Abstract ：
W-Re alloys are one of the most important refractory materials with excellent high-temperature performance that were developed to improve the brittleness of tungsten. In the present work, we firstly summarized the research progress on the preparation and strengthening methods of a W-Re alloy. Then, the strengthening mechanisms of the W-Re alloy were discussed, including the influence of Re, solid solution strengthening, second-phase reinforcement and fine-grain strengthening. The results showed that the softening effect of Re was mainly related to the transformation of the preferred slip plane and the introduction of additional d-valence electrons. Some transition elements and refractory metal elements effectively strengthened the W-Re alloy. Carbides can significantly enhance the high-temperature mechanical properties of W-Re alloys, and the reasons are twofold: one is the interaction between carbides and dislocations, and the other is the synergistic strengthening effect between carbides and Re. The objective of this work was to enhance the comprehension on W-Re alloys and provide future research directions for W-Re alloys.

Abstract ：
采用固–液混合法制备出不同锇（Os）含量（原子数分数）的亚微米级钨锇混合粉体，通过微波烧结获得了孔道结构均匀的钨锇混合基扩散型阴极。电子发射测试结果表明，元素Os的加入使浸渍型钨基阴极的发射性能有明显提高。对比不同锇含量的混合基阴极，发现W-25Os阴极（Os原子数分数为25%）具有相对较低的逸出功和较高的发射电流密度，其在1100℃时脉冲发射电流密度为42.86 A·cm~(-2)，斜率为1.40，发射电流密度是同等工作条件下传统钡钨阴极的1.7倍，达到了覆膜M型阴极的电子发射水平。W-25Os混合基阴极的有效逸出功最低为1.93 eV，有利于活性自由钡（Ba）的生成，表层元素摩尔比Ba:(W+Os)为0.83:1.00，比传统钡钨阴极中Ba:W（约为0.50:1.00）摩尔比有了明显提高。

目前,开发绿色高效的重金属吸附材料受到人们的广泛关注.以硅藻土为原料,经水热法选择性地制备了2类硅酸盐材料即麦羟基硅钠石和方沸石.吸附测试结果表明,麦羟基硅钠石层间的钠离子能够与锂离子、镁离子、锌离子、钴离子、镍离子、铜离子等进行阳离子交换且能保持层状母体框架的稳定性.以钴离子、镍离子为例深入研究其吸附动力学和吸附机制发现,钴离子和镍离子的嵌入分别将麦羟基硅钠石的层间距由本征的1.56 nm减小到0.24、0.23 nm;室温下,对钴离子、镍离子的最大吸附量分别可达45、39 mg/g,均符合Langmuir单层吸附模型;钠离子的置换量大约是吸附的钴离子、镍离子量的两倍,证实层间离子交换主导吸附化学过程.因此,麦羟基硅钠石材料在多金属硅酸盐功能材料的合成以及环境吸附净化领域具有较大的应用潜力.

Abstract ：
Tetracycline (TC) and arsenic contaminants are two main pollutants in aquaculture and livestock husbandry, and they have drawn worldwide attention. To address this issue, a novel N-doped carbon@magnesium silicate (CMS) was fabricated via a facile and low-cost hydrothermal route, adopting glucose and ammonia as C and N sources, respectively. The synergetic combination of carbon and magnesium silicate makes CMS possess a high surface area of 201 m(2)/g and abundant functional groups. Due to the abundant C- and N-containing functional groups and Mg-containing adsorptive sites, the maximum adsorption capacity values of CMS towards As(V) and TC are 498.75 mg/g and 1228.5 mg/g, respectively. The type of adsorption of As(V) and TC onto CMS is monolayer adsorption. An adsorption kinetic study revealed that the mass transfer and intraparticle process dominates the sorption rate of As(V) and TC adsorption onto CMS, respectively. Various functional groups synthetically participate in the adsorption process through complexion, & pi;-& pi; EDA interactions, and hydrogen bonds. This work provides a one-step, low-cost route to fabricate a N-doped carbonaceous adsorbent with a high surface area and abundant functional groups, which has great potential in the application of practical sewage treatment.

Abstract ：
The strong electrostatic interaction between high-charge-density zinc ions (112 C mm(-3)) and the fixed crystallinity of traditional oxide cathodes with delayed charge compensation hinders the development of high-performance aqueous zinc-ion batteries (AZIBs). Herein, to intrinsically promote electron transfer efficiency and improve lattice tolerance, a revolutionary family of high-entropy oxides (HEOs) materials with multipath electron transfer and remarkable structural stability as cathodes for AZIBs is proposed. Benefiting from the unique "cock-tail" effect, the interaction of diverse type metal-atoms in HEOs achieves essentially broadened d-band and lower degeneracy than monometallic oxides, which contribute to convenient electron transfer and one of the best rate-performances (136.2 mAh g(-1) at 10.0 A g(-1)) in AZIBs. In addition, the intense lattice strain field of HEOs is highly tolerant to the electrostatic repulsion of high-charge-density Zn2+, leading to the outstanding cycling stability in AZIBs. Moreover, the super selectability of elements in HEOs exhibits significant potential for AZIBs.

Abstract ：
In this study Zn doping was applied to MgO thin films in order to improve the secondary electron emission (SEE) property via relieving the surface charging and modifying the electron structure of MgO. MgO and Mg1-xZnxO thin films (the Zn doping proportion x is within 11 at.%) were prepared on Si substrates by a simple, cost effective aerosol assisted chemical vapor deposition method followed by annealing at elevated temperature. The surface morphology and microstructure of the Mg1-xZnxO films were characterized. Secondary electron yield (o) as a function of primary electron energy the films was examined. First principles calculation based on the density functional theory was introduced to evaluate the electronic structure and work function of Mg1-xZnxO crystals. SEE testing results revealed that o of the MgO film is effectively improved by Zn doping of proper concentration. The undoped MgO film with relatively smooth surface exhibits a maximum secondary electron yield (om) of 5.1 at Ep of 750 eV. The om of the Mg1-xZnxO film (x = 0.09) is 7.0 at Ep = 1500 eV, which is 34.6% higher than that of the MgO film prepared under identical method. Improvement of o of the Mg1-xZnxO films with x < 0.1 is probably due to the unique surface morphology with protrusions and sharp edges and the increase of electrical conductivities of the films. Another factor contributing to the o increase is the decrease of work function due to Zn doping, which is confirmed by first-principles calculation of Mg1-xZnxO crystals.

Abstract ：
Heavy metal pollution has caused worldwide attention due to its toxicity to people's health. It's necessary to design and synthesize adsorbents with excellent adsorption performance in low cost. In this work, diatomite is adopted as a self-sacrificing template for the synthesis of adsorbent Mg-chlorite. The three-dimensional (3D) hierarchical porous Mg-chlorite perfectly inherits structure characters from diatomite and exhibits a high specific surface area of 337 m(2)/g. The maximum adsorption capacities of Mg-chlorite towards Pb(II) and Cd(II) reach 961 mg/g and 506 mg/g, respectively, higher than that of the referenced adsorbents. The Pb(II), Cd(II) adsorption onto Mg-chlorite is a monolayer exothermic process. Chemisorption mainly controls the adsorption rate, in which mass transfer exerts greater influence than intra-particle-diffusion. Electrostatic attraction, chemisorption and co-precipitation are involved in the adsorption process, and co-precipitation mainly contributes to the excellent adsorption performance according to XRD, FT-IR and XPS analysis. This study provides a novel diatomite-template self-sacrificing method in the synthesis of 3D hierarchical porous magnesium silicate. The excellent adsorption performance for Pb(II) and Cd(II) species makes the low cost Mg-chlorite a great potential in the application of practical environment remediation.

Abstract ：
In this work, a strategy of heat treatment-precipitation has been developed to recycle Ti-containing metallurgical solid waste by forming Ti-embedded MgAl layered double hydroxide (TMA-LDH). This facile and simple route is featured by the dedicated utilization of the composition of slag with high overall recovery efficiency. Importantly, as-obtained product exhibits visible light response distinctly different from that of pristine MA-LDH ascribed to the Fe doping inherited from initial slag. Its mesoporous nanostructure also provides more microchannels for mass and carrier transfer. As such, excellent photocatalytic activity towards degradation of tetracycline hydrochloride is achieved, and 88% removal could be obtained in 60 min. Furthermore, 44% increase in efficiency than that of Ti-excluded LDH also indicates the synergistically promoting effect of Ti incorporation. Mechanism investigation suggests that Ti incorporation regulates the electronic structure of pristine LDH with more active sites, and favors the formation of radicals with improved oxidative ability for photocatalysis.
