(Fe-N-CDs)), the intrinsic POD activity of CDs was distinctively strengthened, endowing the Fe-N-CDs based immunoassay with superior catalytic activity than HRP [81]. In addition, by virtue of great electron transfer ability, plenty of active sites, and feasible 2D or 3D structure of ...
Because the strength of the X-ray diffraction of single crystal X-ray analyses depends on the total number of electrons of all atoms existing in the unit cell, it is usually difficult to observe atoms with poor electron density, such as hydrogen, after structural refinements. In contrast, if...
of spinel Co3O4which led to the formation of a geometric configuration unit PO6, triggering electron rearrangement ofcobalt ions. This resulted in the development of highly active Co2+sites on the catalyst surface thereby decreasing the energy barrier of the rate-determining step. The resulting...

Select the correct answer. Which of the following elements makes up the majority of Earth's atmosphere? a. Oxygen b. Hydrogen c. Argon d. Nitrogen Elements in the atmosphere Although the Earth's atmosphere contains a lot of ...
Would you expect each of the following atoms to gain or lose electrons when forming ions? What ion is most likely in each case? a. Na b. Sr c. P d. BaUsing only the periodic table, write the expected ground-state electron confi...
Thus, the heterotroph likely uses organic compounds (unidentified) released by the Cyanobium into the culture medium as an energy source, as well as using the oxygen produced by the Cyanobium as a terminal electron acceptor. The subject Cyanobium grows well under a wide variety of pH and ...

Moreover, it is noted in Fig. 6b that a great number of micro-cracks are distributed in the Ti-N shells, suggesting that cracks were nucleated first within the Ti-N shell regions, and were blunted or impeded by the soft Ti cores (indicated by arrows), resulting in the moderate ...
