| 1 | Influences of Annealing Temperature and Doping Concentration on Microstructural and Optical Properties of CeO_2:Sm^(3+) Nanocrystals显示文摘Nanocrystals of CeO2 with different doping concentrations of Sm3+were synthesized by a novel and costeffective method. The crystal structure, morphology and particle size were systematically investigated by X-ray diffraction,scanning electron microscopy and transmission electron microscopy. Effects of the annealing temperature and doping concentrations on the microstructural properties of the crystals were studied. X-ray diffraction analysis indicates that the cubic structure of the Ce O2 is not affected by the doping of Sm3+up to a doping concentration of 20%. Different structural parameters such as lattice constant, surface area, bulk density and porosity of the crystal were determined and discussed.Microscopic images of the CeO2:Sm3+suggest that the thermal decomposition of oxalate precursor is a suitable synthesis pathway to produce uniform-sized microparticles and nanoparticles. The influences of annealing temperature and doping concentration of Sm3+on the optical properties of the nanocrystals were also discussed. The photoluminescence excitation spectra reveal that the charge transfer band is redshifted with increasing annealing temperatures. Emission attains its maximum intensity for Sm3+concentration of 1%, and higher concentrations lead to emission quenching. | G.Vimal Kamal P.Mani P.R.Biju Cyriac Joseph N.V.Unnikrishnan M.A.Ittyachen | 2015 | Acta Metallurgica Sinica(English Letters)2015，28，6： | 2 |

| 3 | Critically Ill COVID-19 Patient with Chronic Liver Disease-Insights into a Comprehensive Liver Intensive Care显示文摘The novel coronavirus-related coronavirus disease 2019(COVID-19)pandemic has been relentless in disrupting and overwhelming healthcare the world over.Clinical outcomes of COVID-19 in patients with chronic comorbidities,especially in those with metabolic syndrome,are well documented.Chronic liver disease and cirrhosis patients are a special subgroup,among whom the management of COVID-19 is challenging.Understanding the pathophysiology of COVID-19 in patients with cirrhosis and portal hypertension improves our identification of at-risk patients for disease progression that will further help compartmentalize generalized and specialized treatment options in this special patient group.In this exhaustive review,we critically review the impact of COVID-19 on the liver and in chronic liver disease and cirrhosis patients.We further discuss common features associated with the pathophysiology of COVID-19 and cirrhosis,based on the renin-angiotensin system and deliberate current literature on guidelines for the treatment of COVID-19 and extrapolate the same to the cirrhosis population to provide a concise and stepwise,evidence-based management for cirrhosis patients with severe and critical COVID-19.There are no specific management guidelines for cirrhosis patients with COVID-19 and current recommendations for treatment are as per guidelines for general population.Nevertheless,specific issues like avoiding corticosteroids in decompensated patients with variceal bleeding,suspected sepsis,high grade hepatic encephalopathy and acute kidney injury,use of early mechanical ventilation strategies in those with severe ascites and hepatopulmonary syndrome,avoidance of remdesivir in advanced liver disease,and application of liver-specific severity scores for prognostication and identification of futility need to be highlighted. | Cyriac Abby Philips Kamna Kakkar Moby Joseph Praveen Kumar Yerol Rizwan Ahamed Sasidharan Rajesh Philip Augustine | 2021 | Journal of Clinical and Translational Hepatology2021，9，4： | 0 |
