Summary: This study investigates the migration and transformation processes of CuO NPs in lung lining fluid and the contradictory reports of redox reactions involving copper ions. The results reveal that PS can promote the release of ions from CuO NPs and induce lipid peroxidation, protein destabilization, and disruption of interfacial chemistry. This research provides new insight into the health risks of CuO NPs in the human body.

Summary: In this study, we report the structural characterization of copper complexes with both bridging and terminal alkenylidene ligands. The complexes were obtained by irradiation of Cu-I complexes with N-heterocyclic diazoolefin ligands. The isolation and structural characterization of the complex with a terminal alkenylidene ligand were achieved through crystalline matrix isolation and in crystallo photolysis at low temperature.

Summary: This research used a nickel coated conductive sponge as an adsorption interface to delay the particle aggregation caused by negative air ions. The aggregation of fine particles is caused by the transfer of electric charge and the oxidation characteristic of negative air ions, while the conductivity and roughness of the adsorption interface affect the migration direction and enrichment number of the particles.

Summary: Metal ions, especially Cu2+, play vital roles in various biochemical reactions in the human body and are essential for maintaining good health. This study investigates the interaction between Cu2+ and DNA using transmission electron microscopy (TEM) and in situ liquid-cell TEM. Results demonstrate that the binding of Cu2+ to DNA results in the bending of the DNA strand and provides a site for the nucleation and growth of copper crystals. The arrangement of the copper crystals along the curved DNA strand correlates with the guanine arrangement on the DNA sequence. This research provides a direct observation of the DNA-Cu2+ complex at the nanometer scale and contributes to further understanding the interaction mechanism, benefiting biomedical research.

Summary: Alzheimer's disease is the most common type of dementia in elderly individuals, and there is currently no effective disease-modifying treatment. Imbalance in brain metal ions has been found to be closely related to the onset and progression of Alzheimer's disease. Recent evidence suggests that interactions between brain metal ions and apolipoprotein E may be one of the mechanisms for neurodegeneration.

Summary: This study explores the synthesis, structure, and photophysics of a cyclic trinuclear copper(i) complex with iodine substitution, Cu-3[4-I-3,5-(CF3)(2)Pz](3), in comparison with previously reported complexes containing 4-Br/4-Cl groups. The crystal structure is stabilized by various supramolecular interactions, including Cu3MIDLINE HORIZONTAL ELLIPSISI and hydrogen/halogen bonding. Experimental and computational investigations are conducted to study the photophysical properties and supramolecular interactions of all three 4-halo complexes in relation to relativistic effects.

Summary: The present study systematically explored the effects of different divalent cations on alpha-Syn fibril formation. It was found that Zn2+ accelerated fibrillation and led to the formation of shorter fibrils, while Ca2+ ions resulted in longer fibrils. The fibrils formed in the presence of Cu2+, Ca2+, and Mg2+ were cytotoxic, while those formed in the presence of Zn2+ ions were nontoxic.

Summary: A new method for the preparation of surface tethered polymer films with pendant catechol functional groups is presented, achieved through a combination of polymerization and post-polymerization modification reactions. The resulting films demonstrate a high degree of selectivity towards specific metal ions, with reproducible loading levels after rinsing steps.

Summary: This study compares the impact of different plasma environments on the dynamics of damage formation in polycrystalline monolayer graphene films. Research shows that defect generation is slower at grain boundaries than within the grains due to preferential self-healing. Additionally, VUV photons enhance defect formation dynamics, while metastable species can both hinder and promote defect generation depending on the level of lattice disorder.

Summary: The article introduces an accurate, efficient, and transferable variational ansatz based on a combination of electron-positron geminal orbitals and a Jastrow factor. This ansatz explicitly includes the electron-positron correlations and is optimized using variational Monte Carlo. The approach is applied to calculate binding energies for various atomic and molecular systems, showing improved accuracy compared to previous calculations.

Summary: The Sharpless concept of copper(I) catalyzed azide-alkyne cycloaddition reaction, also known as click chemistry, has attracted attention in the synthesis of heterocyclic molecules. However, the full potential of this simple and efficient method in the synthesis of bidentate ligands for coordination chemistry has not been fully explored. This review focuses on the advancements in the application of click chemistry in the synthesis of bidentate ligands and the utilization of the metal complexes derived from these ligands in catalysis.

Summary: This study reports the solvothermal synthesis of a fluorescent metal-organic framework anchored with a dansyl sulfonamide dye, which exhibits high fluorescence emission properties, thermal and chemical stability, wide pH tolerance, and high BET surface area. The material shows ultra-fast and ultra-sensitive sensing properties towards Cu(ii) and 3-NTyr in various samples. Mechanistic investigations reveal complexometric interaction and FRET mechanism as the main reasons for the quenching of fluorescence intensity.

Summary: We demonstrate the importance of dynamical electron correlation effect in diabatic electron-exchange processes in molecular aggregates. A multireference perturbation theory with a large active space is performed using an efficient low-rank approximation. It is found that the direct term of diabatic couplings is not sufficient to explain the kinetic rates of electron-exchange processes, such as singlet fission, triplet-triplet annihilation, and triplet exciton transfer, but these processes are efficiently mediated by low-lying charge transfer states if the two molecules are in close proximity. It is also observed that regardless of the distance between the molecules, the direct term is significantly underestimated without the dynamical electron correlation.

It is confirmed that the use of local coordinates can significantly improve the efficiency of the method.
