In this paper, the computational fluid dynamics (CFD) method is applied to the thermal-hydraulic analysis, while the porous media model is used to simplify AP1000 passive residual heat removal heat exchanger tube. The temperature as well as flow distribution in the secondary side of the heat exchanger are obtained, ai…
The fabrication of diffraction gratings of a chirped sampled gratings distributed reflector (CSG-DR) laser by nanoimprint lithography (NIL) has been demonstrated. The diffraction gratings with highly uniform linewidth and period have been successfully fabricated by the combination of the reverse-tone NIL and precise e…
In this paper, a coupled volume-of-fluid and level set (VOSET) method is developed to simulate the two-phase flows. To improve the calculation accuracy of two-phase flows and reduce the cost of computer resources, the dynamically adaptive octree grids are used to refine the grids near the interface. For the deformatio…
As an advanced Gen III+ plant with passive safety systems, the AP1000® plant is uniquely equipped to handle an extended station blackout (SBO) event similar to what occurred at the Fukushima-Daiichi plants in March of 2011. These passive systems have been designed to maintain core cooling for up to 72 hours following…
The CuPL center, a complex of four copper atoms in silicon with the zero-phonon photoluminescence line at 1014 meV and the donor level at 0.1 eV above the top of the valence band, is studied in the process of hydrogenation at 380 K. Complexes of a substitutional copper atom (Cus) with one and two hydrogen atoms are ob…
In this paper, facts are traditionally considered as negative in nuclear related education, e.g. the invisible nuclear radiation, harmful release, even nuclear accidents, are discussed. This paper puts that the factors may let the public be against to nuclear are possible to be converted and improve public acceptance…
Enhanced charge storage performance in AlTi4Ox/Al2O3 multilayer charge trapping memory devices, Gong, Changjie, Ou, Xin, Xu, Bo, Lan, Xuexin, Lei, Yan, Lu, Jianxin, Chen, Yan, Yin, Jiang, Xia, Yidong, Liu, Zhiguo, Li, Aidong, Yan, Feng
A microstructural characterization study was performed on high-pressure die cast specimens extracted from escalator steps manufactured from an Al-12 wt.% Si alloy designed for structural applications. Black and white, color light optical imaging and scanning electron microscopy techniques were used to conduct the micr…
This paper describes the development of glass melter technology, primarily the liquid fed joule-heated ceramic melter process (LFCM) for the vitrificaton of high-level radioactive liquid waste (HLLW) since 1977 in Japan. In 2013 the active test at the vitrification facility (K-facility) in Rokkasho commercial reproces…
The quantitative evaluation of the fission product release to the environment during a severe accident is of great importance. In the present analysis, integral severe accident code MELCOR 1.8.5 has been applied to estimating uncertainty of source term for the accident at Unit 2 of the Fukushima Daiichi nuclear power…
We present a theoretical study of the electronic structures and polarized absorption properties of quantum dot superlattices (QDSLs) using wide–gap matrix material, InAs/In0.48Ga0.52P QDSLs, for realizing intermediate–band solar cells (IBSCs) with two–step photon–absorption. The plane–wave expanded Burt–Foreman operat…
Abstract The selective reduction of nitro compounds by treatment with bimetallic Fe‐Ni nanoparticles (NPs) and tungestophosphoric acid hydrate (H3PW12O40.×H2O) in H2O is reported. The method has been applied to a broad range of nitro compounds with different sensitive functionalities, including halides, carbonyl, hydr…
A novel polyfunctional neutral organophosphorus compound, 2-(diphenylphosphoryl)-N,N-diethyl-3-(1-phenyl-1H-1,2,3-triazol-4-yl)propanamide (I), was synthesized and studied as an extractant for Pd(II), Ln(III), U(VI), and Th(IV) from HNO3 solutions. The influence of aqueous and organic phases on the extraction efficien…
We investigated the photocatalytic inactivation of free Escherichia coli and E. coli attached to carbon particles using granulated activated carbon filter effluent as a water sample. The inactivation rates of both free and attached E. coli exposed to UV/TiO2 were higher than that using UV irradiation alone. However, a…
The present paper describes a first step taken at the Paul Scherrer Institut in the development of a new multi-physics platform for reactor analysis. Such platform is based on the finite-volume software OpenFOAM and aims at a tightly coupled description of neutron transport, thermal mechanics and fluid dynamics. For t…
Liquid lead or lead-based alloy is a potential candidate coolant for fast reactors and ADS subcritical reactors because of its many unique nuclear, thermal-physical and chemical attributes. Chinese Academy of Sciences (CAS) had launched an engineering project to develop ADS system and lead-based reactors. Series CLEAR…
Crystalline InAs films have been prepared directly at room temperature through a new electrochemically induced alloying method by controllably reducing As 2 O 3 dissolved in an alkaline aqueous solution at an indium (In) foil electrode. Steady-state Raman spectra, transmission electron microscopy, and selected area el…
Top-down synthesis of 2D materials from a parent 3D zeolite with subsequent post-synthetic modification is an interesting method for synthesis of new materials. Assembly, disassembly, organisation, reassembly (ADOR) processes towards novel materials based on the zeolite UTL are now established. Herein, we present the…
Subconjunctival/episcleral, intrascleral, and suprachoroidal routes of drug delivery for treatment of posterior segment eye diseases have become more feasible and popular in the past few years. These routes have the advantage of bypassing the main barriers to topical drug penetration, the ocular surface epithelium, th…
We present Raman investigations on lysozyme/trehalose/glycerol solutions at low water content, from room temperature up to the occurrence of the protein thermal denaturation. We studied the Amide I band and the low-frequency spectrum as a function of the glycerol content. The former allows us to monitor the protein un…
