Updating the view: an account about of collections management and the use of ar...

In 2020, the Laboratório de Ensino e Pesquisa em Antropologia e Arqueologia/LEPAARQ, at the Universidade Federal de Pelotas, is reaching exactly twenty years of existence. Our objective in this work is to bring a brief history of this consolidation process, over the last few years, from the technical perspective that we have adopted for the management of archaeological collections in this institution. By sharin...

Bioelectrochemical energy storage in a microbial redox flow cell

Bioelectrochemical systems (BESs) can be used to transform the electrochemical energy of fuels in electricity in Microbial Fuel Cells (MFC). However, this generated bioenergy can be captured by external loads or dissipated as heat, instead of being utilized or stored. A Microbial Redox Flow Cell (MRFC) is here presented, which demonstrates the integration of a BESs with a Redox Flow Cell (RFC); it is an innovat...

Microbially charged redox flow batteries for bioenergy storage

Microbially-charged electrochemical fuel for energy storage in a redox flow cell

A Bioelectrochemical System (BES) is used for charging an electrochemical fuel to be used in a Redox Flow Cell (RFC), demonstrating the first proof of concept of a microbially-charged electrochemical fuel. Geobacter sulfurreducens, electroactive bacteria, was used to charge anthraquinone-2,6-disulfonate (2,6-AQDS) producing current densities of ca. 200–500 mA m 2 and maximum power densities of ca. 33 mW m 2 . T...

No. of bitstreams: 0 Previous issue date: 2019-01-15; Objective: Our study evaluated the performance of different two-chambered microbial fuel cell (MFC) prototypes, operated with variable distance between electrodes and Nafion membrane and specific inoculum concentration, applied for vinasse treatment. Results: The performance of the developed MFC resulte...

Microbial fuel cell-induced production of fungal laccase to degrade the anthraq...

Made available in DSpace on 2019-10-06T15:39:25Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-09-01; The anthraquinone dye Remazol Brilliant Blue R is largely used in the textile industry. However, its removal from wastewaters is costly and complex. Many methods have been tested to solve this ecological problem, but there is still a need for efficient methods. We propose here an alternative use of a tw...
