In the present study, the corrosion behavior of AISI 347 austenitic stainless steel to ASTM A335 low alloy steel dissimilar joint was investigated. For this purpose, two filler metals, ER309L and ERNiCr-3, were selected to be used during the gas tungsten arc welding process. To investigate the corrosion behavior of the joints after welding, the specimens were tested in 3.5% sodium chloride solu...

The formation of oxides on the surface of the metal are proven to contribute to the formation of strong bonding. However, The base metal alloys are expected to exhibit more oxidation than high gold alloys, increase in oxide layer thickness due to repeated firing in them can reduce the bond strength. The aim of this study was to compare the effect of repeated porcelain firing on the bond strengt...

The first-ever peptide biomaterial discovery using an unconstrained engineered bacterial display technology is reported. Using this approach, we have developed genetically engineered peptide binders for a bulk aluminum alloy and use molecular dynamics simulation of peptide conformational fluctuations to demonstrate sequence-dependent, structure-function relationships for metal and metal oxide i...

Large area fabrication of metal alloy nanoparticles with tunable surface plasmon resonances on low-cost substrates is reported. A UV excimer laser was used to anneal 5 nm thick Ag Au bilayer films deposited with different composition ratios to create alloy nanoparticles. These engineered surfaces are used to investigate how the wavelength of the surface plasmon resonance affects the optical det...

The metal-insulator transition (MIT) caused purely by alloy disorder in a Zno 3Cdo 7Se semiconductor alloy has been probed by using persistent photoconductivity. Key parameters that describe the MIT, including the critical electron concentration n, and the energy tail states distribution parameter Eo, have been determined experimentally. Our results, together with those obtained for impurity-do...
