Keratoconus is a progressive corneal ectasia characterized by irregular astigmatism, leading to corneal scarring and decreased vision. Corneal cross-linking (CXL) is the standard treatment to halt disease progression, but its effectiveness in transepithelial (epithelium-on, epi-on) approaches is limited by the low permeability of the corneal epithelium to riboflavin (Rb). This study aimed to enhance transepithelial Rb penetration in bovine corneas using Rb-modified tannic acid-coated superparamagnetic iron oxide nanoparticles (Rb-TA-SPIONs) under an external magnetic field.

This study investigates steam washing (SW) as an innovative pretreatment for municipal solid waste incineration fly ash (MSWI-FA) dechlorination, useful for a more effective stabilization in cementitious matrix. By using a detailed analytical approach (XRPD, XRF, ICP-MS, IRMS, SEM) and geochemical modeling, great focus is dedicated on pollutant leaching reduction and changes in ash physicochemical characteristics as a function of exposure time. The research demonstrates that SW removes up to 70 % cadmium, 17 % zinc, and 10 % lead, primarily by dissolving the soluble and carbonate/hydroxide fractions and promoting the reprecipitation and adsorption of heavy metals into more stable compounds.

Carbon monoxide (CO) gas therapy, as an emerging therapeutic strategy, is promising in tumor treatment. However, the development of a red or near-infrared light-driven efficient CO release strategy is still challenging due to the limited physicochemical characteristics of the photoactivated carbon monoxide-releasing molecules (photoCORMs). Here, we discovered a novel photorelease CO mechanism that involved dual pathways of CO release via photosensitization.
