Liquid Phase Backscattered Scanning Electron Microscopy of Bacillus subtilis Spores

Small Methods, EarlyView.
Graphene encapsulation enables liquid‐phase BSE‐SEM to visualize subsurface architecture of whole, hydrated Bacillus subtilis spores without staining. This approach is applied to visualize dormant spores and subsequent structural changes during spore germination, while imaging across a range of beam energies and Monte Carlo simulations provide a ...

The Effect of Viscosity of PDMS Based Silicone-Oil Tamponade Agents on the Movement Relative to the Eye Wall during Eye Movements

i-Perception, 2011
Silicone oil tamponade is used as vitreous substitute to treat complicated retinal diseases. It provides support to the retina and acts against contraction of the retina and as such plays a vital role in preventing eyes from certain blindness.

Artificial vitreous replacements

, 2003
Vitreoretinal pathologies remain the significant leading cause of blindness, after cataract, throughout the world. Biomaterials as a whole, and vitreous substitutes in particular, have had a major role to play in vitreoretinal surgery.

Cyclic GMP in the pig vitreous and retina after experimental retinal detachment [PDF]

, 2008
Purpose: Earlier studies have revealed a decreased level of cGMP in vitreous fluid obtained from patients with a retinal detachment. To further investigate this phenomenon, we developed an experimental retinal detachment model in pigs.

Revealing the Atomic‐Scale Structure of the Copper–Sulfuric Acid Interface

Small Methods, EarlyView.
How do acids interact with metallic surfaces? Using a multidisciplinary approach of electrodeposition and 3D‐printing, a novel approach of micro‐corrosion cells enables cryogenic atom probe tomography at the liquid‐solid interface of dilute sulfuric acid in contact with copper at different time and thermal conditions. ABSTRACT Corrosion originates from
