A number of biological and physical stimuli have been evaluated as inducers of pseudopterosin biosynthesis in the sea whip Pseudopterogorgia elisabethae. Data indicate that the production of pseudopterosins can be significantly increased in response to high levels of predation by the mollusk Cyphoma...

Abstract: The color changes associated with the aggregation of metal nanoparticles has led to the development of colorimetric-based assays for a variety of target species. We have examined both silver- and gold-based nanoparticles in order to establish whether either metal exhibits optimal character...

Poly[oxymethylene-(oxyethylene)] has been inserted in the gallery space Of MoS2 by using the exfoliation/re-stacking properties of LiMoS2. The resulting intercalation compound shows enhanced electronic conductivity due to a structural transformation of the MoS2 framework. The material was also chara...

In this paper we report on the electrical characterization of conductive polyaniline and its derivatives. Conductivity measurements were also performed on the intercalated phases formed by the encapsulation of the polymers into layered molybdenum disulfide. These measurements were performed using th...

This report describes a series of experiments designed to determine if terpene biosynthesis is inducible in two families of marine terpenes, pseudopterosins from the gorgonian coral Pseudopterogorgia elisabethae and fuscol from Eunicea fusca. Since we have recently shown that terpene biosynthesis is...

Abstract: Laser flash photolyses of 2-, 3-, and 4-diazoacetylpyridines 8 give the corresponding pyridylketenes 7 formed by Wolff rearrangements, as observed by time-resolved infrared spectroscopy, with ketenyl absorptions at 2127, 2125, and 2128 cm-1, respectively. Photolysis of 2-, 3-, and 4-8 in C...

Abstract: The title ketene 2 has been generated by laser flash photolysis and observed in solution for the first time, using time-resolved infrared spectroscopy. The kinetics of the reactivity of 2 with H2O, MeOH, and Et2NH with relative reactivities of 1.0, 2.0, and 73 have been measured. These are...

The new thrusts in molecular logic are gathered together in this short review, while paying attention to the seeds from which these developments have arisen. The original demonstration of a few basic logic operations has now been extended to cover many of the one- and two-input varieties and even so...

The conductivity of an ordered polyphosphazene Na+-montmorillonite composite has been measured perpendicular (sigma(para)) and parallel (sigma(perp)) to the montmorillonite layers, and the sigma(para)/sigma(perp) is about 100. The temperature dependence of the conductivity is consistent with a coupl...

Abstract: This work describes the fluorescence enhancement of the probes 2,6- and 1,8-ANS via complexation with the macrocyclic host cucurbit[7]uril (Q7). The association of these two guests with the Q7 host has been studied using fluorescence, 1H NMR spectroscopy, and molecular modeling. In the cas...

Intercalation compounds of pyrene and 8-anilino-1-naphthalenesulfonic acid into MoS2 have been synthesized and characterized. This was achieved by using the exfoliation/re-stacking properties of LiMoS2. The degree of intercalation was found to be dependent on the amount of guest species used, the re...
