Band structure of tellurium. It was reported 35 as early as in 1950s, followed by a few other researchers in 1970s (refs 30, 32, 36, 43, 44, 45).Very recently, the detailed band structure has been ...

Here, we show that few-chain and single-chain van der Waals tellurium nanowires can be isolated using carbon nanotube and boron nitride nanotube encapsulation. With this approach, the number of atomic chains can be controlled by the inner diameter of the nanotube. The Raman response of the structures suggests that the interaction between …

Here, we presented a novel strategy for coordinating the chemotherapy drug CDDP with a tellurium-containing polymer, which restrained the tumour cytotoxicity of these two portions. After low dose γ-radiation, CDDP departed from the coordination complexes, and the tumour cytotoxicity of both was restored.
