Metallic nanoparticles with excellent size controllability and high loading rate are obtained via ultrafast high temperature shock *** Bi/CNRs-15 electrode exhibits an unprecedented rate performance (237.9 mAh g-1 at 2 A g-1) at - 60 degrees C, while the energy density of the full cell can reach to 181.9 Wh kg-1 at - 40 degrees C.A novel strategy of high-rate activation is proposed to obtain high capacity and superior stability at low temperature by creating new active sites for interfacial reaction. Sodium-ion batteries have emerged as competitive substitutes for low-temperature applications due to severe capacity loss and safety concerns of lithium-ion batteries at - 20 degrees C or lower. However, the key capability of ultrafast charging at ultralow temperature for SIBs is rarely reported. Herein, a hybrid of Bi nanoparticles embedded in carbon nanorods is demonstrated as an ideal material to address this issue, which is synthesized via a high temperature shock method. Such a hybrid shows an unprecedented rate performance (237.9 mAh g-1 at 2 A g-1) at - 60 degrees C, outperforming all reported SIB anode materials. Coupled with a Na3V2(PO4)3 cathode, the energy density of the full cell can reach to 181.9 Wh kg-1 at - 40 degrees C. Based on this work, a novel strategy of high-rate activation is proposed to enhance performances of Bi-based materials in cryogenic conditions by creating new active sites for interfacial reaction under large current.

BACKGROUND: Most patients waiting for liver transplantation have end-stage liver diseases with malnutrition, which is prone to induce intestinal barrier dysfunction after liver transplantation. We aimed to study the effect of probiotics on intestinal barrier function in malnourished rats following liver transplantation with long-term antibiotics. METHODS: Twelve Lewis rats were selected as donors. Twelve BN rats, which served as recipients, were subjected to malnutrition by semi-starvation for 4-5 weeks. They were randomly divided into two groups: a control group which received phosphate-buffered saline and a probiotics group which received Bifidobacterium and Lactobacillus. All recipients were injected with intramuscular imipenem and subcutaneous cyclosporine A. Furthermore, six normal BN rats without any drugs or operations served as a normal group. Eight days after operation, all rats were sacrificed for examination of the following parameters: serum levels of endotoxin and TNF-α, bacterial translocation, intestinal microflora, ileocecal sIgA, lymphocyte numbers, and phenotypes (CD4, CD8, αβTCR, γδTCR)ofPeyer’spatches. RESULTS: In recipients subjected to malnutrition, weight decreased by 20% and they survived until 8 days after operation. Compared with the normal group, all recipients on postoperative day 8 showed increased levels of serum endotoxin and TNF-α as well as increased counts oftranslocated bacteria. Meanwhile, there were decreases in counts of Bifidobacterium and Lactobacillus in the ileocecum, sIgA concentration, and lymphocytes of Peyer’s patches. Moreover, partial alteration in lymphocyte phenotypes was evidenced by elevated ratios of CD8 + and γδTCR + lymphocytes. In contrast, compared to the control group, supplementation with probiotics reduced the levels of serum endotoxin, TNF-α and bacterial translocation, increased the counts of Bifidobacterium and Lactobacillus, the concentration of sIgA and lymphocytes of Peyer’s patches, and also slightly

基于动力模型相似理论,设计了一个尺寸为1∶10的偏压隧道模型进行大型振动台试验,研究模型分别在大瑞人工波、Kobe波和汶川波水平竖向双向激振条件下偏压隧道的加速度、动应变和围岩压力的动力响应特性。试验结果表明:偏压隧道竖向加速度响应与地震波、振幅和测点位置有关,且对激振加速度有放大效应,但随输入加速度峰值的增大而减小,受临空坡面放大效应的影响,同一高程靠近坡面的偏压侧放大系数大于非偏压侧(除拱脚外);水平向加速度响应主要与测点位置关系较大,受波形和振幅影响较小。衬砌在地震作用下主要承受拉应力,主应力随输入加速度峰值的增大而增大,非偏压拱脚主应变值最大是抗震设防的关键部位。
