This PhD focuses on the relationship between the preparation process and the structure of polypropylene/clay nanocomposites. First, the samples were prepared via an internal mixer. Scanning electron microscopy observations, completed by X-ray diffraction analysis and rheology measurements enabled us to characterize th…
Abstract For the safety of spent nuclear fuel assemblies stored in storage pool in the extreme condition where the water is lost completely, a passive spray cooling technique was designed, and its effectiveness has been validated by a functional experiment. The spray cooling characteristics of the spent fuel assembly…
The asymmetric unit of the title salt, (C10H8S8)[Re2Br6(CH3COO)]·0.5C2H3Cl3, contains one bis-(ethyl-enedi-thio)-tetra-thia-fulvalene (ET) radical cation, one μ2-acetato-bis-[tri-bromido-rhenate(III)] anion and a 1,1,2-tri-chloro-ethane mol-ecule with half-occupancy disordered about a twofold rotation axis. The tetra-…
Data supporting "2D Coherent Charge Transport in Highly Ordered Conducting Polymers Doped by Solid State Diffusion" accepted for publication at Nature Materials on 30th March 2016. The data includes raw and processed data from charge transport measurements, spectroscopy (UV-Vis, FTIR, XPS), X-ray diffraction measureme…
Because of the need that exists in the means of generating new studies that serve as a source of information in the welding sector so as to achieve simplify, control or limit the variables involved in a welding process, It is to develop a research type project using an experimental technique for the behavior of a mate…
This paper presents research on the influence of CAM strategies for wear and durability of milling tools. We used two machining principles in this process. In the first instance was constant point of contact with the tool and machining surface. The second method was changing point of the cutting edge in the milling pr…
本文归纳了近些年国内外关于Zr-Sn-Nb—Fe系锆合金第二相方面的一些重要研究结果，总结了Sn，Nb，Fe等合金元素对Zr-Sn-Nb—Fe系锆合金中第二相特征（晶体结构、成分、尺寸、分布等）的影响规律，分析了第二相在加工热处理过程中的析出及演变机制，并指出如何改善第二相类型、尺寸、分布等的一些措施。
Welding processes generally welded joints must comply with the quality requirements established in the standards and requirements of the industry, and this process should ensure high production levels, efficiency and profitability. The GMAW (Gas Metal Arc Welding) in the beginning used only solid wires, but over the y…
The resonance conditions of localized surface plasmon resonances (LSPRs) can be perturbed in any number ways making plasmon nanoresonators viable tools in detection of e.g. phase changes, pH, gasses, and single molecules. Precise measurement via LSPR of molecular concentrations hinge on the ability to confidently coun…
Research on the surface chemistry of quantum dots (QDs) has been rapidly developing in recent years, since the understanding of the processes that occur on their surface is prerequisite for successful exploration of the outstanding fluorescence properties and superior stability of these nanomaterials in numerous appli…
Insulator is a material that cannot or difficult to transfer an electrical charge. Therefore insulator material is used as a barrier between the part that have voltage potential and the part that didn’t have it. Pin-insulator is one kind of insulator, which is used on the straight power- pole (tangent pole) and angle…
Metallic nanoparticles have been used as a way to tailor the fluorescence properties like quantum yield, but regular fluorescence quantum yield measurements have to counter the reflection and dispersion of a sample for an accurate result. Thermal lens spectroscopy is a good alternative to resolve this problem because…
La plupart des pnictures ternaires de formule generale MM'X (ou M et M' sont des metaux de transition et X un element p tel que P et As) cristallisent avec une structure derivee de type Fe2P presentant un effet magnetocalorique (MCE) eleve avec une concentration en electrons d proche de celle de Fe. Au contraire, les…
The technique of the laser controlled deposition of sodium and rubidium deposits on the sapphire substrate is presented. The metals were deposited on the clean sapphire substrate from the vapor phase contained in the evacuated and sealed cell. We use an axicon to produce a non-diffracting Bessel beam out of the beam g…
Abstract The German HTGR fuel development program for the HTR-Modul concept has resulted in a reference design based on LEU UO2 TRISO coated particle fuel in a spherical fuel element. The coated particles consist of minute uranium particle kernels coated with layers of carbon and silicon carbide. Analyses on quality o…
Sir: Kira et al.1 recently published an article about the effectiveness of a bone marrow stromal cell sheet in maintaining random pattern skin flaps. They have cultured bone marrow stromal cell sheets under four different hypoxic conditions and injected the sheets with the highest angiogenic potential into the subcuta…
Abstract In this paper we present the development and characterization of FM/MgO/FM (FM = Co 90 Fe 10 , Fe 20 Ni 80 ) heterostructures. The magnetic order of the structures, magnetic anisotropy and interlayer exchange coupling were characterized by magnetization measurements. The influence of the substrate temperature…
In this paper we show that a 1-D phononic crystal (laminate) can exhibit metamaterial wave phenomenon which is traditionally associated with 2-, and 3-D crystals. Moreover, due to the absence of a length scale in 2 of its dimensions, it can outperform higher dimensional crystals on some measures. This includes allowin…
The back cover picture shows the high-throughput screening (HTS) by NMR approach. Guided by NMR spectroscopy [background picture showing portions of 15N, 1H correlation spectra of the target, in the absence (cyan) and presence (yellow) of a binding ligand], initial weak binders can be identified among mixtures of >100…
We describe the use of UV light under different radiation time induces a variety of fluorescence wavelength of gold quantum clusters. First, we synthesize blue-emitted gold quantum clusters by dissolving the gold trichloride in pure toluene. To simplify the expression, we assume that the several featured PL peak (425,…
