Efficient Synthesis of Single-Chain Polymer Nanoparticles via Amide Formation
(Hindawi Publishing, 2015)
Single-chain technology (SCT) allows the transformation of individual polymer chains to folded/collapsed unimolecular soft nanoparticles. In this work we contribute to the enlargement of the SCT toolbox by demonstrating ...
Metal-Free Polymethyl Methacrylate (PMMA) Nanoparticles by Enamine "Click" Chemistry at Room Temperature
"Click" chemistry has become an efficient avenue to unimolecular polymeric nanoparticles through the self-crosslinking of individual polymer chains containing appropriate functional groups. Herein we report the synthesis ...
First-principles study of the electronic and magnetic properties of defective carbon nanostructures
Using ab initio calculations we habe carried out an extensive study of the electronic and magnetic propeerties of defects and impurities in graphene and carbon nanotubes. In particular, we have focused on the following ...
Design and synthesis of biofunctional magnetic/fluorescent glyco-nanoparticles and quantum dots and their application as specific molecular imaging probes
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2014-05-05)
[EN]Nanotechnology presents very promising characteristics for its application in the biomedicine area. By now the most advanced application of nanoparticles in medicine is the use of iron oxide nanoparticles embedded ...
Quantum Electrodynamical time-dependent density functional theory
The last two decades have witnessed increasing experimental interest in the study and control of many-electron systems strongly interacting with quantum electromagnetic fields. This includes notable experiments in the areas ...
Structural and Electronic Properties of Low-Dimensional C-Nanoassemblies and Possible Analogues for Si (and Ge)
(Hindawi Publishing Corporation, 2011)
The delocalised nature of p-electrons in carbon-based compounds has opened a huge path for new fundamental and technological developments using carbon-based materials of different dimensionality (from clusters, to surfaces, ...
Relativistic force between fast electrons and planar targets
(IOP Publishing, 2014-07-30)
The full retarded electromagnetic force experienced by swift electrons moving parallel to planar boundaries is revisited, for both metallic and dielectric targets, with special emphasis on the consequences in electron ...
Nonlinear magnetic vortex dynamics in a circular nanodot excited by spin-polarized current
(Springer International Publishing, 2014-08-08)
We investigate analytically and numerically nonlinear vortex spin torque oscillator dynamics in a circular magnetic nanodot induced by a spin-polarized current perpendicular to the dot plane. We use a generalized nonlinear ...
Response of the topological surface state to surface disorder in TlBiSe2
(IOP Publishing, 2015-02-24)
Through a combination of experimental techniques we show that the topmost layer of the topological insulator TlBiSe2 as prepared by cleavage is formed by irregularly shaped Tl islands at cryogenic temperatures and by mobile ...
