The high-temperature irradiation-resistant thermocouple is the only temperature probe proven to withstand (>1290°C), high-radiation (a fluence of up ?1 × 10 21 n/cm 2 ) environments nuclear reactor fuel design testing and/or over-temperature accident conditions. This report describes improved performance a molybdenum and niobium by utilizing coaxial (i.e., single wire grounded outer sheath)....

The modeling of single core cable has an important influence on the calculation sheath cross-connected grounding current and voltage. A suitable equivalent circuit can greatly reduce complexity model. In this paper, theoretical π type is analyzed, system analyzed. Then equation circulation induced voltage obtained. Finally, by simulating two kinds faults, fault location are summarized.

Particle energization in shear flows is invoked to explain non-thermal emission from the boundaries of relativistic astrophysical jets. Yet, physics particle injection, i.e., mechanism that allows thermal particles participate shear-driven acceleration, remains unknown. With particle-in-cell simulations, we study development Kelvin-Helmholtz (KH) instabilities seeded by velocity between a magne...

In this paper, Fe 3 O 4 @SiO 2 core/shell magnetic nanostructure has been synthesized and modified by N-(2-aminoethyl)-3-aminopropyltrimethoxysilane (AEAPTMS). Fe 3 O 4 @SiO 2 was used as a novel adsorbent for separation of hexachloroplatinic acid.X-ray diffraction (XRD), scanning electron microscopy (SEM), and FT-IR technique were used to characterize morphologies and surface te...

By coupling of Fe2O3@SiO2 particles with metal organic Framework (MOF) the magnetic MOF structure was fabricated. Precipitation and hydrothermal methods were applied for synthesis of core and MOF. Silver nanoparticles were deposited on nickel based metal organic framework surface and magnetic Fe2O3@SiO2@MOF@Ag was obtained. Because of strong coupling between silver nanoparticles and metal organ...

Cellulose nanofibers (CNFs) are of interest as load-bearing components for polymer matrix nanocomposites. A wide range of nanostructured materials including nanopaper/films, foams, aerogels, and hydrogels can be prepared from CNFs. The material performance can be fine-tuned when CNFs are combined with different polymer matrices. The main idea of the present study is to test the hypothesis that ...

In the past decades, in response to the energy needs of modern society and emerging ecological concerns, the pursuit of novel, low-cost, and environmentally friendly energy conversion and storage systems has raised significant interest. Among these systems, fuel cells have gained much attention for their high efficiency and high power density, with low greenhouse gas emission. As one of the mos...
