Summary: Strong correlations within a symmetry-unbroken ground-state wavefunction may manifest in approximate density functional theory as symmetry-broken spin densities or total densities, arising from soft modes of fluctuations such as spin-density or charge-density waves. An approximate density functional that breaks symmetry can be more revealing than an exact functional that does not, with examples including the stretched H-2 molecule, antiferromagnetic solids, and the static charge-density wave/Wigner crystal phase of a low-density jellium. Time-dependent density functional theory quantitatively shows that the static charge-density wave is a soft plasmon, with the frequency of a related density fluctuation dropping to zero.

Summary: A ternary composite photocatalyst consisting of nickel sulfide supported on the heterojunction of ultrathin cadmium sulfide-carbon based on g-C3N4 nanosheets was successfully prepared in a low-temperature aqueous-phase method. The chemical compositions and morphology of the catalyst were confirmed by various characterization techniques. The addition of nickel improved the specific surface area of the catalyst, promoting carrier migration and reactant diffusion. The electron structures analysis revealed the transfer of electrons from g-C3N4 to CdS at the heterojunction interface, with strong interaction between CdS and g-C3N4. The hydrogen evolution performance demonstrated that the ternary composite photocatalyst outperformed the single systems and binary systems. This study provides a solution to the high recombination rate of photo-electrons and holes, as well as the insufficient active sites in single materials.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
