Fluocinolone acetonide implant (FAci) one month after dexamethasone implant (DEXi) for chronic diabetic macular edema: 1-year results.

Purpose: To evaluate the safety and efficacy of FACi injected 1month after the last DEXi injection in pseudophakic patients without ocular hypertension who required frequent DEXi injections (<6months).

Patients And Methods: This was a prospective study including pseudophakic patients with chronic diabetic macular edema (DME) previously treated with DEXi without secondary ocular hypertension. All patients received DEXi followed by FAci one month later.

EBSD and TKD analyses using inverted contrast Kikuchi diffraction patterns and alternative measurement geometries.

Electron backscatter diffraction (EBSD) patterns can exhibit Kikuchi bands with inverted contrast due to anomalous absorption. This can be observed, for example, on samples with nanoscale topography, in case of a low tilt backscattering geometry, or for transmission Kikuchi diffraction (TKD) on thicker samples. Three examples are discussed where contrast-inverted physics-based simulated master patterns have been applied to find the correct crystal orientation.

Density functional theory study of Au-fcc/Ge and Au-hcp/Ge interfaces.

In recent years, nanostructures with hexagonal polytypes of gold have been synthesised, opening new possibilities in nanoscience and nanotechnology. As bulk gold crystallizes in the fcc phase, surface effects can play an important role in stabilizing hexagonal gold nanostructures. Here, we investigate several heterostructures with Ge substrates, including the fcc and hcp phases of gold that have been observed experimentally.

[Creation and evaluation of a triage survey for ophthalmology emergencies].

Purpose: The demand for eye care is growing continuously. We created a triage survey system, based on categories of severity, to optimize first line patient care in an ophthalmology emergency department.

Methods: This cross-sectional study was carried out from July 7th, 2021 to October 10th, 2021.

Quantifying colors at micrometer scale by colorimetric microscopy (C-Microscopy) approach.

The color is the primal property of the objects around us and is direct manifestation of light-matter interactions. The color information is used in many different fields of science, technology and industry to investigate material properties or for identification of concentrations of substances. Usually the color information is used as a global parameter in a macro scale.
