1. 铁性纳米材料的可控合成与制备 

Controlled Synthesis of Ferroic Nanomaterials

我们致力于发展可靠的铁电、铁磁纳米材料的化学合成方法（如溶胶凝胶、水热、高温热裂解等）和物理制备方法（如溅射、脉冲激光沉积、原子层沉积等）。通过控制反应条件，控制晶体生长的动力学和热力学，从而调控材料的组分、形貌、缺陷种类和密度，进一步调控其光、电、磁、热等物理性能。

We are dedicated to developing the reliable chemical synthesis methods (such as sol-gel, hydrothermal, thermal decompositions, etc.) and physical preparation methods (such as sputtering, pulsed laser deposition, atomic layer deposition, etc.) for ferroelectric and ferromagnetic nanomaterials. By controlling the reaction conditions to adjust the kinetics and thermodynamics of crystal growth, we can regulate the composition, morphology, defect type and density of the materials, which can further influence the optical, electrical, magnetic, and thermal properties.

2. 铁性纳米材料中的新物性探究

Exploring Novel Physical Properties of Ferroic Nanomaterials

当纳米材料足够小时，尺寸效应便会显现。这时，材料会表现出许多不同于宏观尺度上的性能，例如：磁性材料的超顺磁状态、铁电材料中铁电性的消失、挠曲电效应占比的放大、氧化物材料的超弹性和形状记忆效应等等。我们也对这些随着尺寸减小而逐渐显现的材料的新奇特性感兴趣。一方面，我们会探寻这些材料中新奇物性（结构上）的来源，以及探究用何种手段可以去有效调控这些新奇的物性；另一方面，我们也会挖掘这些具有新物性的材料的应用潜力。

Size effects appear when materials turn to nano. Examples include superparamagnetic effect, dissappearance of ferroelectricity in nanoparticles, and so on. We are also interested in those emerging phenomena as the size decreases. On one hand, we explore the sources of these novel physical properties, and investigate the methods how to effectively regulate these novel properties. On the other hand, we also explore the potential applications of these materials with novel physical properties.

3. 磁-力-电-化学的多场耦合效应

Magneto-Mechano-Electro-Chemistry Coupling

压电材料和磁电耦合材料分别在外力和外磁场的作用下，会发生极化状态的改变，导致其表面上电荷发生不对称分布。产生的极化电场或者表面电荷可以用于引发或者增强某些化学反应。与传统的电化学反应相比较，磁电-化学或者压电-化学耦合效应不需要有线的电极，靠声波震动或磁场就可以无线地引发化学反应，因而在某些场合下会有重要的应用，例如狭小空间内的污物清理或者远程控制人体内药物递送。

Under external forces or magnetic fields, the polarization states of the piezoelectric or magneto-electric coupling materials will change respectively, leading to an asymmetric distribution of surface charges. The generated electric fields or surface charges can be used to initiate or enhance certain chemical reactions. Compared to the wired electroded electrochemical reactions, magneto-electro-chemical and piezo-electro-chemical coupling effects can wirelessly trigger chemical reactions through magnetic fields or acoustic vibrations. Such effects makes those materials useful in certain scenarios, such as cleaning the contaminants in confined spaces or remotely controlling the drug delivery within the human body.
