The enthalpies of formation of the intermetallic compounds in the Ge-Ni binary system have been determined by calorimetric measurement and first-principles calculations. Based on the results obtained and information available in the literature, the phase d ...
We study experimentally the acoustic response of a load-bearing, phononic crystal composed of alternating steel disks and polytetrafluoroethylene o-rings under precompression. The crystal allows for axial, rocking, and shear-polarized wavemodes when excite ...
Analytical ultracentrifugation (AUC) primarily serves to investigate hydrodynamic and thermodynamic properties of natural and synthetic macromolecules and colloids in solution, dispersion or suspension. Beside such more conventional use, AUC can support ma ...
Experimental evidence in the literature suggests that foil bearing supported rotors can suffer from sub-synchronous vibration. While dry-friction between top foil and bump foil is thought to provide structural damping, sub-synchronous vibration is still an ...
One of the main causes of damages for wind-turbine power plants is lightning. Direct and indirect events, indeed, can produce damages and malfunctions of electrical and mechanical components. Concerning mechanical components, blades and bearings are the mo ...
The temperature behavior of the generation of the second acoustic harmonics induced by an electric field during the transition of a crystal to the ferroelectric state has been considered based on the thermodynamic approach in the framework of the Landau mo ...
Driven by applications using herringbone grooved bearings lubricated with a gas operating under conditions where the perfect gas assumption is not valid, the real gas effect has been introduced into the existing narrow groove theory. The enhanced model has ...
The high energy of hydrogen vibrations in solids is the origin of their strong impact on thermodynamic properties. The peculiar structure of complex hydrides amplifies this impact. We shed light on the vibrational properties of three allotropes of Ca(BH4)2 ...
Gas Lubricated Herringbone Grooved Journal Bearings (HGJB) have long been used in equipment such as navigation systems, optical scanners for laser printers and high speed cameras and disk spindle for flyhead testers. All such applications are characterized ...
We study the thermodynamic stability at low temperatures of a series of alkali-metal-zinc double-cation borohydrides, including LiZn(BH4)(3), LiZn2(BH4)(5), NaZn(BH4)(3), NaZn2(BH4)(5), KZn(BH4)(3), and KZn2(BH4)(5). While LiZn2(BH4)(5), NaZn(BH4)(3), NaZn ...
