A synthetic route is described for collagen-like polypeptides constructed from O-phospho-L-hydroxyproline [Hyp(PO(3)H(2))] residues. Using the synthetic polypeptides and a natural protein, gelatin, fine fibers and their network structures (ESNWs) were prepared via electrospinning. The composite ESNWs can induce the mineralization of calcium phosphate. The phosphoryl groups of the Hyp(PO(3)H(2)) residues affect both the crystalline phase and amount of the calcium phosphate, depending on the chemical structure in the repeating sequence. The composite ESNWs can be developed as a biocompatible replacement of the extracellular matrix of hard tissues, and thus can be applied as dental materials for restoration of dental cavities or as a sealant for pits and fissures.
In this paper we propose an application of microstrip line for a single-turn pickup coil in the thin-film permeance meters. This coil has two electric ports with one terminated into 50 51. It is free from LC resonance up to a few GHz because the microstrip line does not resonates and because the stray capacitance between the pickup coil and the driving sheets is small as compared with the conventional figure-8 coil. We measured the thin film permeance up to 700 MHz which is the upper frequency limit of the driving sheets used. The proposed coil has a potential to measure thin-film permeances over the wide range from 1 MHz up to a few GHz.
Apart from transparent conductors, the demand for nontransparent black insulators in the electronic display industry is significant. The development of these dark insulators requires sophisticated material designs. This study shows that narrow‐gap‐oxide‐based nanoscale cermets with nonequilibrium phases which decompose into metal and oxide phases have both the insulative character and a stronger and less‐dispersive absorption than graphite throughout the visible range. Herein, the cases of pulsed‐laser‐deposition‐derived Ag–Fe2O3 and Cu–Bi2O3 systems are shown. The combination of the interband absorption of the narrow‐gap oxides and the plasmonic absorption of the metals provides strong optical absorption throughout the visible range. Because they create diffusion at the edge of the interband absorption and the peaks of the plasmonic absorption, the nonequilibrium phases make the absorption less dispersive. By preventing the mutual contact of the metal grains, they also make the cermets electrically insulative. This new approach has the potential to produce excellent black and insulating optical coatings using a variety of combinations of metals and ceramics for touch panel displays.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
