Summary: Dinuclear copper complexes have been designed to selectively bind to neighboring phosphate moieties in DNA. Previous works have investigated the effects of these complexes on DNA through biophysical, biochemical, and cytotoxic analyses, with atomic force microscopy (AFM) being particularly valuable in assessing the macroscopic properties of the DNA strands. To gain a deeper understanding of these effects, cutting-edge preparation methods and scanning force microscopy under ultra-high vacuum (UHV) conditions were used to obtain submolecular resolution images. The mechanics and interactions of the DNA strands were analyzed at the single base pair level, including the formation of melting bubbles and the interaction of individual complex molecules.

Summary: Two dichloride-bridged dinuclear dysprosium(III) complexes based on salen ligands, [Dy(L-1)(mu-Cl)(thf)](2) and [Dy-2(L-2)(2)(mu-Cl)(2)(thf)(2)], were reported. Complex 2 showed clear slow relaxation of the magnetization due to the two short Dy-O-(PhO) bonds with an angle of approximately 143 degrees, while complex 1 exhibited slower relaxation due to an angle of around 90 degrees. The structural difference in the relative angles of the two O-(PhO)-Dy-O-(PhO) vectors in these complexes resulted in significant differences in their dipolar ground states, leading to open magnetic hysteresis in complex 3 and not in complex 2.

Summary: This work investigates the dynamic magnetic properties of a complex [(Cp-Ar3)(4)(Dy2Cl4K2)-Cl-III]& BULL;3.5(C7H8) synthesized using a tri-aryl-substituted cyclopentadienyl ligand (Cp-Ar3). The Dy(III)-metallocene weakly couples via K2Cl4 and exhibits slow relaxation of magnetization below 14.5 K under zero applied dc field through KD3 energy levels with an energy barrier of 136.9/133.7 cm(-1) at the Dy sites. The coordination of two chloride ions at each Dy centre leads to geometrical distortion and reduction of the single-ion axial anisotropy energy barrier.

Summary: The discovery of Single-Molecule Magnets in 1993 revolutionized the field of information storage by shrinking the size of bits to molecular levels. Despite initially operating at temperatures near absolute zero, collaboration between chemists and physicists have led to the development of materials that can operate above liquid nitrogen temperatures. The evolution of SMMs has involved the study of various routes towards high performance materials, with each route essential for understanding the quantum dynamics behind these molecules.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.

Summary: The development of the textile industry has raised concerns due to the contamination of drinking water by organic dyes, which pose a carcinogenic risk to humans. Nanomaterials, particularly semiconductors, have been utilized for photocatalytic degradation of dye pollutants. Various parameters, such as catalyst dosage, irradiation time, light sources, initial dye concentration, temperature, and pH, play significant roles in the degradation process. Different generations of photocatalytic nanomaterials, including single metal nanoparticles, binary and ternary metal oxides, as well as inert solid substrates with photocatalysts, have been employed for dye degradation.

Summary: Panax ginseng, as an ethnomedicinal plant, has therapeutic effects in traditional medicine. This study investigated the potential use of green-synthesized silver nanoparticles from Panax ginseng leaf extract for the treatment of lung carcinoma and heart protection against mitochondrial dysfunction and cardiac dysfunction in obese insulin-resistant rats. The silver nanoparticles showed spherical morphology with a size range of 12.11 to 43.33 nm. In vivo experiments demonstrated that the silver nanoparticles significantly improved metabolic parameters, heart rate variability, cardiac function, and cardiac mitochondrial function in the rats. This study suggests that silver nanoparticles derived from Panax ginseng have cardioprotective effects.

Summary: Nanozyme based sensors have been developed as an effective method for detecting harmful metal ions in water samples. In this study, a Co(II) based coordination polymer nanoparticle (Co-CP NP) was synthesized and utilized as a nanozyme to detect Fe(II) ions selectively. The Co-CP NP exhibited peroxido-reductase mimicking activity, and the detection limit for Fe(II) ions was found to be 0.66 μM. The catalytic action of the Co-CP NP was further analyzed using Michaelis-Menten kinetics, and the detection mechanism was elucidated through XPS and zeta potential analysis.
