CoWO4 is predicted to be a very promising electrode material for supercapacitors. In this study, a novel flowerlike morphology of CoWO4 fabricated by a hydrothermal method is presented for the first time. The prepared CoWO4 have been thoroughly characterized by scanning electron microscopy and X-ray diffraction. The special CoWO4 nanostructure exhibits noticeable specific capacitance of 156 Fg -1 at 0.5 Ag -1 and shows outstanding rate capability (85.2% capacitance retention at 10 Ag -1 ). The proposed feasible route is expected to be applied prospectively and widely in preparing CoWO4 pseudocapacitive material, which owns great application value in supercapacitors.
Effect of Vonoprazan Fumarate Tablets in Patients with Reflux EsophagitisTo investigate the drug effects of vonoprazan fumarate tablets on reflux esophagitis and their adverse drug reactions is the objective of the study. A total of 102 patients with reflux esophagitis admitted to the Department of Gastroenterology of the Affiliated People's Hospital of Ningbo University from June 2021 to November 2022 were selected and randomly grouped, with 51 cases in the observation group and 51 cases in the control group. The observation group received vonoprazan fumarate tablets and the control group received rabeprazole for 8 w. The drug effects of the two groups were analyzed, including the duration of symptom relief, changes in esophageal motility, the level of serum gastric hormone, the injury degree of esophageal mucosa and the level of inflammatory factors. Adverse drug reactions were analyzed in the two groups. After medication, the symptom remission time, changes in esophageal motility, serum gastric hormone level, esophageal mucosa injury degree and inflammatory factor level in observation group were better than those in control group (p<0.05). The total incidence of dizziness, rash, diarrhea and other adverse drug reactions in the observation group was 3.92 %, which was significantly lower than that in the control group (9.8 %, p<0.05). In conclusion, vonoprazan fumarate tablets has obvious effect on the treatment of reflux esophagitis with low adverse reactions, which is worthy of clinical promotion.
Most of photocatalytic reaction taken place in a slurry type reactor, which is of poor light utilization and difficulty to recycling of photocatalyst. To overcome these drawbacks, a floating photocatalyst (TiO2/EP) was prepred by hrothermal method, in which EP(Expanded Perlite) was used as an substrate. Photocatalysts activity was evaluated under UV light using Rhodamine B as the pollutant model. The effect of heating temperature, heating time and dosage of EP on activity of TiO2/EP were Discussed. The results showed 2h and 200°C were the optimal conditions and the dosage of EP has no significant effect on activity of TiO2/EP. The results of XRD and SEM showed TiO2 is anatase form, well crystallized and dispersed; its particle size is about 100~150nm. This floating photocatalyst can remove about 97.4% rhodamine B(10mg/L) during 90min under UV light. It has broad prospects for engineering applications.
