The key issue for lithium-ion batteries (LIBs) is their poor cycle stability. We report the rational design of a long-cycle-life anode material (i.e., MnO/C-N) composed of a three-dimensional (3D) nanoarchitecture for LIBs, based on the preparation from inexpensive, renewable, and abundant rapeseed pollen (R-pollen) in a remarkably simple process. The prepared MnO/C-N maintained a high specific discharge capacity of 513.0 mAh﹞g−1 (95.16% of the initial reversible capacity) after 400 charge/discharge cycles at a current density of 300 mA﹞g−1.

MoS2/single-walled carbon-nanotube (SWCNT) complementary inverters exhibit VinVout signal matching and achieve excellent performances with a high peak voltage gain of 15. The inverter performances are affected by the channel width-to-length ratios (W/L) of MoS2 field-effect transistors (FETs) and single-walled carbon-nanotube FETs. Therefore, W/L should be optimized to achieve a tradeoff between the gain and the power consumption.

Porous holey N-doped graphene (PHNG) was prepared using a convenient method that involved the pyrolysis of urea and magnesium acetate tetrahydrate for the generation of black foamlike products, which were then washed with dilute HCl. Thermally treated PHNG, which possesses the highest overall content of pyridinic and quaternary nitrogen, exhibits the best performance as a metal-free electrocatalyst for the oxygen reduction reaction.

A triboelectric nanogenerator based on variable microcapacitors embedded in polydimethylsiloxane (PDMS) was fabricated by filling PDMS with silver nanoparticles and constructing a cellular structure in PDMS. The structure provided improved accumulation of tribo-charges on the surface of PDMS by enhancing the capacitance.
