joining of titanium alloys to other materials especially steels has attracted much attention in recent years due to the exceptional properties of titanium such as excellent corrosion resistance and mechanical properties and its increasing application in various industries. according to the fe-ti binary phase diagram, these two elements do not have complete solubility. this leads to difficulties...

Nanobiotechnology has become a resourceful/crucial research area due to their copious applications in industrial, pharmacological and medical fields. In the current study, silver nanoparticles (OFI-AgNPs), gold (OFI -AuNPs) bimetallic alloy (OFI-Ag-AuNPs) were mediated with Opuntia ficus indica (OFI) extract. Evaluation of antioxidant potential biosynthesized was done through total phenolic con...

We study the evolution of silver-rich regions, or ‘clusters’, during making nanoporous gold by dealloying. The clusters, which are remnants master alloy that have evaded corrosion, impact functional behavior material. Furthermore, they carry information on structure size in initial stages Using kinetic Monte Carlo simulations, we emulate electrochemical dealloying at various electrode potential...

We present a case study where we use automated formal analysis to reason about problem-frame concerns. The descriptions of the problem domains, machine and requirements are written in the Alloy language. We show that an evaluation of results and counterexamples provided by a model finder can reveal useful information that can help remove inconsistencies as well as composition errors.

M an’s long history of technologic development has been marked by a continuing search for improved materials. This effort has resulted in vast arrays of new materials which have affected nearly every aspect of contemporary life, including orthodontics. A significant advance in orthodontic materials was made in the late 1930’s and 1940’s when stainless steel wire and appliances became widely ava...

This study evaluated the wear characteristics and bonding to silver-palladium-copper-gold (Ag-Pd-Cu-Au) alloy of an acrylic resin that was filled with pre-polymerized composite particles and initiated with tri-n-butylborane (TBB) derivative (Bondfill). Three methyl methacrylate (MMA)-based resins (Bondfill, Super-Bond, and Multi-Bond II) and a microfilled composite restorative material (Metafil...

Limitations of achieving highly sensitive and stable surface-enhanced Raman scattering (SERS) substrate greatly concern the suitable method for fabrication of large-area plasmonic nanostructures. Herein we report a simple approach using template-based synthesis to create a highly ordered two-dimensional array of gold-silver alloy nanowires, followed by the controlled dealloying process. This pa...
