A three-dimensional model to describe complete human corneal oxygenation during contact lens wear. [PDF]
J Biomed Mater Res B Appl Biomater, 2023 A full 3D axisymmetric and time‐dependent model of the cornea‐lens system has been numerically solved to determine the oxygen flux and consumption in each part of the cornea. We apply our model to different lenses currently usted on the market, showing the importance of detailed geometry in the modelling of these systems. Abstract We perform a novel 3D

A new three-dimensional model to describe human corneal oxygenation during contact lenses wear. [PDF]
Ophthalmic Physiol OptAbstract Purpose This three‐dimensional study investigated how different contact lens materials affect oxygen levels in the cornea. Specifically, it measured oxygen tension, flux and consumption in the epithelium, stroma and endothelium when exposed to various contact lenses.

A Machine Learning Approach to Derive Aerosol Properties from All-Sky Camera Imagery
Remote Sensing, 2023 We propose a methodology to derive the aerosol optical depth (AOD) and Angstrom exponent (AE) from calibrated images of an all-sky camera. It is based on a machine learning (ML) approach that establishes a relationship between AERONET measurements of AOD

Parametric study of particles homogenization in cold-flow riser reactors
International Journal of Thermofluids, 2021 Fluid Catalytic cracking (FCC) process are frequently used for the upgrading of heavy crude oil into more valuable products. Traditionally, the FCC process occurs in a riser reactor, where both vaporised hydrocarbon feed-stock and solid catalyst flow in ...

Advanced Optical Materials, Volume 11, Issue 20, October 18, 2023., 2023 The addition of a large amount of β‐(1,4) cellulose oligosaccharide (20 wt.%) to metal halide perovskites (MHPs) layers causes a reduction of the perovskite grains to the nanometer scale (30–40 nm) together with a 14‐fold increase of the photoluminescence quantum yield (PLQY).
