For steel castings produced in sand moulds, the expansion of the sand and have a significant impact on the final size and shape of the casting. Experiments are conducted using a cylindrical casting to study this effect for different sands (silica and zircon) and different sand binder systems (phenolic urethane and sodium silicate). The type of sand has a significant effect on the final casting ...
An explanation of the mechanism of irreversible dynamics was offered. The explanation was obtained within the framework of laws of classical mechanics by the expansion of Hamilton formalism. Such expansion consisted in adaptation of it to describe of the nonpotential interaction of a systems. The procedure of splitting of a system into equilibrium subsystems, presentation of subsystem’s energy ...
We present results of anisotropic thermal expansion and low temperature magnetostriction measurements on YNi2B2C single crystals grown by high temperature flux and floating zone techniques. Quantum oscillations of magnetostriction were observed at low temperatures for H‖c starting at fields significantly below Hc2 (H < 0.7Hc2). Large irreversible, longitudinal magnetostriction was seen in both,...
To study the effects of different intravitreal gases on intraocular tissues, adult pigmented rabbits were given 0.4 mL intravitreal injections of air, 50% sulfur hexafluoride (SF6) and air, 100% SF6, 50% perfluoropropane (C3F8), or 100% C3F8. On postinjection days 1, 4, 7, and 14, the eyes were removed and the iris, ciliary body and retina processed for light and electron microscopy. Histopatho...
We report on the impact of differently sized particles on the collapse of a Langmuir monolayer. We use an SDS-DODAB monolayer because it is known to collapse reversibly under compression and expansion cycles. Particles with diameters of 1 μm, 0.5 μm, 0.1 μm, and 20 nm are deposited on the SDS-DODAB monolayer. We find a critical particle size range of 0.1 to 0.5 μm that produces a transition fro...
Abstract Lithium metal is considered as the ‘holy‐grail’ among anode materials for lithium‐ion batteries, but it also has some serious drawbacks such formation of dendritic and dead lithium. In this study, interplay external pressure different carbonate‐ ether‐based electrolytes on (ir)reversible expansion lithium during cycling against titanate iron phosphate studied. carbonate‐based without a...
Lithium-ion batteries cell thickness changes as they degrade. These in consist of a reversible intercalation-induced expansion and an irreversible expansion. In this work, we study the evolution under variety conditions such temperature, charging rate, depth discharge, pressure. A specialized fixture was used to keep cells at constant pressure during cycling, while measuring change both within ...
We derive the Joule expansion of an isolated perfect gas from the principles of quantum mechanics. Contrary to most studies of irreversible processes which consider composite systems, the interesting and ignored degrees of freedom are here described by operators acting in the same many-body Hilbert space. Moreover, the expansion of the gas into the entire accessible volume is obtained for pure ...
in this paper, a new combined power and refrigeration cycle is proposed, which combines the rankin power cycle and the ejector refrigeration cycle. this combined cycle produces both power output and refrigeration output simultaneously. this cycle is driven by the flue gas of gas turbines, industrial waste heats, solar energy and geothermal energy. an exergy analysis is performed to guide the th...
