ABSTRACT This article investigates how TikTok Shop reproduces the e‐commerce model of Douyin Shop against a backdrop of divergent regulatory challenges and geopolitical distrust. One of the strategic changes we observe in TikTok Shop is the shift of consumer goods suppliers from local merchants to China‐based sellers.

Laser‐Driven Halide Exchange and High‐Resolution Multicolor Patterning of Perovskite Films
ABSTRACT Translating the excellent properties of metal halide perovskites (MHPs) into practical flexible optoelectronic devices requires high‐resolution multicolor patterning techniques that are compatible with post‐fabrication processing. However, such a capability has remained elusive.

ABSTRACT High‐entropy alloys (HEAs) have attracted considerable interest from researchers owing to their tunable chemical compositions, exceptional structural stability, and promising catalytic properties. However, their large‐scale application is often hindered by complex manufacturing techniques and poor durability.

ABSTRACT The development of sodium‐ion batteries (SIBs) is limited by slow charge transfer kinetics and large material volume changes caused by the large radius of Na+. Leveraging the excellent physicochemical properties and unique heterostructures of metal selenides, ultrafine hetero‐CuFeSe2‐CoSe2 nanoparticles are in situ wrapped by ...

ABSTRACT Multimodal luminescent materials are crucial for advanced information encryption, real‐time dosimetry, and high‐resolution bioimaging, yet integrating orthogonal stimulus‐responsiveness into a single‐component system is challenging. Herein, we report a Pr3+‐doped Ca3Ga2Ge3O12 (CGGO: Pr3+) garnet phosphor that exhibits orthogonally addressable ...

Microphase separation of mixtures of two diblock copolymers(两嵌段共聚物共混体系的相分离研究)
用耗散粒子动力学方法(DPD)研究了由两种不同成分组成的两嵌段共聚物组成的混合体系在纳米尺度下的自组装行为.两种嵌段共聚物的聚合度相同,在稳定状态下,纯嵌段共聚物1呈层状有序结构,纯嵌段共聚物2呈无序或六角柱状结构.DPD研究表明,在两者混合体系中,随着嵌段共聚物2体积分数的增加,嵌段共聚物1只出现了层状的有序相,而嵌段共聚物2则呈现出从球状相到柱状相再到层状有序相的有趣变化,随着嵌段共聚物2对称性的增强,其形成的有序相所占的体积分数区域越小.同时,通过混合体系单体密度分布曲线和末端距分布情况 ...
