Abstract Natural organisms have developed various biological ion channels/transporters to maintain normal life activities adapt changing environments. Significantly, transporters with active transport property show much more controllability on these due a variety of external stimuli, giving guidance construct artificial counterparts for overcoming the issues in simple nanofluidic systems restricted by self‐diffusive transport. Herein, 2D system based Janus membrane (i.e., JM) is constructed,...
The core-collapse supernova remnant (SNR) Cassiopeia A (Cas A) is one of the brightest galactic radio sources with an angular radius $\sim$ 2.5 $\arcmin$. Although no extension this source has been detected in $\gamma$-ray band, using more than 1000 days LHAASO data above $\sim 0.8$ TeV, we find that its spectrum significantly softer those obtained Imaging Air Cherenkov Telescopes (IACTs) and flux near 1$ TeV about two times higher. In combination analyses 16 years \textit{Fermi}-LAT...
Salinity gradient energy harvesting is still limited to rather small working areas in laboratories. Here, we report a thylakoid-inspired nanofluidic system based on two-dimensional homogeneous multilayer membrane for salinity harvesting, assisted by light-driven active ion transport. The assembled graphene oxide (GO) nanosheets decorated with photoelectric 5,10,15,20-tetrakis(4-aminophenyl) porphyrin molecules, denoted as TGO. Upon light illumination the low concentration side, photovoltaic...
The environment of actively repeating fast radio bursts (FRBs) has been shown to be complex and varying. recently localized FRB 20190520B is extremely active, the largest confirmed host dispersion measure, only second source associated with a compact, persistent (PRS). main tracer magneto-ionic environments rotation measure (RM), path-integral line-of-sight component magnetic field strength (B) electron density, which does not allow direct probe B-field configuration. Here we report evidence...
