2015).Cyanobacterial toxinshave expanded their range beyond lakes in the mid-west US, most likely linked to eutrophication (Fristachi et al., 2008). A key factor is believed to be the supply of N as urea (a commonly used nitrogen form in fertilizer), which can cause a 200–400% increas...
10 February 2017 Nitrogen-doped amorphous carbon-silicon core-shell structures for high-power supercapacitor electrodes S. A. Safiabadi Tali1,2, S. Soleimani-Amiri3, Z. Sanaee1,2 & S. Mohajerzadeh2 We report successful deposition of nitrogen-doped amorphous carbon films to realize...
Grids were mounted in a custom-built manual plunging device (Max Planck Institute of Biochemistry) and excess liquid blotted with filter paper (Whatman no. 1) from the backside of the grid for 5–7 s prior to freezing in a 50:50 ethane:propane mixture (Airgas) cooled by liquid nitrogen....
The ratio, connecting thermal and physical characteristics of water, temperature of the cooled environment and phase transition, thickness and time of the ice making process, is resulted. The diagram of rated dependences and experimental data of water ice making on a flat surface by nitrogen is ...
Figure3a is a schematic diagram of the corresponding catalytic action of the inner (CeO2NPs) and outer layers (Au NPs) of CZA. After the successful preparation of CZA, electron spin resonance spectroscopy was utilized to explore the ability of CZA to catalyze free radical production and free ...
(e.g., nitrogen, phosphorus, selenium, sulfur, oxides, and hydroxides) of Ni nanostructures and double-layered (DL) structures are known to have outstanding properties toward OER and/or HER [14]. However, despite high catalytic performance and thermal stability, the low electrochemical stability ...

it has high partial pressures of hydrogen (80-85 bar) and nitrogen (about 30 bar) and it is known that in these operating conditions hydrogen and nitrogen corrode the surface of the steels. This requires the use of high-quality steels and large-thickness walls, thus significantly increasing ...
The above core and shell morphology changes during annealing can be understood on the basis of the Ti-N phase diagram defined as: in Fig. 3c 23. In term of the lever rule, the weight percentage of α-Ti shell network (Vα) can be Vα = W − Wβ Wα − Wβ iwnh...
