Scanning Electron Microscopy of Hydrophilic Contact Lenses

Archives of Ophthalmology, 1972
Hydrated hydrophilic lenses of three different manufacturers (Griffen, Kontur, and Bausch and Lomb) were prepared for scanning electron microscopy utilizing air drying, freeze drying, and critical point drying techniques. Air dried lenses demonstrated artifacts analogous to those commonly seen in soft biological tissues when prepared in this manner ...

Eco‐Friendly Solvent System for Inkjet Deposition of Wide Bandgap Perovskite Solar Cells Enabling Tandem Integration

Advanced Science, EarlyView.
The fabrication of wide‐bandgap perovskite thin films via green solvents integrated with inkjet printing is developed. Controlled crystallization of the perovskite layer is achieved by optimizing ink formulation and additive engineering, enabling power conversion efficiencies above 17% for single junctions and 28% for perovskite/silicon tandem solar ...

Enhanced Antibacterial Properties of Lyotropic Liquid Crystalline Nanoparticles via Curvature Modulation

Advanced Science, EarlyView.
Lipid nanostructured particles with increasing negative Gaussian curvature progress from vesicles to P‐cubosomes and D‐cubosomes. This curvature hierarchy enhances interaction with bacterial membranes, promotes membrane remodeling and leakage, and potentiates daptomycin activity against MRSA.
