March 2025
Department of Cardiology, University of Medicine and Pharmacy, 300041 Timișoara, Romania.
Background/objectives: Transepithelial accelerated corneal crosslinking (TE-ACXL) is a minimally invasive approach for stabilizing progressive keratoconus while preserving the corneal epithelium. This study aims to evaluate changes in visual acuity, refractive error, and corneal parameters before and six months after TE-ACXL.
Methods: A retrospective analysis was conducted on 30 eyes from 20 patients who underwent TE-ACXL between May 2021 and June 2023.

The molecular design of new compounds with enhanced third-order nonlinear optical (NLO) applications is an important research topic in the area of functional materials. The present study describes a new 3D metal-organic framework [Zn(μ-bta)(μ-ata)] (abbreviated as NH-Zn-MUM-6), generated solvothermally from a multicomponent system composed of zinc(II) ions and 2-aminoterephthalic acid (Hata) and 1H-benzotriazole (Hbta) as linkers. Apart from an intricate porous structure with a seh-4,6- topology, this MOF features good thermal stability and exceptional NLO characteristics.

Oxide submicrospheres with a high refractive index are essential for enhancing scattering and manipulating light transmission at submicrometer scale in photonic applications. However, achieving precise control over the diameter and monodispersity of transition metal oxide submicrospheres remains challenging, due to the unclear formation mechanism and lack of effective synthesis strategy. Here, a nonclassical mechanism of oligomer aggregation for controllable synthesis of monodispersed ZrO submicrospheres (ZS) with mean diameters ranging from 0.
