Titania nanotubes (TNT) prepared by anodization of Ti foils were used for water splitting in a standalone cell. The concentration polarization between the anode side (1M NaOH) and cathode side (0.5 M H2SO4) ensured that the water splitting reaction could take place with no external bias and separate H2 and O2 evolution could be achieved. The destructi...

Highly active and earth-abundant catalysts for hydrogen evolution reaction (HER) oxygen (OER) play vital roles in developing efficient water splitting to produce fuels. Here, we reported an effective strategy fabricate a completely new nitrogen-doped MoS2/COF-C4N vertical heterojunction (N-MoS2/COF-C4N) as precious-metal-free bifunctional electrocatalysts both HER OER. Compared with MoS2 COF-C4...

Herein, we have successfully prepared self-doped carbon dots with nitrogen elements (NCD) in a simple one-pot hydrothermal carbonization method, using L-histidine as new precursor. The effect of as-prepared was studied for photoelectrochemical (PEC) water splitting by decorating NCDs upon TiO2 nanorods systematically changing the loading time from 2 h to 8 (TiO2@NCD2h, TiO2@NCD4h, TiO2@NCD6h, a...

Alstromeria has beautiful flowers that is popular in the world. One of the most problem in commercial of this flower is ethylene sensitivity and bacterial contamination in stem end of cut flowers. In this experiment, effect of essential oils of bitter orange (0, 25 and 50 mg l-1) and lawson cypress (0, 100 and 200 mg l-1) and nonchemical treatment (with and without) with 18 treatments, 3 replic...

In situ straining experiments were performed in a TEM on an equimolar CoCrFeMnNi (Cantor) high entropy alloy at room and cryogenic temperature. Perfect partial dislocation activity recorded both cases. Twinning directly follows the development of shearing that has various origins (perfect splitting, anchoring). It is shown that, although twinning more frequently observed liquid nitrogen tempera...

Among hundreds of impurities and defects in diamond, the nitrogen-vacancy (NV) center is one most interesting to be used as a platform for quantum technologies nanosensing. Traditionally, synthetic diamond irradiated with high-energy electrons or nitrogen ions generate these color-centers. For precise positioning NV centers, fs-laser irradiation has been proposed an alternative approach produce...
