A method is described to prepare poly(isoprene-b-(isoprene-co-styrene+-b-styrene) three-block copolymers in which the interphase thickness is varied by the molecular weight of a random copolymer center block. The interphase width was determined by electron microscopy, small angle X-ray scattering an
Near-infrared spectroscopy was used to monitor the phase conversion for two solvatomorphs of caffeine, an anhydrous form and a nonstoichiometric hydrate, as a function of time, temperature, and relative humidity. The transformation kinetics between these caffeine forms was determined to increase wit
## Abstract We study the pinning and depinning behavior of interfaces immersed in a heterogeneous medium. For a continuum elasticicity model of the martensitic phase transformation, we numerically estimate the critical depinning stress of a phase boundary intersecting a nonβtransforming inclusion i
frequency changed, by including the series resistance value (0.8β) in the model, by a maximum of 36 MHz for the 0Β°angle. For the chosen varactor diodes, the electrical shift in the bandstop frequency of the filter, shown in Figure 3, is 150 to 200 MHz (depending on β°). This shift can be increased b
