Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells

Advanced Materials, EarlyView.
This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

Advanced Materials, EarlyView.
This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...

The thickness of the tear film

Current Eye Research, 2004
Measurements of the thickness of the pre-corneal tear film, pre-lens tear film, post-lens tear film, and the lipid layer on the surface of the tear film are summarized. Spatial and temporal variations in tear film thickness are described. Theoretical predictions of tear film thickness are discussed.

Characterization of thin-film thickness

Metrologia, 2014
Analysis methods and instrumentation for obtaining optical parameters and thickness profiles of thin-film samples from spectrophotometric and ellipsometric measurements are presented. Measured samples include thermally grown and evaporated SiO2 on a silicon substrate and a polymer photoresist layer on silicon.

The limiting thickness of protein films

Journal of Colloid and Interface Science, 1967
Abstract The thinning of microscopic lamellae formed from solutions of bovine serum albumen and bovine γ-globulin has been studied by a modification of the method of Scheludko. Provided the surfaces were cleaned to remove coagulated material, fairly persistent, uniform films were obtained in certain pH ranges.

Film thickness of disclosing wax

The Journal of Prosthetic Dentistry, 1983
lhe fitting of a removable partial denture framework or a metal crown against tooth structure can be facilitated by the aid of disclosing wax.’ This soft wax material is placed on surfaces of restorations that contact the teeth. After insertion and removal of the restorations, interferences will be visible as bright spots (Figs. 1 and 2).

Lonsdaleite Films with Nanometer Thickness

The Journal of Physical Chemistry Letters, 2014
We investigate the properties of potentially the stiffest quasi-2-D films with lonsdaleite structure. Using a combination of ab initio and empirical potential approaches, we analyze the elastic properties of lonsdaleite films in both elastic and inelastic regimes and compare them with graphene and diamond films.

Thickness Distribution of Evaporated Films

Optical Interference Coatings, 1988
In order to set up a vacuum chamber for coating a number of large parts, or perhaps a large number of small parts, it is of importance to know the emission characteristics (source function) of the evaporation source.
