摘要：
CLYC (Ce) crystal is a new type of inorganic scintillator with excellent performance, which can realize neutron and gamma dual mode measurement. CLYC (Ce) detector is widely used in national defense, homeland security, nuclear imaging, environmental monitoring, nuclear medicine and other fields. The detection efficiency of the detector is an important index in the design and development of the detector. The detection model of CLYC (Ce) detector is established by using Geant4 program based on Monte Carlo method, and the factors affecting the detection efficiency of detector are studied. The results show that: the detection efficiency is related to the shape and size of crystal section. The detection efficiency of rectangular section is lower than that of circular and square section, and the larger the crystal radial size and length, the higher the detection efficiency. The detection efficiency of CLYC (Ce) detector is related to the energy of rays: the higher the energy of neutrons and gamma rays are, the lower the detection efficiency is. It indicates that the crystal responds better to thermal neutrons and low-energy gamma rays. At the same time, if the radiation source is emanative, the smaller the distance between the radiation source and the detector, the higher the detection efficiency of the scintillator.

摘要：
Palladium is versatile in many industrial applications due to its distinct physicochemical properties. Due to the scarcity of natural resources and the growing market demand, palladium recovery from wastes such as spent catalysts is receiving increasing attention. Here, a silica-supported thiourea resin (SiPS-TU) was prepared and applied to separate Pd(II) from spent catalysts. The SiPS-TU was fabricated through in situ polymerization and post modification method using amorphous macroporous silica as the matrix. Experimental results suggested that the optimal acidity for the adsorption process was 0.1 M under selected range, and the uptake of SiPS-TU was affected by H+ and Cl-. The adsorbent showed rapid sorption kinetics with an equilibrium attained in 30 min, while more than 3 h was required for the commercial D840 resin. Column tests showed that SiPS-TU had excellent dynamic separation property for Pd(II) in continuous process. Around 215 bed volumes (430 mL) of Pd (II) solution could be effective treated by the SiPS-TU bed before breakthrough at 4 mL/min, while D840 resin bed was less effective under equivalent conditions (20 mL). In view of its satisfactory adsorption performances, palladium was successfully separated from the catalyst leaching solution by SiPS-TU. XPS spectra and DFT calculations indicated that the adsorption mechanism of SiPS-TU for Pd(II) mainly involved anion exchange and coordination. In conclusion, this study provides a feasible material for palladium recovery from practical leachate.
摘要：
This study aims to utilize a hybrid approach of phantom correction and deep learning for synthesized CT (sCT) images generation based on cone-beam CT (CBCT) images for nasopharyngeal carcinoma (NPC). 52 CBCT/CT paired images of NPC patients were used for model training (41), validation (11). Hounsfield Units (HU) of the CBCT images was calibrated by a commercially available CIRS phantom. Then the original CBCT and the corrected CBCT (CBCT_cor) were trained separately with the same cycle generative adversarial network (CycleGAN) to generate SCT1 and SCT2. The mean error and mean absolute error (MAE) were used to quantify the image quality. For validations, the contours and treatment plans in CT images were transferred to original CBCT, CBCT_cor, SCT1 and SCT2 for dosimetric comparison. Dose distribution, dosimetric parameters and 3D gamma passing rate were analyzed. Compared with rigidly registered CT (RCT), the MAE of CBCT, CBCT_cor, SCT1 and SCT2 were 346.11 & PLUSMN; 13.58 HU, 145.95 & PLUSMN; 17.64 HU, 105.62 & PLUSMN; 16.08 HU and 83.51 & PLUSMN; 7.71 HU, respectively. Moreover, the average dosimetric parameter differences for the CBCT_cor, SCT1 and SCT2 were 2.7% & PLUSMN; 1.4%, 1.2% & PLUSMN; 1.0% and 0.6% & PLUSMN; 0.6%, respectively. Using the dose distribution of RCT images as reference, the 3D gamma passing rate of the hybrid method was significantly better than the other methods. The effectiveness of CBCT-based sCT generated using CycleGAN with HU correction for adaptive radiotherapy of nasopharyngeal carcinoma was confirmed. The image quality and dose accuracy of SCT2 were outperform the simple CycleGAN method. This finding has great significance for the clinical application of adaptive radiotherapy for NPC.

摘要：
Environmental radon emanates from the exhalation and release of soil, rocks, and building materials. Environmental radon contamination tracing and radon pollution prevention and control require the measurement of the radon exhalation rate on media surfaces. Reliable measurements of the radon exhalation rate cannot be achieved without regular calibration of the measuring instrument with a high-performance reference device. In this study, a reference device for the calibration of radon exhalation rate measuring instruments was developed using a diffusion solid radon source with a high and stable radon emanation coefficient, an integrated diffusion component composed of a plasterboard and a high-density wooden board, an air pressure balance device, a radon accumulation chamber, and a support structure. The uniformity and stability of the reference device were evaluated using the activated carbon-γ spectrum and open-loop method, respectively, to measure the radon exhalation rate. The reference device achieved different radon exhalation rates by using different activities of diffusion solid radon sources. Nineteen measurement points were regularly selected on the radon exhalation surface of the reference device, and the uniformity of the radon exhalation rate exceeded 5%. The short-term stability of the reference device was better than 5% under different environmental conditions and was almost unaffected by the ambient air pressure, environmental temperature, and relative humidity.

Li/
$$^7$$
Li abundance ratios using Geant4. The neutron-
$$\gamma$$
discrimination performance of the CLLB has been simulated considering different scintillation parameters, physical designs, and light readout modes. A cubic

摘要：
Red mud is a strong alkaline waste from the Bayer process for Al production, which is known as a promising polymetallic secondary resource. The stockpiling and landfill disposal of red mud have produced environmental pollution and resource waste. A novel, promising, environmentally friendly technology for simultaneous extraction of valuable metals from red mud was proposed by ammonium sulfate calcination at temperatures of 250-400? and water leaching. The phase change in the calcination process and various parameters such as the amount of ammonium sulfate, calcination temperature, calcination time, leaching temperature, leaching time and solid-to-liquid ratio on element extraction were investigated. The results indicated that Fe, Cr, Sc and most Al in the red mud were first transformed into (NH4)(3)(Fe, Cr, Sc, Al)(SO4)(3) during the sulfation calcination process and then into NH4(Fe, Cr, Sc, Al)(SO4)(2) at 400 degrees C, while the Al in diaspore was not. More than 98.23% Fe, 70.32% Al, 95.38% Sc and 88.07% Cr were extracted under the optimal conditions, while Ti mainly remained in the leaching residue.
摘要：
Due to its high toxicity, the removal of mercury from groundwater in contaminated industrial areas is of critical importance to avoid health problems for living beings. The functionalization of chitosan with pyrazolinone derivative, allows designing a sorbent (CH-PYZ) with high efficiency and selectivity for mercury sorption at acidic pH values (1.40 mmol Hg g-1, at pH 3). The sorbent is characterized by elemental analysis, thermogravimetric and textural analyses (increase in specific surface area and decrease in pore size), Fourier transform infrared spectroscopy, and shift of the pH point of zero charge toward higher value. The sorption was mainly performed through carbonyl, thiocarbonyl, hydroxyl, and amine groups. Under selected experimental conditions, sorption equilibrium is reached in 40 min (faster than crosslinked chitosan, CH) and the kinetic profile is fitted by the pseudo-first order rate equation. The Langmuir equation finely fits sorption isotherms: the functionalization improves both the maximum sorption capacity and the affinity coefficient (by four to six folds). The benefit of the functionalization is also demonstrated by the improved stability of the sorbent at recycling (loss at the fifth cycle does not exceed 2 % for CH-PYZ, against 8 % for CH). The grafting of pyrazolinone derivative brings another advantage in terms of selectivity against other mono-, di- and tri- valent metal ions. The sorbent also preferentially sorbs mercury from groundwater collected in a contaminated area. Under selected experimental conditions, the sorbent allows decontaminating the collected sample for livestock feeding, but the treated water cannot reach the levels for human drinking water.

摘要：
Herein, the NdFe1−xCoxO3 samples are tested by X‐ray diffraction, scanning electron microscopy, energy‐dispersive X‐ray spectroscopy, and Mössbauer spectra and combined with studying the material's conductivity. The influence of Co doping on the internal production of perovskite and its causes are revealed. At the same time, this article may be the first to test the Mössbauer spectra of NdFe1−xCoxO3 at room temperature (300 K). NdFe1−xCoxO3 samples are prepared by the sol–gel method. The X‐ray diffraction (XRD) results show that these samples conform to the orthogonal perovskite structure (Pbnm), and different doping amounts can cause the patterns to shift by XRD pattern. Through the Williamson–Hall analysis, the microstrain of the lattice between different doping amounts was obtained, and the average crystal size was calculated. The element content of each sample was obtained by scanning electron microscope and energy‐dispersive X‐ray analysis. Mössbauer spectra show that different doping levels change the surrounding environment of iron, and the magnetic properties of the samples also change.
摘要：
Previous simulations studying winds only focus on the line force due to the photons from the central active galactic nucleis (AGNs). What the properties of the winds will be when including the re-radiation force due to the scattered and reprocessed photons (i.e., the re-radiation effect)? We perform simulations to study the large-scale dynamics of accretion disk winds driven by radiation line force and re-radiation force. For the fiducial run, we find that the re-radiation force drives stronger outflows during the early stages. When the flows get into the steadiness, the UV radiation due to spectral lines dominates total radiation and the re-radiation effect could be negligible. The opening angle of winds narrows as initial gas density increases. The larger the gas density is, the stronger the re-radiation effect will be. For $M_{BH}=10^6M_{\odot}$, $\varepsilon=0.3$, the outflows do become much stronger with the re-radiation effect and the winds still can not escape from gravitational potential. We find that the detection probability of ultra-fast outflows (UFOs) and the properties of the winds are both consistent with the observations.

摘要：
In this work, we explore the properties of isospin asymmetric quark matter in quark stars (QSs). The isospin chemical potential, the isospin asymmetry, the quark matter symmetry energy, the equation of state (EOS) of strange quark matter (SQM), and the maximum mass of QSs are also studied by using different quark phenomenological models. Our results indicate that the parameter space of the quark phenomenological models for the quark matter symmetry energy and the EOS of the star matter can be reduced by considering the recent mass-radius estimates of PSR J0740 + 6620, PSR J0030 + 0451, 4U 1702-429, and the central compact star within the supernova remnant HESS J1731-347.

摘要：
Long-term self-irradiation of high-level waste (HLW) matrices may cause diverse microstructural changes, which can degrade their immobilization performance. This study reports the irradiation-induced redox response of Ce-doped pyrochlores, which can be attributed to the damage process in pyrochlores. Lu2Ti2O7 and Lu1.46Ce0.54Ti2O7+x pyrochlores were irradiated by 400 keV Ne2+. The coordinate environment of the elements was characterized by X-ray photoelectron spectroscopy, X-ray diffraction (XRD), and Raman spectroscopy, while the chemical compositions of the samples were analyzed by scanning electron microscopy. First, the irradiation-induced oxidation of Ce was observed in Lu1.46Ce0.54Ti2O7+x at doses of 0–0.052 dpa, and the Ce3+ content was found to decrease from 61.73% to 58.44%. When the dose was increased to 0.261 dpa, the valency of Ce was reduced, and the Ce3+ content increased to 59.25%. Herein, the reduction behavior is discussed in terms of amorphization and recrystallization in the irradiated Lu1.46Ce0.54Ti2O7+x. This irradiation-induced redox behavior of Ce-doped pyrochlores provides another perspective for predicting the long-term performance of HLW matrices in repositories.

摘要：
Although Cs(I) and Sr(II) are not strategic and hazardous metal ions, their recovery from aqueous solutions is of great concern for the nuclear industry. The objective of this work consists of designing a new sorbent for the simultaneous recovery of these metals with selectivity against other metals. The strategy is based on the functionalization of algal/polyethyleneimine hydrogel beads by phosphonation. The materials are characterized by textural, thermo-degradation, FTIR, elemental, titration, and SEM-EDX analyses to confirm the chemical modification. To evaluate the validity of this modification, the sorption of Cs(I) and Sr(II) is compared with pristine support under different operating conditions: the pH effect, kinetics, and isotherms are investigated in mono-component and binary solutions, before investigating the selectivity (against competitor metals) and the possibility to reuse the sorbent. The functionalized sorbent shows a preference for Sr(II), enhanced sorption capacities, a higher stability at recycling, and greater selectivity against alkali, alkaline-earth, and heavy metal ions. Finally, the sorption properties are compared for Cs(I) and Sr(II) removal in a complex solution (seawater sample). The combination of these results confirms the superiority of phosphonated sorbent over pristine support with promising performances to be further evaluated with effluents containing radionuclides.
