Although many efforts have been devoted to the adsorptive removal of phosphate from aqueous solutions and eutrophic water, it is still highly desirable to develop novel adsorbents with high adsorption capacities. In this study, Fe-based metal-organic frameworks (MOFs), MIL-101 and NH2-MIL-101, are fabricated through a general facile strategy. Their performance as an adsorbent for phosphate removal is investigated. Experiments are performed to study the effects of various factors on the phosphate adsorption, including adsorbent dosage, contact time and co-existing ions. Both MIL-101(Fe) and NH2-MIL-101(Fe) show highly effective removal of phosphates from aqueous solutions, and the concentration of phosphates decrease sharply from the initial 0.60 mg·L−1 to 0.045 and 0.032 mg·L−1, respectively, within just 30 min of exposure. The adsorption kinetics and adsorption isotherms reveal that NH2-MIL-101(Fe) has higher adsorption capacity than MIL-101(Fe) possibly due to the amine group. Furthermore, the Fe-based MOFs also exhibit a high selectivity towards phosphate over other anions such as chloride, bromide, nitrate and sulfate. Particularly, the prepared Fe-based MIL-101 materials are also capable of adsorbing phosphate in an actual eutrophic water sample and display better removal effect.

Hollow porous CoFe(2)O(4) nanocubes from metal-organic frameworks were fabricated through a general facile strategy. The intrinsic hollow nanostructure can shorten the lengths for both electronic and ionic transport, enlarge the surface area of electrodes, and improve accommodation of the volume change during Li insertion/extraction cycling. The hybrid multi-elements characteristics allow the volume change to take place in a stepwise manner during the electrochemical cycle. Therefore, the as-prepared CoFe(2)O(4) electrode exhibits outstanding performance as anode materials for lithium ion batteries. The stable capacity arrives at 815 mA h g(-1) for 20 C. Subsequently, a specific capacity of ca. 1043 mA h g(-1) is recovered when the current rate reduces back to 1 C after 200 cycles. This general strategy may shed light on a new avenue for large-scale synthesis of hollow porous hybrid nanocubes via MOFs for energy storage, environmental remediation and other novel applications.

Background: It has been proved in animal models that postconditioning (PC) could attenuate reperfusion injury. But there are not many clinical studies on the application of PC. Hypothesis: Four cycles of 1-minute balloon inflation and deflation, following initial balloon reperfusion in ST-segment elevation myocardial infarction (MI) but before stenting, might improve clinical outcomes compared with primary percutaneous coronary intervention (PCI) alone. Methods: Forty-three patients diagnosed with acute MI were randomly assigned to 2 groups: the control group (n = 20) and the PC group (n = 23). Blood samples were obtained and assayed for creatine kinase MB (CK-MB) and high-sensitive C-reactive protein. Electrocardiogram, echocardiography, and rest technetium Tc 99m-sestamibi (99mTc-MIBI) myocardial perfusion single-photon emission computed tomography (SPECT) were performed. Results:The control group presented with higher peak CK-MB as compared with the PC group (351.9 ± 153.6 vs 247.7 ± 118.3 U/L, P = 0.028) as well as the area under the curve (AUC) of CK-MB (8040 ± 3358 vs 5955 ± 2509, P = 0.04). After PCI, PC was associated with a lower level of hs-CRP in comparison with the control group (5.5 ± 4.5 vs 9.5 ± 5.2 mg/L, P = 0.019). More patients in the PC group had complete ST-segment resolution than did patients in the control group (82.6% vs 45.0%, P = 0.049). Left ventricle ejection fraction was better in the PC group than in the control group (0.57 ± 0.09 vs 0.47 ± 0.11, P = 0.002). Compared with the control group, PC greatly reduced infarct size, by 46% as measured by SPECT (13 ± 11.2% vs 24.2 ± 10.6%, P = 0.002). Conclusions: This study indicated that PC in emergent PCI was a valuable modification of primary PCI. IntroductionCoronary heart disease will become the leading cause of death worldwide by 2020. 1 Acute myocardial infarction (AMI) is a major cause of such mortality. Early and successful myocardial reperfusion with the use of thrombolytic therapy or percutaneous coronary intervention (PCI) is the most effective strategy for reducing the size of a myocardial infarct and improving the clinical outcome. But at the same time, the process of restoring blood flow to the ischemic myocardium can induce additional lethal injuries that are termed myocardial reperfusion injury. 2 Studies in animal models of AMI suggest that 50% of the final size of an MI is caused by myocardial reperfusion injury. 3 So new strategies for preventing reperfusion injury should be explored.Postconditioning (PC), defined as a cycle of brief interruptions of reperfusion applied at the onset of reperfusion after a prolonged ischemic insult, has been found to attenuate reperfusion injury in several animal experiments. 4 -7 In our study we applied this cardioprotective intervention at the time of myocardial reperfusion in 23 Chinese AMI patients receiving emergent PCI.

A facile generic environmental strategy is employed to prepare hierarchical yolk-shell hybrid NiO@C materials viz. metal-organic frameworks. The intrinsic yolk-shell nature as well as the multi-element characteristics of active components of the unique nanostructures contributes greatly to the outstanding electrochemical performance.
