POS-DOC POSITION FOR RESEARCH IN ELECTRO-OXIDATION OF ETHANOL, GLYCEROL AND OTHER ORGANIC MOLECULES


There is one Pos-Doc position, for two years, to work in the project: Proc 013/16930 "ELECTROCATALYSIS V: Electrocatalytic Processes of Chemical and Electrical Energy Interconversion", sponsored by Fundação de Amparo a Pesquisa do Estado de São Paulo. Application can be made for the development of the following project:

INSTITUTION
University of São Paulo
Institute of Chemistry of São Carlos (www.iqsc.usp.br)
Electrochemistry Group (http://dfq.iqsc.usp.br/grupo/?id=17, in portuguese)
São Carlos, SP
Brazil

PROJECT
Supervisor: Prof. Dr. Germano Tremiliosi-Filho (germano@iqsc.usp.br)
Summary: The research aims to perform fundamental studies specially on the mechanistic aspects of the electro-oxidation reactions of ethanol, glycerol, and other organic molecules Cn on well-defined single crystal surfaces. It also contemplates the synthesis and characterization of nanostructured electrocatalysts formed by the combination of metals and oxides of noble metals and non-noble catalysts for the oxidation reactions of ethanol, glycerol, and other organic molecules Cn, with and without photon assistance. These electrocatalytic and photoelectrocatalytic studies, in a fundamental level, will involve quantitative determination of the reaction intermediates and products by in situ FTIR spectroscopy, on-line differential electrochemistry mass spectrometry, liquid and ion chromatographies. Gas chromatography also can be employed using electrochemical half-cell with stagnant and flow (under conditions of controlled mass transport) electrolytes. The investigations will include correlations between electrocatalytic and photoelectrocatalytic activity and stability with the composition and structure of the nanoparticles. The applied studies will be carried out in a PEM type unitary fuel cell using electrodes of 5 cm ² feed with ethanol or glycerol at the anode and oxygen at the cathode, for evaluation of current density and energy efficiency. Current distribution measurements will be made in order to improve the conditions of preparation of the membrane electrode assembly (MEA), with the focus on the cell operation conditions. These studies will also involve the quantitative determination of the reaction products using techniques such as mass spectrometry, gas, liquid and ion chromatographies. These operational studies on fuel cells with and without UV light assistance will be carried out on the most active electrocatalysts and photoelectrocatalysts investigated in the previous stages.

REQUIRIMENTS
Candidates must demonstrate previous experience in studies of electrocatalysis and/or photoelectrocatalysis of the oxidation reactions of alcohols with the aim of applications in fuel cells. For registration the following documents should be sent, in pdf format, to the project supervisor at the above mentioned electronic address by March 15th, 2017:
1) Letter of Recommendation;
2) Letter at which the candidate describes his experience in the research field;
3) Copy of the Abstract of his PhD thesis;
4) Resume.

SUMMARY OF THE THEMATIC PROJECT

This research project aims at studying the electrocatalytic processes related to electrochemical systems for the chemical and electrical energy interconversion, in galvanic and electrolytic devices. The main focus is associated to the study of reactions involved in electrocatalysis for fuel cells feed with organic and inorganic molecules, metal / air batteries, regenerative electrochemical systems, hydrogen production and electro-reduction of carbon dioxide. Some fundamental aspects of the electrocatalysis and kinetic instabilities of these reactions will be investigated on single crystals and nanostructured metal electrocatalysts. The investigations will include correlation between the electrocatalytic activities and stabilities with the composition and structure of the nanoparticles. Finally, operational electrochemical investigations will be made on operating systems built using the most active electrocatalysts investigated in the previous studies. The project will be conducted by a team composed of permanent members including 6 professors/researchers, 2 researchers, 2 scientific technicians and 40 temporary collaborators such as post-docs, PhD and master students, and undergraduate students, mostly from the Institute of Chemistry of Sao Carlos, USP.

Postdoc position in Electrochemical Surface Science

In the framework of a new EU project, a postdoctoral position is available in the Surface Physics Group of the Institute of Applied Physics, TU Wien.

The project aims to clarify structure–reactivity relationships of well-defined, atomically smooth, oxide surfaces towards important electrocatalytic reactions (in particular oxygen reduction and CO2 activation), using a combination of electrochemistry (voltammetry, electrochemical STM) and ultrahigh vacuum techniques (XPS, LEED, UHV-STM). The candidate will be jointly supervised by Prof. Ulrike Diebold and Dr. Stijn Mertens.

The ideal candidate has a PhD in physics, chemistry or a related discipline, with a detailed knowledge of electrochemical techniques. A working knowledge of ultrahigh vacuum methodologies is desirable. Excellent writing and communication skills in English are essential.

This position is available immediately. Applications with cover letter, detailed CV (with courses taken, grades, web link to the PhD thesis, copies of the 5 most relevant publications), diplomas, work certificates (if any) and references should be sent via email to Stijn Mertens at mertens@iap.tuwien.ac.at.

PhD Position – Electrochemistry/Materials Science -Starting Date: September-October 2017


Electrochemical Silicon Nanoprocessing for the Fabrication of Functional Surfaces


Silicon micro- and nanostructuration is of crucial importance for microelectronics, solar cells and for promising emerging technologies in nanoelectronics, biosensing devices and water-splitting cells. These applications make the fabrication of Si nanostructured arrays a very hot topic that has attracted tremendous attention. In this context, templated electrochemistry, which can be operated in ambient conditions, enables the simultaneous fabrication of individual nanostructures at designated spots on a large area is very attractive for manufacturing such arrays.

 

We are looking for a highly-motivated PhD candidate to work on a 3-year project at the ISCR (Institut des Sciences Chimiques de Rennes), located at the University of Rennes in France. The research project is focused on the development of silicon structuration processes for the fabrication of functional surfaces. More specifically, the candidate will use electrochemical techniques such as templated photoelectrochemical etching and nano-electrodeposition in order to fabricate well-defined arrays of i) silicon nanowires and ii) silicon nanoporous microcells. He will then functionalize these surfaces with redox active molecules and study their electrical and photoelectrochemical properties. The final goal is to use these functional surfaces for biodetection and microelectronic devices.


The project duration is 3 years and the founding is provided by the ANR (Agence Nationale de la Recherche). The salary is ∼1400 € per month. The successful candidate will have an access to the equipment present at the ISCR (scanning probe microscopy, electron microscopy, potentiostats, ellipsometer, FTIR, XRD...) and to the clean room facilities located at the IETR (Institut d’Electronique et de Télécommunication de Rennes), that is located very close to the ISCR.
The candidate must have a strong background in physical chemistry and/or materials science and an interest for electrochemistry. A strong motivation for research and good communication skills are required (fluent English or French speaking is mandatory).
