Anisotropy is one of the basic properties of crystals,and different facets of a single crystal may exhibit different physical and chemical properties.
A family of six new home lanthanide–coordination polymers incorporating conjugated ligand of 2,5-di(2,4-dicarboxylpheny)pyridine have been fabricated successfully through solvothermal reaction,namely,
Electrochemical water splitting needs catalysts made from earth-abundant elements to effectively drive the hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)[1].
In this work,we have developed a novel difunctional nanoplatform for targeted chemo-photothermal therapy based on hollow mesoporous silica nanospheres as a carrier for anticancer drug loading,CuS nano
随着现代电子信息产业的发展，电子产品在民用和军用领域得到了广泛的应用，同时也带来了电磁干扰、电磁污染、电磁泄密、电磁隐身等实际问题。新型轻质的吸波材料的研究成为科学家研究的热点。
Crystal defects have been extensively proved to have great influence on photocatalysis efficiency in solar-to-chemical energy conversion,but the factors including defect type and defect density has be
碳纳米管对反应物种和反应产物的特殊吸附及脱附性能、特殊的孔腔空间立体选择性、碳与金属催化剂的金属-载体强相互作用使催化研究工作者对碳纳米管在催化化学中的应用产生了极大的兴趣。
最近，一类被认为可以用来研究非厄密哈密顿有关奇特物理的光学系统，即满足宇称-时间(PT-)对称的光学系统，引起了极大的关注1.理想的PT 对称，要求光学系统具有完全均衡的增益和损耗分布，这对实验是个巨大的挑战.因此，有许多新颖的理论结果还没有得到实验验证.一种妥协的做法是，通过数学上的规范变化，建立非理想的PT 对称光学系统.
近年来,Lieb 光子晶格(photonic lattices,紧间隔的波导阵列)因其独特的带隙结构而受到广泛的关注1-6.紧束缚模型近似下,二维Lieb光子晶格带隙包含两个锥形能带和一个无衍射的平带,同时这三个能带在而且仅在狄拉克点处交叠.由于存在与石墨烯光子晶格7(photonic graphene)相似的锥形能带,Lieb晶格同样具有拓扑边缘态1,2、锥形衍射3、赝自旋4等性质；然而,与石墨
量子无损测量可以建立原子自旋间的纠缠，实现自旋压缩，从而将自旋投影噪声降低至其标准量子极限以下。实现量子无损测量的一个必要条件是要避免测量产生的反作用噪声。法拉第旋光法是一种对原子自旋极化进行量子无损测量的理想候选方法。然而法拉第旋光法中由于探测光偏振态量子涨落引起ac-Stark效应会产生光移反作用噪声。
