June 21st-22nd is Self-Assembly at ICMAB (SELF2016), the conference on self-assembly within the ICMAB. The topics covered include self-assembly of nanoparticles, nanostructures onto surfaces, and organic molecules, and theory and simulation of self-assembly, among others.
Anna Laromaine will give a talk (Tuesday, June 21st, 12.00) on “Albumin self-assembled on iron oxide nanoparticles’ surfaces”.

Laura Asturias will give a talk at the 16th International Conference on Electroanalysis (ESEAC 2016), which will take place between 12th-16th June in Bath. 2016 represents the 30th Anniversary of the meeting, which brings together the most outstanding research in electroanalytical chemistry from across Europe and the world.
Laura will present “Carbon-gold nanoparticles thin-film electrode for the determination of mercury in sea water“, a project she has been working on within the Common Sense project at ICMAB.

Anna Laromaine gave a seminar yesterday April 5th at the Facultat de Ciències-UAB, as part of the activities organized during the Festival of Nanoscience and Nanotechnology (10alamenos9), in which the ICMAB collaborated. The topic of the seminar was Nanomedicine, which, according to Anna, is “the use of the nanotechnology for medical applications”, such as diagnosis, medical therapies, drug delivery, tissue regeneration, and the understanding of cellular systems.
Other seminars during the festival included the following topics: Biosensors by Ma Isabel Pividori, Energy capture and thermoelectrics by Aitor Lopeandía (UAB), Nanoelectronics by Francesc Pérez-Murano (IMB-CNM), an Introduction to nanotechnology by Ma José Esplandiu (ICN2), and Nanotechnology and society by Jordi Pascual (UAB).
Anna gave the presentation “Implications of surface coating SPIONs with a pre-form protein corona” at the HINT Workshop “Nanostructured materials: coatings, surface, bioceramics/-composites membranes” that has taken place in Vilnius, Lithuania 14-16th March 2016. She also participated in the Management Committee Meeting of this COST Action.
Next Monday, February 1st, at 12 pm, Dr. Anna Laromaine, member of our group, will give the ICMAB Periodical Lecture. Anna will talk about “Caenorhabditis elegans and bacterial cellulose: exploiting nature to build materials”.
Short abstract :
Many researches have been inspired by nature, from the synthesis of materials mimicking our environment to the evaluation of materials using in vivo animal models. In this talk, I will briefly introduce two approaches that we have been working recently in the group.
First, I will present the use of the small animal model, Caenorhabditis elegans (C. elegans). The characteristics of this model organism endorse this 1 mm long nematode as an ideal living system for the primary screening of engineered nanoparticles in a standard synthetic laboratory. I will present how using the worm, we assessed iron oxide nanoparticles in a simple and facile way.
On the other hand, I will present how a bacterial strain can produce cellulose (named bacterial cellulose (BC)), of the same molecular formula as vegetal cellulose; however exhibiting a higher degree of polymerization and better crystallinity. BC also has high porosity, transparency in the UV-NIR and a high water holding capacity. I will show how we controlled its structure and fabricate nanocomposites that can respond to external stimulus.

“Colloids at Fluid Interfaces: Opportunities for Advanced Materials Synthesis”
Ali Mohraz, Associate Professor of Chemical Engineering and Materials Science, University of California, Irvine
Particle sequestration at the interface of immiscible fluids has been known for more than a century and exploited in the formulation of solid-stabilized (Pickering) emulsions for drug delivery, oil recovery, food, and personal care products, to name a few. More recently, new classes of multi-phase mixtures have emerged that exploit interfacial colloid jamming, bridging, ordering, and aggregation for the self-assembly of complex higher-order structures from colloidal building blocks, such as bicontinuous interfacially jammed emulsion gels (bijels), or bridged emulsion gels. The multiphase nature of these mixtures makes them excellent templates for the synthesis of composite materials with tunable morphology at the nano- to micrometer scales, and our group has recently demonstrated various examples of functional materials that can be derived from them. However, to expand these capabilities into a robust materials synthesis platform, the factors that mediate the mechanical stability and processability of these colloidal mixtures must be better understood. In this talk, I will review the fundamentals and recent developments in colloidal self-assembly at fluid interfaces, present a novel materials synthesis route that we have pioneered based on these concepts, and discuss the applications of our technology in electrochemical energy conversion and storage, sensing, catalysis, and tissue engineering. Finally, I will discuss our ongoing efforts to better understand the link between the microstructure, rheology, and processability of this new class of soft materials.
Ali Mohraz received his BSc, ME, and PhD in Chemical Engineering from Azad University, The City College of New York, and The University of Michigan, respectively, and his postdoctoral training at the Frederick Seitz Materials Research Laboratory at The University of Illinois in Urbana-Champaign. He is currently Associate Professor of Chemical Engineering and Materials Science at the University of California, Irvine. Dr. Mohraz’s primary research interests are in colloid science and complex fluids engineering, including colloidal assembly at fluid interfaces and microstructural evolution of complex fluids under transient large-strain deformations.
