft sets with graphs. We introduce several basic notions concerning bipolar fuzzy soft graphs and investigate some related properties. We also consider the application of the bipolar fuzzy soft graphs. In particular, three efficient algorithms are developed to solve mult...

The LCLS photocathode rf gun requires a solenoid immediately downstream for proper emittance compensation. Such a gun and solenoid have been operational at the SSRL Gun Test Facility (GTF) for over eight years. Based on magnetic measurements and operational experience with the GTF gun solenoid multiple modifications are suggested for the LCLS gun solenoid. The modifications include adding dipol...
