We propose a stable numerical scheme for a Cahn-Hilliard type equation with long-range interaction describing the micro-phase separation of diblock copolymer melts. The scheme is designed by using the discrete variational derivative method, one of structure preserving numerical methods. The derivation of the discrete…

We prepared titanosilicate glasses by the sol–gel method and studied its ability to disperse Ca-α-SiAlON:Eu2+ phosphor, which is a typical yellow phosphor and applicable for white light-emitting diodes (LEDs). xTiO2–(100 − x)SiO2 glasses dispersed with SiAlON powders were obtained by sintering at 900°C with x ranging…
Two groups of cadmium selenide thin films deposited at 25 0 C and 74 0 C respectively on glass substrates by chemical bath deposition method were studied. A moderately stable sodium selenosulphite (Na 2 SeSo 3 ) was used as a source of Se 2- ions. To prevent spontaneous precipitation and ensure ion-by-ion deposition o…
Mn/Y co-doped Ba0.67Sr0.33TiO3 (BST: Mn+Y) thin films were deposited on LaNiO3 (LNO)/SiO2/Si substrates by radio frequency (RF) magnetron sputtering technique, and the films were annealed subsequently at different temperatures. X-ray diffraction (XRD) demonstrated that all films are polycrystalline with a perovskite s…
The Physical Model (PM) is an internal multi-Volume document for the IAEA’s Department of Safeguards describing the nuclear fuel cycle. This report describes work carried out by the JRC with the IAEA to prototype the integration of the PM with The Big Table (TBT), a document search tool developed by the JRC and in use…
