Contract - Photoemission spectroscopy and microscopy beamline

Consortium CELLS

Barcelona, Spain

Deadline: 2014/03/28

Description

ALBA is the Spanish 3-GeV synchrotron radiation facility operated by the Consortium CELLS, which is equally funded by the Spanish Government (Ministerio de Economía y Competividad) and the Catalan Government (Generalitat de Catalunya, Departament d'Economia i Coneixement). Out of the seven operating phase I beamlines, BL24-CIRCE is a variable polarization, soft X-ray beamline dedicated to photoelectron spectroscopy and microscopy. 

The beamline has two branches equipped respectively with endstations for PhotoElectron Emission Microscopy (PEEM) and Near Ambient Pressure Photoemision spectroscopy (NAPP) . 

The Near-Ambient Pressure Photoemission (NAPP) endstation is an Ultra High Vacuum (UHV) setup equipped with a hemispherical electron energy analyzer for X-ray Photoelectron Spectroscopy (Phoibos NAP150 from SPECS) that can operate at a sample pressure range from UHV up to 25 mbar thanks to a differential pumping system which ensures a pressure difference of 109 between detector and sample [http://rsi.aip.org/resource/1/rsinak/v73/i11/p3872_s1]. 

Therefore the usual characterization capabilities of XPS are extended to the study of gas-solid and gas-liquid interphases, with applications to in-situ characterization of heterogeneous catalysts, corrosion processes, wetting, fuel cells, photovoltaics, etc.

The beamline is open to worldwide scientific community since 2012. The scientific staff of the beamline is responsible to give support to academic and industrial users and is also in charge of the maintainance and continuous upgrade of the beamline.

The beamline scientists are encouraged to carry on a scientific programme using the capabilities of the beamline. 

In the forecoming years the in-house research program for the NAPP will include the following topics:

- Supramolecular self-assembly of organic molecules in near ambient conditions.

- Photoemission and X-ray Absorption of organic molecules in solutions, including the implementation of a microjet generator for the NAPP endstation.

- Tailoring catalytic properties of metallic nanoparticles under reaction conditions.

The successful candidate will:

* Provide Local Contact support in experiments to scientific groups using the CIRCE beamline, mostly on the NAPP endstation.

* Develop an in-house scientific program focused on the NAPP end station.

* Maintain the beamline together with the rest of the beamline team.

* Participate in projects to continuously improve and upgrade the beamline, notably regarding the NAPP end-station setup.

Early Stage Researcher - Optical tweezers for kinetochore-microtubule interaction

University of Dundee

Scotland, United Kingdom

The deadline for applications is 31st March, 2014.

Description

Early Stage Researcher – MARIE CURIE RESEARCH FELLOW

Project Name: Optical tweezers for kinetochore-microtubule interaction

Summary of Job Purpose & Principal Duties:

This is a unique and exciting opportunity to participate in a European project entitled PHOQUS: 

PHOtonic tools for Quantative imaging in tissUeS. This 3-year PhD programme is a new, highly innovative scheme to train postgraduate students as truly interdisciplinary scientists either as "problem oriented physicists” or "solution oriented biologists".

The PHOQUS project will utilise the University of Dundee’s extensive and world-class expertise in Life Sciences, pioneering work in the Medical School and advanced Photonics to deliver an Innovative Doctoral Training Program directed at the development and application of novel imaging modalities to enable the quantitative investigation of biological processes from the molecular and cellular to the tissue and organ level scale. The training programme will lead automatically to advances and new knowledge on how to harness these new technologies and new strategies. The PHOQUS project is strongly interdisciplinary, with close involvement of 10 Associated Partners and 9 Academic Partners distributed over 7 European countries. 

In the ESR6 project of the PHOQUS programme, a student will study dynamic kinetochore-microtubule interaction in vitro. To maintain genetic information, cells have to inherit the whole set of chromosomes when they multiply. This process relies on correct kinetochore-microtubule interaction during mitosis. The aim of the project is to reconstitute kinetochore-microtubule interaction in vitro using optical tweezers. This research will be undertaken in Prof Tomo Tanaka and Dr David McGloin’s groups in the University of Dundee, Dundee, UK. The successful candidate will also undertake short-term secondments to associate partners and collaborators.

Contract for software developer in microscopy

CNB-CSIC I2PC

Madrid, España

Description

We are looking for a software developer at the INSTRUCT Image Processing Center in Microscopy, CNB-CSIC, Madrid, technically oriented candidate (engineer, physicist, mathematician, computer scientist...) to work in the development of a software platform to integrate several image processing software packages in electron microscopy.

Background: INSTRUCT is the European Strategic Initiative in the area of Structural Biology. It is organized around 5 Core Centers and a similar number of Associated Centers. During 2009 the Biocomputing Unit (BCU) of the CNB-CSIC won the international competition to become the "INSTRUCT Center for Image Processing in Biology", starting its operation during 2010 and providing the context for this opening of positions. The BCU is well known in the area of three dimensional electron microscopy, with over 150 publications in the area, including public domains suites of programs and very popular image processing methods. The I2PC is also focused in the development of a large range of services for the structural-biologist community, such as 3DEMbenchmark, Scipion or Pepper.

Requirements

• BS or Master in Computer Science, engineer, physicist, mathematician or equivalent degree.
• Programming experience with Python (C/C++ is a plus).
• Experience in GNU Linux OS.
• Experience in collaborative development (git, svn, etc).
• Medium level of proficiency in written and spoken English.

The following skills are considered a “plus”, but are not essential:

• Experience in Web applications with the Django framework.
• Experience in Desktop applications with Python/Tkinter.
• Technical experience with workflows engines.
• General background on image processing (electron microscopy knowledge is an additional “plus”).
