The use of a fiber comb filter fabricated by a CO2 laser irradiation to improve the resolution of a ratiometric wavelength measurement system

, 2012
An edge filter based ratiometric wavelength measurement system is modelled and analysed in this paper. The results confirm that the noise of input signal and photodetectors limit the resolution of the wavelength measurement system.

Immunoinflammatory Mechanisms and Biocompatibility of Bioactive Dental Biomaterials: From Fundamental Insights to Clinical Translation

Advanced Healthcare Materials, EarlyView.
Surface‐host dialogue at the implant interface governs biological fate and osseointegration. Surface physicochemical properties of titanium (Ti) dental implants, including microgrooves, nanopatterns, nanotopography, roughness, and wettability, modulate the initial adsorption of proteins and the formation of a dynamic biointerface.
