Abstract A straightforward ferrocyanide immobilization on the surface of graphene oxide (GO) was conducted for rapid and efficient adsorption capacity lanthanum praseodymium from an aqueous solution. The GO mixed with 1-methyl imidazole in presence epichlorohydrin to form GO-imidazole-Cl thereafter suspended a potassium solution fabricate GO-imidazole-FeCN. prepared materials were characterized...

Thermal history and apatite fission-track ages were determined for the Kaleybar, Razgah and Bozqush alkaline intrusions which display Eocene-Oligocene stratigraphic age. These subduction-related intrusions are located in the Alborz-Azarbaijan magmatic belt which is characterized by a Paleogene magmatic flare-up associated with extensional/transtensional tectonism. The mean of Uranium content an...

We introduce a general variational framework to address the tunneling of hot Fermi systems. use representation trace imaginary time $\tau=it$ propagator as functional integral type sum over complete sets states at intermediate propagation slices. assume that these are $\tau$-dependent and generated by an arbitrary trial Hamiltonian $H_0(\tau)$. then convexity inequality derive $H_0(\tau)$ contr...

This paper reviews fission safety design principles and approaches for coupling inertial confinement fusion (ICF) to a subcritical fission blanket, in Laser ICF Fission Energy (LIFE) power plants. LIFE power plants use fuel derived from either spent fuel from fission reactors, or from natural uranium or thorium. By using fusion neutrons, LIFE plants can fission a large fraction of the heavy met...

As a droplet moves, due to evaporation at the surface, the droplet size is gradually reduced. Due to decreasing the size of the droplets moving in the spray core, the surface charges become closer and the repulsive force between the charges increases. When the Coulombic force overcomes the surface tension force (Rayleigh instability) the droplet breaks into smaller droplets (Coulomb fission). T...

We investigate the formation and the decay of heavy systems which are above the fission barrier. By using a microscopic simulation of constraint molecular dynamics (CoMD) on Au+Au collision, we observe composite states stay for very long time before decaying by fission. The typical reaction mechanisms of heavy-ion collisions at lower incident energy are, depending on the energy and impact param...

Nuclear transmutation has been reported by lots of experiments. The features of this phenomenon are the production of elements which shows fission-like distribution and their anomalous isotopic ratios or the selective Z and mass changes [1]. To analyze this phenomenon, the selective channel scission (SCS) model has been proposed and improved [2]. The SCS model is powerful and can predict the fi...
