Electrical resistance of gas fluidized natural flake graphite

Alexandre Bernard, Marc Duchesne, Jan B. Haelssig, Arturo Macchi

Resistance and bulk resistivity of three commercial grades of fluidized natural flake graphite were determined with a high-frequency data acquisition system at ambient conditions and low voltage. Resistance was measured for up to 5 h over a wide range of superficial gas …

Electrically Heated Fluidized Bed for Graphite Purification: Heat Transfer and Electric Resistivity Models for Scale-Up

Imtiaz Ahmed, Serhii Fedorov, Artem Sybir, Semen Hubynskyi et autres

Abstract Electrothermal purification is an effective method for achieving over 99.9 pct purity for graphite particles with minimal environmental impact. However, the lack of a suitable heat and electric resistivity model has hindered the scaling up of electrically heated fluidized bed (EHFB) …

Ultrahigh Temperature Purification of Graphite for the Development of a Continuous Process

Yewen Tan, Marc Duchesne, Anna Doninger, Igor Barsukov

This work presents a study of ultrahigh temperature purification of natural Canadian graphite flakes. The concentrated natural graphite flakes were purified using two test facilities, an ultrahigh temperature fixed bed furnace and an ultrahigh temperature fast-heating counterflow reactor. With the fixed bed …

A generalized analytical energy balance model for evaluating agglomeration from a binary collision of wet particles

Jaber Shabanian, Marc Duchesne, Madhava Syamlal, Allan Runstedtler

Agglomeration of wet particles, i.e., particles coated with a thin liquid layer, is a common phenomenon in many processes like fluidized bed combustion of low rank fuels. The availability of an agglomeration model that can evaluate the outcome of a binary collision …

The compact genome of the sponge Oopsacas minuta (Hexactinellida) is lacking key metazoan core genes

Sébastien Santini, Quentin Schenkelaars, Cyril Jourda, Marc Duchesne et autres

BACKGROUND: Explaining the emergence of the hallmarks of bilaterians is a central focus of evolutionary developmental biology-evodevo-and evolutionary genomics. For this purpose, we must both expand and also refine our knowledge of non-bilaterian genomes, especially by studying early branching animals, in particular …
