Vapor pressure determination by thermogravimetry
A method for measuring the vapor pressures of a wide range of materials using a conventional thermobalance and standard sample holders is described. The equipment is calibrated using pure reference materials of known vapor pressure and exploiting the relationship between volatilization rate and vapor pressure based on the Langmuir equation for free evaporation. Enthalpies of vaporization and su...
متن کاملNew Evaporation Set-Up for Uranium Compound Targets
Introduction In the past, thin uranium fluoride targets in the form of UF4 on carbon backings were applied for heavy-ion experiments repeatedly. With this compound targets we had several problems: UF4 had to be evaporated on thick carbon substrates of about 45 μg/cm2. The targets were mechanically very fragile and showed heavy sputtering in the beam. The durability of the targets upon irradiati...
متن کاملObtaining Kinetic Parameters by Modulated Thermogravimetry
A new technique, called modulated thermogravimetry, is introduced as a tool for obtaining continuous kinetic information for decomposition and volatilization reactions. The approach makes use of an oscillatory temperature program to obtain kinetic parameters during a mass loss. MTGA may be used under quasi-isothermal conditions to observe a single mass loss or may be combined with linear heati...
متن کاملThe first-principles treatment of the electron-correlation and spin-orbital effects in uranium mononitride nuclear fuels.
The DFT+U calculations were employed in a detailed study of the strong electron correlation effects in a promising nuclear fuel-uranium mononitride (UN). A simple method for solving the multiple minima problem in DFT+U simulations and insure obtaining the correct ground state is suggested and applied. The crucial role of spin-orbit interactions in reproduction of the U atom total magnetic momen...
متن کاملMitochondrial Toxicity of Depleted Uranium: Protection by Beta-Glucan
Considerable evidence suggests that mitochondrial dysfunction contributes to the toxicity of uranyl acetate (UA), a soluble salt of depleted uranium (DU). We examined the ability of the two antioxidants, beta-glucan and butylated hydroxyl toluene (BHT), to prevent UA-induced mitochondrial dysfunction using rat-isolated kidney mitochondria. Beta-glucan (150 nM) and BHT (20 nM) attenuated UA-indu...
