Its lyophilized kit was developed for instant preparing of188Re-HEDP.188Re-HEDP showed high focile uptake in normal mice(> 30% ID/g at carrier co-injection) in BABLC/SPF mice. High quality single photon emission computed tomography(SPECT) image of New Zealand rabbit was obtained at 4 h after intravenous injection of 74 MBq radiotracer. The lyophilized HEDP kit affords the new opportunity for routine clinical application in bone metastases therapy.展开更多
[目的]烧结钕铁硼(NdFeB)磁体在声电磁性器件中的应用日益广泛,但其耐蚀性较差,一般需要进行有效的表面处理以提高其耐腐蚀性能和使用寿命。[方法]采用以羟基乙叉二膦酸(HEDP)为主配位剂的碱性无氰体系对烧结Nd Fe B磁体表面电镀铜。研...[目的]烧结钕铁硼(NdFeB)磁体在声电磁性器件中的应用日益广泛,但其耐蚀性较差,一般需要进行有效的表面处理以提高其耐腐蚀性能和使用寿命。[方法]采用以羟基乙叉二膦酸(HEDP)为主配位剂的碱性无氰体系对烧结Nd Fe B磁体表面电镀铜。研究了HEDP质量浓度对Cu镀层外观、表面粗糙度、厚度、结合力和耐蚀性的影响。[结果]HEDP的质量浓度为100~150 g/L时所得Cu镀层表面较光亮,厚度约为1.55μm,表面粗糙度较低,结合力和耐蚀性最佳。[结论]适宜的HEDP浓度有利于获得综合性能较好的Cu镀层。展开更多
