Final COMMON SENSE meeting and public event: Next generation sensors for ocean observation.

On Friday, January 27, there will be a public and free event to present the final results of the COMMON SENSE project on “Demonstration of next generation sensors for advanced real-time ocean observation.

This event will closure the COMMON SENSE project, in which the NN group has actively participated in the development of electrochemical sensors that are able to detect different heavy metals simultaneously

  • Date and time:
    Friday, January 27, from 9 am to 5 pm
  • Location: 
    Fundació Navegació Oceànica Barcelona (FNOB)
    1 Moll de Llevant, 08039 Barcelona (View Map)

Martí Gich and Anna Roig will participate in a previous meeting on Thursday, with the project team, and on Friday on the public event. 

Professionals working in the marine environment and citizens curious about the status of our oceans are invited!

The COMMON SENSE project is creating prototypes of next generation in-situ marine sensors to deliver vital information about the oceans. The project directly responds to the requirement for integrated and effective data acquisition systems by developing innovative sensors that will contribute to our understanding of how the marine environment functions. In doing so, COMMON SENSE results can support the implementation of European Union marine policies such as the Marine Strategy Framework  Directive (MSFD) and the Common Fisheries Policy (CFP).

As the COMMON SENSE project comes to a successful conclusion, the results will be presented at this final workshop, along with a demonstration of the novel sensors developed and tested during the project.

The COMMON SENSE sensors need less human operation and intervention than current technologies and create standardised data on eutrophication, underwater noise, heavy metals, and marine litter, with a focus on microplastics. Other important parameters considered are temperature, pressure, pH and pCO2.

Prof. Stephen Sturzenbaum will give an ICMAB Lecture on toxicity of metals on biological systems

It is a pleasure for us to invite you to the ICMAB Lecture entitled: “Juggling essential and toxic metals – a worm’s eye view of a Toxicogenomic challenge”

By Prof. Stephen Sturzenbaum from the group of Toxicogenomics from King’s College London (UK).

Date: Friday, January 20th
Time: 12.00 pm
Place: ICMAB – Sala d’actes Carles Miravitlles

Abstract: Some metals are exclusively toxic to biological systems and classified as being non-essential, others are essential for life. Nevertheless, above certain threshold concentrations all (including the essential ones) become toxic. Homeostasis of essential elements and detoxification of non-essential elements are thus vital drivers of well-being, longevity and survival. By exploiting genomic, transcriptomic and toxicological tools within the model nematode C. elegans we identified and characterized intricate pathways that not only form the foundations of metallomics but facilitate further explorations within the field of nanomaterials.

Short bio: Professor Stephen Sturzenbaum holds a personal chair in Toxicogenomics at King’s College London and was recently awarded a Senior Doctorate (DSc) from Cardiff University for his work on “Toxicogenomics on Terrestrial Worms”. Stephen pioneered the use of molecular genetic tools in the common earthworm, and in doing so was instrumental in establishing the earthworm as a sentinel soil macroinvertebrate model organism of environmental importance. Stephen’s second stream of work has focussed on promoting the use of the more established C. elegans model organism to address the burgeoning themes of metallobiology, toxicogenomics and nanoparticle toxicology. Laura González, from our group, who did her thesis on evaluating nanoparticles’ toxicity on C. elegans, did an internship at his laboratory during Feb-May 2016

How can synchrotron light be used to protect the environment? Researchers from INTE-UPC show us how.

Our collaborators from the research group NEMEN (Nanoengineering of Materials applied to Energy) at the Institue of Energy Technologies (INTE-UPC) appear in this video from ALBA Synchrotron at UPC-TV.

The video shows how the synchrotron light is used to verify the design of the catalysts and photocatalysts used either for hydrogen generation (to be used in energy applications, instead of fossil fuels), or for the removal of air pollutants (especially coming from the exhaust pipes of cars, trucks, and public transportation in cities). 

In our group we synthesize some of these photocatalysts used for hydrogen generation from water/ethanol gaseous mixtures under UV-light irradiation

First accepted manuscript of 2017, in CHEMISTRY – A European Journal


A recent manuscript entitled “A recoverable ruthenium aqua complex supported onto silica particles: an efficient epoxidation catalyst“, by M. Isabel Romero, Ingrid Ferrer, Xavier Fontrodona, Anna Roig and Montserrat Rodríguez, has been accepted in CHEMISTRY – A European Journal (Accepted manuscript online: 11 January 2017; DOI: 10.1002/chem.201604463).

This article is the product of a collaboration with the Group of Catalysis and Sustainability of the University of Girona

The article reports the synthesis and catalytic performance of hybrid materials formed by a molecular ruthenium aqua complex anchored onto silica mesoporous and silica coated magnetic particles. The catalytic results and the reutilization of these hybrid materials highlight their performance in the epoxidation of alkenes.

Abstract

The preparation and characterization of new complexes with a phosphonated trpy ligand (trpy-P-Et) and a bidentate pyridylpyrazole (pypz-Me) ligand, with formula [RuII(trpy-P-Et)(pypz-Me)X]n+ (X = Cl, n= 1, 2; X=H2O, n=2, 3) is described, together with the anchoring of 3 onto two types of supports: mesoporous silica particles (SP) and silica coated magnetic particles (MSP). The aqua complex 3 is easily obtained through reflux of 2 in water and displays a bielectronic Ru(IV/II) redox process. It has been anchored onto SP and MSP supports through two different synthetic strategies, yielding the heterogeneous systems SP@3 and MSP@3 that have been fully characterized by IR, UV-vis, SEM, CV and DPV. Catalytic olefin epoxidation has been tested with the molecular complex 3 and the SP@3 and MSP@3 heterogeneous counterparts, including the reuse of the heterogeneous systems. The MSP@3 material can be easily recovered by a magnet facilitating their reusability.

INPhINIT “La Caixa” Fellowship Programme – Opportunities at ICMAB-CSIC within the NN Group

INPhINIT is a new doctoral fellowship programme promoted by “la Caixa” Foundation devoted to attract international Early-Stage Researchers to the top Spanish research centres in the areas of Bio and Health Sciences, Physics, Technology, Engineering and Mathematics.

INPhINIT recruits per call 57 Early-Stage Researchers of any nationality, who enjoy a 3-year employment contract at the Research Centre of their choice among those selected and awarded by the Spanish Ministry of Economy and Competitiveness (“Severo Ochoa” centres of excellence and “Maria de Maeztu” units of excellence) and the Spanish Ministry of Health (“Carlos III centres of excellence”).

ICMAB-CSIC is one of the “Severo Ochoa” centers selected, and has published 24 PhD open positions under the INPhINIT programme. 

One of this projects is offered by Anna Roig and Martí Gich, within the NN Group, and is entitled “Mesoporous Magnetic Nanorods for Theranostics”

The project aims at developing high aspect ratio magnetic silica-based materials as multimodal agents for theranostic purposes. The targeted materials are mesoporous silica rods containing inorganic nanoparticles to serve as contrast agents for magnetic resonance imaging and computed tomography and at the same time encapsulating selected drugs.  The project aims at demonstrating that engineered magnetic objects in the rod shape can constitute a new family of carriers for therapeutic agents with radically new properties and advantages compared to the magnetic nanoparticles used so far.

Application deadline: 2 Februrary 2017
