为了研究纳米TiO2对底泥汞的释放及活化的影响，采用模拟淹水实验，分析纳米TiO2对底泥和上覆水中总汞和甲基汞浓度的影响，并结合底泥中各形态汞的变化情况探讨纳米TiO2对汞的迁移转化的影响。结果表明，纳米TiO2可促进底泥中汞的释放，导致更多的汞释放到水中，与对照相比，4g·kg-1纳米TiO2导致上覆水中总汞浓度最高时上升91.32%，最终土壤汞的释放量增加约10%，主要原因是纳米TiO2可促进氧化态汞的溶解，这可能会提高水体汞污染的风险。此外，在本实验条件下，短期内纳米TiO2可能降低了底泥甲基汞的形成和释放，但长期淹水后没有明显的影响。总体来看，纳米TiO2对底泥汞释放和转化的影响随浓度升高而增大。因此，随着底泥或土壤中纳米TiO2含量的升高，其对汞的地球化学循环过程的影响可能加剧。

采用碱性水热-共沉淀法，将6种金属化合物(CaCl2、ZnCl2、MgCl2、FeCl3、AlCl3、CoCl3)两两组合生成9种不同类型的层状双金属氢氧化物并覆膜于常用垂直流人工湿地沸石基质表面；利用分别填充原始沸石及9中LDHs覆膜改性沸石基质的模拟垂直流人工湿地小试系统进行除磷净化实验，并结合10种沸石基质的等温吸附实验结果，对LDHs覆膜改性沸石基质除磷效果均有不同程度的提高；Zn2+参与合成的改性基质除磷效果优良，其中ZnFe-LDHs改性沸石基质对总磷、溶解性总磷及磷酸盐的平均去除率超过90%，其最大理论吸附量达到了原始沸石基质的3倍；LDHs覆膜改性沸石基质通过增加化学吸附容量、提高物理吸附能力达到强化除磷效果的目的。

This planet has been endowed with a host of natural mechanisms to keep the environment and climate in balance. Humans are now facing the need to restore this balance that has been upset in the past years because of a growing population and resource demands. To steer dependency away from freshwater crops and decrease environmental damage from humanity s fuel and energy demands, it is necessary to take advantage of the natural adaptive biomass resources that are already in place. Using methods of "Green Planet Architecture," based on compilations of current research and procedures, could lead to new forms of energy and fueling as well as new sources for food and feed. Green Planet Architecture involves climatic adaptive biomass; geospatial intelligence; agri- and aqua-culture life cycles; and soil, wetland, and shoreline restoration. Plants such as Salicornia, seashore mallow, castor, mangroves, and perhaps Moringa can be modified (naturally, model-assisted, or genetically) to thrive in salt water and brackish water or otherwise not arable conditions, making them potentially new crops that will not displace traditional farming. These fueling sources also have potential to be used in other rapid-growth industries, such as the aviation industry, that have incentive to move towards more sustainable fuel supplies. This report highlights an example of how synergistic development of biomass resources and geospatial intelligence high-performance computing capabilities can be focused to resolve potential drought-famine problems. These techniques provide a basis for future e-science-based discovery (and access) through technology that can be expanded to support global societal applications.

Municipal solid waste management generally refers to the management of solid waste from residential societies, streets, public places, commercial buildings, hospitals, and other institutions. Management of these types of waste is mainly the responsibility of municipal and other governmental authorities. Municipal solid waste management is one of the major problems being faced worldwide. Municipal solid waste is a part of the larger universe of waste and mostly includes the waste collected under the formal municipal programs. Proper and efficient management of municipal solid waste can contribute to the mitigation of many problems related to pollution, climatic changes, and public health.
