From 17th to 21th of April, Phoenix will host the Spring Meeting and Exhibit of the Materials Research Society (MRS). In this huge congress the following topics will be addressed:

Characterization, Theory and Modeling
Electronic Devices and Materials
Energy Storage and Conversion
Nanomaterials
Soft Materials and Biomaterials

Anna Roig is invited to give a talk named:

Engineering Bacterial Cellulose Nanocomposites—Aerogel-Inspired Biopolymers.

The N&N group has a great expertise in producing and characterizing bacterial cellulose, and in creating multiple nanocomposites based on this biopolymer. The group will also be represented by Anna Roig with two more oral communications:

Phoenix is the capital city of Arizona (USA) and it is also called “The Valley of the Sun”

Simple approaches to synthesize hybrid nanoparticles with magnetic and plasmonic functionalities, with high control of their shape and avoiding cytotoxic reactants, to target biomedical applications remain a huge challenge. Here, we report a facile, fast and bio-friendly microwave-assisted polyol route for the synthesis of a complex multi-material consisting of monodisperse gold nanotriangles around 280 nm in size uniformly decorated by superparamagnetic iron oxide nanoparticles of 5 nm. These nanotriangles are readily dispersible in water, display a strong magnetic response (10 wt% magnetic fraction) and exhibit a localized surface plasmon resonance band in the NIR region (800 nm). Moreover, these hybrid particles can be easily self-assembled at the liquid–airinterfaces.
