| 1 | Adsorption behavior of uranium on polyvinyl alcohol-g-amidoxime:Physicochemical properties, kinetic and thermodynamic aspects显示文摘Amidoxime-based adsorbents are widely studied as the main adsorbent in the recovery of uranium from seawater.However,the adsorption rate and loading capacity of such adsorbents should be further improved due to the economic viability consideration.In this paper,polyvinyl alcohol functionalized with amidoxime(PVA-g-AO)has been prepared as a new adsorbent for uranium(Ⅵ)adsorption from aqueous solution.The physicochemical properties of PVA-g-AO were investigated using infrared spectroscopy(IR),scanning electron microscope(SEM),X-ray diffraction(XRD),and X-ray photoelectron spectroscopy(XPS).Results showed that the ligand monomers were successfully grafted onto the matrixes.The XRD and XPS analysis showed that uranium was adsorbed in metal ionic form rather than in crystal form.Uranyl(U(Ⅵ))adsorption properties onto PVA-g-AO were evaluated.The adsorption of U(Ⅵ)by PVA-g-AO was fast,with an equilibrium time of less than 50 min.Additionally the maximum adsorption capacity reached 42.84 mg/g at pH 4.0. | CHI FangTing HU ShengX HU Sheng XIONG Jie WANG XiaoLi | 2013 | Science China Chemistry2013，56，11： | 10 |

| 3 | Ecological pressures on grassland ecosystems and their conservation strategies in Northern China显示文摘In this study,we identified ecological pressures on grassland ecosystems and adaptive countermeasures in Northern China.Our research revealed that the main sources of these pressures included population growth,economic development,resources exploitation,and global climate change,with human-related activities being overriding factors.Overgrazing was an important reason for grassland imbalance,causing soil erosion and desertification,especially during the sensitive spring greening phase.In steppe zones,commercial coal mining was destructive to the ecological environment.Regarding long-term strategies,we recommend that policy-makers devote more consideration to a new conceptual approach for transforming grasslands through shifting the focus from die grassland's traditional production functions to meir ecological functions.Applying this concept,adaptive countermeasures should be developed to reduce human impacts based on the environmental capacities of grasslands.Moreover,we recommend the development of environment-friendly industries and reduction of pressures from human activities as effective measures for maintaining the balance between sustainable economic development and grassland conservation.Lastly,we suggest that restoration of degraded grasslands should conform to the principle of natural vegetation to further improve the ecological adaptability of plants and ecosystem stability.This study is expected to provide scientific support for policy-makers engaged in grassland protection. | Zhirong Zheng Chaoyang Feng Shengxing Ye Zhaoyan Diao Shihai Lü | 2015 | Chinese Journal of Population,Resources and Environment2015，13，1： | 4 |
| 4 | Guided elastic waves in infinite flee-clamped hollow cylinders显示文摘Guided elastic-wave-inspection technique for hollow cylinders has received plenty of attention in recent years because of its high effciency and low cost. To apply guided elastic waves to defects detection, it is necessary to investigate the propagation of guided waves in the hollow cylinders under all kinds of boundary conditions. In this paper, the dispersion equations of torsional, longitudinal and flexural guided waves in the hollow cylinders with traction-free and clamped lateral boundaries are derived by elastodynamic theory, based on which the phase and group velocity dispersion curves of the guided waves mentioned above are obtained. And the dispersion properties of these waves are discussed in detail. The transient wave in a free-clamped hollow cylinder is simulated by the finite element method (FEM). The time-frequency distribution of the transient wave agrees well with the theoretical group velocity dispersion curves. | Liguo Tang Shengxing Liu | 2009 | Progress in Natural Science:Materials International2009，19，3： | 2 |
