Material research from the viewpoint of functional motifs

As early as 2001, the need for the ‘functional motif theory’ was pointed out, to assist the rational design of functional materials. The properties of materials are determined by their functional motifs and how they are arranged in the materials. Uncovering functional motifs and their arrangements is crucial in understanding the properties of materials and rationally designing new materials of desired properties. The functional motifs of materials are the critical microstructural units (e.g. constituent components and building blocks) that play a decisive role in generating certain material functions, and can not be replaced with other structural units without the loss, or significant suppression, of relevant functions. The role of functional motifs and their arrangement in materials, with representative examples, is presented. The microscopic structures of these examples can be classified into six types on a length scale smaller than ∼10 nm with maximum subatomic resolution, i.e. crystal, magnetic, aperiodic, defect, local and electronic structures. Functional motif analysis can be employed in the function-oriented design of materials, as elucidated by taking infrared non-linear optical materials as an example. Machine learning is more efficient in predicting material properties and screening materials with high efficiency than high-throughput experimentation and high-throughput calculations. In order to extract functional motifs and find their quantitative relationships, the development of sufficiently reliable databases for material structures and properties is imperative.

技术创业企业商业模式创新前因的组态效应

为剖析技术创业企业商业模式创新多重前因的联动效应,基于商业模式冰山理论构建了商业模式创新的前因要素模型,以31家技术创业企业为样本,采用模糊集定性比较分析方法,分析了技术创业企业商业模式创新多重前因的联动效应。研究结果表明:(1)技术创业企业商业模式创新具有"多重并发"和"殊途同归"的特点,单一要素难以构成商业模式创新的必要条件;(2)网络嵌入与资源整合能力的协同作用对技术创业企业商业模式创新至关重要;(3)在高度的环境不确定情况下,资源整合能力和机会识别能力的协同作用,以及网络嵌入和战略柔性的协同作用是技术创业企业商业模式创新的重要途径。本研究进一步发展了商业模式冰山理论,丰富了商业模式创新前因的研究成果,为解释既有研究的分歧提供了新视角,也为技术创业企业根植自身情境实现商业模式创新提供了理论指导。

Rollback,scissor-like closure of the Mongol-Okhotsk Ocean and formation of an orocline:magmatic migration based on a large archive of age dataOA

Tracing the closure of oceans with irregular margins and the formation of an orocline are crucial for understanding plate reconstruction and continental assembly.The eastern Central Asian Orogenic Belt,where the Mongol-Okhotsk orocline is situated,is one of the world’s largest magmatic provinces.Using a large data set of U-Pb zircon ages,we updated the timing of many published igneous rocks,which allowed us to recognize tightly ’folded’ linear Carboniferous-Jurassic magmatic belts that wrap arou...     

Identification of twist-angle-dependent excitons in WS2/WSe2 heterobilayersOA

Stacking atomically thin films enables artificial construction of van der Waals heterostructures with exotic functionalities such as superconductivity, the quantum Hall effect, and engineered light-matter interactions.In particular, heterobilayers composed of monolayer transition metal dichalcogenides have attracted significant interest due to their controllable interlayer coupling and trapped valley excitons in moiré superlattices. However, the identification of twist-angle-modulated optical tr...
