catalysts is that the atomic number of central B atom should be between group VB and VIIIB, and the electron difference between central A atom and B atom should be large enough, and the selectivity of NRR or hydrogen evolution reaction (HER) could be calculated through the prediction formula...
The TAG regioisomers in human milk, mammalian milk, lard and fish oil were identified and quantified using the developed methods. This study provided a reliable and facile method for analysis of the TAG regioisomers, which was capable of the selection of oil materials for infant formula ...
Up to 4 Na+ ion per formula unit can be inserted during the first discharge. An intensive refinement of the synchrotron X-ray diffraction (SXRD) patterns of discharged NaxCa0.5Ti2(PO4)3 evidenced the existence of five regions depending on the sodium content while the crystal ...
