Msorbate: Molecular weight of sorbate (in this study: Cu = 63.55 g mol−1). [Sorbate]°: Standard concentration of the sorbate (1 mol L−1). γ: Coefficient of activity (unitary for dilute solutions and dimensionless). [Math Processing Error]ΔH∘: Standard sorption enthalpy (kJ...
such as CeO2(111), CeO2(200), and CeO2(220). The crystal phase of copper could not be observed due to the lighter atomic weight of Cu with respect to Ce and the similar contrast
The above results suggest that spontaneous redispersion of Cu NPs in O2-H2O may occur through the oxidation of Cu atoms into atomic Cu-O species, followed by quick hydroxylation into atomic Cu-OH species and final capture by the support. Furthermore, we find that the oxidative redispersion proc...
Scanning electron microscopy (SEM) and atomic force microscopy (AFM) analysis showed rougher particle surfaces after dry grinding with high amounts of microstructural defects, while wet ground particles had cleaner and smoother surfaces. The dry ground surfaces exhibited accelerated dissolution as well ...
Morphological and structural control of amorphous nanomaterials is challenging due to the long-range disordered atomic arrangements. Herein, we firstly propose a controllable self-hydrolyzing etching-precipitating (SHEP) method to fabricate the regular-shaped amorphous Cu2MoS4 nanocages (a-Cu2MoS4 NCs)...
Low-molecular-weight volatile sulfur compounds were the main cause of reducing flavor and deteriorating quality in wine (Wang, Jia, et al., 2023; Wang, Ma, et al., 2023). In order to remove the reducing flavor imparted by H2S, mercaptans, and so forth, copper was often deliberately ...
reduction at the oxide metal intertire produces atomic hydrogen, which can be absorbed into the metal or recombine to form H2 gas. It is the production of atomic hydrogen (Equation 3) which makes water vapor such an aggressive environment for 7XXX series alloys. The production rate of hy...
and the highest H2evolution activity is obtained on ca. 1.5 wt% CuSA-TiO2(Supplementary Table1). More importantly, an unprecedented AQE of 56% at 365 nm has been achieved on the ca. 1.5 wt% CuSA-TiO2, a new record. These results indicate that both the large atomic weight percenta...
Excessive Cu2+ intake can cause neurological disorders (e.g. Wilson’s disease) and adversely affect the gastrointestinal, liver, and kidney organs. The presence of Cu2+ is strongly linked to the emergence and progression of Wilson's disease (WD), and ac
The development of electric vehicles and lightweight electronic devices has accelerated the demand for high-density energy storage systems [[1], [2], [3], [4], [5]]. Owing to the advantages of high theoretical specific capacity (3860 mAh g−1) and the lowest potential (−3.04 V vs...
