A Ge-based metal-organic framework (MOF) precursor [C6H10(NH2)2Ge3O6] is used to fabricate two-dimensional GeO2 nanosheets in this work. The obtained micrometer-sized GeO2 nanosheet delivers superior lithium-storage capability during long cycling (an initial reversible capacity of 1315mAhg−1 at 100mAg−1 and the retained capacity of 1393mAhg−1 after 350cycles). The observed large capacity and good...
Metal-organic-frameworks (MOF) derivation has been demonstrated to be an effective strategy to obtain porous metal oxides with controlled morphologies and improved electrochemical properties for lithium-ion batteries. One-dimensional mesoporous NiO nanorod is synthesized for the first time in this work from a rod-like Ni-MOF precursor, which is formed by a fast and facile room-temperature reaction...
To reveal the migration and transformation rule of nitrogen in the vadose zone and groundwater and to determine the migration mathematical model, we researched the migration and transformation rule of ammonia nitrogen, nitrate nitrogen, nitrite nitrogen in the vadose zone and groundwater by the soil column leaching experiment. The results indicate: using ammonium bicarbonate shows a stronger alkalinity...
Two kinds of antioxidant activities in liver of fish were investigated. Fish was exposed to different concentrations (1/6LC50,1/4LC50,1/3LC50,1/2LC50) and killed at 3, 7,14, 21 and 28 day after exposure. The activities of Peroxidase (POD) and Catalase (CAT) in liver tissue were analyzed. The results indicated the activities of POD and CAT were induced from the third day in all treatment groups at...
