BACKGROUND About half of the orthodontists recycle and reuse orthodontic wires because of their costs. So when talking about reuse and sterilization of wires, their effects on mechanical properties of wires should be clarified. The purpose of this study was to assess the effects of sterilization and clinical use on mechanical properties of stainless steel wires. MATERIALS AND METHODS Thirty s...

E lectrical wires transport energy and information and often both. For example, electrical power cords deliver electrical energy from wall outlets to computers, whereas Ethernet cable transports information in the form of electrical pulses from the internet modem to the computer and back. USB cables are used to both charge the battery of MP3 players and to load digital music on the player. Desp...

A failure assessment method of stay cables containing fractured wires is presented through an example of an existing bridge. The wires constituting the stay cables of the bridge contained many initial defects that were formed during the rolling process of these wires. Despite moderate loading, fatigue cracks started to grow from these defects, increasing their size, and finally resulting in fra...

When analyzing reliability, wires have in most cases been ignored, with gates (and devices) taking the lion’s share. With scaling, this “only computing fails” approach is not going to be accurate enough as communication (wires) will also start to err. Trying to do justice to wires, this paper details a statistical failure analysis of wires following on the few papers which have made wires’ reli...

Metallic molybdenum (Mo(o)) wires with diameters ranging from 15 nanometers to 1.0 micrometers and lengths of up to 500 micrometers (0.5 millimeters) were prepared in a two-step procedure. Molybdenum oxide wires were electrodeposited selectively at step edges and then reduced in hydrogen gas at 500 degrees C to yield Mo(o). The hemicylindrical wires prepared by this technique were self-uniform,...

One-dimensional metal wires are valuable materials because of their optical and electronic anisotropy, and they have potential utility in devices such as photovoltaic cells and molecular sensors. However, despite more than a century of research, only a few examples exist of well-defined one-dimensional (1D) metal wires that allow for the rational variation of conductivity. Herein we describe th...

Oil-impregnated paper is widely used in power transmission equipment as a reliable insulation. However, copper sulphide deposition on oil-paper insulation can lead to insulation failures in power transformers. This paper presents the influences of copper sulfur corrosion and copper sulphide deposition on copper wires and oil-paper insulation in power transformers. Thermal aging tests of paper-w...

AIM The purpose of this study was to evaluate the load and unload deflection and permanent deformation of round 0.016'' and rectangular 0.016'' × 0.022'' regular and coated Ni-Ti wires. MATERIALS AND METHODS Ni-Ti archwires produced by two manufacturers were evaluated. Both regular and coated round and rectangular Ni-Ti wire segments (n = 15) from each group were submitted to a three-point be...
