“…In addition, weak phonon coupling occurs between two or more nanostructures, such as van der Waals cross interfaces [178,179] and double-wall nanotubes [180,181]. The interaction at these interfaces is primarily due to the van der Waals force, which is weaker than the interatomic chemical bonds within the systems.…”

Recently, emerging phonon phenomena have been discovered and rapidly developed, which have become an active hot research topic. In this review article, we present state-of-the-art advances in several fascinating phonon transport phenomena. First, we summarize the recent progress on the wave nature of phonons, including phonon coherence and its effects on thermal conductivity and the topological properties of phonons. Then, we discuss the particle nature of phonons, including the weak coupling of phonons and the high-order phonon anharmonicity. Finally, we present the summary and a brief outlook. This review presents the advanced understanding of some emerging phonon phenomena in solid materials, which provides new opportunities for further advancement in a wide variety of applications.

“…This new conceptual solar cell may hold advantages in simultaneously achieving flexibility, durability, non-toxicity, and sustainability, which would exceptionally be important for future applications such as wearable devices. The unique geometry of hetero-nanotubes may result in other interesting physical and chemical properties and enable other possibilities from many aspects beyond photoelectronic and photovoltaic devices, which are being discussed in recent publications from various research groups [16,[26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41]. For example, Zhang et al [42] studied the property of a SWCNT-BNNT 1D heterostructure film as the saturable absorber and demonstrated a high optical damage threshold; Suzuki et al [38] observed a memristive behavior in CNT-BNNT heterostructure bulk assemblies and proposed these fibers could be useful for future neuromorphic computing and conventional nonvolatile memory devices.…”

We recently demonstrated experimentally the synthesis of one-dimensional (1D) van der Waals (vdW) heterostructure, where single-crystal hexagonal boron nitride or molybdenum disulfide nanotubes seamlessly wrapped a singlewalled carbon nanotube and formed a coaxial hetero-nanotube with the diameter typically being 1-5 nm. 1D vdW heterostructures have created large room for fundamental research from synthesis to application, but most directions are still at their initial stages. The materials that can be employed to construct 1D vdW heterostructures are limited to only a few types. In this review, we provide an outlook to the question: what are the building blocks available now and could be available in the future for the fabrication of 1D vdW heterostructures?

“…模拟方面 , Li等 [63] 利用分子动力学方法研究了应变场对二维硅材料热导率的影响, 表明当硅纳米线由拉伸状态转为压缩状态时, 其热导率会不断提高, 这是由于模态化声子的群速度和单独声子支的比热在纳米线压缩过程中均发生下降造成的. Yang等对应力对一维材料的热导率影响进行了系统性研究, 包括二硫化钼纳米管 [64] 、一维范德华异质结构(碳-氮化硼纳米套管) [65] 、环氧树脂原子链 [66,67] 等, 发现应力可以高效调控一维材料的热导率, 调控幅度最高可达到r = 30. 实验方面, Yu等 [68] 研发了一种液态金属泡沫弹性体复合材料, 当应变率达到400% 时, 可实现r = 3.5的调控幅度.…”

Effective thermal control technologies are increasingly demanded in various application scenarios like spacecraft systems. Thermal conductivities of materials play a key role in thermal control systems, and one of the basic requirements for the materials is their reversibly tunable thermal properties. In this paper, we briefly review the recent research progress of the thermal smart materials in the respects of fundamental physical mechanisms, thermal switching ratio, and application value. We focus on the following typical thermal smart materials: nanoparticle suspensions, phase change materials, soft materials, layered materials tuned by electrochemistry, and materials tuned by specific external field. After surveying the fundamental mechanisms of thermal smart devices, we present their applications in spacecraft and other fields. Finally, we discuss the difficulties and challenges in studying the thermal smart materials, and also point out an outlook on their future development.
