文化的生死作为既成事实,只能是指群体文化的生死。学术界专门研究过文化生死的学者,有斯宾格勒和汤因比。但这二人无论是对文化之生死的指认,还是对文化生死之因的解释,都存在谬误,不能成立。文化作为人类创造力的果实,从生物性意义的现代人类算起,其生即起点是晚期智人的原始群文化,其后相继演变为氏族文化和国家文化,而其死即终点则是文化的主人不复存在之时。其生的成因是人为了满足自身需求所进行的创造,死的原因是群体文化的创造者和使用者被外部力量消灭或打散。

Metastable seed-cry.tals: epitaxial growth of branched-array.organic heterostructure nanowires

引用

Science China Chemistry 2025年

作者： Jin Feng Zhen-y. Geng Ting-y.o Song y.ng-Xin Ma Chuan-Zeng Wang Wei Zhang Hong-Tao Lin Jin Zhou Shu-ping Zhuo Shu-Hai Chen Xue-dong Wang School of Chemistry.and Chemical Engineering Shandong University of Technology Institute of Functional Nano & Soft Materials (FUNSOM) Jiangsu Key Laboratory for Carbon-Based Functional Materials & DevicesSoochow University College of Chemistry.and Chemical Engineering Hunan Normal University

Tunable light–matter interactions are exhibited by.organic low-dimensional cry.tals, making these cry.tals a promising platform for organic photonics. However, the precise sy.thesis of organic low-dimensional cry.tals remains challenging due to the stochastic nature of molecular nucleation processes. Herein, the directed nucleation process is driven by.the introduction of metastable seed-cry.tals as the trunk, which ultimately.leads to branched-array.organic heterostructures. The successful formation of organic heterostructures with high-density.branched array. is attributed to the highest attachment energy.(Eatt（023）=-104.25 kcal mol-1) of the exposed （023） cry.tal plane during the seed-cry.tal growth route. Significantly. these as-prepared heterostructures inherently.have an ultralow lattice mismatch ratio η of 0.7%between trunk and branch, which contributes to the multi-channel photon transportation. Therefore, this work provides valuable insights into a versatile sy.thetic strategy.for accessing low-dimensional heterostructures for integrated optoelectronics.
