摘要：
Integration of graphene with polymers to construct three-dimensional porous graphene/polymer composites (3DGPCs) has attracted considerable attention in the past few years for both fundamental studies and diverse technological applications. With the broad diversity in molecular structures of graphene and polymers via rich chemical routes, a number of 3DGPCs have been developed with unique structural, electrical, and mechanical properties, chemical tenability, and attractive functions, which greatly expands the research horizon of graphene-based composites. In particular, the properties and functions of the 3DGPCs can be readily tuned by precisely controlling the hierarchical porosity in the 3D graphene architecture as well as the intricate synergistic interactions between graphene and polymers. In this paper, we review the recent progress in 3DGPCs, including their synthetic strategies and potential applications in environmental protection, energy storage, sensors, and conducting composites. Lastly, we will conclude with a brief perspective on the challenges and future opportunities.

摘要：
The present study investigated the biosorption capacity of live and dead cells of Bacillus cereus RC-1 for Cd(II). The biosorption characteristics were investigated as a function of initial pH, contact time, and initial cadmium concentration. Equilibrium biosorption was modeled using Langmuir, Freundlich and Redlich-Peterson isotherm equations. It was found that the maximum biosorption capacities calculated from Langmuir isotherm were 31.95 mg/g and 24.01 mg/g for dead cells and live cells, respectively. The kinetics of the biosorption was better described by pseudo-second order kinetic model. Desorption efficiency of biosorbents was investigated at various pH values. These results indicated that dead cells have higher Cd(II) biosorption capacity than live cells. Furthermore, zeta potential, transmission electron microscopy (TEM), scanning electron microscopy (SEM) coupled with energy dispersive X-ray (EDX), and Fourier transform infrared spectroscopy (FTIR) studies were carried out to understand the differences in the Cd(II) biosorption behavior for the both biosorbents. The bioaccumulation of Cd(II) by B. cereus RC-1 was found to depend largely on extracellular biosorption rather than intracellular accumulation. Based on the above studies, dead biomass appears to be a more efficient biosorbent for the removal of Cd(11) from aqueous solution. (C) 2013 Elsevier B.V. All rights reserved.

摘要：
This work concerns directly the extraction of gadolinium from Gd <inf>2</inf>O<inf>3</inf>by co-reduction with Al<sup>3+</sup>in theLiCl-KCl-AlCl<inf>3</inf>molten salts on the molybdenum and aluminum electrode, respectively, at temperatureof 773 K. Gibbs energy calculation shows that AlCl<inf>3</inf> can favorably chloridize Gd<inf>2</inf>O<inf>3</inf>and release Gd<sup>3+</sup>ions. The electrochemical behaviors of Al<sup>3+</sup>, Gd<sup>3+</sup> and the mechanisms of alloy formation were investi-gated by conducting a series of electrochemical techniques. Four typical signals were observed in cyclicvoltammetry, square wave voltammetry and chronopotentiometry, while five plateaus were observedin open circuit chronopotentiometry, which might correspond to different kinds of Gd-Al intermetalliccompounds. Potentiostatic and galvanostatic electrolysis were conducted to extract gadolinium from theLiCl-KCl-AlCl3melts by the co-reduction method, and it was found that if the molybdenum cathode wasused, GdAl<inf>2</inf> particles would be deposited and adhere to a large amount of salt electrolytes. In contrast,when the aluminum plate was used as the cathode, a layer formed by potentiostatic electrolysis cor-responding to an intermetallic compound (GdAl<inf>3</inf>) and three layers formed by galvanostatic electrolysiscorresponding to three different Gd-Al intermetallic compounds such as GdAl<inf>3</inf>, GdAl <inf>2</inf> and GdAl couldbe collected and identified through scanning electron microscopy (SEM)-energy dispersive X-ray (EDX)and X-ray diffraction (XRD) analysis. Besides, electroextractions of gadolinium by co-reduction with Al <sup>3+</sup> on the aluminum electrode have been performed with extraction efficiency of 89.7% for potentiostaticelectrolysis and 96.5% for galvanostatic electrolysis, respectively. ©2013 The Authors.

摘要：
The behaviors of monolayer graphene sheet have attracted increasing attention of many scientists and researchers. In this study, the propagation behaviors of in-plane wave in viscoelastic monolayer graphene are investigated. The constitutive equation and governing equation for in-plane wave propagation is developed by employing Hamilton’s principle and nonlocal strain gradient theory. By solving the governing equation of motion, the closed-form dispersion relation between phase velocity and wave number is derived and an asymptotic phase velocity can be acquired. The effects of wave number, material length scale parameter, nonlocal parameter and damping coefficient on in-plane wave propagation behaviors are discussed in the numerical studies. It is found that, when exciting wavelengths or structural dimensions become comparable to the material length scale parameters and nonlocal parameters, the scaling effects on wave propagation behaviors are significant. For nanoscaled graphene sheet, the effects of nonlocal parameter, material length scale parameter and damping coefficient on phase velocity are tiny at low wave numbers while significant at high wave numbers. The phase velocity would increase with the increase of material length scale parameter or the decrease of nonlocal parameter and damping coefficient. Furthermore, results indicate that the asymptotic phase velocity can be increase by increasing material length scale parameter or decreasing nonlocal parameter. ©2017, Springer-Verlag Berlin Heidelberg.

摘要：
In this work, a facile method was adopted to synthesize molybdenum disulfide/reduced graphene oxide (MoS_2/rGO) composites through an L-cysteine-assisted hydrothermal technique. The as-prepared MoS_2/ rGO composites were firstly applied as adsorbents for efficient elimination of Pb(II) ions. Batch adsorption experiments showed that the adsorption of Pb(II) on MoS_2/rGO followed pseudo-second-order kinetic model well. The adsorption of Pb(II) was intensely pH-dependent, ionic strength-dependent at pH < 9.0 and ionic strength-independent at pH > 9.0. The presence of humic acid (HA) enhanced Pb(II) adsorption obviously. The MoS_2/rGO composites exhibited excellent adsorption capacity of 384.16 mg g~(-1) at pH 5.0 and T=298.15 K, which was superior to MoS_2 (279.93 mg g~(-1)) and many other adsorbents. The thermodynamic parameters suggested that the adsorption process of Pb(II) on MoS_2/rGO composites was spontaneous (?G~θ < 0) and endothermic (?H~θ > 0). The interaction of Pb(II) and MoS_2/ rGO was mainly dominated by electrostatic attraction and surface complexation between Pb(II) and oxygen-containing functional groups of MoS_2/rGO. This work highlighted the application of MoS_2/rGO as novel and promising materials in the efficient elimination of Pb(II) from contaminated water and industrial effluents in environmental pollution management.

摘要：
Situation awareness (SA) is a key element that impacts operator's decision-making and performance in nuclear power plants (NPPs). The subsequent complex cognitive activities cannot be correctly completed due to errors of situation awareness (ESA), which will lead to disastrous consequences. In order to investigate and analyze operator's ESA in the digitized main control room (DMCR) of a nuclear power plant, the model of ESA is established, the classification system of ESA is developed based on the built ESA model, and the analysis method of ESA is also constructed on the basis of the observation of simulator and operator surveys. Finally, a case study is provided to illustrate the concrete application of the method. It provides a theoretical and practical support for the operator's SAE analysis in a digitized main control room of a nuclear power plant. (C) 2016 Elsevier Ltd. All rights reserved.

摘要：
We use quantum electrodynamics (QED) particle-in-cell simulations to investigate and compare the generation of dense electron-positron plasmas and intense γ-ray bursts in the case of counter-propagating laser solid interaction (two-side irradiation) and single laser solid interaction (one-side irradiation). In the case of counter-propagating linearly polarized laser pulses irradiating a thin aluminum foil with each pulse peak power of 12.5 PW (I=4×10<sup>23</sup>W/cm<sup>2</sup>), we calculate that about 20% of the laser energy is converted into a burst of γ-rays with flux exceeding 10<sup>14</sup>s.<sup>-1</sup>This would be one of the most intense γ-ray sources among those currently available in laboratories. The γ-ray conversion efficiency in the case of two-side irradiation is three times higher than in the case of one-side irradiation using a single 12.5 PW laser. Dense electron-positron plasma with a maximum density of 6×10<sup>27</sup>m<sup>-3</sup>are generated simultaneously during the two-side irradiation which is eightfold denser compared to the one-side irradiation. The enhancement of the effects in the case of counter-propagating lasers are the results of the symmetrical compression of the foil target and the formation of electric potential and standing wave around the target. Realizing experimentally the proposed counter-propagating QED-strong laser-solid interaction to produce dense electron-positron pairs and prolific γ-rays will be made possible by the Extreme Light Infrastructure-Nuclear Physics facility under construction. ©2015 AIP Publishing LLC.

摘要：
In this work, the electrochemical behaviors of Dy(III) and its co-reduction with Al(III) on an inert tungsten electrode was investigated in LiCl-KCl molten salts at the temperature of 773 K by using cyclic voltammetry (CV), chronopotentiometry (CP) and square wave voltammetry (SWV) techniques. The results showed that the reduction of Dy(III) ions in LiCl-KCl salts is a reversible diffusion controlled process through a one-step reaction: Dy(III) + 3e<sup>-</sup> ?Dy(0). The diffusion coefficient of Dy(III) ions was calculated by both the CV and CP methods. Furthermore, the co-reduction of Al(III) and Dy(III) ions on the inert tungsten electrode allows Dy(III) ions to be reduced at a more positive potential through forming Al-Dy alloys. The concentration ratio of Al(III) cations to Dy(III) cations has a large impact on the formation of Al-Dy alloys. In a Dy(III) ion rich system, three signals attributed to the formation of Al-Dy intermetallic compounds were observed in CV and SWV analyses, while only two signals corresponding to Al-Dy intermetallic compounds were observed in the Dy(III) ion poor system. Potentiostatic and galvanostatic electrolyses performed on an aluminum electrode identified the co-reduction by the formation of one (Al<inf>3</inf>Dy) and two Al-Dy alloys (Al<inf>3</inf>Dy, AlDy), respectively. Finally, the electrolysis products were characterized by the Scanning Electron Microscopy (SEM) coupled with Energy Dispersive Spectroscopy (EDS) and X-ray diffraction (XRD) analyses. ©2014 Elsevier Ltd.

摘要：
This work firstly presents an electrochemical study of samarium extraction from Sm<inf>2</inf>O<inf>3</inf> in the LiCl-KCl-AlCl<inf>3</inf> melts. Gibbs energy calculation shows that AlCl<inf>3</inf> can favorably chloridize Sm <inf>2</inf>O<inf>3</inf> and release Sm<sup>3+</sup> ions under this condition. The electrochemical behaviors of Al<sup>3+</sup>, Sm<sup>3+</sup> and the mechanisms of alloy formation were investigated using a series of electrochemical techniques on a molybdenum electrode. Two typical signals corresponding to different kinds of Sm-Al alloys were observed in the cyclic voltammetry and square wave voltammetry. The transformation process from one Al<inf>x</inf>Sm<inf>y</inf> biphasic phase to another was revealed by open circuit chronopotentiometry. The Sm-Al alloy samples were prepared by potentiostatic and galvanostatic electrolysis on an aluminium electrode. SEM-EDS and XRD analysis demonstrated that a layer of SmAl<inf>3</inf> can be formed by potentiostatic electrolyses, whereas two kinds of intermetallic compounds of SmAl<inf>4</inf> and SmAl<inf>3</inf> can be formed by galvanostatic electrolysis. In addition, the electroextraction of samarium by co-reduction with Al<sup>3+</sup> on the aluminium electrode has been performed with extraction efficiency of 88.7% for potentiostatic electrolysis and 94% for galvanostatic electrolysis, respectively. ©2014 Elsevier Ltd.

摘要：
This work concerns the electrochemical behaviors of Th<sup>4+</sup> on the tungsten, aluminum and bismuth electrodes in the LiCl-KCl eutectic, respectively, at 773 K. Cyclic voltammetry and square wave voltammetry were employed to investigate the cathodic reduction of Th<sup>4+</sup>. The results demonstrate that the reduction of Th<sup>4+</sup> is a one step process with a transfer of 4 electrons. The reversibility of the Th<sup>4+</sup>/Th couple on the bismuth film and tungsten electrodes is directly confirmed by the CV. The diffusion coefficient is also calculated to be (2.23 ±0.16) ×10<sup>-5</sup> and (7.19 ±0.12) ×10<sup>-5</sup> cm <sup>2</sup>/s by applying both cyclic voltammetry and chronopotentiometry, respectively. A series of redox couples were confirmed to be associated with the formation of different kinds of Al-Th intermetallic compounds. Compared to Al electrode, a cathodic shift of the reduction potential of the Th<sup>4+</sup> is observed on the Al film electrode which is not conducive for the potentiostatic extraction of thorium. The cathodic depolarization gives a shift of 420 mV on the Al electrode, while 490 mV on the Bi film electrode for the reduction of Th<sup>4+</sup> compared to the inert W electrode. The reduction potential of Th<sup>4+</sup> on the Bi film electrode is 70 mV more anodic than that on the Al electrode. Potentiostatic electrolyses were carried out on an Al plate and Bi liquid electrode to confirm the formation of the Th alloys. Two Al-Th alloys (Al<inf>3</inf>Th and Al<inf>2</inf>Th) and one Bi-Th alloy (Bi<inf>2</inf>Th) were obtained, respectively. ©2014 Published by Elsevier Ltd.

摘要：
Based on the finite-difference time-domain method, we investigate the transmission resonances of compound metallic gratings with two subwavelength slits filled with different dielectrics inside each period in the visible and near infrared regions. The results show that the transmission spectrum is almost a compound of that of two corresponding simple gratings expect for the transmission feature at a certain resonant wavelength, where the Fabry-Pe´rot (FP)-like phenomena have been found both inside the two slits, but the orders of the FP-like modes are different. If the order of the FP-like mode inside one slit is one bigger than inside the other, the intensity of the transmission will be significantly weakened. We attribute this phenomenon to the phase resonance because the phases at the exits of the two slits are opposite to each other. ©2011 Optical Society of America.

摘要：
Accurate superficial dose calculation is of major importance because of the skin toxicity in radiotherapy, especially within the initial 2 mm depth being considered more clinically relevant. The aim of this study is to evaluate superficial dose calculation accuracy of four commonly used algorithms in commercially available treatment planning systems (TPS) by Monte Carlo (MC) simulation and film measurements. The superficial dose in a simple geometrical phantom with size of 30 cm×30 cm×30 cm was calculated by PBC (Pencil Beam Convolution), AAA (Analytical Anisotropic Algorithm), AXB (Acuros XB) in Eclipse system and CCC (Collapsed Cone Convolution) in Raystation system under the conditions of source to surface distance (SSD) of 100 cm and field size (FS) of 10×10 cm<sup>2</sup>. EGSnrc (BEAMnrc/DOSXYZnrc) program was performed to simulate the central axis dose distribution of Varian Trilogy accelerator, combined with measurements of superficial dose distribution by an extrapolation method of multilayer radiochromic films, to estimate the dose calculation accuracy of four algorithms in the superficial region which was recommended in detail by the ICRU (International Commission on Radiation Units and Measurement) and the ICRP (International Commission on Radiological Protection). In superficial region, good agreement was achieved between MC simulation and film extrapolation method, with the mean differences less than 1%, 2% and 5% for 0°, 30°and 60°, respectively. The relative skin dose errors were 0.84%, 1.88% and 3.90%;the mean dose discrepancies (0°, 30°and 60°) between each of four algorithms and MC simulation were (2.41±1.55%, 3.11±2.40%, and 1.53±1.05%), (3.09±3.00%, 3.10±3.01%, and 3.77±3.59%), (3.16±1.50%, 8.70±2.84%, and 18.20±4.10%) and (14.45±4.66%, 10.74±4.54%, and 3.34±3.26%) for AXB, CCC, AAA and PBC respectively. Monte Carlo simulation verified the feasibility of the superficial dose measurements by multilayer Gafchromic films. And the rank of superficial dose calculation accuracy of four algorithms was AXB>CCC>AAA>PBC. Care should be taken when using the AAA and PBC algorithms in the superficial dose calculation. ©2016 Elsevier Ltd

摘要：
The capabilities of current drive, neoclassical tearing mode (NTM) stabilization, and sawtooth control are analyzed for the electron–cyclotron wave (ECW) system in a HL-2M tokamak. Better performance of the upper launcher is demonstrated in comparison with that of a dropped upper launcher, in terms of J_(EC)/J_(bs) for NTM stabilization and I_(ECCD)/(?_ρ(tor))~2 for sawtooth control. 1-MW ECW power is enough for the 3/2 NTM stabilization, and 1.8-MW ECW power is required to suppress 2/1 NTM in a single null divertor equilibrium with 1.2-MA toroidal current with the upper launcher. Optimization simulation of electron–cyclotron current drive (ECCD) is carried out for three mirrors in an equatorial port, indicating that the middle mirror has a good performance compared with the top and bottom mirrors. The results for balanced co-and counter-ECCD in an equatorial port are also presented.

摘要：
This work presents an electrochemical study of Er<sup>3+</sup> and Al <sup>3+</sup> in the LiCl-KCl-AlCl<inf>3</inf>-Er<inf>2</inf>O<inf>3</inf> melts at 773 K. Gibbs energy calculation shows that AlCl<inf>3</inf> can favorably chloridize Er<inf>2</inf>O<inf>3</inf> and release Er<sup>3+</sup> ions under this condition. Cyclic voltammetry, square wave voltammetry, chronopotentiometry and open-circuit chronopotentiometry were applied using a molybdenum electrode to investigate the reduction behavior of Er<sup>3+</sup> and Al<sup>3+</sup> and to identify the Er-Al alloys. A series of redox signals corresponding to different kinds of Er-Al alloys were revealed. Potentiostatic and gavanostastic electrolysis were both conducted on an aluminium electrode to prepare the Er-Al alloys. The obtained deposits were charaterized by SEM-EDS and XRD. A layer of ErAl<inf>3</inf> was obtained by potentiostatic electrolysis, whereas two kinds of intermetallic compounds of ErAl<inf>3</inf> and ErAl<inf>2</inf> were formed by galvanostatic electrolysis. ©2013 Elsevier Ltd.

摘要：
It is demonstrated that bright femtosecond X-rays can be obtained by irradiating a moderate laser onto a helium micro-droplet. The laser ponderomotive force continuously sweeps electrons from the droplets and accelerates them forward. The electrons exposed in the outrunning laser field oscillate transversely and emit photons in the forward direction. The total flux of photons with energies above 1keV is as high as 10<sup>9</sup>/shot which is about 10-fold enhancement compared with betatron oscillation under similar laser conditions. The maximum achieved peak brightness is up to 10<sup>21</sup>photons/s/mm<sup>2</sup>/mrad<sup>2</sup>/0.1%BW. By adjusting laser and droplet parameters, we can get tunable X-rays with required brightness and energy. ©2014 AIP Publishing LLC.

摘要：
In nuclear power plants (NPPs), man-machine interfaces (MMIs) are being transformed from conventional panels to computer workstations. Therefore, operators' behavior and performance shaping factors (PSFs) in modern main control rooms (MCRs) differs from what they do in a conventional one. New human error, error mechanism and PSFs etc. are introduced into digital control systems (DCS). The conventional human error analysis (HEA) methods cannot meet new requirements. So it is important to establish a new technique of HEA for investigating human failure events in digital NPPs. In order to investigate and analyze human errors and to trace organizational root causes in digital NPPs, an Organization oriented Technique of Human Error Analysis (OTHEA) was established. At this first paper, an organization-oriented conceptual model of HEA was established. Furthermore, the classification framework of HEA was developed based on the established conceptual model of HEA, including classification of human error, PSFs, psychological error mechanisms (PEMs), error recovery failures (ERFs) and safety barriers. It provides a theoretical guidance and practical support for the investigation of human failure events in digital NPPs. (C) 2018 Elsevier Ltd. All rights reserved.

摘要：
Silicon carbide fiber-reinforced silicon carbide matrix composites have been investigated for their use as structural materials for advanced nuclear reactor. Although quite a number of researches have been devoted to probe the effects of irradiation on various properties of the composites, there is little known about the atomistic mechanism for irradiation resistance. In this study, a two-temperature model has been used to investigate the irradiation damage of SiC/Gra/SiC composites, which includes three parts and two SiC/C interfaces, two single crystal cubic silicon carbide on two sides and a few graphene sheets in the middle part. By simulating 100 keV displacement cascades, we find that the number of defects in the reinforcement is larger than that in the matrix, which indicates the damage in the reinforcement is more serious than that in the matrix. Moreover, we explicitly investigate the damage behavior of the interphase graphene layers and find that some atoms in one graphene sheet form many new chemical bonds with atoms in another one, which leads to the transition from sp<sup>2</sup>to sp<sup>3</sup>hybridization. The newly formed chemical bonds link the different graphene layers and make graphene-like electronic structure more “diamond-like”, enhancing the irradiation resistance of the matrix. ©2017 Elsevier B.V.

摘要：
A shashlik-type electromagnetic calorimeter will be produced in Hall A of Jefferson Laboratory for the Solenoidal Large Intensity Device (SoLID). Wavelength-shifting (WLS) fibers and clear fibers will be used as the light guide part of the calorimeter. The blue light from scintillators is converted into green light by WLS fibers and is carried out to the back of the calorimeters for readout. Since the magnetic field of SoLID reaches about 1.5 T behind the calorimeters, the design is to use clear fibers to further guide the light out of the solenoid for readout by PMTs. Therefore, it is important to study the perfomance of WLS and clear fibers. This paper describes a comparative test of two different WLS fibers and a light attenuation test for a clear fiber. The results show that the performance of the two WLS fibers is the same under large curvature bending, and that the bending has no effect on the light transmission through the clear fiber. In addition, a comparison test for two fiber end-face reflective materials is also reported. It reveals that the use of silver ink as a reflective material can increase the light yield by 30%. Thereby, an optimized prototype based on the above experimental results was built and the basic performance was tested.

摘要：
A plasmonic splitter based on subwavelength metal-insulator-metal (MIM) waveguides with tooth-shaped structures is proposed and numerically researched by using the finite-difference time-domain (FDTD) method in visible and near infrared frequencies. The splitter is regarded as two zigzag-shaped MIM waveguides, which naturally stretch out two tooth structures in bending corners. Each tooth forms a resonant cavity. The transmission of the zigzag-shaped waveguide is close to zero at some resonant wavelength of the tooth cavity. The same-order resonant wavelength has an approximately linear relationship with the depth of the tooth. When the geometric parameters of the two zigzag-shaped waveguides of teeth are suitably initialized, both frequency splitter and power splitter can be simply achieved. ©2014 ©2014 Taylor &Francis.

摘要：
A numerical simulation of the energy deposition distribution in semiconductors is performed for <sup>63</sup>Ni beta particles. Results show that the energy deposition distribution exhibits an approximate exponential decay law. A simple theoretical model is developed for <sup>63</sup>Ni betavoltaic battery based on the distribution characteristics. The correctness of the model is validated by two literature experiments. Results show that the theoretical short-circuit current agrees well with the experimental results, and the open-circuit voltage deviates from the experimental results in terms of the influence of the PN junction defects and the simplification of the source. The theoretical model can be applied to <sup>63</sup>Ni and <sup>147</sup>Pm betavoltaic batteries. ©2013 Elsevier Ltd.
