Contactless Detection of Natural Bending Frequencies using Embedded Metallic-Glass Ribbons inside Plastic Beams made of 3-D PrintingAbstract In the current work, 30 micron thin magnetoelastic ribbons made of metallic glass are embedded inside 6 mm thick PLA plastic cantilever beams made by 3-D printing, in order to detect the beams harmonics during bending excitation. This is possible because the ribbons are of magnetoelastic nature an [...] 1193 6735 |
The behaviour of Nitinol Wire Bundles for Structural ApplicationsAbstract Shape memory alloys (SMA) are metallic materials with special thermo-mechanical characteristics which could have many structural applications. Within this class of materials, Ni-Ti (Nickel-Titanium) alloys have numerous applications owing to the significant non-linear behaviour they demonstrate. Nit [...] 1669 12252 |

Abstract Continuous fiber reinforced geopolymer matrix composites offer the potential for use in structural applications at temperatures up to 700°C, while enabling the manufacture at temperatures below 100°C. Studies have investigated a variety of fiber reinforcements, including carbon, SiC and Al2O3. Whi [...] 1447 8515 |
Progress of Nanomaterials in Preventative and Restorative DentistryAbstract To date, many studies have examined the development and use of novel materials, enhancing the performance of existing dental composites and improving methods for restoring tooth structure. In recent years, nanotechnology-based techniques have been used to develop a variety of nanomateria [...] 2166 15236 |

Abstract In this work, two types of wastes were introduced, namely, glass from municipal waste and Construction and Demolition Waste (CDW). The latter, which was obtained from rubble generated by the seismic events occurred in Central Italy in 2016, was introduced in two configurations, the single-layer and [...] 1838 12563 |
High-Performance Polymers for Aeronautic Wires Insulation: Current Uses and Future Prospectsby
Gérald Lopez
Abstract Polymers such as polyimides and fluoropolymers are widely used for insulating aeronautic wires. They are exposed to various changing factors such as temperature, pressure, moisture, vibration, chafing, etc. The electrification on the horizon can potentially increase the demand for these systems. Ind [...] 2650 17888 |

Abstract We fabricated various nanoaperture plasmonic platforms for single-molecule detection. We fabricated nanoapertures like nanopores on a pyramid and nanoslits on an Au flat membrane using a Ga ion focused ion beam drilling technique, followed by irradiating with a high energy electron beam, dependent o [...] 1348 7388 |
Tribological Behaviour of Sputter Coated ZnO Thin FilmsAbstract The tribological properties of ZnO thin film coated on an aluminium work piece by RF magnetron sputtering were studied as a function of deposition power, substrate coating temperature, heat treatment and rotation speed. The variation in the coefficient of friction of ZnO films produced under various [...] 1394 8430 |
Deflection of a Concrete T-beam with Prestressed and Non-prestressed Fiber Reinforcement Polymers at Elevated TemperaturesAbstract Prestressed concrete members have gained popularity as an efficient and effective way of designing a structural member with the best engineering and material properties. The method of prestressing a structural concrete member has the capability of controlling increased service loads with less depth [...] 1394 9440 |
