Synthesis of 1,2,3,4-tetrahydro-1,2-dimethylidenenaphthalene: A reactive s-cis-butadiene undergoing highly chemo- and regioselective cyclodimerization

1,2,3,4-Tetrahydro-1,2-dimethylidenenaphtlhalene 11 has been derived in three steps from tetralone. In the condensed state and at - 80degrees, it undergoes a highly chemo- and regioselective cyclodimerization to give 3.3',4,4'-tetrahydro-2-methylidenespiro ...

In-situ monitoring of GaN growth by hydride vapor phase epitaxy

Jean-François Carlin, Marc Ilegems, Denis Martin

In-situ reflectivity measurements of the growth surface during deposition in a Hydride Vapor Phase Epitaxy system are presented. The GaN growth rate increases linearly with the HCl flow and increases monotonically with the ammonia flow. Following the repla ...

Calcium-Iron(III)-Doped Alginate Gel Beads for Sorption of Arsenate and Selenate

Janet Gordon Hering

Systems and methods for removing oxyanionic contaminants, such as arsenate (As(V)) and selenite (Se(IV)), from polluted water. The system utilizes calcium alginate which has been doped with ferric iron. The system is operated as either a batch-type or cont ...

Ability of polycyclic aromatic hydrocarbons to induce 7-ethoxyresorufin-o-deethylase activity in a trout liver cell line

Kristin Schirmer

Along with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), 24 unsubstituted polycyclic aromatic hydrocarbons (PAHs) were evaluated for their ability to induce 7-ethoxyresorufin-o-deethylase (EROD) activity in the rainbow trout liver cell line RTL-W1. When the ...

Preatomization behavior of palladium in electrothermal atomic-absorption spectrometry

Under certain exptl. conditions-short pyrolysis times, fast heating rates and presence of reducing agent-increasing vaporization temps. led to decreasing losses of Pd as the initial mass was increased between 0.3 and 5.0 ng. When Pd is introduced into the ...

The effect of ashing on cells: Spectromicroscopy of physiological elements

Giorgio Margaritondo

We analyzed the effects of cold oxygen plasma ashing of neurobiological specimens on different elements with synchrotron spectromicroscopy. Our results demonstrate that while carbon is almost completely removed, phosphorus, calcium, potassium, sulfur, and, ...

Electrochemical properties of Ti/SnO2-Sb2O5 electrodes prepared by the spray pyrolysis technique

Christos Comninellis

Cyclic voltammetry for the ferri-ferrocyanide redox couple was used to study the Ti/SnO2-Sb2O5 electrode prepd. by spray-pyrolysis under different conditions. Increasing the prepn. temp. and the duration of coating deposition results in a decrease of ip an ...
