232Th/233U fuel cycle is an alternate candidate for future nuclear energy. Neutron-induced fission cross section of 232Th one the important data if using thorium as in future. 232Th(n, f) sections from 1 to 300 MeV were measured at China Spallation Neutron Source (CSNS) Back-streaming neutron facility (Back-n) relative 235U(n, and n-p scattering. A fast ionization chamber measurement (FIXM) a proton recoil telescope (PRT) used perform measurement. The energy this reaches up which supposed be...
Geopolymer gel that possesses advantageous features of fast setting, high strength, and good durability is increasingly used in civil engineering, including rapid retrofit projects, roadway, other construction projects. Furthermore, geopolymer also a green economical material as it derives from solid wastes. In this study, activators with different sodium silicate modulus alkali content were to activate ultrafine coal gangue slag powder prepare coal-gangue-based geopolymers strength. To...
Geopolymer is a green non-metallic material with high strength and favorable properties in resistance to corrosion, fire, temperature, which makes it potential substitute for Portland cement. The existing studies have primarily focused on the preparation of geopolymers using silico-alumina materials such as fly ash, red mud, metakaolin, volcanic blast furnace slag develop geopolymers. This study explores ultrafine calcined coal gangue ground granulated new geopolymer activation single...
The as-quenched structure of Zr80Pt20 melt-spun ribbons containing measured oxygen contents ranging from 184 to 4737 ppm mass was studied. Ribbons less than 500 are fully crystallized and consist predominantly a metastable ordered β-Zr phase with significant solution Pt. Increasing content 1053 1547 produces transition amorphous mixed quasicrystalline structures, respectively. Samples crystalline phases in an matrix. results this study suggest critical level is required promote glass...
Coal gangue, a solid waste produced in coal production, had caused serious environmental pollution due to accumulation on dumps. Embankment filling can solve the problem while significantly consuming amount of for mining. The main purpose this study is investigate mechanical properties and microscopic structure gangue when it subjected erosion from water environment with different acidity. Using immersion testing evaluate its stability hydro-chemical environments. Mechanical property...
Abstract Dynamic rheology, differential scanning calorimetry and in situ Fourier transform infrared spectroscopy were used to study the cure behavior of unsaturated polyester/modified montmorillonite nanocomposites. The results showed that their gel times increased markedly at same temperature, activation energy nanocomposites was higher than pure polyester. Their peak temperatures enthalpy as well. total exotherm reaction declined rate decreased. In curing process polyesters, conversion...
Abstract The Back-n white neutron source (known as Back-n) is based on back-streaming neutrons from the spallation target at China Spallation Neutron Source (CSNS). With its excellent beam properties, e.g., a flux of approximately 1.8×10 7 n/cm 2 /s 55 m target, energy range spanning 0.5 eV to 200 MeV, and time-of-flight resolution few per thousand, along with equipped physical spectrometers, considered be among best facilities in world for carrying out nuclear data measurements. Since...

Furthermore, using scanning electron microscope, energy dispersive system, Raman spectrometer analyze microscopic mechanism view microstructure, elements, integrity carbon structure stability...
Previous rapid solidification studies of Zr–Pt alloys have focused primarily on compositions very close to the Zr80Pt20 eutectic. In current work, a wide range alloys, Zr x Pt100 − (69 ≤ 81), were synthesized by melt spinning examine their starting structures and devitrification behaviours. Similar frequently reported formation metastable quasicrystalline phase during heating near-eutectic compositions, ribbons with contents as low 75 at.% show comparable transformations, but at higher...
Different from the glassy Zr62Ti7.07Nb2.21Cu12.28Ni9.81Al6.62 melt-spun ribbon that forms a quasicrystalline phase upon devitrification, corresponding alloy produced by mechanical alloying of elemental powder mixtures does not clearly show quasicrystal formation. However, addition an appropriate amount zirconium to mechanically alloyed changes crystallization behavior inducing formation icosahedral as first product. This indicates for this multicomponent metallic glass in is crucially linked...
A 4-π detector array composed of 40 BaF_2 crystals named Gamma Total Absorption Facility II (GTAF-II) is designed for neutron capture cross-section (n, γ) measurements at Back-n white source in China Spallation Neutron Source. The waveform digitizing (WFD) method used to acquire the signals from GTAF-II accurately. To reduce high data rate caused by WFD method, a real-time digital trigger system proposed this paper. divided into local and global processing distinguish desired various noises....
Coal gangue-slag geopolymer is a kind of environment-friendly material with excellent engineering performance and formed from coal gangue slag after excitation by an alkaline activator. In this study, three kinds were activated different activators, the compressive flexural strengths water sulphate solutions in wetting-drying (W-D) cycles compared.
