The nucleating seed effect of hexagonal boron nitride (h-BN) has been proved to contribute to the single orientation of in-plane h-BN/graphene heterostructures with epitaxial stitching on Ni(111) surfaces, and the growth of h-BN prior to that of graphene is essential to achieve this goal.

Modulating the local coordination environment of single-atom catalysts for enhanced catalytic performance

Xinyuan Li^1,2, Hongpan Rong¹ (*), Jiatao Zhang¹, Dingsheng Wang² (*), and Yadong Li²

The local coordination environment of single-atom catalysts exhibits significant effects on their catalytic performance. In this review, we will focus on the characterization of coordination environment, tailoring of the local coordination environment, and their related adjustable catalytic performance.

Single-atom catalysis enables long-life, high-energy lithium–sulfur batteries

Zechao Zhuang¹, Qi Kang², Dingsheng Wang¹ (✉), and Yadong Li¹ (✉)

Single-atom catalysts (SACs) open up huge possibilities of achieving long-life, high-energy lithium–sulfur batteries. In this review, we summarize the very recent advances in utilization of SACs for the improvement of sulfur cathode, cell separator, and lithium metal anode.

Drain-engineered carbon-nanotube-film field-effect transistors with high performance and ultra-low current leakage

Lijun Liu, Chenyi Zhao, Li Ding, Lianmao Peng (*), and Zhiyong Zhang (*)

A drain-engineered feedback-gate structure is adopted in high-performance carbon-nanotube-film-based field-effect transistors, to cope with the common issue of poor off-state properties and ambipolar behavior. Our results show 2 orders of magnitude reduction in off-current while maintaining 0.2 mS/μm high transconductance, and succesfully meet the 10 nA/μm logic-technology standard-performance power requirement.

Thickness-dependent wrinkling of PDMS films for programmable mechanochromic responses

Zhiwei Li, Yun Liu, Melinda Marin, and Yadong Yin (*)

This work reveals the thickness dependence of the wrinkling behaviors of plasma-treated polydimethylsiloxane (PDMS) films. For thick films, the wrinkles can be predicted by the classic nonlinear finite mechanics, giving rise to brilliant structural colors. For thin films, the wrinkles are large and random. These observations provide new opportunities for understanding the wrinkling mechanics and have promising applications in smart optical materials.
