Mediating effects of ferric chelate compounds in microbial fuel cells

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1983
Abstract The performance of bio-fuel cells containing Escherichia coli , glucose and a series of ferric chelate reagents was studies. The measured coulombic outputs indicate that the most of the compounds work effectively as electron-transfer mediators in the fuel cells.

Electron-microscopy study of the ferric chloride/graphite compound

Carbon, 1967
Abstract The direction of the Burgers vector of the dislocations bounding the intercalated ferric chloride layers in the interlamellar compound of graphite and ferric chloride has been determined by extinction of the contrast and is found to be perpendicular to the c -planes. From this result the conclusion is drawn that graphite preserves its a b

Magnetic properties of some high spin ferric heme compounds

Biochimica et Biophysica Acta (BBA) - General Subjects, 1971
Abstract Using a crystal field model, and generalized expressions for magnetic properties, the magnetization, susceptibilities and effective magnetic moments of a series of high spin heme compounds whose zero-field characteristics are known have been calculated as a function of both magnetic field strength and temperature.

The EFG in oxonium ferric orthophosphate hydrate and related compounds

Hyperfine Interactions, 1988
The point cherge model was used to interpret the small quadrupole spilting of Fe3H15(PO4)8·5H2O by comparing it with related phosphates of known structure. The approximation is sufficient as long as octahedrally coordinated compounds are compared for which Vzz and η do not change their signs.

Chlorinated Aromatic Compounds in a Thermal Process Promoted by Oxychlorination of Ferric Chloride

Environmental Science & Technology, 2010
The relationship between the formation of chlorinated aromatic (aromatic-Cl) compounds and ferric chloride in the solid phase during a thermal process motivated us to study the chemical characteristics of iron in a model solid sample, a mixture of FeCl(3) x 6H(2)O, activated carbon, and boron nitride, with increasing temperature.

Ferric(III) Chloride Promoted Electrophilic Thiocyanation of Aromatic and Heteroaromatic Compounds.

ChemInform, 2005
Indoles, oxindoles and aromatic amino compounds undergo smooth thiocyanation with ammonium thiocyanate in the presence of anhydrous FeCl 3 in dichloromethane under mild conditions to afford the corresponding 3-indolyl and4-aryl thiocyanates, respectively, in high yields with excellent selectivity. The use of ferric chloride makes it quite simple, more

Ferric chloride‐Graphite Intercalation Compounds as Anode Materials for Li‐ion Batteries

ChemSusChem, 2013
AbstractFerric chloride‐graphite intercalation compounds (FeCl3–GICs) with stage 1 and stage 2 structures were synthesized by reacting FeCl3 and expanded graphite (EG) in air in a stainless‐steel autoclave. As rechargeable Li‐ion batteries, these FeCl3–GICs exhibit high capacity, excellent cycling stability, and superior rate capability, which could be

Are ferric chloride intercalated graphite compounds air stable?

Synthetic Metals, 1983
Abstract Mossbauer spectroscopy has been used as a tool to analyze the effect of long term exposure to air on ferric chloride intercalated graphite samples. After periods of about a year three phenomena occur in sequence: there is a migration of some FeCl 3 from the sample, some of the FeCl 3 is converted into (FeCl 4 ) − and finally the sample ...

Sintering of kaolin in presence of ferric compound: Study by ultrasonic echography

Journal de Physique IV (Proceedings), 2005
Fine particle of iron compound has been obtain by precipitation of ferric ions in a kaolin suspension. Theses particules located on the kaolinite platelets surface, were transformed into hematite near 300°C during a thermal treatment in air. This hematite located on platelets surface, influences the thermal evolution of kaolinite only after the ...

Mössbauer Effect Studies of Electronic Relaxation in Ferric Compounds

1974
The Mossbauer spectra of several paramagnetic ferric compounds consist of a relaxation broadened singlet or quadrupole doublet. The examination of the field dependence and the temperature dependence of these spectra makes it possible to study several effects.
