A contour-parallel offset （CPO） tool-path linking algorithm is derived without toolretractions and with the largest practicability. The concept of ＂tool-path loop tree＂（TPL-tree） providing the information on the parent/child relationships among the tool-path loops （TPLs） is presented. The direction, tool-path loop, leaf/branch, layer number, and the corresponding points of the TPL-tree are introduced. By defining TPL as a vector, and by traveling throughout the tree, a CPO tool-path without tool-retractions can be derived.

采用电泳沉积法在铜箔上沉积碳纳米管,层层堆叠后在不同烧结温度(550,650,750,850,950℃)下热压烧结制备碳纳米管增强铜基(CNTs/Cu)复合材料,研究了烧结温度对复合材料显微组织和力学性能的影响。结果表明:随着烧结温度升高,复合材料中孔隙的数量减少,尺寸减小,碳纳米管分布均匀性增大,铜晶粒尺寸增大,退火孪晶晶粒尺寸增大但数量减少;随着烧结温度升高,复合材料的抗拉强度和显微硬度均呈先减小后增大的趋势,断后伸长率变化呈非单调性变化;当烧结温度为650℃时,复合材料的抗拉强度和显微硬度适中,断后伸长率最大,综合力学性能最好。

N, P co-doped carbon/MoO3-x hybrids(NPC/MoO3-x) were synthesized via one-step pyrolysis of molybdophosphate-based ionic salt precursor. Doped carbon and oxygen vacancies(OVs) were synchronously introduced into the NPC/MoO3-x hybrids without any other redundant procedure. As anodes for lithium-ion batteries, the NPC/MoO3-x hybrids delivered a high initial Coulombic efficiency(ICE) of 81% as well as high charge capacity of 516 mA·h/g after 100 cycles at 1 A/g, indicating the excellent reversibility and rate capability. The enhanced lithium storage performance was attributed to the rational combination of surface engineering and OVs, which is beneficial to the more active sites and fast ionic/electronic transport.

Since first synthesized in 2011, MXenes have attracted extensive attention in many scientific fields as a new two-dimensional(2D) material because of the unique physical and chemical properties. Over the past decade, in particular, MXenes have obtained numerous exciting achievements in the field of terahertz applications. In this review, we first briefly introduce the MXene materials, such as the basic structure and main fabrication processes of MXenes. Then, we summarize the recent applications of MXene materials in various terahertz research areas, including terahertz modulation, terahertz absorption, terahertz shielding, terahertz communication, terahertz detection and terahertz generation, in which the representative results are presented. Finally, we give an outlook on the future research directions of MXene materials and their potential applications.

The U.S. Geological Survey has estimated a 99% chance of a magnitude 6.7 earthquake in California in the next 30 years from 2008. In this paper, Fourier transform, mode analysis and commensurability analysis are used to study the earthquake cycle in California and predict the future strong earthquake. The analysis shows that the strong earthquake in California is most likely to occur in 2019, and the prediction was sent to the relevant institutions of United States in 2018. In July 2019 an M7.1 earthquake occurred in California, which proved our prediction to be correct.

The aim of this study is to explore whether RT-5, one novel active ginsenosides from Ginseng, has protective effects against cisplatin（CDDP）-induced nephrotoxicity in vivo. One model of acute renal failure induced by CDDP in rats and one model of xenograft tumors of human cervical cancer in nude mice are established. Four groups are assigned： control, CDDP, RT-5, CDDP plus RT-5, in which the RT-5 is administered via oral gavage 24 h before CDDP intraperitoneal injection. The significant increase in blood urea nitrogen and creatinine are induced by CDDP treatment at 6 mg/kg, which are attenuated by pre-treated with RT-5 at 10 mg/kg. RT-5 could ameliorate CDDP-induced morphological damages in kidney by PAS staining, and reduce tubular apoptosis evaluated by TUNEL staining. Pretreatment with RT-5 notably inhibits CDDP-induced oxidative stress in kidney tissues. Interestingly, RT-5 does not interfere with the in vivo anti-cancer effects of CDDP against the growth of xenograft tumors in nude mice. These data suggest that co-treatment RT-5 with CDDP might attenuate the following nephrotoxicity without inhibiting its anti-tumor efficiency, which could provide one novel strategy for cancer treatment in clinics.
