The gases used were: ARCAL 10Footnote 2 and a custom gas mixture cgmFootnote 3, which are further filtered by an AirLiquide ALPHAGAZ O2-free purification system that lowers the oxygen content from the one-digit ppm down to the one-digit ppb range. 3 Results Surface tension and density of ...
whereσc, electrostatic breakdownis the collected charges from electrostatic breakdown (generally air breakdown), which can be improved by the enhanced thermionic emission of electrons or the avalanche breakdown effect27. However, the reported maximum value is only 0.64 mC m−2due to th...

However, achieving ultrasmall and high-density nanoparticles (optimal catalysts) faces fundamental challenges of their strong...
We tested this hypoth- esis by removing two, four or six uppermost leaves from top of a plant at three days after silking, with no-leaf removal as control, to understand whether higher N accumulation in kernels of maize at high density could be achieved through optimum leaf removal, to ...

The room temperature was monitored and adjusted if necessary using air conditioning, considering that the outdoor temperature was usually > 25°C. The arm was positioned at the level of the heart and immobilized using a vacuum cushion (a specially constructed pillow filled with polyurethane ...
To reduce the air influence on highly reactive Li, the surface of Li/LiZn@Cu samples was covered with Kapton tape before XRD measurements. In-depth XPS spectra were explored through Thermofisher Scientific ESCALAB Xi+ with monochromatic Al Kα radiation. All samples were processed in glove box...
·6H2O (Aldrich, 98 + %), and citric acid into distilled water. Precursor solutions were infiltrated into porous PBMCo with various weight percent to parent material (3, 7, and 12wt%) and then calcined in air at 450 °C for 4 h. This infiltration procedure was repeated to ...

Carbon-supported nanoparticles are indispensable to enabling new energy technologies such as metal-air batteries and catalytic water splitting. However, achieving ultrasmall and high-density nanoparticles (optimal catalysts) faces fundamental challenges of their strong tendency toward coarsening and agglomeration...
