1Study on adsorption behavior of cesium using ammonium tungstophosphate(AWP)-calcium alginate microcapsules显示文摘A functional microcapsule was prepared by encapsulating the fine crystalline ammonium tungstophosphate(AWP) in calcium alginate polymer(CaALG).The characterization of AWP-CaALG microcapsule was examined by SEM and EPMA.The adsorption behavior of Cs(I),Rb(I),Sr(II),Pd(II),Ru(III),Rh(III),La(III),Ce(III),Dy(III) and Zr(IV) was investigated by the batch method.The batch experiments were carried out by varying the shaking times,HNO 3 concentration,and initial concentration of metal ions.Relatively large K d values above 10 5 cm 3 /g for Cs(I) were obtained in the range of 0.1-5 M HNO 3,resulting in a separation factor of Cs/Rb exceeding 10 2.In contrast,the K d values of Sr(II),Pd(II),Ru(III),La(III),Dy(III),Ce(III) and Zr(IV) were considerably lower than 50 cm 3 /g.The K d value of Cs(I) decreased in the order of the coexisting ions,H + > Na + >> NH 4 +,and a linear relationship with a slop of about 1 was obtained between log K d and log [NH 4 + ]([NH 4 + ] > 0.01 M).The adsorption of Cs(I) was found to be controlled by chemisorption mechanism,and followed a Langmuir-type adsorption equation.A high uptake percentage of 99.4% for Cs(I) was obtained by using the dissolved solutions of spent fuel from FBR-JOYO(JAEA).WU Yan MIMURA Hitoshi NIIBORI Yuichi OHNISHI Takashi KOYAMA Shinichi WEI YueZhou 2012Science China Chemistry2012,55,9:11
2Pro-and anti-epileptic roles of microglia显示文摘Microglia are brain-resident immune cells that contribute to the maintenance of brain homeostasis.In the epileptic brain, microglia show various activation phenotypes depending on the stage of epileptogenesis.Therefore, it remains unclear whether microglial activation acts in a pro-epileptic or anti-epileptic manner.In mesial temporal lobe epilepsy, one of the most common form of epilepsies, microglia exhibit at least two distinct morphologies, amoeboid shape and ramified shape.Amoeboid microglia are often found in sclerotic area, whereas ramified microglia are mainly found in non-sclerotic area;however, it remains unclear whether these structurally distinct microglia share separate roles in the epileptic brain.Here, we review the roles of the two distinct microglial phenotypes, focusing on their pro-and anti-epileptic roles in terms of inflammatory response, regulation of neurogenesis and microglia-neuron interaction.Shinichi Kinoshita Ryuta Koyama 2021Neural Regeneration Research2021,16,7:5
