Cu-based materials are commonly used in electrocatalytic nitrate reduction reactions（NO3RR）. NO3RR is a “two birds, one stone” approach, simultaneously removing NO3-pollutants and producing valuable ammonia（NH3）. However, the strong coordination between the NO3-intermediate and the catalytic active sites seriously hinders the conversion efficiency. Here, we determined that, through encapsulation strategies, the carbon layer could weaken the NO3-intermediate binding to active sites, resulting in higher NH3yields. We experimentally fabricated electrocatalysts, i.e., Cu nanoparticles encapsulating（or loaded on） N-doped carbon nanofibers（NCNFs） called Cu@NCNFs（Cu-NCNFs）, using electrostatic spinning. As a result,Cu@NCNFs can achieve NH3yields of 17.08 mg/(h·mgcat) at a voltage of-0.84 V and a Faraday efficiency of 98.15%.Meanwhile, the electrochemical properties of the Cu nanoparticles on the surface of carbon fibers（Cu-NCNFs） are lower than those of the Cu@NCNFs. The in situ Raman spectra of Cu@NCNFs and Cu-NCNFs under various reduction potentials during the NO3RR process show that catalyst encapsulation within carbon layers can effectively reduce the adsorption of N species by the catalyst, thus improving the catalytic performance in the nitrate-to-ammonia catalytic conversion process.

maca （Lepidium meyenii Walp, 2n = 8x = 64）, belonging to the Brassicaceae family, is an economic plant cultivated in the central Andes sierra in Peru （4000-4500 m）. Considering that the rapid uplift of the central Andes occurred 5-10 million years ago （ma）, an evolutionary question arises regarding how plants such as maca acquire high-altitude adaptation within a short geological period. Here, we report the high-quality genome assembly of maca, in which two closely spaced maca-specific whole-genome duplications （WGDs; ~6.7 ma） were identified. Comparative genomic analysis between maca and closely related Brassicaceae species revealed expansions of maca genes and gene families involved in abiotic stress response, hormone signaling pathway, and secondary metabolite biosynthesis via WGDs. The retention and subsequent functional divergence of many duplicated genes may account for the morphological and physiological changes （i.e., small leaf shape and self-fertility） in maca in a high-altitude environment. In addition, some duplicated maca genes were identified with functions in morphological adaptation （i.e., LEAF CURLING RESPONSIVENESS） and abiotic stress response （i.e., GL YClNE-RICH RNA-BINDING PROTEINS and DNA-DAmaGE-REPAIR/TOLERATION2） under positive selection. Collectively, the maca genome provides use- ful information to understand the important roles of WGDs in the high-altitude adaptation of plants in the Andes.
