Two asymmetric schiff–base ligands L1,L2(L1= N-Furan-2-ylmethylene-N-{2-[(4-methoxy-benzylidene)-amino]-ethyl}-1,2-diamine,L2 = 4-Brome-2-[(2-{2-[Furan-2-ylmethylene)-amino]-ethylamino}-methyl]-phenol
硼中子俘获(BNCT)治疗癌症是利用中子束和10B发生原子核反应,释放高能粒子杀死癌细胞,是一种二元治疗模式[1,2]。目前临床使用硼携带剂都属于化合物型药物,缺乏对病灶部位的可控靶向聚集[3],含10B的纳米颗粒,特别是Fe2B磁性纳米颗粒,一方面具有磁性纳米材料的可控性,易修饰性,可以修饰各种生物靶向分子,另一方面具有较高的硼含量,是一种潜在的BNCT硼携带药物。
Lung cancer is a disease characterized by uncontrolled cell growth in tissues of the lung.As an antineoplastic agent,docetaxel(DTX)is considered as one of the most effective drugs in chemotherapy for
Nanomaterials with enzyme-like activity have received considerable attention over the past few decades because of their unique size,shape,composition and structure-dependent properties.Generally,the c
异核原子碰撞的研究对于制备异核分子，研究异核简并气体中的相互作用和基于碰撞的量子信息处理有着重要的基础意义。但由于异核碰撞过程中同时存在多种损失机制，极大地限制了特定异核碰撞信息的有效和精确提取。
近些年来,强场物理学界对非序列双电离的研究主要集中在低Z稀有气体原子,即He,Ne,Ar原子。在绝大多数实验观察中,双电子主要向同一个半球发射,即正关联。同时,在回碰阈值以下观察到Ar原子的双电子主要向相反半球发射,即反关联。
The sawtooth oscillations are realized by using the reduced magnetohydrodynamic(RMHD)model with single helicitiy and the toroidicity effects ignored in cylindrical geometry.
Since its discovery in 2009 [1,2],the low-energy structure(LES) in above-threshold ionization(ATI) spectrum at mid-infrared wavelengths has attracted increasing attention in past years.A closer inspec
When an atom or a molecule interacts with a strong laser field,the bound electron wavepackets can be emitted at different times.The different wavepackets with the same final momentum will interfere wi
增益引导(gain guided)是利用波导中增益差异，获得与传统波导利用折射率差限制光束传播类似效果的一种效应.A.E.Siegman等人利用增益引导效应提出了一种可以实现大模场面积单模传输的新型光纤——增益引导折射率反引导(gain-guided index-antiguided)光纤，为研究高功率、高光束质量的激光器或放大器提供了一种新的思路.
