Protein Adsorption at Nanorough Titanium Oxide Surfaces: The Importance of Surface Statistical Parameters beyond Surface Roughness

open access: yesNanomaterials, 2021
The nanoscale surface topography of biomaterials can have strong effects on protein adsorption. While there are numerous surface statistical parameters for the characterization of nanorough surfaces, none of them alone provides a complete description of ...

Multiple reflections in an optical retarder investigated by spectroscopic transmission ellipsometry [PDF]

open access: yes, 1987
The response of the ellipsometric parameters as a function of wavelength has been derived for an optical retarder. Experimental results in the wavelength region 400–1000 nm are given, these are in agreement with the derived ...

Transient dielectric function dynamics driven by coherent phonons in Bismuth crystal

open access: yesJournal of the European Optical Society-Rapid Publications
In this study, we investigate the ultrafast transient dynamics of the dielectric function in bismuth crystal, excited by femtosecond laser pulses and modulated by coherent phonons. The primary aim is to understand the influence of the coherent A1g phonon

Glass transition in Ultrathin Polymer Films : A Thermal Expansion Study [PDF]

open access: yes, 2005
Glass transition process gets affected in ultrathin films having thickness comparable to the size of the molecules. We observe systematic broadening of glass transition temperature (Tg) as the thickness of the polymer film reduces below the radius of ...

Vertical-Objective-Based Ellipsometric Microscope for Real-Time Observation of nm-Thick Lubricant Films

open access: yesTribology Online, 2012
The vertical-objective-based ellipsometric microscope (VEM) is expected to be a useful method for clarifying the lubrication phenomena that uses thin liquid lubricants, especially the lubricant for hard disk drives (HDDs). Although the feasibility of VEM
