The doping of electron-accepting nitrogen atoms on the carbon plane of conjugated nanotubes seems to make adjacent carbon atoms have a relatively high positive charge density. This effect, coupled with aligning the NCNTs, provides a four-electron pathway for the ORR on VA-NCNTs, and the ...
Regimes of continuous spin detonation in a plane–radial combustor with an external diameter of 80 mm with peripheral injection of a hydrogen–oxygen mixture in the range of specific flow rates of the mixture 3.6–37.9 kg/(s ·m 2 ) are obtained for the first time. Depending on the ...

We report measurements of the oxygen-isotope effect (OIE) on the in-plane penetration depth ${\\ensuremath{\\lambda}}_{\\mathrm{ab}}(0)$ in underdoped ${\\mathrm{La}}_{2\\ensuremath{-}x}{\\mathrm{Sr}}_{x}{\\mathrm{CuO}}_{4}$ single crystals. A highly sensitive magnetic to...
She was right.1was tired and felt like l was running on empty.‘ ‘And what are you doing for you?" "There's no way I have time for me,"I said. "Deb,there's no way you don't have time for you.Think of yourself as being in a plane,and it's going down.You have a lot ...
However, the origin of ORR activity on Fe-N-C catalysts is still unclear, which hinder the further improvement of Fe-N-C catalysts. Herein, we provide a model to understand the ORR activity of Fe-N4 site from the spatial structure and energy level of the frontier orbitals by density ...
An oxygen absorber for blending in a resin, comprising a mixed powder containing an iron powder, a metal halide and an alkaline substance, and having a half-peak width on a plane (110) of 0.20°/2θ (Co—Kα) or less as measured by a pow... Y Ishizaki,K Fukue,K Seno 被引量:...
In addition, •OH specifically bound the [CNb3] site of the Nb2C plane and was efficiently eliminated. The 2D ultrathin Nb2C-PVP MXenes could effectively eliminate oxidative damage caused by IR, restore activity of SOD, and improve liver injury (Fig. 10B). The survival rates of mice ...

In the OER regime the normalized cloud length is continuously decreasing on the anodic scan, whereas the relative thickness reaches a plateau and remains unaltered (as shown in Supplementary Fig. 12). This means that the liquid thickness is reduced in the in-plane direction (due to the ...
