Metal-based … ku bsn programjobs dollar30 an hour An amino acid has the general formula H₂N-CH (R)-COOH, where R stands for the different acids. Notice that the central C atom is chiral — it has four different groups attached — so the molecule can exist as a pair of enantiomers (nonsuperimposable mirror images). One of these is the D isomer, and the other is L (i.e. a pair of R/S isomers). Nano Co 3 O 4 particles were synthesized by a simple precipitation method and studied as anode material in lithium-ion and sodium-ion batteries. Co 3 O 4 electrodes exhibited superior cycling performance in Li-ion cells than Na-ion cells.
