AULACOSEIRA SKVORTZOWII SP. NOV. (BACILLARIOPHYTA), A POORLY UNDERSTOOD DIATOM FROM LAKE BAIKAL, RUSSIA1

Mark B. Edlund、Eugene F. Stoermer、Christine M. Taylor1996-02-01Journal of Phycology

ABSTRACT Aulacoseira skvortzowii sp. nov. is a diatom taxon present in modern plankton assemblages and sedimentary deposits from Lake Baikal, Russia. It has been previously reported as A. islandica (O. Müll.) Simonsen, A. islandica ssp. helvetica (O. Müll.) Simonsen, a sporangial frustule of A. baicalensis (K. Meyer)…

Effect of the Composition of Polypyrrole Substrate on the Electrodeposition of Copper and Nickel

Maria Hepel、Yi‐Ming Chen、Richard A. Stephenson1996-02-01Journal of The Electrochemical Society

Electrodeposition of copper and nickel on a variety of substrates including conductive polymer films with two different compositions has been studied. The enhancement of the copper and nickel electrodeposition rate was observed for composite polypyrrole films with cation‐exchange properties in comparison to undoped po…

Anionic polymerization of oxirane in the presence of the polyiminophosphazene base t‐Bu‐P4

Beate Eßwein、Norbert M. Steidl、Martin Möller1996-02-01Macromolecular Rapid Communications

Abstract The use of the polyiminophosphazene base t ‐Bu‐P 4 (1) for the anionic polymerization of ethylene oxide is described. Polymerization initiated by a monoalkoxide of the protonated base leads to well‐defined poly(ethylene oxide)s with low polydispersity ( M w / M n ≈ 1.1). Furthermore, graft copolymers of poly[…

A single source approach to the synthesis of CdSe nanocrystallites

Tito Trindade、Paul O’Brien1996-02-01Advanced Materials

Synthetic routes to semiconductor nanocrystallites have become of particular interest since nanoparticle devices have been constructed. The route reported here for CdSe uses a single source in tri‐ n ‐octylphosphine oxide instead of the hazardous metal alkyls conventionally employed. The characterization of the nanocr…
