Ni/ZnO nano-sponges have been successfully synthesized through optimized annealing of Ni/Zn-based organic framework (Ni/Zn-MOF). The annealed MOF provides the stable carbon structure with 3D interconnection and prevents structural collapse during the charging and discharging process. The annealing causes the incorporation of intrinsic Ni^(3+) in the surface of NiO nanoparticles, providing more reaction active sites. The oxygen vacancies in ZnO and heterostructure interfaces between NiO and ZnO promote the charge transformation. Based on the aforementioned advantages, the Ni/ZnO nanocomposites exhibit excellent electrocatalytic performances for supercapacitors. The specific capacitance can reach to 807 F·g^(−1) at 1 A·g^(−1) in the studied electrodes. After 5,000 cycles at 10 A·g^(−1), the cyclic stability remains excellent at 86% of the initial capacitance. Moreover, the as-prepared asymmetric supercapacitor exhibits a high energy density of 30.6 W·h·kg^(−1) at power density of 398 W·kg^(−1). This study is expected to provide new insights into exploring the potential mechanism of catalyst action.

Our preliminary studies demonstrated that Metacavir has potential to become a new anti-HBV agent. The main targets of the toxic effects of Metacavir, in rhesus monkeys, were gastrointestinal tracts, liver, blood, and kidneys, which were not related to mitochondrial effects. In this study, the maternal toxicity, embryo-fetal developmental toxicity and teratogenicity were studied in pregnant Sprague-Dawley rats after intragastric administration of Metacavir （200, 100, 50, 0 mg/kg body weight） during the first 6-15 days of pregnancy. Slower weight gain was observed in 5 out of 21 rats subjected to a 200 mg/kg dose, as well as 2 out of 20 subjected to a 100 mg/kg dose. Compared with the solvent control group, the calibration weight gain in the 200 mg/kg and 100 mg/kg dosage groups respectively, during first 6-20 pregnant days were significantly different （P 〈 0.01, P 〈 0.05）. Significant dose related adverse effects to other reproductive parameters were not seen in F0 and F1, but the number of stillbirths in high dose group showed notably difference compared with the control group （P 〈 0.05）, while the litter incidence showed no difference. No Metacavir-associated pathological changes were observed. The present research indicated that at a dose of 200 mg/（kg·d）（i.e., 40 times the effective dose in rats）, Metacavir shows some maternal toxicity to SD rats. The embryotoxicity in the 200 mg/kg group encompass decreased fetal body weight, and higher fetal mortality rates, compared with the control group. However, the litter incidence showed no statistical difference. All the treated rats displayed normal bone development, no teratogenicity and without adverse effects on fetal development, thus indicating that below a dose of 200 mg/（kg· d） there is no teratogenic side effects.
