The development of efficient catalytic electrode toward oxygen reduction reaction (ORR) is still a great challenge for the wide use zinc–air batteries. Herein, Co2N nanoparticles (NPs) anchored on N-doped carbon from cattail were verified with excellent performances ORR. onset and half-wave potentials over optimal catalyst reach to 0.96 V 0.84 V, respectively. Current retention rates 96.8% afte...

Plant defense traits such as trichomes along with biocontrol agents may provide alternatives to insecticide use in tomatoes, Solanum lycopersicum L. (Solanaceae). However, plant-herbivore-natural enemy interactions are not always complementary. In a series of greenhouse and field experiments, we explored whether augmented (i.e., production acylsugars) tomato plants could reduce sweet potato whi...

Typha lepechinii, a new species from European Russia, is described. In terms of the external morphology, it similar to T. shuttleworthii but differs latter by shape female inflorescence, wider leaf blades and geographical distribution. Like shuttleworthii, lepechinii clearly distinct all other cattails sect. Ebracteolatae due its short male inflorescence that 2–4 times shorter than contiguous i...
