| 1 | Low-cost high entropy alloy(HEA)for high-efficiency oxygen evolution reaction(OER)显示文摘Oxygen evolution reaction(OER)is the key step involved both in water splitting devices and rechargeable metal-air batteries,and hence,there is an urgent need for a stable and low-cost material for efficient OER.In the present investigation,Co-Fe-Ga-NiZn(CFGNZ)high entropy alloy(HEA)has been utilized as a low-cost electrocatalyst for OER.Herein,after cyclic voltammetry activation,CFGNZ-nanoparticles(NPs)are covered with oxidized surface and form high entropy(oxy)hydroxides(HEOs),exhibiting a low overpotential of 370 mV to achieve a current density of 10 mA/cm^(2)with a small Tafel slope of 71 mV/dec.CFGNZ alloy has higher electrochemical stability in comparison to state-of-the art RuO2 electrocatalyst as no degradation has been observed up to 10 h of chronoamperometry.Transmission electron microscopy(TEM)studies after 10 h of long-term chronoamperometry test showed no change in the crystal structure,which confirmed the high stability of CFGNZ.The density functional theory(DFT)based calculations show that the closeness of d(p)-band centers to the Fermi level(EF)plays a major role in determining active sites.This work highlights the tremendous potential of CFGNZ HEA for OER,which is the primary reaction involved in water splitting. | Lalita Sharma Nirmal Kumar Katiyar Arko Parui Rakesh Das Ritesh Kumar Chandra Sekhar Tiwary Abhisek K.Singh Aditi Halder Krishanu Biswas | 2022 | Nano Research2022，15，6： | 5 |
| 2 | Elevated serum values of procollagen Ⅲ peptide (PIIIP)in patients with ulcerative colitis who will develop pseudopolyps显示文摘AIM: To assess the impact of procollagen Ⅲ peptide as a marker of collagenesis in the development of pseudopolyps in patients with ulcerative colitis.METHODS: Development of pseudopolyps was monitored in 25 patients with ulcerative colitis classified according to Powell-Tuck index as mild (n=12) or moderate (n=13) form of disease. Patients with a mild form of disease were treated with oral mesalazine medication (2-4 g/day) and local mesalazine preparation (suppository). Patients with a moderate form of disease received oral mesalazine medication (2-4 g/day), local mesalazine preparation(suppository) and local methylprednisolone at an initial dose of 60 rag/day, followed by dose tapering. How many significant variables (previously determined by analysis of variance) were elevated in the groups with and without pseudopolyp developement was observed. ROC analysis for calculation of new index was made.RESULTS: Serum values of procollagen Ⅲ peptide (PⅢP), C-reactive protein (CRP) and C4 complement component (C4)were statistically significantly lower in the group of patients flee from pseudopolyp development bhan bhose who developed one or more pseudopolyps (0.45±0.12 vs 1.42±0.70,P<0.0027; 7.6±4.7 vs 17.8±9.17, P<0.035, and 0.46±0.11 vs 0.34±0.16, P<0.068, respectively) at endoscopic conrtrols with patohistologically samples during 13 months. There were no statistically significant differences in the values of C3, ceruloplasmin and IgM between the two groups (P>0.05).Discrimination function analysis yielded highest standardized cannon coefficients for PⅢP (0.876), CRP (0.104), C3 (-0.534) and C4 (0.184) (P<0.036). The elevation in two of three laboratory variables (PⅢP, CRP and C4) reached sensitivity of 93 % and specificity of 90 % in the development of pseudopolyps.CONCLUSION: It is proposed that an increase in two of the three laboratory parameters (PⅢP, CRP and C4) could improve the accuracy of prediction of the development of pseudopolyps. When using PⅢP, CRP and C4 on decision making, the positive predictive value and accuracy were 90 % and 92 %, respectively. | ■arko Babi Vjekoslav Jagi Zvonko Petrovi Ante Bili KapetanoviDinko Goranka Kubat Rosana Troskot Mira Vukeli | 2003 | World Journal of Gastroenterology2003，9，3： | 2 |
