Ni-W-GO composite coatings were successfully plated on 45# steel substrate by co-electrodeposition technique in a Ni-W electrolyte solution, with different contents of graphene oxide (GO) nanoparticles in suspen? sion. The structure, phase composition and surface morphology of as-plated composite coatings were characterized by Raman, X-ray diffraction (XRD), scanning electron microscopy (SEM) attached with energy disperse spectroscopy (EDS), respectively. The hardness and tribological behavior of the present coatings were also evaluated by Vickers Hardness tester and high-speed reciprocating friction and wear tester, and the wear mechanism was discussed as well. The results show that layer-structured GO nanoparticles significantly affect the microstructure and grain size of the Ni-W-GO composite coatings. Meanwhile, GO nanoparticles embedded in Ni- W-GO coatings can obviously improve the hardness and wear resistance in comparison with the corresp on ding Ni- W coatings. The highest microhardness and wear resistance of Ni-W-GO composite coatings are obtained with 0.15 g·L^-1 GO employing.

Boron carbide (B4C) is a rhombic structure composed of icosahedra and atomic chains, which has an important application in armored materials. The application of B4C under super high pressure without failure is a hot spot of research. Previous studies have unmasked the essential cause of B4C failure, i.e., its structure will change subjected to impact, especially under the non-hydrostatic pressure and shear stress. However, the change of structure has not been clearly understood nor accurately determined. Here in this paper, we propose several B4C polymorphs including B4C high pressure phases with non-icosahedra, which are denoted as post-B4C and their structures are formed due to icosahedra broken and may be obtained through high pressure and high temperature (HPHT). The research of their physical properties indicates that these B4C polymorphs have outstanding mechanical and electrical properties. For instance, aP10, mC10, mP20, and oP10-B4C are conductive superhard materials. We hope that our research will enrich the cognition of high pressure structural deformation of B4C and broaden the application scope of B4C.

沙漠化治理是一个全球性的难题。相较于传统的沙漠固沙技术,作为环境友好型固化材料的生物高分子聚合物,不仅能有效胶结沙漠砂以抵抗风蚀作用,还能提高沙漠砂的促生性能以促进植物生长,最终达到利用植被实现永久固沙的效果。基于前述设想,通过表面硬度试验、保水性能试验和植物生长试验研究了黄原胶(XG)、瓜尔胶(GG)以及二者的等质量混合胶(MG)生态固沙的效果。表面硬度试验表明生物高分子聚合物能有效胶结沙漠砂颗粒,质量分数为0.1%的XG、GG和MG溶液分别将沙漠砂的表面压力强度提高了9.4倍、5.3倍和8.0倍;保水性能试验表明生物高分子聚合物对沙漠砂保水性能的提升效果随溶液质量分数的增大而增大,在40℃高温养护条件下,生物高分子聚合物保水性能的比较结果为:XG>MG>GG;植物生长试验表明,在室内条件下,生物高分子聚合物能缩短植物出苗时间、提升植物的出苗率和幼苗高度,明显提高沙漠砂的促生性能。本文的研究初步表明,采用生物高分子聚合物实现生态固沙具备理论上的可行性。

初步探讨胃癌中异常增高的调节性T细胞(Treg)发挥免疫抑制的作用机制。利用多参数流式细胞术检测胃癌肿瘤局部CD4+CD25+Foxp3+Treg的Foxp3和环氧合酶2(COX-2)表达强度。CFSE增殖实验检测不同Foxp3表达强度的Treg对效应性T细胞的增殖抑制作用。在Treg与效应性T细胞共培养体系中加入COX-2抑制剂和前列腺素E2(PGE2)拮抗剂,观察PGE2的分泌水平以及Treg其对效应性T细胞的增殖抑制。结果发现,癌旁淋巴结和肿瘤浸润淋巴细胞(TIL)中Treg的Foxp3表达强度显著高于外周血(P<0.05);高表达Foxp3的Treg具有更强的抑制活性(P<0.05)。胃癌微环境中TregCOX-2表达强度与Foxp3表达强度显著相关(r=0.675,P<0.05)。应用COX抑制剂处理发现能阻断Treg分泌PGE2,COX抑制剂和PGE2拮抗剂均能降低Treg对效应T细胞增殖的抑制作用(P<0.05)。这表明胃癌局部高表达Foxp3的Treg具有较强的免疫抑制活性,COX-2-PGE2-EP2/EP4通路可能为胃癌微环境中Treg抑制效应T细胞增殖的机制之一。
