The emergence of the metaverse has ledto the rapidly increasing demand for the generation ofextensive 3D worlds. We consider that an engagingworld is built upon a rational layout of multiple landuse areas (e.g., forest, meadow, and farmland). Tothis end, we propose a generative model of landuse distribution that learns from geographic *** model is based on a transformer architecturethat generates a 2D map of the land-use layout,which can be conditioned on spatial and semanticcontrols, depending on whether either one or bothare provided. This model enables diverse layoutgeneration with user control and layout expansion byextending borders with partial inputs. To generatehigh-quality and satisfactory layouts, we devise ageometric objective function that supervises the modelto perceive layout shapes and regularize generationsusing geometric priors. Additionally, we devise aplanning objective function that supervises the modelto perceive progressive composition demands andsuppress generations deviating from controls. Toevaluate the spatial distribution of the generations, wetrain an autoencoder to embed land-use layouts intovectors to enable comparison between the real andgenerated data using the Wasserstein metric, which isinspired by the Fr´echet inception distance.

Designing ultrathick and hierarchical electrodes is effective to deal with the challenge of high areal capacity and high power density for lithium-ion batteries(LIBs)***,a thick electrode with hierarchical porous and multidimensional conductive network is fabricated by 3D printing tech-nology,in which both the conducting polymer of poly(3,4-ethylene dioxythiophene):polystyrene sul-fonate(PEDOT:PSS)and graphene oxide(GO)play the dual roles as binders and conductive *** a consequence,the 3D-printed thick electrode(~900 mm)with a mass loading of~47 mg/cm^(2) exhibits a good rate capability of 122 mA·h/g at 2 C,a high areal capacity of up to 5.8 mA·h/cm^(2),and stable cycling performance of~95%capacity retention after 100 ***,the C-O-S bond is further confirmed by the spectral analysis and the DFT calculation,which not only hinders the stack of nanosheets but enhances the mechanical stability and electronic conductivity of electrodes.A stable covalent multidi-mensional conductive network constructed by 3D-printing technology provides a new design strategy to improve the performance of LIBs.
