Significant differences between specular microscopy and corneal bank endothelial cell counts – a pilot study

Acta ophthalmologica, 2019
It was shown recently that endothelial cell count performed by cornea banks overestimates the real number of endothelial cells. The aim of this study was to investigate the internal quality of preclinical ECD in human donor corneas using two widely used ...

Diffuse neutron reflectivity and AFM study of interface morphology of an electro-deposited Ni/Cu film

, 2008
We present a detailed study of the interface morphology of an electro-deposited (ED) Ni/Cu bilayer film by using off-specular (diffuse) neutron reflectivity technique and Atomic Force Microscopy (AFM). The Ni/Cu bilayer has been electro-deposited on seed

Kinetic Regimes of Hydrogen Absorption in Thin Films

Advanced Functional Materials, EarlyView.
Knowledge of the hydrogen incorporation mechanisms in thin layers in relation to the amount absorbed is essential to design coatings and devices compatible with hydrogen‐based technologies. A combination of simultaneous in situ methods gives detailed insight into the hydrogenation of a prototypical hydrogen absorber layer in a time‐dependent manner ...

CLINICAL SPECULAR MICROSCOPY: THE AUSTRALIAN EXPERIENCE [PDF]

Australian Journal of Opthalmology, 1984
AbstractIt is almost one year since the Corneal Diseases Unit of The Royal Victorian Eye and Ear Hospital began preliminary evaluation of the Pocklington Keeler‐Konan Wide‐Field Specular Microscope. With this instrument, approximately one square millimetre of living human corneal endothelial cells can be observed and photographed. This relatively large

Tracing Sub‐Monolayer Contamination on Wafer‐Scale 2D Materials

Advanced Functional Materials, EarlyView.
Sub‐monolayer adventitious carbon contamination limits the performance and reproducibility of 2D material‐based devices. This study demonstrates scanning helium microscopy (SHeM) as a non‐destructive, ultra‐sensitive tool for wafer‐scale imaging of surface cleanliness.

Real-space study of the growth of magnesium on ruthenium

, 2013
The growth of magnesium on ruthenium has been studied by low-energy electron microscopy (LEEM) and scanning tunneling microscopy (STM). In LEEM, a layer-by-layer growth is observed except in the first monolayer, where the completion of the first layer in

Reflection electron energy loss spectroscopy during initial stages of Ge growth on Si by molecular beam epitaxy [PDF]

, 1991
Using a conventional reflection high-energy electron diffraction gun together with an electron energy loss spectrometer, we have combined in situ measurements of inelastic scattering intensities from Si L2,3 and Ge L2,3 core losses with reflection ...

Coating Artificial Spider Silk Fiber with Magnetic FeCo: An Effective Strategy for Creating a Flexible Magneto‐Responsive Material

Advanced Functional Materials, EarlyView.
An original method is presented for producing artificial spider silk fibers with magnetic and magnetomechanical responsiveness, which consists in coating them with a nanometer‐thick layer of FeCo alloy by sputtering deposition. The challenge of combining organic materials and inorganic magnetic nanostructures is addressed, thus taking a step forward ...

Light scattering from self-affine fractal silver surfaces with nanoscale cutoff: Far-field and near-field calculations

, 2001
We study the light scattered from randomly rough, one-dimensional self-affine fractal silver surfaces with nanoscale lower cutoff, illuminated by s- or p-polarized Gaussian beams a few microns wide.
