In contrast to glass, the use of polymeric substrates limits the temperature of the deposition processes. Mechanical and thermal properties of polymer substrates differ from those of inorganic thin-film materials. In addition, different polymeric substrates present different chemical and surface ...
As for the radar "track", a blip appearing for only "a few sweeps" could be almost anything: noise, AP, or possibly a real target flying near the lower limits of the radar beam. 1212-B. Tillamook, Ore., 13-14 March 1967, 2230-0008 LST. Weather: clear with "stars plainly visible...
Optical microscopy has emerged as a key driver of fundamental research since it provides the ability to probe into imperceptible structures in the biomedic
third harmonic generation and multiphoton excitation fluorescence microscopy, other emerging nonlinear imaging modalities are described and several linear optical microscopy techniques are reviewed in order to clearly describe their capabilities and to highlight the advantages of nonlinear microscopy. log in vi...
The absorption loss of silica limits the SSFSs ability to achieve wavelengths longer than 2 μm. However, light sources above 2 μm are in the eye-safe range and have important applications, such as medical treatment. Bi et al., using a tellurite MOF, obtained the wavelength shift range ...
The voltammetric detection implemented in microfluidic devices, compared to stationary analysis, is associated with improved detection limits, where the faradic current increases due to the increased transport rate of the analyte to the electrode surface [147] for microfluidic applications. Contactless condu...
This limits this mechanism of extension of the homogeneous luminous length as well [33]. In order to generate a sidelight emission, various sidelight activation methods exist, which differ in terms of the underlying physical effect on the one hand, and the actual production process on the other...
Moreover, this polymer is also characterized by being resistant to impacts and vibrations and having lower density (1,195 kg.m−3) and higher elastic deformation limits (10%) [9]. For POF, the mechanical strength depends on the composition, drawing process, presence of dopants and geometry...
Waveguides made of poly-methyl-methacrylate (PMMA) play a major role in the homogeneous distribution of display backlights as a matrix for solid-state dye lasers and polymer optical fibers (POFs). PMMA is favored because of its transparency in the visibl
