The general approach for describing and designing complex hierarchical icosahedral structures is discussed. Structural models of icosahedral carbon nanoparticles in which the local arrangement of atoms is virtually identical to that in diamond are derived. It is shown that icosahedral diamond-like particles can be transformed into onion-like shell structures (and vice versa) by the consecutive smoothing (puckering) of atomic networks without disturbance of their topological integrity. The possibility of coherent coexistence of icosahedral diamond-like core with onion shells is shown.

Clinical Relevance: Vitreous floaters have been associated with depressive and anxiety symptoms. However, there is a scarcity in the literature regarding the possible impact of vitreous flashes on the psychological status of the patients.

Background: Photopsias and vitreous floaters frequently co-exist.

Coherent phase transformations in interstitial solid solutions or intercalation compounds with a miscibility gap are of practical relevance for energy storage materials and specifically for metal hydride or lithium-ion compound nanoparticles. Different conclusions on the size-dependence of the transformation conditions are reached by modeling or theory focusing on the impact of either one (internal, solid-state-) critical-point wetting of the nanoparticle surface or coherency constraints from solute-saturated surface layers. We report a hybrid numerical approach, combining atomistic grand canonical Monte Carlo simulation with a continuum mechanics analysis of coherency stress and modeling simultaneously wetting and mechanical constraints.

Hydrogen storage in intermetallic compounds, known as solid-state storage, relies on a phase change by the metal alloy. This phenomenon causes a violent change in volume at the crystalline scale, inducing a change of volume for the millimetric particles and, with time, important stresses on the tanks. It is thus necessary to know the mechanical behavior of the material to report these phenomena and improve the tanks' reliability.

Article Synopsis
  • Neointimal coverage and stent apposition are critical for improving percutaneous coronary interventions (PCI), but current algorithms struggle with automating the analysis of diverse stent types and preselecting necessary segments.
  • This study introduces TriVOCTNet, a multi-task deep learning model designed to automate the classification, lumen segmentation, and stent strut segmentation in IVOCT images, all within one efficient network.
  • TriVOCTNet demonstrated impressive accuracy with high classification rates and precise segmentation outputs, indicating its potential for enhancing clinical practices in PCI procedures.

Ion channels are protein structures that facilitate the selective passage of ions across the membrane cells of living organisms. They are known for their high conductance and high selectivity. The precise mechanism between these two seemingly contradicting features is not yet firmly established.
