It was found that PbS quantum dots with the FA ligand have higher mobility and improved optical absorption compared to quantum dots with the Cl ligand. The differences can be explained by the features of the intermediate electronic structure and further used to increase the efficiency of solar cells.

Study of the density of states and optical absorption profile for PbS quantum dots with Cl and Fa ligands

It was found that PbS quantum dots with the FA ligand have higher mobility and improved optical absorption compared to quantum dots with the Cl ligand. The differences can be explained by the features of the intermediate electronic structure and further used to increase the efficiency of solar cells.

Cobalt nanostructures possess unique magnetic, electrical, and chemical properties, making them valuable for applications in electronics, energy storage, spintronics, and superconducting devices. They enable efficient data storage, low-energy spin manipulation, and improved device performance. This work investigates the magnetic behavior of thin cobalt films with different thicknesses under various magnetic fields.

The elastic modulus of transformer steel sheets is studied using the EBSD and DMA methods at various manufacturing stages. A non-uniform distribution of the elastic modulus across the thickness of the sheets along with its anisotropic behavior is discussed in terms of texture evolution along the production chain.

Estimation of elastic modulus anisotropy in grain-oriented electrical steel using EBSD and DMA methods

The elastic modulus of transformer steel sheets is studied using the EBSD and DMA methods at various manufacturing stages. A non-uniform distribution of the elastic modulus across the thickness of the sheets along with its anisotropic behavior is discussed in terms of texture evolution along the production chain.

The study investigates the kinetics of self-healing of the main crack in WC-Co hard alloy. After an eight-hour holding near the sintering temperature the total crack length was reduced by 30% and the maximum crack width capable to self-healing through liquid-phase recovery was approximately 50 μm.

A direct comparison between the model and commercial aluminum alloy reveals that dispersoids in the latter decisively accelerate grain refinement during high‑temperature deformation. The study discusses the decoupling of specific processes — enhanced strain localization and suppressed recovery — through which this acceleration occurs.

Hybrid Al-5083 MMCs reinforced with SiC, Mg, and Sr were fabricated using stir casting and characterized using optical microscopy, SEM, and EDS. The image-based microstructural features were correlated with tensile, flexural, impact, and wear properties to identify the optimal reinforcement level.
