Modulation of interfacial interactions toward strong and tough cellulose nanofiber-based transparent thin films with antifogging feature
Cellulose nanofiber Transparent film Cross-linker Flexibility Toughness Antifogging
2023/12/1
Cross-linking is often performed to overcome the weak mechanical properties of native polymer films in order to expand their functional properties and applications. While this approach offers enhanced...
Self-Healable and Super-Tough Double-Network Hydrogel Fibers from Dynamic Acylhydrazone Bonding and Supramolecular Interactions
hydrogel fiber iota carrageenan dynamic covalent bond double network self-healing

Macroscopic hydrogel fibers are highly desirable for smart textiles, but the fabrication of self-healable and super-tough covalent/physical double-network hydrogels is rarely reported. Herein, copolym...
Producing biomaterials that match the performance of cartilage and tendons has been an elusive goal for scientists, but a new material created at Cornell demonstrates a promising new approach to mimic...
The strongest part of a tree lies not in its trunk or its sprawling roots, but in the walls of its microscopic cells.

具有两个谓词和一个论元的英语tough结构有其自身独具的句法语义属性。句法学家们在原则和参数理论框架下为该结构的推导生成提出了各种分析方案：论元移位、非论元移位、侧向移位以及拷贝—提升等分析法。但这些方案要么有违题元准则和/或格位过滤原则，要么混同了论元移位和非论元移位，因此都不能充分解释该结构的生成机制。本论文认为，未来基于最简方案的相关研究应该解决的核心问题是：该结构的主句主语和不定式句中的空...
