Fiber monomode

The biberty (Fig. 10), a monomode microwave reactor for automated SPPS, was recently introduced by the CEM Corporation [153]. Although this instrument was originally developed for SPPS, it also allows for a broader scale of solid-phase applications. The solid-phase vial is equipped with a polypropylene frit and cap at one end (the entire assembly fitting into the standard 10 mb CEM reaction vessel) to allow the processing of 0.1 to 1.0 mmol quantities of resin attached substrates. An integrated fiber optic probe provides...

Both polymers 10 and 11 are soluble in common organic solvents, melt without decomposition, and can be drawn into the fibers. Molecular weights of the polymers 10 and 11, determined by gel permeation chromatography with tetrahydrofuran as the eluant after purification by reprecipitation from benzene-ethanol, showed a broad monomodal molecular weight distribution. The degree of polymerization depends on particle size of sodium metal. Polymers with molecular weights of 23,000-34,000 are always obtained, if fine sodium particles are used.

The optical flber SPR is the smaller device of this technology, allowing the use of this technique in distant locations. Sensors based on monomode and multimode optical flbers have been reported [23,24]. The cladding of the flber is partially removed and a gold layer is deposited symmetrically around the exposed fiber core. This type of fabrication limits the interaction area to a... 

The same restriction applies to all-polymer fibers. Modern, all-glass fibers may have losses of less than 0.5 dB km at a wavelength of 1.3 pm . Typical diameters of the core and the cladded fiber are 50 and 125 pm, respectively, but there is a trend to switch over to so-called monomode fibers which have cores with a diameter of 5-10 pm. 

Dynamic light scattering measurements were made with a monomode-fiber compact goniometer system (ALV) and an argon-ion laser (Spectra Physics, Stabilite 2016).
