摘要 ：
Tungsten (W) is considered the prime candidate for plasma-facing materials (PFMs) in future fusion devices. However, the surface blistering induced by hydrogen isotope irradiation can significantly alter the surface morphology of W, thereby severely impacting its service lifetime. Recent studies have shown that high entropy alloys (HEAs) exhibit excellent radiation resistance. This work focuses on investigating the H+ irradiation effects on low-activity W-based HEAs. A composite target was prepared using a splicing method, and WTaZrCrVTiAl HEA films with an amorphous structure were deposited by magnetron sputtering. Comparative experiments on the HEA film and pure W film under H+ irradiation conditions revealed that the blister dose threshold of the HEA film far exceeds that of the pure W film, which implies that they have more excellent resistance to H+ irradiation.

摘要 ：
Superhydrophobic surfaces have been widely employed in both fundamental research and industrial applications because of their self-cleaning, waterproof, and low-adhesion qualities. Maintaining the stability of the superhydrophobic state and avoiding water infiltration into the microstructure are the basis for realizing these characteristics, while the size, shape, and distribution of the heterogeneous microstructures affect both the static contact angle and the wetting transition mechanism. Here, we review various classical models of wettability, as well as the advanced models for the corrected static contact angle for heterogeneous surfaces, including the general roughness description, fractal theory description, re-entrant geometry description, and contact line description. Subsequently, we emphasize various wetting transition mechanisms on heterogeneous surfaces. The advanced testing strategies to investigate the wetting transition behavior will also be analyzed. In the end, future research priorities on the wetting transition mechanisms of heterogeneous surfaces are highlighted.

摘要 ：
为了制备形貌良好性能优良的硅纳米线,利用金属辅助化学刻蚀法,在AgNO3和HF的混合水溶液中沉积Ag颗粒,使之作为刻蚀反应的催化剂,并在H2 O2和HF的混合溶液中进行刻蚀反应制备硅纳米线.通过改变实验中的工艺参数,包括刻蚀反应时间、刻蚀反应温度、刻蚀液中HF浓度及反应过程中的搅拌速度,用扫描电子显微镜(scanning electron microscope,SEM)图像进行对比分析,讨论制备优良硅纳米线的最佳参数.结果表明:当刻蚀反应时间为1 h,反应温度在室温下,HF浓度为4.8 mol/L时,硅纳米线的表面形貌是最好的,但对刻蚀液的搅拌会严重破坏硅纳米线的表面形貌,不利于优良硅纳米线的制备.

摘要 ：
为剖析城市轨道交通突发事件下乘客出行选择规律,提出基于Logit模型和非线性回归方法的乘客选择影响因素分析方法.首先,从乘客个体属性、出行属性和突发事件属性3个方面确定影响出行选择的主要因素,并进行敏感性分析,在此基础上提出客流浮动率与空间影响系数指标,探索乘客出行选择与时空属性的关系.结果表明:年龄、职业和收入对乘客选择有显著影响,通勤乘客倾向于城市轨道交通出行;乘客选择受事发时间影响明显,而受事发位置或出行距离单一指标影响较小,但空间影响系数对出行选择影响显著.研究可以为突发事件客流预测提供支持,并辅助制定突发客流疏散政策.

摘要 ：
In this study, the method of magnetic Barkhausenn noise (MBN) and tangential magnetic field (TMF) was employed for achieving simultaneous, quantitative prediction of residual stress and surface hardness in box-shape deep drawn parts of SPCC steel. Bi-directional MBN and TMF signals, profiles of surface hardness and residual stress were experimentally measured. Pearson correlation analysis results show that the averaged amplitude of MBN in one magnetization cycle and Root mean square of MBN signal demonstrates approximate linear dependency on residual stress (or surface hardness) in both the measured directions. Three-layer BP models are established after input nodes screening and optimization of neurons' number in the middle hidden layer. BP models are marked corresponding to scanning or magnetization directions. For each direction, two independent models are established and they are combined to use for realizing high accuracy and simultaneous evaluation of the residual stress and surface hardness.

摘要 ：
Partial-denitrification (PD; NO3??NO2?) has recently been proposed to be a feasible choice of NO2?-N supply for anammox bacteria. In this study, an aerobic/anoxic process for treating domestic wastewater was operated for 176 days to evaluate the feasibility of using sludge fermentation liquid for partial denitrification of the wastewater. Results show that, with the ratio of C/N (COD/ NO3?-N) increased at anoxic stage, the average NO2?-N concentration in the effluent and nitrate-to-nitrite transformation ratio (NTR) at anoxic stage showed relative growth. High-throughput sequencing analysis demonstrated that the enhancement of PD can be explained by the increases of Thauera, Paracoccus and Enterobacteriaceae. Moreover, Candidatus_Brocadia (0.13%) was detected as the predominant anammox bacteria. Ex-situ isotopic tracing technique analysis assessed that the ratio of anammox role (ra%) was 7.29%. This study has a great potential for being coupled with the anammox bacteria for advanced nitrogen removal.

摘要 ：
The vertical van der Waals heterostructures based on 2-D materials have attracted tremendous attention in optoelectronic devices as they can offer perfect interface without dangling bonds, atomic layer thicknesses, and conveniently tunable energy band alignment. However, the carrier transport mechanism in vertically stacked van der Waals heterostructure photodetectors is usually neglected in regards of photoresponse enhancement strategy, leading to low photoresponsivity and quantum efficiency. Here, we report a vertically stacked tunneling photodetector based on WSe2/graphene/WS2 van der Waals heterostructure. By introducing graphene film into the WSe2/WS2 interface, the interface composition was ameliorated and the Fowler-Nordheim tunneling (FNT) was enhanced with the reduced tunneling barrier height and thickness, caused by the elevated energy level of electrons since strong electron-electron interaction, ultrafast thermalization (similar to 50 fs), and massless Dirac electrons of graphene. Therefore, the device exhibits a high photocurrent/dark current ratio (>10(4)), fast response time (similar to 300 mu s), high detectivity (similar to 1.58 x 10(12) Jones), and high responsivity (429 mA W-1) across a broad spectral range till 1 mu m at room temperature. The optimized detectivity and responsivity are about 150 times and 50 times higher than WSe2/WS2 device without graphene, respectively. These results contribute to offer a novel and versatile strategy for overcoming the performance limitation in van der Waals photodetector.

摘要 ：
The realization of stable partial nitrification and advanced nitrogen removal are not acquired effectively in conventional pre-denitrification biological nitrogen removal processes treating domestic sewage. Herein, a novel anaerobic/aerobic/anoxic/aerobic (AOAO) continuous plug-flow reactor, characterized with double sludge reflux and a bypass of anaerobic mixed liquor conveyed to anoxic zone, was first constructed to realize stable partial nitrification in treating domestic sewage. The alternating anoxic/aerobic conditions and longer anoxic sludge retention time might be responsible for the partial nitrification. Nitrite accumulation ratio reached 89.3 +/- 3.3% with the maximum activity ratio of AOB to NOB increasing from 0.72 to 8.17. A content total inorganic nitrogen (TIN) removal efficiency (93.7 +/- 2.2%) and effluent TIN concentration (2.9 +/- 0.9 mg N/L) were obtained after 238 days' operation. Specifically, nitrogen balance of the typical cycle showed that about 30.1% of TIN was removed through simultaneous partial nitrification and denitrification (SND) in aerobic zone and 48.2% by endogenous denitrification in anoxic zone. The AOAO process is an economic treatment for domestic sewage with aerobic hydraulic retention time (HRT) of 4 h. (C) 2021 Elsevier B.V. All rights reserved.
