Host-guest-induced electronic state triggers two-electron oxygen reduction electrocatalysis Dynamic bonds offer unique advantages of adaptability and selectivity, yet, supramolecular electrocatalysts specifically tailored for 2e− pathway remain unexplored. Here, the authors report a host-guest strategy that...
The 1st Ionization energy(第一电离能):The energy needed to remove one electron from each atom in one mole of atoms of the element in the gaseous state to form one mole of gaseous 1+ ions 注意这里为气体状态下,1mol原子每个失去一个电子所需要的能量,其单位KJ/mol 我们在判断第一电离能在元素...
Meanwhile, the rich oxygen-containing groups and N-elements could be noted, inducing the evolution of electron-moving behaviors. More significantly, assisted by the inter-facial C-Se bonds and tiny Se distributions, Se electrodes are activated during cycling. Used as cathodes for Na-Se systems, ...
Meanwhile, due to the introduction of Fe-vacancies in FeS crystal, the adsorption capability and catalytic effect for LiPSs have been substantially enhanced. Moreover, the presence of Fe0.96S crystal favors the mobility of electron and diffusion of Li+, which is revealed by the experiments and ...
(Liang et al., 2021). The absorption band of Cu-TCPP nanosheet overlapped with the emission band of QDS-DNA (586 nm). Cu-TCPP nanosheets contained p-electronaromatic rings, which can attract and bind single-stranded DNA (ssDNA) on their large surface through π-π stacking intera...
The movement of one drop (0.6 ml) on the graphene film surface generated a voltage peak of 0.45 V (Fig. 13a, Table 1), a current of 4.8 μA (Fig. 13b) and a maximum power of 1.9 μW. The transduction mechanism is related to the positive and negative charges that ...
More details of the complex pathway are now revealed from the study of aluminium-ion relaxation through sequential electron-transfer-mediated decay. News & Views29 Aug 2023 Nature Chemistry Volume: 15, P: 1338-1339 How polymers dance to the pulses of ultrasound Scientists have been studying ...
Attosecond (asec) X-ray free-electron laser (XFEL) has attracted considerable interest over the past years. Nowadays typical XFEL application experiments demand 1010–1011 photons per pulse, which corresponds to a peak power of terawatts (TW) in case of asec hard X-ray pulse. To the realizati...
Density functional theory (DFT) calculations reveal that the Au-induced tensile strain on Pt-Co shell can not only boost the adsorption and dissociation kinetics of water at Co site by upshifting the d-band and promoting the electron transfer, but also downshift the d-band center of Pt in ...
