a NiSO4 + b Co = c Co2SO4 + d Ni Step 2: Create a System of Equations Create an equation for each element (Ni, S, O, Co) where each term represents the number of atoms of the element in each reactant or product. Ni: 1a + 0b = 0c + 1d S: 1a + 0b = 1c + 0d O...
The interaction of nickel carbonyl, Ni(CO)4, with evaporated palladium and iron surfaces has been studied at 90 and 290 K by X-ray photoelectron spectroscopy. The carbonyl is weakly adsorbed in molecular form at 90 K on the metals giving a Ni 2p32 peak at 854.6 eV, a C 1s at 287.2 ...
(Ni5.2WCu2.227, CoNiMo28) has been reported as an efficient approach to improve the activity and more than an order of the magnitude enhancement compared with pristine Ni has been achieved. Cooperating with non-metal elements, such as doping N or O in catalyst nanoparticle or substrate (e.g...
(Fig.4d), showing the excellent biocompatibility of Ni SACs/N-C under the conditions employed here. Further toxicity tests showed that more than 80% of HUVECs maintain cell viability after co-cultured with different concentrations of Ni SACs/N-C for 48 h (Supplementary Fig.12). We then ...
XMoO4(X = Ni, Co). Between them, the NiCo2O4@NiMoO4electrode material showed a highest areal capacitance of 3.74 F/cm2at 2 mA/cm2, which was much higher than the NiCo2O4@CoMoO4electrode material (2.452 F/cm2), and good rate capability, implying its prospect as an alternative...
For example, different crystal phase of CoNi was electrodeposited as an electrode for urea electro-oxidation [62]. Among the prepared Co-fcc, Co-hcp, Co7Ni3-fcc, Co7Ni3-hcp, Co5Ni5-fcc, and Ni-fcc films, Co7Ni3-hcp film was found to have better electrocatalytic performance. New ...
performance via external electric field treatment. Based on the RS mechanism, a large number of conductive filaments consisting of OVs are formed in the Co3O4film after treated by an electric field, which reduces the resistance of the Co3O4film by almost 2 × 104times. The high ...
