  • PhD position on Cold Molecules in Groningen, The Netherlands

    Publicado el marzo 4th, 2010 Aquiles Carattino Sin comentarios aún ...

    We are looking for a talented PhD student to join us on a new experimental
    project at the Kernfysisch Versneller Instituut (KVI) in Groningen, The
    Netherlands. Our new research group plans to investigate fundamental
    symmetries and interactions through the study of ‘cold molecules’.

    At the KVI we use precision techniques to study (radioactive) atoms and
    ions, involving atomic and nuclear physics with theoretical support. A new
    research activity that has very recently been started is the study of cold
    neutral molecules. Cold molecules are molecules that we have complete
    control over; not only their velocity, but also their internal state is very
    well defined. As the ideal experiment one can think of a high-resolution
    spectroscopic measurement on a sample of ultracold trapped molecules which
    are all in the same quantum state. In this project we will construct the
    required apparatus to achieve this goal, and aim towards a measurement of a
    tiny predicted (yet until now unobserved) effect of parity violation in
    molecules. For this application the cold molecule can be seen as a small
    laboratory that is used as a magnifying glass to show the subtle effects of
    the weak interaction. Lee la entrada completa »

  • PhD student position Optoelectronic Properties of Quantum Dot Solids

    Publicado el mayo 13th, 2009 Aquiles Carattino Sin comentarios aún ...

    PhD student position available in Delft The Netherlands

    Project title: Optoelectronic Properties of Quantum Dot Solids

    A position is available for a PhD student to study new functional metamaterials based on semiconductor quantum dots. The combination of quantum dots with different size or composition leads to optoelectronic properties that are of great promise for application in e.g. solar cells, transistors, catalysis, labeling and bio-medical testing. The project is part of a collaborative research program with the University of Utrecht and the Kavli Institute for Nanoscience in Delft.

    The project focuses on fundamental studies of electronic excited states (excitons) and charge carriers in thin films consisting of a combination of self-organizing quantum dots, such as CdSe, CdTe, PbSe, PbS, InAs. You will study the dynamics of excitons and charge carriers with femtosecond and nanosecond pump-probe laser techniques, including microwave and terahertz conductivity measurements. In addition high-energy electron pulses can be used to specifically generate charges. The aim is to provide fundamental insights into the effects of material composition on exciton and charge dynamics. You will study to which extent charge generation by photon absorption can be optimized.

    Particular attention will be paid to charge generation in donor-acceptor systems. The mechanism of motion of excitons and charges from one quantum dot to another will be characterized.

  • Doctorado o Post-doc en Mecanismos de transporte de ADN

    Publicado el julio 16th, 2008 Aquiles Carattino Sin comentarios aún ...

    PhD and Postdoctoral Positions on the Mechanisms of DNA Transport by SpoIIIE
    The single-molecule biophysics group at the CBS laboratory has a PhD and a postdoctoral position available to work on the mechanisms of DNA transport by SpoIIIE, an AAA+ ring-ATPase from Bacillus subtilis.

    We are primarily interested on the mechanisms of molecular motors that transport DNA in and between bacteria. These motors use the energy of ATP hydrolysis to processively translocate DNA between cellular compartments or different cells, and belong to the large and diverse AAA+ family of ATPases. AAA+ motors tend to form closed multimeric rings in which ATP hydrolysis and substrate movement are closely correlated and coordinated. In particular, we want to understand the general mechanisms governing translocation directionality, transduction of energy into movement, and complex assembly. In general, we are interested in understanding the larger network of genetic interactions affecting the process of DNA transport in vivo.
    The project will focus on the mechanism of SpoIIIE, a DNA translocase responsible for chromosomal translocation during sporulation in Bacillus subtilis.

    We have so far studied the behaviour of SpoIIIE translocation in vitro using single-molecule magnetic tweezers and ensemble methods, and in vivo using a novel assay for monitoring DNA translocation in real-time (Nollmann et al., 2008). The project will (1) tackle the coupling of energy transduction into movement in vitro by developing and applying novel single-molecule manipulation and atomic force microscopy methods, and (2) investigate the properties of DNA translocation in vivo by applying newly developed fluorescence microscopy methods. The project will greatly profit from in house collaborations with our single-molecule fluorescence and atomic force microscopy groups and will involve travel to work with our collaborators in France, UK and the US.
    The successful candidate will have an interest in single-molecule manipulation and fluorescence microscopy. Experience in physics, molecular biology, or biochemistry will be required. Contact: Marcelo Nollmann (, phone: +33 4 67 41 79 12)

    Publicado el mayo 2nd, 2008 Aquiles Carattino Sin comentarios aún ...

    Está abierto el concurso para cubrir una BECA Agencia para realizar el doctorado en el área de Neurociencias – Fisiología del Comportamiento Animal.

    Fecha límite para la presentación de candidatos: 10 de mayo 2008.

    Proyecto PICT 1189

    Investigador Responsable: Daniel Tomsic. Fac. de Cien. Exac. y Nat. UBA.

    Título del proyecto: Minicerebros que detectan colisiones: estudios comportamentales y neurofisiológicos en el cangrejo Chasmagnathus.

    El postulante debe ser graduado y tener especial interés en temas relacionados con la fisiología del comportamiento animal. Es deseable, aunque no imprescindible, que tenga experiencia teórica y/o práctica en neurofisiología.

    Resumen del proyecto general:
    Detectar posibles colisiones es una tarea que el sistema visual debe resolver rápidamente de manera de guiar el comportamiento. Un objeto que se acerca en trayectoria directa de colisión genera una imagen que se expande simétricamente en la retina del observador. Ya sea que el acercamiento se produzca por los movimientos del objeto hacia el observador o de éste hacia el objeto, la imagen de algo que se aproxima directa y velozmente provee a los animales de la información suficiente como para reaccionar ante la inminente colisión con maniobras anticipatorias adecuadas. La capacidad para detectar y reaccionar a este tipo de información visual está presente en la mayoría de los animales visuales, desde insectos a mamíferos. Para ésta y otras tareas el pequeño cerebro de los artrópodos aparece entonces como un dispositivo que presenta un altísimo grado de optimización y eficiencia. Esto dio origen a la idea de que entender el modo en que los minicerebros de los artrópodos adquieren y procesan la información, puede servir de guía para la implementación de diseños circuitales similares en dispositivos artificiales.

    En este proyecto, investigaremos los mecanismos neuro-computacionales que guían las respuestas anticipatorias ante objetos en colisión en un modelo experimental recientemente desarrollado en nuestro laboratorio, que ofrece ventajas experimentales no presentes en otras preparaciones (Oliva et al., J. Exp. Biol. 2007). Se trata de la respuesta de escape evocada en el cangrejo Chasmagnathus ante estímulos visuales de colisión. Esta respuesta es evocada en el 100% de los animales estimulados en el laboratorio y todos sus parámetros son fáciles de medir con gran precisión. Lo que, por ejemplo, permite relacionar el momento en que el animal toma la decisión de responder con los valores que cobra la imagen (ángulo subtendido, velocidad en la retina, etc.) en ese momento. En otras palabras, permite investigar cuáles son los parámetros del estímulo visual que son procesados por el sistema nervioso para iniciar la respuesta de evitación a la colisión. En el cangrejo, las respuestas de neuronas detectoras de colisión identificadas, pueden registrarse intracelularmente en el animal vivo y despierto, lo que brinda una gran oportunidad para investigar el modo en que estas neuronas computan los parámetros de la imagen sobre los cuales el animal detecta la colisión y toma la decisión de evitarla.

  • PhD position on joint project of University of Amsterdam and FOM Institute Rijnhuizen

    Publicado el noviembre 6th, 2007 Aquiles Carattino Sin comentarios aún ...

    Presently, a PhD position is open on a joint project between the Molecular
    Photonics group of Prof. W.J. Buma at the University of Amsterdam and the
    Molecular Dynamics group of Dr. J. Oomens at the FOM Institute Rijnhuizen.
    The project is concerned with the development of new functional systems
    that are responsive to exposure to a temperature above a threshold value
    and/or exposure to UV light. One of the approaches employed is based on
    discotic liquid crystals. The spectroscopic properties of the employed
    molecular systems have been studied to some extent in solution, liquid, and
    solid state, but the excited and ionic state, properties under isolated
    conditions, and – in particular how they change upon aggregation – are
    largely unknown.
