Nowadays,the electromagnetic properties of artificial photonic materials can be well-tuned via designs over their composition and geometries.However,engineering the properties of artificial materials at the nanoscale is challenging and costly.Here we demonstrate a facile and low-cost method for fabricating large-area silver nanoparticle metasurfaces(AgNPMSs)by using the vectorial holography-mediated growth technique.The AgNPMS,which can be regarded as a hologram device,possesses excellent chirop-tical properties.The vectorial holographic technique may open avenues for fabricating novel chiroptical metamaterials with large degrees of freedom,which can be further used for beam steering,photocatal-ysis,biosensing,etc.

Organic photovoltaic(OPV)cells have found their potential applications in the harvest of indoor light photons.However,the output power of such indoor devices is usually far from the demand of the internet of things.Therefore,it is essential to boost the o
Ion mobility analysis is a well-known analytical technique for identifying gas-phase compounds in fast-response gas-monitoring systems.However,the conventional plasma discharge system is bulky,operates at a high temperature,and inappropriate for volatile
Photocatalytic reduction of carbon monoxide (CO) is a promising route to the production of high-value chemicals and fuels,as a supplement to high energy-input Fischer-Tropsch synthesis (FTS) and a key step in direct photo/electro-reduction CO2 to multi-ca
Although deep learning has achieved a milestone in forecasting the El Nino-Southern Oscillation(ENSO),the current models are insufficient to simulate diverse characteristics of the ENSO,which depends on the calendar season.Consequently,a model was generat
A key to tackling the coronavirus disease 2019 (COVID-19) pandemic is to understand how severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) manages to outsmart host antiviral defense mecha-nisms.Stress granules (SGs),which are assembled during vi
Ferromagnetic quantum critical points were predicted to be prohibited in clean itinerant ferromagnetic systems,yet such a phenomenon was recently revealed in CeRh6Ge4,where the Curie temperature can be continuously suppressed to zero under a moderate hydr
The use of animals in research has long been debated.In partic-ular,the use of nonhuman primates(NHPs)in either basic or applied research is controversial[1,2].The concerns mainly arise from an ethical perspective given the great similarity between NHPs a
Hadrons made by diquark-antidiquark pairs(tetraquarks)are held together by QCD forces in an overall color singlet.As stated in the original proposals and similarly to baryons and qq mesons,tetraquarks form complete multiplets of the flavour symmetry,SU(3)
Thousands of proteins undergo arginine methylation,a widespread post-translational modification cat-alyzed by several protein arginine methyltransferases(PRMTs).However,global understanding of their biological functions is limited due to the lack of a com
The brain of the domestic pig(Sus scrofa domesticus)has drawn considerable attention due to its high similarities to that of humans.However,the cellular compositions of the pig brain(PB)remain elusive.Here we investigated the single-nucleus transcriptomic
