The kinetic process of a slow oxygen evolution reaction (OER) always constrains the efficiency of overall water electrolysis for H2 *** particular,nonprecious metal electrodes for the OER have difficulty in possessing excellent electrocatalytic activity and stability in pH-universal media *** this work,urea is first used as a pore-forming agent and active C/N source to fabricate a nanoporous NiFeCoCN medium-entropy alloy (MEA) by high-temperature sintering based on the nanoscale Kirkendall *** NiFeCoCN MEA achieves an overpotential of 432 mV at a current density of 10 mA·cm^(-2) and a lower Tafel slope of 52.4 mV·dec^(-1) compared to the IrO_(2)/Ti electrode (58.6 mV·dec^(-1)) in a 0.5 mol/L H_(2)SO_(4) *** a 1 mol/L KOH solution,the NiFeCoCN MEA obtains an overpotential of 175 mV for 10 mA·cm^(-2) and a Tafel slope of 40.8 mV·dec^(-1),which is better than IrO_(2)/Ni *** work proves a novel strategy to design and prepare nanoporous MEA materials with desirable C/N species,which provides promising prospects for the industrial production of H2 energy.

MXR7 is a cell-surface protein and highly expressed in hepatocellular carcinoma(HCC). The aim of this study is to determine the expression profile of MXR7 in HCC and investigate the influence of MXR7 on invasion and metastasis of HCC cells. For this purpose, immunohistochemical assay was used to identify the differential expression of MXR7 in 94 HCC specimens. Expression of MXR7 in 4 pairs of HCC and portal vein tumor thrombus(PVTT) was also tested. The motility of HCC cells were characterized by transwell migration and matrigel invasion assays. In vivo metastasis potential was determined via tail vein injection ***, compared with noninvasive HCC tumors or human HCC cell lines with low metastatic potential, invasive HCC samples and HCC cell lines with high metastatic potential exhibited higher MXR7 expression. Furthermore, forced expression of MXR7 in SMMC-7721 promoted cell proliferation, migration and invasion in vitro and accelerated tumor growth and metastasis in vivo. Conversely, knockdown of MXR7 expression in HuH7 cells inhibited proliferation and motility of cells. Mechanically,overexpression of MXR7 promoted epithelial-mesenchymal transition(EMT) progress, and MXR7 depletion repressed the EMT phenotype. In conclusion, MXR7 is a mediator of EMT and metastasis in HCC and may serve as a novel therapeutic target.

At present, in digital fingerprinting coding algorithm, AND-ACC based on BIBD is the most efficient and can precisely trace several colluders. But when the extracted fingerprint is damaged, a miscarriage of justice is likely to occur. And when the number of users becomes larger, the efficiency of algorithm declines rapidly. Here, combined ACC based on Euclidean Geometries （EG） with ECC, the first is used in the under layer. Then we use Turbo encoder to deal with the fingerprint sequences and get the output as the final fingerprint for users. The scheme has both their advantages. It makes the fingerprint more robust and reduces the mistake rate. Besides it can accommodate more users while it guarantees to find the same number of colluders.
