The ability to detect light over a broad spectral range is central to practical optoelectronic
applications and has been successfully demonstrated with photodetectors of two-dimensional …

Three-dimensional (3D) Dirac point, where two Weyl points overlap in momentum space, is
usually unstable and hard to realize. Here we show, based on the first-principles calculations …

Metal-organic frameworks (MOFs) / porous coordination polymers (PCPs) have emerged as
a new family of conductive solid materials with outstanding performances in a wide variety of …

In December 2019, a coronavirus 2019 (COVID-19) disease outbreak occurred in Wuhan,
Hubei Province, China, and rapidly spread to other areas worldwide. Although diffuse alveolar …

Intertwining quantum order and non-trivial topology is at the frontier of condensed matter
physics 1 , 2 , 3 – 4 . A charge-density-wave-like order with orbital currents has been proposed …

Respiratory immune characteristics associated with Coronavirus Disease 2019 (COVID-19)
severity are currently unclear. We characterized bronchoalveolar lavage fluid immune cells …

Diabetes is a disease of increasing prevalence in the general population and of unknown
cause. Diabetes is manifested as hyperglycemia due to a relative deficiency of the production …

In 3D momentum space, a topological phase boundary separating the Chern insulating
layers from normal insulating layers may exist, where the gap must be closed, resulting in a “…

The search for large-gap quantum spin Hall (QSH) insulators and effective approaches to
tune QSH states is important for both fundamental and practical interests. Based on first-…

Graphene oxide membranes—partially oxidized, stacked sheets of graphene 1 —can provide
ultrathin, high-flux and energy-efficient membranes for precise ionic and molecular sieving …
